Title: Modelling animal movement with state-space models
Authors: Joanna Mills Flemming - Dalhousie University (Canada) [presenting]
Abstract: Animals move in order to maximize their probability of survival and reproduction. The movement of an animal therefore reflects its response to its current physical needs and available environment. In the marine realm, where direct observation of animal movements is often impossible, researchers typically employ satellite telemetry positioning systems to obtain series of estimates of locations of animals in space through time. Each series resembles an animal path or track. State-space models represent an ideal framework for accounting for both measurement error and process error in these tracks. We discuss novel formulations that allow us to model these tracks robustly and at the same time infer animal behavioral states. Information gained from these efforts is currently being used for proper management of both species and ecosystems as will be evident from the applications presented.
