Helminthes fauna of sable (Martes zibellina Linnaeus)in Yakutia

The Sable dwelled practically all taiga zones in Yakutia to 60-s of the last centuryresulting the hunt prohibition, artificial distribution and conservation measures. From70-s, Sable became one from main hunt for fur species in Republic.Many-years data (1981-2008) on infestation of Sable with helminthes invasion aregeneralized with the goal to establish the helminthes species composition and infestationdegree at the present. The tasks of researching were: to study space and time dynamicsof Sable infestation with helminthes and to reveal dependence degree of invasion extensivenessand intensity from an owner sex, age and number in Yakutia conditions.1548 Sables from seven regions of Yakutia were examined for helminthes infestationin the shown period (south Yakutia - 347, south-western -363, western - 217, central -138, north-western - 254, Kolyma-Indigirka district - 57 and Northeastern Yakutia -172). Common infestation rate of the Yakutia sable made up 46,0%. Eight helminthesspecies were found - Taenia martis (Zeder, 1803), Taenia mustelae Gmelin, 1790, Mesocestoideslineatus (Goeze, 1782), Ascaris columnaris Leidy, 1856, Molineus patens (Duj.,1845), Capillaria putorii (Rudolphi, 1819), Soboliphyme baturini Petrov, 1930, Syphaciaobvelata (Rudolphi, 1802) belonging to two classes - cestodes and nematodes. Therewere 3 cestodes species - Taenia martis, Taenia mustelae, Mesocestoides lineatus withtotal infestation rate - 37,3%; and five nematodes - Ascaris columnaris, Molineus patens,Capillaria putorii, Soboliphyme baturini, Syphacia obvelata with total infestationrate 12,6%. Nematode Soboliphyme baturini was found in Sable inhabiting the southernareas firstly in Yakutia. Two nematodes species recorded for Sables of South Yakutia(Sobolephyme baturini, Syphacia obvelata) are absent in the rest of districts of Yakutia.Studied 1548 specimens of Sables were infested mostly with cestodes - Taenia martis(29,8%) and nematodes - Ascaris columnaris (6,4%). Sex and age differences in infestationof Sables were revealed: male infestation (44,5±3,6%) is lower as compared to females(48,1±2,7%). However, this difference is not significant statistically (t=0,9). Invasionextensiveness of young animals (50,0±2,2%) is greater than in adults (38,7±3,3%).This difference is statistically significant (t=2,8). Top infestation (55,4±5,7%) is reportedin 2003 with the population growth of sable and the lowest one (31,8±7,0%) at the speciesnumber decrease in 1995. The difference is statistically significant (t=2,6).
