Effect of heating and glycation on the allergenicity of 2S albumins (Ara h 2/6) from peanut [PDF]

open access: yes, 2011
Although no effect of processing on T-cell reactivity was observed, heat induced denaturation reduced the IgE reactivity and subsequent functionality of Ara h 2/6.

Chromosomal Diversity and Karyotype Evolution in South American Macaws (Psittaciformes, Psittacidae). [PDF]

open access: yesPLoS ONE, 2015
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

Records of two species of Parrots (Psittacidae) and hybrid in urban and rural areas of Armenia, Colombia

open access: yesActa Biológica Colombiana, 2016
The naturalization of non-native species has been well documented in temperate zones, but little is known about tropical regions. Understanding the process of expanding geographic range of species generated management and conservation strategies. In this

In silico identification and characterization of novel microsatellite loci for the Blue-and-yellow Macaw Ara ararauna (Linnaeus, 1758) (Psittaciformes, Psittacidae)

open access: yesGenetics and Molecular Biology, 2019
The illegal trade is a major threat to many bird species, and parrots are common victims of this activity. Domestic and international pet markets are interested on different parrot species, such as the Blue-and-yellow Macaw (Ara ararauna).

Volatile Compounds in Feathers of the Scarlet Macaw (Ara macao) Reflect Sex and Pair‐Bond Status

open access: yesIntegrative Zoology, EarlyView.
Scarlet macaws exhibit sex‐ and pair‐related differences in plumage volatile composition, with males showing greater chemical richness. Partnered individuals differ in specific compound classes, whereas no clear association with immune function was detected. These results support a potential role for olfactory cues in sexual and social communication in

Importance of using genetic data to inform conservation captive breeding: A tale of two species of threatened macaws (Ara spp.)

open access: yesConservation Science and Practice, Volume 8, Issue 10, October 2026.
Unmanaged captive populations of threatened species often harbor hidden genetic risks, so using genomic tools, we audited a large private macaw collection and uncovered extensive hybridization and high inbreeding. Our findings provide an actionable framework for how routine genetic screening can be used to mitigate these risks, manage captive breeding ...

Fatal Paratanaisia bragai (Digenea: Eucotylidae) infection in scarlet macaws (Ara macao) in Costa Rica [PDF]

open access: yesActa Parasitologica, 2015
AbstractWe report on four fatal cases of renal infection due to Paratanaisia bragai in scarlet macaws (Ara macao) from two rescue centres in Costa Rica. At necropsy, birds had severe dehydration and cachexia. Two birds had hydropericardium, oedematous lungs, and liver lipidic degeneration.
