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.

Integrated Approaches to Long-Term Studies of Urban Ecological Systems Integrated Approaches to Long-Term Studies of Urban Ecological Systems

TL;DR: An emerging approach to understanding the ecology of urban areas by contrasting these two metropolises is described, and a call to action for ecologists to integrate their science with that of social scientists to achieve a more realistic and useful understanding of the natural world in general and its ecology in particular is presented.

Protected areas in fisheries: a two‐patch, two‐species model*

TL;DR: In this paper, a stochastic bioeconomic model of a hypothetical predator-prey fishery is used to test the performance of protected areas in a fishery with heterogenous environments.

Investigating the consequences of Marine Protected Areas for the South African deep-water hake (Merluccius paradoxus) resource

TL;DR: Edwards et al. as mentioned in this paper presented a simulation model that explores spatial closure options, and applied it to the demersal hake trawl fishery off South Africa, showing that area closures would have a negligible benefit for the fishery, regardless of the level of hake movement between areas.

Balancing complexity and feasibility in Mediterranean coastal food-web models: uncertainty and constraints

TL;DR: An approach for identifying the optimum model structure that considers trade-offs between feasibility, complexity, and uncertainty, using a Mediterranean coastal ecosystem as a case study and a simplified model comprising 32 functional groups was identified as the best compromise between model complexity and reliability.

Biodiversity and stability in grasslands

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

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.
