Epigeal invertebrates of Yorkshire allotments: the influence of urban-rural gradient and management style
There is a growing interest in urban ecology but it can be a difficult environment for wildlife due to a range of anthropogenic pressures. Allotments could be used to study this issue but they have been rather neglected in terms of academic research, particularly in relation to their biodiversity …

Environmental Gradients Impact Key Leaf Traits in Riparian Trees
… response of two riparian tree species along the urban-rural gradient in Northeastern Colorado: an invasive, nitrogen-fixer with broad tolerances and a nitrogen-limited and shade-intolerant native. Despite these differences, the two species responded similarly, apart from the response to the …

UNDERSTANDING THE INFLUENCE OF ANTHROPOGENIC HABITAT MODIFICATION ON URBAN ANIMALS: CASE STUDIES OF CARRIBEAN LIZARDS AND NORTH AMERICAN MAMMALS
Global urbanization is rapidly expanding, leading to habitat degradation and fragmentation, which present strong challenges for native wildlife. At the same time, urbanization is often accompanied by the introduction of non-native species, which alter community and habitat structures. These changes …

Biogeochemical effects of an invasive grass across a land-use gradient: linking alterations of nitrogen cycling to depleted soil carbon pools
… invader’s impacts on soil C across a land-use gradient. To do this, I quantified the effects of M. vimineum on belowground C and N dynamics and enzyme activities in forests across a 45-km urban-rural gradient in Southern Appalachia, USA. Consistent with previous reports, invasion was associated …

Effects of Urbanization on the Avian Community of Oak Woodlands
… land necessary to sustain them. With this urban expansion comes a myriad of effects on both native habitat and wildlife. In birds, these effects can have a variety of negative impacts on behavior and physical health. Habitat degradation, largely through various forms of pollution, leads to …

Impacts of Urban Areas on Vegetation Development Along Rural-Urban Gradients in the Upper Midwest: 2003-2012
… projected to increase by 2.5 billion by 2050 in urban areas alone (United Nations 2014). The rapid urbanization of our planet drives global environmental changes in hydrosystems, biodiversity, biogeochemical cycles, land use and land cover, and climate (Grimm et al. 2008). Urban areas alter local …

Variation drives response to urbanisation: Evolutionary ecology of two introduced birds within anthropogenic environments : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
… to novel stimuli is a major challenge for urban and rural wildlife and is linked with their fitness. These responses will likely differ between urban and rural habitats as well. Populations will show behavioural and morphological variation along an urban-rural gradient in response to …
