Aseries of prominent and controversial papers about the state of marine ecosystems has occupied the pages of high-profile journals over the last decade [1–7]. While some might quarrel with the specific conclusions of these papers, there is no dispute that managers of ocean and coastal habitats confront a growing diversity of very serious challenges [8](More)
In an effort to accelerate the ongoing paradigm shift in fi sheries science from the traditional single-species mindset toward more ecosystem-based approaches, we offer the following “commandments” as action items for bridging the gap between general principles and specifi c methodologies. 1. Keep a perspective that is holistic, risk-averse, and adaptive.(More)
US commercial landings of spiny dog®sh have increased ®ve-fold since 1987 to over 22 000 mt in 1993. Over 95% of the landings consist of mature females 80 cm in length. Minimum discard estimates for 1993 suggest an additional 25 000 mt of dog®sh were discarded, of which 14 000 mt were killed. LOWESS-smoothed minimum swept-area biomass estimates reveal a(More)
This introduction to the Special Feature presents the context for science during the Deepwater Horizon oil spill response, summarizes how scientific knowledge was integrated across disciplines and statutory responsibilities, identifies areas where scientific information was accurate and where it was not, and considers lessons learned and recommendations for(More)
Effective marine ecosystem-based management (EBM) requires understanding the key processes and relationships controlling the aspects of biodiversity, productivity, and resilience to perturbations. Unfortunately, the scales, complexity, and non-linear dynamics that characterize marine ecosystems often confound managing for these properties. Nevertheless,(More)
The unprecedented engagement of scientists from government, academia, and industry enabled multiple unanticipated and unique problems to be addressed during the Deepwater Horizon oil spill. During the months between the initial blowout on April 20, 2010, and the final well kill on September 19, 2010, researchers prepared options, analyses of tradeoffs,(More)
THE RESEARCH ARTICLE "IMPACTS OF BIODIVERSITY LOSS ON OCEAN ECOSYSTEM SERVICES" BY B. Worm et al. (3 Nov. 2006, p. 787) projects that 100% of seafood-producing species stocks will collapse by 2048. The projection is inaccurate and overly pessimistic. Worm et al. define "collapse" as occurring when the current year's catch is <10% of the highest observed in(More)
Parametric relationships between recruitment and an index of parental stock size assume the latter is proportionally related to spawning potential (usually indexed by spawning biomass), irrespective of the demographic composition of adults. Recent empirical information, however, suggests that spawning by older, more experienced females is more successful(More)
