Takapotoweb

Carbon flux matrix of the Takapoto atoll planktonic food web
as reconstructed by inverse modelling by Niquil et al. (1998). 
The Takapoto Atoll lagoon is located in the French Polynesia of the
 South Pacific 
The food web comprises 7 functional compartments:<ul>
<li>Phytoplankton</li>
<li>Bacteria</li>
<li>Protozoa</li>
<li>Microzooplankton</li>
<li>Mesozooplankton</li>
<li>Detritus</li>
<li>Dissolved organic carbon (DOC)</li>
</ul>and three external compartments/sinks:<ul>
<li>CO2</li>
<li>Sedimentation</li>
<li>Grazing</li>
</ul>These compartments are connected with 32 flows.
 Units of the flows are mg C/m2/day

datasets

Visualises simple graphs (networks) based on a transition matrix, utilities to plot flow diagrams,
visualising webs, electrical networks, etc.
Support for the book "A practical guide to ecological modelling -
