Structure and Process – Influence of Historical Agriculture of Linear Flow Paths by Extreme Rainfall in Brandenburg

Long-term erosion forecast can completely misinterpret in extreme events in plain regions. Flow paths are well represented in the plain using digital elevation models in the 1-m grid (DEM1). The scale of the erosion process models and the elevation models is comparable. With it instruments are available to improve the erosion simulation. Simulations, based on (R)USLE family and bigger grid …

Geometric approaches to computing 3D-landscape metrics

The relationships between patterns and processes lie at the core of modern landscape ecology. These dependences can be quantified by using indices related to the patch-corridor-matrix model. This model conceptualizes landscapes as planar mosaics consisting of discrete patches. On the other hand, relief variability is a key factor for many ecological processes, and therefore these processes can be better modeled …

Evaluating Anthropogenic Risk of Grassland and Forest Habitat Degradation using Land-Cover Data

The effects of landscape context on habitat quality are receiving increased attention in conservation biology. The objective of this research is to demonstrate a landscape-level approach to mapping and evaluating the anthropogenic risks of grassland and forest habitat degradation by examining habitat context as defined by intensive anthropogenic land uses at multiple spatial scales. A landscape mosaic model classifies a …

Effects of topography and surface roughness in analyses of landscape structure – A proposal to modify the existing set of landscape metrics

Topography and relief variability play a key role in ecosystem functioning and structuring. However, the most commonly used concept to relate pattern to process in landscape ecology, the so-called patch-corridor-matrix model, perceives the landscape as a planimetric surface. As a consequence, landscape metrics, used as numerical descriptors of the spatial arrangement of landscape mosaics, generally do not allow for the …
