Abstract:
In this study we consider the frequency of coat color variation among Yakutsk stray dogs. The study was carried out at the same time in three city districts: Centralniy, Saysarskiy and Stroitelniy. The districts differ in urban development and population density of stray dogs. The Stroitelniy and Saysarskiy Districts belong to a one-two-storey residential type of the building, the Centralniy one to a multi-storey residential type. 8 types of colors were distinguished: black, white, red, wolf-gray (agouti), yellow with a mask, black-backed, white large-spotted and black with white spots. The analysis of the morphs was carried out in percent, as well as Zhivotovskys indications: the average number of morphs (), proportion of rare phens (h), phonetic similarity of groups (r). The most frequent is a black-backed color 21,42% (95% confidence interval: 17,3326,92). The wolf-gray type of color 18,56% (CI: 14,0025,00) and the black with white spots type 15,62% (CI: 11,5420,00) are also very frequent. The white large-spotted color (4,62% CI: 3,336,67) is the least frequent among the selected types. It is proved that the population of stray dogs in Yakutsk is quite homogeneous. One-to-one comparison of stray dog groups from different districts of Yakutsk showed that the groups from the Centralniy and Stroitelniy Districts turned out to be the closest (r = 0,972 0,024). The lowest connection between dogs groups were observed in the Saysarskiy and Stroitelniy Districts (r = 0,933 0,029). The collation of the Centralniy and Saysarskiy Districts also revealed an analogy between these groups of stray dogs (r = 0,956 0,034). Therefore, the morphotype of stray dogs in Yakutsk is formed mainly without any human influence, mostly have a random pattern. Conditions of life can impact to the selection; as a result the most accommodated individuals survive on the street in the region with a severe climate.
