The freshwater cyanobacterium Lyngbya wollei forms dense mats in lentic systems throughout the southeastern United States and produces paralytic shellfish poisons (PSPs), such as saxitoxins, that coul...
Coral reef degradation often involves a phase shift from coral- to macroalgal-dominated reefs. Declining levels of herbivory or increasing supply of nutrients have both been suggested as a cause of in...
The effects of herbivory and light on epilithic periphyton from Minor Creek (2,200 m above sea level), a Swiss alpine stream, were examined by manipulating light intensity and the densities of two abu...
The cover of noncoralline macroalgae increased dramatically on Caribbean reefs during the 1980s and 1990s. A top-down hypothesis, based largely on observations at Discovery Bay, Jamaica, is that this ...
