By Maggie Fox; editing by Todd EasthamWed Dec 15, 2010 WASHINGTON Dec 14 (Reuters) – Climate change is affecting the breeding cycles of toads and salamanders, researchers reported on Tuesday, in the first published evidence of such changes on amphibians. They documented that two species were breeding later in the autumn than in years past, […]
(PhysOrg.com) — The first detailed measurements of current extinction rates for a specific region have shown that birds are the best group to use to track the losses. The study also reveals Britain may be losing species over ten times faster than records suggest, and the speed of loss is probably increasing: the losses from […]
By Richard Gray, Science CorrespondentPublished: 9:15AM BST 03 Oct 2010 Frog populations are on the verge of dying out in some parts of Britain due to a disease which causes them to bleed to death. Common frogs, which are the most widespread species of frog in Britain, have suffered declines of around 80 per cent […]

By Michael McCarthy, Environment EditorTuesday, 20 July 2010 The frog-killing disease which is sweeping parts of the world is now wiping out amphibian species before they have even been described, new research has shown. Dramatic declines in amphibian populations in the Americas and Australia have been known since the late 1980s, exemplified by the […]
WASHINGTON, DC, April 29, 2010 (ENS) – World leaders have failed to fulfill their commitments to reduce the global rate of biodiversity loss by 2010, and have instead overseen “alarming” biodiversity declines, finds the first assessment of how the targets expressed in the 2002 Convention on Biological Diversity have not been met. Since 1970, human […]
By Rhett A. Butler, mongabay.comMarch 31, 2010 Urbanization may be having unexpected impacts in the Amazon rainforest by leaving forest areas vulnerable to exploitation by outsiders, report researchers writing in Conservation Letters. Conducting field surveys during the course of 10,000-kilometers of travel along remote Amazon rivers, Luke Parry of Lancaster University found that a sharp […]
By Peter Gardiner | 5th March 2010 A CHEMICAL linked to sex changes in frogs and chemical castration has been found in samples taken from the Noosa River system. However, fish health expert Dr Matt Landos said the levels of atrazine, which is used as a weed killer, were not of sufficient concentration to be […]
By Maggie Fox, Health and Science EditorWASHINGTONWed Mar 3, 2010 3:36pm EST WASHINGTON (Reuters) – Atrazine, one of the most commonly used and controversial weedkillers, can turn male frogs into females, researchers reported on Monday. The experiment is the first to show such complete effects of atrazine, which had been known to disrupt hormones […]
