Article history: Received 22 November 2005 Received in revised form 8 March 2006 Accepted 12 March 2006 In all natural populations, individuals located close to one another tend to interact more than those further apart. The extent of population viscosity can have important implications for ecological and evolutionary processes. Here we develop a spatially explicit population model to examine h...

Oasis stability in the lower reaches of the Tarim River was assessed at the landscape scale (including changes in landscape pattern and land use in the oasis) and at the regional scale (including the cold-island effect and NDVI of the oasis) based on the methods of landscape ecology, GIS and Remote Sensing (RS). Thematic Mapping (TM) remote sensing images from 1990, 2000 and 2009 were employed ...

With economic growth and the improvement of the urbanization level, human activities have constantly interfered with landscape patterns, resulting in serious threats to regional ecological security. Therefore, it is of great significance to study the evolution and optimization of the landscape patterns. Based on three TM images from 1990, 2000, and 2010, and selected landscape pattern indexes, ...

A fundamental premise of landscape ecology is that finer-scaled local ecological integrity is directly influenced by larger-scaled land use patterns. Therefore, characterizing landscape patterns that are mapped from satellite imagery may provide valuable covariate information about average integrity “on the ground”. This conjecture was evaluated in Pennsylvania for 102 watersheds where land cov...

The term “landscape structure” refers to the configuration of vegetation and other land features over a large land area (usually an extent of many square kilometers). A landscape can be regarded as a mosaic composed of patches of different kinds— for example, different forest types, landforms, or human-built structures such as roads. The scientific discipline of landscape ecology is concerned w...

In this article we compare five alternative projects for the requalification of an abandoned quarry. The starting point for this paper was a request made by a decision maker. It was not for help in making a decision as such, but rather for a comparison of different projects. In particular, we are interested in ranking the considered projects on the basis of six different criteria. An extension ...

Quantum computation has been proposed to generate consciousness. The terms atman field and consciousness vector have also been used to describe the properties of consciousness. It has also been proposed that the human activities should lead to increase in the magnitude of the consciousness vector of the universe. The universe is increasingly being seen as one system and the earth is a constitue...

Landscape ecology is an emerging branch of science, incorporating a multitude of principles and theories. Landscapes can be loosely defined as ecosystems occurring over an area in a similar form (Forman, 1995). This science includes such aspects as scale, the spatial configuration of the landscape, energy flows within the system, the boundaries, and the heterogeneity within the system (Wiens, 1...
