Assessment of microplastic-sorbed contaminant bioavailability through analysis of biomarker gene expression in larval zebrafish
Read more of: Assessment of microplastic-sorbed contaminant bioavailability through analysis of biomarker gene expression in larval zebrafishMicroplastics (MPs) are prevalent in marine ecosystems. Because toxicants (termed here “co-contaminants”) can sorb to MPs, there is potential for MPs to alter co-contaminant bioavailability. Our objective was to demonstrate […]

Genetic diversity and biogeography of the south polar water bear Acutuncus antarcticus (Eutardigrada : Hypsibiidae) – evidence that it is a truly pan-Antarctic species
Read more of: Genetic diversity and biogeography of the south polar water bear Acutuncus antarcticus (Eutardigrada : Hypsibiidae) – evidence that it is a truly pan-Antarctic speciesAntarctica is an ice-dominated continent and all its terrestrial and freshwater habitats are fragmented, which leads to genetic divergence and, eventually, speciation. Acutuncus antarcticus is the most common Antarctic tardigrade […]

Seabird diversity hotspot linked to ocean productivity in the Canary Current Large Marine Ecosystem
Read more of: Seabird diversity hotspot linked to ocean productivity in the Canary Current Large Marine EcosystemUpwelling regions are highly productive habitats targeted by wide-ranging marine predators and industrial fisheries. In this study, we track the migratory movements of eight seabird species from across the Atlantic; […]

Migration strategies of common eiders from Svalbard: implications for bilateral conservation management
Read more of: Migration strategies of common eiders from Svalbard: implications for bilateral conservation managementThe Arctic is a highly seasonal environment with a harsh climate and extensive sea ice cover during the winter. Consequently, most Arctic-breeding seabirds migrate south to reach more benign environmental […]

Recent trends in numbers of wandering (Diomedea exulans), black-browed (Thalassarche melanophris) and grey-headed (T. chrysostoma) albatrosses breeding at South Georgia
Read more of: Recent trends in numbers of wandering (Diomedea exulans), black-browed (Thalassarche melanophris) and grey-headed (T. chrysostoma) albatrosses breeding at South GeorgiaSouth Georgia supports globally important populations of seabirds, including the wandering albatross Diomedea exulans, black-browed albatross Thalassarche melanophris and grey-headed albatross T. chrysostoma, currently classified by the world Conservation Union […]

Molecular snapshot of an intracellular freezing event in an Antarctic nematode
Read more of: Molecular snapshot of an intracellular freezing event in an Antarctic nematodeThe Antarctic nematode, Panagrolaimus sp. DAW1 (formerly called Panagrolaimus davidi), is the best documented example of an organism able to survive intracellular ice formation in all of its compartments. Not […]

Distribution of pelagic larvae of benthic marine invertebrates in the Bellingshausen Sea
Read more of: Distribution of pelagic larvae of benthic marine invertebrates in the Bellingshausen SeaDuring November and December 1992, plankton samples were collected using a ring net of mesh size 200 μm vertically hauled through a 600 m water column, at five stations along […]

A cyphonautes larva (Bryozoa: Gymnolaemata) from the Bellingshausen Sea, Antarctica
Read more of: A cyphonautes larva (Bryozoa: Gymnolaemata) from the Bellingshausen Sea, AntarcticaBryozoans are an important component of the sessile, suspension-feeding fauna on the Antarctic continental shelf, (Knox & Cameron, 1970; Dell, 1972; Winston, 1983; Winston & Heimberg, 1988). Antarctic bryozoan faunas […]
