Tree leaf-associated microbiota have been studied in natural ecosystems but less so in urban settings, where anthropogenic pressures on trees could impact microbial communities and modify their interaction with their hosts. Additionally, trees act as vectors spreading bacterial cells in the air in urban environments due to the density of microbial cells on aerial plant surfaces. Characterizing ...

Our goal was to evaluate how avian assemblages varied along a gradient of urbanization in the highly fragmented landscape of coastal southern California. We measured species richness and abundance of birds within continuous blocks of habitat, within urban habitat fragments that varied in landscape and local habitat variables, and within the urban matrix at different distances from the wildland ...

Over long time periods, urbanization is expected to have a negative effect on species diversity. Predicted effects generally follow one of three competing paradigms: diversity decay, homogenization, or communitycomposition turnover. However, it has been hypothesized that urban green spaces may provide a means by which urban areas can maintain or increase their species diversity over time. We us...

PURPOSE/OBJECTIVES To understand the experiences of women having same-day breast cancer surgery and make recommendations to assist healthcare professionals effect change to enhance quality of care. RESEARCH APPROACH Thematic analysis of audiotaped interviews. SETTING Outpatient departments of two city hospitals on the east coast of Canada. PARTICIPANTS Purposive sample of 13 women who had...

Urbanization is one of the major anthropogenic processes contributing to local habitat loss and extirpation of numerous species, including wild bees, the most widespread pollinators. Little is known about the mechanisms through which urbanization impacts wild bee communities, or the types of urban green spaces that best promote their conservation in cities. The main objective of this study was ...

Urbanization has been cited as an important factor in worldwide amphibian declines, and although recent work has illustrated the important influence of broad-scale ecological patterns and processes on amphibian populations, little is known about the factors structuring amphibian communities in urban landscapes. We therefore examined amphibian community responses to wetland habitat availability ...

Urban adolescents are exposed to a substantial amount of community violence which has the potential to influence psychological functioning. To examine the relationship between community violence exposure and mental health symptoms in urban adolescents, a literature review using MEDLINE, CINAHL, PubMed, PsycINFO, CSA Social Services and CSA Sociological Abstracts was conducted. Search terms incl...

The construction of urban community sports public service is not only an important part of urban community public service management, but also an important content of building the national fitness public service system. In this paper, the author analyse the comparison between China and UK of the construction of city community sports service system in the scope of eco-civilization. With the rapi...

BACKGROUND Although a number of environmental and policy interventions to promote physical activity are being widely used, there is sparse systematic information on the most effective approaches to guide population-wide interventions. METHODS We reviewed studies that addressed the following environmental and policy strategies to promote physical activity: community-scale urban design and land...
