Reprodução do papagaio charão, Amazona pretrei (Aves: Psittacidae) em cativeiro. [PDF]
Ciência Florestal, 2009 O papagaio charão, Amazona pretrei (Temminck, 1830) pode ser reproduzido em cativeiro. O viveiro deve ser amplo para que o comportamento de acasalamento e reprodução seja o mais semelhante ao ambiente natural.

Novel food resources and conservation of ecological interactions between the Andean Araucaria and the Austral parakeet. [PDF]
Ecol Evol, 2022 The results of this study show that the inter‐annual dependence of Austral parakeets on native habitats is influenced by the masting seed production strategy of Araucaria, a key species in the northern Patagonian Andes. Currently, this dependence seems to be largely modulated by disturbing factors promoting a feeding shift to exotic plants in anthropic

Endangered plant-parrot mutualisms: seed tolerance to predation makes parrots pervasive dispersers of the Parana pine. [PDF]
Sci Rep, 2016 Parrots are largely considered plant antagonists as they usually destroy the seeds they feed on. However, there is evidence that parrots may also act as seed dispersers.

Molecular markers for population genetic analyses in the family Psittacidae (Psittaciformes, Aves) [PDF]
Genetics and Molecular Biology, 2006 The selection of molecular markers for population studies is an important tool for biodiversity conservation. The family Psittacidae contains many endangered and vulnerable species and we tested three kinds of molecular markers for their potential use in
