Evolutionary covariation in geometric morphometric data: analyzing integration, modularity, and allometry in a phylogenetic context
CP Klingenberg, J Marugán-Lobón - Systematic biology, 2013 - academic.oup.com
Quantifying integration and modularity of evolutionary changes in morphometric traits is
crucial for understanding how organismal shapes evolve. For this purpose, comparative …

How to make a bird skull: major transitions in the evolution of the avian cranium, paedomorphosis, and the beak as a surrogate hand
The avian skull is distinctive in its construction and in its function. Much of bird anatomical
variety is expressed in the beak; but the beak itself, largely formed of the premaxillary bone …

A morphometric study on the skull of the turkeys (Meleagris gallopavo)
In this study, 80 turkey skulls (40 females and 40 males) were used. Turkeys slaughtered at
the age of 128 days. The females had an average weight of 11.5 kg and the males had 19 …

Integration of skeletal traits in some passerines: impact (or the lack thereof) of body mass, phylogeny, diet and habitat
OV Shatkovska, M Ghazali - Journal of Anatomy, 2020 - Wiley Online Library
Morphological integration of the bird skeleton is of great interest because it relates to issues
of specialization, plasticity, and rate of evolutionary transformations of a skeleton as a whole …

Ecological and life-history drivers of avian skull evolution
One of the most famous examples of adaptive radiation is that of the Galápagos finches,
where skull morphology, particularly the beak, varies with feeding ecology. Yet increasingly …
