To date, SIGMEA partners have published more than 100 refereed papers on issues associated with gene flow, coexistence and gene detection and further papers are being submitted for publication. In addition, SIGMEA has contributed to book chapters on GMO issues, European and National government reports and public debates.

SIGMEA has been directly involved in the organization of the conferences on coexistence (GMCC05 in Montpellier, GMCC07 in Seville and GMCC09 in Melbourn, see
