Multiple Sources and Forms of Nitrogen Sustain Year-Round Kelp Growth on the Inner Continental Shelf of the Santa Barbara Channel
Nitrogen Sustain Year-Round Kelp Growth Santa Barbara Channel
2015/7/16
Forests of the giant kelp Macrocystis pyrifera found on coastal rocky reefs lack the large reservoirs for nutrient storage found in many terrestrial environments. Supporting their high year-round grow...
Sensitivity of Antarctic phytoplankton species to ocean acidification: Growth, carbon acquisition, and species interaction
Growth carbon acquisition species interaction
2014/4/2
Despite the fact that ocean acidification is considered to be especially pronounced in the Southern Ocean, little
is known about CO2
-dependent physiological processes and the interactions of Antarc...
Interactions between limiting nutrients: Consequences for somatic and population growth of Daphnia magna
Interactions between limiting nutrients population growth of Daphnia magna
2014/4/17
To assess the significance of nutrient interactions on animal performance, life-history experiments were
conducted with the freshwater herbivore Daphnia magna in a system with two limiting nutrients ...
Effect of fully characterized unsteady flow on population growth of the dinoflagellate Lingulodinium polyedrum
characterized unsteady dinoflagellate Lingulodinium polyedrum
2014/4/18
Dinoflagellate population growth is inhibited by fluid motion, which is typically characterized by some average
flow property, regardless if the flow is steady or unsteady. This study compares the ef...
Combined effects of food quality and temperature on somatic growth and reproduction of two freshwater cladocerans
Combined effects of food quality somatic growth
2014/4/18
We investigated the effect of food quality on somatic growth and reproduction of zooplankton at different
temperatures (12uC, 15uC, 20uC, and 25uC). Standardized growth experiments of two cladocerans...
The effect of temperature on the coupling between phosphorus and growth in lacustrine bacterioplankton communities
phosphorus growth lacustrine bacterioplankton communities
2014/4/18
Phosphorus (P) routinely limits microbial growth in freshwater ecosystems. The growth rate hypothesis (GRH)
relates growth to biomass P content mechanistically through changes in ribosomal ribonuclei...
Local-scale nutrient regeneration facilitates seaweed growth on wave-exposed rocky shores in an upwelling system
egeneration facilitates seaweed Local-scale nutrient
2014/4/17
This study shows that, even on exposed, wave-swept, rocky shores in a nutrient-replete upwelling ecosystem,
mussels (Mytilus californianus) facilitate the growth of the seaweed Porphyra perforata by ...
Fast growth and turnover of chironomid assemblages in response to stream phosphorus levels in a tropical lowland landscape
Fast growth turnover of chironomid assemblages
2014/4/23
We studied the response of a dominant primary consumer, larval Chironomidae (Diptera), to phosphorus (via a
microbial response) across eight detritus-based streams spanning a gradient in soluble reac...
A role for manganese in superoxide dismutases and growth of iron-deficient diatoms
superoxide dismutases iron-defi cient diatoms
2014/5/19
We have discovered that coastal and oceanic diatoms require more manganese (Mn) to grow in iron (Fe) -deficient
than in Fe-sufficient seawater. At low inorganic concentrations, like those...
Growth rate of the major phylogenetic bacterial groups in the Delaware estuary
Delaware estuary major phylogenetic
2014/5/19
The phylogenetic composition of bacterial communities varies along the salinity gradient of estuaries, one notable
pattern being the prevalence of alpha- and beta-proteobacteria in salt- and freshwat...
Tissue carbon, nitrogen, and sulfur stable isotope turnover in transplanted Bathymodiolus childressi mussels: Relation to growth and physiological condition
Tissue carbon nitrogen sulfur stable isotope turnover transplanted Bathymodiolus childressi mussels growth and physiological condition
2014/5/19
The growth and physiological condition of the methanotrophic hydrocarbon seep mussel Bathymodiolus childressi reflects the habitat quality of the sites it occupies on the seafloor of the upper Louisia...
Bacterial metabolism and growth efficiency in lakes: The importance of phosphorus availability
Bacterial metabolism growth effi ciency
2014/5/14
We investigated bacterial responses to variations in dissolved organic carbon (DOC) and nutrient availability by
a comparative analysis of bacterial metabolism in lakes ranging from oligotrophic to e...
Iron requirements for dinitrogen- and ammonium-supported growth in cultures of Trichodesmium (IMS 101): Comparison with nitrogen fixation rates and iron:carbon ratios of field populations
Iron requirements nitrogen- and ammonium-supported growth cultures of Trichodesmium nitrogen fixation rates and iron field populations
2014/5/21
We quantified the relationships among the specific growth rate, intracellular iron content, and steady state iron uptake rate for cultures of the marine diazotrophic cyanobacterium Trichodesmium (IMS ...
