Comparing voluntary and government-mandated management measures for meeting sustainable fishing targets.

Management of natural resources and environmental systems has often involved top-down approaches in which government agencies set and enforce regulations on extractive activities. More recently, market-driven approaches were introduced to incentivise producers to voluntarily engage in practices that align with management objectives and support regulations. For the first time, we compare government and voluntary approaches within fisheries management systems and quantify their relative influences on the sustainability status of fish populations.

Is the long-tailed macaque at risk of extinction?

We review the evidence that long-tailed macaques are at risk of extinction and find that papers supporting this argument present no data supporting a hypothesized decline in abundance. These papers contain numerous misrepresentations of the published literature. Long-tailed macaques thrive in human-altered habitats, are listed by the International Union for the Conservation of Nature as an invasive species of concern, and have shown the ability to increase by 7%-10% per year from low numbers, making the probability of extinction very low.

Fished or farmed: Life cycle impacts of salmon consumer decisions and opportunities for reducing impacts.

Salmon is a nutritious and popular food among consumers predominantly in wealthy countries around the world. Since the mid-1990s farmed salmon production has exceeded wild salmon harvest, and is now 80 % of total global salmon supply. The environmental impacts of farmed salmon are frequently discussed and consumers are faced with a multitude of choices even after deciding to have salmon for dinner: species, production method, origin, product form.

Trade-offs between bycatch and target catches in static versus dynamic fishery closures.

While there have been recent improvements in reducing bycatch in many fisheries, bycatch remains a threat for numerous species around the globe. Static spatial and temporal closures are used in many places as a tool to reduce bycatch. However, their effectiveness in achieving this goal is uncertain, particularly for highly mobile species.
