Many nontropical animals display physiological and behavioural changes in response to seasonal environmental cues including photoperiod (day length). Male Siberian hamsters (Phodopus sungorus) housed in short photoperiod undergo testicular regression accompanied by reduced circulating testosterone and decreased reproductive behaviour. By contrast to the majority of small mammals studied, aggres...

Genetic data consisting of immunoglobulin testing (GM and KM) from 631 Eskimos from 5 populations are reported. These populations are Savoonga, Gambell (St. Lawrence Island), Wales, King Island, and Mckenzie Delta, Baffin Island. The GM and KM haplotypes are analyzed and compared to those occurring in Greenland, Canadian, Alaskan, and Siberian Eskimos and to other Siberian indigenous population...

Based on field studies, museums collections and literature sources, the current knowledge of the tiger beetle fauna of Israel and adjacent lands is presented. In Israel eight species occur, one of them with two subspecies, while in the Sinai Peninsula nine species of tiger beetles are now known. In the combined regions seven genera from two tribes were found. The Rift Valley with six cicindelid...

This paper shows new preimage attacks on reduced Tiger and SHA-2. Indesteege and Preneel presented a preimage attack on Tiger reduced to 13 rounds (out of 24) with a complexity of 2. Our new preimage attack finds a one-block preimage of Tiger reduced to 16 rounds with a complexity of 2. The proposed attack is based on meet-in-themiddle attacks. It seems difficult to find “independent words” of ...

Tiger moths (Erebidae: Arctiinae) have experienced intense selective pressure from echolocating, insectivorous bats for over 65 million years. One outcome has been the evolution of acoustic signals that advertise the presence of toxins sequestered from the moths' larval host plants, i.e. acoustic aposematism. Little is known about the effectiveness of tiger moth anti-bat sounds in their natural...

The mtDNA variation of 411 individuals from 10 aboriginal Siberian populations was analyzed in an effort to delineate the relationships between Siberian and Native American populations. All mtDNAs were characterized by PCR amplification and restriction analysis, and a subset of them was characterized by control region sequencing. The resulting data were then compiled with previous mtDNA data fr...

Siberia and Northwestern Russia are home to over 40 culturally and linguistically diverse indigenous ethnic groups, yet genetic variation and histories of peoples from this region are largely uncharacterized. We present deep whole-genome sequencing data (∼38×) from 28 individuals belonging to 14 distinct indigenous populations from that region. We combined these data sets with additional 32 mod...

Complete blood counts and blood chemistry in four Siberian husky puppies diagnosed with swimming puppy syndrome were compared with four healthy Siberian husky puppies. Only serum creatine kinase in affected puppies was significantly (P < 0.01) higher than in normal puppies. Although serum creatine kinase level cannot be used for diagnosis of this disease, it could serve as a tool for prognosis ...

The paper considers mechanisms for organizing free trade in the electricity market that are based on submitting bids of energy consumers and producers to the market operator. The authors discuss and compare possible strategies of generator behavior that lead to different equilibrium situations and correspond to Cournot model and the models of supply function equilibria, and a perfectly competit...
