Sean is a research officer at the
University of
Canberra with an interest
in evolutionary ecology, physiological ecology and conservation biology of
reptiles and amphibians.
His talk relates to a project undertaken
throughout 2003-05 set out to determine by what mechanisms do water dragons
adjust their offspring sex ratios during range expansion and climate
change. Results (including those from ANBG) showed that
the pivotal temperature (the incubation temperature that divides the offspring
sexes) is not adjusted to produce viable sex ratios throughout various climates, but rather lizards adjusted
sex ratios by nesting in areas with different canopy openness
indices.
Field Naturalists
Monthly meeting venue: Division of
Botany and Zoology, Building 116, Daley Rd, Australian National University (Opposite Burton and Garran). Meetings start at 8 pm and are
followed by refreshments.
EDITORIAL
Next month we have a speaker on a very hot
subject. Dr Andrew Glikson, an Earth Scientist in the Australian National University, will talk about "Planet
H/eaters - a global warning" when he will explore the nature and origin of the
current climate change including the consequences of anthropogenic combustion
of the carbon products of more than 400 million years of biological
evolution.
