Stopover Ecology and Habitat Use of Migratory Wilson's Warblers
--The conservation of long-distance migratory songbirds is complicated by their life-history characteristics and the spatial scales that they traverse. Events during migratory stopovers may have significant consequences in determining the population status of migratory songbirds. Using Wilson's Warbler (Wilsonia pusilla) as a focal species, we investigated effects of age and sex on stopover par...
متن کاملHabitat Associations of Song Characteristics in Phylloscopus and Hippolais Warblers
Ai•sTRACT.--Bird-song functions, such as mate attraction, species recognition, and territory defense, are closely linked to individual fitness. Thus, habitat characteristics that affect song transmission and degradation should exert a strong influence on the evolution of song attributes. Whereas different acoustic environments may influence the evolution of song characteristics, factors such as...
متن کاملPlumage Genes and Little Else Distinguish the Genomes of Hybridizing Warblers
When related taxa hybridize extensively, their genomes may become increasingly homogenized over time. This mixing via hybridization creates conservation challenges when it reduces genetic or phenotypic diversity and when it endangers previously distinct species via genetic swamping [1]. However, hybridization also facilitates admixture mapping of traits that distinguish each species and the ass...
متن کاملFine-scale genetic structure and fire-created habitat patchiness in the Australian allodapine bee, Exoneura nigrescens (Hymenoptera: Apidae).
Fire promotes an abundance of nest sites for the stem nesting bee Exoneura nigrescens, which remain viable for approximately 10 years. The finite duration of nesting substrate and localized fire events suggest that migration should minimize genetic structure among suitable habitat patches. Exoneura nigrescens was sampled from 7 localities with a known fire history in southwestern Victoria, Aust...
متن کاملThe variable genomic architecture of isolation between hybridizing species of house mice.
Studies of the genetics of hybrid zones can provide insight into the genomic architecture of species boundaries. By examining patterns of introgression of multiple loci across a hybrid zone, it may be possible to identify regions of the genome that have experienced selection. Here, we present a comparison of introgression in two replicate transects through the house mouse hybrid zone through ce...
