Although recent articles state that jellyfish populations are increasing, most available
evidence shows that jellyfish abundances fluctuate with climatic cycles. Reports of …

Human populations have been concentrated along and exploiting the coastal zones for
millennia. Of regions with the highest human impacts on the oceans, 6 of the top 10 have …

By the pulsed nature of their life cycles, gelatinous zooplankton come and go seasonally,
giving rise in even the most undisturbed circumstances to summer blooms. Even …

Medusae, siphonophores and ctenophores (here grouped aspelagic coelenterates') interact
with fish in several ways. Some interactions are detrimental to fish populations, such as …

Much speculation and some evidence suggest that jellyfish and ctenophore populations
have increased in recent decades. Unfortunately, few past records exist with which to …

There has been a dramatic increase in jellyfish biomass over the eastern Bering Sea shelf
since the early 1990s, which was previously hypothesized to have been triggered by …

The native habitats of the ctenophore, Mnemiopsis, are temperate to subtropical estuaries
along the Atlantic coast of North and South America, where it is found in an extremely wide …

Although eutrophication is a widespread problem in marine waters, its effects are often
difficult to separate from normal fluctuations of pelagic coelenterate populations and from …

A hypothesis is discussed that relates the production of large blooms of jellyfish (medusae
and/or ctenophores) to specific food chains in the sea that are based on the production of …

Over recent decades, man's expanding influence on the oceans has begun to cause change
in some regions, including in the Mediterranean Sea. New proliferations of jellyfish may be …
