How does the killer algae affect the environment?
Threat(s): This fast-growing algae has been dubbed “killer algae” because it crowds out other plants and animals as it colonizes an area with great monotypic stands of vegetation.

Mat-forming invasive species such as C. taxifolia change the habitats where they invade, and as benthic invertebrates are sensitive to environmental disturbance, important sublethal effects on native species may occur (Gribben and Wright, 2006a). L arge monospecific meadows have vastly reduced native species diversity and fish habitat.
