WHAT PREDICTS TERRESTRIAL INVERTEBRATE SUBSIDY USE BY BROOK TROUT (SALVELINUS FONTINALIS) IN HEADWATER STREAMS?
… critical resources for organisms in receiving habitats, particularly when production in those habitats is low. While it is clear that terrestrial invertebrates provide a critical subsidy for trout, including eastern brook trout (Salvelinus fontinalis), we have limited understanding of what …

The red imported fire ant, Solenopsis invicta, in early-successional coastal plain forests: tests of distribution and interaction strength
… is an abundant and aggressive component of early-successional communities in the southeastern United States. After disturbance, it rapidly invades new habitats, and once there, it has strong competitive and predatory effects on the existing arthropod community. In upland coastal plain pine …

Detection, habitat use, and occupancy dynamics of Black-billed Cuckoos and Yellow-billed Cuckoos in Illinois
… estimates are not always well supported and habitat requirements are poorly understood. Low detection and weak habitat associations could be due in part to wide-ranging movements within and between breeding seasons. I set out to examine detection probability, habitat use, and movement …

Avian population and community dynamics in response to vegetation restoration on reclaimed mine lands in southwest Virginia
… after mining, there may be potential to create early successional habitat needed by many avian species currently in decline throughout eastern North America. I evaluated nest-site selection and nest success for on reclaimed mine lands in southwest Virginia during the summers of 2010 and 2011. …

Effects of group selection and clearcut openings on wildlife in Appalachian hardwood forests
… large group selection openings provided breeding habitat for the same bird species. The smaller group selection openings were not used by some species found in the clearcut openings. However, creating a variety of opening sizes probably will provide the maximum benefit for all wildlife species …

Investigating Causal Relationships between Global Change and Insect Interaction Networks: Insights into Dietary Specialization, Interaction Diversity, and Disturbances
… occupy more space across all elevations and habitats. At a larger scale, I examined latitudinal gradients in network specialization and interaction diversity using long-term plant-caterpillar-parasitoid datasets from temperate and tropical regions. I found a weak but detectable latitudinal …

Response of Vegetation and Endangered Waterbirds to Habitat Management Techniques at Kealia Pond National Wildlife Refuge
<p>Habitat selection, reproductive effort, and habitat utilization of Hawai’ian stilts (Himantopus mexicanus knudseni) and Hawai’ian coots (Fulica alai) was studied on Kealia Pond National Wildlife Refuge in Mau’i, Hawai’i. Nesting behavior was confirmed following management treatments on the …

Multiscale Resource Selection of Ruffed Grouse in the Black Hills National Forest of South Dakota and Wyoming
… Parks had interest in assessing the status and habitat requirements of ruffed grouse in the BHNF. The objective or our study was to assess resource selection of ruffed grouse at multiple spatial scales in order to identify the most appropriate scale to manage for ruffed grouse as the MIS for …

Impacts of non-renewable resource extraction on shrubland songbird nest success and abundance
… land use changes and resulting loss of shrubland habitat. Land management practices which produce early-successional habitat, namely field abandonment and clearcut timber harvests, have become increasingly uncommon in the eastern United States, and natural maintenance processes such as fires and …

Spring Dispersal and Breeding Ecology of Northern Bobwhite in Southwest Ohio
… with economic and social importance. Despite nearly a century of research, population declines continue at state and national scales. Precipitous population declines and range-contractions in the Midwest have been caused by land-use changes and suppression of natural disturbance regimes. …

Piping Plover (Charadrius melodus) habitat selection, survival, and migration on New York barrier islands following natural and engineered habitat changes
… Its population decline was attributed to habitat loss, predation, coastal development, and disturbance. Hurricane Sandy reached the Northeast United States in October, 2012. The storm breached and overwashed two barrier islands of New York that support breeding piping plovers, Fire Island …
