Waste Slime Turns Jellyfish Into Ecological Vampires

That waste is useful is one of the animal kingdom’s cardinal principles. One creature’s discards are another’s dinner, and so continues the circle of life. But jellyfish, it would seem, bend the rule.

Their waste is generally inedible, food mostly for a few odd species of bacteria that live just long enough to emit a whiff of CO2, then sink. All that nutrition and energy vanishes with barely a trace.

During a jellyfish bloom, food webs may thus be plucked and rearranged, configured to feed jellies that in turn feed almost nothing. Whether this represents the future of Earth’s oceans depends on whom you ask, but it’s an interesting phenomenon in itself.

“Jellyfish are consuming more or less everything that’s present in the food web,” said Robert Condon, a Virginia Institute of Marine Science and co-author of a jellyfish-impact study published June 7 in Proceedings of the National Academy of Sciences

Your Jellyfish Sting Can Help Science

For most of the 20th century, “fisheries surveys would treat jellyfish as junk,” said Robert Condon of the Virginia Institute of Marine Science. “They would just throw them back.”

In a quest for data, the Monterey Bay Aquarium Research Institute set up Jellywatch , an online service for people to report sightings of jellyfish, algal blooms and local marine conditions . By sharing what they see, citizens can produce large-scale surveys that scientists can’t afford on their own. The database is freely available to researchers and the public.

“If your mom goes to the beach and gets stung, she can record that,” said Condon. “We’re using that as part of our database.”

Condon and his co-authors are part of a research community whose attention has been recently transfixed by jellyfish, which evolved more than 500 million years ago and once dominated Earth’s oceans, but until the late 20th century were of largely esoteric scientific interest.

In the 1990s, however, jellyfish populations exploded in the Bering Sea , rising by a factor of 40 in less than a decade. By the time those blooms subsided, fishermen in the Sea of Japan were accustomed to 500-million-strong swarms of refrigerator-sized, ship-sinking Nomura jellyfish, their numbers unprecedented in recent memory. In the Mediterranean, once-seasonal jellies became a year-round fact of life , again wreaking fisheries havoc.

A new study by Robert Condon of the Virginia Institute of Marine Science and collaborators found that jellyfish blooms can wreak havoc by disrupting ocean food webs. Jellyfish eat the tiny plankton at the base of the ocean food chain.

"Jellyfish are voracious predators," researcher Robert Condon, of the Virginia Institute of Marine Science, said in a prepared statement; and they feast on some of the same plankton that fish eat. That means less food for fish and other higher-level

Robert P. Condon | The Bridgton News

MIDDLEBURY, VT. — Robert Pierce “Bob” Condon, born March 20, 1929 in Dorchester, Mass., the son of John H. Condon Jr. and Nellie (Messenger) Condon, the sixth of Bill, Helen, Carl, Buddy and Richard, all of whom preceded him in death. The family moved to Bedford where Bob went to local schools. After graduating from Lexington High, he enlisted in the Air Force, spending two years in Alaska. He was commissioned Second Lt. in the Air Force, in which he proudly and happily served, joining the Vermont Air Guard and Militia — the socalled backup unit to take over in the event of the Vermont Air Guard being activated. He retired from the Air Force as a Lt. Col. in 1979, from the Air Guard as a Col. in 1989.

After graduating from Boston University with a B.S., B.A in 1956, he began his lifelong career in the personnel field, first at the New England Life Insurance company in Boston, Mass.

While pursuing graduate studies at B.U., he met and married a fellow class member, Margaret Hall, in 1962. He moved to Bedford, continuing his Air Force Reserve duties at Hanscom Field and joining MecroWave Associates in Burlington, Mass.

The family moved to Rutland Town, Vt. when Bob accepted a position as Personnel Director at C.V.P.S. He then accepted the Personnel Director position at Pluess-Staufer-OMYA for the last 20 of his official working years, retiring as Vice President of Human Resources.

During his working years, he was active in society for the advancement of management, Lions and Rotary clubs, started the Bedford Jaycees and Eastern College Placement Officers Assoc. While still in Bedford he was involved in the establishment of the Wedgewood Club, a family-oriented pool and social club. In the early 70s, he and Peg bought the A-frame in Denmark, Maine on Moose Pond, which was the site of summer and winter weekends and vacations for water sports and skiing for the whole family. Bob’s sport was fishing, which he enjoyed with many friends or alone — always seeking that elusive big bass. They retired to Maine and enjoyed ten years in Denmark on beautiful Moose Pond. They returned to Vt. to the Lodge at Otter Creek to enjoy elderly retirement living.

Survivors include his wife Margaret (Peg); his children Ellen (husband Cary Griffin) of Florence, Mo., Anne (partner Dr. Suzie Harris) of So. Burlington, Vt.; and his three grandchildren, Ryan A. Layman of Japan, Kelsey L. Layman of Boston, Mass. and Zelie G. Condon-Layman of So. Burlington, Vt.
