The definition of conservation priorities for biodiversity often focuses only on the numbers of vertebrate animals and seed plants in the northern hemisphere or in the tropics. view more (2007-10-25)
Global warming threatens tropical species, the ecosystem and its by-products
Tropical lizards detect the effects of global warming in a climate where the smallest change makes a big difference, according to herpetologist Laurie Vitt, curator of reptiles and George Lynn Cross Research Professor at the University of Oklahoma's Sam Noble Museum of Natural History view more (2009-08-26)
New fossil plant discovery links Patagonia to New Guinea in a warmer past
Fossil plants are windows to the past, providing us with clues as to what our planet looked like millions of years ago. view more (2009-11-11)
New species of ghostshark from California and Baja California
New species are not just discovered in exotic locales-even places as urban as California still yield discoveries of new plants and animals. view more (2009-09-22)
Challenges of HIV-1 subtype diversity
A review article in the New England Journal of Medicine explores the genetic variation of HIV-1 and its implications for preventing and treating the disease. Francine McCutchan, Ph.D., a researcher with the U.S. Military HIV Research Program, co-authored the article, which appeared in the April 10, 2008 edition. view more (2008-05-22)
Smithsonian coral biodiversity survey of Panama's Pearl Islands
A comprehensive survey of coral biodiversity in Panama's Las Perlas Archipelago, published in the journal Environmental Conservation by researchers from the Smithsonian Tropical Research Institute and their colleagues, has resulted in clear conservation recommendations for a new coastal management plan. view more (2008-07-08)
The Fancier the Cortex, the Smarter the Brain?
Why are some people smarter than others? In a new article in Current Directions in Psychological Science, a journal of the Association for Psychological Science, Eduardo Mercado III from the University at Buffalo, The State University of New York, describes how certain aspects of brain structure and function help determine how easily we learn new... view more...

First worldwide search for all microbes of the oceans starts now
The single-celled organisms of the world's oceans are immensely diverse. For the 'International Census of Marine Microbes' scientists are going to track down knowledge on the diversity and distribution of these micro-organisms and their viruses. The budget? 900,000 dollars of the Sloan Foundation in New York to start with. On February 7 and 8, the... view more... (2005-02-03)
The origin of HIV-1 New clarification from an epidemiological study in central Africa
An enormous variety of strains of HIV-1 are circulating in the Democratic Republic of Congo (DRC, ex-Zaire). The diversity is much higher than that observed in other African countries and as great as that encountered in the world as a whole. This is the main finding of a wide-ranging epidemiological study undertaken by an IRD research unit (UR 036... view more... (2001-04-25)
Round Goby invade Great Lakes
Canadian scientists uncover alarming invasion of round goby into Great Lakes tributaries: impact on endangered fishes likely to be serious. view more (2009-08-12)
Human activity destroys species that the Ice Age could not
Forest clearance and animal overgrazing in the last 5,000 years have destroyed important tree species that had survived even the Ice Age. Dr Mick Frogley, Lecturer in Physical Geography at the University of Sussex, is one of a British research team exploring a site near Lake Ioannina in the Pindus Mountains of northwestern Greece. "Given the... view more... (2002-09-20)
Scorpion biodiversity
Scorpions possess resistance to high temperatures and the ability to conserve water for long periods of time, and as a result thrive in hot and arid parts of the world. view more (2009-04-10)
Extinction
Two teams of British scientists have produced the best evidence yet that our planet is experiencing a mass extinction. Two separate papers, published in Science 19 March and funded largely by the Natural Environment Research Council (NERC) highlight the serious concerns that have been growing among the world's scientists for over ten years. John... view more... (2004-03-18)
Helping the aged gut replace good bacteria may reduce cancer risk
Eating certain foods can increase the number of protective microbes in the gut. These bacteria help prevent food poisoning and can reduce levels of some toxic chemicals that may cause cancer, scientists heard today (Wednesday 10 April 2002) at the spring meeting of the Society for General Microbiology at the University of Warwick. "We have... view more... (2002-04-02)
Conservation in Canada
Conservation actions could be more efficient if there is similarity among taxa in the distribution of species. In a paper in Ecology Letters, May, by an international research team, patterns in the geographic distribution of five taxa were used to identify nationally important regions for conservation in Canada. There was congruence in both... view more... (2004-05-04)
Amphibians as environmental omen disputed
Amphibians, for years considered a leading indicator of environmental degradation, are not uniquely susceptible to pollution, according to a meta-analysis to be published in Ecology Letters. view more (2009-11-12)
New host species for avian influenza identified
In a new study published online in the open-access journal PLoS Pathogens, Dr. Vincent J. Munster, of Erasmus Medical Center, Rotterdam, and colleagues identify new host species for avian influenza A virus (H5N1) and provide important information on the distinctions between the ecology and epidemiology of various global strains of the virus. view more (2007-05-11)
Good times ahead for dinosaur hunters, according to U of Penn scientist's dinosaur census
The golden age of dinosaur discovery is yet upon us, according to Peter Dodson at the University of Pennsylvania. view more (2006-09-05)
Database shows effects of acid rain on microorganisms in Adirondack Lakes
Prior to the federal Clean Air Act, unhindered industrial emissions were released into the air throughout the Midwestern and Eastern United States for decades. Many of those harmful chemicals came right back down to earth in the form of acid rain, a chemical concoction that includes nitric and sulfuric acid. view more (2008-06-24)
Moths cloaked in color
Travelers to the neotropics-the tropical lands of the Americas-might be forgiven for thinking that all of the colorful insects flittering over sunny puddles or among dense forest understory are butterflies. view more (2009-08-31)
