this study investigates the application of landscape ecology in planning and design of urban ecological systems. the ecological approach to landscape planning and the concepts of designing and implementing ecological systems have gained increasing attention in the last two decades. however, the ecological systems of urban environment need more research to consider built and natural patches and ...

I this paper, 1) a delineation of main theoretical, methodological and applicative issues of landscape ecology, 2) a comparison between landscape and ecosystem ecology, 3) a critical overview of actual limits of landscape ecology, are depicted. We conclude that: a) from a theoretical viewpoint, ecosystem and landscape ecology differ since they deal with ecological topics having very different s...

Wetlands are very sensitive to ecosystem changes, so integrated analyses and modeling of their process dynamics as well as their interaction with other hydrologic and ecological components provide valuable information for impact assessment. However, since wetland processes are complex, research methods aiming to improve the understanding of wetland dynamics in a landscape perspective must compr...

Cultural landscapes are increasingly understood as something not merely to be protected. The European Spatial Development Perspective (ESDP) and the European Landscape Convention (ELC) as well as the new Concepts and Strategies for Spatial Development in Germany propose considering cultural landscapes also as a force to promote cooperative regional development. Common historical roots, special ...

introduction the urban population experienced rapid growth in the recent decades, particularly between 1975 and 2000 when it has reached from 1.5 to more than 2 billion people. by turn of the century; half of the world's populations are concentrated in cities. this would severely affect the quality of life in urban areas. accordingly, cities will be faced with significant challenges in inf...

Nutrient acquisition is a major context for ecological interactions among species but ecologists and nutritionists have developed theory in isolation from each other. Developments in agent-based modelling, state-space modelling of nutrition and multi-scale modelling of landscape ecology provide the components for a new synthesis in nutritional ecology linking the nutritional biology of individu...

A new design framework is introduced for forest structure optimization based on a genetic algorithm landscape encoding and landscape ecology metrics. Landscape ecology is an important interface between the forest management community, which is a traditional user of operations research methods, and the biological conservation community which is relatively new to OR methods and whose goals are in...

and methodological developments by recognizing the importance of micro-, meso-, macro-, and cross-scale approaches. The term landscape ecology was coined in 1939 by the German geographer Carl Troll, who was inspired by the spatial patterning of landscapes revealed in aerial photographs and the ecosystem concept developed in 1935 by the British ecologist Arthur Tansley. Troll originally defi ned...
