Unicellular cyanobacteria fix N2 in the subtropical North Pacific Ocean
Fixed nitrogen (N) often limits the growth of organisms in terrestrial and aquatic biomes, and N availability has been important in controlling the CO2 balance of modern and ancient oceans. TheExpand

High rates of N2 fixation by unicellular diazotrophs in the oligotrophic Pacific Ocean
The availability of nitrogen is important in regulating biological productivity in marine environments. Deepwater nitrate has long been considered the major source of new nitrogen supporting primaryExpand

Experiments linking nitrogenase gene expression to nitrogen fixation in the North Pacific subtropical gyre
We examined diazotroph activity in controlled experiments containing natural populations of nitrogen (N2)-fixing microbes collected offshore from Kane'ohe Bay, Hawai'i, and from Station ALOHA (AExpand

Assessment of Recent Habitat Conditions of Eastern Oyster Crassostrea virginica Bars in Mesohaline Chesapeake Bay
Abstract Eastern oysters Crassostrea virginica in Chesapeake Bay, USA, have been subjected to intense harvest pressure since about 1850 and to disease epizootics since the 1950s. Combined, theseExpand

Bigger is better: size-selective mortality throughout the life history of a fast-growing clupeid, Spratelloides gracilis
A cohort of the fast-growing sprat Spratelloides gracilis was sampled during late-larval, juvenile and adult life-history phases using light traps on the North West Shelf of Western Australia.Expand

Specific amplification of the 18S rRNA gene as a method to detect zebra mussel (Dreissena polymorpha) larvae in plankton samples
An important issue in the management of zebra mussel (Dreissena polymorpha) populations is early, rapid, and accurate detection of the planktonic larvae (veliger) of the zebra mussel. The goal ofExpand

Development and Utilization of Genetic Probes for Studying Zebra Mussel Veligers
A key issue in the management of zebra mussel populations is early, rapid, and accurate detection of the planktonic forms of the mussel veligers. In this study, an alternative technology toExpand

Long-term observations of foraminifera in situ
ROMEO — the world’s southernmost cabled underwater observatory, located in Explorers Cove, Antarctica, was used to image Cibicides refulgens living epizoically on the scallop Adamussium colbeckiExpand
