Workshops


Lorenzo Ciannelli held a workshop on the use of Generalized Additive Models for the analysis of fisheries data. The workshop was held at the Institute of Marine Research station in Flodevigen (Norway) from May 22-24, 2013. Fifteen people (including mostly graduate students and early career scientists) from various Universities in Norway and Denmark attended the workshop. The workshop was sponsored by NorMER and was part of the newly developed Marine Center at the University of Agder.


Sustainability of marine renewable resources in subarctic systems under incumbent environmental variability and human exploitation

Through Research Coordination Network (RCN) activities we bridge a gap among ecologists, mathematicians, social scientists and resource managers to provide a sound science support system for conservation. Our scientific goal is integrate basic eco-evolutionary and socioeconomic principles to address the consequences of current and alternative policy practices in large and commercially exploited marine ecosystems. We focus on subarctic marine systems, which are susceptible to climate variability, are highly productive but also intensely exploited, and are under-represented in socio-ecological literature. Our scientific activities are centered on three ecological themes, namely, sequential species, spatial, and demographic depletions. The educational goal of our network is to train research and management scientists in the interdisciplinary fields of ecology, oceanography, evolution, sociology and conservation. We aim to expose young scientists to the crosscutting disciplines and issues related to sustainability in marine fisheries, and to foster sustained, cross-disciplinary interactions among early and advanced career scientists at national and international institutions.

On February 11-13, 2013 we held a workshop at Oregon State University that focused on the RCN educational activities. We brought people together from different disciplines and institutions to develop a curriculum for a new summer academy that will provide a venue for students to 1) learn about marine resource sustainability from the perspectives of natural scientists, social scientists, managers, and stakeholders, 2) identify challenges of effective cross-disciplinary collaborations and explore strategies to address these barriers, and 3) carry out cross-disciplinary group projects on pertinent issues and questions related to marine resource sustainability. Most importantly, we aim to provide young scientists with an opportunity to develop sustained, cross-disciplinary interactions with peers from national and international institutions.

Our first project meeting was held on February 27-29, 2012 in Seattle, WA. This meeting brought together a diverse group of scientists (ecologists, economist, historian, social scientists, mathematical biologists) from government and academic institutions. Over the course of 3 days we made significant progress on integrating the three ecological themes of our scientific activites within a multi-disciplinary context. We also planned upcoming education and research activities and outlined a comprehensive opinion article from the meeting discussions. The next project meeting is scheduled for March 2013 in Corvallis, Oregon.

Role of predator-prey interactions in marine ecosystem organization: development of a new toolbox and a comparison of key interactions in the Bering Sea and Gulf of Alaska ecosystems

Principal Investigators: Lorenzo Ciannelli, Kevin Bailey, Kung-Sik Chan and Kerim Aydin

Post-Docs and Students: Mary Hunsicker, Kun Chen and Clint Leach

Several of our CAMEO funded projects have reached completion and some are still ongoing. A list of our CAMEO-related publications is presented below. In addition to this work, we hosted a CAMEO-funded workshop on predator-prey interactions in marine ecosystems at OSU. The workshop focused on examining methods of scaling up from local observations, shifting processes as scale changes, and complexity and organizational structure in predator-prey interactions. Two papers stemmed from the workshop (Baily et al. 2010, Hunsicker et al. 2011). Attendees included national and international experts in predator-prey interactions, fish ecology, ecosystems, ecology, statistics, behavior, and modeling. See a photo of workshop attendees.
