Abstract
Nepal is a global biodiversity hotspot, supporting 213 mammal species with diverse habitats across various landscape types, from the lowland Terai to the high Himalayas. Studies of Nepal’s mammalian fauna are not evenly distributed and better understanding of past biases towards some species, research themes and locations can provide better strategic direction for future research investments. Therefore, we reviewed 575 scientific articles on mammals in Nepal, published between 2000 and 2019 and compiled these in March 2020, to examine trends, patterns and gaps, and pave future plans for mammalian research in Nepal. A positive increase in the number of publications (β = 0.27 ± 0.02SD, P < 0.00) was observed, with a more than threefold increase between 2010 and 2019 compared to 2000–2009 (t = − 6.26, df = 12.21, P < 0.000). Analysis of these documents revealed that mammalian researches favored large flagship, threatened species of carnivores inside Nepal’s protected area system. Geographically, mammalian research was not uniform in Nepal, as most studies were concentrated in Bagmati Province and in the Terai and Chure region. Baseline surveys and ecological studies were more common types of research, while studies on the impact of climate change and wildlife trade and poaching, are scant, which deserves a future look. While these studies shape current mammalogy in Nepal, studies of small, uncharismatic species, and in areas outside protected areas and other provinces except Bagmati, Lumbini and Province One are severely lacking. The research identified habitat loss, degradation and human-wildlife conflict as the major threats to the survival of mammalian species in Nepal. Therefore, redesigning and strict implementation of policies based on habitat management and human-wildlife co-existence, including other threat mitigation measures, are warranted. To address knowledge gaps, the prioritization of future research and funding should be focused on relatively unexplored research themes and under-researched provinces. This approach will help to re-align the research focus with the current need, and assist to fully understand and effectively conserve the wealth of mammalian diversity that Nepal holds.
