Hi Everyone,
Hope you had a great break!
A list of all 229Y Research Courses to be offered in 2005/06 in the Faculty of
Arts & Science will be available at the TUGS Office starting this Thursday,
February 24th.
299 courses (including GGR299) are part of the research opportunity program.
Students receive a credit course for supervised participation in faculty
research projects. If you are interested in gaining valuable research
experience, drop by the TUGS office from 12-4pm Monday-Thursday and take a
look at next year's listing!
If you have any questions, contact TUGS: tugs@xxxxxxxxxxxxxxxx or Susan
Calanza, Undergraduate Counsellor: calanza@xxxxxxxxxxxxxxxx Her office is on
the 5th Floor of Sidney Smith Hall.
Best,
Roza Tchoukaleyska
TUGS - President

POWERSHIFT: The Energy to Build a Better World Lecture Series
Helping the new U of T Sustainability Office to achieve its Goals â?? Our
Draft Strategic Plan
Dr. Beth Savan
Thursday, February 24, 2005
6-7pm in the Bahen Centre BA2179
Want U of T to achieve its potential to be a mecca of sustainability here
in Toronto? The administration does too and has just launched the new
U of T Sustainability Office with the mission of dramatically reducing CO2
emissions and promoting overall sustainability on campus. The
Sustainability Director, Dr. Beth Savan, is eager to tell you more about
the office and hear your thoughts and views about sustainability here at U
of T. Come out to the lecture to hear more about the office and join Dr.
Savan at the Peel Pub afterwards to talk with her about how best to
accomplish the Sustainability Office's goals. Don't miss this exciting
opportunity to have your voice heard at U of T!
Abstract:
The new Sustainability Office on campus has the ambitions mission of
dramatically reducing the University's energy use and therefore its
greenhouse gas emissions. How can we best achieve this goal, and what role
can students play? This presentation will outline our draft strategic plan
and will solicit your comments and suggestions about how to meet our
ambitious goals most effectively. Come and contribute your ideas!
Come out and learn how U of T profs are using their energy to build a
better world!

The Department is commencing its second set of interviews for
a faculty position in Physical Geography.
The Departmental Search Committee encourages all undergraduate students to
attend and provide their input.

MICROBIAL CONTROLS ON SOIL AND LANDSCAPE PROCESSES IN CANADIAN ECOSYSTEMS
Soil microorganisms perform vital tasks in terrestrial ecosystems
through the turnover of organic matter and nutrients. Ultimately
microbial activity mobilizes nutrients to sustain vegetation, while at the
same time is responsible for the net release of greenhouse gasses
from the terrestrial biosphere to the atmosphere. In only the past
decade, new molecular tools for rapidly characterizing signature genes
in soils and measuring key microbial enzyme activities have been
developed that allow for the scaling up of microbial ecology and
function in soils from the microsite to the landscape. This has led soil
ecology to become one of the last major frontiers to understanding
and improving management of ecosystems, especially under
increasing environmental change and demands for natural resources.
Peatland and forests are widely distributed,important Canadian
ecosystems. In Canada, peatlands represent the largest pool of
carbon in the terrestrial biosphere, likely the largest net sink for
atmospheric carbon dioxide, and a net source of atmospheric
methane. Peat is also a valuable natural resource that is
commercially mined, and efforts have been made to restore
biogeochemical functioning of harvested sites. Canada contains ca.
10 % of the world?s forests, and forestry is a vital component of the
Canadian economy. New harvesting techniques, including variable
live-tree patch retention, are currently being tested in hope of
improving forest regeneration.

EVALUATING ENVIRONMENTAL CHANGES IN THE SOUTHERN
CANADIAN CORDILLERA USING TREE-RING PROXIES
The varied topography and landscapes of the Canadian west afford
unique opportunities to sample and develop tree-ring chronologies
sensitive to different climate conditions from proximal sites.
Dendroclimatic studies based on a broad network of moisture and
temperature sensitive chronologies have been used to reconstruct
changes in the variability of precipitation, temperature and streamflow
at a number of sites in the region. Maps of precipitation variability in
the southern Canadian Cordillera and adjacent U.S. extend back to
1640 and are useful for viewing dry conditions of the early 20th century
in a longer context and for assessing historically important events from
a climatic perspective. This network of chronologies has also allowed
the investigation of more complex variables that integrate seasonal
changes in precipitation and temperature. Winter, summer and net
mass balance reconstructions have been developed for Peyto Glacier
in Banff National Park, Alberta. These records are 322 yrs in length
and offer a continuous insight into glacier variability over the Little Ice
Age that was not available previously. When compared with
streamflow reconstructions, possible causes of annual discharge
variability over the past 350 years (i.e. during periods of varying glacier
extent) can be investigated. The reconstructed mass balance series
can be compared with conditions in the Pacific Ocean over the past
100 years (almost triple the length of studies using the 35 year
measured mass balance series). The Peyto mass balance
reconstructions are also compared with similar records developed for
Glacier National Park, Montana to begin to address broader questions
on the timing and scale of glacier advances of the past 300 years
throughout this portion of the Rocky Mountains.

THE PAST IS THE KEY TO THE PRESENT: USING
PALEOECOLOGY TO UNDERSTAND ECOLOGICAL CHANGE
Paleoecology is the study of how ecosystems change on century and
millennial time scales. These long-term records supply important
evidence for paleoclimatic and other paleoenvironmental changes.
They also provide key insights into the mechanisms through which
ecosystems change and develop, and allow hypotheses about
ecosystem dynamics to be tested through time. Pollen grains
preserved in lake or wetland sediments have long been used to
reconstruct paleovegetation quantitatively; I show how advances in
pollen grain taxonomy and in the use of regional databases are
allowing pollen analysis to become a ?sharper? tool, increasingly able
to track species-level interactions through time. Paleoecological
techniques, including the analysis of pollen and diatoms (microscopic
aquatic algae) in peat records spanning the past 5000 years at a Lake
Erie coastal marsh, were used to test different hypotheses of wetland
initiation and subsequent plant community change. This research
indicates that geomorphic activity provides a fundamental control on
wetland development, but hydrological changes, driven both by
isostatic rebound and by climatic variability, acted to reorganize plant
communities episodically since the middle Holocene. The
paleoecological record from this wetland also provides a context for
modern day changes by showing which once-dominant plant
communities are no longer common and by identifying an invasive
plant species. I am now applying paleoecological techniques to
determine how aquatic ecosystems in two lakes in the central
Canadian Arctic have responded to Holocene climatic shifts.
Ultimately, paleolimnological records taken from a number of lakes
that have varied in diatom diversity and in productivity will be used to
test new ideas about the role of these in responses to disturbance and
in resilience.
