Considering the fact that fish biodiversity conservation and land uses planning, require reliable information about fish distribution and habitat use patterns In order to describe species habitat properties, habitat use and habitat selectivity indices are applied. Relative frequency and environmental variables, depth, width, slope of river, altitude, velocity, substrate, Overstream canopy closu...

Point-of-care testing is a rapidly evolving yet complex field. As your POCT program grows, take the time to understand the regulations, as they are important to ensuring patient safety. The regualtions established CLIA are designed to ensure consistent and reliable laboratory results that can accurately impact patient care. When beginning your look into POCY, first identify what labs can direct...

This paper examines and ranks restoration alternatives for improving fish habitat by evaluating tradeoffs between fish production and restoration costs. Optimization modelling is used to maximize out‐migrating coho salmon (Oncorhynchus kisutch) from a natal stream and is applied as a case study in California’s Shasta River. Restoration activities that alter flow and water temperature conditions...

An individual-based model of animal dispersal and population dynamics was used to test the effects of different climate change adaptation strategies on species range shifting ability, namely the improvement of existing habitat, restoration of low quality habitat and creation of new habitat. These strategies were implemented on a landscape typical of fragmentation in the United Kingdom using spa...

As habitats become more fragmented, understanding landscape-level effects on habitat quality becomes increasingly important. These effects include factors intrinsic to the habitat fragments, such as vegetation cover and structure, and extrinsic factors, such as the modifying influences of surrounding (matrix) habitats. We develop a spatial model, the Effective Area Model (EAM), that predicts th...

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. ...
