TLDR
In this article, a more holistic approach incorporating interspecific interactions and physical environmental influences would contribute to greater sustainability by reducing the uncertainty in predictions and transforming the management process to reduce the influence of pressure for greater harvest holds more immediate promise.Abstract:
The global marine fish catch is approaching its upper limit. The number of overfished populations, as well as the indirect effects of fisheries on marine ecosystems, indicate that management has failed to achieve a principal goal, sustainability. This failure is primarily due to continually increasing harvest rates in response to incessant sociopolitical pressure for greater harvests and the intrinsic uncertainty in predicting the harvest that will cause population collapse. A more holistic approach incorporating interspecific interactions and physical environmental influences would contribute to greater sustainability by reducing the uncertainty in predictions. However, transforming the management process to reduce the influence of pressure for greater harvest holds more immediate promise.read more

Making Space for Community Resource Management in Fisheries
TL;DR: The dominant discourse of fisheries science and management, bioeconomics, places the behavior of individual fishermen operating on an open-access commons at the center of its understanding of fisheries resources and the fishing industry.

The missing layer: Geo-technologies, communities, and implications for marine spatial planning
TL;DR: In this paper, a participatory method was used to map the presence of fishing communities at sea, and the lessons learned concerning the spatial representation of communities informed not only fisheries, but other sectors struggling to incorporate similarly the human dimensions of the marine environment in assessment and planning.

Predator diversity hotspots in the blue ocean
TL;DR: It is concluded that the seemingly monotonous landscape of the open ocean shows rich structure in species diversity and that these features should be used to focus future conservation efforts.

Human-modified ecosystems and future evolution
TL;DR: It is concluded that future evolution will be shaped by the authors' awareness of the global threats, their willingness to take action, and their ability to do so, which is presently hampered by several factors.

Why are quantitative relationships between environmental quality and fish populations so elusive
TL;DR: Quantifying EQ effects on fish popu- lations can be improved by considering these issues in analyses, and by taking a true multidisciplinary approach that combines individual-based modeling and life history theory.

Biodiversity and stability in grasslands
David Tilman,John A. Downing +1 more
TL;DR: This article showed that primary productivity in more diverse plant communities is more resistant to, and recovers more fully from, a major drought and that each additional species lost from our grasslands had a progressively greater impact on drought resistance.

Primary production required to sustain global fisheries
Daniel Pauly,Villy Christensen +1 more
TL;DR: In this paper, the mean of reported annual world fisheries catches for 1988-1991 (94.3 million t) was split into 39 species groups, to which fractional trophic levels, ranging from 1.0 (edible algae) to 4.2 (tunas), were assigned, based on 48 published Trophic models, providing a global coverage of six major aquatic ecosystem types.
