Freshwater ecosystems are highly biodiverse¹ and important for livelihoods and economic development², but are under substantial stress³. To date, comprehensive global assessments of extinction risk have not included any speciose groups primarily living in freshwaters. Consequently, data from predominantly terrestrial tetrapods4,5 are used to guide...
An updated list confirms the presence of 134 species of wild mammals in the Western Ghats, India. The superimposed distribution range of all, and threatened species of mammals depicts the potential mammalian key diversity areas for the Western Ghats, which can be prioritized for long-term conservation. These mammalian key diversity areas are confin...
Comprehensive assessments of species’ extinction risks have documented the extinction crisis and underpinned strategies for reducing those risks. Global assessments reveal that, among tetrapods, 40.7% of amphibians, 25.4% of mammals and 13.6% of birds are threatened with extinction. Because global assessments have been lacking, reptiles have been o...

• Freshwater biodiversity is declining at an unprecedented rate. Freshwater conservationists and environmental managers have enough evidence to demonstrate that action must not be delayed but have insufficient evidence to identify those actions that will be most effective in reversing the current trend.
• Here, the focus is on identifying essential...
Some conservation prioritization methods are based on the assumption that conservation needs overwhelm current resources and not all species can be conserved; therefore, a conservation triage scheme (i.e., when the system is overwhelmed, species should be divided into three groups based on likelihood of survival, and efforts should be focused on th...
The COVID-19 pandemic has impacted every sphere of human society. The paradigm shift of focus to COVID-related research and management has significantly affected various scientific domains, including biodiversity conservation. We assessed the perceptions of early-career researchers working for biodiversity conservation across India, to understand t...
Asking authors who have tested interventions to explain how they have placed their paper in context will help ensure conservation science reduces the perils of cherry picking scientific evidence and will improve the design of future work. It will not provide a complete remedy to bias in conservation articles. Ideally, the impact of this measure wil...

Gives a summary account on the Lepus nigricollis
A new species Nyctibatrachus mewasinghi is described from the Malabar Wildlife Sanctuary of Western Ghats of Kozhikode District, Kerala. The new species can be distinguished from known congeners based on small adult size, head equal to or slightly wider than long, less wrinkled dorsal skin with prominent granular projections, absence of dorso-later...
Dahanukar et al. (2016: pp. 9234) made available the genus name Walkerana (ZooBank id: urn:lsid:zoobank.org:act:1A088397-8F05-4339-8696-A50093E88CD5; type species: Ixalus diplostictus Günther, 1876: 574, Pl. 63 fig. C) within the family Ranixalidae for the monophyletic group with reduced webbing endemic to the Western Ghats of India south of the Pa...
Leaping frogs of the family Ranixalidae are endemic to the Western Ghats of India and are currently placed in a single genus, Indirana. Based on specimens collected from their entire range and a comprehensive study of type material defining all known species, we propose a revised taxonomy for the leaping frogs using an integrative approach includin...
These Guidelines are designed to be applicable to the full spectrum of conservation translocations. They are based on principle rather than example. Throughout the Guidelines there are references to accompanying Annexes that give further detail.
Humans depend on biodiversity in myriad ways, yet species are being rapidly lost due to human activities. The ecosystem services approach to conservation tries to establish the value that society derives from the natural world such that the true cost of proposed development actions becomes apparent to decision makers. Species are an integral compon...
Freshwater invertebrates receive relatively little publicity and conservation attention, in spite of their key role in aquatic food webs and ecosystem functioning.
Decapod crustaceans such as caridean shrimps and gecarcinucid freshwater crabs comprise some of the most poorly known aquatic taxa, even in exceptional regions of freshwater biodiversity...
The new genus, Damarchilus gen. nov. is proposed with descriptions of two new species, Damarchilus nigricus sp. nov. and D. rufus sp. nov. from north-east India. External characters for the new genus and new species are examined and illustrated. Also, the natural history of the species is provided.
We investigated the distribution of Batrachochytrium dendrobatidis (Bd) fungal infections in amphibians of the Western Ghats mountain range in India, based on data from 497 samples. Eight individuals were positive, with genomic equivalents ranging from 2 to 785 zoospores. A single widespread Bd strain identical to the haplotype endemic to Asia was...
Reports on the concurrence of mammals in the Meghamalai landscape were collated from published literature and also the data obtained from a recent study spanning over 18 months (June 2011-December 2012). Sixty-three species belonging to 24 families occur in the landscape, which include 24 globally threatened (one Critically Endangered; seven Endang...
The Western Ghats of India harbors a rich diversity of amphibians with more than 77% species endemic to this region. At least 42% of the endemic species are threatened due to several anthropogenic stressors. However, information on amphibian diseases and their impacts on amphibian populations in this region are scarce. We report the occurrence of B...
This is the first attempt to update the list of spiders described formally in India. The list is compiled following Platnick's The World Spider Catalog. Extensive search of scientific peer-reviewed publications in the region revealed 40 new species, which are not included in Platnick's list. The checklist is compared extensively with Tikader's list...
The known distribution range of Poecilotheria striata Pocock, 1895 in India is from Mysuru in the north to Thiruvananthapuram in the south. During the recent surveys in northern Karnataka, P. striata was recorded from six locations in Dandeli and nearby areas in the Uttara Kannada District. With the new records from Uttara Kannada, the distribution...
While the collection of fish for the aquarium pet trade has been flagged as a major threat to wild populations, this link is tenuous for the unregulated wild collection of endemic species because of the lack of quantitative data. In this paper, we examine the extent and magnitude of collection and trade of endemic and threatened freshwater fishes f...
The mygalomorph spiders remain poorly studied in India. So far, 89 species under 27 genera and eight families have been reported from the country. Most of the mygalomorph descriptions from the region were done more than a century ago, based on a few prominent morphological characters. In the last 10 years, interest in mygalomorphs has revived, and...

Assessing Biodiversity Declines
Understanding human impact on biodiversity depends on sound quantitative projection. Pereira et al. (p. 1496 , published online 26 October) review quantitative scenarios that have been developed for four main areas of concern: species extinctions, species abundances and community structure, habitat loss and degradati...
The genus Heligmomerus Simon, 1892 of the trapdoor spider family Idiopidae is represented by a single species, H. prostans Simon, 1892 in India. Idiops biharicus Gravely, 1915 and I. barkudensis Gravely, 1921 were found to be misplaced in the genus Idiops and transfer to the genus Heligmomerus based on a dorsal saddle-shape depression on tibiae III...
A study to understand diversity and changes in non-volant small mammal composition in the Western Ghats of Coorg District, Karnataka was conducted from April 2004 to April 2008. A total of 11060 trap nights of sampling in various habitats such as forest fragments, coffee and cardamom plantations, open areas including grasslands, agricultural fields...
A new species of the genus Sason, S. rameshwaram sp. nov., of the Brush-footed trapdoor spider family Barychelidae is described from Rameshwaram Island, Tamil Nadu, India. Nest structure and habitat are documented.
The genus Diplothele O. Pickard-Cambridge 1890 of the brush-footed spider family Barychelidae is represented in India by a single species, D. walshi O. Pickard-Cambridge 1890. In this paper, we describe two new species: Diplothele gravelyi from Angul and Diplothele tenebrosus from Ganjam, Orissa. We establish a neotype and provide additional charac...
The genus Thrigmopoeus is endemic to the Western Ghats of India, and is so far represented by two species: Thrigmopoeus truculentus Pocock, 1899 and T. insignis Pocock, 1899. The distribution of T. truculentus was considered to be restricted to its type locality until a few populations were identified in other places. In this paper we provide detai...
The Lion-tailed Macaque (Macaca silenus) is a threatened species inhabiting the rainforests of the Western Ghats mountain range in southern India. Once assessed to be less than a thousand individuals remaining in the wild habitats, the population is now estimated to be
between 3000 and 3500 individuals. However, the rainforest habitats of the speci...
The genus Conothele of the trapdoor family Ctenizidae is reported for the first time from India with the description of two new species Conothele varvarti from Similipal Tiger Reserve in Orissa, eastern India and C. vali from Tawang district in Arunachal Pradesh, northeastern India. The genus was previously considered arboreal in habit but the pres...
