Marine n‐3 Polyunsaturated Fatty Acids Mitigate Obesity Traits Through PRDM16‐Driven Gene–Nutrient Interaction and Spatiotemporal Scale Browning Process

open access: yesFood Frontiers, EarlyView.
This large cohort study of 45,664 participants from the UK Biobank provides strong epidemiological evidence that fish oil use was associated with 12% and 7% lower risks of obesity and high body fat percentage, respectively. Mechanistically, marine n‐3 polyunsaturated fatty acids mitigate obesity traits through PRDM16‐driven gene–nutrient interactions ...

A new Activity Monitor for Aquatic Zooplankter (AMAZE) allows the recording of swimming activity in wild-caught Antarctic krill (Euphausia superba)

open access: yesScientific Reports
Antarctic krill (Euphausia superba, hereafter krill) is a pelagic living crustacean and a key species in the Southern Ocean ecosystem. Krill builds up a huge biomass and its synchronized behavioral patterns, such as diel vertical migration (DVM ...

Parasite infection shapes the pathobiome and behavior of marine zooplankton

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract When assessing the total impact of disease in a host, it is important to consider not only the disease‐carrying agent but also all symbionts, as they affect and are affected by the course of disease. This concept of a pathobiome is increasingly recognized in disease ecology, but is not well‐investigated in natural systems.

A method to estimate prey density from single-camera images: A case study with chinstrap penguins and Antarctic krill.

open access: yesPLoS ONE
Estimating the densities of marine prey observed in animal-borne video loggers when encountered by foraging predators represents an important challenge for understanding predator-prey interactions in the marine environment. We used video images collected

Arctic‐breeding black‐legged kittiwakes show individual variation in foraging responses to glacial conditions without consequences for reproductive output

open access: yesOikos, EarlyView.
Behavioural plasticity is likely to influence how individuals continue to access resources under rapid climate change. Plasticity will be particularly important at highly dynamic, prey‐rich foraging areas such as upwelling fronts of marine‐terminating glaciers in the high Arctic, where profitability varies significantly across space and time ...

Protozoans as a food source for Antarctic krill, Euphausia superba: complementary insights from stomach content, fatty acids, and stable isotopes [PDF]

open access: yes, 2006
We studied the diet of Antarctic krill, Euphausia superba, at five stations across the southwest Atlantic sector in summer 2003 by analyzing stomach content, fatty acids, and stable isotopes on the same individuals.

Ground‐truthing of satellite imagery to assess seabird colony size: A test using Adélie penguins

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Adélie penguin colony size can be estimated from space using very high‐resolution (VHR; 0.3–0.6 m resolution) satellite imagery due to the contrast between their guano stain and the surrounding terrain. Our study assessed the utility of VHR imagery for making indirect assessments of changes in colony size.

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

open access: yesJournal 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.

Reviewing seas of data: Integrating image‐based bio‐logging and artificial intelligence to enhance marine conservation

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Conservation of marine ecosystems can be improved through a better understanding of ecosystem functioning, particularly the cryptic underwater behaviours and interactions of marine predators. Image‐based bio‐logging devices (including images, videos and active acoustic) are increasingly used to monitor wildlife movements, foraging behaviours ...
