This study was carried out to determine the shape of fox skull by geometric morphometric method according gender. For this purpose, four female and nine male skulls were used. The photographed from dorsal lateral aspects. Eleven homologous landmarks on aspect 19 marked photographs skull. Principal component analysis Relative warp performed coordinate values images. In addition, MorphoJ software...

Echinococcus multilocularis, a causative agent of alveolar hydatidosis, is becoming a serious problem in Hokkaido, the northernmost island of Japan (1,2). E. multilocularis is maintained among its definitive hosts, such as red foxes, Vulpes vulpes shrencki, and dogs, and its intermediate host, wild voles such as Clethrionomys rufocanus bedfordiae, in Hokkaido. The average infection rate of E. m...

A case of wildlife trichinosis was found in a red fox (Vulpes vulpes japonica) captured at Rokkasho, Aomori Prefecture on November 27, 1998. Trichinella larvae were obtained from almost all of the muscle tissues except for the masseter. The highest number of larvae per gram of tissue was found in the muscles of the gluteal region and throat. The lowest number was found in the diaphragm and tong...

The red fox is a highly adaptable mammal that has established itself world-wide in many different environments. Contributing to its success social structure based on chemical signalling between individuals. Urine scent marking behaviour long been known foxes, but there not recent study of the composition urine. We have used solid-phase microextraction and gas chromatography-mass spectrometry an...

The RAPD-PCR technique was applied to identify genetic markers able to distinguish between four canid species: the arctic fox (Alopex lagopus), red fox (Vulpes vulpes), Chinese raccoon dog (Nyctereutes procyonoides procyonoides) and six breeds of the domestic dog (Canis familiaris). A total of 29 ten-nucleotide arbitrary primers were screened for their potential use in the differentiation of th...

The aim of this study was to analyse meiotic cells of male interspecific hybrids of the red fox (Vulpes vulpes) and the arctic fox (Alopex lagopus). To this end we determined stages of meiotic cells as well as carried out FISH analyses with probes specific to heterosomes and a TUNEL assay on synaptonemal complex preparations. The meiotic cell analysis revealed only the presence of stages of the...

Studies on red fox Vulpes vulpes biology, including habitat and food preferences have been very popular during recent decades. However, the majority of them were mainly carried out mainly in highly human-modified habitats. In this paper we present data on the diet of the red fox, with special attention to domestic poultry and on den site selection in extensive farmland in Poland. During the yea...
