Biologists worldwide subscribe to the healthy herds hypothesis, the idea that predators can keep packs of prey healthy by removing the weak and the sick. This reduces the chance disease will wipe out the whole herd, but could it be that predators can also make prey populations more susceptible to other predators or even parasites? Biologists at the Georgia Institute of Technology have discovered at least one animal whose defenses against a predator make it a good target for one opportunistic...

There are many different kinds of crustaceans, ranging from the shellfish Swedish people eat at traditional crayfish parties every August to tiny relatives found in their millions in both freshwater and saltwater. One of the latter, Daphnia pulex, is the first crustacean to have its genome sequenced. A researcher from the University of Gothenburg has made a surprising discovery. The sequencing has been done in an international research network known as the Daphnia Genomics Consortium. The...

Scientists have mapped the genome of the waterflea, revealing the most gene-packed animal characterized to date. The information deciphered of the tiny crustacean could help researchers develop and conduct real-time monitoring systems of the effects of environmental remediation efforts. The waterflea, or the Daphnia pulex, is considered a keystone species in freshwater ecosystems and is roughly the size of an equal sign on a keyboard.  The Daphnia pulex is the first crustacean to have...

Some tiny crustaceans living in clear-water alpine ponds high in Washington state's Olympic Mountains have learned how to cope with the sun's damaging ultraviolet rays without sunblock "“ and with very little natural pigmentation to protect them. In fact, in laboratory tests these water fleas, about the size of fruit flies, withstood UV rays much better than the same species of flea taken from a pond less than a mile away, where the water was murkier and thus offered protection. "The...

A new study co-authored by professor Kam Tang of the Virginia Institute of Marine Science reveals that tiny aquatic organisms known as "water fleas" play an important role in carrying hitchhiking bacteria to otherwise inaccessible lake and ocean habitats. The article, "Bacteria dispersal by hitchhiking on zooplankton," appeared in the June 29 issue of the Proceedings of the National Academy of Sciences. It was co-authored by scientists from the Leibniz-Institute of Freshwater Ecology and...

Of all the things that might control the onset of disease epidemics in Michigan lakes, the shape of the lakes' bottoms might seem unlikely. But that is precisely the case, and a new BioScience report by scientists from Indiana University Bloomington and four other institutions explains why. "In the paper, we go through several explanations for what is going on," said IU Bloomington biologist Spencer Hall, the report's lead author. "We are looking at the zooplankton that is infected, the fish...

SACRAMENTO, Calif., July 9 /PRNewswire-USNewswire/ -- The California Rangeland Trust is pleased to announce the permanent conservation of the 2,918-acre Ichord Ranch, owned by Paul Ichord, in Merced County. Funding from the California Wildlife Conservation Board purchased a conservation easement to conserve rolling grasslands with a high density of vernal pools and associated rare and endangered species. The conservation easement will ensure the existing habitat will continue to be managed...

Boreal forest lakes suffer from 'aquatic osteoporosis,' Queen's-York research team suggests A new and insidious environmental threat has been detected in North American lakes by researchers from Queen's and York universities. Along with scientists from several Canadian government laboratories, the team has documented biological damage caused by declining levels of calcium in many temperate, soft-water lakes. Calling the phenomenon "aquatic osteoporosis," Queen's PhD candidate Adam Jeziorski,...

Wildlands, Inc. is pleased to announce the opening of Laguna Terrace East Conservation Bank in Sacramento County, California. The 200-acre Laguna Terrace East Conservation Bank will permanently preserve habitat for endangered and threatened vernal pool species and the state threatened Swainson's hawk. Conservation bank credits are available now to be purchased by the development community and public sector to fulfill obligations required under federal, state, and county regulations such...

By Kim Martineau, The Hartford Courant, Conn. Jul. 5--NEW HAVEN -- -- A Yale scientist who recently rediscovered a rare type of fairy shrimp in a woodland pool is asking the state to put the tiny critter on its endangered species list. Eubranchipus holmani may never capture the popular imagination the way the imperiled polar bear or red panda have. But biologist Eric Lazo-Wasem hopes his petition will give this homely crustacean and the freshwater pools it calls home some protection....

Vernal Pool Tadpole Shrimp, Lepidurus packardi
2014-04-11 11:50:16

The vernal pool tadpole shrimp (Lepidurus packardi) is a species of shrimp that can be found in California and southern areas of Oregon. Its range includes the Agate Desert in Oregon and many areas in California including the Central Coast, the San Joaquin and Sacramento Valleys, and the southern foothills of the Sierra Nevada. This species prefers to reside in vernal pools, which are now rare, but it can be found in other freshwater habitats including ditches, reservoirs, and ponds. The...
