The 'phytoplankton factory' -- from nutrients to algae growth
phytoplankton ocean ecosystems climate change
2021/8/9
Phytoplankton are the foundation of ocean ecosystems: like rainforests, they consume carbon from the atmosphere, form the basis of the marine food web and have a decisive influence on fish abundance a...
Coexisting in a Sea of Competition Similar Diatom Species Seek Out Nutrients in Different Ways
Diatom Species Seek Out Nutrients Different Ways
2015/4/29
Diversity of life abounds on Earth, and there's no need to look any farther than the ocean's surface for proof. There are over 200,000 species of phytoplankton alone, and all of those species of micro...

Relationships between phytoplankton growth and cell size in surface oceans: Interactive effects of temperature, nutrients, and grazing
phytoplankton growth cell size in surface oceans Interactive effects temperature nutrients grazing
2014/4/17
We compile two data sets from14C uptake and dilution experiments conducted in surface waters of the global ocean to investigate the relationship between phytoplankton mass-specific growth rate and cel...
Influence of water-column depth and mixing on phytoplankton biomass, community composition, and nutrients
Influence of water-column depth mixing on phytoplankton biomass community composition nutrients
2014/4/21
We independently manipulated mixing intensity (strong artificial mixing vs. background turbulence) and water-column depth (2 m, 4 m, 8 m, and 12 m) in order to explore their separate and combined effe...

Variable effects of marine-derived nutrients on algal production in salmon nursery lakes of Alaska during the past 300 years
marine-derived nutrients algal production salmon nursery lakes Alaska during the past 300 years
2014/4/22
We measured historical changes in sedimentary δ15N and fossil pigments in four lakes with anadromous semelparous salmon and two reference lakes to quantify the degree to which the flux of marine-deriv...
Responses in dissolved nutrients and epilithon abundance to spawning salmon in Southeast Alaska streams
dissolved nutrients epilithon abundance spawning salmon Southeast Alaska streams
2014/5/8
Spawning Pacific salmon (Oncorhynchus spp.) historically transported massive quantities of marine-derived nutrients (MDN) into nutrient-poor streams of the Pacific Northwest. In southeast Alaska, we m...
Availability of iron and major nutrients for phytoplankton in the north-east Atlantic Ocean
Availability of iron and major nutrients for phytoplankton in the north-east Atlantic Ocean
2014/5/19
Because of recent findings that Fe is a limiting factor for phytoplankton activity even at relatively high dissolved iron (DFe) concentrations, the potential importance of Fe limitation was revisited ...
Salmon-derived mercury and nutrients in a Lake Ontario spawning stream
Salmon-derived mercury nutrients Lake Ontario spawning stream
2014/5/19
We tested the hypothesis that concentrations of mercury species (Hg) and nutrients (NH4+, NO3-, P, and dissolved organic carbon) in abiotic and biotic components would be altered by the decomposition ...
Response of freshwater microcosm communities to nutrients, fish, and elevated temperature during winter and summer
Response of freshwater microcosm communities nutrients, fish elevated temperature winter and summer
2014/5/20
Under conditions of stress, shallow freshwater ecosystems can undergo a state change characterized by the rapid loss of macrophytes and subsequent dominance of phytoplankton. Elevated water temperatur...
Taxonomic richness of stream benthic algae: Effects of flood disturbance and nutrients
stream benthic algae flood disturbance nutrients
2014/5/27
We sampled benthic algae monthly for 15 months in 12 New Zealand gravel-bed streams to investigate amongstream differences in algal taxonomic richness and how this might relate to among-stream differe...
Impacts of nutrients and grazing mortality on the abundance of Aureococcus anophagefferens during a New York brown tide bloom
nutrients and grazing mortality abundance of Aureococcus anophagefferens a New York brown tide bloom
2014/5/26
Although nutrients and grazing both contribute to the formation of harmful algal blooms, research on these events has rarely considered both factors simultaneously. To ascertain the impact of nutrient...
The effects of nutrients and herbivory on competition between a hard coral (Porites cylindrica) and a brown alga (Lobophora variegata)
The effects of nutrients herbivory on competition a hard coral Porites cylindrica a brown alga Lobophora variegata
2014/5/26
Coral reef degradation often involves a phase shift from coral- to macroalgal-dominated reefs. Declining levels of herbivory or increasing supply of nutrients have both been suggested as a cause of in...
Effects of mineral nutrients on the growth of bacterio- and phytoplankton in two southern reservoirs
mineral nutrients growth of bacteria phytoplankton two southern reservoirs
2014/6/9
Nutrient limitation of bacterio- and phytoplankton was studied simultaneously in two warm-water lakes in the southern United States—Joe Pool Lake (JPL) and Eagle Mountain Lake (EML). Lakes were s...
