Are Scyphozoan Blooms Increasing? Causes and Consequences
Scyphozoan medusae exhibit important population fluctuations over a variety of time scales. Populations of many species bloom, that is, exhibit a rapid localized population increase, as a natural part of their life cycles; however, blooming events are being reported more frequently.

Scyphozoan medusae exhibit important population fluctuations over a variety of time scales. Populations of many species bloom, that is, exhibit a rapid localized population increase, as a natural part of their life cycles; however, blooming events are being reported more frequently. Anthropogenic impacts that are altering the physical and chemical processes of the ocean, such as overfishing and pollution, are creating environments that favor medusae and may cause increases in their abundance. These trends have been most observed in the Adriatic Sea, Bering Sea, Mediterranean, North Sea, Gulf of Mexico and Sea of Japan. The reports examined in this paper show that scyphozoan species are able to take advantage of conditions created by anthropogenic influences. However, more information about global and long-term trends is needed to clarify whether scyphozoan blooms are truly increasing or not. Limited top-down control of medusae populations has led many to assume that medusae are trophic dead ends. However, medusae have been recognized as important contributors to pelagic food webs, providing inorganic nutrients to primary producers via excretion and serving as prey for turtles, mammals, birds and some fish. It is important to understand scyphozoan life cycles and how they are affected by anthropogenic impacts that may play a role in bloom formation.
