В статье приводятся сведения о вирусологическом и серологическом скрининге герпесвирусов в популяции каспийских тюленей. Показана устойчивая циркуляция тюленей первого типа (PhHV-1) среди Отмечено, что PhHV-1 является эндемичным для и, возможно, вызывает постоянную вирусную нагрузку на здоровье тюленей, которая усугубляется провоцирующими факторами. The article provides information on virologic...

We investigated dispersal patterns in the monogamous Crocidura russula, based both on direct field observations (mark-recapture data) and on genetic analyses (microsatellite loci). Natal dispersal was found to be low. Most juveniles settled within their natal territory or one immediately adjacent. Migration rate was estimated to two individuals per year and per population. The correlation betwe...

nutritional indices of the willow leaf beetle, plagiodera versicolora laicharting, third instar larvae and adults were studied on four host plants including salix alba l., salix aegyptica l., populus caspica bornm.and populus alba l.at 22 ± 2 ºc, 70 ± 10% r.h., and a photoperiod of 16:8 h (l: d). the results showed that the highest consumed food by the larvae and adults (148.5 ± 18.0 and 175.21...

In arid and semi-arid environments, desert vegetation plays an important role in preventing soil erosion by wind helps maintain the stability of oasis ecosystems. Four types typical vegetation, namely Populus euphratica, Haloxylon ammodendron, Nitraria sibirica, Halostachs caspica, corresponding to different habitats (i.e., river bank, sand dune, desert, salt marsh) were chosen as model this re...

Basal rate of metabolism (BMR) and resting maternal rate of metabolism around peak lactation (RMR(L)) were measured in Crocidura russula, Mus domesticus and Microtus arvalis. These species have a moderate or high BMR relative to the scaling relationship of Kleiber. One goal of the study was to check whether females of these species show elevated rates of metabolism during lactation. A second go...

This study investigated geographic variation in the Asian lesser white-toothed shrew, Crocidura shantungensis Miller, 1901, among a number of localities in East Asia, including the Korean Peninsula, Tsushima Island, Cheju Island, and Taiwan, using univariate and multivariate analyses of cranial morphometric characters. Sexual differences were found in Taiwanese shrews, but were not evident in t...
