Over the past decade, rapid landscape pattern change has taken place in many arid and semi-arid regions of China, such as the Yellow River Basin. In this paper, landscape evolution was investigated by the combined use of satellite remote sensing, geographic information system (GIS) and landscape modelling technologies. The aim was to improve our understanding of landscape changes so that sustai...

Contemporary landscapes are subject to a multitude of human-derived stressors. Effects of such stressors are increasingly realized by population declines and large-scale extirpation of taxa worldwide. Most notably, cumulative effects of climate and landscape change can limit species' local adaptation and dispersal capabilities, thereby reducing realized niche space and range extent. Resolving t...

With accelerated deforestation and fragmentation through the tropics, assessing the impact that landscape spatial changes may have on biodiversity is paramount, as this information is required to design and implement effective management and conservation plans. Primates are expected to be particularly dependent on the landscape context; yet, our understanding on this topic is limited as the maj...

How is gradual landscape change perceived and dealt with at the community level? Based on a case study approach, this question is investigated with regards to agricultural abandonment and the subsequent expansion of forests in the Black Forest, Germany. In the case presented, local residents’ perception of incremental landscape change does not correspond with a survey on biophysical features of...

Urbanization brings biophysical changes in the composition of the landscape. Such change has an impact on the thermal environment locally. The urban mosaic of land use and land cover is thus characteristically composed of local climate zones. The spatial variation in the land surface temperature across specific zone is studied for Bhopal city. The objective of the study was to understand how th...

Development of roads through protected areas and ecological sensitive regions can have catastrophic effects on wildlife. In Iran, road construction in sensitive habitats and protected areas has been expanding during the past decades. This study focuses on the ecological impacts of Isfahan’s west ringway, which passes through Ghamishloo wildlife refuge, I.U.C.N category IV, in Isfahan Province. ...

© The Ecological Society of America www.frontiersinecology.org T interplay between fine-scale patterns and processes and broad-scale dynamics is increasingly being recognized as key to understanding ecosystem dynamics, particularly as the number and magnitude of global change drivers increases over time (Huston 1999; Rodó et al. 2002; King et al. 2004). Cross-scale interactions (CSI) are proces...

a r t i c l e i n f o JEL classification: R14 R52 Keywords: R14 Land use patterns R52 Land use and other regulations This paper expands empirical testing of the predictions of the standard monocentric urban model to examine the size of urban spatial expansion for all US metropolitan regions for the years 1980, 1990 and 2000. Until recently, the lack of temporally and spatially-consistently inte...

Succession provides a temporal framework in which to understand ecological processes. Studies of community assembly and changes in species diversity and nutrient cycling, for example, benefit greatly from the temporal perspective that succession offers. The temporal consequences of species interactions throughout the life history of each species are also well integrated into the conceptual fram...
