Rapid scavenging of avian carcasses in the desert Southwest: Implications for mortality surveys not associated with infrastructure

open access: yesWildlife Society Bulletin, EarlyView.
We placed 214 avian carcasses in a desert environment at locations not associated with infrastructure and monitored their removal by scavengers using camera traps. We found that 211 of the 214 carcasses were scavenged and median persistence time was 1.53 days. None of the predictor variables were informative of carcass persistence times.

Hematological plasticity in House Sparrow populations in the Western Himalayas suggests recent range expansion to higher elevations

open access: yesAvian Conservation and Ecology
Organisms encounter significant challenges at high elevations because of hypoxic conditions. Therefore, exploring the physiological responses of organisms in these environments provides valuable insights into their adaptive strategies and evolutionary ...

Male age is associated with extra-pair paternity, but not with extra-pair mating behaviour [PDF]

open access: yes, 2017
Extra-pair paternity is the result of copulation between a female and a male other than her social partner. In socially monogamous birds, old males are most likely to sire extra-pair offspring.

Cardiovascular Plasticity and Adaptation of High‐Altitude Birds and Mammals

open access: yesIntegrative Zoology, EarlyView.
This schematic depicts the cardiovascular adaptations of mammals and birds to high‐altitude hypoxia. It highlights key phenotypic changes in oxygen transport and cardiac responses, driven by molecular mechanisms including transcriptional regulation and genetic modifications.

Urbanization and Vector Species Shape Avian Malaria Prevalence in Mosquitoes

open access: yesIntegrative Zoology, EarlyView.
Avian malaria prevalence was assessed in two mosquito species across urban and peri‐urban habitats. No infections were detected in either species in urban areas, while a 2.53% prevalence was found in the native Culex pipiens from peri‐urban sites, highlighting the influence of urbanization on parasite transmission dynamics.

A Survey of Neospora caninum infection in sparrows (Passer domesticus) in Khuzestan Province, Iran

open access: yesArchives of Razi Institute, 2015
The present study reports the presence of N. caninum DNA by PCR in brain tissues of house sparrows. The results showed that 6 (2.8%) of brain samples were positive for N. caninum. This is the first report for detection of N.

Prey Partitioning in a Diverse Carnivore Community: Implications for Reintroduced Fishers in Washington

open access: yesAnimal Conservation, EarlyView.
Using fecal DNA metabarcoding, we quantified dietary overlap among reintroduced fishers and sympatric coyotes, bobcats, and Pacific martens in Washington's North Cascades. Niche overlap was substantial for common prey but varied with body size, revealing fine‐scale resource partitioning that may limit fishers' access to energetically efficient prey ...
