Nutrient Limitation of Upper Great Lakes Periphyton across Large Spatial and Environmental Gradients
… as ash-free-dry weight showed simultaneous colimitation of nitrogen and phosphorus in Lake Superior, but was not limited by nutrients in northern Lake Michigan or Green Bay. Periphyton in more eutrophic sites had higher biomass, were more enriched in δ15N, displayed lower C:N, and were …

Development of a cell flux model and its application to nitrogen fixers
… and use it simulate and study light and nutrient colimitation of Synechococcus spp. as observed in published continuous culture studies. In order to capture the observed variations in elemental composition with light and resource availability, we resolve the macromolecular composition of the …
