The dissolved organic carbon (DOC) pool on tropical coral reefs is mainly fueled by photosynthates released from benthic primary producers (BPP), such as reef algae and scleractinian corals. DOC concentrations near BPP have repeatedly been observed to be elevated...

Here we present a single working model that attempts at reconciliation of biological systems. To do this we recognize and emphasize a universal theme of all biological systems: a need for resources. That is, we consider the dynamics of resource allocation as a...
