Зоология за БългариAuthors: Ito M, Jiang W, Sato JJ, Zhen Q, Jiao W, Goto K, Sato H, Ishiwata K, Oku Y, Chai JJ, Kamiya H Rodents belonging to the subfamily Gerbillinae and living in the Xinjiang-Uygur autonomous region of China were collected in field surveys between 2001 and 2003. We found four Meriones species, including M. chengi M. liycus, M. meridianus, and M. tamariscinus, as well as related species from different genera, Rhombomys opimus and Brachiones przewaliskii For phylogenetic analyses of these gerbilline species, DNA sequences of parts of the mitochondrial cytochrome b (Cytb) and cytochrome c oxidase subunit II (COII) genes were examined with the neighbor Joining, maximum parsimony, maximum likelihood, and Bayesian inference methods. Our phylogenetic analyses suggest that the genus Meriones...Зоологията в Интернет

Зоология за БългариAuthors: Kojima S Partial nucleotide sequences ( approximately 8000 bp) of the mitochondrial DNA of two cerithioidean gastropod species-Cerithidea djadjariensis and Batillaria cumingi-were determined. The order of mitochondrial genes (eight protein genes, two ribosomal RNA genes, and nine transfer RNA genes) was identical between these two species. and remarkably different from the previously reported order in other gastropods. The results indicate that the genome structure of the common ancestor of Cerithioidea and its sister group, Hypsogastropoda, is almost identical to that of the common ancestor of Gastropoda; moreover, independent mitochondrial genome rearrangements were identified between the lineages of Cerithioidea and Hypsogastropoda. The rearrangements within Cerithioidea ca...Зоологията в Интернет
