Cane Toad Discovered in Perth Suburb (Nov 16, 2010)
Western Australia Department of Environment and Conservation.
The Department of Environment and Conservation is urging residents in Bayswater and surrounding suburbs to check their gardens for cane toads, after one was found in the Perth suburb. Cane toads have been listed by the Invasive Species Specialist Group of the World Conservation Union as among 100 of the world's worst invasive alien species. For more information, see the DEC Cane Toads site.

Cane
Toads are Evolving into Super-Invaders (Oct
19, 2010)
BBC Earth News.
Scientists have demonstrated
a "runaway
evolutionary effect" that is speeding
up Australia's cane
toad invasion; the invasive toads have
increased their rate of spread fivefold in
the last 70 years. The researchers found
that toads living at the very edge of their
range were "super-invaders", because
they have bigger front legs and stronger
back legs which enable them to jump and to
invade new areas. Their offspring inherit
this ability to move quickly into new territory.
The findings are published in the Journal
of Evolutionary Biology article Evolutionarily
Accelerated Invasions: The Rate of Dispersal
Evolves Upwards During the Range Advance
of Cane Toads. Cane toads are one of
the International Union for the Conservation
of Nature's top 100 invasive species.

Cairns
to Catch Toads for Cash (Jan 30, 2010)
Cairns News. Australia.
A cash prize will be offered for a whopper
cane
toad (Bufo
marinus) during a community effort
Mar 27-28, 2010 to control the invasive
species. The weekend collection will help
raise awareness of the effects cane toads
have upon native wildlife. Toads must
be delivered live to the weigh in. Last year's
bounty hunt resulted in the collection of
more than 6000 pests from the region!

Australia's
Biodiversity - Impacts of Climate Change (Aug

Australian
Government. Department of Climate Change.
New
report released -- Australia's
Biodiversity and Climate Change: A strategic
assessment of the vulnerability of Australia's’s
biodiversity to climate change (PDF | 3
MB). The report provids more compelling
evidence of the need to protect Australia's
natural environment for future generations -- not
only from climate change, but from such other
stressors as vegetation clearing and the
impact of invasive species (see Climate
change and invasive species (PDF | 296 KB).

Extinction
Crisis Looms in Oceania: Landmark Study (Jul 29, 2009)
University of New South Wales.
The study, in Conservation Biology, is the first comprehensive review
of more than 24,000 scientific publications related to conservation in the Oceanic
region. The authors identified six major threatening processes (habitat loss
and degradation, invasive species, climate change, overexploitation, pollution,
and wildlife disease) and developed a set of conservation policies for each threat.

Queensland Tim Mulherin announced that fish
species from 30 family groups would be added

Climate
change may wake up 'sleeper' weeds
(Mar 26, 2009)
Commonwealth to the Scientific and Industrial
Reaserch Organization. Australia.
Climate
change will cause some of Australia’s
potential weeds to move south by up to 1000km,
according to a report by scientists at CSIRO's
Climate Adaptation Flagship. Weeds cost Australia
more than A$4 billion a year either in control
or lost production and cause serious damage
to the environment.
