Seasonal and spatial patterns in nitrogen cycling and food web interactions in Lake Taupō New Zealand
… interactions in Lake Taupō. First, δ¹⁵N and δ¹³C stable isotope analyses are used to quantify intra-annual patterns in, and drivers of, food web dynamics. The focus is on littoral-pelagic diet coupling by mobile consumers in response to variation in pelagic resource availability. Second, spatially …

Estimating Nitrogen Fixation Rates, Importance, and Short-Term Efficiency in Small, Temperate Reservoirs Using Delta15N Techniques
<p>Nitrogen (N2) fixation can give certain species of cyanobacteria a competitive advantage in lake and reservoir phytoplankton. These species of cyanobacteria, along with others that cannot fix N2, can form toxic compounds that impair water quality when present in high concentrations. N2 fixation …
