The 12th INTECOL International Congress of Ecology (INTECOL 2017), http://www.intecol2017.org, will be held on August 20-25, 2017, in Beijing, China. The theme of this meeting is “Ecology and Civilization in a Changing World”. With this theme, the major goals are to strengthen communication and cooperation among ecologists around the world, to provide a platform for scientists from different disciplines to discuss about recognized and potential changes of ecology and civilization at local to global scales, and strategies of human society to adapt to these changes. Scientists from all over the world are welcome to join the congress. Call for Symposia To promote collaboration and interdisciplinary dialogue, you are invited to propose symposia with specific topics. Proposals are encouraged to address the congress theme, if appropriate, but doing so is not necessary. Any timely and coherent subject of broad ecological interests will be considered. Proposals that explore interdisciplinary connections with areas of social and natural science outside of ecology are also welcome. Each symposium should have 8 to 10 speakers (15 min. presentations plus 5 min. discussions). The content of symposium should follow the form given in the attachment. The deadline for symposium submission is June 1, 2016. Please submit your proposals to intecol2017(a)rcees.ac.cn and liding(a)rcees.ac.cn using the attached application form.
