Major initiative proposed to address amphibian crisis
Fifty of the leading amphibian researchers in the world have called for a new Amphibian Survival Alliance, a $400 million initiative to help reduce and prevent amphibian declines and extinctions, an ecological crisis of growing proportion that is continuing to get worse.   view more (2006-07-07)

Protecting fish nurseries
A University of Plymouth lecturer and his PhD student are putting Plymouth on the world map for research in a specialist field of marine biology: the importance of seagrass meadows. Seagrass can grow prolifically in outer estuarine areas and is the only flowering plant fully adapted for life in... view more (2002-03-21)

Mean Population Size Increases with Diversity
A long-standing debate in ecology has been the effect of diversity on the temporal stability of biological systems. Ecological theory predicts that the stability of populations should decline as community diversity increases, in part, because population size is assumed to decline with community... view more (2003-01-28)

Insect warning colors aid cancer and tropical disease drug discovery
Brightly colored beetles or butterfly larvae nibbling on a plant may signal the presence of chemical compounds active against cancer cell lines and tropical parasitic diseases, according to researchers at Smithsonian's Tropical Research Institute in Panama.   view more (2008-07-09)

Geologist urges seismic shift in process for selecting EarthScope study sites
EarthScope, an enormous, nationwide earth science project, is poised to revolutionize understanding of earthquakes, fault systems, volcanoes and the North American continent's structure.   view more (2005-10-17)

Aurorae and Volcanic Eruptions
Impressive thermal-infrared images have been obtained of the giant planet Jupiter during tests of a new detector in the ISAAC instrument on the ESO Very Large Telescope (VLT) at the Paranal Observatory (Chile). They show in particular the full extent of the northern auroral ring and part of the... view more (2001-06-07)

Ants are surprisingly ancient, arising 140-168 million years ago
Ants are considerably older than previously believed, having originated 140 to 168 million years ago, according to new Harvard University research published in the journal Science.   view more (2006-04-12)

Everyone wants gamma-ray eyes!
Even before ESA`s Integral gamma-ray observatory was launched, astronomers were competing to win time to use this state-of-the-art observatory. The Integral Science Operations Centre in Noordwijk, The Netherlands, received hundreds of excellent proposals. ESA expects Integral to revolutionise the... view more (2002-10-29)

Scientific design of GM farm-scale evaluations made public
The 40th anniversary issue of the British Ecology Society's Journal of Applied Ecology this month leads with two major papers describing the background, methodology and experimental design of the farm-scale evaluations of genetically modified herbicide-tolerant crops. In laying out the statistical... view more (2003-02-07)

Astronomers find new evidence for the violent demise of sun-like stars
Two astronomers have used NASA's Chandra X-ray Observatory to discover a shell of superheated gas around a dying star in the Milky Way galaxy.   view more (2005-05-31)

Seed dispersal in mauritius -- dead as a dodo?
Walking through the last rainforests on the volcanic island of Mauritius, located some 800 km east of Madagascar, one is surrounded by ghosts.   view more (2008-05-07)

A link between greenhouse gases and the evolution of C4 grasses
How a changing climate can affect ecosystems is an important and timely question, especially considering the recent global rise in greenhouse gases.   view more (2007-12-21)

New Instruments To Picture The Early Universe
The latest instrument of the UK's Tenerife Cosmic Microwave Background Experiment, has been officially inaugurated at the mountain top Teide Observatory of the Instituto de Astrofisica de Canarias, IAC, on Tenerife. The ceremony coincided with the announcement by the PPARC of major support for a... view more (1996-07-03)

Powerful Nearby Supernova Caught By Web
One of the nearest supernovas in the last 25 years has been identified over a decade after it exploded. This result was made possible by combining data from the vast online archives from many of the world's premier telescopes.   view more (2008-09-26)

e-Science, fundamental physics and the GRID
Research into e-Science reached a milestone in the UK today [Thursday 25 April] when Gordon Brown, The Chancellor of the Exchequer, opened The National e-Science Centre in Scotland. The centre, run jointly by the Universities of Glasgow and Edinburgh, will provide a focal point for the UK`s... view more (2002-04-25)

Ice age imprint found on cod DNA
An international team of researchers, led by the University of Sheffield, has demonstrated how Atlantic cod responded to past natural climate extremes. The new research could help in determining cods vulnerability to future global warming.   view more (2007-11-14)

Climate change creates dramatic decline in red-winged black bird population
Global warming strikes again. A University of Illinois researcher reports that a red-winged black bird population in Ontario, Canada has decreased by 50 percent since 1972.   view more (2006-11-14)

Marine pathogens spread much faster than their terrestrial counterparts
It has become increasingly clear that pathogen epidemics are as significant a component of marine systems as they are in terrestrial systems. At an National Center for Ecological Analysis and Synthesis (NCEAS) working group on Diseases in the Ocean, McCallum, Harvell and Dobson collated data on... view more (2003-11-24)

NASA finds direct proof of dark matter
Dark matter and normal matter have been wrenched apart by the tremendous collision of two large clusters of galaxies. The discovery, using NASA's Chandra X-ray Observatory and other telescopes, gives direct evidence for the existence of dark matter.   view more (2006-08-22)

Cosmic Lens Reveals Distant Galactic Violence
By cleverly unraveling the workings of a natural cosmic lens, astronomers have gained a rare glimpse of the violent assembly of a young galaxy in the early Universe. Their new picture suggests that the galaxy has collided with another, feeding a supermassive black hole and triggering a tremendous... view more (2008-10-21)

Another bar in the Bulge
Using 2MASS data, Christophe Alard (astronomer at Paris Observatory) has reconstructed a map of the projected density of the old stellar population of the Galactic Bulge region. By making a combination of the H and K photometric bands, it is possible to overcome the effect of reddening, and thus... view more (2001-11-21)

Biodiversity loss linked to economic inequality worldwide
An interdisciplinary team of McGill researchers has uncovered a connection between growing economic inequality and an increase in the number of plant and animal species that are threatened with extinction.   view more (2007-05-16)

Some biofuels might do more harm than good to the environment, study finds
Biofuels based on ethanol, vegetable oil and other renewable sources are increasingly popular with government and environmentalists as a way to reduce fossil fuel dependence and limit greenhouse gas emissions.   view more (2008-05-28)

New modeling study forecasts disappearance of existing climate zones
A new climate modeling study forecasts the complete disappearance of several existing climates in tropical highlands and regions near the poles, while large swaths of the tropics and subtropics may develop new climates unlike any seen today.   view more (2007-03-28)

Predators: an overlooked player in plant-pollinator relationships
Biologists have long recognized that predators can help to shape ecological communities -- wolves promote the growth of young trees through predation on moose, otters keep kelp forests thriving by preying on sea urchins, etc. Yet we have seldom considered the consequences of predation on animals... view more (2003-08-13)
