… creatures. Research on the DNA of white sharks around the South African coastline shows that the population has extremely low geneticdiversity. This finding holds serious implications for their survival and more analysis is being done to try and understand this unexpected outcome and predict its consequences for the future of the species. What genetic diversity tells us Genetic diversity is an important indicator of the health status of a population in the wild: the higher the diversity, the …

Scuba divers in Bahamas find trove of extinct animal fossils and clues to a scientific mystery

… island of Abaco and, in many cases, become extinct altogether. A new report in the Proceedings of the National Academies of Science describes the discovery, and the authors believe it has implications for one of the great mysteries in science — the wave of extinctions in the Americas at the end of the Pleistocene as the climate changed, and human beings arrived. It may also help us think about our present and future impact on an increasingly stressed biosphere. To continue reading this …

Chernobyl’s lesson: Tell it to the birds

… Islands and had it photographed. The scientist and his team then decided to “collect” — read bump off — the very phantom creature it took him roughly two decades to find. A controversy has raged since. Ecologists have decried the killing as heartless and wanton, one claiming that it “sets a horrific precedent for future research”. In response, Filardi has been quoted justifying the action on two grounds. One, collecting specimens is “standard practice for field biologists”. Two, …

A 21st-century government must care for our nature and our future

… Australia has made something approaching this pledge before. In 1992 the Keating government signed the Convention on Biological Diversity. In doing so, it made a promise (later enshrined in national legislation), that: … the present generation should ensure the health, diversity and productivity of the environment is maintained or enhanced for the benefit of future generations.
