Drones Confirm Costa Rican Waters Sea Turtles
2018/2/1
Hundreds of thousands of sea turtles come ashore to lay their eggs during mass-nesting events at Ostional National Wildlife Refuge on Costa Rica’s Pacific coast, making it one of the most important ne...
Advective transport of diazotrophs and importance of their nitrogen fixation on new and primary production in the western Pacific warm pool
Advective transport diazotrophs importance their nitrogen fixation new primary production in the western Pacific warm pool
2014/4/2
The western Pacific warm pool (WPWP) is a region of low nutrient and chlorophyll concentrations in which new production is generally considered to be supported by upward fluxes of nitrate from the dee...
The relative importance of heterotrophic bacteria to pelagic ecosystem dynamics varies with reservoir trophic state
heterotrophic bacteria pelagic ecosystem dynamics varies reservoir trophic state
2014/4/17
We tested the hypothesis that nutrient sequestration and carbon flow through heterotrophic bacteria is relatively highest in oligotrophic systems and decreases with trophic state in 17 reservoirs in T...

Relative importance trophic interactions nutrient enrichment in seagrass ecosystems A broad-scale field experiment the Baltic–Skagerrak area
2014/4/17
The interaction of eutrophication and predation in structuring seagrassZostera marinaL. ecosystems was assessed in a field experiment in three regions along an estuarine salinity gradient, from southe...
Nutritional importance of benthic bacteria for deep-sea nematodes from the Arctic ice margin: Results of an isotope tracer experiment
Nutritional importance benthic bacteria deep-sea nematodes the Arctic ice margin Results an isotope
2014/4/16
A stable isotope (13C)-labeling experiment was performed to quantify the importance of bacterial carbon as a food source for an Arctic deep-sea nematode community. Bacterial functional groups were iso...
Biological consumption of dimethylsulfide (DMS) and its importance in DMS dynamics in the Ross Sea, Antarctica
Biological consumption of dimethylsulfide DMS importance in DMS dynamics in the Ross Sea Antarctica
2014/4/18
We studied the biological consumption of dimethylsulfide (DMS) and its role in controlling DMS concentrations in the Ross Sea, Antarctica, during the spring (Nov) and summer (Jan) of 2005. Surface DMS...
The relative importance of microbial and classical food webs in a highly productive coastal upwelling area
microbial classical food webs highly productive coastal upwelling area
2014/4/22
We present an analysis of seasonal variations in the trophic pathways of carbon in a highly productive coastal upwelling region in the Humboldt current system off Chile. Seasonal changes in phytoplank...
Importance of scale to the relationship between abundance of sardine larvae, stability, and food
abundance sardine larvae, stability food
2014/4/22
We used a spatially explicit regression model to relate sardine (Sardinops sagax) larval abundance to water column stability, phytoplankton, and zooplankton off South Australia. The distribution of sa...
Lipids from stomach oil of procellariiform seabirds document the importance of myctophid fish in the Southern Ocean
Lipids from stomach oil procellariiform seabirds document myctophid fish Southern Ocean
2014/4/21
We investigated the relative importance of myctophid fish and Antarctic krill in the diet of adult flying seabirds of the Southern Ocean. The main prey of short-tailed shearwaters Puffinus tenuirostri...
Relative importance of CO2 recycling and CH4 pathways in lake food webs along a dissolved organic carbon gradient
CO2 recycling CH4 pathways lake food webs a dissolved organic carbon gradient
2014/5/4
Terrestrial ecosystems export large quantities of dissolved organic carbon (DOC) to aquatic ecosystems. This DOC can serve as a resource for heterotrophic bacteria and influence whether lakes function...
Uptake of dissolved organic matter (DOM) and its importance to metabolic requirements of the zebra mussel, Dreissena polymorpha
dissolved organic matter metabolic requirements zebra mussel Dreissena polymorpha
2014/5/8
We determined the rates at which Dreissena polymorpha assimilated radiolabeled acetate, monosaccharides, amino acids, and fatty acids at environmental concentration levels. The mussels incorporated al...
