Fire-scarred oaks reveal how Illinois changed under Native and settler Americans

Fire-scarred oaks reveal how Illinois changed under Native and settler Americans

Posted Wed, 16 Mar 2011 18:08:01 GMT by Martin Leggett

Fire was one of the main elements controlling the landscape around Illinois, according to a new paper in the journal Castanea. That landscape shifted from open wood and prairie to dense maple forest, as the use of 'controlled fires' changed. That is the story revealed in the multiple fire-scars found in 200 year old tree-rings of the state's once dominant post oaks.

Scientists have discovered two large species of stingray living in Amazonian basin in Peru, Ecuador and Brazil. The 80cm diameter, 25 kilo pancake-shaped beasts were found in the deeper channels of the river. Marcelo Rodrigues de Carvalho, ichthyologist at the University of Sao Paulo in Brazil was lead scientist and published his results in the journal Zootaxa.

The record of earthquakes past may be preserved in water-lain sediments, according to research from Tel Aviv University. These fossil-quakes leave tell-tale wave marks and help push back the record of seismic activity thousands of years. And the more information on an area's seismic past, the more confidently we can project future risks.

Death key to sex life of Satyrium pumilum orchid

Death key to sex life of Satyrium pumilum orchid

Posted Mon, 14 Mar 2011 14:29:00 GMT by Louise Murray

A South African orchid mimics the stench of corpses to draw in its pollinating carrion flies. The orchid, Satyrium pumilum targets a carrion feeding flesh fly as its pollinator and is so convincing that female flies have been seen laying eggs in the flower. In addition to its smelly perfume of decaying corpse, the interior of the flower is a mottled brown in colour that resembles rotting meat. Environmental issues: orchid/nature.

For the native birds of the Everglades, keeping an eye out for pythons is an increasing preoccupation. The burgeoning population of snakes, descended from pet-escapees, is seen as an increasing threat to some of the endangered species of Florida's National Park, says a study published in this month's BioOne.

A new report shows multiple threats to the world's bee colonies, leading to worries about global food security. Scientists are warning that we need to rethink the way in which humans manage the planet if we are to feed a growing world population. Bees and other pollinators are hugely important in global food production and integral to healthy ecosystems. Filed under environmental issues: ecosystems/nature.

Creatures that currently live in warm, shallow waters, can often survive in much harsher environments a team at Southampton University has found. A team at University of Southampton's School of Ocean and Earth Sciences (SOES) used the aptly-named variable shrimp to test there hypothesis that as deep sea creatures were killed off by climate change their places were taken by their neighbours in the shallow water.

New research indicates that volcanoes long thought to be dormant, can revive in a matter of months. It has traditionally been accepted that once a volcano's magma chamber had cooled down this was the sign that it had become dormant and that it was likely to remain so for many centuries. But research published in the latest edition of Nature casts doubt on this hypothesis. Filed under environmental issues: Volcanoes/Nature.

At 60 years old, Wisdom, a Laysan albatross, is the oldest wild bird known in the U.S. First recorded in 1956 as she incubated an egg, Wisdom has seen it all - from the first man on the moon, to the fall of the Berlin Wall and beyond.

Transforming corpses into compost is a much more eco-friendly process than traditional burial, or energy-hungry cremation. Environmentalists now have the option of a clean, green method for their last act of recycling. The promession process of organic burial involves first freezing the body to minus 18 degrees C, then freeze drying in liquid nitrogen at almost minus 200 degrees.

Elephants are commonly regarded as being intelligent but the sheer size of these majestic beasts has made proving that tough - until now. New research published in the Proceedings of the National Academy of the Sciences in America aims to prove that Elephants are clued-up enough to know how to work as a team.

Getting past media sensationalism to discover the real causes of mass animal death. Since last December when 83,000 Drum fish were washed up in Arkansas and thousands of blackbirds fell dead just 100km away in the town of Beebe, the world media has been full of reports of mass animal deaths. Journalists have gone as far as to nickname the phenomena 'aflockalypse'.

The invasion of the American north-west by the Tamarisk Tree and its natural enemy; the Tamarisk Leaf Beetle. The Tamarisk Leaf Beetle is inadvertently battling one of the greatest threats to the U.S. water reserves… by eating it. The Tamarisk Tree, which survives by absorbing river water in a sponge-like manner, has met its nemesis in the Tamarisk Leaf Beetle, an insect whose favourite food of choice is Tamarisk Tree leaf.

A reworking of satellite data is helping scientists track the Arctic spring and summer plankton blooms - that color the sea green as the ice retreats. Understanding how these evolve will help to paint the bigger picture of Arctic ecology as its sea-ice continues to disappear. Vast blooms of phytoplankton take advantage of the nutrient-rich sun-lit waters, starting off a cascade of life up the entire length of the Arctic food chain.
