phylogeography and genetic diversity of the lesser mouse- eared bat (myotis blythii) in iran
in current study, 63 samples of bat populations collected from differ regions were used for evaluating the geographic variations. twenty cranial and dental characters for traditional morphometric and landmarks method on the ventral, dorsal skull and mandible for geometry morphometric studies were used. statistical analyses of traditional morphometric and geometry morphometric data indicated low...
Morphometrics as an Insight Into Processes Beyond Tooth Shape Variation in a Bank Vole Population
Phenotype variation is a key feature in evolution, being produced by development and the target of the screening by selection. We focus here on a variable morphological feature: the third upper molar (UM3) of the bank vole, aiming at identifying the sources of this variation. Size and shape of the UM3 occlusal surface was quantified in successive samples of a bank vole population. The first sou...
متن کاملGenetic variation in amount of salivary amylase in the bank vole, Clethrionomys glareola.
Several investigated bank vole populations are polymorphis for the number of salivary amylase loci, and individual chromosomes may carry one, two or three linked amylase structural genes. In the present study, we have used bank vole stocks homozygous for different chromosomes to investigate the relationship between amylase production and gene number. By measuring the amylase activity in parotid...
متن کاملGenetic Variation in Bank Vole Populations in Natural and Metal-Contaminated Areas
The effects of isolation and heavy-metal pollution on genetic diversity in Myodes (=Clethrionomys) glareolus populations were studied. Isolation and pollution are considered to have important effects on biodiversity. Animals were collected from ten populations in isolated (island), mainland, and metal-polluted areas. Three populations were in areas near zinc and lead smelters; four were on isla...
متن کاملSeasonal changes of population genetic structure and relatedness in the bank vole Clethrionomys glareolus: An analysis of age cohorts
The genetic consequences of age structure were investigated in five populations of the bank vole, Clethrionomys glareolus, using 18 variable allozyme loci. Temporal samples and age cohorts were analysed to detect seasonal differences in population genetic structure and relatedness between individuals. Changes in allele frequencies between seasons were found in one population. While over-wintere...
