Occupancy dynamics, personality, & behavior of Franklin's Ground Squirrel in agricultural landscapes
… area, and connectivity on patterns of site occupancy and extinction for P. franklinii at the landscape scale. While many methods are used to measure connectivity, debate about which metrics are preferred for applied conservation issues is ongoing. Thus, while investigating occupancy dynamics …

Deciphering genome-wide chromatin occupancy, dynamics, and their connections to gene regulation
… environmental conditions. Key changes to the occupancy profile of the chromatin may dictate changes in gene regulation or vice versa. Therefore, it is important to decipher the chromatin occupancy profiles of the genome and understand how these configurations are related to the transcription …

Detection, habitat use, and occupancy dynamics of Black-billed Cuckoos and Yellow-billed Cuckoos in Illinois
… detection probability, habitat use, and movement dynamics of both species. I performed passive and call-broadcast surveys for cuckoos at 41 sites throughout northern Illinois in 2019 and 2020. I examined the influence of call broadcast and temporal and environmental covariates on detection …

Effects of protected areas and climate change on the occupancy dynamics of common bird species in South Africa
… areas and climate change affect the range dynamics of common, resident bird species in South Africa. Common species were used because they have been shown to drive important ecosystem patterns, and a decline in abundance and diversity of common species can indicate drastic declines in …

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 …

Integrating multiple sign types to improve occupancy estimation for inconspicuous species: a case study of American pika in the Pacific Northwest
… critical for conservation and management. Occupancy models have emerged as one of the most powerful tools to investigate regional population trends and dynamics, range shifts and habitat associations. Standard occupancy models are capable of producing unbiased estimates of occupancy and its …

Habitat selection, survival, and disease risk of semiaquatic mammals in a highly altered landscape
… in east-central, Illinois. Annual model-averaged occupancy estimates of stream sites were correlated positively to summer precipitation for both American mink (Neovison vison) and muskrats (Ondatra zibethicus) suggesting a possible climate-change effect. Factors interplaying across multiple scales …

Spatial population dynamics of recolonizing wolves in the Western Alps
… of wolf population trend, survival rates, occupancy parameters, and on the development of a spatially explicit population model. These estimates were lacking in Italy and Western Europe, and accurate and cost effective methods to assess these parameters have not been implemented.<p> I used …

FACTORS INFLUENCING THE SPATIAL AND TEMPORAL STRUCTURE OF A CARNIVORE GUILD IN THE CENTRAL HARDWOOD REGION
… non-invasive carnivore survey using an occupancy modeling framework to quantify factors affecting the structure of this widely-occurring carnivore guild. I used baited remote cameras during 3-week surveys to detect carnivores at 1,118 camera-points in 357 2.6-km2 sections (clusters of …

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 …
