“…(Image 5a-i). Ignorance or lack of awareness of the role of amphibians in biodiversity sustainability, as biological indicators of climate change, pollution, and the benefits of amphibians as pest control agents have led and Spotted Forest Skink S. maculatus are also reported (Decemson et al 2021b;Lalremsanga 2022;Siammawii et al 2022).…”

“…Nestled in the eastern Himalayan region, the northeastern states of India are located at the crossroads of two biodiversity hotspots of the world, i.e., the Eastern Himalaya and the Indo-Burma biodiversity hotspot (Saikia & Kharkongor 2017). The forests of Mizoram are mainly tropical forests with high species richness and endemicity (Lalremsanga 2018). Recent studies from Mizoram have reported several new species to the state that include Amolopsindo burmanensis, Limnonectes khasianus, Microhyla mukhlesuri, and M. mymensinghensis.…”

“…Reptiles like Cyrtodactylus montanus (Muansanga et al 2020), and Gekko lionotum (now Gekko mizoramensis) are some other records. However, with rising incidences of forest fire, shifting cultivation, change in land use, land cover pattern, local consumption, and ethnomedicinal usage, the herpetofauna diversity of the state is in peril (Pawar et al 2004;Lalremsanga 2018;Gouda et al 2021). As the pressure on herpetofauna in the region continues to mount, threat assessments and inventory studies are of great importance to document and conserve the rich herpetological diversity of the state.…”

Herpetofauna is an important group of vertebrates with key functions in ecosystem sustenance. Nonetheless, with ever-increasing anthropogenic activities and lack of evidence-based studies, about 80% of the herpetofauna diversity of southern Asian region is threatened. Our study reports 80 herpetofauna species distributed across different habitat types in Dampa Tiger Reserve (DTR), Mizoram. We revise the amphibian list of DTR throughthe addition of seven species and establish the identity of cryptic species such as Microhyla ornata which is actually two distinct species,i.e., M. mukhlesuri and M. mymensinghensis. Through the questionnaire survey, it was found that 90% of the respondents depended on varied forms of forest resources. Herpetofaunal species account for 30% of the faunal resources with Varanus bengalensis, Ophiophagus hannah, and Python bivittatus being the most consumed reptile species. All chelonians and some amphibians like Duttaphrynus melanostictus, Pterorana khare, Hoplobatrachus tigerinus, Hoplobatrachus litoralis, Hydrophylax leptoglossa, Minervarya asmati, Polypedates teraiensis, and Sylvirana lacrima were also found to be consumed and used for their presumed medicinal values. In addition to hunting, road-kills, use of chemical pesticides, and habitat alteration were recorded to be the prominent threats in the region. The land use and land cover (LULC) data shows a steady recovery of dense forest and a better forest fire scenario as over 90% of the DTR core region falls in the ‘low severity’ and ‘unburned’ category. With continuous alteration in forested areas, the present study will not only provide a fundamental baseline for the conservation of herpetofauna and better management of protected areas but also stimulate future herpetological-based research.

“…Among the four habitats, abnormalities were highest in the coffee plantations, followed by agricultural fields, then bod- ies of water, and forests. Other reports of anophthalmia in Indian anurans include Asian Toads (Duttaphrynus melanostictus) from Nagpur, Maharashtra (Hippargi et al 2010), and the Similipal Biosphere Reserve, Odisha (Ashaharraza and Mahapatra 2020); a Sreeni's Golden Frog (Indosylvirana sreeni) in the southern Eastern Ghats (Ganesh and Arumugam 2015); a critically endangered Amboli Toad (Xanthophryne tigerina) from Amboli, Western Ghats (Pardeshi 2017); a Marbled Globular Frog (Uperodon systoma) (Regmi et al (2021) from agricultural fields in Vadusan Village, Gujarat; and a Greater Stream Horned Frog (Xenophrys major) from Tamdil National Wetland, Mizoram, the only record so far documented from the northeastern states (Lalremsanga 2022).…”

Currently, 41% of amphibian species are threatened with extinction, leading to the ongoing amphibian crisis. In Myanmar, the amphibian diversity is still poorly understood, and, as a result, many conservation gaps remain. To increase the knowledge about Myanmar's amphibians and thus provide an opportunity to fill the gaps in conservation in the country, we assess the species in greater detail. To do so, we compile a species list of the amphibians of Myanmar through various sources and evaluate their threat status using the IUCN Red list. We perform richness analyses to compare the distribution areas of the amphibian species of Myanmar to the distribution of the protected areas (PAs) in the country. We evaluate the representation of Myanmar's amphibians in zoos worldwide through the Zoological Information Management System (ZIMS) to check the implementation of the One Plan Approach to Conservation. Our results suggest that there are 152 amphibian species extant in Myanmar, of which 25 are endemic to the country. 4.6% (n = 7) of all species are classified as threatened, but counting those with insufficient available data as possibly threatened increases the number to 44.1% (n = 67). Of them, 40 species are not covered by any of Myanmar's PAs. That includes 28.6% of the threatened, 35.7% of the potentially threatened, and 48% of the endemic species. According to the ZIMS database, none of Myanmar's threatened, potentially threatened, or endemic amphibian species are kept in any zoo or aquarium worldwide, suggesting that the One Plan Approach is not sufficiently implemented as a conservation measure for Myanmar's amphibians. With this study, we show conspicuous gaps in the protection of Myanmar's amphibians and provide a list of the 36 most threatened species, recommending a possible prioritization for upcoming conservation actions.
