Editor’s Choice 56:8 – could periodic fisheries closures become a more mainstream tool in the future?

Associate Editor, Hedley Grantham discusses our August Editor’s Choice article, Optimized fishing through periodically harvested closures by Carvalho et al. Fisheries management, and sustainable marine management more broadly, require an assembly of management strategies to be effective. Two primary fisheries management tools are catch and effort restrictions, which are often not very spatially-specific. In contrast, spatially-explicit permanent fishing closures like no-take marine reserves are an … Continue reading Editor’s Choice 56:8 – could periodic fisheries closures become a more mainstream tool in the future?

Does harvest dampen or amplify the effects of climate change on natural populations?

Gamelon et al. aim to answer this question in their recently published Commentary. The harvest-interaction hypothesis Natural populations in marine to terrestrial ecosystems are experiencing a climate that is rapidly changing. These changes can induce marked fluctuations in population size over years and lead to higher extinction risk. In addition to human-induced changes in climate, many natural populations are affected by harvest, with removal of … Continue reading Does harvest dampen or amplify the effects of climate change on natural populations?

Anyone’s game: do gamebird releases lead to increases in generalist predators?

In their new research, published this week, Henrietta Pringle and colleagues recommend the recording of gamebird releases and predator numbers. Every year, 40-50 million non-native gamebirds (ring-necked pheasant Phasianus colchius and red-legged partridge Alectoris rufa) are released in the UK, equivalent to around 46000 tonnes of biomass. Fewer than half these birds are shot, with the remaining birds predated, scavenged or surviving to breed or … Continue reading Anyone’s game: do gamebird releases lead to increases in generalist predators?
