There is mounting evidence that climate change is affecting commercial fish species. In their latest research, Ikpewe and colleagues investigate the effect of temperature on fish sizes in two neighbouring regions, displaying contrasting trends in warming. The warming of our oceans due to climate change is affecting marine life in numerous ways. Fish populations, in particular, are experiencing changes in productivity, distribution, growth and the … Continue reading Smaller adults and bigger juveniles: how global warming is affecting our fish populations.
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
Infectious diseases have recently been acknowledged as an important threat for wild populations, notably seabirds. In order to implement efficient surveillance and management programmes, it is critical to look beyond the sick individuals to identify the individuals or species involved in cryptic epidemiological processes, such as pathogen spread. Amandine Gamble et al. summarise their recent research on the potential role of predators and scavengers in … Continue reading Predator and scavenger movements as opportunities for pathogen spread among endangered seabirds
Part of our Spotlight, Management of wide-ranging species, Thomas A. Clay explains how advances in remote tracking technology are offering us a glimpse into the mysterious life of the albatross in the hope of developing conservation measures to protect seabirds from bycatch risks. The authors have adapted this post from an article they previously shared with BirdLife International. Albatrosses are iconic voyagers, well known for … Continue reading Identifying fishery risk zones for seabird populations
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?
This month, Journal of Applied Ecology turns its focus to the health of the worlds’ oceans, with a new Spotlight, Conservation in marine habitats. Ignasi Montero-Serra summarizes the importance of this collection of work that provides a variety of cutting-edge tools to quantify the impact of major stressors, and to guide management actions across marine habitats; from the intertidal to the deep sea. Marine habitats … Continue reading Spotlight: Conservation in marine habitats
Long-lived species take longer to recover from the effects of bottom trawling by commercial fisheries according to recent research from Hiddink et al. Watch this video from PROJECT BENTHIS to discover more about the importance of longevity and benthic animal traits. Introduction by Associate Editor, Verena Trenkel. Bottom trawling by commercial fisheries affects not only the target species — typically fish and shellfish — but … Continue reading Benthos longevity matters …
When it comes to developing management tools, how do we keep up with constantly changing ecosystems? Associate Editor, Annabel Smith explains the important step forward made by Welch et al’s research into dynamic management tools. Scientists have been very good at developing guidelines for management of natural systems. Streams of conceptual frameworks are published every year, to the point that we now have frameworks for … Continue reading Dynamic technology for dynamic ecosystems
New research published today (9th May 2018) uses electronic tags to highlight the risk of shark mortality through unintentional capture in fishing gear. Associate Editor, Andre Punt, comments on the new paper by Benson et al., Juvenile survival, competing risks, and spatial variation in mortality risk of a marine apex predator. One of the most influential parameters in any population dynamics model is the rate of … Continue reading Juvenile natural mortality is a hard parameter to estimate, but it can be done with pop-up archival tags
From fisheries management, to reintroductions and land use policies, here are some highlights from issue 55:3: Addressing global fisheries management challenges in a changing world Our latest Spotlight, showcasing high-quality and topical research Targeted supplementary feeding supports reintroduction of endangered raptors This issue’s Editor’s Choice Is environmental legislation conserving tropical stream faunas? Looking beyond the trees in tropical forest landscapes Evaluating the temporal effectiveness of marine reserves Species recovery … Continue reading Issue 55:3
