Biological invasions and land-use changes are two major causes of the global modifications of biodiversity. Habitat suitability models are the tools of choice to predict potential distributions of invasive species. Although land-use is a key driver of alien species invasions, it is often assumed that land-use is constant in time. Here we combine historical and present day information, to evalua...

quantification of the habitat available for fish species named rainbow trout (oncorhynchusmykiss) were evaluated in lees ferry, colorado river using water depth, water temperature, sediment transport,flow velocity in 2004 as environmental index. for the flow velocity and temperature distribution calculationsin the river, the navier-stokes equation and energy conservation equations with finite v...

isfahan wild sheep ovis orientalis isphahanica is listed as vulnerable in the iucn red list of threatened species. adequate knowledge on habitat requirements and environmental factors determining the niche of a species is central to its conservation programmes. however, there is scarcity of data on habitat associations of this species in iran. a gis-based model, using presence-only data, was us...

In this paper we present work in progress for developing a semantic modeling system for wildlife monitoring, management and conservation. Based on a Greek NGO experience in large carnivores conservation in the mountain ecosystems of northern Greece, we present a generic architecture for wildlife information fusion, sharing and reuse. Our framework employs ontologies for representing the key dom...

A fundamental step in conserving biodiversity is identification of quality habitat needed to sustain populations of target species. We used coarse scale environmental features (soil water holding capacity, soil texture, slope, elevation, and proximity to drainage channels) to predict habitat suitability for four species of desert amphibians in Big Bend National Park, USA: Scaphiopus couchii, Bu...

this study was conducted in dez and karkheh regions in southwestern iran to model habitatsuitability of the persian fallow deer dama dama mesopotamicus and assessing trend of habitat changes since1989. a total of 22 confirmed presence records of the species were collected from 1988 to 2003. maxentapproach was used to develop habitat suitability model with regards to nine environmental variables...
