Isospora bocamontensis (Protozoa: Apicomplexa) in captive yellow cardinal Gubernatrix cristata (Passeriformes: Emberezidae) [PDF]

Pesquisa Veterinária Brasileira, 2013
The yellow cardinal (Gubernatrix cristata) is a passerine found in southern Brazil, especially along the border with Uruguay and Argentina. It is an endangered species and its population is decreasing. Among the parasites that affect passerines, the genus Isospora is the most easily found in both captive and free-living birds.

Vulnerability of Gubernatrix cristata to climate change, anthropogenic pressures, and hybridization threats. [PDF]

Sci Rep
Abstract Estimating extinction risk is challenging due to insufficient data on current and future threats. This study develops a framework incorporating the impacts of climate change, anthropogenic pressures, and biotic interactions for assessing extinction risks using the endangered Yellow Cardinal (Gubernatrix cristata) as a case study ...

Long read genome unravels MHC I genomic architecture, evolution, and diversity loss in <i>Gubernatrix cristata</i>. [PDF]

iScience
The major histocompatibility complex (MHC) genes are vital for the adaptive immune response in vertebrates and are widely used in conservation genetics to represent adaptive variation. Accurate genotyping of MHC alleles is essential for effective conservation, particularly for endangered species like the yellow cardinal (Gubernatrix cristata). However,

Karyotype Organization of the Endangered Species Yellow Cardinal (Gubernatrix cristata) [PDF]

DNA, 2021
Karyotypic analyses have several applications in studies of chromosome organization, evolution, and cytotaxonomy. They are also essential to genome assembly projects. Here, we present for the first time the karyotype description of the endangered species yellow cardinal, Gubernatrix cristata (Passeriformes, Thraupidae), using conventional staining with

Molecular diagnosis of avian viruses in grassland passerines and captive yellow cardinals Gubernatrix cristata in Brazil [PDF]

Pesquisa Veterinária Brasileira, 2021
ABSTRACT: Avian influenza viruses (AIVs), Newcastle disease virus (NDV), West Nile virus (WNV), adenovirus (AV) and herpesvirus (HV) play an important role in the health of human and animal populations. However, knowledge of the prevalence of these viruses in wild birds is restricted to some groups (e.g. shorebirds) or regions worldwide. Information on

Breeding biology of the endangered Yellow Cardinal Gubernatrix cristata in Brazil [PDF]

Revista Brasileira de Ornitologia, 2019
AbstractThe Yellow Cardinal,Gubernatrix cristata, has a small geographic range in Brazil, Uruguay, and Argentina. We studied the natural history of the only known Brazilian population of this “Endangered” species (∼50 individuals), which is socially monogamous and may breed cooperatively.

Population Monitoring of the Red Junglefowl Based on Acoustic Signal Recognition Technology. [PDF]

Ecol Evol
ABSTRACT Vocalisation is a crucial means of communication for birds and plays a key role in survival and reproductive success. Individual differences in songs have been used for identification in many animals, but few studies have integrated song individuality into wildlife population monitoring.
