Population genetic structure of the blue-fronted Amazon (Amazona aestiva, Psittacidae: Aves) based on nuclear microsatellite loci: implications for conservation.
The blue-fronted Amazon (Amazona aestiva) is a widely distributed Neotropical parrot and one of the most captured parrots in nature to supply the illegal trade of wild animals. The objectives of the present study were to analyze the genetic structure of A. aestiva to identify management units and support conservation planning and to verified if A. aestiva populations have undergone a recent bot...

15 صفحه اولChromosomal Diversity and Karyotype Evolution in South American Macaws (Psittaciformes, Psittacidae)
Most species of macaws, which represent the largest species of Neotropical Psittacidae, characterized by their long tails and exuberant colours, are endangered, mainly because of hunting, illegal trade and habitat destruction. Long tailed species seem to represent a monophyletic group within Psittacidae, supported by cytogenetic data. Hence, these species show karyotypes with predominance of bi...
متن کاملSociality and Reconciliation in Monk Parakeets (Myiopsitta monachus)
For animals living within socially complex groups, it is beneficial for all individuals to maintain group cohesion. Conflicts often arise in groups, which could potentially have high costs both to the subordinate and dominant members, and could lead to group instability. It has been shown numerous times that highly social group members participate in affiliative relationships with other group m...
متن کاملPhylogeny and Biogeography of the Amazona Ochrocephala (aves: Psittacidae) Complex
•We present a phylogenetic analysis of relationships among members of the Amazona ochrocephala species complex of parrots, a broadly distributed group in Middle and South America that has been a "taxonomic headache." Mitochondrial DNA sequence data are used to infer phylogenetic relationships among most of the named subspecies in the complex. Sequence-based phylogenies show that Middle American...
