Global distribution range of birds is negatively correlated with their level of diet specialization
Journal of Biogeography, Volume 51, Issue 10, Page 2062-2069, October 2024.Abstract Aim Understanding the factors determining the size of a species distribution range is crucial to preventing the extinction of vulnerable species, particularly specialist species. Previous research has shown that climate and various traits of a species significantly affect its distribution range size.

The Anatomical Record, Volume 307, Issue 1, Page 5-48, January 2024.Abstract To date, several studies describe post‐hatching ontogenetic variation in birds; however, none of these studies document and compare ontogenetic variation of the entire skull in multiple avian species. Therefore, we studied ontogenetic skull variation of two bird species with very different ecologies, Pica pica, and Struthio camelus, using μCT ...

Revista brasileira de parasitologia veterinaria = Brazilian journal of veterinary parasitology : Orgao Oficial do Colegio Brasileiro de Parasitologia Veterinaria, 2011 The aim of this research was to determine the prevalence of Cryptosporidium spp. in ostriches reared in the state of Rio de Janeiro. The diagnosis of oocysts of Cryptosporidium spp. in the feces of 77 ostriches was done by modified Ziehl-Neelsen technique. The occurrence was observed in 44.4% of the examined animals.
