The evolutionary history of cockatoos (Aves: Psittaciformes: Cacatuidae) [PDF]

Molecular Phylogenetics and Evolution, 2011
Cockatoos are the distinctive family Cacatuidae, a major lineage of the order of parrots (Psittaciformes) and distributed throughout the Australasian region of the world. However, the evolutionary history of cockatoos is not well understood. We investigated the phylogeny of cockatoos based on three mitochondrial and three nuclear DNA genes obtained ...

Can the intake of antiparasitic secondary metabolites explain the low prevalence of hemoparasites among wild Psittaciformes?

Parasites & Vectors, 2018
Background Parasites can exert selection pressure on their hosts through effects on survival, on reproductive success, on sexually selected ornament, with important ecological and evolutionary consequences, such as changes in population viability ...

Fit for purpose? Analysis of the relationship between skull, beak shape and feeding ecology in Psittaciformes. [PDF]

J Anat
Psittaciformes exhibit high levels of morphological diversity, particularly in skull and beak structure, previously linked to diet and body size. Although there were some levels of significance between diet and beak shape, body mass was a much stronger co‐variate. Diet is not determining beak shape within the clade.

Assessing the Genetic Health and Conservation Value of an Introduced Urban Population of a Critically Endangered Parrot. [PDF]

Evol Appl
ABSTRACT Non‐native species can be introduced to novel environments such as cities via wildlife trade. These populations may have conservation value—particularly if they are of a species threatened in its native range. Genetic tools can help assess the fitness of introduced populations by indicating if they are (1) suffering the consequences typically ...
