Landscape Ecology
Landscape Ecology Landscape ecology, as the name implies, is the study of landscapes; specifically, the study of landscape patterns, the interactions among the elements of pattern, how patterns and interactions change over time, and the application of these principles in the formulation and solving of real-world problems. Thus, landscape ecology is defined best by its focus on spatial heterogeneity and pattern; specifically, how to characterize it, where it comes from, why it matters, how it changes through time, and how we manage it. Landscapes are spatially heterogeneous geographic areas characterized by diverse interacting patches or ecosystems, ranging from relatively natural terrestrial and aquatic systems such as forests, grasslands and lakes to human-dominated environments including agricultural and urban settings. The most salient characteristics of landscape ecology are its emphasis on the relationship among pattern, process and scale and its focus on broad-scale ecological and environmental issues. These necessitate the coupling between biophysical and socioeconomic sciences. Key research topics in landscape ecology include ecological flows in landscape mosaics, land use and land cover change, scaling, relating landscape pattern analysis with ecological processes, and landscape conservation and sustainability. • the spatial pattern or structure of landscapes, ranging from wilderness to cities,
• Landscape: It is an area that consists of more than one ecosystem. • Ecosystem: A group of various populations in one area and their interactions among each other and with their environment. • Heterogeneity: A landscape with many different ecological patterns and structures. • Pattern: The ordered contents of a landscape. • Structure: It is the definition of the size and distribution of pattern. • Scale: It is the representation of actual distances and/or time frame of events. • Patch: A homogeneous area different from other areas around it. A patch is the lowest ranked unit of a landscape. • Mosaic: It is a series of patches connected together directly or via corridors. • Corridor: A particular kind of patch connecting two separate patches. • Edge: In ecology, an edge is the area on the perimeter of a patch. • Boundary: The area including the edges of two adjacent, intersecting patches. • Disturbance: It is an event that alters the process of change or stability of a patch or a mosaic of patches. • Fragmentation: The cutting and breaking up of a large patch into many smaller ones separated by a new and different kind of patch. Landscape Ecology is not really an independent self sufficient field of science. It is a multidisciplinary field within ecology, geography, forestry, agriculture, urban development and the new field of eco-tourism.
