Pleistocene glacial cycles play a major role in diversification and speciation, although the relative importance of isolation and expansion in driving diversification remains debated. We analysed mitochondrial DNA sequence data from 15 great reed warbler (Acrocephalus arundinaceus) populations distributed over the vast Eurasian breeding range of the species, and revealed unexpected postglacial ...

Heat shock proteins (HSPs) play a key role in anti-stress and immune processes are associated with autoimmune diseases. In order to explore the immunological of HSPs from Schizothorax prenanti (S. prenanti), SpHSP60 was cloned for first time this study, gene expressions SpHSP27, SpHSP60, SpHSP70 SpHSP90 hepatopancreas, head kidney, hindgut spleen were analyzed by quantitative real-time PCR (qPC...

Abstract Background Postzygote isolation is an important part of species isolation, especially for fish, and it can be divided into two aspects: genetic ecological isolation. With the increase in parental distance, intensity between them also increases. Will niche differences lead to them? This question difficult answer based on current literature due lack hybridization cases contrasting parent...
