Background and Aims … Coping with both UV-B radiation and desiccation was essential for early land plants. In bryophytes, UV-B screening and desiccation tolerance partially depend on the physicochemical features of cell walls, which may also constrain photosynthesis.
Metals are important nutrients to marine life but may cause toxicity at elevated concentrations. There is uncertainty about how sediment metal concentrations influence benthic biodiversity, in part because metal bioavailability depends on sediment properties.
The SCAR Krill Action Group (SKAG) provides a conduit for science to feed into the management of the Antarctic krill fishery, as well a more general forum to promote collaboration, help early career researchers, improve understanding of krill biology and ecology, and facilitate information exchange.
Polar oceans and sea ice cover 15% of the Earth's ocean surface, and the environment is changing rapidly at both poles. Improving knowledge on the interactions between the atmospheric and oceanic realms in the polar regions, a Surface Ocean–Lower Atmosphere Study (SOLAS) project key focus…
Exopolysaccharides (EPSs) are high molecular weight … carbohydrate polymers that make up a substantial … component of the extracellular polymers surrounding … most microbial cells in the marine environment.
Thorium-234 is increasingly used as a tracer of ocean particle flux, primarily as a means to estimate particulate organic carbon … export from the surface ocean. This requires determination of both the 234Th activity distribution (in order to calculate 234Th fluxes)…
