Journal ArticleDOI
A comparison of the abilities of freshwater algae and bacteria to acquire and retain phosphorus1
David J. Currie,Jaap Kalff +1 more
TL;DR: The kinetic data suggest that planktonic bacteria are unlikely to be limited by phosphorus in situ and are consistent with the hypothesis that the bacteria should be markedly superior competitors at natural phosphate concentrations.
Journal ArticleDOI
Nutrient and particulate fluxes in a salt marsh ecosystem: Tidal exchanges and inputs by precipitation and groundwater 1
TL;DR: Waterborne nutrients enter the Great Sippewissctt Marsh through groundwater, rain, and tidal flooding as discussed by the authors, and the amount of waterborne nutrients entering the marsh provides primarily ammonium, nitrate, nitrite, dissolved organic (don) and particulate (PN) nitrogen, particulate carbon (PC), and phosphate.
Journal ArticleDOI
Excretion of organic matter by marine phytoplankton: Do healthy cells do it?1
TL;DR: In this paper, two lines of evidence for excretion are found in the literature: measurements in field studies of organic 14C in productivity experiments and the appearance of organic matter in laboratory culture filtrates.
Journal ArticleDOI
Nitrogen Limitation in a Sonoran Desert Stream
Nancy B. Grimm,Stuart G. Fisher +1 more
TL;DR: Temporal patterns of chlorophyll a accrual suggest that availability of nitrogen limited the rate of algal increase, but not the ultimate periphyton standing crop, so it is proposed that nitrogen limitation is common in the desert Southwest.
Journal ArticleDOI
The impact of climate on the biogeochemical functioning of volcanic soils
Oliver A. Chadwick,Robert T Gavenda,Eugene F. Kelly,Karen Ziegler,Carolyn Olson,W. Crawford Elliott,David M. Hendricks +6 more
TL;DR: In this article, the authors sampled 16 soil profiles along an arid to humid climosequence on Kohala Mountain, Hawaii, and found that weathering and soil properties change in a nonlinear fashion with increased rainfall.
