摘要

Movement is a key process that links individuals, populations, and communities in space and time. Movement is also fundamental to many conservation strategies aimed at mitigating the effects of land-use change, climate change, and invasive species management. In recent years, the field of movement ecology has emerged to unite a wide range of perspectives and approaches to understand and quantify movement. Here, we provide an overview of the different types of movement that have been of interest to ecology and conservation, illustrate recent developments in understanding movement trajectories and dispersal, one key type of movement that links movement to fitness, and highlight advances that link movement to resource selection. We provide an example with the GPS-tracking and mark-resighting data on the endangered Everglade snail kite (Rostrhamus sociabilis plumbeus). Our example illustrates how to identify key changes in movement through changepoint analysis and potential behavioral states using hidden Markov models. We then illustrate the use of integrated step-selection analysis, which links movement and resource selection across landscapes. We end my illustrating how to simulate and predict movement across landscapes through the use of individual-based simulations and the calibration of landscape connectivity models with step-selection functions.
