Aggressive algae injure and kill competitors to gain access to their cells' nutrients, similar to blood-sucking insects. This behavior may be a key mechanism in the formation of toxic plankton blooms.
Researchers predict a moderately large red tide outbreak in the Gulf of Maine this spring and summer, with toxicity levels expected to be smaller than last year's bloom. The potential for an extensive outbreak depends on weather events and oceanographic conditions, making it difficult to make precise predictions.
A massive 'red tide' bloom caused seabirds to lose their waterproof insulation, leading to hypothermia and starvation. Researchers found a surfactant in the foam that stripped the birds' feathers of their natural oils.
