The urban landscape is highly altered by human activities and is a mosaic of different land covers and land uses. Imbedded in this are forest patches of different origins (Zipperer et al .• 1997). How these patches influence and are influenced by the urban landscape is of ecological importance when managing the urban forest for ecosystem goods and services. To evaluate how forests respond to al...

Urbanization has profound influences on ecological communities, but our understanding of causal mechanisms is limited by a lack of attention to its component stressors. Published research suggests that at landscape scales, habitat loss and fragmentation are the major drivers of community change, whereas at local scales, human activity and vegetation management are the primary stressors. Little ...

Bunn, Urban and Keitt[12] discuss landscape connectivity in the Coastal Plain of North Carolina through a graph theoretic approach using focal-species analysis. Graph Theory is very much useful in the study of landscape connectivity using graph as an ecological construct. Different nodes (vertices) represent habitat patches and edges, the distance (functional distance and not Euclidean distance...

Urban park is an important component of urban public green space which provides leisure, recreation, activity place, etc. Urban park service quality was evaluated by quantitative method in this paper to provide scientific evidence for renewal and development of urban park. 5 urban parks in Xinxiang, Henan province, China were selected as evaluation samples, and 13 indexes were evaluated, includ...

  The study seeks to address the importance of urban stream ecosystems from the perspective of urban ecology, human health and social well-being in the context of urban planning. The case study area is Paveh stream in the City of Paveh. The data from the case study area were gathered from questionnaire, existing scientific and library studies and by conducting interviews with residents and auth...

tehran the capital city of iran, with a population of about 8 million and an area of over 700 km2 is one of the most polluted metropolises in the world. tehran is suffering from a tremendous reduction in its sink capacity for absorption and assimilation of pollution which is generally due to uncontrolled urban sprawl and failure in consideration of ecological aspects into regional land use plan...

Green infrastructure ameliorates the urban heat island effect, contributes positively to liveability and enables sustainability in higher density urban environments. Greenskins (living architectures) are a more specific form of green infrastructure, including green walls and green roofs, for dense urban areas. These offer a new approach for sustainable urban biophilia and some forms can be buil...

The urban transformation of the planet has spurred interest across a wide variety of disciplines in the fundamental changes to human society and the environment that result from urbanization. Landscape ecology is no exception. Since the late 1980s, the number of papers devoted to the study of the ecology of urban landscapes has risen dramatically. This trend prompted the question I address in t...

In press: Frontiers in Ecology and Environment In a nutshell:-An encouraging trend is ecological research conducted along the urban-rural gradient.-But, clear definitions and quantitative metrics are needed to place research more precisely within the landscape context.-Ecologists should measure the degree of human modification by metrics that capture important ecological processes and land use/...
