Continuous moulting by Antarctic krill drives major pulses of carbon export in the north Scotia Sea, Southern Ocean

open access: yesNature Communications, 2020
Antarctic krill play an important role in biogeochemical cycles and can potentially generate high-particulate organic carbon (POC) fluxes to the deep ocean. They also have an unusual trait of moulting continuously throughout their life-cycle.

Facilitative interspecific interactions in marine vertebrates across scales: from individuals to ecosystems

open access: yesBiological Reviews, EarlyView.
ABSTRACT Facilitative interspecific interactions (FIIs) confer benefits to at least one participant without detriment to others. Although often less emphasised than antagonistic interactions in ecological studies, this review highlights the significant ecological role of FIIs across biological scales – from individual behaviours to population ...

Essential krill species habitat resolved by seasonal upwelling and ocean circulation models within the large marine ecosystem of the California Current System

open access: yesEcography, 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 ...

Vulnerability of marine megafauna to global at‐sea anthropogenic threats

open access: yesConservation Biology, EarlyView.
Abstract 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 ...

Availability to predators and a size structure of the Antarctic krill Euphausia superba in the 48.1 CCAMLR subarea

open access: yesScientific Reports
The Antarctic krill Euphausia superba is a key species in Antarctic waters, mainly because it is a major component of the diet of dominant predators, including penguins. It is also a marine living resource that is commercially harvested.

Penguin guano suppresses the grazing rate and modifies swimming behavior in Antarctic Krill (Euphausia superba)

open access: yesFrontiers in Marine Science
Antarctic krill (Euphausia superba) are a key component of the Antarctic ecosystem linking primary and some secondary production to higher trophic levels including fish, penguins, seals, and whales.

On the trophic fate of Phaeocystis pouchetii: VII. Sterols and fatty acids reveal sedimentation of Phaocystis-derived organic matter via krill fecal strings [PDF]

open access: yes, 2001
As part of a joint project on the fate of phytoplankton in Balsfjorden in Northern Norway, we investigated the trophic fate and sedimentation potential of Phaeocystis pouchetii by tracing the transition of biomarker patterns from a phytoplankton bloom to

An Oceanography‐Based Anticipatory Approach to Monitoring Fisheries and Fishery Resource Impacts From Offshore Wind Farms: A Perspective From the Mid‐Atlantic Bight, USA

open access: yesFisheries Oceanography, EarlyView.
ABSTRACT The Middle Atlantic Bight (MAB) of the eastern US differs from other offshore wind (OSW) development sites due to a unique seasonal oceanographic stratification regime. Fisheries there target migratory finfish and sedentary shellfish, the productivity and distribution of which are driven by oceanography with dynamic mesoscale features that can

Research Progress on Antarctic Krill Products and Their Quality and Safety [PDF]

open access: yesProgress in Fishery Sciences
Antarctic krill (Euphausia superba) and its products have garnered increasing attention as valuable natural resources because of their rich nutritional profile, particularly that of their bioactive compounds such as proteins and phospholipids.
