Jennifer Marohasy - June 20, 2008 - 10:42pm

A new study by a team of scientists specializing in zoology and animal health reported, "analyses found no evidence to support the hypothesis that climate change has been driving outbreaks of amphibian chytridiomycosis."

The study was published in the peer-reviewed PLoS Biology, a journal of the Public Library of Science:

There are claims that the presence of too many sheep, cattle and kangaroos are damaging Australia’s rangelands and that commercial shooting of kangaroos will reduce overall grazing pressure. Read more »

On this Queen's Birthday Public Holiday, I thought that I would issue a challenge to our Politics & Environment Weblog community:

Bumblebee Success

Jennifer Marohasy - May 31, 2008 - 11:31pm

I'm into my second year as a member of The Bumblebee Conservation Trust. I was considering burying a bumble bee nest box in my garden, but the other day I noticed that there is no need - the little critters have already made a nest utilising a pre-existing hole in a flower bed next to our conservatory.

Photographing this roosting pair of Wompoo Fruit-Doves Ptilinopus magnificus was simply irresistible. Over the years, I have seen many asleep, but never so low to the ground.

They are large doves, reaching almost half-a-metre and are richly coloured, with white head, purple breast, green wings with a conspicuous yellow stripe and bright yellow undergarments. Read more »

Leseur’s Frog (Litoria lesueuri) emerge after dark from their diurnal concealment amongst leaf-litter on the dark-brown forest floor, where they elude the predatory appetites of a formidable avian oversight. Read more »

Humpback off Sydney, Australia

Jennifer Marohasy - June 4, 2008 - 9:41pm

Each year some humpback whales migrate from the Antarctic to north eastern Australian waters travelling a distance of some 10,000 Kilometres. Some pass Sydney and even enter the harbour.

I understand there is lots of food in the Antarctic, but it's a bit cold for birthing with baby whales likely to freeze in Antarctic water.

What is Wilderness? (Part 4)

Jennifer Marohasy - May 26, 2008 - 7:09pm

"Wilderness thus became the domain of the nobility, an environment where they alone could develop and display a number of artistocratic qualities. Friction arose between the peasants - inhabitants of open, unobstructed outdoor spaces - and the noble occupants of the forest, and that friction persisted as long as the peasant felt excluded from a portion of the landscape that he believed was his by right of heritage."

Cyclosa Spiders and Stabilimenta

Cyclosa1.jpg

When I first spotted this messy web, I could barely make out the spider. In its own right, it was tiny; a mere 3-4 mm long, but in the circumstances of its concealment, it was marvellously blended into the broader clutter of debris, at the centre of the stabilimentum (conspicuous feature of silk).
