By contrast, in M. In this case, at larger sizes, there is increased bite force, improved prey handling efficiency, and a consequent shift to larger and harder foods Verwaijen et al. On the other hand, much importance has been given to the three-dimensional representation 3D to estimate the variations due to the shape in an evolutionary context.

According Polly and MacLeod , the success of our 3D eigensurface method, while qualified, is encouraging. Eigensurface analysis of the 3D topography of calcanea sorted them into the same functional spectrum that qualitative functional analysis would have. While 3D surface scans of complicated morphological structures e. On the other hand, according to Bruner et al. Concerning the length of the frontal scales, Bruner et al. In relation to clinal variation, there are no studies indicating that the scales tend to differ with latitude.
However, using the scales as a reflection of the bones suggests that they are good indicators of change at this level Costantini et al. In the case of M.

Results The analysis did not find significant differences in form among the five localities, in contrast to the proposal of earlier studies, and no differences were recorded between the sexes. Conclusions Our results show that there are no differences between the studied, among the explanations are that populations of this species are subjected to similar environments that promote convergence of the structures analyzed. Background The genus Microlophus Squamata: Tropiduridae has a disjunct distribution, rare in terrestrial vertebrates Benavides et al. Did you know that since , Biblio has used its profits to build 12 public libraries in rural villages of South America?
Biblio is a marketplace for book collectors comprised of thousands of independent, professional booksellers, located all over the world, who list their books for sale online so that customers like you can find them! When you place your order through Biblio, the seller will ship it directly to you. This reflects the percentage of orders the seller has received and filled.
Stars are assigned as follows:. Inventory on Biblio is continually updated, but because much of our booksellers' inventory is uncommon or even one-of-a-kind, stock-outs do happen from time to time. If for any reason your order is not available to ship, you will not be charged.
Your order is also backed by our In-Stock Guarantee! What makes Biblio different?
