Nitrogen loading from developed watersheds to aquatic ecosystems can stimulate microbial denitrification, a process that reduces nitrate (NO{ 3 ) to dinitrogen (N2) or nitrous oxide (N2O), the latt...
We conducted a 3-yr study of the population dynamics of the invasive cladoceranBythotrephes longimanusin Island Lake Reservoir (Minnesota) and compared our results to other human-constructed reservoir...
We tested the hypothesis that nutrient sequestration and carbon flow through heterotrophic bacteria is relatively highest in oligotrophic systems and decreases with trophic state in 17 reservoirs in T...
Horizontal dispersion mechanisms must be well defined in order to determine the origin and fate of heterogeneous distributions of biogeochemical material. Here data from an intensive field campaign i...
The highest density of aggregates (1.4 3 103 L21 ) in the hypereutrophic Barra Bonita Reservoir (mean depth of 10.2 m) coincided with the peak population density of the diatom Aulacoseira granulata...
Bacterial biomarkers (D-amino acids and muramic acid) were measured in various organic matter size fractions collected in the North Pacific and North Atlantic, and they were used to quantitatively est...
The cyanobacteriumAnabaena flos-aquaeand many other phytoplankton species have a complex life cycle that includes a resting stage (akinete). We present a new agent-based (also known as individual-base...
Although effects of land use/cover on nutrient concentrations in aquaticsystems are well known, half or more of the variation in nutrient concentration remains unexplained by land use/cover alone. Hyd...
Bacterial biomarkers (D-amino acids and muramic acid) were measured in various organic matter size fractions collected in the North Pacific and North Atlantic, and they were used to quantitatively est...
Results of a field campaign and numerical simulations are used to show how physical mechanisms impose length scales and timescales that determine the dominant biogeochemical process. As an example, t...
We investigated convection caused by surface cooling and mixing attributable to wind shear stress and their roles as agents for the transport of phytoplankton cells in the water column by carrying out...
Light-scattering attributes of minerogenic particles in a reservoir, where these particles dominate over a wide range of light-scattering levels, were characterized by an individual particle analysis ...
To evaluate the effect of reservoir flooding on carbon cycling over time, we studied sedimentary environments in three natural lakes that existed prior to impoundment and that have been incorporated i...
Water withdrawal from Mediterranean reservoirs in summer is usually very high. Because of this, stratification is often continuous and far from the typical two-layered structure, favoring the excitati...
We performed a transplant experiment in eutrophic Sau reservoir to assess the factors that control bacterial abundance, activity, growth rate, and community composition. Samples from the lacustrine an...
