Microbial mats are found globally in dynamic aquatic environments. Visually different morphotypes (orange-red and black-green) also show different rates of nitrogen fixation and biogeochemical activity. Glacial meltwater communities in the McMurdo Dry . . .

Chemical contaminants in estuaries may interfere with an organism’s ability to ward against parasites and disease which can shape patterns of genetic diversity in populations, including at the Major Histocompatibility Complex (MHC) which helps recogni . . .

Phytoplankton form the base of the global marine carbon cycle. Measurements of primary production are integral to understanding fluxes between the atmosphere and both organic and inorganic carbon pools in the ocean. Virtually all measurements today ar . . .

Increases in water temperature and salinity that are predicted to occur with climate change are hypothesized to alter phytoplankton communities, expand cyanobacteria blooms, and alter food web structure in estuaries. For example, since 1999 blooms of . . .

Echinoids comprise a diverse group of Echinoderms composed of around 1000 extant species. The sea urchin family, Trigonocidaridae exemplifies echinoid diversity, being found in almost every marine ecoregion from the intertidal zone to depths over 3,00 . . .

This study demonstrated that Delta Microcystis can utilize different forms o f inorganic and organic N, with the greatest capacity for NH4+ uptake and the least for glutamic acid uptake, though N uptake did not always follow the classic Michaelis-Ment . . .

The 2009 Integrated Ocean Drilling Program Expedition 323 (Exp 323) to the Bering Sea recovered the first continuous sediment cores of the Pleistocene glacial cycles from sites throughout the marginal sea. Sediments in this region are dominated by dia . . .

Increasing use of ecosystem-based management strategies, which are often applied to broad geographic areas and preclude extractive activities, are creating a need for rapid, cost-effective monitoring of large areas. Visual surveys are increasingly bei . . .

Multiple paternity is widespread across many taxa including birds, insects and marine species. Despite multiple paternity being rare among studied crustaceans, a study found that -93% of female porcelain crabs, Petrolisthes cinctipes, mate with more t . . .
