Article
Beaked whales (Family Ziphiidae, Odontoceti, Cetacea) are one of the least studied groups of cetaceans. Their preference for shelf slope or deep ocean waters, long dives, low surface profile, elusiveness, and lack of visible blow in most species makes them difficult to spot, especially in rougher sea-state conditions. Due to these features, some sp...

We have studied several samples from Lotus corniculatus s. l. and L. zhegulensis populations with the use of SSR and sequenced nuclear (ITS) and plastid (atpB-rbcL, ndhC-trnV, rpl32-trnL(UAG), trnH-psbA, trnL-trnF) markers. We analysed 9 local populations from the Volga River valley ranging from Ulyanovsk in the north to Volgograd in the south, as...

The problem of cryptic species is well known in taxonomy of different groups of organisms, including plants, and their recognition can contribute to the assessment of global biodiversity and the development of conservation methods. Analyses of Lotus glareosus and related taxa from the Iberian Peninsula based on various types of data (i.e. sequences...

The monodontids—narwhals, Monodon monoceros, and belugas, Delphinapterus leucas—are found in much of the Arctic and in some subarctic areas. They are hunted by indigenous subsistence users. In the past, some populations were substantially reduced by commercial hunting and culling; more recently, some populations have declined due to uncontrolled su...

In 2000, the International Whaling Commission conducted a global assessment of beluga whales, Delphinapterus leucas. Following this assessment, five beluga stocks were recognized in Russian Far East waters: Western Chukchi-East Siberian Sea, Anadyr Gulf, Shelikhov, Sakhalin-Amur, and Shantar. This paper provides a revised assessment of beluga abun...

On the basis of the allelic composition of ten microsatellite loci and mtDNA sequences, we studied the genetic structure of the common hamster populations that inhabit cities and suburban settlements in Ciscaucasia. It was shown that, in urbanized territories, the hamster population is divided into separated groups, the genetic differences between...

The Lotus corniculatus complex (Fabaceae, Loteae) includes diploids (2n = 2x = 12) and tetraploids (2n = 4x = 24). Monophyly of the complex was supported by recent phylogenetic analyses, but evolutionary relationships within it remain debatable. The present study aims to outline species relationships in the L. corniculatus complex and evolutionary...

In the North Pacific, fish-eating R-type 'resident' and mammal-eating T-type 'transient' killer whales do not interbreed and differ in ecology and behavior. Full-length mitochondrial genomes (about 16.4 kbp) were sequenced and assembled for 12 R-type and 14 T-type killer whale samples from different areas of the western North Pacific. All R-type in...

The Common hamster (Cricetus cricetus) is the rodent with one of the largest range (6 million km2). There were four phylogenetic lineages earlier recovered in Western Europe, Ukraine and Bryansk Province of Russia: “North”, “Рannonia”, E1 and E0. E1 was previously reported from South-Eastern Poland and Western Ukraine and never been found in sympat...

The genetic structure of seven natural sable populations was investigated with the use of the original panel of 10 microsatellite loci. The populations were selected on the basis of the historical data on sable numbers fluctuations for the last 300 years, as well as on data on natural and artificial migrations affecting neighboring populations. We...
