16 years of gelatinous zooplankton seasonal abundances reveal food availability and temperature as key drivers in Arctic latitudes [PDF]
Scientific ReportsYear-round long-term monitoring programs are essential for assessing ecosystem functioning and change. In the Arctic, however, continuous multi-year sampling covering all seasons remains scarce.

Unveiling pelagic-benthic coupling associated with the biological carbon pump in the Fram Strait (Arctic Ocean) [PDF]
Nature CommunicationsSettling aggregates transport organic matter from the ocean surface to the deep sea and seafloor. Though plankton communities impact carbon export, how specific organisms and their interactions affect export efficiency is unknown.

Seafloor video-acoustic monitoring in a Greenlandic glacial fjord records hyperbenthos, backward-swimming fish, and narwhals. [PDF]
PLoS ONEAutonomous video-acoustic monitoring at the sea-floor can improve our understanding of poorly documented ecosystems and help interpret active or passive acoustic data, but it has been rarely carried out, particularly in the Arctic.

Glycans in adhesion and fertilization: histochemical and ultrastructural insights from the chaetognath Spadella cephaloptera [PDF]
Frontiers in ZoologyBackground To cope with the dynamic intertidal environment, some marine invertebrates have evolved carbohydrate-based adhesive mechanisms. Glycans are also involved in reproductive processes in protostomes, yet data about their distribution and function ...

New group of the Early Palaeozoic conodont-like fossils [PDF]
Estonian Journal of Earth Sciences, 2015 The paper is devoted to the Upper Cambrian and Tremadocian organophosphatic microfossils which were hitherto treated as conodonts and assigned mainly to the genera Coelocerodontus and Viirodus.
