New Genetic Study Of Tadpole Shrimps Casts Doubt On The Validity Of The Term 'Living Fossil'
2013-04-02 08:10:15

PeerJ The term 'living fossil' has a controversial history. For decades, scientists have argued about its usefulness as it appears to suggest that some organisms have stopped evolving. New research has now investigated the origin of tadpole shrimps, a group commonly regarded as 'living fossils' which includes the familiar Triops. The research reveals that living species of tadpole shrimp are much younger than the fossils they so much resemble, calling into question the term 'living...

Is It Possible For A Tropical Water Flea To Invade European Lakes?
2013-03-19 11:11:48

Pensoft Publishers Experiments predict that populations of native European species may be substantially suppressed by the invader Daphnia is a genus of small, planktonic crustaceans, commonly called 'water fleas' because of their jumpy swimming style and their size (between 0.2 and 5 mm). They live in various aquatic environments, ranging from acidic swamps to freshwater lakes, ponds, streams and rivers. Species of the genus Daphnia play a key role in freshwater food webs: they consume...

Evolution Of Complex Brains
2012-10-11 04:52:39

April Flowers for redOrbit.com - Your Universe Online Anatomically complex brains evolved earlier than previously thought and have changed little over the course of time, according to a new study by University of Arizona neurobiologist Nicholas Strausfeld. The specimen described in the study, which will be published in the October 11 issue of Nature, is the earliest known fossil to show a brain. The three inch long fossil was discovered embedded in mudstones deposited during the...

Tadpole shrimp are pests of rice production systems in California and have recently been found impacting Missouri and Arkansas rice fields. The shrimp feed on rice seedlings and uproot them during foraging, and their foraging behavior causes water to become muddy, which reduces light penetration to submerged seedlings and delays the development of the rice plant. In "Review of a New Pest of Rice, Tadpole Shrimp (Notostraca: Triopsidae), in the Midsouthern United States and a Winter...

Environmental change is the selective force that preserves adaptive traits in organisms and is a primary driver of evolution. However, it is less well known that evolutionary change in organisms also trigger fundamental changes in the environment. Yale University researchers found a prime example of this evolutionary feedback loop in a few lakes in Connecticut, where dams built 300 years ago in Colonial times trapped a fish called the alewife. In a study published May 23 in the journal...

Less resistance can sometimes be better than more--at least in a freshwater lake When battling a deadly parasite epidemic, less resistance can sometimes be better than more, a new study suggests. A freshwater zooplankton species known as Daphnia dentifera endures periodic epidemics of a virulent yeast parasite that can infect more than 60 percent of the Daphnia population. During these epidemics, the Daphnia population evolves quickly, balancing infection resistance and reproduction....

When it comes to battling a deadly parasite epidemic, it may be better not to fight it.  A new study of freshwater zooplankton suggests less is more when it comes to evolving against a parasitic epidemic. The zooplankton, known as Daphnia dentifera, has been found to endure a yeast parasite infection known to affect more than 60% of its population. What scientists found interesting is how quickly the Daphnia population evolves, balancing infection, resistance, and reproduction....

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...

  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
