From
Emily Ogilvy ('12): This past summer I
researched the ant diversity in the burned versus the unburned
sandplain forest in Vermont with Professor Banschbach. I wanted
to find out if the ant communities differed in a burned area vs.
an unburned area and what role ants play in the succession of
the forest. Using the ant specimens collected from the General
Biology classes from 2008, Professor Banschbach and I keyed out
the ants to genus and species. After looking at over 700
specimens my results suggested that the burn sandplain forest
was more diverse. This fall I am continuing my research by
looking at the ants collected from 2006 and 2007.

From
Jason Berglund ('11):
This summer focused upon the study of the effects of South Asian
spices, such as tea or cloves, upon common cariogenic and
probiotic bacteria. The goal is to elucidate any connection
between what we eat and if there is a reason for why we eat
it--all from an evolutionary biology perspective.
From
Anna Gauthier ('11):
The overall goal
of my research is to explore the tempo and mode of virulence
change under various conditions to determine the mechanisms
involved with how virulence evolves over time. This summer, I
began to develop a working system using bacteria and
bacteriophage so that I would be able to produce reliable and
replicable results throughout my continued research during the
school year.
From
Chelsea Myers ('11): My summer research consisted of learning
new techniques in order to study the effect of hand sanitizer on
bacterial mortality and resistance. My summer certainly
concluded that hand sanitizer is generally effective. My studies
will continue this year to concentrate on growing and
quantifying resistant bacteria through generations of being
subjected to sanitizer treatments.

Three students worked with Mac Lippert
on projects related to the effects of transcription on
mutagenesis in yeast. Previous work has shown that elevated
transcription level through a gene is associated with increased
mutation rate at that gene locus. Each student worked on their
own project. Since DNA is double stranded, but only one strand
of each gene is transcribed, Kaitlyn Begins explored
whether transcription of the other DNA strand also increased
mutation rate. Kaitlyn reports that, �The summer
research experience was an amazing opportunity that I hope many
students are able to have in the future. My results yielded
some interesting results that aren't yet fully understood.
I'll be continuing my research
this semester on a slightly different question that arose from
my results from both prior summer research projects.�
A second student, Meghann Palermo,
explored whether transcription influenced chromosomal
rearrangements, which is when the end of a chromosome is deleted
or when two chromosomes fuse together. Meghann reports
that, �Summer research is a great experience! You get to learn
several valuable lab techniques such as planning out
experiments, running PCR reactions, and learning how to make
gels. Furthermore, summer research gives you the opportunity to
practice the data analysis skills you learn in your biology
classes. I still need to perform some statistical evaluations
before I can make any conclusions. I am hoping to continue the
research project this year, but am unable to do so until the
spring!�
A third student Ryan Gannon
explored whether a specific type of mutation occurred under
high-transcription conditions. Ryan reports that, �When
a cell undergoes transcription,
the double helical
structure of DNA is briefly open resulting in a non-transcribed
strand that is at risk for mutation. Cytosine, the most
unstable of the four DNA bases, can deaminate into uracil on the
non-transcribed strand during transcription. To say that summer
research is a rewarding experience is an understatement.
It's awesome to have the responsibility of conducting original
research and work along with the biology faculty and other
students also performing research. I will be continuing the
same research with Professor Lippert in the fall.�
From the research lab of Professor Mark Lubkowitz
Mike McDonough is testing the hypothesis that Norway Maples
are colonized by different mycorrhizael fungi than other
maples. The goal is to determine if Norway Maples form
different symbiotic relationships with fungi than native maples
and if this has contributed to their success as an invasive
species. Sara Williams is in the process of
characterizing genes responsible for acquitting nutrients in
epiphytes, or air plants-plants that do not root in the soil- to
understand how these organisms scavenge rain water for their
nutritional needs. Jake Withee is cloning genes known to
be involved in plant carnivory from close non-carnivorous
relatives to determine if the evolution of this trait is
primarily caused by how a gene is used as opposed to acquiring a
new function. Allen Hubbard is in the process of
identifying genes that are involved in moving nutrients in the
rice seed during germination. Specifically, Allen is trying to
identify genes that move small proteins from storage reserves to
the embryo during germination.

From the research
lab of Professor Declan McCabe
Summer 2010 saw room 315 Cheray bustling with the activities of
Saint Michael's College students and off-campus guests as they converted the teaching space to become The
Macroinvertebrate Lab (fondly known as The Bug Lab).
Students working with Declan McCabe this summer included:
Yeseira Lazz� (Universidad Metropolitana '11), Bridget Levine
(Saint Michael's College '12), Janel Roberge (Saint Michael's
College '12), Tyler Gillingham (Saint Michael's College '11),
Erin Hayes-Pontius (University of Vermont '11), Ram�n Pe�a
(Universidad Metropolitana '11); Natalia Santiago Merced
(Universidad Metropolitana '13). The team included three
returning students (Bridget, Erin, and Tyler) who played
leadership roles and helped train the incoming students. The team divided their time between field work and lab
work in support of the Vermont EPSCoR
Streams Project, and individual student-faculty research
projects. Most of the work involved sampling
and identifying macroinvertebrates both for
research projects and outreach to high school
teams from Vermont, New York, Rhode Island, Delaware, and Puerto
Rico. During early July, Macroinvertebrate Lab team members
were actively involved in training the high school teams to
conduct their own research in streams near their own schools.
Water
samples were sent for analysis
for phosphorus, suspended solids, and coliform bacteria.
Margaret Ecker (Saint Michael's College '12) was among the
students working in the water analysis lab at UVM on related
research projects and also providing water quality data for the
Streams Project. All of chemical, biological and physical
habitat variables were complimented
by land-use data generated using Geographical Information
Systems (GIS) layers that utilize satellite imagery and aerial
photographs.
An
immediate outcome of the summer work has been an expansion of
the set of
macroinvertebrate web sites tailored to specific stream
sites being sampled by partner highschools. All of the students involved
in the project are actively involved in preparing posters for a
spring symposium. The year-round research team includes Erin and Bridget who
earned internship funding for the academic year to continue
their projects. They have been joined by Scott Ritter (UVM
�11).
From the research lab of
Professor Adam Weaver -
Kristen Cowens and
Amanda Willette spent
the summer examining specific facets of the circulatory anatomy
and nervous system physiology in leeches. Together with
Professor Weaver, Kristen and Amanda set up a neurobiology lab
in which they collected video footage of the blood circulation
in a juvenile leech, recorded neuronal activity, and prepared
animals for future anatomical studies. They also discussed their
research and the characteristics of leeches with a group of K-6
students at the Schoolhouse Learning Center in South Burlington.
Two biology students also did
summer research with faculty in our Chemistry Department.
Marie Agan worked with
Professor Alayne Schroll on organic synthesis of FMOC
selenocystine and then adding a protecting group (2.4.6-
trimethoxybenzlyalcohol) to the very reactive nucleophilic
selenium on the amino acid. Once protected, the derivative
can be used to insert selenocysteine into polypeptides such as
enzymes like glutathione peroxidase, an enzyme used in cancer
research and drug discovery. Derrick Cumberbatch worked
with Professor Shane Lamos and used isotopic variants of a
nitrogen-containing compound called cholamine to do multiplex
analysis on carboxylic acids in biological systems. These
chemical variants have the potential to be very powerful
diagnostic tools in the future.
