Date Time Farmers and scientists unite for pint-sized pygmies Fifty-two pygmy blue-tongues have been released on a farm in a southern area of the mid-north, 90km north of Adelaide, as part of a $400,000 Flinders University Australian Research Council Linkage project to save them from looming extinction as our climate warms. Pygmy blue-tongues are unique to South Australia and live in grasslands, predominantly sheep grazing land in the mid-north. Their population is endangered due to habitat limitations and limited dispersal ability with the skinks found from Kapunda up to Jamestown. “Modelling indicates these lizards are in danger of extinction in around 50 years’ time due to climate change,” says Flinders University’s Associate Professor Mike Gardner, lead researcher on the ARC project. ....
Date Time Positive signs of immunity after COVID-19 infection Australian scientists have described the evolution of immunity levels up to four months following COVID-19 infection, finding that while antibody levels drop dramatically in the first one to two months, the decrease then slows down substantially. The findings suggest that protective COVID-19 vaccines should ideally generate stronger antibody responses than natural infection. The research, led by Professor Stephen Kent from the Doherty Institute in collaboration with the University of New South Wales Kirby Institute and Flinders University, has been published in high ranking journal Nature Communications, The team, including University of Melbourne Dr Jennifer Juno, a Senior Research Fellow at the Peter Doherty Institute for Infection and Immunity (Doherty Institute), have been investigating how the immune system, particularly B and T cells, responds to the COVID-19 spike protein. ....
African Lion (source -Wikicommons: Clement Bardot) Recreational hunting – especially hunting of charismatic species for their trophies -raises ethical and moral concerns. Yet recreational hunting is frequently suggested as a way to conserve nature and support local people’s livelihoods. In a new article published in the journal One Earth, scientists from the University of Helsinki in Finland and Flinders University in Australia have reviewed more than 1,000 studies on recreational hunting – the first such attempt to summarize the scientific literature examining the biodiversity and social effects of recreational hunting globally. Co-lead author University of Helsinki Associate Professor Enrico Di Minin says while it might seem counterintuitive, there is evidence to suggest some recreational hunting can deliver environmental and social benefits. ....
