Invasions from 'above' worse than those from 'below'

Invasions from 'above' worse than those from 'below'

Posted Wed, 28 Sep 2011 06:08:00 GMT by Dale Kiefer

New research shows that invasive species introduced 'upstream' spread more rapidly and colonize more successfully than species that are introduced downrange within a given habitat.

The Beetles Hit (on Amphibian prey)

The Beetles Hit (on Amphibian prey)

Israeli beetles turning the tables on five spp. of Amphibian. The classic instance of predators stalking their live and not-so-innocent food supply is reversed with the prey waiting to be stalked by the naive predator. They then turn the tables by killing the villain - but just where would the observers' sympathies lie?

New research shows for the first time that penguins use scent to tell one another apart and avoid interbreeding. Scientists at the University of Chicago and the Chicago Zoological Society report that penguins use a highly-developed sense of smell to identify their kin, thus avoiding interbreeding with relatives.

Oldest North American Beaver Remains Found in the Beaver State

Paleontologists working in northern Oregon's Rattlesnake Formation have identified fossilized beaver teeth believed to be about 7 million years old, which is at least 2 million years older than any previously discovered beaver remains. The finding sheds new light on our understanding of when modern beavers first came to North America and diverged from the Eurasian beaver.

Why slow-and-steady jellyfish beat fish in oceanic contest

Why slow-and-steady jellyfish beat fish in oceanic contest

Posted Thu, 15 Sep 2011 18:00:01 GMT by Martin Leggett

A new paper in Science has gone a long way to clearing-up why primitive jelly-fish are often able to out-compete hard-pressed fish. The inclusion of their low-energy use into the modeling equations used by ecologists, shows that jellyfish and fish are on more of an equal footing than previously believed - and so jellyfish may carry on winning-out whilst over-fishing continues.

Observant scientists have discovered a rare example of animal hybrid speciation, in the forests of the Appalachian Mountains in the eastern United States. The creature in question, the Appalachian tiger swallowtail butterfly (Papilio appalachiensis), is the genetically unique result of the union of two related butterflies.

Fruit bats have the ability to vary the scope of their sonar probings, to match up with the complexity of the feeding ground they are flying through, according to scientists. This flexible adaptation of the senses could be a first, say the research team, who are publishing their paper on the PLoS ONE website today.

A United Nations top scientist believes that coral reefs will potentially be the first ecosystem that human activity effectively destroys. A new book released this week in the United States, Professor Peter Sale, who leads the United Nations University Institute for Water, Environment and Health, states his concern that the world's coral reef ecosystems are likely to disappear this century.

Earthquakes launched half of the Belizean Barrier Reef into deeper waters. Studying the possible effects of natural disasters must play a role in protecting ecosystems, researchers assert. The Belizean Barrier Reef is the second largest reef ecosystem in the world, second only to Australia's Great Barrier Reef.

Another important body in the Chinese medicinal community has come out strongly against the use of rhino horn in traditional remedies. The Register of Chinese Herbal Medicine has put out a statement condemning the practice, which may go a long way to shifting attitudes, and reducing demand for the horns of these endangered animals.

Intriguing research published in Science today has uncovered the details of the fluttering sound-scaping used by male hummingbirds, as part of the dramatic diving displays, given to impress watching females. The tones produced by feather-fanning are more complex than first thought, and are distinct for each humming bird species, say the researchers.

Latest storm off US coast gathers pace. Hurricane Katia, currently around 450 miles south of Bermuda is now capable of reaching winds up to 135 mph according to the National Hurricane Center. The storm has moved over warmer water, allowing it to pick up speed. However analysts believe that Hurricane Katia is unlikely to hit land over the coming days in the US.
