Potentially harmful microalgae found “rafting” in the EAC
Among the thousands of microalgal species that inhabit our oceans some produce toxins harmful to human health.
- Potent toxins produced by some microalgae can accumulate in the food web and, when consumed by humans, cause serious illnesses
- Scientists tested the hypothesis that forms of these microalgae, usually found attached to surfaces, may be able to expand their range by being transported via seaweed “rafts” in the East Australian Current
The range of some of these marine microorganisms is expanding but, until now, exactly how those forms usually attached to surfaces might disperse has remained largely unknown.
An opportunity to test the hypothesis that harmful surface associated microalgal species could travel long distances using seaweed and seagrass “rafts” has confirmed that the East Australian Current (EAC) is more than a “highway” for Nemo and friends.
