Flowers rely on advertising
Some unusual graffiti shows how important the advertising signs are among the wild flowers. Six white stripes on a dark Iris flower, a kind of a wild point of vital "proboscis here insert" opening at the saczy nectar. Erasing ink to some or all of these characters, the Guide did not make much difference in whether pollinators approached flower. However, a few pollinators of flowers defaced sipped and pollen spread dropped as low as zero, Dennis Hansen and colleagues report on the University of KwaZulu-Natal, South Africa in the coming of the Royal Society b. — Susan Milius
Hope for the return of the cod
New data crunching four decades suggests that predatory fish such as cod finally may be able to increase their numbers. Far exceeded the Canadian East Coast Scotian Shelf has not returned despite the beginning of the closure of the fishery virtual in the early 1990s. For 15 years the numbers of cod and other species of predatory fish remain low during eating plankton and fish of larger invertebrates boomed. Now the plankton eaters seems to have outpaced food supply and reducing their predation as cod opportunity offers, Kenneth Bedford Institute of Oceanography, Frank in Nova Scotia and his colleagues argue online 27 July in nature. — Susan Milius
Fruit loo
One of the toilets of nature uses fruity smell to its furry critters to lure dangerous rims. Carnivorous pitcher plants of Borneo Nepenthes rajah is a favorite tree shrews and the throne for rats. While the Association of the Leading pool animals lick the lid at the plant and provide rich nutrient now poopy. And they occasionally drown in bowl, which is filled with digestive juices soupy, insects and fecal matter. Now, scientists from Germany and Malaysia think they know, which maintains a small mammals return to toilets: lid exudes hydrocarbons, esters, ketones and alcohols — compounds that produce tempting fruity or wonderful, the team reports in the journal of Tropical Ecology of July.

Deciduous beckon Bats transmitters
Although they are not as flashy as their neighbors kwiatowym, Plain old leaf could attract too pollinators. Bat Echolocation signals bounce off the leaves growing on bat pollinated Cuban rainforest Marcgravia vines, the evenia scientists from Germany and the U.K. Report 29 July in science. Strange, the dish-shaped leaf hangs above the vine ring of flowers. Shooting simulated animal echolocation calls of leaves produced a strong, multifaceted and invariant reflection. Deleting a leaf feeding Time doubled Nectar nectar bats, suggesting that in fact, ECHO is a significant pull nocturnal pollinators. Strange leaf shape and orientation affects the efficiency of the photosynthetic, but scientists think that the cost is offset by the benefits has registered the pollination of bat. Nadia – Drake
