Geometric morphometrics is widely used to study underlying causal factors in phenotypic evolution and to reconstruct evolutionary history of phenotypes. However, non-linearities in the phenotypic landscape may exist such that analytical solutions der

Early shifts lead to big changesMammals represent one of the most morphologically diverse taxonomic groups. One of the unique features underlying this diversity is variability of the spine, which facilitates everything from flexibility for speedy run

Studies of morphological integration can provide insight into developmental patterns, even in extinct taxa known only from skeletal remains, thus making them an important tool for studies of evolutionary development. However, interpreting patterns of

The field of morphometrics is developing quickly and recent advances allow for geometric techniques to be applied easily to many zoological problems. This paper briefly introduces geometric morphometric techniques and then reviews selected areas wher

The Vancouver Island marmot is the most endangered mammal of Canada. Factors which have brought this population to the verge of extinction have not yet been fully elucidated, but the effects of deforestation and habitat fragmentation on survival rate

Environmental factors and competition in closely related sympatric species may result in character displacement or phenotypic convergence. We studied the effects of sympatry on size and shape of the skulls, mandibles and molars in two species of wate

Phenotypic integration is a pervasive characteristic of organisms. Numerous analyses have demonstrated that patterns of phenotypic integration are conserved across large clades, but that significant variation also exists. For example, heterochronic s
