Cranial ecomorphology of turtles and neck retraction as a possible trigger of ecological diversification

open access: yesEvolution, Volume 76, Issue 11, Page 2566-2586, November 2022., 2022
Abstract Turtles have a highly modified body plan, including a rigid shell that constrains postcranial anatomy. Skull morphology and neck mobility may therefore be key to ecological specialization in turtles. However, the ecological signal of turtle skull morphologies has not been rigorously evaluated, leaving uncertainties about the roles of ...

Web databases of feather photographs are useful tools for avian morphometry studies

open access: yesEcology and Evolution, Volume 11, Issue 12, Page 7677-7684, June 2021., 2021
Wing area and aspect ratio are key variables for studies of avian comparative ecology, despite the complexity of measuring them both in living and in museum specimens. The systematic databases of feather photographs available on the Internet may offer an alternative way of obtaining such morphometric data.
