We measured the nutrient stoichiometry of inputs, outputs, retention, storage, and recycling in three seasonally
nitrogen (N)-deficient reservoirs by incorporating watershed mass balances with measur...
Hypoxic events stimulate nitrogen recycling in a shallow salt-wedge estuary: The Yarra River estuary, Australia

In a multilake experiment, we found little effect of nutrient excretion by zooplanktivorous fish, but a large effect
of herbivorous zooplankton, on phytoplankton biomass and phosphorus (P) limi...
