Judas camels betray their mates 25/2/2015

A MURDOCH University molecular ecologist says “Judas camels” fitted with tracking devices greatly enhance the chances of finding and subsequently culling wild camels (Camelus dromedarius) in Australia’s deserts.

His conclusions come after a close study of camel behaviour in the wild.

This is only possible in Australia because Arabian camels are technically extinct in their native habitat, Arabia and the Sahara.

Camels don’t spend their lives in the same family group – they constantly leave the groups they are in to socialise and mate with others.

Iconic flying saucer in mothballs – 12/12/2008

Whatever happened to the “space ship” that once stood at the entrance to Willeton’s Burren Dah estate?

willetonfuturo - Examiner 2008 12 12Originally acting as a sales office for the estate, it later served as the subdivision’s entry statement.

It featured on a Jebediah album cover, and in its later days was said to be the site of some late night teenage parties.

When I tracked it down in 2008 it was lying in bits in someone’s backyard. The site’s then occupant, Dennis Jensen MHR, claimed no knowledge of its whereabouts.

Warmer beaches influence sex ratios of loggerhead hatchlings 22/10/2013

Climate change could lead to sea turtles successfully breeding further south, a scientist says.

While instinct drives a mother turtle to lay her eggs at her own hatching place, cyclones sometimes take her a long way away when she is ready to lay.

She may have to make an emergency landing – and laying – on another beach when she is caught short.

Hotter summers are likely to make new beaches warm enough to incubate turtle eggs in future.

Dirk Hartog Island has the southernmost loggerhead turtle rookery.
