Species detectives track unseen evolution
New species are evading detection using a foolproof disguise - their own unchanged appearance. Research published in the online open access journal, BMC Evolutionary Biology, suggests that the phenomenon of different animal species not being visually distinct despite other significant genetic... view more (2007-07-19)

Predicting the species diversity of large herbivores in nature reserves
The number of species of large herbivores that can live in a nature reserve can be easily calculated using just rainfall and soil fertility data. The Wageningen ecologist Dr Han Olff can use this to indicate on a worldwide basis where nature reserves that protect large mammals are needed. On a map... view more (2002-02-19)

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... view more (2002-09-20)

Climate change could trigger 'boom and bust' population cycles leading to extinction
Climate change could trigger "boom and bust" population cycles that make animal species more vulnerable to extinction. , according to Christopher C. Wilmers, an assistant professor of environmental studies at the University of California, Santa Cruz.   view more (2007-04-17)

Competition between species curbs selfishness?
Animals are in constant competition over procreative resources. The interests of the individual and the population are not necessarily one and the same; aggressive insects may fare well in the mating competition, but eventually the proliferation of aggressive genes will weaken the procreative... view more (2004-12-20)

UT researcher sheds new light on hybrid animals
What began more than 50 years ago as a way to improve fishing bait in California has led a University of Tennessee researcher to a significant finding about how animal species interact and that raises important questions about conservation.   view more (2007-09-18)

Introduced marine species get larger in the invaded region
The transport of species outside their native region through human activities has often had a dramatic impact on the ecosystems into which these species are introduced and on the surrounding economies. The consequences of introduction for the introduced species itself, including changes in body... view more (2003-08-13)

Thriving Hybrid Salamanders Contradict Common Wisdom
A new UC Davis study not only has important findings for the future of California tiger salamanders, but also contradicts prevailing scientific thought about what happens when animal species interbreed.   view more (2007-09-27)

All species are not created equal when assessing the impacts of species loss on ecosystems
Numerous studies have shown that when species are randomly lost from communities, ecosystem function declines. But such patterns of species loss do not reflect those in natural communities where major drivers of change, such as stress and disturbance, cause preferential loss of rare and uncommon... view more (2003-05-22)

Avian influenza: the threat looms (p 257)
The potential threat of avian influenza is discussed in this week's editorial. Five human deaths have been reported in Vietnam up to Jan 20, 2004. The disease is caused by influenza virus type A, and infects many animal species. A highly pathogenic avian influenza is caused by subtypes H5 and H7;... view more (2004-01-21)

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)

Brown-led study rearranges some branches on animal tree of life
A study led by Brown University biologist Casey Dunn uses new genomics tools to answer old questions about animal evolution. The study is the most comprehensive animal phylogenomic research project to date, involving 40 million base pairs of new DNA data taken from 29 animal species.   view more (2008-03-06)

Evolution reveals an independent route for diversity in animal form
Researchers have found that Cnidaria, a group of marine animals noted for diverse morphology among its constituent species, actually lacks the ancient "Hox" gene system that is essential for the development of most other animals.   view more (2006-05-05)

Hebrew University researchers uncover eight previously unknown species
Discovery of eight previously unknown, ancient animal species within "a new and unique underground ecosystem" in Israel was revealed today by Hebrew University of Jerusalem researchers.   view more (2006-05-31)

Rove beetles act as warning signs for clear-cutting consequences
New research from the University of Alberta and the Canadian Forest Service has revealed the humble rove beetle may actually have a lot to tell us about the effects of harvesting on forests species.   view more (2007-06-13)

New genetic analysis forces re-draw of insect family tree
The family tree covering almost half the animal species on the planet has been re-drawn following a genetic analysis which has revealed new relationships between four major groups of insects.   view more (2006-10-27)

Species Diversity Less Dramatic Than Believed
A study published in the current issue of Science challenges the long-held belief that diversity of marine species has been increasing continuously since the origin of animals. Dr. Thomas D. Olszewski, a geology and geophysics professor at Texas A&M University, has been a part of the... view more (2008-07-08)

Battle of the sexes leads to a biological arms race
Boxes of chocolate and Valentine cards won't get you far in the animal world, where courting is considerably tougher. New research confirms earlier beliefs: an evolutionary "battle of the sexes" can lead to a biological arms race between males and females. We all know that males and... view more (2002-02-14)

Three new species of lemurs identified
Researchers have identified three new species of lemurs, the small, big-eyed primates native to the island of Madagascar.   view more (2006-02-23)

Reconstructing the biology of extinct species: A new approach
An international research team has documented the link between the way an animal moves and the dimensions of an important part of its organ of balance, the three semicircular canals of the inner ear on each side of the skull.   view more (2007-06-19)

Evolution of new species slows down as number of competitors increases
The rate at which new species are formed in a group of closely related animals decreases as the total number of different species in that group goes up, according to new research published in PLoS Biology.   view more (2008-03-25)

Great legs - rainforest birds` essential survival kit
Finely shaped legs are not just objects of beauty - some contain an important message. The legs of rainforest birds tell a story of environmental degradation. These bird's legs grow while they are in the nest being fed by their parents. When they leave the nest, they are fully grown. But the legs... view more (2002-11-12)

Rare Tibetan antelope listed as endangered
The Bronx Zoo-based Wildlife Conservation Society (WCS) today applauded a decision today by the U.S. Fish and Wildlife Service to list the Tibetan antelope, also known as "chiru," as an endangered species.   view more (2006-03-31)

New animal and plant species found in Vietnam
World Wildlife Fund scientists said today that the discovery of 11 new animal and plant species in a remote area in central Vietnam underscores the importance of conservation efforts in the ancient tropical forests of the region.   view more (2007-09-26)

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... view more (2002-10-30)
