Estimating Impervious Surface Cover in Flathead County, Montana
… opportunities that are unique to that area. Impervious surfaces can serve as a suitable proxy for tracking the spread of various anthropogenic influences on an ecosystem; it impacts groundwater recharge, increases overall surface runoff as well as pollution and sediment load, and fragments …

Effects of Canopy Cover and Impervious Surface Cover on Occurrence of Coyotes (Canis latrans) and Gray Foxes (Urocyon cinereoargenteus) throughout the United States
… scales. My study examined the effect of canopy cover, presumably an important component of natural habitat, and impervious surface cover as an indicator of urbanization, on the occurrence of coyotes and gray foxes. Additionally, I determined whether associations with canopy cover and impervious …

Variation in Salamander Life History and Community Composition Across an Urban Gradient in Atlanta, Georgia, USA
… a better predictor of stream temperature than impervious surface cover; 2) cooler August temperatures predicted a longer larval period and smaller larvae; 3) higher impervious surface cover predicted larger larvae and larger adult females; 4) larger females were associated with significantly …

Investigating the Role of Long Distance Dispersal in the Response of Stream Fishes to Urbanization
… a heavily impacted urban stream (watershed impervious surface cover ~30%) and a mildly impacted rural stream (watershed impervious surface cover ~6%). Species of interest were marked with 12mm HPT PIT tags and included a specialist, <em>Campostoma oligolepis </em>(n=189 urban site, 200 rural …

A GIS and Remote Sensing Based Analysis of Impervious Surface Influences on Bald Eagle (Haliaeetus leucocephalus) Nest Presence in the Virginia Portion of the Chesapeake Bay
… and land type, distance to land type and impervious surface cover area. Data plots revealed bald eagle nest presence decreases in response to an increase in area of bareland; increases with an increase in area of forested land; decreases with an increase in distance (m) to shoreline, and …

Characterization of Rain and Stormwater Nitrogen Inputs to the Mississippi Sound: A Landscape Approach
… important issue in the world. Increased impervious surface cover, a factor of urbanization, has drawn more attention to stormwater runoff as a source of contamination to receiving waters. In this study, nitrogen species from rain and stormwater were analyzed across three different …

An Assessment of Radiative, Energy and Carbon Dioxide Fluxes over Three Urban Locations in Dublin
… varies across and within cities serving to alter surface-atmosphere exchanges of radiation, turbulent heat and carbon dioxide. To date very few measurements of these exchanges are undertaken in the urban domain despite the growing number of urban dwellers worldwide. This thesis presents the first …

Does Urbanization Facilitate the Establishment of Introduced Monk Parakeet (Myiopsitta monachus) Populations?
… across the United States. I used tree canopy cover and percent impervious surface data from the 2016 National Land Cover Database GIS layers, surface water features from the National Hydrography Dataset, and observations and location data from eBird to find nest locations that were then …

Population Dynamics and Occupancy Patterns of Eastern Screech Owls (Megascops Asio) in New York City Parks and Adjacent Suburbs
… modeled as functions of the amount of forest cover and impervious surface cover at each survey point. These models were validated against an independent dataset collected by myself and other trained scientists. Validated models indicated a negative association between occupancy and percent …

Spatial urban and peri-urban biodiversity patterns
… are influenced by landscape composition (land cover) and specific habitat characteristics. For this, the urban landscape was described in terms of an urbanisation gradient: the study area was stratified into three zones of decreasing urbanisation, namely the urban (> 50% built cover), the …

Evaluating the impacts of urbanization and stormwater management practices on stream response
… of urban development and limiting percent of impervious surface cover. In this study, protocols were developed to help standardize data generation for identifying mechanistic linkages to provide public agencies with tools to identify management practices that will achieve the fewest ecological …

The Impacts of Climate and Landscape Change on Catchment Scale Material Transport in High Mountain and Seasonally Cold Regions
… of armored stream channels and by increases in impervious surface cover. To investigate these landscape changes on chloride transport and storage, two years of streamflow and chloride concentration data were used to create continuous chloride load estimates for two contrasting reaches of an …

STORMWATER MANAGEMENT PRACTICE MONITORING USING LONG-TERM TIME LAPSE ELECTRICAL RESISTIVITY TOMOGRAPHY AND SOIL SENSORS: IMPLICATIONS FOR DESIGN, MAINTENANCE, AND SOIL MOISTURE MONITORING
Due to the large amount of impervious surface cover, urban areas are at high risk for flooding and, in cities with combined sewer systems, subject to sewer overflow during heavy storm events. The Pennsylvania Department of Transportation (PennDot) is currently reconstructing and expanding parts of …
