Dear Colleagues,

We have had the great honour of organizing this symposium within the XVI OPTIMA Meeting.

The aim of the symposium will be to explore Mediterranean algal diversity, looking into diverse aspects (e.g. systematic, ecology, biodiversity changes). We will host 5 invited speakers and there will also be the opportunity to present poster contributions (e-posters).

Talks will be given in English or in French, the official languages of the Meeting.

We now welcome any proposals for poster contributions. Proposals, including a definitive title, name(s) of the author(s), institution(s), a short description of the contribution (no more than 10 lines), e-mail contact address, should be sent by 20 March 2019 both to Anna Maria Mannino (e-mail: and Sotiris Orfanidis (e-mail:

For accepted proposals, for which a notification of acceptance will be sent to the author’s e-mail address, the definitive abstract should be submitted by 20 June 2019. Please, consult the second circular (available on the section “Documents” of the website) for abstract submission rules and other useful information.

We invite you to join us and to enjoy with us this great international appointment.
