Wild carnivore habitat use and community ecology in a biodiversity hotspot and human-wildlife conflict with pumas and dogs across Chile
… mega-wildfire in 2017. I used dynamic occupancy modeling of human-wildlife conflict (HWC) across 52 provinces for 8 years in Chile and found that free-ranging dogs outpace pumas in livestock depredation, killing substantially more livestock than pumas. Occupancy models show that HWC …

Bat occupancy of forests and managed savanna and woodland in the Missouri Ozark Region
… of detection (p), and 2) determine how site occupancy (Ψ) varies among savannas, woodlands, and forests as a function of vegetation structure and management history for 5 common bat species in the Missouri Ozark region: big brown bat (Eptesicus fuscus), eastern red bat (Lasiurus borealis), …

Using Occupancy Models to Predict Grassland Bird Distributions in Southeastern Alberta
… to guiding long term management efforts. I used single-species, single-season occupancy models to (1) identify landscape factors influencing the distribution of grassland bird species, (2) generate predictions of species distributions in southeastern Alberta, and (3) evaluate the predictive …

Resource Selection, Home Range and Habitat Associations of the Southern Fox Squirrel (<i>Sciurus niger niger</i>) in the Piedmont and Coastal Plain of Virginia
… and fire suppression. Decrease in growing season burns, hardwood encroachment and forest mesophication have transformed pine hardwood woodlands and pine (Pinus spp.) savanna habitats that southern fox squirrels prefer to hardwood dominant habitats that eastern gray squirrels (Sciurus …

Ecological insight into three neotropical deer species: A study of spatial and diel distributions of white-tailed, Central American red brocket, and Yucatan brown brocket deer in northern Belize, Central America
… of the YBB in Belize. In Chapter 1, we used single-season occupancy modeling on WTD and RBD detections to estimate occupancy and identify habitat, predator, and anthropogenic drivers of species distribution and to quantify overlap in space use between the two species. WTD behaved as an …

Occupancy and Abundance of Golden-cheeked Warblers (Dendroica chrysoparia) on the Balcones Canyonlands Preserve
… 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 found …

EFFECTS OF SCALE AND HABITAT MANAGEMENT ON GRASSLAND BIRD RESPONSE IN CONSERVATION RESERVE PROGRAM FIELDS IN NORTHWEST ILLINOIS
… affecting site turnover, also known as dynamic occupancy, and daily nest survival rate (nest survival or DSR), as well as how multiple avian responses vary with grassland management would further benefit conservation decision making for focal species. I investigated dynamic occupancy and nest …

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
… lower trophic levels, 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 …

Multiscale patterns of mammal diversity and occurrence in the Karoo
… at the broadest scale wildlife diversity and occupancy was largely influenced by landscape–level abiotic processes, namely longitude and precipitation. None of the wide–ranging large predator (e.g., leopard or brown hyena) or endangered species (i.e., riverine rabbit) known to occur in the …

The influence of habitat features and co-occurring species on puma (Puma concolor) occupancy across eight sites in Belize, Central America
… American felids is particularly lacking. I used single- and multi-season, single-species occupancy models and two-species co-occurrence models to analyze camera trapping and habitat data collected at eight study sites across Belize. Puma occupancy was positively influenced by jaguar trap success, …
