Flexible Partnership Lets Lichens Live In Different Habitats
2013-04-23 15:40:42

Pensoft Publishers Lichens are symbiotic organisms consisting of a fungal partner and one or several algal partners. The association is so close that scientists until 1867 were not aware that lichens actually consist of two different partners. After the Swiss botanist Simon Schwendener discovered the dual nature of lichens, lichenologists were focusing on the fungal partner when studying lichens, since it was often believed that only few algae are involved in the symbiosis. Molecular...

Switching To A Power Stroke Helps A Tiny Marine Crustacean To Survive
2013-04-02 14:29:14

University of Texas at Austin [ Watch the Video Copepod Nauplius Swimming at 10 Degrees C ] Olympic swimmers aren't the only ones who change their strokes to escape competitors. To escape from the jaws and claws of predators in cold, viscous water, marine copepods switch from a wave-like swimming stroke to big power strokes, a behavior that has now been revealed thanks to 3-D high-speed digital holography. Copepods are tiny crustaceans found in nearly every aquatic environment on...

Women with higher circulating carotenoid levels are at a reduced risk of breast cancer according to a study published December 6 in the Journal of the National Cancer Institute Carotenoids, which are micronutrients found in fruits and vegetables, have been found to have anticarcinogenic properties. Previous experimental studies have shown that carotenoids inhibit the tumor progression and reduce proliferation of estrogen receptor—positive (ER+) and estrogen receptor—negative...

Arctic Bacteria Help In The Search To Find Life On Europa
2012-05-31 02:53:51

In a fjord in Canada scientists have found a landscape similar to one of Jupiter's icy moons: Europa. It consists of a frozen and sulphurous environment, where sulphur associated with Arctic bacteria offer clues for the upcoming missions in the search for traces of life on Europa. It is not easy to find a place on Earth where ice and sulphur come together, supposedly like on Europa, Jupiter's moon. Nonetheless, this place has been located at Borup Fjord Pass in the Canadian High Arctic....

Large quantities of globally produced plastics end up in the oceans where they represent a growing risk.  Above all very small objects, so-called microplastic particles, are endangering the lives of the many sea creatures. An estimate of how greatly the oceans are polluted with microplastic particles has so far failed in the absence of globally comparable methods of investigation and data. Together with British and Chilean colleagues, scientists of the Alfred Wegener Institute for Polar...

A deep-sea mystery has been solved with the discovery that the tiny 3 mm long marine animals, eaten by herring, cod and mackerel, use the same buoyancy control as whales. Reporting this week in the journal Limnology and Oceanography, researchers from British Antarctic Survey describe how Southern Ocean copepods "“ a crustacean rich in omega-3 oil "“ 'hibernates' in the deep ocean during winter when seas are stormy and food scarce. To reach the ocean depths the copepod's oily body...

But the lichen is so rare it may never be seen again A Philadelphia botanist who has studied rare plants for 50 years, but has never attained the honor of having a plant named for him is finally getting his due, but with a barely visible organism so rare it may never be seen again. Dr. Alfred "Ernie" Schuyler, emeritus curator of botany at the Academy of Natural Sciences and a world expert on rare plants, recently was honored when a colleague discovered a new species of lichen and named it...
