Influence of entomopathogenic fungi from forest and urban habitats on founding pairs of reticulitermes flavipes (rhinotermitidae)
In forest habitats, termites break down woody debris and assist in nutrient cycling of carbon and nitrogen. However, infestations in suburban habitats have given subterranean termites a high priority for pest management. Biological control of subterranean termites has been unsuccessful using …

Diversity, structure and dynamics of an Acacia Erioloba woodland in the Windhoek area: Insights for the management of urban habitats
… and economic importance is threatened by urban expansion and a lack of sustainable management in the Windhoek area. The overall objective of this study was to determine the diversity and structure of an Acacia erioloba woodland and the influence of herbivory, wood harvesting, fire and …

Temporal, Spatial, and Environmental Influences on the Demographics and Harvest Vulnerability of American Black Bears (Ursus americanus ) in Urban Habitats in New Jersey, Pennsylvania and West Virginia
… ecology of black bears (Ursus americanus) in urban and suburban habitats, and there is limited information regarding black bear space use, habitat selection, and harvest vulnerability. I assessed the harvest vulnerability, home range size, and spatial ecology of black bears in New Jersey, …

Attraction and risk in urban bird habitats
Urban expansion is an increasing threat to native bird populations. Consequently, maintaining and developing safe urban habitat space is necessary for conservation. Birds living in, or migrating through, urban areas utilize a variety of managed green-spaces such as parks, gardens, college campuses, …

Carrion-associated arthropods in rural and urban environments
… that are attracted to pig carcasses in rural and urban habitats in Northwest Indiana. The species and number of carrion-associated arthropods that are found at a carcass vary with habitat type, month, and stage of decomposition. Lucilia sericata (Diptera: Calliphoridae) is a synanthropic species …

Behavior, Physiology, and Reproduction of Urban and Rural Song Sparrows (Melospiza Melodia)
Urban areas are a unique and growing habitat type. Animals living in this novel habitat are faced with new challenges, but may also encounter novel opportunities. Though urban animals have been observed to differ from their rural counterparts in a variety of behavioral and physiological traits, …

Physiological costs of total cholesterol in European starlings across an urban to rural gradient
<p>Urban areas—characterized by high human densities and associated buildings and impermeable surfaces—are increasing globally and represents a leading threat to wildlife that is drastically altering the natural resources they are accustomed to. Prior studies suggest that living in urban habitats …

Ecology of wintering Canada geese in the greater Chicago metropolitan area
… winter, Canada geese are increasingly using urban areas, but data are lacking on habitat use and selection, movements, potential thermal benefits of selected habitats, and survival of Canada geese during late autumn and winter in urban areas. I captured Canada geese during November‒February …

Urbanization affects environmental conditions for developing songbirds
Urbanization introduces a set of novel stressors for animals in these modified habitats. Developing young, in particular, can be at risk due to increased predation, exposure, and high food intake requirements. Song sparrows (Melospiza melodia) are a model wild songbird system that persist in both …

Detection probabilities and local population demographics of fishes in urbanized and forested streams of the New River basin, Virginia
… to address the mechanisms of impairment in urban stream habitats. When estimating population-level parameters, incomplete detection of individuals must be accounted for to ensure unbiased estimates. In this thesis, I examined differences in the detection probabilities of stream fishes, and …

Effects of urbanization on the physiology, behavior, and fitness of a wild songbird
As urbanization spreads, understanding its impact on wildlife is increasingly urgent. By comparing the traits and fitness of individuals within the same species found in both urban and rural habitats (urban adapters), we can better understand the behavioral and physiological coping mechanisms wild …

The ManhattAnt: Identification, natural history, and nutritional ecology of a recently introduced pest in New York City, Lasius emarginatus (Hymenoptera: Formicidae)
… has become among the most common urban ant species in New York City and has begun to spread outside the city. While the initial discovery of a new ant in New York City made national headlines and produced the memorable nickname the “ManhattAnt,” it was never formally identified and …

From nest building to life-history patterns: does food supplementation influence reproductive behaviour of birds?
… feeding of both Blue and Great Tits in urban habitats from 1962 to 2008 influenced breeding parameters across the study period but measuring food availability across wide spatial scales remains problematic. I discuss the implications of my results within an urban garden bird feeding …

A curate's egg: feeding birds during reproduction is 'good in parts'. A study of blue tits Cyanistes caeruleus and great tits Parus major
… of reproduction of blue and great tits in urban habitats across the UK. I discuss the implications of my findings, including the use of food supplementation in avian conservation and in pure scientific research, and I outline exciting future directions.

Microhabitat Affinity of Blanchard's Cricket Frog (Acris crepitans blanchardi) in Rural and Urban Areas in Central Texas
Habitats of small anurans are being encroached upon by land development in central Texas. Blanchard’s cricket frog (Acris crepitans blanchardi) is a small frog occupying small streams in these areas of disturbance. I investigated microhabitat affinity of Blanchard’s cricket frog to assess whether …

Comparing four indices of physiological stress in an urban-adapted songbird between urban and rural habitats
… to which different species tolerate life in urban habitats, yet it remains unclear why some species thrive while others cannot. My work explores possible phenotypes that make an urban-adapted species, the European starling (<em>Sturnus vulgaris</em>), so successful in both rural and urban …

Effects of interspecific competition, salinity, and hurricanes on the success of an invasive fish, the Rio Grande cichlid (Herichthys cyanoguttatus)
… It is often the most common fish species in urban canals and has also been found in natural waterways outside of the GNOMA. The effects and potential for further spread of H. cyanoguttatus is uncertain. My research addressed how extensive the cichlids spread in the GNOMA, how H. cyanoguttatus …

The distribution and ecology of invasive ant species in the Pacific region
… communities were sampled from litter and canopy habitats. Results suggested that body size, habitat and resource utilisation interact to create opportunities for invasion, and influence the susceptibility of different habitats. Habitat also shaped the assembly of ant communities and mediated …
