Data from: Bat species comparisons based on external morphology: a test of traditional versus geometric morphometric approaches

- 摘要:
- differences between species lay in the extent to which the wing reaches in the direction of the head. This strong trend in interspecific shape

- 摘要:
- a reduction in the adjacent face cuticle. Our shape analysis also demonstrates that D. mauritiana eyes are specifically enlarged in the dorsal region
Data from: Evolution of neck vertebral shape and neck retraction at the transition to modern turtles: an integrated geometric morphometric approach

- 摘要:
- of evolutionary modifications to vertebral morphology. By reconstructing and visualizing ancestral anatomical shapes we provide insight into the anatomical fea
Data from: Mouth asymmetry in the textbook example of scale-eating cichlid fish is not a discrete dimorphism after all

- 摘要:
- morphological trait, where left and right forms are equally frequent within a species. We investigated the degree and the shape of the frequency distribution of head
Data from: Rapid morphological divergence of a stream fish in response to changes in water flow

- 摘要:
- in P. vigilax populations following dam construction in each of seven different rivers. Significant changes in body depth, head shape and fin placement wer
Data from: Disentangling the drivers of diversification in an imperiled group of freshwater fishes (Cyprinodontiformes: Goodeidae)
- 负责人:
- DOI:
- doi:10.5061/dryad.pc5gc05
- 摘要:
- (locomotor) regions were compared between subfamilies. No significant differences in evolutionary shape rates were recovered when the trophic (head) regions
Data from: Three-dimensional analysis of the fast-start escape response of the least killifish, Heterandria formosa
