Lakes and reservoirs as regulators of carbon cycling and climate
- L. Tranvik, J. Downing, G. Weyhenmeyer
- Environmental Science
- 1 November 2009
We explore the role of lakes in carbon cycling and global climate, examine the mechanisms influencing carbon pools and transformations in lakes, and discuss how the metabolism of carbon in the inland…
Nutrient Cycling by Animals in Freshwater Ecosystems

- Environmental Science
- 1 November 2002
This work has shown that nutrient translocation by relatively large animals may be particularly important for stimulating new primary production and for increasing nutrient standing stocks in recipient habitats.
Detritus, trophic dynamics and biodiversity
Traditional approaches to the study of food webs emphasize the transfer of local primary productivity in the form of living plant organic matter across trophic levels. However, dead organic matter,…
Stoichiometry of nutrient recycling by vertebrates in a tropical stream: linking species identity and ecosystem processes
- M. Vanni, A. Flecker, J. Hood, J. L. Headworth
- Environmental Science, Biology
- 10 March 2002
Variation in the rates and ratios at which 28 vertebrate species recycled nitrogen and phosphorus in a tropical stream supports stoichiometry theory and illustrates a strong linkage between species identity and ecosystem function.
Nitrogen and phosphorus recycling by the zebra mussel (Dreissena polymorpha) in the western basin of Lake Erie
- Diane L. Arnott, M. Vanni
- Biology
- 1 March 1996
Comparison of zebra mussel P recycling rates on a basin-wide scale with other P sources suggests that mussels are a major factor in the recycling and flux of P in the western basin of Lake Erie.
Nitrogen and phosphorus excretion by detritivorous gizzard shad in a reservoir ecosystem
- M. Schaus, M. Vanni, T. E. Wissing, M. Bremigan, J. Garvey, R. Stein
- Environmental Science
- 1 September 1997
The results indicate that nutrient excretion by detritivorous fish can be an important source of nutrients to open waters, especially when other sources of nutrients are reduced.
Fish distributions and nutrient cycling in streams: can fish create biogeochemical hotspots?
- P. McIntyre, A. Flecker, M. Vanni, J. Hood, B. W. Taylor, S. Thomas
- Environmental ScienceEcology
- 1 August 2008
The spatial distribution of fish could indeed create hotspots of nutrient recycling during the dry season in this species-rich tropical stream, and the prevalence of patchy distributions of stream fish and invertebrates suggests that hotspot of consumer nutrient recycling may often occur in stream ecosystems.
Ecosystem respiration: Drivers of daily variability and background respiration in lakes around the globe
- C. Solomon, Denise A. Bruesewitz, G. Zhu
- Environmental Science
- 1 May 2013
We assembled data from a global network of automated lake observatories to test hypotheses regarding the drivers of ecosystem metabolism. We estimated daily rates of respiration and gross primary…
Dissolved and particulate nutrient flux from three adjacent agricultural watersheds: A five-year study
- M. Vanni, W. Renwick, J. L. Headworth, Jeffery D. Auch, M. Schaus
- Environmental Science
- 1 May 2001
Fluxes of dissolved and particulate nitrogen (N) and phosphorus(P) from three adjacent watersheds were quantified with ahigh-resolution sampling program over a five-year period. The watershedsvary by…
Phytoplankton primary production and photosynthetic parameters in reservoirs along a gradient of watershed land use
- Lesley B. Knoll, M. Vanni, W. Renwick
- Environmental Science
- 1 March 2003
We investigated how watershed land use (a gradient of agricultural vs. forested land) relates to phytoplankton primary production (PPr) and photosynthetic parameters in 12 reservoirs in Ohio and…
