New research from Gerardo Martín and colleagues looks at how we might support shark species if protected areas are multi-use and still open to fishing. The key is focusing on reefs preferred by sharks and developing our knowledge of shark movement pathways. Here the authors share their work and look at how we can improve species conservation while still supporting communities that depend on coral … Continue reading Protected high-value reefs and movement pathways improve conservation of reef sharks
Using the example of a spatial recreational fishery for lake trout in northern Canada, Wilson et al. present an exciting analysis of how human behaviour and local ecological dynamics interact to shape landscape-level outcomes. Associate Editor, Robert Arlinghaus highlights why this article has been selected as an Editor’s Choice. The field of applied ecology is increasingly moving towards studies that integrate human behaviour and ecological … Continue reading Editor’s Choice 57:02 – Understanding anglers as spatially mobile human predators in freshwater landscapes
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?
Fisheries management approaches need to consider angler behaviour, or there could be knock-on effects once practices are implemented. Synchrony – an emergent property of recreational fisheries by Kaemingk et al. is published today in Journal of Applied Ecology. Understanding how people use natural resources in space and time is challenging, but necessary for proper management. Biologists often face difficult and urgent management decisions; these decisions may … Continue reading Should we care if angler participation patterns are different?
Morten Frederiksen discusses conflicts between wintering cormorants and fisheries, following the recent article, Where do wintering cormorants come from? Long-term changes in the geographical origin of a migratory bird on a continental scale. Cormorants are very efficient predators of fish in shallow waters. They are particularly good at exploiting artificially high densities of fish. Predictably, this has led to widespread conflicts with human fisheries interests. Although fishermen … Continue reading Where do wintering cormorants in Europe come from – and does it matter?
Assessing the effectiveness of marine reserves and evaluating species recovery after closure to towed mobile fishing gear; Associate Editor, Steph Januchowski-Hartley comments on the article, Recovery linked to life history of sessile epifauna following exclusion of towed mobile fishing gear by Kaiser et. al. Reserves, or protected areas, are frequently used to mitigate impacts from human uses. In marine waters these reserves are often established to afford … Continue reading Evaluating the temporal effectiveness of marine reserves
In this post Jeremy Vaudo and Mahmood Shivji discuss their article ‘Long-term satellite tracking reveals region-specific movements of a large pelagic predator, the shortfin mako shark, in the western North Atlantic Ocean’ In your paper you used satellite telemetry to investigate movements and seasonal distributions of shortfin mako sharks (Isurus oxyrinchus) in the western North Atlantic Ocean. What were the biggest challenges for this work? … Continue reading Tracking an apex marine predator – the shortfin mako shark
In this post Associate Editor Verena Trenkel discusses a paper she recently handled from Michael Melnychuk and colleagues ‘Informing conservation strategies for the endangered Atlantic sturgeon using acoustic telemetry and multi-state mark–recapture models‘ According to the International Union for Conservation of Nature (ICUN), ten out 17 sturgeon species are currently critically endangered. Among the two species listed as least concern is Atlantic sturgeon which occurs … Continue reading New techniques for Atlantic sturgeon conservation
In this post Rebecca Weeks discusses her recent paper ‘Using reef fish movement to inform marine reserve design‘. The majority of marine protected areas in Pohnpei (Federated States of Micronesia) are too small to protect the species that people care about most. But when livelihoods depend on fishing, establishing large no-take areas is a big challenge. Overfishing and unsustainable fishing practices are amongst the greatest threats … Continue reading Using reef fish movement to inform marine reserve design
