The theme of IPC 11 will be “Challenges of the molecular era for algal research and the promise of bioprospecting”, but as usual, contributions on all aspects of phycology will be welcome. The Congress will have the usual format, with a mixture of plenary talks, symposia and contributed sessions (of talks and posters) on four days, and a midweek break and excursions. Pre and post-congress excursions will be available. There will also be opportunities to run Workshops in association with the Congress: anyone interested in doing so should contact the convener as soon as possible. For further information, please visit the IPC 11 WEBSITE http://ipc11.intphycsoc.org, where the first circular and other information will be accessible by October 1st 2016.
