Kostin, Valeria A. Komarova, Anton R. Gromov, Mesele Yihune, Adane Tsegaye, Dmitry Y. Alexandrov, Afework Bekele, Josef Bryja, Leonid A. Lavrenchenko
The recently established Chebera Churchura National Park represents a mosaic of savanna and montane evergreen forest. A report on small mammals (2013) showed their relatively high diversity, but species identification was based only on external morphology. We conducted a new field survey and genetic analyses to shed light on diversity and biogeographical affinities of small mammals in this under-explored

The first identification of Tula orthohantavirus in forest dormice (Rodentia: Gliridae) from Iran Mammalia (IF 1.0) Pub Date : 2023-06-12 Ahmad Mahmoudi, Ehsan Mostafavi, Ali Mohammadi, Tahmineh Jalali, Christiane Denys, Violaine Nicolas, Jean-Pierre Hugot, Aude Lalis, Mostafa Salehi-Vaziri
Orthohantaviruses are a group of zoonotic pathogens that can cause severe and potentially fatal syndromes in humans. Although orthohantaviruses have been documented in Iran, little is known about their potential reservoirs in the country. The present study constitutes the first attempt to detect orthohantavirus infections in rodents in Iran. Sampling was performed in the East Azerbaijan province, during

The diet of commensal Crocidura olivieri (Soricomorpha: Soricidae): predation on co-existing invasive Mus musculus suggested by DNA metabarcoding data Mammalia (IF 1.0) Pub Date : 2023-05-25 Maxime Galan, Anaïs Bordes, Philippe Gauthier, Mamadou Kane, Youssoupha Niang, Éric Pierre, Laurent Granjon
Crocidura olivieri is a large-sized shrew species showing a clear trend towards commensalism in West Africa, where it co-occurs and interacts with a number of rodent species in indoor small mammal communities. Among the rodents present is the house mouse Mus musculus, a major invasive species worldwide. We here test the hypothesis that M. musculus could be part of the diet of C. olivieri in a number

The extirpation of medium and large mammal species from the Ehotilé Islands National Park, south-eastern Côte d’Ivoire Mammalia (IF 1.0) Pub Date : 2023-05-24 Diorne Zausa, Elie B. Bogui, Bertin K. Akpatou, Inza Koné
In West Africa, high deforestation rates and poaching have induced dramatic declines of mammal’s populations and local extinctions. Due to their isolation, island species are more vulnerable than mainland species. The premises of that scenario are perceptible in the Ehotilé Islands National Park, south-eastern Côte d’Ivoire, but have not been documented. This study aimed to update the diversity and

Assemblage, relative abundance and activity pattern of wild mammals in the human-dominated landscape of Vansda taluka, Gujarat, India Mammalia (IF 1.0) Pub Date : 2023-05-24 Mohmad Navaz Dahya, Rohit Chaudhary, Alkesh Shah, Aadil Kazi
Conservation of mammals in human-dominated landscapes requires essential information on their ecological aspects. We used camera traps to assess the wild mammal assemblage, their relative abundance, and activity patterns in the human-dominated landscape of Vansda taluka, Gujarat, India. We deployed 80 camera traps in square grids of 2 km2 resulting in an area coverage of 160 km2. To assess the mammal
