Spatiotemporal Modeling for Wildlife Demographic Analysis: Bridging Analysis to Waterfowl Conservation
… spatial nature of this system and highlight conservation issues for midcontinent mallard populations. My second chapter serves as a guide to using spatially explicit models in population ecology. In a comprehensive literature review, I discuss spatial autocorrelation in demographic models and …

Assessing the impact of greentree reservoir water management on red oak growth and anatomy in the lower Mississippi Alluvial Valley
… and hydrologic alteration. To preserve migratory waterfowl habitat, greentree reservoirs (GTRs) were established, providing artificial flooding during the fall and winter. Red oak species within GTRs provide vital resources, such as mast and habitat for wildlife, and make up an important part of …

Ecology of spring-migrating waterfowl within the lower Wabash River floodplain
… is an understudied, but important time for waterfowl as conditions faced during this period may affect reproductive success. Therefore, increasing our understanding of waterfowl ecology during spring is vital for maintaining desired population levels. The Midwestern United States has lost …

Ecology of fall-migrating ducks in central Illinois: a radar perspective
… (28 days) that has been use for regional waterfowl conservation planning. I also regressed average annual stopover duration estimates against an index of annual foraging habitat quality and found a strong, positive relationship (r2 = 0.71), suggesting ducks assessed local habitat …

Impacts of habitat and landscape characteristics on reproductive ecology of female lesser scaup (Aythya affinis) in the boreal forests of Alberta
… during the 1980s and has remained below conservation objectives. With two-thirds of the breeding population nesting in boreal forests, it is imperative to understand how changes in habitat features and landscape changes could negatively impact breeding scaup; this information could also …

The Foraging Ecology, Habitat Use, and Population Dynamics of the Laysan teal (Anas laysanensis)
… are fundamental to the species management and conservation. I described diel and nocturnal habitat use, home range, and foraging with radio telemetry in 1998-2000. Most individuals showed strong site fidelity during the tracking period, but habitat selection varied between individuals. Mean …
