Warming world holds new threats for Aussie wildlife

02.04.2008
Climate change is likely to transform many of Australia’s natural landscapes, according to a new study by CSIRO scientists.

The report, Implications of Climate Change for the National Reserve System, was prepared for the Federal Government, and released today by Environment Minister Peter Garrett.

Author Dr Michael Dunlop says climate change is forcing environmental scientists to rethink their approach.

Temperatures over Australia are projected to rise by about 1 ºC by 2030, and 1.8 ºC by 2070, relative to 1990 levels.

“Traditionally, conservation has focussed on preventing change or restoring landscapes toward a pre-European state, but we now have to accept that change is inevitable, and it’s happening quite fast,” he says.

Temperatures over Australia are projected to rise by about 1 ºC by 2030, and 1.8 ºC by 2070, relative to 1990 levels.“Some animals and plants will be found in places where they’ve never been seen before, and others will disappear from areas where they were once common, and for many regions the look, sound, and smell of the landscapes we are familiar with will gradually change.”

The report confirms that Australia’s 9 000 protected areas are critical for nature conservation in a warming world, but Dr Dunlop says new protected areas will also be needed.

“There’s a lot we don’t yet understand, but we know more species will have a greater chance to adapt and survive if we protect:

as many different types of habitat as possible;

larger areas of habitat; and

locations that have historically provided a refuge for biodiversity during times of climatic stress.

National Park rangers and local conservationists will be on the front line in helping nature adapt to climate change, and Dr Dunlop warns they may be up against some new and worsening threats.

“For example: it will be harder to provide enough water at the right times to maintain wetlands; mangrove systems will be squeezed between urban areas and rising sea levels; and more frequent, intense fires may turn some forests to woodland, and some woodland to grasslands.

“We need to be vigilant against new exotic weeds and pests that will benefit from changing climates.

“One increasing challenge will be deciding how to respond when native species turn up in new areas and threaten local species,” he says.

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Shape matters when light meets atom

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
