By Henry Workman Marine Science Today Writer Species of jellyfish provide greater competition for more complex organisms than previously thought. Recent research published in Science reveals that in areas where plankton-feeding fish populations have dropped off, mostly due to overfishing, jellyfish that occupy a similar ecological niche have taken their places. The jellyfish populations have [...]
Massive amounts of jellyfish have forced the shutdown of nuclear power plants in Japan, Scotland and Israel in the past few weeks. All of these nuclear power plants use seawater to cool its reactors. Marine life is constantly being sucked in by the coolers, but now hundreds of jellyfish are invading the cooling systems causing [...]
A new study by the researchers at the Virginia Institute of Marine Science (VIMS) revealed that jellyfish have a more significant impact than just irritating swimmers in the Chesapeake: they are drastically changing the marine food webs by shifting food energy away from fish towards bacteria. The frequency and size of jellyfish blooms in coastal and [...]
Scientists believe climate change and its oceans warming are to be blamed for jellyfish overpopulation, expanding their ranges and appearing earlier in the year.
A new research presents convincing evidence that jellyfish overpopulation is associated with over-fishing and excess nutrients, a result of human activities.
