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 ...
Seasonality and elevational migration in an Andean bird community
(University of Missouri--Columbia, 2010)
Life history strategies of many birds in the Neotropics remain poorly known. In particular, details on the seasonal movements of individuals and populations within the Neotropics remain largely unknown, including short-distance ...
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 ...
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 ...
Mature forest-breeding bird use of early-successional habitat
(University of Missouri--Columbia, 2013)
Some late-successional birds shift habitat-use from mature forestbreeding habitat to early-successional habitat. Management efforts have primarily focused on breeding habitat for migratory songbirds, but the post-breeding ...
Spatial ecology of Western Ratsnakes (Pantherophis obsoletus) : implications for bird nest predation
(University of Missouri--Columbia, 2014)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] In fragmented Midwestern forests, many birds face high rates of nest predation, to the point where this region may serve as a population sink for some ...
Influence of habitat selection and habitat quality on the demography of a neotropical migrant songbird, the Bell's vireo (Vireo bellii)
(University of Missouri--Columbia, 2013)
Individual fitness varies with the quality of the habitat occupied. Variation in habitat quality is difficult to assess, particularly in heterogeneous habitats where quality may differ within a single patch. Individuals ...
Nesting and postfledging ecology of Neotropical migrant songbirds in Missouri forest fragments
(University of Missouri--Columbia, 2016)
The postfledging period, after fledging and before migration, is a critical stage for Neotropical migrant songbirds. The postfledging period encompasses an interval of high mortality that can greatly affect population ...
