Summary 1 The concept of the ecological niche relates a set of environmental variables to
the fitness of species, while habitat suitability models (HSMs) relate environmental variables …

Human land use has modified the structure and function of terrestrial landscapes throughout
much of the world, with cropping and livestock grazing the major drivers of landscape …

This paper examines the usage and measurement of “landscape connectivity” in 33 recent
studies. Connectivity is defined as the degree to which a landscape facilitates or impedes …

Traditional approaches to the study of fragmented landscapes invoke an island-ocean
model and assume that the nonhabitat matrix surrounding remnant patches is uniform. Patch …

While most efforts at biodiversity conservation have focused primarily on protected areas
and reserves, the unprotected lands surrounding those area—the" matrix"—are equally …

Habitat loss and degradation that comes as a result of human activity is the single biggest
threat to biodiversity in the world today. Habitat Fragmentation and Landscape Change is a …

Many indicators and criteria have been proposed to assess the sustainable management of
forests but their scientific validity remains uncertain. Because the effects of forest …

Within mosaic landscapes, many organisms depend on attributes of the environment that
operate over scales ranging from a single habitat patch to the entire landscape. One such …

We report a multiple-scale analysis of forest fragmentation based on 30-m (0.09 ha pixel− 1)
land-cover maps for the conterminous United States. Each 0.09-ha unit of forest was …

Habitat isolation can affect the distribution and abundance of wildlife, but it is an ambiguous
attribute to measure. Presumably, isolation is a characteristic of a habitat patch that reflects …
