A mosaic of intact native and human-modified vegetation use can provide important habitat for top predators such as the puma (Puma concolor), avoiding negative effects on other species and ecological processes due to cascade trophic interactions. This study investigates the effects of restoration scenarios on the puma's habitat suitability in the most developed Brazilian region (São Paulo State...

The Survey of the ecological characteristics of the species and determining their habitat suitability is one of the main principles of management and conservation of wildlife species. Hence, we need methods that can help assess habitats and can estimate, over time, reduce of their quality. To understand the effects of human activities and the changes of a habitat, it is necessary to make quanti...

Regional scale habitat suitability models provide finer scale resolution and more focused predictions of where organisms may occur. Previous modelling approaches have focused primarily on local and/or global scales, while regional scale models have been relatively few. In this study, regional scale predictive habitat models are presented for deep-sea corals for the U.S. West Coast (California, ...

Abstract Mangroves are potential habitats for diverse waterbirds, and its preys, but mangroves conversion caused variations of mangrove forests area along the northern coast Situbondo Regency. Therefore, it is important to analyze interaction area, diversity prey The waterbirds density observed by points count method transect in six stations, namely Banyuputih, Mangaran, Panarukan, Kendit, Subo...

Forest management often has cumulative, long-lasting effects on wildlife habitat suitability and the effects may be impractical to evaluate using landscape-scale field experiments. To understand such effects, we linked a spatially explicit landscape disturbance and succession model (LANDIS) with habitat suitability index (HSI) models to assess the effects of management alternatives on habitat s...

Environmental heterogeneity affects not only the distribution of a species but also its local abundance. High heterogeneity due to habitat alteration and fragmentation can influence the realized niche of a species, lowering habitat suitability as well as reducing local abundance. We investigate whether a relationship exists between habitat suitability and abundance and whether both are affected...

Introduction: Rangelands constitute almost 52 percent of the country area computed as 164 million ha. The extent of rangelands has been estimated 84 million ha in Iran and they have been classified as good, moderate to poor and poor to very poor ones ranged as almost 10, 42 and 48 percent, respectively. One of the fundamental problems concerning land uses of rangelands is that Rangeland are not...
