Rhodonellum psychrophilum GCM71(T), isolated from the cold and alkaline submarine ikaite columns in the Ikka Fjord in Greenland, displays optimal growth at 5 to 10°C and pH 10. Here, we report the draft genome sequence of this strain, which may provide insight into the mechanisms of adaptation to these extreme conditions.

Abstract Atlantic salmon is an economically and culturally important species. The species encounters several natural man-made threats during its migration between fresh water the ocean, which in combination may explain ongoing decline. With aim to better understand whether post-smolt behaviour influenced by physical oceanographic conditions, migratory of 173 post-smolts a high-latitude Norwegia...

Coexistence of ecotypes, genetically divergent population units, is a widespread phenomenon, potentially affecting ecosystem functioning and local food web stability. In coastal Skagerrak, Atlantic cod (Gadus morhua) occur as two such coexisting ecotypes. We applied combination acoustic telemetry, genotyping, stable isotope analysis to 72 individuals investigate movement ecology niche putative ...

*Correspondence: Erik Kristensen, Department of Biology, University of Southern Denmark, Campusvej 55, 5230 Odense, Denmark e-mail: [email protected] We aim at identifying how ecosystem functioning in shallow estuaries is affected by rapid shifts in benthic fauna communities. We use the shallow estuary, Odense Fjord, Denmark, as a case study to test our hypotheses that (1) shifts in benthic fa...

Consumption of fish and shellfish from contaminated areas may be an important source of human exposure to persistent organohalogen compounds such as polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins (PCDDs), and polychlorinated dibenzofurans (PCDFs). We determined concentrations of 2,3,7,8-substituted PCDDs and PCDFs and 19 PCB congeners in whole blood samples from three group...

Knowledge of the spatio-temporal dynamics hydromedusae and siphonophores is scarce despite their key role as predators. In temperate inlet Oslofjorden, studies dealing with these organisms are limited to a few reports from 1960s on relationship between selected species environmental conditions inner fjord, but comprehensive assessments horizontal, vertical seasonal variation pelagic hydrozoan c...

Understanding the distribution of biodiversity along environmental gradients allows us to predict how communities respond natural and anthropogenic impacts. In fjord ecosystems, overlap strong salinity temperature provides with opportunity assess spatial variation abiotic gradients. However, in Northern Chilean Patagonia (NCP), a unique at same time threatened system, macrobenthic is still poor...

Shorefast sea ice provides an important platform for winter and spring travel between coastal Arctic communities unconnected by road networks. In the past two decades, local residents have reported thinning earlier breakup of shorefast ice. Despite these assertions, however, there are few quantitative assessments how changes impacted on this study, we use high-resolution satellite remote sensin...
