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:

Ann Novek lives in Sweden. She was once a medical student, but quit to work as a wildlife rehabilitator. She works mostly with birds, and has a special interest in helping birds affected by oil spills.

Ann has also been a supporter of this blog, sending in wildlife photographs and also information about whaling. My favourite wildlife photograph from Ann was probably of the Arctic Fox. 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 5)

Jennifer Marohasy - May 27, 2008 - 10:29pm

"Absolute wilderness is those boundless places in the eye of the mind of the beholder where no human footprints can be found and for which all those enter there and become lost have no hope of rescue. Only the most reckless trapper or sibylline shaman venture into the wilderness, as a pebble falls to the bottom of the deepest pool, in the hope of returning to civilization with a fortune in furs or a secret wisdom or allegory thereof.

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.

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."
