| historical biogeography at the crossroads of the northern continents: molecular phylogenetics of red-backed voles (rodentia: arvicolinae). | evolutionary relationships of red-backed voles and their relatives were examined and used to test biogeographic hypotheses. sequences of the mitochondrial cytochrome b gene were obtained for 25 individuals representing alticola macrotis, clethrionomys californicus, c. gapperi, c. glareolus, c. rutilus, and c. rufocanus. these were combined with 21 partial sequences from genbank for c. regulus, c. rex, c. rufocanus, c. rutilus, eothenomys imaizumii, e. melanogaster, phaulomys andersoni, and p. sm ... | 2004 | 15012954 |
| [the morphological variability coordinated with the population cycle of the widely distributed (the water vole arvicola terrestris l.) and mountain (the big-eared vole alticola macrotis radde) vole species]. | this paper presents an analysis of variation of skull size and shape in the course of population cycles of two ecologically different vole species: water vole and high-mountain vole. we have found consistent changes of the direction, rate, and balance of morphogenesis during population cycles. we discuss the role of intra-populational factors and inter-populational variation during the territorial expansion of the species. | 2016 | 10780114 |
| [variability of satellite dna in 2 groups of field mice (rodentia, microtinae)]. | nuclear dnas of three forms of microtus juldashi--m. carruthersi (group 1) and of three subspecies of polytypic species alticola macrotis (group 2) were compared. intensive interpopulational karyotype differentiation was observed in both groups, particularly, for centromeric heterochromatin quantity and localization. as satellite dnas (satdnas) were present in c-heterochromatin of the rodents groups studied, the latter were used as a model for comparison of the satdnas in the species in statu na ... | 2012 | 3539700 |
