Forget your plastics. There is a naturally occurring material with better properties. It is produced in the nests of the Australian masked bee. The substance is resistant to fire and repels water. Furthermore, it is very strong. A company called the Humble Bee located on New Zealand is reverse-engineering the cellophane-like material in an attempt to create a biodegradable substitute for plastic.  If successful, world pollution will be substantially reduced. We are so dependent on things made from oil. The little bees sourced from Noosa in Queensland hold out great hope for a reduction in such products. A way of trapping the Hylaeus nubilosus has been developed by Chris Fuller of Kin Kin. Veronica Harwood-Stevenson has spent her house deposit and winnings from the Wellington Regional Economic Development Agency's Bright Ideas Challenge on the project. It is in the early stages. Ways of manufacturing are being studied. The aim is to initially make outdoor apparel and ...

Corals at high-latitude locations in Australia, i.e., towards the south, can change their chemistry in order to adapt to colder conditions. Unfortunately, the sea is heating up not cooling down. The analysis was done by the Australian Research Centre (ARC) at the University of WA. (Australia western). A warmer ocean could be expected to slow down coral growth in Bremer Bay but the animals altered their chemical composition. Indeed, they are flourishing. It seems that growing in a cold condition is what they do best. The two-year study showed that it is only tropical reefs that are under threat. There is more food available in cooler regions. By extrapolation it can be surmised that corals situated in hotter areas get less nutrition with global warming. % ai corals za high-latitude oh reefs gu internal ex coral el chemistry oi growth ta temperatures % + a corals i high-latitude oh reefs ah internal by coral id chemistry my growth ax temperatures as ross an cooler am wester...

There are 1,200 species of the genus Pheidole . Each has developed to exist in a particular niche of the ecosystem. In a study of 300 species it has been found that certain species evolved similar characteristics independently. Species proliferated dramatically - from one to 600 species in the Americas. The evolutionary goal was to dominate all niches, first in the New World then in the Old. Expansion across one was independent of the other. Evolution took its own course. Ants are essential for healthy ecosystems. They aerate the soil, disperse seeds and help move nutrients. In biomass they equate with all vertebrates. Their study is indeed important ✴ Biology by Ty Buchanan ✴ http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://adventure--australia.blogspot.com/atom.xml . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

It was believed that the Tasmanian Tiger perished in mainland Australia due to the dingo taking over their habitat. New findings show the dingo did not directly compete with the marsupial dog. They had different ways of getting their food. Dingos were brought to Australia from Asia in recent times. It is not native to Australia. The demise of the Tasmanian tiger on the larger part of Australia 3,000 years ago was coincidental. Settlers in Tasmania feared their cattle and sheep would be slaughtered so they eradicated the quite timid animal in the early twentieth century. Dingoes are wild dogs that run for long periods running down their prey. Tasmanian tigers were not distance runners. They ambushed sick and young animals. The tiger's skeletal structure was more like cats than dogs, particularly the elbow joint which was feline in character. The dingo has elbows that lock, while the marsupial dog had a flexible joint. This undermines the theory that the Tasmanian tiger fil...

Evidence of the existence of specialised ancient marsupials have been found in Australia. They had teeth that were "hammer-like" for crushing snail shells. Lizards living today in rain forests have similar teeth. They had premolars like the teeth in humans located between the molars and canines. Researchers could not determine at first what the strange teeth were used for. It was the first time that such teeth had been found in marsupials. Like the Tasmanian tiger a marsupial which filled the role of native dog in Australia, so this marsupial more than 10 million years ago, lived in the niche that the pink-tongued skink holds today. This wet rain forest lizard is quite large, about 40 cm in length, so it's ancestor would have been a tough competitor. The extinct marsupial became extinct when the weather changed in Australia and inland rain forests receded toward the coast. Lizards could survive in the new environment. The marsupial could not.
