Density And Nest Success Of Shrub-Dependent Birds On Formerly Strip-Mined Lands, Luke Headings
Density And Nest Success Of Shrub-Dependent Birds On Formerly Strip-Mined Lands, Luke Headings
Electronic Theses & Dissertations
As bird populations continue to decline across North America, it is important to understand the benefits that disturbed habitats can have for breeding birds. One of the major land disturbances and causes of habitat loss in the United States is surface mining, which often results in altered vegetative communities. The primary goal of this study was to evaluate the relationships between bird populations, habitat, previous and current land use, and densities of invasive plant species on formerly strip-mined land. Due to the proliferation of invasive shrub species in post-mined landscapes, we sought to determine the effects of post-mined habitat features …
Predictors Of Summer Chloride Concentrations In Urban Aquatic Ecosystems, Georgianna S. Fischer
Predictors Of Summer Chloride Concentrations In Urban Aquatic Ecosystems, Georgianna S. Fischer
Honors Theses and Capstones
Urban aquatic ecosystems are highly threatened by excess concentrations of chloride (Cl-), which can negatively impact the biodiversity and functioning of aquatic ecosystems. High Cl- concentrations in most northern cities come primarily from road salt use for de-icing, in the form of NaCl. Specific pathways of runoff and hydrology of waterbodies will regulate Cl-concentrations in the months after the snowmelt season. This study attempted to understand the hydrologic controls on Cl- concentrations and identify how the hydrology of urban ecosystems may impact exposure to chloride in streams. To accomplish this, stream sites around the …
