Msg for Willem N. Ellis and others interested
in wild bees vs honeybees.
 
The four references provide by Gene Spears
potentially provide an easy access to the
current literature on the subject, e.g. a
Dialog computer search could produce all
the papers from the scientific literature
which cite these papers.  Or a manual search
can be done with Science Citation Index,
hard copies of which should be available
in most university libraries.
