Smithsonian's National Zoo researchers use electronic eggs to help save threatened species
This is an important summer for kori bustards at the Smithsonian's National Zoo. Four chicks of this threatened African bird have hatched in June and July. view more (2007-07-27)
Migratory flux and new racism
The growing migratory flux to Portugal makes it necessary to re-examine the fundamental question of social co-existence among groups that are culturally different. Recent research in social psychology carried out at Instituto de Ci'™ncias Sociais da Universidade de Lisboa - ICSUL (Social Sciences Institute of Lisbon University), within the... view more...

Dramatic shift from simple to complex marine ecosystems occurred 250M years ago at mass extinction
The earth experienced its biggest mass extinction about 250 million years ago, an event that wiped out an estimated 95% of marine species and 70% of land species. New research shows that this mass extinction did more than eliminate species: it fundamentally changed the basic ecology of the world's oceans. view more (2006-11-27)
Yale study offers new paradigm on ecosystem ecology
Predators have considerably more influence than plants over how an ecosystem functions, according to a Yale study published today in Science. view more (2008-02-15)
Scientists behind 'doomsday seed vault' ready the world's crops for climate change
As climate change is credited as one of the main drivers behind soaring food prices, the Global Crop Diversity Trust is undertaking a major effort to search crop collections-from Azerbaijan to Nigeria-for the traits that could arm agriculture against the impact of future changes. view more (2008-09-18)
Reforestation using exotic plants can disturb the fertility of tropical soils
In many regions of the world, the impact of human activity on the environment intensified considerably over the past century. The high world population growth rate and the expansion of areas given over to crop production associated with climatic changes (longer periods of drought, irregular rainfall patterns) induced by global warming, have... view more...

Birds and plants do not prosper under agri-environment schemes
Lapwing, Oystercatcher, Redshank and Godwit prefer common grasslands. The agri-environmental schemes to improve biodiversity in Dutch agricultural landscapes are not effective. A profound study which compares fields with management agreements with common managed fields, finds no positive effects on plant and bird species diversity. Meadow birds... view more... (2001-10-15)
Insect predation sheds light on food web recovery after the dinosaur extinction
The recovery of biodiversity after the end-Cretaceous mass extinction was much more chaotic than previously thought, according to paleontologists. view more (2006-08-25)
Iowa State researcher studies gene families to explore diversity and evolution
Theoretical biologist Stephen Proulx studies gene families to explore how genomes become diverse and evolve. view more (2006-08-01)
Yale undergrads' Amazon trip yields a treasure trove of diversity
A group of Yale undergraduates have discovered dozens of potentially beneficial bioactive microorganisms within plants they collected in the Amazon rain forest, including several so genetically distinct that they may be the first members of new taxonomical genera. view more (2008-08-25)
Biologists Produce Global Map of Plant Biodiversity
Biologists at the University of California, San Diego and the University of Bonn in Germany have produced a global map of estimated plant species richness. Covering several hundred thousand species, the scientists say their global map is the most extensive map of the distribution of biodiversity on Earth to date. view more (2007-03-21)
Conserving historic apple trees
The apple trees of yesteryear are slowly disappearing. Many apple varieties common in the United States a century ago can no longer be found in today's orchards and nurseries. view more (2009-11-05)
Brown Scientists Say Biodiversity Is Crucial to Ecosystem Productivity
In the first experiment involving a natural environment, scientists at Brown University have shown that richer plant diversity significantly enhances an ecosystem's productivity. view more (2008-04-25)
Ecology Drives The Worldwide Distribution Of Human Diseases
Mounting evidence suggests that ecological and climatic conditions influence the emergence, spread, and recurrence of infectious diseases. Global climate change is likely to aggravate climate-sensitive diseases in unpredictable ways. Increasingly, public health programs aimed at preventing and controlling disease outbreaks are considering aspects... view more... (2004-06-09)
Climate caused biodiversity booms and busts in ancient plants and mammals
A period of global warming from 53 million to 47 million years ago strongly influenced plants and animals, spurring a biodiversity boom in western North America, researchers from three research museums report in a paper published online this week in the Proceedings of the National Academy of Sciences. view more (2009-08-07)
Nature surrenders flowery secrets to international team
The poet Dylan Thomas wrote, "The force that drives the green fuse drives the flower." Now, a team of international scientists has unlocked some of the secrets of that force: it has described the rules that govern how plants arrange flowers into branching structures, known in technical terms as 'inflorescences.' view more (2007-05-25)
Scientists demonstrate importance of niche differences in biodiversity
Scientists at UC Santa Barbara have found strong evidence that niche differences are critical to biodiversity. Their findings are published online in this week's issue of the journal Nature. view more (2009-08-13)
First Biodiversity Census of coral reef ecosystems in the NW Hawaiian Islands
As part of the international Census of Marine Life (CoML), a team of world renown scientists will embark on an expedition to explore coral reef biodiversity in the largest fully protected marine area in the world-the Northwestern Hawaiian Islands Marine National Monument. view more (2006-10-11)
New CU-Boulder study shows diversity decreases chances of parasitic disease
A new University of Colorado at Boulder study showing that American toads who pal around with gray tree frogs reduce their chances of parasitic infections known to cause limb malformations has strong implications for the benefits of biodiversity on emerging wildlife diseases. view more (2008-10-22)
Fossil Patagonian plants show high insect feeding diversity 52 million years ago
South America has the most biodiversity of any major region today and according to an international team of researchers, that biodiversity began at least 52 million years ago. view more (2005-06-16)
