A disease caused by the fungi Batrachochytrium dendrobatidis（Bd） and Batrachochytrium salamandrivorans（Bsal） is responsible for recent worldwide declines and extinctions of amphibian populations.The Qinghai-Tibetan Plateau（QTP） is aglobal biodiversity hotspot,yet little is known about the prevalence of Bd and Bsal in this region.In this study,we collected 336 non-invasive skin swabs from wild amphibians（including an exotic amphibian species） on the QTP.In addition,to assess the historical prevalence of Bd and Bsal on the QTP,we collected 117 non-invasive skin swabs from museum-archived amphibian samples（from 1964-1982） originating from the QTP.Our results showed all samples to be negative for Bd and Bsal.The government should ban the potentially harmful introduction of non-native amphibian species to the QTP and educate the public about the impacts of releasing exotic amphibians from chytridinfected areas into native environments of the QTP.

Understanding the genetic mechanisms underlying particular adaptations/phenotypes of organisms is one of the core issues of evolutionary biology.The use of genomic data has greatly advanced our understandings on this issue,as well as other aspects of evolutionary biology,including molecular adaptation,speciation,and even conservation of endangered species.Despite the well-recognized advantages,usages of genomic data are still limited to non-mammal vertebrate groups,partly due to the difficulties in assembling large or highly heterozygous genomes.Although this is particularly the case for amphibians,nonetheless,several comparative and population genomic analyses have shed lights into the speciation and adaptation processes of amphibians in a complex landscape,giving a promising hope for a wider application of genomics in the previously believed challenging groups of organisms.At the same time,these pioneer studies also allow us to realize numerous challenges in studying the molecular adaptations and/or phenotypic evolutionary mechanisms of amphibians.In this review,we first summarize the recent progresses in the study of adaptive evolution of amphibians based on genomic data,and then we give perspectives regarding how to effectively identify key pathways underlying the evolution of complex traits in the genomic era,as well as directions for future research.

We report amphibian and reptile distribution records based on recent biodiversity surveys conducted at the Angat Watershed Reservation, Bulacan Province, Luzon Island, Philippines. This watershed constitutes the principal water source for Manila, the Philippines＇ largest metropolitan area. As virtually nothing is known of the herpetological diversity of the immediate area and the surrounding Bulacan Province, all species recorded as part of our surveys constitute major geographical records and/or significant range extensions. Our data result in a total of 63 new records of amphibian （19 frogs） and reptile （22 lizards, 2 turtles, and 20 snakes） species for this protected area （and immediate vicinity） that serves as a watershed for the major metropolitan area of Manila and surrounding cities. Together with the few previous literature records, our new records bring the total number of amphibian and reptile species for Bulacan Province to 68. We discuss several strategies for future survey work （focusing on habitat type, seasonal variation, and elevational variability） that we anticipate will result in increased knowledge of diversity within the Angat Watershed Reserve. The impressive level of herpetological diversity within such a small area, so close to Metro Manila, emphasizes that the diversity and distribution patterns of amphibians and reptiles from Luzon are still poorly known and in need of further study.

Studies in recent years have shown that aquatic pollution by microplastics(MPs)can be considered to pose additional stress to amphibian populations.However,our knowledge of how MPs affect amphibians is very rudimentary,and even more limited is our understanding of their effects in combination with other emerging pollutants.Thus,we aimed to evaluate the possible toxicity of polyethylene MPs(PE-MPs)(alone or in combination with a mix of pollutants)on the health of Physalaemus cuvieri tadpoles.After 30 days of exposure,multiple biomarkers were measured,including morphological,biometric,and developmental indices,behavioral parameters,mutagenicity,cytotoxicity,antioxidant and cholinesterase responses,as well as the uptake and accumulation of PE-MPs in animals.Based on the results,there was no significant change in any of the parameters measured in tadpoles exposed to treatments,but induced stress was observed in tadpoles exposed to PE-MPs combined with themixture of pollutants,reflecting significant changes in physiological and biochemical responses.Through principal component analysis(PCA)and integrated biomarker response(IBR)assessment,effects induced by pollutants in each test group were distinguished,confirming that the exposure of P.cuvieri tadpoles to the PE-MPs in combination with a mix of emerging pollutants induces an enhanced stress response,although the uptake and accumulation of PE-MPs in these animalswas reduced.Thus,our study provides newinsight into the danger to amphibians of MPs coexisting with other pollutants in aquatic environments.

Sexual dimorphism between males and females is a common pattern observed in the natural world and has become one of the main focuses of evolutionary biology.Amphibian head size and shape are important factors that may influence food acquisition,but knowledge about the sexual differences between amphibian head size and shape is relatively scant.Here,intersexual differences in the head size and shape of Rana kukunoris,which is a high-elevation frog from the Qinghai-Tibet Plateau,were investigated.Significant differences were found in the head shape but not the head size between sexes.A significant correlation was also observed between prey size and head size.However,these correlations disappeared when individual body size was controlled,suggesting that body size but not food size was the main factor resulting in intersexual differences in head size/shape.The results suggested that food competition between sexes did not result in sexual dimorphism of head shape among these frogs.

Fire is a natural agent with a paramount role in ecosystem functioning and biodiversity maintenance.Still,it can also act as a negative force against many ecosystems.Despite some knowledge of the interactions of fire and vegetation,there is no clear understanding of how different components of fire regimes(i.e.,severity,history,or frequency)influence known patterns of animal communities.Therefore,we performed a systematic review on the global responses of arthropods,birds,mammals,reptiles,and amphibians to different fire regimes.Specifically,we focused on assessing how fire severity,history,and frequency modulate the effect of fire on the richness and abundance of faunal communities.We conducted a systematic review of 566 papers retrieved from the Scopus database.We also scrutinized all the documents included in the meta‑analysis of Pastro et al.(Pastro et al.Glob Ecol Biogeogr 23:1146–1156,2014).Our selection criteria excluded studies without data on species richness or abundance.We also excluded studies without adequate controls and those without information about the fire regime of the study zone.After careful examination,we used data from 162 studies to perform a quantitative meta‑analysis.From the 162 studies meeting our selection criteria,nearly 60%of the studies are from North America,25%from Australia,11%from Europe,and 4%from the tropics.According to the ecological role of fire,90%of the studies were carried out in fire‑dependent ecosystems(i.e.,conifer forests,natural savannas,pastures).Finally,40%of the studies analyzed birds,22%mammals,and 20%arthropods.The meta‑analysis of the available evidence indicates that fire history is an important modulator of animal richness and abundance.Whether negative or positive,animal responses depended on the time since the last fire event.Considering that short‑term studies may not capture such a long‑term effect on fauna,this translates to more challenges at implementing fire management strategies.Whether or not we can anticipate the impact of the fire will then dep

The conservation status of all the amphibians in China is analyzed,and the country is shown to be a global priority for conservation in comparison to many other countries of the world.Three Chinese regions are particularly rich in amphibian diversity:Hengduan,Nanling,and Wuyi mountains.Sala-manders are more threatened than frogs and toads.Several smaller families show a high propensity to become seriously threatened:Bombinatoridae,Cryptobranchidae,Hynobiidae and Salamandridae.Like other parts of the world,stream-breeding,high-elevation forest amphibians have a much higher likeli-hood of being seriously threatened.Habitat loss,pollution,and over-harvesting are the most serious threats to Chinese amphibians.Over-harvesting is a less pervasive threat than habitat loss,but it is more likely to drive a species into rapid decline.Five conservation challenges are mentioned with recommendations for the highest priority research and conservation actions.

Identifying the origins of alien species has important implications for effectively controlling the spread of alien species. The black-spotted frog , originally from East Asia, has become an alien species on the Tibetan Plateau (TP). In this study, we collected 300 individuals of from 13 native regions and 2 invasive regions (including Nyingchi and Lhasa) on the TP. To identify the source region of the TP introductions, we sequenced portions of the mitochondrial gene. We sequenced a ∼600-bp portion of the mitochondrial gene to identify 69 haplotypes (124 polymorphic sites) in all sampled populations. According to the network results, we suggest that the found on the TP was most likely originated from Chongqing by human introduction. Furthermore, we found that the genetic diversity was significantly lower for invasive than for native sites due to founder effects. Our study provides genetic evidence that this alien species invaded the cold environment of high elevations and expanded the distribution of in China.
