for the recognition of food plants for the
caterpillars in our forest. And also of the
sale of our pictures in the Central African
Republic and for export. We would make
ourselves known all over the world. It is
possible. This solution would be a relief
for us. It would put an end to discussion
of a law that would be difficult to apply
and would make our work sustainable.
And in addition to conserving the various
species of butterflies, we would learn a
lot about their biology.
Samples of termite nests from the
Sangha scientific expedition were brought
to University Paul Sabatier (Toulouse, France).
The nest stands upright on the soil like a
mushroom, and its gallery system extends
into the surrounding soil towards the different
food sources.
Centre de Recherche sur la Cognition Animale
(CRCA) is analysing their structure and growth,
using X-ray tomography. Scientists obtained
this image network representation where each
chamber is mapped to a node and each tunnel
to an edge. This network is sparsely connected, but
the edges are chosen such as to keep the distances
between any two nodes very short. This study could be
