Can feces save the species?
It's a tough job, but somebody, or at least some dogs, have to do it. In the Cerrado region of Brazil, four dogs trained to detect animal feces by scent are helping researchers monitor rare and threatened wildlife such as jaguar, tapir, giant anteater and maned wolf in and around Emas National Park, a protected area with the largest concentration... view more...

Sharks in danger
There are 370 species of shark, each with their own particular habitats and behaviours. Most sharks are slow to reproduce and do not have large numbers of young. They are therefore particularly sensitive to predation or large losses. Caught as accidental by-catch (estimated at 3000 per day), sharks are also fished for their fins (for food),... view more...

FSU scientist warns North Atlantic right whale facing extinction
The North Atlantic right whale's future looks grim if the current mortality rates continue, according to Florida State University assistant professor of oceanography Douglas Nowacek and a group of fellow scientists from across the nation. view more (2005-07-25)
LSU researcher first to demonstrate link between bird songs and habitat change
Elizabeth Derryberry, post-doctoral researcher at the LSU Museum of Natural Science, has found a link between alterations in bird songs and the rapid change in the surrounding habitat. view more (2009-06-15)
Why does species diversity vary so much?
The diversity of life varies predictably with climate and is greatest where it is warm and wet (the humid tropics). But the question "why" has puzzled biologists for over a century. In the December issue of Ecology Letters, Currie and colleagues examine three hypotheses about the origin of climatic gradients of diversity. The... view more... (2005-01-11)
Jeepers Creepers! Climate Change Threatens Endangered Honeycreepers
As climate change causes temperatures to increase in Hawaii's mountains, deadly non-native bird diseases will likely also creep up the mountains, invading most of the last disease-free refuges for honeycreepers - a group of endangered and remarkable birds. view more (2009-05-27)
Manipulating biotope space can enhance beneficial biodiversity effects
Using diverse plant mixtures instead of monocultures can increase yield and other ecosystem goods and services on which humans depend. Recent studies showed that such beneficial effects of biodiversity depend on complementarity between species in resource use, as is the case if species root in different soil depths. This knowledge led to the... view more... (2004-06-10)
Looking beyond biodiversity to explain community invasibility
Most existing experimental and theoretical studies suggest that diversity is an effective barrier to plant invasion. However, these studies may be limited in their generality, because they involve relatively small numbers of species or examine only short time periods. To evaluate how invasions are controlled in more realistic situations, Meiners,... view more... (2004-02-05)
Common garden plant threatened by climate change
Cyclamen, a common, pretty garden flower, is at risk of extinction because of climate change. In a study published today in the open access journal BMC Evolutionary Biology (http://www.biomedcentral.com/bmcevolbiol/), researchers show, using mathematical modelling, that the ideal climate for Cyclamen will become increasingly rare and might have... view more...

Scientist warns of threat to last stronghold of endangered turtle
A major conservation effort, led by Dr Brendan Godley of the University of Exeter, has just got underway to help protect endangered leatherback turtles which nest in Gabon, West Africa. view more (2006-03-07)
Misclassified for centuries, medicinal leeches found to be 3 distinct species
Genetic research has revealed that commercially available medicinal leeches used around the world in biomedical research and postoperative care have been misclassified for centuries. view more (2007-04-12)
Deft diving turtle tactics
How do turtles survive long trips across the ocean? At the Society for Experimental Biology conference on Friday 12 April Ms Corinne Martin (University of Wales Swansea) will present evidence of energy-saving diving patterns adopted by green turtles to survive long ocean trips. The turtles breed at Ascension Island, undertaking long-distance... view more... (2002-04-04)
Genetic Analysis of Asian Elephants in India Reveals Some Surprises
Researchers in India and from The Earth Institute at Columbia University have discovered that one of the few remaining populations of Asian elephants in India is actually two genetically distinct groups. view more (2005-12-20)
Lifeline for vultures from breeding centre plan
Conservationists say six major breeding centres will be needed, for three species of vultures, if they are to be saved from extinction in the Indian subcontinent. view more (2004-09-29)

A question of height
Intelligent countryside management could improve the survival chances of animal and plant species threatened by climate change. view more (2009-07-06)
Notre Dame study provides insights into how climate change might impact species' geographic ranges
A new study by a team of researchers led by Jessica Hellmann, assistant professor of biological sciences at the University of Notre Dame, offers interesting insights into how species may, or may not, change their geographic range - the place where they live on earth - under climate change. view more (2009-06-24)
World interest in Australian fishery impact test
An Australian method for assessing the environmental impact of marine fisheries has caught the eye of fishery management agencies worldwide. view more (2009-10-28)
Microchip saves rare turtle from soup-pot
An extremely rare "royal" turtle narrowly escaped a trip to a Chinese soup-pot, thanks to a tiny microchip implanted in its skin, according to experts from the New York-based Wildlife Conservation Society (WCS), who rediscovered the species four years ago in Cambodia. view more (2005-07-19)
How butterflies got their spots: A 'supergene' controls wing pattern diversity
Butterflies are known to employ some interesting convergent evolutionary tactics to survive-some nonpoisonous species have similar wing patterns to those of noxious species that predators avoid. view more (2006-09-26)
