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

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).

Frontiers in Marine Science, 2022 The overwinter survival mechanisms of Antarctic krill, Euphausia superba, are poorly characterized, especially for juveniles. It has been suggested that juveniles adopt a mix of strategies characteristic of both larvae and adults.

Current status and trends of Antarctic krill in the east Antarctica [PDF]
, 2016 Mahy studies on the ecology of Antarctic krill (Euphausia superba) have been carried out since the Discovery expeditions (Marr, 1962); however, most of the survey efforts have been concentrated in the Southwest Atlantic sector (e.g., Watkins et al., 2003)

Ecography, 2020 foundational forage species and their negative response to large-scale climate variations, such as El Niño and marine heatwave conditions. The approach can be easily transferred to other eco-systems or krill species that respond to similar ocean and ...

Record phenological responses to climate change in three sympatric penguin species
Journal of Animal Ecology, EarlyView.This paper is impressive because we managed to monitor extensively a really difficult place to reach and operate in. We deployed 77 cameras across Antarctica and the Sub Antarctic islands to monitor three different species of penguins. We found that they are the fastest advancing vertebrates with respect to their timing of breeding.

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.

Methods 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 ...
