Evaluation of autumn mist‐netting data for monitoring passerine populations in interior Alaska

Wildlife Society Bulletin, 2012
We evaluated the data from 2 autumn mist‐netting stations for monitoring passerine population trends and measuring the timing of migration. Migration‐monitoring stations were operated during autumn from 1993 to 2009 at 2 interior Alaska locations: in ...

Time Spent With Parents Varies With Early-Life Condition, but Does Not Predict Survival or Sociality of Juvenile Hihi

Frontiers in Ecology and Evolution, 2019
Many young birds die soon after fledging, as they lack the skills to find food and avoid predation. Post-fledging parental care is assumed to assist acquisition of these vital skills. However, we still lack empirical examples examining the length of time

Sperm design and variation in the New World blackbirds (Icteridae) [PDF]

, 2009
Post-copulatory sexual selection (PCSS) is thought to be one of the evolutionary forces responsible for the rapid and divergent evolution of sperm design. However, whereas in some taxa particular sperm traits are positively associated with PCSS, in other

Comparative transcriptomics of 3 high-altitude passerine birds and their low-altitude relatives

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance One potential limitation of the understanding of high-altitude adaptation is that most previous research focused on individual species, without taking into account the phylogenetic context in which similar genetic adaptations may have ...

Reproductive success of the wood warbler Phylloscopus sibilatrix varies across Europe

Journal of Avian Biology, 2022
Differences in population trends across a species' breeding range are ultimately linked to variation in demographic rates. In small songbirds, demographic rates related to fecundity typically have strong effects on population trends.

Fine-scale population structure and asymmetrical dispersal in an obligate salt-marsh passerine, the Saltmarsh Sparrow (Ammodramus Caudacutus) [PDF]

, 2012
Understanding the spatial scale of gene flow can yield valuable insight into the ecology of an organism and guide conservation strategies. Fine-scale genetic structure is uncommon in migratory passerines because of their high vagility and presumed high ...

Little Adaptive Potential in a Threatened Passerine Bird.

Current Biology, 2019
Threatened species face numerous threats, including future challenges triggered by global change. A possible way to cope with these challenges is through adaptive evolution, which requires adaptive potential.

Phylogenetic relationship and characterization of the complete chloroplast genome of the alpine leaf-warbler in Qinghai-Tibet Plateau

Mitochondrial DNA. Part B. Resources, 2019
The Alpine Leaf-warbler (Phylloscopus occisinensis) is a small-sized and poorly-known songbird endemic to China. In this study, we sequenced and described the whole mitochondrial genome of the Alpine leaf-warbler.

Infection by a helminth parasite is associated with changes in DNA methylation in the house sparrow

Ecology and Evolution, 2022
Parasites can exert strong selective pressures on their hosts and influence the evolution of host immunity. While several studies have examined the genetic basis for parasite resistance, the role of epigenetics in the immune response to parasites is less

Timing avian long-distance migration: from internal clock mechanisms to global flights [PDF]

, 2017
Migratory birds regularly perform impressive long-distance flights, which are timed relative to the anticipated environmental resources at destination areas that can be several thousand kilometres away.
