Climate vulnerability and resilience in the most valuable North American fishery

Climate change is impacting global fisheries and societies that depend on them. Identifying climate adaptation measures requires understanding of how environmental changes and management policies interact in driving fishery productivity. Coincident with the recent exceptional warming of the northwest Atlantic Ocean and removal of large predatory fish, the American lobster has become the most valuable fishery resource in North America. A new PNAS paper by Arnault Le Bris et al. shows that interactions between warming waters, ecosystem changes, and differences in conservation efforts led to the simultaneous collapse of the lobster fishery in southern New England and record-breaking landings in the Gulf of Maine. The results demonstrate that sound, widely adopted fishery conservation measures based on fundamental biological principles can help capitalize on gains and mitigate losses caused by global climate change.

Global Change in Marine Systems: Societal and Governing Responses – a new publication by the IMBeR Human Dimensions Working Group (HDWG)

Marine social and ecological systems are facing multiple challenges due to global change. The IMBeR Human Dimensions Working Group’s recently published book “Global Change in Marine Systems: Societal and Governing Responses”, examines some of the actions taken in response to an environmental or other impact resulting from global change in 20 case studies from a range of marine systems around the world. The "I-ADApT" analytical decision support tool developed by the HDWG to help decision makers consider possible responses to global change, based on experiences elsewhere was applied to the case studies. Assessment of the societal and governing responses, highlighted similarities and differences between “the good, the bad and the ugly” - successful, and less successful, responses. Beth Fulton says “…This is the kind of go-to guide that will see us jump from simply identifying problems to doing something about it and finding our way to robust solutions." Rosemary Ommer: “While emphasizing on the importance of in-depth disciplinary perspectives, it also applies an innovative framework for cross-disciplinary analysis, which the governability of these systems requires. Thus, the book has important lessons for policy makers, management practitioners and academics alike." Read the full reviews here

New IMBeR Scientific Steering Committee members

IMBeR is very pleased to welcome the following new members who have just joined its Scientific Steering Committee: Chris Cvitanovic (Early Career Rep.), Oscar Iribarne, Olav Sigurd Kjesbu, Frank Muller-Karger, Alice Newton, Suvaluck Satumanatpan, and David VanderZwaag. They come to IMBeR from an array of marine disciplines with wide and varied research interests, and a staggering amount of expertise and experience!

We would also like to take this opportunity to thank Alida Bundy, Ratana Chuenpagdee, Masao Ischii, Tatiana Rynearson and Svein Sundby who are rotating off, for their amazing contributions to IMBeR over the years that they served on the SSC.

Climate-driven changes in functional biogeography of Arctic marine fish communities

The distribution of fish species in the Barents Sea is changing due to increasing temperatures and reduced sea ice cover. We were eager to know if shifts in species composition and distribution are also reflected in changes in ecosystem functioning, i.e., in the way important biological and biogeochemical processes work. The warmer temperatures and reduction in sea ice coverage are rapidly altering how marine communities function in the Barents Sea. The rapid changes in functional characteristics of Arctic communities indicate that it is not only the species that are changing, as previous studies had shown, but the way the ecosystem functions is also changing. The functional characteristics associated with warmer boreal fish species are quickly replacing the functional characteristics associated with the colder Arctic fish species. Boreal and Arctic communities each previously covered about 50% of the Barents Sea, but the Arctic communities were reduced to 20% of the region during the recent warming period.

The 2016-2025 IMBeR Science Plan and Implementation Strategy has been ratified!

After an intensive consultation and review process that began in 2012, the IMBeR Science Plan and Implementation Strategy (SPIS) has now been sanctioned by IMBeR’s sponsors – the Scientific Committee on Oceanic Research (SCOR) and Future Earth. The SPIS outlines IMBeR´s research agenda until 2025, towards its vision of Ocean sustainability under global change for the benefit of society.
