Climate-driven species redistribution in marine systems by Gretta Pecl of the Institute for Marine and Antarctic Studies and Centre for Marine Socioecology in Hobart, Tasmania, Australia
Climate change is driving a pervasive global redistribution of the planet’s species, with manifest implications from genes to ecosystems across multiple temporal and spatial scales. Species redistribution defies current approaches to natural resource management that focus on restoring systems to a baseline and are often based on boundaries drawn in the past. Changes in distribution of marine resources creates difficulties, particularly when species cross jurisdictional boundaries and where historical catch rates and assessment processes may no longer be appropriate. Moreover, we are still a long way from understanding the suite of mechanisms and processes underlying the high variation in rate and magnitude of shifts. We have even less understanding of how species redistribution will drive changes in ecological communities and further complicate aspirations of ecosystem-based management. Climate-driven species redistribution therefore presents intriguing ecological challenges to unravel, as well as fundamental philosophical questions and urgent issues related to ecology, fisheries, food security, Indigenous and local livelihoods, and many other aspects of human well-being. This presentation will highlight some of the progress with adaptation planning and adaptation actions at international, national and local scales, including the need for an interdisciplinary approach and stakeholder engagement.
