Abstract:
In May and October 2017, we assessed the distribution and diversity of herpetofauna in the Ghandruk region of the Annapurna Conservation Area. Using the Visual Encounter Survey (VES) protocol on 11 randomly selected transects, we recorded 662 individuals of 25 herpetofaunal species (12 amphibians and 13 reptiles). Species richness and abundance declined with increases in elevation but only the correlation between elevation and abundance was significant. Neither amphibians nor reptil… Show more
“…3). Another possibility relies on the fact that reptile abundances seem to decline with elevation (Fauth et al 1989, McCain and Sanders 2010, Gautam et al 2020), which could make difficult the collecting and studying of highland reptiles, and consequently limit investigations relying on large sample sizes.…”
More than two million species have been described so far, but our knowledge on most taxa remains scarce or inexistent, and the available biodiversity data is often taxonomically, phylogenetically and spatially biased. Unevenness in research effort across species or regions can interact with data biases and compromise our ability to properly study and conserve biodiversity. Herein, we assess the influence of biological, conservation, geographic and socioeconomic correlates of reptile research effort globally and across six biogeographic realms. We combine bibliometric data from the Scopus database with trait-based approaches and provide research effort information for 10 531 reptile species, modelling it as a function of 10 putative correlates of species-level variation in research effort through negative binomial generalised mixed effect models. We show that reptile research effort is highly skewed toward certain taxa and regions, such as turtles, crocodiles, tuatara, viperids, pythons and some anguimorph lizards, as well as for temperate compared to tropical regions. Our findings indicate that greater research attention is directed towards large-sized and early described reptile species, particularly those whose geographic range overlap with biodiversity institutions. Although we demonstrate that biological and socioeconomic factors more strongly affect reptile research effort variation, geography and conservation-related factors also matter. Global patterns are mostly consistent, but variation across realms were observed and likely reflects differences in socioeconomic attributes as well as in the amount of species to be studied in each realm. Directing researchers and citizen scientists' attention toward understudied taxa will contribute to alleviate this biased biodiversity knowledge, although the sheer amount of species in tropical regions inevitably makes it a long-term solution. Performing comparative studies across species with similar levels of research attention could represent a more immediate and feasible alternative.

“…Dubois (1974) reported it as Rana assamensis in Khasi hills of the Indian state of Meghalaya and in Sikkim as Rana (Paa) sikimensis. In addition, Ombrana sikimensis is also found near freshwater streams in Nepal-Himalayas (Schleich and Kästle, 2002;Shrestha and Gurung, 2019;Gautam et al, 2020). This specimen of Ombrana sikimensis was found in spring (May, 2020) (Fig.…”

We report the discovery of the Sikkim Frog, Ombrana sikimensis from Central Bhutan's Zhemgang district, in the Himalayan Kingdom of Bhutan. The frog which was found residing in a clean perennial stream is used by the local human population for consumption. It is supposed to heal stomach related ailments. This record will help Bhutan understand the use and importance of the species and help in prioritizing conservation.
“…The region is bordered by the dry alpine deserts of Mustang and Tibet (China) in the north, valleys and northern foothills of Pokhara in the south, the Kali Gandaki River in the west, by Marsyandi Valley to east. This conservation area harbors 1,226 floral species, 105 mammals, 518 birds, 40 reptiles and 23 amphibians (Gautam et al 2020, Khakurel et al 2020. Along with rich biological diversity, ACA also presents splendid cultural diversity.…”

Background: Nepal is considered as a biodiversity hotspot with a multi-dimensional social system accompanied by vast amounts of plants and traditional knowledge regarding ethnobotanical practices. There are number of ethnic groups in Nepal whose culture is enriched by ethnobotanical knowledge that has been passed down over generations. Also, ethnobotanical knowledge is diverse in different regions of Nepal. The ethnobotany of Nepal and related archaic knowledge are of great importance to the advancement of local, national and global human society. In this study, we analyze ethnobotany in five districts within Annnapurna Conservation Area, Nepal's largest protected area.Methods: Information was extracted from relevant publications from the year 1995 to 2021 from electronic databases following the PRISMA framework. Those extracted data from thirty-two publications were analyzed systematically.Results: This study revealed that the temporal research trend has varied significantly and that the number of research in the accessible areas were relatively higher. Despite the high occurrence of research focusing on ethnomedicinal uses, other ethnobotanical research focusing on Non-timber forest products, wild edible foods are still lacking.Conclusions: Priority should be given to relatively unexplored research topics and lesser explored areas such as wild edible foods and non-timber forest products, and pharmacognosy in the future, so that the research gap will be addressed which ultimately brings out the real potentiality of the ethnobotanical sector of Annapurna Conservation Area.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
