I completed my undergraduate degree in
Zoology at the University of Guelph in 2008. I officially began my Masters here
at Western in September 2008, but I have been working in the Sinclair lab since
May, doing field work and preliminary lab work. My work will focus on the
physiological mechanisms used by the Emerald Ash Borer (EAB) to survive winter
temperatures. The EAB is an invasive beetle from Asia that has the potential to
devastate ash tree populations in North America. EAB spend the winter as
prepupae in chambers under the bark of ash trees. I will be tracking changes in
supercooling points and hemolymph contents such as polyhydric alcohols, sugars
and antifreeze proteins throughout the winter. This will allow me to determine
how cold tolerance changes throughout the winter. My data will be combined with
temperature data obtained from data loggers installed on ash trees in several
locations around Ontario to build a model that will help to determine if lower
winter temperatures will limit the spread of EAB in North America. Email me |
