Scientists can now catalogue plants worldwideJuly 29th, 2009 TORONTO - Botanists have identified a pair of genes which can help catalogue plants worldwide, using a technique known as DNA bar coding. "Bar coding provides an efficient means by which we can discover the many undescribed species that exist on earth," said Spencer Barrett, professor of ecology and evolutionary biology at the University of Toronto (U-T), who led the study.
Some trees can camouflage themselves tooJuly 27th, 2009 SYDNEY - Like animals, trees can camouflage themselves too, a new study has found. One tree even kept changing the colour of its leaves to protect them from a giant flightless bird.
Noise pollution affects birds' nesting habitsJuly 24th, 2009 WASHINGTON - A new study has come up with the strongest evidence yet that noise pollution negatively influences the nesting habits of birds. The study also indicates that at least a few species opt for noisy areas over quiet ones, perhaps because of their vocalisation pitches, a reduction in nest predators and less competition from other song birds that prefer quiet environments.

Where do parasites go when their hosts become extinct?June 2nd, 2009 WASHINGTON - The loss of endangered species sends alarm bells ringing among conservationists, but what happens to the parasites they host?
Although most people would side with the panda over the parasite, which group should we worry about more?
North Carolina State University (NCSU) biologist Rob Dunn and colleagues examined the concept of co-extinction, the loss of one species upon the extinction of another. "Decline in host species could drive parasite species to switch onto alternative hosts, which could escalate the rate of emerging pathogens and parasites both for humans and our domesticated animals and plants," Dunn said.
Experts use videocameras to study tortoise behaviour in GalapagosMay 17th, 2009 QUITO - Scientists have fitted videocameras on three giant tortoises in Galapagos National Park in Ecuador to understand the behaviour of these ancient animals.
