Document Summary
Impacts on human health and welfare: malaria. Although plasmodium is arguably the best studied of all protists, researchers have still not been able to devise effective and sustainable measures to control it: harmful algal blooms. Algal blooms can be harmful to people because clams and other shellfish filter photosynthetic protists out of the water as food. During a bloom, high levels of toxins can build up in the flesh of these shellfish. Ecological importance of protists: protists play a key role in equatic food chains. Some researchers hypothesize that when these blooms occur, the amount of carbon that rains down into carbon sinks in the form of shells and dead cells may increase. Fertilizing the ocean to promote blooms might be an effective way to reduce co2 concentrations in the atmosphere. Discovering new lineages via direct sequencing: subsequent work has confirmed the existence of many, diverse species of protists that are less than . 2 m in diameter.
