Frontiers The open-access journal Frontiers in Ecology and Evolution reports the first known case where four species, all at different levels in the food chain, use a single odor to communicate with and ruthlessly exploit each other. Plant-feeding insects are often attracted to odors that are released by damaged plant tissue because these plants are already under attack and so a good place to look for food, sexual partners, and egg-laying sites. The jumping plant louse Diaphorina citri...

While sticking to a purely vegetarian menu, the food chain will serve new recipes and also offer discounts. (PRWEB) September 02, 2013 As the festive season is set to commence in India, the popular food chain Sai Bhoj has introduced new offerings, which are expected to attract customers. Starting from the month of September, 2013, all outlets of the company will be serving a range of new dishes that will make the traditional platter even more satiating. The dishes will be served on...

Metals contained in nanoparticles can enter into the food chain Scientists have, for the first time, traced the nanoparticles taken up from the soil by crop plants and analyzed the chemical states of their metallic elements. Zinc was shown to dissolve and accumulate throughout the plants, whereas the element cerium did not dissolve into plant tissue. The results contribute to the controversial debate on plant toxicity of nanoparticles and whether engineered nanoparticles can enter into the...

Prey Distribution, Not Biomass, Key To Marine Food Chain
2012-05-03 03:30:03

A new study has found that each step of the marine food chain is clearly controlled by the trophic level below it — and the driving factor influencing that relationship is not the abundance of prey, but how that prey is distributed. The importance of the spatial pattern of resources — sometimes called “patchiness” — is gaining new appreciation from ecologists, who are finding the overall abundance of food less important than its density and ease of access to...

Zooplankton Among First To Show Evidence Of Exposure To Deepwater Horizon Oil
2012-03-23 05:24:35

Ryan Parson for Redorbit.com Oil remnants from the Maconda-1 oil field have been discovered in animals in the northern Gulf of Mexico. Zooplankton samples collected from the Gulf of Mexico have shown positive evidence of exposure to oil that may have directly originated from the Deepwater Horizon oil spill. The effects of the deadly British Petroleum R/V Deepwater Horizon oilrig explosion that took place on April 20, 2010, will more than likely be present for many years to come....

Even In Winter, Life Persists In Arctic Seas
2012-02-23 04:59:29

Results of research cruise to Bering, Chukchi and Beaufort seas surprise scientists and may have implications for climate modeling Despite brutal cold and lingering darkness, life in the frigid waters off Alaska does not grind to a halt in the winter as scientists previously suspected. According to preliminary results from a National Science Foundation- (NSF) funded research cruise, microscopic creatures at the base of the Arctic food chain are not dormant as expected. After working...

Salmonella remains a serious cause of food poisoning in the UK and throughout the EU, in part due to its ability to thrive and quickly adapt to the different environments in which it can grow. New research involving a team of IFR scientists, funded by BBSRC, has taken the first detailed look at what Salmonella does when it enters a new environment, which could provide clues to finding new ways of reducing transmission through the food chain and preventing human illness. Bacteria can...

Peak concentrations of biocides from house paint prove prevalent in urban river basins Anti-fungal and anti-bacterial additives in house paint are present in dangerous quantities in the Vauchère river basin in the city of Lausanne, says a study to be presented the 9th of December, at the American Geophysical Union (AGU) conference in San Francisco. Chemicals engineered to kill microorganisms, called biocides, are added to exterior paints in order to prevent molding and plant...

A New Model For Understanding Biodiversity
2011-11-22 04:13:06

Researchers develop a unified theory of ecosystem change by combining spatial modeling and food web analysis Animals like foxes and raccoons are highly adaptable. They move around and eat everything from insects to eggs. They and other “generalist feeders” like them may also be crucial to sustaining biological diversity, according to a new study published this week in the Proceedings of the National Academy of Sciences (PNAS). McGill biology researchers have developed a...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
