Exploring the implications of the stoichiometric modulation of planktonic predation
Ecology involves the transfer of elements between organisms and the environment. Inevitably, and as exemplified in ‘stoichiometric ecology’, imbalances in the transfer pathways have potential to disturb trophic dynamics. It is also clear, though, that those disturbances are not simply (linearly, so...
