Habitat analysis using landscape metrics can be efficient in better management of habitat. As a critically endangered subspecies, the Baluchistan black bear is scattered in the Bahr Asman and Zaryab areas in Kerman province. The purpose of this study was to model the distribution of the sub-species and evaluate the quality of its habitat patches, using landscape metrics. Distribution modeling w...

The strength and prevalence of trophic cascades, defined as positive, indirect effects of natural enemies (predatory and parasitic arthropods) on plants, is highly variable in agroecosystems. This variation may in part be due to the spatial or landscape context in which hese trophic cascades occur. In 2011 and 2012, we conducted a natural enemy exclusion experiment in soybean fields along a gra...

Development of roads through protected areas and ecological sensitive regions can have catastrophic effects on wildlife. In Iran, road construction in sensitive habitats and protected areas has been expanding during the past decades. This study focuses on the ecological impacts of Isfahan’s west ringway, which passes through Ghamishloo wildlife refuge, I.U.C.N category IV, in Isfahan Province. ...

The primary approach used to conserve tropical biodiversity is in the establishment of protected areas. However, many tropical nature reserves are performing poorly and interventions in the broader landscape may be essential for conserving biodiversity both within reserves and at large. Between October 2010 and 2012, we conducted bird surveys in and around a recently established nature reserve ...

Anthropogenic landscape alteration is rather common in many protected areas (PAs), jeopardizing the efficacy of PAs conservation. However, the general consensus is that PAs still remain effective in habitat conservation. To assess the efficacy of landscape-level conservation, we examined landscape alterations in the Changbai Mountain Biosphere Reserve (CMBR), which was established in 1960 as a ...

Today, most wild tigers live in small, isolated Protected Areas within human dominated landscapes in the Indian subcontinent. Future survival of tigers depends on increasing local population size, as well as maintaining connectivity between populations. While significant conservation effort has been invested in increasing tiger population size, few initiatives have focused on landscape-level co...

Conserving animals beyond protected areas is critical because even the largest reserves may be too small to maintain viable populations for many wide-ranging species. Identification of landscape features that will promote persistence of a diverse array of species is a high priority, particularly, for protected areas that reside in regions of otherwise extensive habitat loss. This is the case fo...

this study investigates the application of landscape ecology in planning and design of urban ecological systems. the ecological approach to landscape planning and the concepts of designing and implementing ecological systems have gained increasing attention in the last two decades. however, the ecological systems of urban environment need more research to consider built and natural patches and ...
