The relative influence of habitat loss, fragmentation and matrix heterogeneity on the viability of populations is a critical area of conservation research that remains unresolved. Using simulation modelling, we provide an analysis of the influence both patch size and patch isolation have on abundance, effective population size (N(e)) and F(ST). An individual-based, spatially explicit population...

Land fragmentation has become a serious obstacle to agricultural production, and land transfer consolidation are traditionally emphasized as the two most effective solutions this quandary. To identify extent of accurately systematically, study selected number plots, average size distance between plots calculate index (LFI). Taking Wuhan metropolitan area case study, examined effectiveness farme...

We report an analysis of forest fragmentation based on 1-km resolution land-cover maps for the globe. Measurements in analysis windows from 81 km 2 (9 x 9 pixels, “small” scale) to 59,049 km 2 (243 x 243 pixels, “large” scale) were used to characterize the fragmentation around each forested pixel. We identified six categories of fragmentation (interior, perforated, edge, transitional, patch, an...

Because agoutis (Dasyprocta sp.) and acouchies (Myoprocta sp.) are the most important dispersers of several large-seeded Amazonian trees, knowing their responses to forest fragmentation is essential and urgent. But until now, there was no study showing their population trends in Amazonian land forest fragments. The present study was conducted at the Biological Dynamics of Forest Fragments Proje...

Expansion and intensification of human land use represents the major cause of habitat fragmentation. Such fragmentation can have dramatic consequences on species richness and trophic interactions within food webs. Although the associated ecological consequences have been studied by several authors, the evolutionary effects on interacting species have received little research attention. Using a ...

Effects of habitat fragmentation on genetic diversity vary among species. This may be attributed to the interacting effects of species traits and landscape structure. While widely distributed and abundant species are often considered less susceptible to fragmentation, this may be different if they are small sized and show limited dispersal. Under intensive land use, habitat fragmentation may re...

For poverty-stricken mountainous cities in China, both poverty alleviation and ecological restoration projects are sources of land-use change urban development. However, the patterns changes understudied light sustainable forest management. The study aims to explore characteristics a city with focus on forests. This research proposed three-step approach multi-aspect dynamics land change, includ...

The JRC demonstrated the feasibility to assess and report in a harmonized manner, forest landscape pattern and fragmentation in Europe, on the basis of an easily reproducible set of indices. Results were used in the Forest EUROPE, UN ECE and FAO joint ministerial reporting process on the protection of forests in Europe where data on forest pattern do not exist from national forest inventories. ...

Studying the differences in township gradient of rural construction land structures at microscale is beneficial for adjustment structure based on local conditions and differentiation, classification guidance scientific planning management land, improving level intensive use land. In this study, we took 268 administrative villages Yuzhong County Loess Hilly Region as research object conducted in...
