The common vole Microtus arvalis (Pallas, 1778) is the most widespread Microtus species. It has two forms - the European arvalis form (2n: 46, NF: 84) and the Asian obscurus form (2n: 46, NF: 72). The present study aimed to clarify the taxonomic status of M. arvalis populations distributed in Eastern Turkey, Europe and Asia by analysing two mitochondrial (CYTB and COX1) and one nuclear (IRBP) markers. Phylogenetic dendrograms (median-joining networks and Bayesian trees) constructed using the mitochondrial markers clearly separated the Anatolian population from the European and Asian populations. Contrarily, any explicit differentiation was not shown in IRBP analyses. …

The Striped Hyaena, Hyaena hyaena, extends its distribution in the north into Turkey, where it has always been rare. In a status assessment conducted by Kasparek et al. in 2004, it was shown that the species is at the brink of extinction. We compiled information from different sources including a press survey and camera trapping in different parts of the country. The situation has even deteriorated since then. The population has strongly decreased, in particular, in the Marmara and Mediterranean regions, and presently the species survives in Western Anatolia only in some small relict populations in Manisa, İzmir, Muğla, and …
