Phylodynamic and phylogeographic reconstruction of beak and feather disease virus epidemiology and its implications for the international exotic bird trade. [PDF]

Transbound Emerg Dis, 2022
Abstract Beak and feather disease virus (BFDV) infects domestic and wild psittacine species and is able to cause progressive beak, claw and feather malformation and necrosis. In addition to having an impact on the health and welfare of domesticated birds, BFDV represents a significant threat to wild endangered species.

Mitochondrial Markers COI and 16S rRNA for the Molecular Identification of Parrots and Macaws Recovered From Illegal Trafficking in Three Areas of Colombia. [PDF]

Ecol Evol
We molecularly characterized parrots (Amazona spp.) and macaws (Ara spp.) rescued from illegal trafficking in Colombia using two mitochondrial markers (COI and 16S rRNA). The COI gene showed high resolution for species identification and revealed considerable intraspecific diversity, while 16S rRNA displayed limited taxonomic resolution.

Cavity‐nesting birds are limited by nesting habitat in Neotropical agricultural landscapes

Biotropica, Volume 55, Issue 5, Page 1045-1057, September 2023., 2023
Although cavity‐nesting bird diversity is highest in the tropics, little is known about how tropical birds use cavities, how agriculture affects their reproductive biology, and how effective nest boxes could be as a conservation strategy in tropical agriculture.

Characterization of artificial intelligence performance for lesion detection using synthetic lesions in PET imaging. [PDF]

Med Phys
Abstract Background The use of artificial intelligence (AI) for lesion detection has witnessed increased interest and efforts in recent years. Meanwhile, task‐specific characterization and comparison of AI performance is lacking as supportive evidence prior to its implementation in the clinical setting.

Serological Surveillance and Risk Factor Analysis for Parrot Bornavirus in Taiwan. [PDF]

Transbound Emerg Dis
Parrots are traded globally and pose a substantial risk for disease transmission involving parrot‐specific pathogens. Parrot bornavirus (PaBV) belongs to the Bornaviridae family and encompasses two clades: alphapsittaciforme (PaBV‐1 to ‐4, PaBV‐7, and ‐8) and betapsittaciforme (PaBV‐5 and PaBV‐6). These clades cause proventricular dilatation disease, a

Phylogeography of the white-crowned parrot (Pionus senilis)

Biota Neotropica, 2022
Abstract The white-crowned parrot Pionus senilis (von Spix, 1824) is distributed throughout Middle America, inhabiting the Gulf of Mexico coastal area from Tamaulipas (Mexico) to northern Panama. We used mitochondrial data (COI, ND2 and ND4) from 55 specimens to infer phylogenetic relationships, and analyzed the phylogeographic structure, genetic ...
