Comprehensive Assessment of the Impacts of Hypoxia Guides Management and Research Priorities
A special issue of the Journal of Experimental Marine Biology and Ecology represents the most comprehensive state-of-knowledge on the impacts of hypoxia to living resources to date. A common theme throughout the 20 research articles is the frequency of chronic, sub-lethal impacts of hypoxia on living resources, such as reduced reproductive output and altered behavior.
Other topics addressed include a wide range of impacts, from molecular and physiological responses to regional and long-term changes in species distribution and composition. Additional topics include a scientific explanation of the development of dissolved oxygen criteria in the Chesapeake Bay in an effort to improve fisheries management and novel approaches and perspectives for modeling hypoxia impacts.
Research needs indentified in the special issue have provided the foundation for strategic planning of NCCOS-sponsored hypoxia programs and will directly inform research priorities in future funding announcements. In addition, findings in the special issue have reinforced the efforts of regional hypoxia management entities, such as the Mississippi River/Gulf of Mexico Watershed Nutrient Task Force, in their efforts to reduce nutrient inputs and mitigate hypoxia.
The special issue publication is the culmination of a multi-year effort to that was initiated by an NCCOS-sponsored workshop and symposium in 2007, Ecological Impacts of Hypoxia on Living Resources, held in Bay St. Louis, MS.
