background: scorpions’ stings and their own mortalities place them among the most important health and medical problems. the dreadful features and especially their poisonous stings are considered a major cause of human stress and abhorrence/phobia. the current study aimed to study the scorpion fauna of ilam province, south western iran in order to manage scorpionism related problems. methods: i...

The geographic distribution of stream reaches with potential to support high-quality habitat for salmonids has bearing on the actual status of habitats and populations over broad spatial extents. As part of the Coastal Landscape Analysis and Modeling Study (CLAMS), we examined how salmon-habitat potential was distributed relative to current and future (+100 years) landscape characteristics in t...

Ailanthus altissima (tree of heaven), Simaroubaceae, is an early successional tree, native to China and North Vietnam, which has become invasive in Europe and on all other continents except Antarctica. It is most abundant in urban habitats and along transportation corridors, but can also invade natural habitats. This paper reviews the literature on the morphology, distribution, ecology, habitat...

ABSTRACT We developed a scheduling model (LMSCHED) that incorporates stream sediment and stream temperature goals into a forest planning process, allowing one to both evaluate the levels of these measures of aquatic habitat, and to set constraints regarding their upper limit. The scheduling model uses tabu search to identify feasible forest plans with respect to goals and constraints that are s...

The main aim of this study is to investigate the suitability of 1) combining map data derived from the Landsat satellite and other sources with statistical methods for analyzing habitat selection and making probability maps for large areas, and 2) testing a sampling design where volunteers arbitrarily select a walking route within specific areas for conducting transects surveys of wildlife. We ...

Declines in avian populations highlight a need for rigorous, broad-scale monitoring programs to document trends in avian populations that occur in low densities across expansive landscapes. Accounting for the spatial variation and variation in detection probability inherent to monitoring programs is thought to be effort-intensive and timeconsuming. We determined the feasibility of the analytica...
