Some animals won't adapt to climate change
In a fascinating study appearing in the November issue of The American Naturalist, biologists investigated the response of small animals to climate change on a remote sub-Antarctic Island. view more (2006-11-14)
Scientists say climate change mitigation strategies ignore carbon cycling processes of inland waters
In the paper, The Boundless Carbon Cycle, published in the September issue of Nature Geoscience, scientists from the University of Vienna, Uppsala University in Sweden, University of Antwerp, and the U.S. based Stroud™ Water Research Center argue that current international strategies to mitigate manmade carbon emissions and address climate... view more...

New report says human tampering threatens planet's life-sustaining surface
In a report released today, scientists call for a new systematic study of the Earth's "critical zone"-the life-sustaining outermost surface of the planet, from the vegetation canopy to groundwater and everything in between.Understanding and predicting responses to global and regional change is necessary, they say, to mitigate the impacts... view more...

New protocol tracks how land use influences the way streams work
Virginia Tech biology researchers have applied tools from geology, geography, and hydrologic modeling to determine the effect of different land uses on stream quality across 10 watersheds of the French Broad River in the North Carolina mountains. view more (2005-10-13)
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)
Bio-archaeologists pinpoint oldest Northern European human activity
Scientists at the University of York used a 'protein time capsule' to confirm the earliest record of human activity in Northern Europe. view more (2005-12-15)
Where Does the North Pole Ice Come From? The Origin of the Northern Hemisphere Ice Age
Large areas of the Northern Hemisphere are currently covered with ice. This has, however, not always been the case. In the current issue of the science magazine "Nature", scientists from the GeoForschungsZentrum Potsdam (GFZ) and the Potsdam Institute for Climate Impact Research (PIK) present a possible solution for the oldest mystery of palaeo... view more...

Morphology of fossil salamanders reflects climate change
A fossil record of the Tiger Salamander (Ambystoma tigrinum) shows population-wide changes in body size and morphology in response to climate change over the last 3,000 years. view more (2005-09-13)
A salinity study in the Mobile Delta region
Habitat modifications are among mankind's most pervasive alterations of our nation's estuarine ecosystems. When such modifications are extensive, as is the case for the Mobile Bay Causeway, they can alter patterns of natural hydrography. view more (2006-10-16)
Snowy owl -- a marine species?
Wildlife satellite studies could lead to a radical re-thinking about how the snowy owl fits into the Northern ecosystem. view more (2008-12-11)
Cosmic dust in terrestrial ice
For the last 30,000 years, our planet has been hit by a constant rain of cosmic dust particles. view more (2006-07-28)
Getting By With A Little Help From Your Friends
University of Ulster research probes pals' influences on Northern Ireland prejudice levels. Just having a friend who has a friend from the 'other side' can reduce levels of sectarian prejudice among individuals in Northern Ireland, according to new psychological research from the University of Ulster. This research was carried out in the context... view more... (2004-06-16)
University of Ulster Announces £12m+ Venture Capital
The University of Ulster is to launch a £12m+ Venture Capital Fund to help commercialise the products of its research programmes. view more (2002-04-30)
Land won't soak up carbon indefinitely say top scientists
A paper to be published this week in the journal Nature provides a new global view of terrestrial carbon sources and sinks and warns that current sinks cannot be counted on to mop up carbon dioxide emissions indefinitely. The results have potential implications for the Kyoto Protocol negotiations where recent difficulties have included a lack of... view more... (2001-11-06)
Ancient British bog provides clue to global warming
Analysis of sediments from a British bog suggest that methane emissions increased due to intense global warming around 55 million years ago. view more (2007-09-20)
The emerging scientific discipline of aeroecology
In the history of science and technology, there is an infrequent combination of empirical discoveries, theories and technology developments converge that make it possible to recognize a new discipline. view more (2008-08-04)
Ecosystems with many plant species produce more and survive threats better
Ecosystems containing many different plant species are not only more productive, they are better able to withstand and recover from climate extremes, pests and disease over long periods, according to a new study. view more (2006-06-01)
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 southern aurora. A volcanic eruption was also imaged... view more... (2001-06-07)
Natural-born divers and the molecular traces of evolution
An aquatic lifestyle imposes serious demands for the organism, and this is true even for the tiniest molecules that form our body. view more (2009-06-29)
Seagrass ecosystems at a 'global crisis'
An international team of scientists is calling for a targeted global conservation effort to preserve seagrasses and their ecological services for the world's coastal ecosystems, according to an article published in the December issue of Bioscience, the journal of the American Institute of Biological Sciences (AIBS). view more (2006-12-01)
