Tiny Shells Indicate Big Changes to Global Carbon Cycle
Tiny Shells Indicate Big Changes Global Carbon Cycle
2017/7/20
Experiments with tiny, shelled organisms in the ocean suggest big changes to the global carbon cycle are underway, according to a study from the University of California, Davis. For the stud...
Ocean acidification may cause dramatic changes to phytoplankton
Ocean acidification cause dramatic changes phytoplankton
2015/8/4
Oceans have absorbed up to 30 percent of human-made carbon dioxide around the world, storing dissolved carbon for hundreds of years. As the uptake of carbon dioxide has increased in the last century, ...
Protein identified in certain microalgae changes conversation about climate change（图）
Protein identified microalgae changes conversation climate change
2015/6/18
Adrian Marchetti and his team of oceanographers in UNC-Chapel Hill’s College of Arts and Sciences have identified — for the first time — that a protein called proteorhodopsin could allow a major group...
Volunteer divers from The University of Queensland’s Underwater Club have began their descent on the North Stradbroke Island Point Lookout dive sites, to measure changes in plant and animal life over ...
Survival probability of larval sprat in response to decadal changes in diel vertical migration behavior and prey abundance in the Baltic Sea
Survival probability of larval sprat decadal changes in diel vertical migration behavior prey abundance Baltic Sea
2014/4/17
We employed a coupled three-dimensional biophysical model to explore long-term inter- and intra-annual variability in the survival of sprat larvae in the Bornholm Basin, a major sprat spawning area in...
Carbon acquisition byTrichodesmium: The effect of pCO2and diurnal changes
Carbon acquisition Trichodesmium pCO2 diurnal changes
2014/4/18
We investigated carbon acquisition by the N2-fixing cyanobacterium TrichodesmiumIMS101 in response to CO2levels of 15.1, 37.5, and 101.3 Pa (equivalent to 150, 370, and 1000 ppm). Inthese acclimations...
Seasonal changes of bacterial and archaeal communities in the dark ocean: Evidence from the Mediterranean Sea
bacterial and archaeal communities dark ocean
2014/4/17
The study site located in the northwestern Mediterranean Sea was visited nine times in 2005–2006 to collect
water samples from the epipelagic (5 m), mesopelagic (200 m, 600 m), and bathypelagic (1000...
Seasonal changes in planktonic bacterivory rates under the ice-covered coastal Arctic Ocean
Seasonal changes planktonic bacterivory rates the ice-covered coastal Arctic Ocean
2014/4/21
Bacterivory was determined in surface waters of Franklin Bay, western Arctic, over a seasonal ice-covered period (winter-spring, 2003-2004). The objectives were to obtain information on the functionin...
Population dynamics of a freshwater calanoid copepod: Complex responses to changes in trophic status and climate variability
Population dynamics a freshwater calanoid copepod Complex responses changes in trophic status climate variability
2014/4/21
The long-term dynamics of the calanoid copepod Eudiaptomus gracilis were analyzed in Lake Constance, a deep lake that has been influenced strongly by changes in trophic status and climate variability ...
Long-term changes in abundance and diversity of macrophyte and waterfowl populations in an estuary with exotic macrophytes and improving water quality
Long-term changes in abundance diversity of macrophyte waterfowl populations in an estuary exotic macrophytes improving water quality
2014/4/22
We assessed species-specific coverage (km2) of a submerged aquatic vegetation (SAV) community in the fresh and upper oligohaline Potomac Estuary from 1985 to 2001 using a method combining field observ...
Acclimation to a dynamic irradiance regime changes excessive irradiance sensitivity of Emiliania huxleyi and Thalassiosira weissflogii
irradiance regime changes excessive irradiance sensitivity Emiliania huxleyi Thalassiosira weissflogii
2014/4/22
Effects of fluctuating irradiance regimes on excessive photosynthetically active radiation (PAR) and ultraviolet (UV) radiation sensitivity were assessed for Emiliania huxleyi (Lohman) and Thalassiosi...
Changes in microcystin production in cyanobacteria exposed to zooplankton at different population densities and infochemical concentrations
microcystin production cyanobacteria exposed to zooplankton different population densities infochemical concentrations
2014/4/22
We investigated microcystin (MC) production by four cyanobacterial strains (three Microcystis aeruginosa and one Planktothrix agardhii) in response to different grazer densities (direct exposure: zero...

Bioturbation changes the patterns benthic emergence zooplankton
2014/4/21
We investigated the effects of two functionally different deposit feeders, the amphipod Monoporeia affinis and the bivalve Macoma balthica, on the benthic emergence of copepods (Acartia spp., Eurytemo...
Changes in carbon stable isotope ratios during periphyton development
carbon stable isotope ratios periphyton development
2014/5/5
Stable isotopes are widely used to infer trophic relationships with little attention paid to temporal variability at the base of the food web. We examined changes in the carbon-stable isotope composit...
