A new study by researchers at Macquarie University has shed light on why blue tongue lizards have such an outrageously coloured tongue, given that the vast majority of lizards have a regular pink tongue.
Hugh Possingham and his team are making conservation more efficient. They’re helping to save less fashionable threatened species by getting more bang for the bucks donated to cute and cuddly species.
The team of ecologists and mathematicians in the Australian Research Council Centre of Excellence in Environmental Decisions (CEED) worked with the New Zealand government to assess how to better spend money that is donated to conservation. They’ve shown that by protecting habitats shared by several different species, the money donated to charismatic ones can be stretched further to save other species as well.
“The way we currently attempt to save species is inefficient, choosing species that are popular or charismatic, like koalas and tigers, over those that are less well known or even ugly, like the blobfish,” says Hugh, ARC Laureate Fellow and Director of CEED.
“Trait-based ecology” enables Macquarie University’s Mark Westoby to explain patterns of species occurrence and abundance and to understand the impacts of climate change and changing patterns of land use. He received the $55,000 NSW Scientist of the Year.
Nanocapsules for drugs delivery: Frank Caruso is making miniature capsules that could better deliver drugs for cancer, AIDS and cardiovascular diseases. He won one of the 2014 Victoria Prizes for Science & Innovation worth $50,000.
Not all honeybee species think like the common western hive bee when it comes to deciding on a place to nest. Some are capable of making faster collective decisions, according to James Makinson and his University of Sydney and Thai university colleagues.
Water sampling devices are keeping watch around the clock for toxic discharges into Melbourne’s creeks and stormwater drains, thanks to Victorian researchers at the Centre for Aquatic Pollution Identification and Management (CAPIM), based at the University of Melbourne.
And, they are also developing a new range of aquatic critter-containing sensors.
Dr Tracy Ainsworth’s research is changing our understanding of the tiny coral animals that built Australia’s iconic Great Barrier Reef. Tracy and her colleagues at James Cook University in Townsville have found that the process of coral bleaching is a far more complex than previously thought, and begins at temperatures lower than previously considered. And she’s done so by applying skills in modern cell biology which she picked up working in neuroscience laboratories.
Her achievements won her a $20,000 L’Oréal Australia For Women in Science Fellowship in 2011, which she is using to study the low light, deep water reefs that underlie tropical surface reefs at depths of 100 metres or more. Continue reading The complex life of coral→
Climate change will impose a complex web of threats and interactions on the plants and animals living in the ice-free areas of Antarctica.
Increased temperatures may promote growth and reproduction, but may also contribute to drought and associated effects. These scenarios are explored in a new book, Trends in Antarctic Terrestrial and Limnetic Ecosystems: Antarctica as a Global Indicator, co-edited by Australian Antarctic Division biologist, Dr. Dana Bergstrom.
