- 2008 Australian Academy of
Science Boden Research Conference "Beyond the Platypus
Genome", 23-26 of November 2008.
We hope that this will be a great opportunity for the
Monotreme research community to interact and discuss
recent work in particular on molecular aspects of
platypus and echidnas.
As we are considering poster or mini-poster presentation
it would be great if people can let us know if they or
their students would be interested in presenting at this
conference.

- Call for unwanted marsupial
plasma samples
The scarcity of information on the effects of pesticides
on Australian native vertebrates constrains the
development of biologically relevant risk assessments in
Australia for the registration of pesticides. As part of
a larger collaboration between the University of
Wollongong and the Australian Plague Locust Commission (APLC)
looking at the ecophysiological effects of pesticides
used for locust control on Australian native
vertebrates, Bill Buttemer and I are investigating the
question of whether endemically old and unique
Australian vertebrate fauna display high sensitivity to
pesticides used for locust control. In turn, this has
provoked an examination of the acute oral toxicity of
the organophosphorus pesticide, fenitrothion for the
fat-tailed and stripe-faced dunnarts which has revealed
that these species are approximately 10-14 times more
sensitive to fenitrothion then any other mammals for
which LD50 values have been reported.
Previous authors have demonstrated that differences in
chlorpyrifos toxicity between young and adult Long-Evans
rats could be attributed to young rats having less
chlorpyrifos-oxonase (an A-esterase responsible for
hydrolysing chlorpyrifos-oxon, the active ChE
suppressing metabolite of chlorpyrifos) activity and
therefore having a lower capacity to detoxify
physiologically relevant concentrations of the
chlorpyrifos-oxon after exposure. The presence of
sufficient A-esterase activity to hydrolise the oxon
components of OP insecticides is a critical step in the
metabolism of, in this case, fenitrothion in mammals and
differences in the availability or functionality of
paraoxonase may likely be the reason why native
Australian marsupials studied here differ from other
mammals in their sensitivity to organophosphorus
insecticides.
Examination of how these animals differ in this regard
deserves further study and so, to this end, I am
currently collecting marsupial plasma samples for
analysis of their paraoxonase activity by Professor Clem
Furlong (University of Washington, USA). I have samples
from the dunnarts, Sminthopsis macroura and S.
crassicaudata as well as several bilby samples. I am,
however, keen to get hold of as wide a spread of samples
as possible across the marsupial taxa and would be
grateful to hear from anyone with spare marsupial plasma
from other species before travelling to the USA in
November this year. Alternatively if marsupial research
was planned investigating an aspect of the RBC component
of a blood sample, with the plasma being earmarked for
the rubbish bin, I would be more than happy to take the
plasma component off your hands. I am happy and willing
to travel (within reason) to pick samples up provided
they have been kept in either liquid nitrogen or at
-80C.
