Reciprocal signaling in honeyguide-human mutualism 22.07.2016

Reciprocal signaling in honeyguide-human mutualism Abstract Greater honeyguides ( Indicator indicator ) lead human honey-hunters to wild bees’ nests, in a rare example of a mutualistic foraging partnership between humans and free-living wild animals. We show experimentally that a specialized vocal sound made by Mozambican honey-hunters seeking bees’ nests elicits elevated cooperative behavior from honeyguides. The production of this sound increased the probability of being guided by a honeyguide from about 33 to 66% and the overall probability of thus finding a bees’ nest from 17 to 54%, as compared with other animal or human sounds of similar amplitude. These results provide experimental evidence that a wild animal in a natural setting...

Happiness of ornithologist ... 28.05.2016

Of course there is happiness, this is unlikely anyone will argue. But for different people it is quite different, although in recent years more and more associated with material goods. For people engaged in science, the material is usually relegated to the background, although it is important. But in any case the first place is the opening of the desire and luck is not all! May 22 of this year, all the news spread through the ornithological resources of good news in Brazil found the bird, extinct in the number of lists. Since 1941, about it at all was not any news. However, and until 1941, only 8 reliable findings: 5 in the 19th century and 3 - in the twentieth. And then out of the blue just 12 ... at least! And live! This one's gone! Blue-eyed...

IN THE RED SEA DISCOVERED A NEW SPECIES OF THE LUMINOUS POLYPS 19.02.2016

IN THE RED SEA DISCOVERED A NEW SPECIES OF THE LUMINOUS POLYPS Author: Antonenko Andrei – from internet editions of "World of Wildlife", 2016   An international team of biologists, which included scientists from the M. V. Lomonosov Moscow State University, opened the Red Sea, on the reef Farasan Archipelago (Saudi Arabia), a new species fluorescent polyps living in the shells of shellfish, and collected his DNA samples. Article about it, published in the journal PLoS One , tells the press release of the Moscow University. Opened animals are miniature hydroid polyps, or hydroids (being reminiscent of the hydras a school textbook, which fall to them relatively close relatives) with a body length of about 1.5 millimeters. They live in...
