Otter habitat suitability
WebTheir aquatic habitats can be both marine and fresh water: streams, rivers, lakes, ponds and marshes. They prefer unpolluted water with a minimal human disturbance. An extremely adaptable animal, otters tolerate hot and cold climates, as well as high elevations and lowland coastal waters. Communication WebThe models are based on suitability indices formulated for variables found to affect the llfe cycle and survlval of each species. The models are designed to be modified to evaluate specific habitat alterations using the HSI model building techniques presented in the U. S. Fish and Wildlife Service's Habitat Evaluation Procedures. Notes:

Webefficient conservation policies. Habitat suitability models (HSM) predict species' potential distribu-tions, but the quality of their predictions should be carefully assessed when the species-environment equilibrium assumption is violated. 2.

There are 13 species of otter worldwide although only the European otter (Lutra lutra L.) is native to Britain (Mason and Macdonald, 1986). The diet of otter varies but fish generally comprise WebSea otter occurrence in nearshore marine habitats depends on depth and slope, substrate composition, prey abundance and primary productivity, coastal geography, and sea otter …
WebHabitat suitability assessments can reduce this uncertainty by identifying areas of unoc-cupied habitats that are likely to sustain the intro-duced species and foster population growth over time (Cheyne 2006). Predator populations and popu-lation growth are often limited by prey availability. Therefore, habitat models can be used to identify and WebHabitat suitability criteria were developed for seven species of unionid mussels. Amblema plicata, Fusconaia flava, Lasmigona costata, and Strophitus undulatus all had similar preferences for velocity, depth, substrate, and cover. Velocities most preferred were about 80 cm/s with velocities < 25 cm/s having no suitability.
