The effects of urbanization on winter avian diversity: a citizen science and GIS study
As the human population continuously increases, habitat transformation due to urban expansion is inevitable, affecting many wildlife species. Birds have become a frequently used model species for studying the effects of urbanization on wildlife populations due to their environmental sensitivity and …

Bird use of avocado farms and intact forest in the Dominican Republic
… endemism and overwintering Neotropical migrant habitats, is seeing an increase of avocado farms and a subsequent forest loss. We conducted point-count bird surveys to determine how avian species richness and diversity differ between avocado farms and intact forest, as well as how vegetation …

Changes in avian diversity and potential invasive seed dispersal post-wildfire in a Southeastern deciduous forest; Flipper Bend Woods, Signal Mountain, Tennessee
… (2016) presented a unique opportunity to analyze habitat regrowth two-three years after a major wildfire thought to have been worsened by invasive plants. In order to examine post-fire recovery and invasive plant recolonization, researchers observed the diversity of avian species in a burned and …

Thresholds in avian communities at multiple scales: Relationships between birds, forests, habitats, and landscapes in the Ray Roberts greenbelt, Denton
… forest corridors for wildlife dispersal between habitats in highly fragmented landscapes. Forest interior birds are of the most concern to management in riparian forests due to their population declines across much of their breeding range. This dissertation investigates the role that …

Riparian Forest Width and the Avian Community in a Greenbelt Corridor Setting
… threshold of 400-meters is suggested to provide habitat for forest interior species, which have lost considerable habitat through forest fragmentation. Partners in Flight breeding bird priority concern scores were used to create a habitat priority index for the Trinity River bottomland hardwood …

Habitat selection and breeding ecology of grassland birds in areas managed with fire and grazing
… bird populations in the Midwest. On top of habitat loss, the cessation of historic disturbance regimes on remaining grasslands has served to homogenize vegetation structure. Because grassland birds evolved in the context of the interactive disturbances of fire and grazing, their habitat …

Land Cover Change and the Breeding Bird Survey: Rates of Change in Relation to Roads
… been similar between road-side and non-road-side habitats, and if so, make assumptions whether or not they affect survey results of bird population metrics. In order to meet my goal, I propose to assess three primary objectives. Objective number 1 (Chapter 2) is to evaluate rates of change in …
