Abstract Populations see their range fluctuate in relation to environmental variations, including climate change, and survival is linked the maintenance of large enough populations broad distributions during these variations. Most amphibian are threatened by numerous ecological anthropogenic variables acting synergy with change. Accumulating basic data such as enables development population dynamics, themselves resulting on adequate conservation plans. Karsenia koreana only known Asian...
While comparatively few amphibian species have been described on the North East Asian mainland in last decades, several subject of taxonomical debates relation to Yellow sea. Here, we sampled Dryophytes sp. treefrogs from Republic Korea, Democratic People's Korea and China clarify status this clade around sea determine impact level change treefrogs' phylogenetic relationships. Based genetics, call properties, adult morphology, tadpole morphology niche modelling, determined segregated D....
AbstractIn species that provide parental care, parents will sometimes cannibalize their own young (i.e., filial cannibalism). Here, we quantified the frequency of whole-clutch cannibalism in a giant salamander (eastern hellbender; Cryptobranchus alleganiensis) has experienced precipitous population declines with unknown causes. We used underwater artificial nesting shelters deployed across gradient upstream forest cover to assess fates 182 nests at 10 sites over 8 years. found strong...
Eastern Hellbenders (Cryptobranchus alleganiensis alleganiensis) are giant, charismatic salamanders of conservation concern. Despite growing interest in their breeding behavior, significant gaps remain our understanding hellbender reproduction, particularly the behavior occurring immediately prior to and during because these activities typically occur within nesting cavity out view. In this study, we used custom-built infrared cameras installed underwater artificial shelters record...
Roadkills are a major threat to the wildlife in human-modified landscapes. Due their ecology, relatively small size, and slow movement, amphibians reptiles particularly prone roadkill. While standardized roadkill surveys provide valuable data for regional trends, such often resource-intensive have limited geographic coverage. Herein, we analyzed dataset of Korean herpetofauna derived from citizen science database iNaturalist compared overall trends detected with survey-based literature data....
The rapid environmental changes associated with the Anthropocene mean that flexible behavioral responses may be a critical determinant of animals' resiliency to anthropogenic disturbance, particularly for species long generation times and low vagility. One type behavior exemplifies this potentially important flexibility is parental care. Eggs juvenile animals are sensitive stressors, ability parents adjust care behaviors buffer their offspring from rapidly changing conditions successful...
Abstract We describe a Raspberry Pi‐based camera system that is portable, robust and weatherproof, with close‐up focus (2.5 cm). show this can be used in remote locations high rainfall humidity. The has an Infrared LED light to film dark places continuously record up 21 days (504 h). also how make concrete artificial shelters mount the in. One of great strengths shelter/camera set‐up animals choose take residence then filmed for extended periods no disturbance. Furthermore, we give examples...
Proper taxonomic and phylogeographic frameworks are a prerequisite in evolutionary, ecological, conservation research, but many species still lack adequate assessments. Earlier studies on the northeast Asian treefrog, Dryophytes japonicus , identified deep Mio-Pliocene diversification; however, phenotypic assessments were lacking, identity of clades is under debate. In this study, we assessed genetic, genomic, morphological, acoustic diversity differentiation within D. complex to propose...
The emergence and spread of infectious diseases is a significant contributor to global amphibian declines, requiring increased surveillance research. We assessed host-vector-parasite dynamics using population eastern hellbender salamanders (Cryptobranchus alleganiensis) that harbor leeches (Placobdella appalachiensis) transmit endoparasitic blood parasites (Trypanosoma spp) the host, with coinfection frequently occurring. centered our study on adult males throughout their extended 8-month...
Biodiversity is declining worldwide with habitat loss and climate change being among the main threats. While it easy to quantify loss, impacts of are less obvious. It therefore important understand species use breeding phenology before a significant shift results in knowledge. Here, we determined for all Korean amphibian based on citizen science (8,763 observations), collected between 1997–2020. We found seasons as defined them be generally shorter than described literature despite large...
In the Republic of Korea, one biggest threats to amphibians is habitat modification such as urbanisation and land conversion. With loss natural habitats, rice paddies play an important role substitute habitats for that originally inhabited wetlands. However, since 70's, traditional agriculture has been modernised, leading increase in number concrete ditches roads bordering paddies. This modernisation could have affected distribution density amphibians. this study, we investigated preferred...
Recently, artificial shelters have been proposed as a novel tool to monitor Hellbenders (Cryptobranchus alleganiensis) and other cryptobranchid salamanders. Factors that influence shelter use by not identified, but are important for maximizing the utility of these monitoring tools. To identify factors, in 2013–2018 we deployed 438 across 10 stream reaches inhabited Hellbenders, within three rivers upper Tennessee River Basin. We hypothesized occupancy nesting would depend on placement, be...
The Japanese giant salamander, Andrias japonicus , is an iconic but declining species of aquatic amphibian. A population within the Nawa River Basin Tottori Prefecture persists faces two significant threats. first major threat waterway obstructions, in form dams, weirs, and concrete embankments, which severely fragment degrade habitat. second water pollution, primarily caused by runoff from animal farms. Both threats to A. can be mitigated with proper actions. We provide science-based...
AbstractVector-borne blood parasites cause myriad sublethal effects and can even be deadly to endotherms, but far less is known about their impacts on ectothermic hosts. Moreover, the pathologies documented in endotherms are generally linked infection by rather than vectors. Here, we measured hematocrit, hemoglobin, relative proportions of immature red cells evaluate physiological two blood-feeding coinfection hosts, differentiating among pathological responses, extrinsic factors, natural...
Abstract Artificial shelters show considerable promise as tools for studying imperiled hellbender salamanders. Their full utility has not yet been fully reached in practice, however, because during initial trials often became blocked by sediment or dislodged high stream discharge events. To determine whether these challenges could be overcome, we deployed 438 artificial of two different designs across 10 reaches and three rivers the upper Tennessee River Drainage 2013–2018. We recorded...
Australia’s native baobab, Adansonia gregorii (F.Muell., Malvaceae: Bombacoideae) is the only baobab outside African continent. Baobabs of continent have shades either red, orange and yellow coloured flowers are pollinated by insects, especially hawkmoths Sphingidae family, or white small mammals (e.g. bats lemurs). In contrast, Australian with white, erected flowers, was found to be mostly hawkmoths. It possible that for this white-flowered species, play a role in pollination. Therefore,...
The endemic Philippine crocodile (Crocodylus mindorensis) is a relatively small, critically endangered freshwater crocodile. In head start program, hatchlings are caught in the wild, reared captivity, and released back into wild after two years. current study aimed to determine optimal rearing strategies of hatchlings, including identification possible diseases during rearing, studying effect ages on natural antibody (NAb) levels. Thirty crocodiles were divided groups, half with hiding...
Abstract The environment that animals experience during development shapes phenotypic expression. In birds, two important aspects of the early‐developmental are lay‐order sequence and incubation. Later‐laid eggs tend to produce weaker offspring, sometimes with compensatory mechanisms accelerate their growth rate catch‐up siblings. Further, small decreases in incubation temperature slow down embryonic rates lead wide‐ranging negative effects on many posthatch traits. Recently, telomeres,...
Pathogenic water molds have a significant impact on many species, especially amphibians. The genus Saprolegnia is pathogenic oomycete restricted to aquatic and moist habitats, its presence strongly linked the abundance of amphibians fishes. We investigated influence egg mortality occurrence under varying environmental conditions in Asiatic toad Bufo gargarizans at 27 breeding sites Republic Korea. then assessed B. surveyed weekly during season for 3 consecutive years. used molecular tools...
