Analysis of Energy Flow in US GLOBEC Ecosystems Using End-to-End Models
Sea continental shelf the ecosystem nutrition structure global ocean ecosystem dynamics
2015/7/16
End-to-end models were constructed to examine and compare the trophic structure and energy flow in coastal shelf ecosystems of four US Global Ocean Ecosystem Dynamics (GLOBEC) study regions: the North...
Climate Impacts on Zooplankton Population Dynamics in Coastal Marine Ecosystems
Global ocean ecosystem dynamics zooplankton predators Marine ecosystems reproduction
2015/7/16
The 20-year US GLOBEC (Global Ocean Ecosystem Dynamics) program examined zooplankton populations and their predators in four coastal marine ecosystems. Program scientists learned that environmental co...
Coastal Transport Processes Affecting Inner-Shelf Ecosystems in the California Current System
California Current System Processes Affecting Inner-Shelf Ecosystems
2015/7/16
Wind-driven upwelling is weak and intermittent in the Southern California Bight, a region sheltered from the strong, prevailing equatorward winds typical of most of the California Current System. Thus...

Ghost cat cat puma tupi predators habitat
2015/7/7
The ghost cat, it's been called, this feline that roams backcountry from the Yukon to Chile. It has dozens of names, from panther, to puma, to mountain lion. But its best descriptor, perhaps, is couga...
Fluorescence spectroscopy opens new windows into dissolved organic matter dynamics in freshwater ecosystems: A review
dissolved organic matter dynamics A review
2014/4/17
The biochemical composition of dissolved organic matter (DOM) strongly influences its biogeochemical role in
freshwater ecosystems, yet DOM composition measurements are not routinely incorporated int...
Nitrogen as the limiting nutrient for eutrophication in coastal marine ecosystems: Evolving views over three decades
Nitrogen marine ecosystems
2014/4/30
The first special volume of Limnology and Oceanography, published in 1972, focused on whether phosphorus
(P) or carbon (C) is the major agent causing eutrophication in aquatic ecosystems. Only ...
Anthropogenic and climatic influences on the eutrophication of large estuarine ecosystems
Anthropogenic climatic infl uences
2014/4/30
We examined the effects of anthropogenic and climatic perturbations on nutrient–phytoplankton interactions and
eutrophication in the waters of the largest estuarine systems in the U.S.A., the Chesape...
Nutrient and light availability regulate the relative contribution of autotrophs and heterotrophs to respiration in freshwater pelagic ecosystems
Nutrient light availability regulate the relative contribution
2014/4/23
In this study, two main hypotheses were addressed. (1) Bacteria contribute proportionally less than autotrophs to
ecosystem respiration as trophic status increases. This hypothesis was examined in a ...
Seasonal dynamics of coastal ecosystems and export production at high latitudes: A modeling study
export production coastal ecosystems
2014/5/30
Export of organic matter from the surface to deeper waters often shows much smaller seasonal variations than
primary production or nitrate-based new production in mid- to high-latitude marine systems...
