Scientists New Long-Term Ecological Research Results Annual Ocean Sciences Conference
2018/2/1
Are the U.S. East Coast's salt marshes healthy? How do sea ice patterns affect penguin populations in Antarctica? What diet do blue whales off California specialize in? Is every El Niño the same?...
Mass Extinctions Remove Species But Not Ecological Variety（图）
Mass Extinctions Remove Species Ecological Variety
2018/1/31
Sixty-five million years ago, clouds of ash choked the skies over Earth. Dinosaurs, along with about half of all the species on Earth, staggered and died.
But in the seas, a colorful population of ma...
NSF announces new Long-Term Ecological Research sites off Alaska,New England coasts
NSF new Long-Term Ecological Research sites off Alaska New England coasts
2017/3/14
National Science Foundation (NSF) grants will support two new Long-Term Ecological Research (LTER) sites. Scientists will conduct research along the Northeast U.S. continental shelf and in the norther...
Ecological subsidies alter the structure of marine communities
subsidies alter marine communities
2015/12/16
Subsidies are usually the subject of
purely economic debates. They
represent flow of resources from
one economic sector to another
and can be fundamental to competitive
ability of industries in d...
Larval Transport and Coastal Upwelling: An Application of HF Radar in Ecological Research
Larval Transport Coastal Upwelling HF Radar Ecological Research
2015/8/10
For many marine fish and invertebrate species, near-surface currents strongly affect the likelihood of surviving as a planktonic larva and arriving at a suitable location, say, a rocky coastline, a ke...
Connecting Places:The Ecological Consequences of Dispersal in the Sea
Connecting Places Ecological Consequences Dispersal in the Sea
2015/7/22
Few traits are shared by all species of animals and plants. Movement is a noteworthy exception. Although many species seem permanently locked to a particular place, they inevitably move at some stage ...
Coastal Long Term Ecological Research: Introduction to the Special Issue
Special Issue Term Ecological Research
2015/7/16
The US National Science Foundation’s Long Term Ecological Research (LTER) network was established in 1980 to provide the scientific expertise, research platforms,
and long-term data sets necessary t...
Elemental composition of marine Prochlorococcus and Synechococcus: Implications for the ecological stoichiometry of the sea
Elemental composition marine Prochlorococcus Synechococcus ecological stoichiometry
2014/5/21
The elemental composition of marine cyanobacteria is an important determinant of the ecological stoichiometry in low-latitude marine biomes. We analyzed the cellular carbon (C), nitrogen (N), and phos...
Threshold-driven shifts in two copepod species: Testing ecological theory with observational data
Threshold-driven shifts two copepod species Testing ecological theory observational data
2014/4/2
We used an observed abrupt shift in the dominance pattern of two coexisting copepod species in Müggelsee, a shallow eutrophic lake in Germany, to investigate mechanisms leading to this shift, by embed...
Ecological stoichiometry: An elementary approach using basic principles
basic principles Ecological stoichiometry
2014/4/2
Based on the observation that organism-specific elemental content creates ecologically relevant mismatches
such as between plant and animal tissue, it was postulated—and experimentally verified—that ...
Environmental and Ecological Effects Of Ocean Renewable Energy Development: A Current Synthesis
Marine renewable energy carbon emissions the Marine environment
2015/7/7
Marine renewable energy promises to assist in the effort to reduce carbon emissions worldwide. As with any large-scale development in the marine environment, however, it comes with uncertainty about p...
Ecological speciation in a cyclic parthenogen: Sexual capability of experimental hybrids betweenDaphnia pulexandDaphnia pulicaria
Ecological speciation Sexual capability experimental hybrids between Daphnia pulex and Daphnia pulicaria
2014/4/17
Daphnia pulexandDaphnia pulicariaare cyclically parthenogenetic crustaceans that are distributed widelyin North American freshwaters. Hybrids ofD. pulexandD. pulicariaare common in the wild, where pop...
Edge gradients provide evidence of ecological interactions in planktonic thin layers
Edge gradients provide ecological interactions
2014/4/18
Physical, optical, and acoustical data from Monterey Bay, California, USA, describing the distributions of
phytoplankton, zooplankton, and small fish as well as gradients in the physical habitat were...
Assessing ecological responses to catastrophic amphibian declines: Patterns of macroinvertebrate production and food web structure in upland Panamanian streams
Assessing ecological responses catastrophic amphibian declines
2014/4/17
As part of the Tropical Amphibian Declines in Streams (TADS) project, we estimated macroinvertebrate
production and constructed quantitative food webs for four headwater stream reaches in the Panaman...
Ecological, landscape, and climatic regulation of sediment geochemistry in North American sockeye salmon nursery lakes: Insights for paleoecological salmon investigations
sediment geochemistry Ecological landscape climatic
2014/4/17
We used multiple linear regressions across a Northeast Pacific region 56-lake set to examine the influence of
sockeye salmon spawner densities and limnological, climatic, and watershed characteristic...
