Atmospheric deposition of nitrogen and phosphorus in the annual nutrient load of Lake Tahoe (California‐Nevada)
Atmospheric deposition provides most of the dissolved inorganic nitrogen (DIN) and total nitrogen in the annual nutrient load of Lake Tahoe. Deposition also contributes significant amounts of soluble…

Phytoplankton nutrient deficiency as related to atmospheric nitrogen deposition in northern Minnesota acid-sensitive lakes
The Northern Lakes and Forests ecoregion of Minnesota contains thousands of lakes, characterized by their sensitivity to acid rain and typically low productivity. Four acid-sensitive lakes were…

Seasonal Pathogen Removal by Alternative On‐Site Wastewater Treatment Systems
TLDR
Subsurface-flow constructed wetlands, sand filters, and peat filters near Duluth, Minnesota, were studied to determine their seasonal performance for removing pathogens from wastewater and fecal coliform removal patterns reflected those for Salmonella by treatment systems for summer and winter periods.

Ecological effects of mosquito control on zooplankton, insects, and birds
TLDR
The lack of close coupling between zooplankton, insects, and breeding birds probably reflects the ecological complexity of these wetlands such as the presence of other limiting factors on population distribution and abundance.

Human Influences on Water Quality in Great Lakes Coastal Wetlands
TLDR
Strong evidence is provided of the link between water chemistry and human stress in Great Lakes coastal wetlands and can be used to inform management efforts to improve water quality in Great lakes coastal ecosystems.

Nitrate uptake by phytoplankton and periphyton: Whole‐lake enrichments and mesocosm‐15N experiments in an oligotrophic lake
Periphyton nitrate uptake and denitrification, not phytoplankton assimilation, accounted for -90% and 73% of the depletion of - 35 pg N03-N liter-l added as whole-epilimnion enrichments of ammonium…

Dynamics of dissolved organic nitrogen in subalpine Castle Lake, California
Dissolved organic nitrogen (DON) concentrations were measured in meso-oligotrophic Castle Lake, California during the ice-free season in 1982, 1983 and 1984. No consistent relationships were found…

Molybdenum limitation of microbial nitrogen assimilation in aquatic ecosystems and pure cultures
TLDR
It is suggested that meter-scale Mo and oxygen depth profiles from Castle Lake are consistent with the hypothesis that nitrogen-fixing cyanobacteria in freshwater periphyton communities have higher Mo requirements than other microbial communities, and topics for future research related to Mo bioavailability through time and with changing oxidation state are presented.

Turbidity Tolerances of Great Lakes Coastal Wetland Fishes
Abstract Despite recent interest in assessing the condition of fish assemblages in Great Lakes coastal wetlands and a concern for increasing turbidity as a major stressor pathway influencing these…

Effects of methoprene and Bti (Bacillus thuringiensis var. israelenis) on non-target insects
The effects of mosquito larvicides Bacillus thuringiensis israelensis (Bti) and methoprene, on non-target benthic invertebrates were studied in a divided pond experiment in south-central Minnesota,…
