1 Arthropod natural enemies provide valuable pest suppression in agricultural landscapes. Natural enemy abundance and diversity within a given crop, in turn, have frequently been shown to be positively related to the amount of semi-natural habitat in the landscape. However, other aspects of landscape structure may also influence natural enemy communities and may be more amenable to management. ...

Topographic metrics are designed to quantify scale-relevant relationships between geometric properties of landscapes reveal the processes shaping them. They have long been derived from topographic flow routing algorithms, initially developed for coarse Digital Elevation Models (DEMs), whose resolution (≥30 m) and poor precision did not resolve correctly patterns channel width. Since high DEMs m...

This study examines the effects of change in shape landscape patches, known as structure, on ecological susceptibility, which is defined using object-oriented method. The aim to determine whether susceptibility influenced by patches southern basin Caspian Sea. multivariate linear regression approach applied discover extent mean, median, and weighted average structure metrics can explain total v...

Often landscape metrics are not thoroughly evaluated with respect to remote sensing data characteristics, such as their behavior in relation to variation in spatial and temporal resolution, number of land cover classes or dominant land cover categories. In such circumstances, it may be difficult to ascertain whether a change in a metric is due to landscape pattern change or due to the inherent ...

Although a number of digital terrain analysis techniques were developed since the early 90ies terrain information is not utilized enough in landscape research even if topography is a key variable in a wide range of environmental processes. One explanation of this situation is the two-dimensionality of the main paradigm in landscape ecology, namely the patch-corridor-matrix model. Calculations o...
