Energy densities of key prey species in the California Current Ecosystem

Frontiers in Marine Science
The energetic content of primary and secondary consumers is central to understanding ecosystem functioning, community assembly, and trophodynamics. However, these foundational data are often limited, especially for marine ecosystems.

Circulating Omega‐3 Fatty Acids and Cardiometabolic Outcomes: A Systematic Review of Publications From UK Biobank

Lipids, EarlyView.
ABSTRACT Studies have shown that omega‐3 fatty acids may protect against cardiovascular diseases (CVDs) and related metabolic conditions. UK Biobank is a large cohort study that includes data on plasma omega‐3 fatty acids at study entry and health outcomes during the follow‐up period.

Emerging Pollutants in Chinstrap Penguins and Krill from Deception Island (South Shetland Islands, Antarctica)

Toxics
This study aimed to evaluate the presence of emerging pollutants [perfluorinated compounds, phthalates and bisphenol A (BPA)] in chinstrap penguins (Pygoscelis antarctica) and krill (Euphausia superba) from Deception Island (South Shetland Islands ...

Mobulid rays feed on euphausiids in the Bohol Sea [PDF]

Royal Society Open Science, 2017
Mobulid rays have a conservative life history and are caught in direct fisheries and as by-catch. Their subsequent vulnerability to overexploitation has recently been recognized, but fisheries management can be ineffective if it ignores habitat and prey ...

Satellite-Based Lagrangian Model Reveals How Upwelling and Oceanic Circulation Shape Krill Hotspots in the California Current System

Frontiers in Marine Science, 2022
In the California Current System, wind-driven nutrient supply and primary production, computed from satellite data, provide a synoptic view of how phytoplankton production is coupled to upwelling. In contrast, linking upwelling to zooplankton populations

Semi‐automated seal detection on the Western Antarctic Peninsula: an unsupervised machine learning approach for detecting ice seals in aerial survey data

Remote Sensing in Ecology and Conservation, EarlyView.
This study presents a semi‐automated, rule‐based image analysis pipeline to detect ice seals in aerial surveys of the Western Antarctic Peninsula during an unusually low sea ice year. By using simple hierarchical clustering instead of deep learning, the method substantially reduced human annotation effort while achieving 82% recall, identifying 758 ...

Safety assessment of Superba™ krill powder: Subchronic toxicity study in rats

Toxicology Reports, 2015
The safety of krill powder was assessed in a subchronic 13-week toxicity study where rats were fed krill powder or control diets. The krill powder inclusion in the test diet was 9.67% (w/w).

Environmental variability and krill abundance in the central California current: Implications for ecosystem monitoring

Frontiers in Marine Science, 2023
Krill are a direct conduit between primary productivity and recreationally and commercially important higher trophic level species globally. Determining how krill abundance varies with temporal environmental variation is key to understanding their ...

Rhyming in the cold: first evidence of soniferous fishes in the Southern Ocean

Remote Sensing in Ecology and Conservation, EarlyView.
The acoustic ecology of Southern Ocean fishes remains unknown due to a lack of dedicated acoustic research on the fishes of this ocean. Passive acoustic monitoring data were collected at the South African sub‐Antarctic Prince Edward Islands using an underwater acoustic recorder, and towed underwater Ski‐Monkey cameras were deployed to identify fish ...

Effects of krill oil and lean and fatty fish on cardiovascular risk markers: a randomised controlled trial

Journal of Nutritional Science, 2018
Fish consumption and supplementation with n-3 fatty acids reduce CVD risk. Krill oil is an alternative source of marine n-3 fatty acids and few studies have investigated its health effects.
