HABs are a worldwide phenomenon
requiring an international understanding
leading ultimately to local and regional
solutions
HABs: result from noxious and/or toxic algae
that cause direct and indirect negative impacts
to aquatic ecosystems, coastal resources, and
human health

A case study: Ostreopsis blooms * apparently increasing in temperate waters? * biogeographic expansion with climate change?
Objective: To develop a HABs Mandala, the elements are part of the solution

A case study: Ostreopsis blooms
Macroalgae NW Mediterranean
July 2014
Impacts on human health: * Food-borne poisonings in the tropics (palytoxin) * Mild respiratory irritations in temperate beaches Environmental impacts: * Massive benthic fauna mortalities * Water quality deterioration
