Prevalence and Diversity of Haemosporidian-Associated Matryoshka RNA Viruses in a Natural Population of Wild Birds. [PDF]

Ecol Evol
This study investigated the prevalence and diversity of Matryoshka RNA viruses (MaRNAV) in wild birds in the San Francisco Bay Area, California. Using RNA sequencing and RT‐PCR, we identified two novel MaRNAVs (MaRNAV‐5 and ‐6) associated with haemosporidian infections in passerines and raptors. These findings suggest a high prevalence of these viruses,

Multidirectional chromosome painting substantiates the occurrence of extensive genomic reshuffling within Accipitriformes. [PDF]

, 2015
BACKGROUND: Previous cross-species painting studies with probes from chicken (Gallus gallus) chromosomes 1-10 and a paint pool of nineteen microchromosomes have revealed that the drastic karyotypic reorganization in Accipitridae is due to extensive ...

The shapes of bird beaks are highly controlled by nondietary factors [PDF]

, 2016
Bird beaks are textbook examples of ecological adaptation to diet, but their shapes are also controlled by genetic and developmental histories. To test the effects of these factors on the avian craniofacial skeleton, we conducted morphometric analyses on

Inclement weather forces stopovers and prevents migratory progress for obligate soaring migrants

Movement Ecology, 2021
Background Migrating birds experience weather conditions that change with time, which affect their decision to stop or resume migration. Soaring migrants are especially sensitive to changing weather conditions because they rely on the availability of ...

Vulture Exclusion Halves Large Carcass Decomposition Rates and Doubles Fly Abundance. [PDF]

Ecol Evol
We experimentally excluded vultures from pig carcasses (Sus scrofa) in Costa Rica, under different habitats and across seasons with the aim to assess the impact of vulture population decline on carrion decomposition and insect abundance. Vulture exclusion halved carcass decomposition rates and doubled fly abundance, while dung beetle abundance remained

The first whole genome and transcriptome of the cinereous vulture reveals adaptation in the gastric and immune defense systems and possible convergent evolution between the Old and New World vultures [PDF]

, 2015
Background: The cinereous vulture, Aegypius monachus, is the largest bird of prey and plays a key role in the ecosystem by removing carcasses, thus preventing the spread of diseases. Its feeding habits force it to cope with constant exposure to pathogens,

The value of avian genomics to the conservation of wildlife [PDF]

, 2009
Background: Genomic studies in non-domestic avian models, such as the California condor and white-throated sparrow, can lead to more comprehensive conservation plans and provide clues for understanding mechanisms affecting genetic variation, adaptation ...
