Determining habitat and biotic factors driving puma (<i>Puma concolor</i>) space use and underlying dynamic processes (colonization and extinction) over 20 years in protected and private areas throughout Belize, Central America
… and habitat. We used single-species, single-season and multi-season occupancy modeling to explore factors influencing distribution and persistence of pumas across the country of Belize. We used camera trapping data from 7 protected areas over 20 years with 2,198 camera stations covering …

BRIDGING AQUATIC AND TERRESTRIAL ECOSYSTEMS: ECOLOGY OF SEMI-AQUATIC MAMMALS IN SOUTHERN ILLINOIS
… related to the probability of detection, initial occupancy, colonization, and extinction of the 4 semi-aquatic mammals in southern Illinois; and (2) to test if the reintroduction of river otter has changed stream food webs. To address my first objective, I sampled 120 bridge sites in 2 periods …

Occupancy and Abundance of Golden-cheeked Warblers (Dendroica chrysoparia) on the Balcones Canyonlands Preserve
… each site. Count data were analyzed using both multi-season occupancy models and binomial mixture models (BMM) to estimate each observer's probability of detection at both the species and individual level. Model selection revealed that observer had a strong influence on detection of GCW A. I …

Ecology of the marsh rice rat (Oryzomys palustris) in southern Illinois: wetland dynamics, metapopulations, and trophic position
… to assess the spatial and temporal variation in occupancy and turnover rates of a semi-aquatic small mammal at 2 hydrologically distinct wetland complexes over 3 years in southern Illinois. My second objective was to determine spatio-temporal variation in the trophic structure of small mammals at …

Effects of non-native woody plant species on shrubland birds of conservation concern
… scales of habitat selection influenced birds’ occupancy dynamics, as well as how the three most abundant non-native shrub in Illinois (autumn olive (Elaeagnus umbellata), honeysuckle (Lonicera spp.) and multiflora rose (Rosa multiflora)), influenced birds’ physiological health and condition. I …
