The establishment of ecological networks facilitates genetic exchange among species in national parks and is an effective means avoiding habitat fragmentation. Using the proposed “Ailaoshan-Wuliangshan” Yunnan Province, China, as study area, identification source sites using morphological spatial pattern analysis (MSPA) method, extraction potential corridors minimum resistance model (MCR) const...

Habitat fragmentation affects the survival of wildlife and is a main threat to biodiversity. Corridors are frequently used alleviate habitat fragmentation. However, corridors costly often ineffective in practice. Endangered species montane regions particularly affected by therefore require economic efficient conservation strategies. We propose stepping stone strategy (SSS) deal with threatening...

Editorial Corridors and Towers When C P Snow wrote "The Corridors of Power" he sought to demonstrate the inner workings of the political process in Whitehall. Now that we are coming towards the end of the useful life of the building known as the "RVH corridor" it is time to consider some of the inner workings of our own profession. Wards 1-20 in the Royal Victoria Hospital represent only a smal...

The Japanese National Biodiversity Strategy 2010 calls for the creation of ecological networks as a biodiversity conservation policy. This study proposed a plan of ecological networks to conserve two threatened local populations of Asiatic black bear (Ursus thibetanus japonicus) in Fuji and Tanzawa region in Japan with the support of GIS technologies. Using the predicted habitat patches of bear...

Changes in climate and rapid urbanization have aggravated the urban heat island effect, a reasonable means to reduce temperature increases surface thermal environment is urgently needed. We integrated research perspectives of patch network, taking Yinchuan metropolitan region as area, reduced through rational allocation ecological land. For patch, correlation analysis linear regression were use...

Monarch butterflies (Danaus plexippus) depend on the presence of host plants (Asclepias spp.) within their breeding range for reproduction. In the southern Great Plains, Asclepias viridis is a perennial that flowers in May and June, and starts to senesce by August. It is locally abundant and readily used by monarchs as a host plant. We evaluated the effects of summer prescribed fire on A. virid...

The radiation range of the corridor effect holds great significance for ecological restoration, planning, and sustainable development river corridors. This study focuses on Beijing plain section Yongding River, which has been cut off half a century, improves research methodology. Utilizing land use data from 1967 1980, ArcGIS Fragstats were employed to establish 5 km buffer zones both sides Riv...

In sub-Saharan Africa, dozens of major "development corridors" have been proposed or are being created to increase agricultural production [1-4], mineral exports [5-7], and economic integration. The corridors involve large-scale expansion of infrastructure such as roads, railroads, pipelines, and port facilities and will open up extensive areas of land to new environmental pressures [1, 4, 8]. ...
