“…We undertook a systematic review using the search, appraisal, synthesis and analysis (SALSA) approach (Grant & Booth, 2009).

Population size and geographical range are the key quantitative criteria used by the IUCN to assess the conservation status of a species. However, such information is often incomplete and inconsistent, even for seemingly abundant species. To assess the population and conservation status of Indian primates, we conducted a systematic review of recent research using the searching, appraisal, synthesis and analysis (SALSA) approach. We reviewed a total of 41 studies on Indian primates conducted during the last 2 decades (2000–2021) for information on various parameters that influence their conservation. We found that 20 out of a total of 26 primate species were evaluated for their population status, and the majority of these studies (71%) showed an overall declining population trend. Remarkably, all but one of the studies conducted exclusively within protected areas revealed declining population trends, whereas trends were more variable for primate populations in non-protected areas. Our data indicate that only 27% (n = 7) of Indian primate species have been surveyed or re-surveyed to assess their population status within the last 5 years. Although threats vary in time and space from species to species, 78% of the studies recorded natural system modifications including habitat loss and fragmentation among the main threats to the survival of Indian primates. Most studies on the population status of Indian primates have either been spatially limited or used outdated methods. We recommend that future studies adopt robust techniques to estimate populations and work across larger geographical scales to develop effective management strategies for the conservation of primates in India.

The genus Soriculus is currently recognized as monotypic, containing only one species, Soriculus nigrescens, which is distributed mainly in the Himalayas and the southern Hengduan Mountains. The taxonomy of Soriculus is ambiguous due to insufficient taxonomic sampling. We conducted extensive surveys of Soriculus across the Himalayas and Hengduan Mountains. We sequenced two mitochondrial and three nuclear genes, and the complete mitochondrial genomes of several selected specimens to infer the phylogenetic relationships of Soriculus and also analysed their morphological and morphometric variations. Our results indicate monophyly of Soriculus, and the diversity of the genus is greatly underestimated. We described two new species, Soriculus nivatus sp. nov. and Soriculus medogensis sp. nov., and elevated S. minor as a distinct species. Additionally, we found another putative new species of Soriculus in Medog County; however, we did not formally describe it because only one specimen was collected. Divergence time estimates suggest that the global cooling and desiccating events around the Miocene/Pliocene and Pliocene/Pleistocene boundaries and the Pleistocene climatic oscillations may have played major roles in the diversification of Soriculus. Our results highlight the overlooked diversity of small mammals in the eastern Himalayas, which warrants further surveys and taxonomic studies.

The North African sengi (Petrosaltator rozeti syn. Elephantulus rozeti) is a small mammal endemic to the Maghreb area, and is one of the least studied mammals in North Africa. Little is known about its status, habitat preference, and distribution across large areas of its range. This work provides a detailed geographical and ecological distribution of the species in Tunisia based on 200 surveyed sites throughout the country with 103 positive occurrence records. We also used species distribution modelling to assess the habitat suitability of the species. P. rozeti showed a heterogeneous bioclimatic niche, with a presence in the semi-arid, arid and Saharan bioclimatic zones. But the species’ distribution seems to be limited to the main mountain ranges of Tunisia. This was also confirmed by habitat suitability modeling where the elevation was the most informative predictor variable. Our work also show some first recorded ecological traits, confirms the rock-dwelling specialist nature of the species and debate its endemism to mountain ecosystems.
