Dear colleagues, We are delighted to announce our upcoming Workshop on Animal Movement Analysis in the Marine Environment: https://marcfer3.wixsite.com/website When and where: 19–23 May 2025 in Funchal, Madeira Island (Portugal). A remarkable team of researchers—John Fieberg, Marie Auger-Méthé, Brett McClintock, and Inês Silva—will lead this event, focusing on the unique challenges of studying marine species and offering practical solutions to overcome data complexities. This represents an excellent opportunity for those working with satellite telemetry/biologging data from marine mammals. During the workshop, we will tackle some of the most common issues when dealing with data collected during tag deployments in marine mammals, such as data autocorrelation, data missingness, location errors and irregular sampling intervals. This hands-on training will equip researchers with tools to predict and analyse animal movements more accurately and gain insights into habitat use. By the end of the course, participants should: *Be able to clean and organise data collected by satellite tags *Apply state-space models to correct Argos location data (mainly used to track marine animals) *Apply Hidden Markov Models to infer behaviours from telemetry data *Understand the benefits and limitations of Resource Selection Functions and Step Selection Functions to infer habitat use and preferences. *Apply continuous time models to infer space use, taking into consideration autocorrelation and the irregular sampling intervals typical in marine mammals tracking data We look forward to welcoming you to Madeira in May 2025!
