Robustness and management performance of MSY reference points derived from the hockey-stick stock-recruitment model under structural uncertainty

This study evaluates the robustness of MSY reference points derived from the hockey-stick stock-recruitment model under structural uncertainty and shows that combining them with precautionary measures can achieve comparable management outcomes to true models.

Comparative food-web analysis of bluefin tuna spawning habitats in the eastern Indian Ocean and Gulf of Mexico

The paper compares food-web structures in tuna spawning habitats of the Gulf of Mexico and Argo Basin, finding higher ecosystem efficiency in the Argo Basin due to differences in zooplankton herbivory and nutrient cycling.

Potential and limits of the evolutionary rescue of harvested food webs

This study examines how evolution affects the robustness of marine food webs under fishing pressure, finding that evolution often enhances robustness but can also lead to negative outcomes under certain conditions.

No-take zone effectiveness in linear coastal systems depends on spatially heterogeneous placement and larval dispersal directionality

This study shows that no-take zones in linear coastal systems improve population recovery when aligned with larval dispersal direction, but their effectiveness depends on spatial placement and dispersal patterns.

Thermal niche warming is more consistent than range shifts in marine species under climate change

The paper shows that marine species' thermal niches have warmed more than their spatial redistribution under climate change.
