Why are some groups of animals so diverse?
A new study of finger-sized Australian lizards sheds light on one of the most striking yet largely unexplained patterns in nature: why is it that some groups of animals have evolved into hundreds, even thousands of species, while other groups include only a few? view more (2007-09-20)
Thieves promote stable coexistence among desert rodents
The warm deserts of North America are hopping with multiple species of kangaroo rats and pocket mice despite limited seed resources. view more (2006-07-27)
Symbiotic fungi promote invasion into diverse plant communities (Rudgers et al.)
The biodiversity of a community can affect its functional properties, such as its productiveness or its ability to resist invasion by exotic species. Many grass species host fungi in their leaves that can render them more resistant to herbivory, drought, and competition. In a forthcoming issue of Ecology Letters, Rudgers, Koslow and Clay... view more... (2003-12-10)
Study suggests past climate changes may have promoted the formation of new species in the Amazon
The results of a new study suggest that past climate changes and sea level fluctuations may have promoted the formation of new species in the Amazon region of South America. view more (2008-07-23)
Biodiversity conservation - no guarantee for shortcuts
New research from scientists at the University of Sheffield published in the November issue of Ecology Letters has cast doubts on the widely held `rule of thumb` that the conservation of a country`s biodiversity can be guaranteed by focusing on protecting its threatened and endemic species. In a report published this week, Aletta Bonn, Ana... view more... (2002-10-30)
New global bird map suggests 'hotspots' not a simple key to conservation
The first full map of where the world's birds live reveals their diversity 'hotspots' and will help to focus conservation efforts, according to research published in Nature today (18 August). view more (2005-08-18)
Study: Rain forest insects eat no more tree species than temperate counterparts
A study initiated by University of Minnesota plant biologist George Weiblen has confirmed what biologists since Darwin have suspected-that the vast number of tree species in rain forests accounts for the equally vast number of plant-eating species of insects. view more (2006-08-24)
Domestication of Capsicum annuum chile pepper provides insights into crop origin and evolution
Without the process of domestication, humans would still be hunters and gatherers, and modern civilization would look very different. view more (2009-06-22)
Different coat color may not mean different species for lemurs
Researchers have found that lemurs suspected to belong to different species because of their strikingly different coat colors, are not only genetically alike, but belong to the same species. view more (2006-11-16)
What makes life go at the tropics?
What causes tropical life to thrive: temperature, or sunlight? The answer is not necessarily "both." According to a study published online this week in PNAS Early Edition, the explosion of species at the tropics has much more to do with warmth than with light. view more (2008-05-28)
Darwin and the world's first ecological experiment
Scientists examining the work that influenced Charles Darwin have rediscovered the details of what may be the world's first ecological experiment. Darwin, in his Origin of Species of 1859, referred to an experiment investigating the biology of grassland plants that showed how a greater diversity of grasses planted in experimental plots was... view more...

More silent spring...?
The evocative sounds of some of the world's most remote places - rare birdsong and human languages - are both under threat. New research from the University of East Anglia compares these threats for the first time. view more (2003-05-14)
Exceptions prove rule of tropical importance in biodiversity
Even a group of shellfish that appear to violate the overarching pattern of global biodiversity actually follows the same biological rules as other marine organisms, confirming a general theory for the spread of life on Earth. view more (2007-11-08)
Scientists find new clues to explain Amazonian biodiversity
Ice age climate change and ancient flooding-but not barriers created by rivers-may have promoted the evolution of new insect species in the Amazon region of South America, a new study suggests. view more (2008-07-23)
A global model for the origin of species independent of geographical isolation
The tremendous diversity of life continues to puzzle scientists, long after the 200 years since Charles Darwin's birth. view more (2009-07-20)
Study: Bird diversity lessens human exposure to West Nile Virus
A study by biologists at Washington University in St. Louis shows that the more diverse a bird population is in an area, the less chance humans have of exposure to West Nile Virus (WNV). view more (2008-10-07)
Lemurs' fur color may not define species
Different coat colour might not correspond to different species for nocturnal lemurs. In a study published today in the open access journal BMC Evolutionary Biology, researchers find that lemurs that appeared to belong to different species because they have strikingly different coat colours, are in fact genetically related and belong to the same... view more...

Gray wolves feed the masses while hunters feed the few
Gray wolves (Canis lupus) and human hunters both provide resource subsidies to scavengers in Yellowstone National Park, USA, by provisioning them with the remains of their kills. Carrion from wolf versus hunter kills is much more dispersed in both time and space. In the November issue of Ecology Letters, scientists from Berkeley and Yellowstone... view more... (2003-10-08)
11,000 alien species invade Europe
For the first time it is now possible to get a comprehensive overview of which alien species are present in Europe, their impacts and consequences for the environment and society. view more (2008-11-21)
Imaging from space protects natural habitats
The method for remote designing of conserved natural territories has been developed by Russian researchers from the Severtsov Institute of Ecology and Evolution Problems, Russian Academy of Sciences, and the Faculty of Geography, Moscow State University, supported by WWF. The method was applied to the territories of the Far East, mountains of the... view more... (2003-11-06)
