The karyotypes of three species of social voles recently discovered in Turkey (Microtus irani karamani, M. schidlovskii, and M. anatolicus) were investigated. All specimens examined revealed similar karyotypes comprising 60 chromosomes in the diploid complement. All autosomes and the X chromosome were acrocentric. The subtelocentric Y chromosome was recorded in M. anatolicus but it was acrocentric in the other species. Dark C-bands were observed in centromeric/pericentromeric areas of all the acrocentric autosomes. The X chromosome had a centromeric C-positive area and the Y chromosome was completely heterochromatic in all specimens examined. AgNORs were recorded in the pericentromeric region of seven autosome pairs in M. irani karamani, ten autosome pairs in M. schidlovskii, and eight autosome pairs of M. anatolicus. Differences in the NOR distribution between the species were quantified in a neighbor-joining tree. The individuals of M. anatolicus appeared as the basal branch in relation to the derived sister group of M. schidlovskii and M. irani karamani.
The variation pattern of the C-heterochromatin and nucleolar organizer region (nOr) distribution, both between and within two cytotypes of M. arvalis with 46 chromosomes, are described. The positive C-bands were observed on six or seven small bi-armed autosomal pairs and in two, three or four acrocentric autosomal pairs. Only a small dark C-band was observed in the acrocentric homologue from a large heteromorphic autosomal pair in the complement of specimens belonging to the obscurus cytotype. The nucleolar organizer region was localized in the secondary constrictions in three autosomal pair in the specimens of the obscurus cytotype. These results may contribute to the knowledge of cytogenetic differentiation between the cytotypes and investigation of their systematic status
Cytogenetic analyses were performed in six specimens of D. laniger and D. nitedula caught with live traps from three Turkish populations. The number of specimens analyzed
The chromosome banding pattern (C-banding, AgNOR staining) was studied in isolated populations of two species of rodents from Turkey, Glis glis and Myodes glareolus. A single nucleolar organizer region was localized in an autosomal pair in the complement of G. glis. Centromeric C-heterochromatin blocks and seven pairs of NOR-bearing autosomes were observed in the complement of M. glareolus. A metacentric Y chromosome was found in the M. glareolus males examined. The detailed structure of karyotypes and the banding patterns differ from some previously published results.
Pellet analyses were used to identify small mammal species in the diet of this owl species in order to reveal its ecological role. In this study, 706 pellets of Asio otus were collected from 3 different localities in Fatih Natural Park between February and March 2014. Pellets were dissolved by using 3% NaOH solution and then bones were dehydrated and identified. The aim of this study was to determine mammal composition in the diet of Asio otus inhabiting Fatih Natural Park of Yozgat Province, Turkey. Residues of bone from 1293 individuals/preys corresponding to 42377.41 g biomass in total were detected as the result of analysis. These individuals were identified to belonging to 12 mammal species (Crocidura suaveolens, Suncus etruscus, Microtus hartingi/lydius, Microtus levis, Microtus sp., Cricetulus migratorius, Mesocricetus brandti, Apodemus sp., Apodemus sylvaticus, Apodemus witherbyi, Mus macedonicus, and Meriones tristrami) from 3 families and 8 genera. Microtus hartingi/lydius, which is known as agricultural pest, was dominant in the diet of Asio otus. When diversity of mammal species within the food composition was examined, Asio otus nesting in forest was found to primarily prefer agricultural and steppe areas, and was also found in woody and bushy areas. The use of Asio otus can be taken into consideration when dealing with rodent species known as agricultural pests.
A B S T R A C TThis study was conducted between 2010 and 2011. The goal of study is to identify mammal species in the area and determine factors threatening these species. As a result of field studies, totally 20 species were identified from the orders Eulipotyphla, Chiroptera, Lagomorpha, Rodentia, Carnivora, and Artiodactyla of Mammal class. Factors that threaten mammal species and protective measures were given.
