Population dynamics of a migrant songbird : do we need to monitor the entire breeding season?
(University of Missouri--Columbia, 2011)
In Missouri, long-distance migrant songbirds can have relatively long breeding seasons, extending all the way into September for some species. Early models that assessed population status throughout the Midwest determined ...
Non-breeding competition between migrant American Redstarts (Setophaga ruticilla) and resident Adelaide's warblers (Dendroica adelaidae) in the Guanica Biosphere Reserve, southwest Puerto Rico
(University of Missouri--Columbia, 2011)
I tested the hypothesis that migratory American Redstarts (Redstart; Setophaga ruticilla) and resident Adelaide's Warbler (Adelaide's; Dendroica adelaidae) compete for food in a dry forest of southwest Puerto Rico. Competition ...
Cause specific mortality and anti-predator behavior in midwestern songbirds
(University of Missouri--Columbia, 2011)
Predation is a ubiquitous selective pressure that profoundly influences animals on evolutionary and ecological time-scales, but we lack estimates of predator-specific mortality rates for many taxa. We investigated ...
