Habitat fragmentation seriously threatens urban biodiversity conservation and ecosystem integrity. Constructing an ecological network improving the connection level between habitat patches can effectively alleviate general environmental problems of rapid development. In this paper, three focal animal species were selected in central area Yichang City China. Based on quality assessment results I...

rangeland ecosystem contains various patches with different functions. structural and functional characteristics of rangeland patches are changed by management practices and can be used to interpret management effects. the structural and functional characteristics of fertilized patches in two rangeland ecosystems of ghareh ghir and maraveh tapeh were measured and analyzed in this study. a group...

using piezoelectric patches the stress concentration around a hole on a plate under tension is reduced and controlled. to attain the reduction in stress two placements for piezoelectric patches is investigated. the first location is top/bottom of the hole with compression induced strain and the second is left/right of the hole with tension induced strains to control the stress flow. the result ...

A comparison of 4 × 4 multiple-input multiple-output wireless local area network wireless communication characteristics for six different geometrical shapes is investigated. These six shapes include the straight shape corridor with rectangular cross section, the straight shape corridor with arched cross section, the curved shape corridor with rectangular cross section, the curved shape corridor...

Habitat connectivity is crucial for the conservation of species restricted to fragmented populations within human-dominated landscapes. However, identifying habitat apex predators challenging because trophic interactions between primary productivity and prey influence both distribution habitats, predator movement. Our goal was assess Indochinese tigers (Panthera tigris) in Thailand. We quantifi...

The Yellow River Basin serves as a crucial ecological barrier in China, emphasizing the importance of accurately examining spatial distribution forest carbon stocks and enhancing sequestration order to attain “carbon peaking neutrality”. Forest patches have complex interactions that impact ecosystem services. To our knowledge, very few studies explored connection between these stock. This study...

Logging, cattle raising, and agricultural activities have caused the destruction of most forested areas in Costa Rica. In some middle and highlands the abrupt topography delayed the complete destruction of montane forest. Consequently, some fragments of almost pristine forest remain along streams that run in deep canyons. Frequently, these remnants serve as corridors between larger forested are...

We isolated seven polymorphic microsatellite loci from a ground beetle (Bembidion atrocaeruleum, Coleoptera, Carabidae (Stephens, 1826)) associated with naturally and regularly disturbed floodplain habitat in northwest Europe. Loci were tested on 157 individuals collected from five distinct habitat patches across two adjacent drainage basins in Wales, United Kingdom, to assess their potential f...

The synchronous behaviour of interacting communities is studied in this paper. Each community is described by a tritrophic food chain model, and the communities interact through a network with arbitrary topology, composed of patches and migration corridors. The analysis of the local synchronization properties (via the master stability function approach) shows that, if only one species can migra...

Despite many studies showing that landscape corridors increase dispersal and species richness for disparate taxa, concerns persist that corridors can have unintended negative effects. In particular, some of the same mechanisms that underlie positive effects of corridors on species of conservation interest may also increase the spread and impact of antagonistic species (e.g., predators and patho...
