A treasure trove of information about pre-human New Zealand has been found in faeces from giant extinct birds, buried beneath the floor of caves and rock shelters for thousands of years. view more (2009-01-12)
Antarctic icebergs: unlikely oases for ocean life
Icebergs have long gripped the popular imagination, whether as relatively run-of-the-mill floating hazards that cause "unsinkable' ships to founder or, more recently, as enormous breakaway pieces of ice the size of states or small countries. view more (2007-06-25)
Amazon rainforest at risk from initiative to connect South American economies
An unprecedented development plan to link South America's economies through new transportation, energy and telecommunications projects could destroy much of the Amazon rainforest in coming decades, according to a new study by Conservation International (CI) scientist Tim Killeen. view more (2007-10-02)
Iraq's marshes show progress toward recovery
Reflooding of Iraq's destroyed Mesopotamian marshes since 2003 has resulted in a "remarkable rate of reestablishment" of native invertebrates, plants, fish, and birds, according to an article in the June issue of BioScience. view more (2006-05-31)
Female Antarctic seals give cold shoulder to local males
Female Antarctic fur seals will travel across a colony to actively seek males which are genetically diverse and unrelated, rather than mate with local dominant males. view more (2007-02-08)
Madagascar : the forest in danger
Madagascar's forest is one of the most threatened in the tropical world. In the south-west of the island cultivation of maize on areas cleared by slash-and-burn methods is the main cause of deforestation which, particularly intense in this area, is increasing year by year. Research scientists from IRD (Institut de recherche pour le... view more... (2000-05-22)
Marine conservation organizations team up to conduct Indonesia coral reefs assessment
Three leading marine conservation organizations will complete an extensive survey next week along the west coast of Aceh Province, Indonesia, to determine the impact of last year's devastating earthquake and tsunami on the region's coral reefs. view more (2005-10-13)
Accelerating loss of ocean species threatens human well-being
An international group of ecologists and economists has shown that the loss of biodiversity is profoundly reducing the ocean's ability to produce seafood, resist diseases, filter pollutants and rebound from stresses such as overfishing and climate change. view more (2006-11-07)
Overfishing puts Southern California kelp forest ecosystems at risk, report scientists
Kelp forest ecosystems that span the West Coast -- from Alaska to Mexico's Baja Peninsula -- are at greater risk from overfishing than from the effects of run-off from fertilizers or sewage on the shore. view more (2006-05-26)
Parasites Outweigh Predators in Pacific Coast Estuaries
In a study of parasites living in three estuaries on the Pacific coast of California and Baja California, researchers have determined that biomass of these parasites exceeds that of top predators, in some cases by more than 20 times. view more (2008-07-24)
Modelling To Develop European Sand Dredging Guidelines
Computer predictions of the effects of commercial sea-sand dredging on coastal erosion, produced by an international team headed by Dr Alan Davies of the University of Wales, Bangor`s School of Ocean Sciences, will play a key role in developing new European Guidelines for siting commercial sand dredging activities. Increased demand for North Sea... view more... (2002-08-07)
Are wolves the pronghorn's best friend?
As western states debate removing the gray wolf from protection under the Endangered Species Act, a new study by the Wildlife Conservation Society cautions that doing so may result in an unintended decline in another species: the pronghorn, a uniquely North American animal that resembles an African antelope. view more (2008-03-04)
Colombian Frog Believed Extinct Found Alive
Researchers exploring a Colombian mountain range found surviving members of a species of Harlequin frog believed extinct due to a killer fungus wiping out amphibian populations in Central and South America. view more (2006-05-19)
Scientists report first remote, underwater detection of harmful algae, toxins
Scientists at NOAA's National Centers for Coastal Ocean Science and the Monterey Bay Aquarium Research Institute (MBARI) have successfully conducted the first remote detection of a harmful algal species and its toxin below the ocean's surface. view more (2009-07-15)
The petroleum umbrella
Several companies are extracting black gold - petroleum - from the North Sea. But scientists are questioning this activity and asking if this activity has environmental consequences. By law, these companies are obliged to carry out annual analyses. view more (2005-04-04)
Scientists Debate Wisdom of Plan to Save Venice From Flooding
WASHINGTON - The Italian government recently decided to move forward with planning for the construction of underwater, mobile floodgates to mitigate flooding in Venice, situated on islands in a lagoon in the Adriatic Sea. The soundness of the plan is discussed by several scientists in the May 14 issue of Eos, published by the American Geophysical... view more... (2002-05-08)
In the warming West, climate most significant factor in fanning wildfires' flames
The recent increase in area burned by wildfires in the Western United States is a product not of higher temperatures or longer fire seasons alone, but a complex relationship between climate and fuels that varies among different ecosystems. view more (2009-06-26)
Researchers to study rebirth of an island after volcanic eruption
When Alaska's Kasatochi Volcano erupted on Aug. 7, 2008, it virtually sterilized Kasatochi Island, covering the small Aleutian island with a layer of ash and other volcanic material several meters thick. view more (2009-08-07)
Biodiversity and resilience of coral reefs
With over 3000 fish species, Indo-Pacific coral reefs represent one of the most diverse ecosystems on the globe. It is easy to assume that the loss of one or two species from these systems would have little impact. However, in an article in the April issue of Ecology Letters, Bellwood and colleagues document major changes in Indo-Pacific coral... view more... (2003-04-08)
