Careful design and planning can yield robust data (e.g., discrimination, degree of exploration, numerous behaviors). This experimental apparatus can provide powerful insight into behavioral and ecological questions. Environment Integrating Remote Sensing with Species Distribution Models; Mapping Tamarisk Invasions Using the Software for Assisted Habitat Modeling (SAHM) Amanda M. West1, Paul H.

An ensemble of predictive models produced highly accurate maps of tamarisk (Tamarix spp.) invasion in Southeastern Colorado, USA when assessed with subsequent field validations.
