Inbreeding and demography interact to impact population recovery from bottlenecks [PDF]

Biodiversity loss driven by climate change and human activities poses a critical global challenge. Population restoration and reintroduction programs are essential for mitigating this threat, yet their outcomes are often unpredictable due to poorly ...

Good vibrations: remote‐tactile foraging success of wading birds is positively affected by the water content of substrates they forage in

Journal of Avian Biology, Volume 2024, Issue 9-10, September/October 2024.
Some taxa of wading birds can locate buried prey by detecting vibratory cues in their foraging substrates while probe‐foraging, using a sensory modality called ‘remote‐touch'. As more saturated substrates transmit vibrations better, we predict that these birds can detect prey in wetter substrates more easily.

Effects of Environmental Stress on the Parental Behavior in Crested Ibis (Nipponia nippon)

Journal of the Yamashina Institute for Ornithology, 2003
When maintained in captivity in 'intensive aviaries' that offered suboptimal and unnatural living conditions, parent Crested Ibis successfully incubated their eggs but subsequently killed the chicks and discarded them at the point of hatching. In order to investigate this aberrant behavior, new 'semi-natural' breeding cages were established in natural ...

When birds of a feather flock together: Severe genomic erosion and the implications for genetic rescue in an endangered island passerine

Evolutionary Applications, Volume 17, Issue 7, July 2024.
Abstract The Seychelles magpie‐robin's (SMR) five island populations exhibit some of the lowest recorded levels of genetic diversity among endangered birds, and high levels of inbreeding. These populations collapsed during the 20th century, and the species was listed as Critically Endangered in the IUCN Red List in 1994.

Genetic diversity of the critically endangered Blue‐crowned laughingthrush (Garrulax courtoisi) 极度濒危的蓝冠噪鹛 (Garrulax courtoisi) 的遗传多样性

Wildlife Letters, Volume 2, Issue 2, Page 73-82, June 2024.
Molecular markers are widely used in conservation genetics of wildlife. A total of 15 novel microsatellite loci with high polymorphism of Blue‐crowned laughingthrush were developed in this study. The genetic diversity level of wild individuals was higher than two captive populations including Ocean Park Hong Kong and Nanchang Zoo. The genetic diversity

Bactérias presentes em filhotes de guará (Eudocimus ruber), baía babitonga, estado de Santa Catarina, Brasil [PDF]

, 2018
Wild birds are important for public health because of their potential to transmit pathogenic microorganisms to humans. The waterbird scarlet ibis (Eudocimus ruber) forages and breeds near urban areas and if they settle near polluted waters, the viability

Comprehensive analysis and risk assessment of antibiotic contaminants and the antibiotic resistance of Escherichia coli from crested ibis

Ecotoxicology and Environmental Safety
The environmental quality of habitat is a critical determinant of animal survival. In this study, we conducted a comprehensive analysis of ten antibiotic residues in habitats of the crested ibis (Nipponia nippon).

A new threshold selection method for species distribution models with presence‐only data: Extracting the mutation point of the P/E curve by threshold regression

Ecology and Evolution, Volume 14, Issue 4, April 2024.
This study proposes a new method named Boyce‐Threshold Quantile Regression (BTQR). The method uses threshold regression to locate the mutation point of Boyce's predicted‐to‐expected curve. Analysis based on source‐sink theory suggests that this mutation point may represent a transition in habitat types and serve as an appropriate threshold. Comparative

Genomic signatures of near-extinction and rebirth of the crested ibis and other endangered bird species [PDF]

Background: Nearly one-quarter of all avian species is either threatened or nearly threatened. Of these, 73 species are currently being rescued from going extinct in wildlife sanctuaries.
