In recent years, the "forest-specialist" pine marten Martes martes has been reported to also occur also in largely fragmented, lowland landscapes of north-western Italy. The colonization of such an apparently unsuitable area provided the opportunity for investigating pine marten ecological requirements and predicting its potential south- and eastwards expansion. We collected available pine mart...

Connecting isolated patches of habitat in fragmented landscapes with corridors is a popular conservation strategy. This strategy is also controversial in large part because of uncertainty about what characteristics of a species and its environment promote corridor use. In this article we address the question, For what types of species will populations benefit from corridors? We asked this quest...

Achieving global conservation goals requires that realizations, agreements, and directives be customized to reach all levels. In the context of Convention on Biological Diversity, this means approaches conserving biological diversity must developed at local landscape level support national implementation Convention. The main objective paper was review basic role in biodiversity. To achieve goal...

Streams and forests are ecosystems connected through hydrology, but few studies have looked at the connectivity between streams in context of urban development. City-made decisions affect connections by isolating both ecosystems. often channelized or buried to increase potential development areas. Forests become fragmented may be removed unless protected. Historical choices land usage sites siz...

Riparian corridors and fencerows are hypothesized to increase the persistence of forest animals in fragmented landscapes by facilitating movement among suitable habitat patches. This function may be critically important for forest birds, which have declined dramatically in fragmented habitats. Unfortunately, direct evidence of corridor use has been difficult to collect at landscape scales and t...

Urban environments present unique challenges for landscape designers wishing to incorporate wildlife attractants into their designs. Cities such as Tucson, Arizona that are surrounded by relatively large expanses of native vegetation provide many opportunities for effectively enticing native wildlife into urban spaces. Patches of landscape can be designed that mimic vegetation composition found...

Gray wolf populations have been rebounding in the Great Lakes region, after being nearly extirpated from the conterminous United States. Breeding populations of wolves have established in the Upper Peninsula of Michigan but have not yet become widely established in the Lower Peninsula (LP) of Michigan, despite several sightings of wolves in the LP since 2004. The objective of this analysis was ...

JOHNSON, BRENDA LYNN. The Effects of Habitat Fragmentation and Connectivity on Plant Disease. (Under the direction of Nick M. Haddad.) Within a large-scale habitat corridor experiment, I performed both experimental and observational studies to determine the effects of habitat fragmentation, habitat edge, and patch connectivity on the movement and incidence of fungal plant diseases. Increased sp...

Abstract Accelerated urbanization and population growth lead to the fragmentation of urban green space loss biodiversity. There are few studies on integration structural functional connectivity solve this problem. Our study aims draw up a methodology synthesize two methods evaluation, accordingly, construct an infrastructure (UGI) network which is great significance maintain stability ecosystem...

H abitat loss and fragmentation are among the most pervasive threats to the conservation of biological diversity (Wilcove et al. 1986, Wilcox and Murphy 1985). Habitat fragmentation often leads to the isolation of small populations, which have higher extinction rates (e.g., Pimmetal. 1988). Ultimately, the processes of isolation and population extinction lead to a reduction in biological divers...
