| temperature can interact with landscape factors to affect songbird productivity. | increased temperatures and more extreme weather patterns associated with global climate change can interact with other factors that regulate animal populations, but many climate change studies do not incorporate other threats to wildlife in their analyses. we used 20 years of nest-monitoring data from study sites across a gradient of habitat fragmentation in missouri, usa, to investigate the relative influence of weather variables (temperature and precipitation) and landscape factors (forest cov ... | 2013 | 23504884 |
| declining brown-headed cowbird (molothrus ater) populations are associated with landscape-specific reductions in brood parasitism and increases in songbird productivity. | many songbird species have experienced significant population declines, partly because of brood parasitism by the brown-headed cowbird (molothrus ater), which is positively associated with increasing landscape forest cover in the midwestern united states. however, cowbirds are also experiencing long-term population declines, which should reduce parasitism pressure and thus increase productivity of host species. we used 20 years of nest monitoring data from five sites in missouri across a gradien ... | 2012 | 23077647 |
| species-specific variation in nesting and postfledging resource selection for two forest breeding migrant songbirds. | habitat selection is a fundamental component of community ecology, population ecology, and evolutionary biology and can be especially important to species with complex annual habitat requirements, such as migratory birds. resource preferences on the breeding grounds may change during the postfledging period for migrant songbirds, however, the degree to which selection changes, timing of change, and whether all or only a few species alter their resource use is unclear. we compared resource select ... | 2017 | 28614414 |
