Small pelagic fish (SPF) are critical to the trophodynamic structure and function of marine systems and support some of the most valuable and socially important fisheries worldwide. Their “boom and bust” population dynamics, shifts in distribution, and importance as forage resources for other fish stocks place unique challenges to assessing and managing SPF. In response to these challenges, an international working group was f...
SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
Environmental drivers of early life-stage survival are critical to understanding recruitment variability and improving ecosystem-based fisheries management. We investigate how regional ocean circulation influences blue whiting ( Micromesistius poutassou ) recruitment in the Northeast Atlantic by combining multi-decadal transport analyses with Lagrangian particle simulations. Using ocean reanalysis, we compute 28-year (1993-202...
Greenhouse gas (GHG) emissions from coastal aquaculture are an emerging environmental concern, with implications for ecosystem sustainability and climate mitigation. In this preliminary field-based study, we quantified carbon dioxide (CO 2 ), methane (CH 4 ), and nitrous dioxide (N 2 O) fluxes from 35 randomly selected prawn farms in coastal Bangladesh, at a single time point using the floating chamber method, with concurrent...
Regional ecosystem responses to environmental drivers in cold‐water lakes evaluated using stable isotopes of salmonid fishesNARA Subscribed
Diverse environmental drivers influence food web energy and nutrient flows, a key ecosystem function, yet their relative importance remains poorly known. We compiled thousands of bulk stable isotope measurements (carbon and nitrogen) of brown trout ( Salmo trutta , n = 2854) and Arctic charr ( Salvelinus alpinus , n = 3062) from 120 cold‐water lakes across northern Europe, spanning 0.02 to 1090 km 2 in size, to quantify the re...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
