We are very pleased to invite you to participate in the Meeting of the SIL Plankton Ecology Group—PEG 2015 , which will be held in Guangzhou, China, on 20－24 November, 2015. PEG2015 will be organized by Jinan University. Following the tradition of Plankton Ecology Group in SIL, PEG2015 will bring together freshwater ecologists working on different aspects of freshwater plankton ecology and offer an open platform for deep discussion and exchange of ideas between plankton ecologists from diverse waters and regions. As usual, PEG2015 will be organized around invited lectures linking to each of the different themes, and oral and poster presentations. Each day is centred around a different theme linked to bloom development. The plenary discussion will be specially organized to transfer state-of-the art information to young scientists and students. We also offer a platform for students to present orals and posters, where they will get feedback on their scientific research and presentation skills from senior scientists. For each theme, we invite two speakers to give plenary presentations. Apart from themes on ecological theory relating to bloom development, we will highlight a theme on monitoring, modeling, early warning and management of freshwater blooms , where we will try to bring ecological theory and methods to practical application in mitigation and management of blooms. To encourage the future generation of ecologists, the two best oral student presentation and three best student posters will be highlighted by the scientific committee. A selection of the meeting papers reflecting the different themes of the meeting will be published as a special issue in an international journal. The Meeting of the SIL Plankton Ecology Group — PEG2015 is the first to be organized in China. The organizer — Jinan University is a special university in China. It is the first university established by the state in 1906 by the Qing Government to offer education to overseas Chinese and a long tradition for international exchange. The city — Guangzhou is the biggest one in southern China, modern but at the same time rich in Chinese traditional culture. Only 150 km away from Hong Kong and Macao, Gungzhou is easily connected to the other parts of China and the world.
