Protecting Natural Spaces Does Not Prevent Invasion by Foreign Species
A study carried out by researchers at the Universitat Autònoma de Barcelonashows that protecting natural spaces does not prevent invasion by foreign vegetation species. Montserrat Vil'  and Jordi Pujadas, researchers at the CREAF, have published the study, the first to quantify the... view more (2002-02-27)

Direct link established between tropical tree and insect diversity
Higher tree species diversity leads directly to higher diversity of leaf-eating insects.   view more (2006-07-19)

Woody and aquatic plants pose greatest invasive threat to China
Although China currently has fewer invasive woody plants than the United States, China's potential for invasion by nonnative trees and shrubs is high, according to an article in the May 2008 issue of BioScience.   view more (2008-05-01)

What determines the speed at which birds fly?
Aerodynamic scaling rules that explain how flight varies according to weight and wing loading have been used to compare general speeds of a wide range of flyers, from the smallest insects to the largest aircraft.   view more (2007-07-17)

When fish become extinct, the cycling of critical nutrients in ecosystems changes, Cornell study finds
Ecosystems are such intricate webs of connections that few studies have been able to explore exactly what happens when a species dies out.   view more (2007-03-05)

Overfishing may drive endangered seabird to rely upon lower quality food
The effects of overfishing may have driven marbled murrelets, an endangered seabird found along the Pacific coast, to increasingly rely upon less nutritious food sources, according to a new study by biologists at the University of California, Berkeley.   view more (2005-12-20)

Biological invasions can begin with just 1 insect
A new study by York University biologists Amro Zayed and Laurence Packer has shown that a lone insect can initiate a biological invasion.   view more (2007-09-12)

Islands spark accelerated evolution
The notion of islands as natural test beds of evolution is nearly as old as the theory itself. The restricted scale, isolation, and sharp boundaries of islands create unique selective pressures, often to dramatic effect.   view more (2006-09-12)

Reliance on unverifiable observations hinders successful conservation of wildlife species
Nearly any evidence of the occurrence of a rare or elusive wildlife species has the tendency to generate a stir. Case in point: in February 2008, remote cameras unexpectedly captured the images of a wolverine in the central Sierra Nevada, an area from which the species was believed to be extinct... view more (2008-06-23)

Indigenous water frogs under threat
Indigenous water frogs can be crowded out by immigrant or imported species. This is the finding of a Franco-German study. The scientists investigated water frog populations in France and Northern Spain and noticed that the marsh frog (Rana ridibunda), which normally occurs only in Eastern Europe,... view more (2007-11-30)

Mixed dolphins and the impact of tourism
Dolphins off the coast of East Africa are exposed to a number of threats, like indirect catching, hunting, and environmental impact. In her dissertation at the Department of Zoology, Stockholm University, Sweden, Eva Stensland has studied behavioral ecology in Indo-Pacific bottlenose and humpback... view more (2004-05-07)

Do we need a paradigm change? Disputing coevolution in herbivorous insects
Coleoptera (beetles) are one of the most successful groups of organisms on Earth. Their success in evolutionary terms is recognised by their extreme adaptive diversity (occupying almost every possible ecological niche) and their longevity (fossils from the Palaeozoic, 280 million years ago).   view more (2007-04-11)

Poison dart frog mimics gain when birds learn to stay away
Studying neotropical poison dart frogs, biologists at the University of Texas at Austin uncovered a new way that the frog species can evolve to look similar, and it hinges on the way predators learn to avoid the toxic, brightly colored amphibians.   view more (2006-03-09)

Sensorial evaluation of the freshness of fish
AZTI has drawn up some 40 tables for freshness specific for the most important commercial species in southern Europe, including fish and shellfish. The sensorial method, known as QIM (Quality Index Method) and introduced into Europe some years ago, is being applied to a greater number of species,... view more (2005-04-18)

New dwarf buffalo discovered by chance in the Philippines
Almost 50 years ago, Michael Armas, a mining engineer from the central Philippines, discovered some fossils in a tunnel he was excavating while exploring for phosphate.   view more (2006-10-17)

Media invitation: How many species in Noah's Arc?
Scientists gather in Mallorca (Spain) to assess the role of biodiversity in ecosystem function. The remarkable increase, towards the end of 20th Century in the rate of species extinctions and the loss of biological diversities in the planet's ecosystems have generated considerable concern on the... view more (2004-05-11)

Sturgeon's general warning: Stable for now, but beware
They take a long time before they mate and, once old enough, don't mate every year. Even so, sturgeons are heavily sought after for their eggs, which are made into caviar.   view more (2006-08-24)

Satellite tracking reveals threats to Borneo pygmy elephants
A new WWF study tracking pygmy elephants by satellite shows that the remaining herds of these endangered elephants, which live only on the island of Borneo, are under threat from forest fragmentation and loss of habitat.   view more (2007-08-09)

3D birds on internet
The Zoological Museum of the Universiteit van Amsterdam (ZMA), Netherlands, is now presenting 3D images of part of the bird collection on the internet. This is a completely new technology and never before a part of the collection has been presented in this way. The database contains 151 images of... view more (2004-04-29)

Invasive plant outcompeted by its native ancestors
Invasive alien species are one of the greatest threats to global biodiversity. Part of their success may be due to rapid evolutionary changes when invaders adapt to the novel conditions in their invaded habitats. Invasive plants, in particular, are believed to double-profit from a loss of their... view more (2004-03-18)

World's rarest big cat gets a check-up
The world's rarest big cat is alive and well. At least one of them, that is, according to researchers from the Wildlife Conservation Society (WCS) who captured and released a female Far Eastern leopard in Russia last week.   view more (2008-10-31)

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)

Hearing is believing
Novel developments in electronics which are giving ecologists important new tools to quickly and easily measure biodiversity will be described at the British Ecological Society's Winter Meeting, being held at the University of York on 18-20 December 2002. Speaking at the meeting, electronics... view more (2002-12-09)

Attack of the invasive garden ants
An ant that is native to Eurasia is threatening to become the latest in a procession of species to invade Europe, as a result of inadvertent human introduction. Research published in the online open access journal BMC Biology demonstrates that the invasive garden ant, Lasius neglectus, which is a... view more (2008-02-26)

Cows as unravellers
Long-term conservation of biodiversity may depend not only on the maintenance of its component parts but also on their interactions. Human-aided species introductions stand out as a major anthropogenic modification of ecological systems, and there is increasing concern that such introductions can... view more (2003-11-24)
