Winjanna Gorge: Survey nets plenty of crocs

Bunuba Rangers and wildlife officers have caught and released about half the freshwater crocs in two dry-season pools.

They took measurements and genetic samples in a bid to learn more about the crocodiles before cane toads arrive.

New methods to detect toxic mine water seepage

Researchers say they have found a reliable new way of predicting whether water seeping from a mine into a creek is toxic.

After studying an east Kimberley nickel mine they say toxins only seem to affect animals in the creek in the late dry and early wet seasons.

This, they say, is easily predicted by seeing how readily the water samples conduct electricity.

This appears to be good news as it is much easier to control the flow of water at these times.

There was no legal requirement to conduct this research.

Kimberley dolphins keep to themselves

Scientists have been studying genetic diversity in Kimberley and Pilbara dolphins.

It looks as though Australian snubfin and Indo-Pacific dolphins tend to stay in small populations that keep pretty much to themselves.

DNA from skin samples collected at Cygnet Bay, Roebuck Bay, Dampier Archipelago and North West Cape high genetic similarity within each local group.

Books: Action plan for Australian Mammals

The rufous hare wallaby used to be common in the desert south of Balgo.

It probably died out in the 1960s.

In a new book Action Plan for Australian Mammals, the authors say Australia has had the highest mammal extinction rate for any continent since the 1840s.

They detail action plans for every known Australian mammal species.

Oscar Ranges ‘partly buried’ say geologists

The Oscar Ranges are partly buried – the structures continue, under the surface, to the Yampi Peninsula.

Scientists have discovered this and other facts while surveying the Oscar, Leopold and Napier Ranges, parts of which most likely contain copper and gold.
