Geometric Morphometrics
The field of morphometrics is developing quickly and recent advances allow for geometric techniques to be applied easily to many zoological problems. This article briefly introduces geometric morphometric techniques and then reviews selected areas where those techniques have been applied to questions of general interest. This article is relevant to non-specialists looking for an entry into geom...
متن کاملdetermination of meriones species (rodentia, gerbillinae) by rapd-pcr
meriones crassus, meriones persicus, and meriones libycus from different areas of khorasan provinces and yazd province were studied by use of random amplified dna polymorphism (rapd) technique. dna samples were analyzed by use of nine primers. genetic distance among samples varied between 0.24 and 0.78. dendrogram designed on the base of genetic distance shows separation of these species. in th...
متن کاملGeometric morphometrics and phylogeny
This paper reviews some of the important properties of geometric morphometric shape variables and discusses the advantages and limitations of the use of such data in studies of phylogeny. A method for fitting morphometric data to a phylogeny (i.e., estimating ancestral states of the shape variables) is presented using the squared-change parsimony criterion for estimation. These results are then...
متن کاملSerological Differentiation of Two Species of Taterillus
I. The sera of two species of Taterillus, T. gracilis and T. pygargus, were analysed by electrophoresis with different media: acetate, starch gel and acrylamide. 2. The two principal fractions, albumin and transferrin, appear to have different mobilities according to the species and consequently can be used to differentiate these two species which are indistinguishable by the usual tests. 3. Th...
