When marine turtles and vessels overlap: Mapping encounter risk along Florida's Atlantic coast

Conservation Science and Practice, EarlyView.
Marine turtles face significant risks from vessel encounters, interventive measures require knowledge of the overlap between turtles and vessels. To identify areas and seasons with the highest likelihood of turtle–vessel interactions and inform regional management, we assessed the spatiotemporal overlap between turtles, vessels and stranded turtles ...

The contribution of action research to actionable knowledge in the field of management

European Management Review, EarlyView.
Abstract A key strength of action research is producing actionable knowledge that is relevant for addressing complex issues, including the grand challenges of our time, but this production is hindered by the underdevelopment of specific quality criteria for assessing such knowledge.

Residency and Space Use of Endangered Smoothhound Sharks (Mustelus mustelus) in Relation to Marine Protection and Demersal Longline Fishing Along South Africa's South Coast

Fisheries Management and Ecology, EarlyView.
ABSTRACT Shark populations are declining globally and the effectiveness of marine protected areas (MPAs) as a conservation tool may vary by species and environmental context. This study assessed space use and residency of smoothhound sharks (Mustelus mustelus)—an endangered, yet highly exploited shark—in relation to spatial protection and fishing risk ...

Revealing potential Atlantic salmon bycatch hotspots from pelagic fisheries landings across the Northeast Atlantic

Journal of Fish Biology, EarlyView.
Abstract Atlantic salmon (Salmo salar) marine survival has declined markedly over the past five decades, leading to concerns about future population viability. While many studies have explored the impacts of stressors such as climate change and predation, less is known about bycatch from pelagic fisheries targeting finfish species.

Research on Trajectory Reconstruction Method Using Automatic Identification System Data for Unmanned Surface Vessel

IEEE Access, 2019
The unmanned surface vessel (USV) trajectory with spatial and temporal information plays an important role in its positioning and navigation. Unlike traditional trajectory reconstruction methods, this paper proposes a novel method based on the automatic ...
