The present status, distribution, demography, and diet of the Dahl’s Jird

Abstract

Meriones dahli (Shidlovsky, 1962) was previously accepted to be a subspecies of M. meridianus (Pallas, 1773). However, it was later suggested that they are geographically isolated from each other. Although hybridological studies and differences in certain external characteristics support the idea that M. dahli is a separate species, there are still doubts on its species status, and the exact range of its distribution is not known. In this paper, we provide some taxonomic information about the species, and compare these with the information given in previous studies. We argue that some differences exist among Armenian population regarding external measurements. Recent studies indicate that M. dahli is currently only distributed in Turkey, as an endemic mammal species. We provide predictions about the distribution of M. dahli, and report the estimated population size to its maximum value. Food preference studies for this species, conducted under laboratory conditions, are also introduced for the first time. We discuss the ecological data obtained from field studies, and emphasize that the habitat of M. dahli is about to disappear. Consequently, the protection status of this species should urgently be changed to the CR category and conservation studies must be carried out immediately. © 2022, Instituto Internacional de Ecologia.
