Dispersal plays a fundamental role to connect populations and determine the resilience of species to changes. However, there is still a limited knowledge about the dispersal strategies and effective population connectivity of many marine species due to the difficulty of tracking and modelling the trajectory and fate of propagules, as well as to accurately characterise the environment of connection paths. This tutorial presentation aims to provide an overview of biological connectivity topic from gene to community level in different species groups and marine environments (ocean, coast, estuaries), to infer species and ecosystem vulnerability in the face of global change. At species level, case studies encompassing gene flow among populations in heterogeneous landscapes and expected shifts in habitat suitability under climate change scenarios will be presented. At community level, the challenging task of estimating population migration rates and dispersal limitation will be overviewed. The implications of this for testing the neutral theory of biodiversity in the marine realm and for assessing species potential for acclimation and colonization new areas will be discussed.
