- Home range and habitat selection are key subjects when studying animal ecology. Defining the space use and resource management of an animal establishes a solid basis for further behavioural and ecological research, as well as conservation management. Studies focusing on determining home range and habitat selection often include further questions regarding for example conservation, animal movement, population dynamics, and inter- or intraspecific interactions. It is therefore unsurprising that home range and habitat selection have been the focus of numerous studies on different vertebrate taxa over the years. We have reviewed 903 publications, on all extant vertebrate clades focusing on these topics from 1980 to the first quarter of 2018. We have observed that allocation of vertebrate orders are independent of species richness, relatedness, and portion of threatened species within the order. We have highlighted the relationship between publication numbers and species richness and offer ideas for future research in proposing possible causes for the observed allocation and in highlighting understudied clades. Furthermore, we have observed that topics often studied in concordance with home range and habitat selection are conservation and human influence, intraspecific differences, and home range shifts/exploratory behaviour. Meanwhile, topics like population density, reproductive behaviour, territoriality/aggressive behaviour, and interspecific interactions seem to be less studied. This review highlights and discusses the current distribution of focal points in studies concerning home range and habitat use while identifying less studied fields and taxa – thereby emphasizing potential opportunities for further research.

- Based on the species specificity of anuran vocalization, bioacoustics can be utilized in terms of species identification and species delimitation. The genus Theloderma comprises 23 to 29 species, depending on inclusion of the (sub)genera Nyctixalus and Stelladerma, from which the majority of 14 species was described in this century. In spite of numerous publications about species descriptions and phylogenetics, studies about life history traits, particularly about advertisement calls, are lacking for the most species. In this study, acoustic signals of the mossy or bug-eyed frogs Theloderma corticale, T. albopunctatum and T. licin were recorded, and detailed temporal and spectral advertisement call properties are presented and compared to other congenerics (T. auratum, T. stellatum, T. vietnamense). We found that the advertisement calls of the six herein compared species are species-specific and are significantly distinguishable from each other. While the temporal features (i.e. arrangement in call groups, note repetition rate) are species-specific call properties, the spectral features (i.e. dominant frequency) can partially overlap among the small-sized species.

Journal of Experimental Zoology – Part A: Ecological and Integrative Physiology 2020: 158-172. (PDF) Abstract
- One principle threat prompting the worldwide decline of amphibians is the introduction of nonindigenous amphibians. The African Clawed Frog, Xenopus laevis, is now one of the widest distributed amphibians occurring on four continents with ongoing range expansion including large parts of Europe. Species distribution models (SDMs) are essential tools to predict the invasive risk of these species. Previous efforts have focused on correlative approaches but these can be vulnerable to extrapolation errors when projecting species’ distributions in nonnative ranges. Recent developments emphasise more robust process‐based models, which use physiological data like critical thermal limits and performance, or hybrid models using both approaches. Previous correlative SDMs predict different patterns in the potential future distribution of X. laevis in Europe, but it is likely that these models do not assess its full invasive potential. Based on physiological performance trials, we calculate size and temperature‐dependent response surfaces, which are scaled to geographic performance layers matching the critical thermal limits. We then use these ecophysiological performance layers in a standard correlative SDM framework to predict the potential distribution in southern Africa and Europe. Physiological performance traits (standard metabolic rate and endurance time of adult frogs) are the main drivers for the predicted distribution, while the locomotor performance (maximum velocity and distance moved in 200 ms) of adults and tadpoles have low contributions.

- The pathways of introduction of non-native amphibians are diverse, as historically amphibians were used as pest control agents, food stock, or were introduced to perform research. Today, the pet trade is the main source for amphibian introductions into novel ranges. However, these introductions mainly concern anurans, whereas cases involving urodeles are less common. Since 2013, a population of European cave salamanders, Speleomantes spp. Dubois, 1984, is known to be present in Germany. However, knowledge on the size of this population is missing, and it is unknown to which of the similar-looking species of Speleomantes it belongs. Here, we applied loglinear capture-recapture models to estimate population size, and used a recently published photographic database, including more than 1000 images of all eight Speleomantes species, to determine the species identity of the German population. According to our estimates, the population consists of 170 to 485 individuals (±134 to 320). Based on colour pattern the population most likely belongs to S. italicus (Dunn, 1923). We additionally provide the first evidence for reproduction and give further insights into this non-native salamander population.

- Invasive species, such as the mainly aquatic African clawed frog Xenopus laevis, are a main threat to global biodiversity. The identification of dispersal corridors is necessary to restrict further expansion of these species and help to elaborate management plans for their control and eradication. Here we use remote sensing derived resistance surfaces, based on the normalised difference vegetation index (NDVI) and the normalised difference water index (NDWI) accounting for behavioural and physiological dispersal limitations of the species, in combination with elevation layers, to determine fine scale dispersal patterns of invasive populations of X. laevis in Portugal, where the frog had established populations in two rivers. We reconstruct past dispersal routes between these two invaded rivers and highlight high risk areas for future expansion. Our models suggest terrestrial dispersal corridors that connect both invaded rivers and identify artificial water bodies as stepping stones for overland movement of X. laevis. Additionally, we found several potential stepping stones into novel areas and provide concrete information for invasive species management.

- Species demanding specifc habitat requirements sufer, particularly under environmental changes. The smallest owl of Africa, the Sokoke Scops Owl (Otus ireneae), occurs exclusively in East African coastal forests. To understand the movement behaviour and habitat demands of O. ireneae, we combined data from radio-tracking and remote sensing to calculate Species Distribution Models across the Arabuko Sokoke forest in southern Kenya. Based on these data, we estimated the local population size and projected the distribution of current suitable habitats. We found that the species occurs only in Cynometra woodland with large old trees and dense vegetation. Based on home range sizes and the distribution of suitable forest habitats, the local population size was estimated at<400 pairs. Ongoing selective logging of hard-wood trees and the production of charcoal are reducing habitat quality of which will reduce the low numbers of O. ireneae, and of other specialist forest species, even further. Due to their close connection with intact Cynometra forest, O. ireneae is an excellent indicator of intact forest remnants. In addition, this species is a suitable fagship for the promotion and conservation of the last remaining coastal forests of East Africa.

Modeling the environmental refugia of the endangered Lichtenfelder’s Tiger Gecko (Goniurosaurus lichtenfelderi) towards implementation of transboundary conservation. Frontiers of Biogeography3.4, e51167. (PDF) Abstract
- Climate change has potential effects on global biodiversity by shifting the optimal distribution of terrestrial organisms, particularly species with narrow distributions. Goniurosaurus lichtenfelderi, a forest-dwelling lizard, is found on both the island and mainland sites of northern Vietnam and southern China. The species is categorized as Vulnerable in the IUCN Red List and was recently listed in CITES Appendix II and the Vietnam Government’s Decree 06 in 2019 due to severe anthropogenic impacts on its populations. In this study, we employ Maxent species distribution modeling with climatic and vegetation cover data to identify the potential distribution of G. lichtenfelderi. We also used this approach to assess future climate impacts on the potential distribution under different climate change scenarios. Our model predicts that the potential distribution of G. lichtenfelderi will shrink significantly under future scenarios and even vanish in the entire study area under novel environmental conditions of the BCC-CSM 1-1 – RCP 8.5 scenario by the 2070s. Overall, the current potential distribution is expected to shift towards higher latitudes within the next decades. The forecasted maps provide useful guidelines to implement conservation strategies to mitigate synergistic impacts from climate change and other negative anthropogenic activities. In the context of the potentially severe impacts, the border areas between China and Vietnam, Yen Tu Mountain Range, Bai Tu Long National Park, and their surroundings should be considered core refugia for the species, where conservation measures need to be prioritized in the future.

- Climate change impacts biodiversity and is driving range shifts of species and populations across the globe. To understand the effects of climate warming on biota, long-term observations of the occurrence of species and detailed knowledge on their ecology and life-history is crucial. Mountain species particularly suffer under climate warming and often respond to environmental changes by altitudinal range shifts. We assessed long-term distribution trends of mountain butterflies across the eastern Alps and calculated species’ specific annual range shifts based on field observations and species distribution models, counterbalancing the potential drawbacks of both approaches. We also compiled details on the ecology, behavior and life-history, and the climate niche of each species assessed. We found that the highest altitudinal maxima were observed recently in the majority of cases, while the lowest altitudes of observations were recorded before 1980. Mobile and generalist species with a broad ecological amplitude tended to move uphill more than specialist and sedentary species. As main drivers, we identified climatic conditions and topographic variables, such as insolation and solar irradiation. This study provides important evidence for responses of high mountain taxa to rapid climate change. Our study underlines the advantage of combining historical surveys and museum collection data with cutting-edge analyses.

A present and future assessment of the effectiveness of existing reserves in preserving three critically endangered freshwater turtles in Southeast Asia and South Asia. Frontiers of Biogeography 2021, 13.4, e50928. (PDF) Abstract
- Tortoises and freshwater turtles are among the most threatened taxa of vertebrates in the world due to consumption, urban development, agriculture, and land and water pollution. About 50% of the currently recognised chelonian species are considered threatened with extinction according to the IUCN Red List. Asia is an epicentre for the turtle and tortoise extinction crisis, containing the highest diversity of threatened species. In thisstudy, we used species distributionmodels(SDMs) to assessthe effectiveness of existing protected areas across Southeast and South Asia for the conservation of three large critically endangered freshwater turtles (Batagur borneoensis, B. affinis, and Pelochelys cantorii).Wederived the models based on selected bioclimatic variables at the sites of known species records. Our SDMs showed that Indonesia is of particular importance in prioritising conservation forthese three species, containing the largest areas of suitable habitat within protected areas. However, when considering water surface coverage, Thailand has the highest proportion ofsuitable areas under protection. Our results suggest that the present cover of protected network reserves seems inadequate in terms of size and should be expanded to sustain populations of the three target species. Therefore, we identified priority areas and reserves critical forfurther field surveysto guide the potential discovery of novel populations. To investigate the effect of climate change, we also projected potential distributions onto ensembles of four IPCC story lines. As a result, we found larger extralimital areas of suitable environmentfor allthree species, particularly northwards and inland. However, high degrees of uncertainty in climate conditions indicate few reserves may provide long term protection. Lastly, we review the threats and propose recommendations for conservation ofthese poorly known freshwater turtles.

Journal of Experimental Zoology – Part A: Ecological and Integrative Physiology 2020: 13-44. (PDF) Abstract
- Research on the thermal ecology and physiology of free‐living organisms is accelerating as scientists and managers recognize the urgency of the global biodiversity crisis brought on by climate change. As ectotherms, temperature fundamentally affects most aspects of the lives of amphibians and reptiles, making them excellent models for studying how animals are impacted by changing temperatures. As research on this group of organisms accelerates, it is essential to maintain consistent and optimal methodology so that results can be compared across groups and over time. This review addresses the utility of reptiles and amphibians as model organisms for thermal studies by reviewing the best practices for research on their thermal ecology and physiology, and by highlighting key studies that have advanced the field with new and improved methods. We end by presenting several areas where reptiles and amphibians show great promise for further advancing our understanding of how temperature relations between organisms and their environments are impacted by global climate change.

- To manage populations of threatened species according to the IUCN’s One Plan Approach, knowledge about both in-situ and ex-situ populations is required. To enhance the conservation of threatened skinks and to gain an overview of which skink species are kept in zoos, and thus already have an ex-situ conservation component, we analysed data from the Zoological Information Management System (ZIMS): their individual numbers, breeding success, and the number of holding institutions. We categorized species as threatened or non-threatened based on IUCN Red List assessments. Only 92 (~5%) of 1727 recognized skink species are held in ZIMS institutions worldwide, mostly in Australia, Europe, and North America. 77% of the species kept globally are classified as non-threatened and ~23% (21 species) are threatened. Only 28% of the species kept have successfully bred in the last year, mostly in one zoo each. Of these seven species were threatened. All threatened species are kept by four zoos at most, generally only in one. Half of the skink species kept are represented by less than 10 individuals. Mainly Australian skink species were kept. To improve the conservation of threatened skinks, a shift towards keeping threatened species should be considered within captive management programmes. European and North American zoos offer capacities and expertise for skink conservation but are outside skink species richness hotspots. Cooperative projects with institutions and stations in such hotspots could greatly benefit the conservation of skinks. Thus, according to the One Plan Approach, the ex-situ populations could directly contribute to in-situ protection.

- Paradactylodon, a genus of Hynobiidae, is distributed in mountainous regions of the Middle East. This genus comprises three species, Paradactylodon mustersi (Afghanistan), Paradactylodon persicus, and Paradactylodon gorganensis (Iran). Initially, P. persicus was reported from Talysh Mountains, and afterward, P. gorganensis was described from the eastern Alborz Mountains. Although these two Iranian Paradactylodon species were distinguished based on morphological features, there are arguments about their systematic status. In this contribution, 30 samples of hynobiid salamanders were collected from Talysh and Alborz Mountains and the phylogenetic relationship between the two species was assessed using two mtDNA markers (COI and 16S). Additionally, in order to survey the potential habitat suitability for the species, Species Distribution Models (SDMs) were performed and projected on climate scenarios that reflect current and past (6 ky and 21 ky before present) conditions. Our results indicated that P. gorganensis is nested within P. persicus. Overall, both SDM and molecular analyses suggest that the Iranian Paradactylodon population was affected by the Quaternary glacial period, and according to haplotype networks, haplotype diversity was higher in the western part of the distribution range of the species. Given the low genetic distance among all samples, we suggest P. gorganensis be synonymized with P. persicus. Considering the conservational values and numerous threats that this endemic species is facing, we encourage a revision of the IUCN Red List category of the species immediately.

- The Tylototriton asperrimus complex from northern Vietnam is reviewed based on morphological comparisons and analysis of the mitochondrial marker NADH dehydrogenase subunit 2 (ND2). Based on molecular divergences, which were revealed to be higher than in other congeners, in concert with morphological differences, two new species and one subspecies are described herein: Tylototriton pasmansi sp. nov. differs from T. asperrimus sensu stricto by 3.2 to 3.6 % genetic divergence and a combination of distinct morphological characters, such as head slightly longer than wide, distinct mid-dorsal ridge, relatively wide distance between the eyes, tips of fingers reaching the eye when foreleg is laid forward, labial and gular folds present, central belly skin with tubercles shaped like transverse wrinkles and distinct, pointy to round rib nodules. The population of T. pasmansi sp. nov. consists of two subclades, the nominotypic one occurring on the eastern side of the Da River (or Black River, including Hoa Binh and Phu Tho provinces), and another occurring on the western side (including Son La and Thanh Hoa provinces). These two subclades differ by 2.5 to 3.1 % genetic divergence and distinct morphological characters. The western subclade is herein described as Tylototriton pasmansi obsti ssp. nov., which differs from the nominotypic form by a wider head, longer and narrower snout, shorter femur length, and an overall less granulose skin, without an increased concentration of warts on the body sides. A second new species, Tylototriton sparreboomi sp. nov. is described from Lai Chau Province. It differs from T. asperrimus sensu stricto by 4.1 to 4.2 % and from Tylototriton pasmansi sp. nov. by 3.6 to 4.5 % genetic divergences as well as by a combination of distinct morphological characters, such as head longer than wide, tips of fingers reaching nostril when foreleg adpressed along head, rib nodules distinct, round and relatively enlarged, and wide distance between the eyes.

The past, current and future habitat range of the Spider-tailed Viper, Pseudocerastes urarachnoides (Serpentes: Viperidae) in western Iran and eastern Iraq as revealed by habitat modelling. Zoology in the Middle East, DOI: 10.1080/09397140.2020.1757910 (PDF) Abstract
- To date, at least 72 endemic reptilian species have reported from Iran including the Spider-tailed Viper (Pseudocerastes urarachnoides), which has a very limited, narrow distribution, and occurs in areas of western Iran and eastern Iraq. The potential distribution of Pseudocerastes urarachnoides in Iran for the present, the past (midHolocene and last glacial maximum), and the future (2100) was predicted by Maximum Entropy (MaxEnt) modelling using 99 occurrence records as well as 19 environmental variables derived from climate databases. For all projected potential distributions, the principal components 1 (explained primarily by thermal variables) and 2 (explained primarily by precipitation variables) contributed more than 80% collectively in all MaxEnt models. The extreme eastern distribution range of P. urarachnoides corresponds to the western slopes of the Zagros Mountains within the Iraq territories. According to the projections, the current distribution area is smaller than in the midHolocene but larger than the last glacial maximum and three out of four scenarios of the future (2100). Future projections dramatically displace the suitable habitat, leading to a mismatch between the current and future habitat range of the Spider-tailed Viper.

- The Atlantic Forest is one of the largest and richest tropical rainforests on the planet, being one of the 25 world priorities for conservation. The Atlantic Forest portion located north of the São Francisco River corresponds to the Pernambuco Endemism Center (PEC). We describe the snake composition of the PEC, providing information about the diversity, natural history and geographical distribution of the species, based on records from five scientific collections and additional information from the literature. A total of 78 species of snakes distributed in eight families was registered in the Pernambuco Endemism Center. The Caatinga is the Brazilian biome that most shares species with the PEC, followed by Cerrado. On the other hand, seven species are considered endemic of this region. Most of the snake species in the PEC have been registered in forest (94.8%), followed by “Brejos Nordestinos” (46.1%), Tabuleiros (43.5%), Restingas (14.1%) and Mangroves (5.1%). The PEC snake fauna includes mainly terrestrial species (60.2%) and cryptozoic and/or fossorial species (21.7%), but also presents a high richness of semi-arboreal and arboreal species (29.5%). Vertebrates are the main food item consumed by the species (78% of species), among the main prey are mammals, lizards, and amphibians. Most species show a strictly nocturnal activity period (50%), followed by strictly diurnal (38%). The PEC is the most degraded and least known region of the Atlantic Forest, yet it has revealed a high richness of snake species, including seven endemic species. It is emphasized that regional conservation efforts need to be intensified, because few forests in the region are formally protected, and the majority consist of small and poorly protected fragments, which means that many species in the region may be in risk of extinction.

Rapid local adaptations in an invasive frog (Xenopus laevis): the importance of functional trait measurements to predict future invasions. In: SICB 2020 Annual Meeting Abstracts, vol. 60 (Supplement 1), pp. e102. Integrative and Comparative Biology. Abstract
- The control and eradication of invasive species is an ever-increasing problem for wildlife management and conservation practitioners. Understanding the potential future spread of invasive species is critical to inform management decisions. One often used tool to predict future species distributions is species distribution modelling (SDM) under alternative scenarios of climate change. Although extremely relevant and insightful, most of these models suffer from two drawbacks: 1) the lack of physiological data describing the dependence of organisms on changes in temperature and hydric state; 2) they ignore any potential for adaptive differentiation of invasive populations. To test what the effect could be of these two parameters we focused on invasive populations of the invasive amphibian, Xenopus laevis. We collected data on anatomy and physiology (temperature dependence of performance traits) for animals from the source population as well as invasive populations. These data were then used to inform SDMs that predict future spread under different climate change scenarios and to test for the potential adaptive divergence of invasive populations relative to the native population in morphology and physiology. Our results show that incorporating physiological data in SDMs does provide different predictions on future distribution ranges with a much higher invasion potential than previously estimated. Furthermore, our results show rapid (less than 30 years) changes in morphology and physiology in different populations suggesting local adaptation. These results stress the importance of using biologically informed data to inform conservation practices.

- In 2008, the European Association of Zoos and Aquaria and Amphibian Ark proclaimed the ‘Year of the Frog’. In the present study, based on analyses conducted in April and May 2017, the selection of amphibian species in zoos was investigated almost 10 years after that campaign. Given the huge diversity of amphibians, their representation in zoological collections was still poor, with only around 7% (540 species) of all extant amphibian species kept in zoos (76% anurans, 22% caudates and 2% caecilians). Only 10.4% of the amphibians in zoos were kept in sufficient numbers in different collections, while a further 101% were represented by a single specimen. Only 43% of the amphibian species that were recommended by the Amphibian Ark for ex situ conservation were kept in zoos. Moreover, 44.3% of the globally threatened amphibians in zoos were each held by a single zoo only. With some exceptions, reproduction success of amphibians in zoos was low and reported for only 10% of amphibian species in two or more institutions within one year. In the present study, a richness analysis provided further insights into the focus areas of amphibians in zoological collections. Large numbers of zoos in North America and Europe maintained amphibian collections of global importance, although the distribution of these institutions did not match the natural distribution of target species that were most urgently in need of ex situ rescue. Investing in conservation-breeding programmes and cooperation with local partners will help to increase the number of threatened amphibian taxa in zoos. Although the global zoo community’s response to the amphibian decline is slow, it still holds the capability to procure a shift from common to threatened taxa. By providing their expertise and facilities for the keeping and (conservation) breeding of threatened amphibian taxa, zoos can play a key role in amphibian conservation in terms of the ‘One Plan approach’.
- Klein, B., R. A. Regnet, M. Krings, and D. Rödder. 2020. Larval development and morphology of six Neotropical poison-dart frogs of the genus Ranitomeya (Anura: Dendrobatidae) based on captive-raised specimens. Bonn zoological Bulletin 69 (2): 191–223. (PDF) Abstract
- Larval development is a crucial step during the ontogeny of amphibians, concomitantly it is the most sensitive life phase in this group. Due to the complex morphological, physiological and anatomical changes, in addition to their susceptibility to the environment changes, this phase is known as one of the most critical period of development as well as an obstacle in ex-situ breeding programs. Tadpole growth rates can be used to predict the effects of biotic interactions, as well as to predict the survival rate on environmental changes. The assessment of the mortality rate during this phase can be performed using a non-invasive image-based tool, programmed on the open source statistical platform R, SAISAQ (semi-automatic quantification of image-based surface area). It allows analyzing semi-automatically a sequence of standardized image files in order to quantify growth rates. However, the current literature lacks estimates of the larval growth rates for the most species of amphibians, which is also true for species of the genus Ranitomeya Bauer, 1986. Herein, we present the data of the complete larval development of Ranitomeya amazonica (Schulte, 1999), R. benedicta Brown, Twomey, Pepper & Sanchez-Rodriguez, 2008, R. imitator (Schulte, 1986), R. reticulata (Boulenger, 1884), R. sirensis (Aichinger, 1991) and R. vanzolinii (Myers, 1982), assisted by photographs, drawings and tables with detailed information about the metamorphosis. In addition, we provide a new larval description for R. benedicta. The results presented here also provide new data of the larval development and morphology for the target species, based on a sample series for each species. With this information, we want to contribute to a better understanding of the group and provide important data to help solve the systematic relationships puzzle. Providing also a baseline to improve further research on captive breeding, our results may have important implications for conservation breeding programs.

- Lepidodactylus lugubris is a parthenogenetic gecko which has been increasingly expanding its range during the last century. This invasive species has been reported from multiple tropical and subtropical countries in five continents, most of which were colonized in recent times. In order to understand how the realized niche of the species was affected by this dramatic geographic range expansion, we reconstructed the history of the geographic range expansion. We built models of the realized niche of the species at different points in time during the invasion process. This was achieved through the implementation of modern hypervolume construction methods, based on the Hutchinson’s niche concept. The models were then compared to detect possible realized climatic niche expansion over time. Furthermore, we investigated possible pathways used by the species to spread. A progressive expansion of the realized niche was identified. As the species spread into new areas, we observed a tendency to colonize regions with warmer temperatures and higher precipitation rates. Finally, we found evidence for cargo shipping being the major pathway through which the species expands its range. Further studies on this topic should aim to investigate the role of biological interactions, and how they shape the distribution of L. lugubris on a global scale. A deeper understanding of this kind of processes will help us tackle the issue of invasive species, which has become a major challenge in conservation biology.

- The effects of habitat loss on the distribution of populations are often linked with species specialization degree. Specialist species can be more affected by changes in landscape structure and local patch characteristics compared to generalist species. Moreover, the spatial scale at which different land covers (eg. habitat, cropland, urban areas) affect specialist species can be smaller. Specialization is usually assumed as a constant trait along the distribution range of species. However, for several taxa, there is evidence of higher specialization degree in peripheral populations compared with populations in the core. Hence, peripheral populations should have a higher sensitivity to habitat loss, and strongest effects should be found at a smaller spatial scale. To test these expectations, we implemented a patch-landscape approach at different spatial scales, and compared effects of landscape structure and patch characteristics on occupancy probability among northern peripheral, more specialized populations (Czech Republic) and core populations (Bulgaria) of the eastern green lizard Lacerta viridis. We found that landscape structure and patch characteristics affect differently the occupancy probability of Lacerta viridis in each region. Strongest effects of habitat loss were found at a spatial scale of 150m around patches in the periphery, but at a scale of 500m in the core. In the periphery occupancy probability of populations was principally affected by landscape composition, and the effect of habitat quality was stronger compared to core populations. In the core, persistence of populations was mainly explained by characteristics of the spatial configuration of habitat patches. We discuss possible ecological mechanisms behind the relationship between sensitivity to habitat loss, populations’ specialization degree and position in the distribution range, and suggest conservation measures for L. viridis.

Mitochochondrial DNA variation and Quaternary range dynamics in the endangered Yellow Spotted Mountain Newt, Neurergus derjugini (Caudata, Salamandridae). Journal of Zoological Systematics and Evolutionary Research 57 (3): 580 – 590. (PDF) Abstract
- In temperate regions of the Earth Pleistocene, climatic fluctuations significantly influenced distribution of species. However, little is known on how glacial and interglacial cycles affected range dynamics of the species occupying lower latitudes. In this study, we investigated mitochondrial DNA (mtDNA) variation and reconstructed the potential current and past (during the mid-Holocene, 6 ka BP, and the Last Glacial Maximum, LGM, 21 ka BP) distribution of Neurergus derjugini, an endangered amphibian species endemic to the mid-Zagros Mountains in Iran and Iraq. Six haplotypes identified in the control region (D-loop) form a well-supported monophyletic clade, distinct from other Neurergus species and revealing a sister relationship to Neurergus kaiseri. Nucleotide diversity quantifying mean divergence between the sequences is low and does not support the recognition of distinct evolutionary lineages in Neurergus derjugini. The landscape connectivity analysis and the haplotype parsimony network reveal higher gene flow rate between the breeding streams in the southern part of the range, while the northern populations are more isolated. The potential distribution of Neurergus derjugini is restricted to valleys close to mountain tops, wherein very high elevations and dry habitats appear to be unsuitable. During the mid-Holocene and LGM conditions, the range of the species may have been more extended and shifted to lower elevations. These findings show retraction of the Neurergus derjugini range during the Quaternary and indicate that range dynamics of the species occupying lower latitudes may not follow a scenario of glacial retraction and postglacial expansion.

- Current biodiversity patterns of Neotropical amphibians are the result of their functional and phylogenetic relationships. Understanding the associations between ecological similarity and phylogenetic relatedness among species can provide a convincing statement on the role of evolutionary history in the filling of the niche space. Here, we assessed the ancestral character states of amphibian ecological traits and their evolutionary history in the Atlantic Forest Hotspot. We used 12 genes (11,906 bp) to reconstruct a phylogeny for 207 amphibian species and related it to eight ecological traits regarding their morphology, life-history and behavioural features. We revealed that closely related species can have similar ecological traits, suggesting that these traits are driven by phylogenetic history. Despite the high endemism rate of Atlantic Forest amphibians, our findings heavily rely on good studies on complete amphibian phylogenetic lineages to overcome potential biogeographical constraints. Using mechanisms of adaptive evolution in the context of phylogenetic diversification, we suggest that closely related species have different phylogenetic signals and ecological traits can evolve without relatedness.

- Most of Earth’s biodiversity is found in 36 biodiversity hotspots, yet less than 10% natural intact vegetation remains. We calculated models projecting the future state of most of these hotspots for the year 2050, based on future climatic and agroeconomic pressure. Our models project an increasing demand for agricultural land resulting in the conversion of >50% of remaining natural intact vegetation in about one third of all hotspots, and in 2–6 hotspots resulting from climatic pressure. This confirms that, in the short term, habitat loss is of greater concern than climate change for hotspots and their biodiversity. Hotspots are most severely threatened in tropical Africa and parts of Asia, where demographic pressure and the demand for agricultural land is highest. The speed and magnitude of pristine habitat loss is, according to our models, much greater than previously shown when combining both scenarios on future climatic and agroeconomic pressure.

- We studied the diet of Leptodactylus spixi from a cacao plantation in southern Bahia, Brazil. A total of 109 frogs were manually collected between December 2006 and October 2007 and analysed using a stomach flushing method. Of these, 69 stomachs revealed 168 prey items. Acarina, Orthoptera and Formicidae were the most abundant items, while Orthoptera, Diplopoda and Hemiptera were the most important in terms of frequency of occurrence. With more than 50% of total prey volume and the highest Index of Relative Importance, Orthoptera was considered the dominating prey category for this species in the studied area. The comparison between available potential prey in the environment and diet revealed that L. spixi fed on most present invertebrates. Electivity values were highest for orthopterans, gastropods and dermapterans. We conclude that L. spixi can be considered a “sit-and-wait” predator and also a generalist consuming what is available in the environment.

- In this study, we report on the successful keeping, breeding, and rearing of Klappenbach’s Redbellied Frog, Melanophryniscus klappenbachi Prigioni and Langone, 2000. Breeding and spawning took place after a relatively dry period without using a brumation period. To initiate mating behavior the toads were introduced into a rain chamber with a raised water level and constant irrigation in accordance with the toad’s natural habitat and heavy rainfalls. The fast developing tadpoles started metamorphosis after 19 days at a constant water temperature of 23 °C and pH values between 6.5 and 7.9. A higher pH value led to slightly faster growth irrespective if tadpoles were reared singly or in groups.

- Symbiont-bearing Larger Benthic Foraminifera (LBF) are ubiquitous components of shallow tropical and subtropical environments and contribute substantially to carbonaceous reef and shelf sediments. Climate change is dramatically affecting carbonate producing organisms and threatens the diversity and structural integrity of coral reef ecosystems. Recent invertebrate and vertebrate surveys have identified the Coral Triangle as the planet’s richest center of marine life delineating the region as a top priority for conservation. We compiled and analyzed extensive occurrence records for 68 validly recognized species of LBF from the Indian and Pacifc Ocean, established individual range maps and applied Minimum Convex Polygon (MCP) and Species Distribution Model (SDM) methodologies to create the first ocean-wide species richness maps. SDM output was further used for visualizing latitudinal and longitudinal diversity gradients. Our findings provide strong support for assigning the tropical Central Indo-Pacific as the world’s species-richest marine region with the Central Philippines emerging as the bullseye of LBF diversity. Sea surface temperature and nutrient content were identified as the most influential environmental constraints exerting control over the distribution of LBF. Our findings contribute to the completion of worldwide research on tropical marine biodiversity patterns and the identification of targeting centers for conservation efforts.

- Tadpoles of Polypedates otilophus originating from two different foam nests were raised at water temperatures between 19°C and 27°C. A larval staging table according to Gosner is provided for the first time for the genus. The clutch sizes of the foam nests differed (19 and 49 eggs, respectively), but only 14 and 17 tadpoles hatched at stage 25. The first tadpole of nest one completed metamorphosis after 120 days and the first tadpole of nest two after 131 days. Before metamorphosis is completed, the metamorphs developed significant brown striation which is first visible on the hind legs and subsequently also on the dorsal side of the body. Detailed characteristics of each larval stage are provided. We herein provide the first detailed report on the larval development of P. otilophus, which can be used as surrogate species for captive management of other Polypedates taxa. Most interestingly, the temporal development of larvae in this species appears to be extremely plastic and strongly depending on ambient temperature.

- The occurrence of the Black-fronted Francolin Pternistis atrifrons is restricted to a tiny area in southern Ethiopia. Based on field studies from 2012 to 2014, we modelled the range and estimated the population size of the species in order to evaluate its current conservation status. Annual mean temperature (relatively low) and precipitation (relatively high) proved to be key factors for the probability of its occurrence. The modelled range is 1,286 km2 (“extent of occurrence” according to the IUCN Red List criteria). However, only about one third of the modelled range is actually populated by the Blackfronted Francolin. This area, around 385 km2, corresponds to the IUCN’s “area of occupancy”. The total population size is estimated at 1,100 to 2,100 mature individuals. Thus, we conclude that the species should be classified as Endangered, criteria: A2c+B1ab(i,iii,v) + B2ab(i,iii,v); population trend: decreasing. This means that the Black-fronted Francolin is one of Africa’s most endangered galliforms. Major threats are range and habitat losses due to agricultural expansion, grazing pressure, commercial firewood and timber exploitation, and hunting. Furthermore, expected climate changes in south-east Ethiopia (higher temperatures, less precipitation) could further exacerbate these threats. We propose urgent conservation actions, including the extension of the currently projected Borana National Park.

- Habitat demands and species mobility strongly determine the occurrence of species. Sedentary species with specific habitat requirements are assumed to occur more patchy than mobile habitat generalist species, and thus suffer stronger under habitat fragmentation and habitat deterioration. In this study we measured dispersal and habitat preference of three selected butterfly species using mark-release-recapture technique. We used data on species abundance to calculate Species Distribution Models based on high-resolution aerial photographs taken using RGB / NIR cameras mounted on a UAV. We found that microhabitats for species with specific habitat requirements occur spatially restricted. In contrast, suitable habitats are more interconnected and widespread for mobile habitat generalists. Our models indicate that even managed grassland sites have comparatively little habitat quality, while road verges provide high quality micro-habitats. In addition, dispersal was more restricted for specialist butterfly species, and higher for the two other butterfly species with less ecological specialization. This study shows synergies arising when combining ecological data with high precision aerial pictures and Species Distribution Models, to identify micro-habitats for butterflies. This approach might be suitable to identify and conserve high quality habitats, and to improve nature conservation at the ground.

- Species distribution models estimate the relationship between species occurrences and environmental and spatial characteristics. Herein, we used maximum entropy distribution modelling (MaxEnt) for predicting the potential distribution of the Plateau Snake Skink Ophiomorus nuchalis on the Iranian Plateau, using a small number of occurrence records (i.e. 10) and environmental variables derived from remote sensing. The MaxEnt model had a high success rate according to test AUC scores (0.912). A remotely sensed enhanced vegetation index (39.1%), and precipitation of the driest month (15.4%) were the most important environmental variables that explained the geographical distribution of O. nuchalis. Our results are congruent with previous studies suggesting that suitable habitat of O. nuchalis is limited to the central Iranian Plateau, although mountain ranges in western and eastern Iran might be environmentally suitable but not accessible.

- The available range of habitats and suitable abiotic conditions like temperature and radiation tends to be narrower toward the periphery of the distribution range of species. Peripheral populations of generalist species could then be more specialized and have a smaller and differentiated realized niche (habitat niche in our study) compared to populations at the core. Likewise, patterns of microhabitat selection can differ between periphery and core. In our study, we compared niche size and microhabitat selection among core (Bulgaria) and northern peripheral (Germany, Czech Republic) populations of Lacerta viridis and estimated niche differentiation among regions. We collected data on vegetation structure and abiotic parameters at the microhabitat scale in each region. In order to compare niche size among regions and estimate niche differentiation, we built multidimensional niche hypervolumes. We applied generalized linear mixed models and model averaging, accounting for spatial autocorrelation when necessary, to analyze microhabitat differences among regions and microhabitat selection in each region. Peripheral populations were more specialized, having a smaller niche than core ones, and their niche differed from that in the core (Sørensen overlap in all comparisons.

- Leopard (Panthera pardus) populations are declining worldwide. There are limited data on leopard ecology, especially activity patterns and habitat use, but these are vital to facilitate their conservation. In Zambia we radio tracked two female and three male leopards to study home range sizes, activity patterns and habitat preferences in Luambe National Park (LNP), and an adjacent Game Management Area used for trophy hunting. Home range sizes (MCP 95%) comprised 28.3–55.7 km2 for males and 3.1–42.3 km2 for females; Kernel densities (50%; 95%) were 32.5–80.6 km2 for males and 3.0–23.0 km2 for females. The home range for one female shrank during motherhood. Analysis of habitat use and activity patterns of leopards revealed sex-specific differences. Males showed a higher mobility than females. During 24-h observations all individuals showed a minimum mobility during noon hours and maximum mobility before sunrise and sunset. Analyses of habitat preferences using the Jacob-Index and R package adehabitatHS showed that leopards prefer denser vegetation types and rather avoid grassland. These findings should be taken into account in conservation decisions, for example in the granting of trophy hunting activities.
