Analysis of variation in tooth size in a population of red fox, Vulpes vulpes (Linnaeus, 1758) from Poland based on three indices (coefficient of variation CV, variation index VSD, residual standard deviation RSD) and its correlation with average tooth size revealed two contradictory patterns. The CV and VSD were significantly correlated with average tooth sizes, while RSD values was independen...

In the present study, we describe an interspecific kleptoparasitic interaction between two sympatric mammalian carnivores in high altitudinal Trans-Himalaya region of Himachal Pradesh, India. The study was based on inferences drawn from circumstantial evidence (direct and indirect) noticed area Pin Valley National Park. analysis suggested a Snow Leopard Panthera uncia, Red Fox Vulpes vulpes, do...

Severe lung strongylosis was detected in a wild red fox (Vulpes vulpes) (1/12) from Apulia (Italy). We performed routine diagnostics on 12 foxes found dead in Apulia. Eleven of them showed lesions consistent with a vehicle collision. However, the remaining fox appeared to have died from other causes. At necropsy we observed, catarrhal enteritis, fatty liver, lung congestion with some areas rm i...

A key defining feature of a species' niche and ecological roles is its diet (Pocheville 2015). What an animal species eats influences trophic position, how it moves around, which other interacts with, among many behaviours. While diets are flexible, predators have evolved to forage optimally on certain prey types or (Hayward et al. 2011, 2016). The mechanisms that determine optimal foraging beh...

A wild young male red fox (Vulpes vulpes) was found in the mountainous hinterland of Rome (Italy) with a heavily depressed mental status and unresponsive to the surrounding environment. Neurological examination revealed depression, left circling, right head tilt, ventromedial positional strabismus and decreased postural reactions on the left side. Neurological abnormalities were suggestive of c...

Ecologists undertaking stable isotopic analyses of animal diets require trophic enrichment factors (TEFs) for the specific animal tissues that they are studying. Such basic data are available for a small number of species, so values from trophically or phylogenetically similar species are often substituted for missing values. By feeding a controlled diet to captive European badgers (Meles meles...
