Optimizing Marine Protected Area Networks: The effects of climate change on larval dispersal and connectivity [Wed. April 20]

A changing climate will make the conservation of marine biodiversity increasingly difficult as policies designed for current climatic conditions may not reflect those in the future. Larval dispersal and movements among populations is a crucial factor in planning networks of Marine Protected Areas (MPA) as it greatly affects population persistence and recovery. I will present some of my work quantifying larval behavior in the laboratory, to using a biophysical larval dispersal model (ROMS/LTRANS, etc) to identify patterns of larval connectivity in the present and future climate scenarios. Identifying mechanisms that drive larval dispersal and connectivity, quantifying their sensitivity to climate change, and incorporating this into planning strategies are key to developing networks of MPAs which have sound design principles that consider population connectivity and are more robust to the effects of climate change.

Join us for our March 11th Roundtable with Dr. Allison Bidlack from the Alaska Coastal Rainforest Center!

The north Pacific coastal temperate rainforest (PCTR) ecosystem extends from central British Columbia to southcentral Alaska, includes the largest remaining old-growth forests in North America, supports some of the most robust fisheries on the continent, and is home to tens of thousands of people who depend on a resource and tourism-based economy for their livelihoods. It is also a region characterized by an intricate geologic and evolutionary past, a rich cultural history, and complex linkages among ecosystem components. The social-ecological systems of the PCTR are being transformed by climate change, as well as by global economic drivers such as tourism, energy prices, and timber demand.  Given the current rates of ecosystem change and the potential for profound systemic shifts and economic upheaval in the region and beyond, a more holistic understanding of these patterns, processes and impacts is essential for the effective management of resources and the resilience of communities. This talk will provide a brief introduction to the region and some of the integrative work being performed, with an emphasis on regional projects involving existing datasets.
