Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models

Environmental Toxicology, EarlyView.
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

Antarctic krill habitat suitability variation in the Southern Ocean over 20 years

Frontiers in Marine Science
Antarctic krill (Euphausia superba) is a key species that sustains the biodiversity of the Southern Ocean and is a protected and restricted fishing target in this region. Considering the significant impacts of climate change on the ecological environment

Characterization of Molecular Species and Anti-Inflammatory Activity of Purified Phospholipids from Antarctic Krill Oil

Marine Drugs, 2021
The phospholipids (PLs) from Antarctic krill oil were purified (>97.2%) using adsorption column chromatography. Forty-nine PL molecular species were characterized by ultrahigh-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry (

Common ground: Efficient, consistent, observer‐independent bioacoustic call density estimation with adjudicated ground truth and capture–recapture detection functions

Methods in Ecology and Evolution, EarlyView.
Abstract Passive acoustic recording is a cost‐effective method for monitoring vocal animals. Within this field, there is an increasing focus on automated detection algorithms for counting calls and estimating call density (in space and time). For accurate interpretation of such results, it is important to understand and correct biases introduced by ...

Determination of fluoride in Antarctic krill (Euphausia superba) using ion chromatography and its pretreatments selection

Czech Journal of Food Sciences, 2015
A rapid, sensitive and reliable method to quantify fluoride in Antarctic krill has been established. Four different pretreatment methods were used for the extraction of fluoride: double-deionised water extraction, sulphuric acid distillation ...

Two scales of distribution and biomass of Antarctic krill (Euphausia superba) in the eastern sector of the CCAMLR Division 58.4.2 (55°E to 80°E).

PLoS ONE, 2022
Regular monitoring is an important component of the successful management of pelagic animals of interest to commercial fisheries. Here we provide a biomass estimate for Antarctic krill (Euphausia superba) in the eastern sector of the Commission for the ...

Contrasting life‐history strategies of three sympatric icefish species in the northern Scotia Sea

Journal of Fish Biology, EarlyView.
Abstract Comprehending a species' life‐history strategies is crucial to inform effective conservation efforts. Commercial fishing impacts icefish (family: Channichthyidae) in the Scotia Sea, but detailed information on species‐specific life histories remains largely unknown.

Distribution and ecology of the four Macrourus species by‐caught in the longline fishery at South Georgia, Southern Ocean

Journal of Fish Biology, EarlyView.
Abstract Although Macrourus species are the main by‐catch across Southern Ocean longline fisheries, including around South Georgia, the lack of species‐specific data has hindered effective management and ecological understanding. Aggregation of macrourids at genus level masks critical interspecific differences in life‐history strategies and ...

Successful ecosystem-based management of Antarctic krill should address uncertainties in krill recruitment, behaviour and ecological adaptation

Communications Earth & Environment, 2020
Understanding of Antarctic krill must be at the heart of krill fishery management in order to protect the stock and its predators, according to a synthesis of krill ecology research.

Using a risk assessment framework to spatially and temporally spread the fishery catch limit for Antarctic krill in the west Antarctic Peninsula: A template for krill fisheries elsewhere

Frontiers in Marine Science, 2022
The west Antarctic Peninsula is an important breeding and foraging location for marine predators that consume Antarctic Krill (Euphasia superba). It is also an important focus for the commercial fishery for Antarctic krill, managed by the Commission for ...
