Landscape ecology is maturing as both a traditional natural science and an integrative field. It strives to meet the demands of traditional science through incremental scientific achievements realized via experimentation and hypothesis testing, while working at scales not conducive to the paradigm of controlled experiments. At the same time, landscape ecology is the intersection of many older s...
Sewall Wright’s adaptive landscape is the most influential heuristic in evolutionary biology. Wright’s biographer, Provine, criticized Wright’s adaptive landscape, claiming that its heuristic value is dubious because of deep flaws. Ruse has defended Wright against Provine. Ruse claims Provine has not shown Wright’s use of the landscape is flawed, and that, even if it were, it is heuristically v...
This paper presents the creation of a a visual environment for exploring landscape patterns and changes to such patterns over time. Dynamic landscape patterns can involve both spatial and temporal complexity. Exploration of spatio-temporal landscape patterns should provide the ability to view information at di erent scales to permit navigation of a vast amount of information in a manner that fa...
As mentioned above, since the beginning of the 1980 s , Naveh has widened the horizon of his studies from Mediterranean to global issues of landscape ecology and sustainability. One of his first major studies, and also the first paper in the English language dealing at length with landscape ecology, was published in "Advances in Ecological Research, 1982" This piece was a response to a critical...
Metrics that quantify habitat connectivity and fragmentation in landscape ecology are examined, as well as the relations between them and their interpretation. The radius of gyration, defined here as the root-mean-square distance of habitat patches from the center of the habitat, has special significance from an ecological point of view that other metrics lack. This metric has been incorrectly ...
Cities are home to more than half of the world population. Cities have been the centers of economic and social developments, as well as sources of many major environmental problems. Cities are created and maintained by the most intense form of human-nature interactions. Cities are spatially extended, complex adaptive systems—which we call landscapes. The future of humanity will increasingly rel...
This publication introduces the concepts and principles of landscape ecology for managing wildlife and other natural resources. It is intended to raise public awareness and give an overview of a new philosophy and method for managing natural resources at the landscape level. A landscape is a heterogenous area composed of a cluster of interacting ecosystems that are repeated in various sizes, sh...

The only thing about Nature that is certain and absolute is patchiness in space and time. All landscapes are patchy over a range of scales as consequences of natural and anthropogenic processes. To understand the dynamics of hierarchically structured, heterogeneous systems, models are important in several ways. Models can be used to generate new hypotheses, to clarify and test existing hypothes...
The understanding of landscape controls on the natural variability of hydrologic processes is an important research question of the PUB (Predictions in Ungauged Basins) initiative. Quantitative landscape ecology, which aims at understanding the relationships of patterns and processes in dynamic heterogeneous landscapes, may greatly 5 contribute to this research effort by assisting the coupling ...
