Course Description:
This is an upper level biology course designed to provide students
with exposure to the methods for examining molecular markers and how
these markers are used to address ecological and evolutionary questions.
Emphasis in this course will be placed on data analysis and inferences
from the data analysis. The course will start with a review of basic
genetics and the Castle-Hardy-Weinberg Equation. Various molecular
markers including allozymes and isozymes (protein electrophoresis),
restriction fragment (RFLP), DNA fingerprints (including RAPD & AFLP
markers), microsatellites (STR), single nucleotide polymorphisms (SNP)
and haplotypes (DNA sequencing) will be introduced but work with DNA
sequences and microsatellites will be emphasized. An overview of the
general methods, visualization of the resulting data, interpretation of data,
and strengths and limitations will be provided for each type of genetic
marker. The major topics covered in addition to genetic markers will
include Castle-Hardy-Weinberg equilibrium; genetic variability and genetic
differentiation; relatedness and parentage; indirect and direct estimates of
gene flow; estimation of effective population size; identification of
population growth or decline, lineage sorting and bottlenecks; and
detection of signatures of evolutionary events in population histories such
as inbreeding, selection and migration. To discuss these topics, various
other areas will be introduced including maximum likelihood, Bayesian
methods, coalescent theory and intraspecific phylogenetics and
phylogeography. In addition to class presentations, workbook exercises
will provide introduction and experience with methods of data analyses on
the topics listed above. These workbook exercises will require the use of
a number of computer packages and two weekly workshops in the
computer lab are scheduled. Knowledge and experience gained from
class presentations, computer workshops and workbook exercises will be
used to address questions on two take-home exams (mid-term and final).
Objectives:
1. Introduction to genetic markers including methods, visualizations,
interpretations and strengths and limitations.
2. Provide an intuitive grasp of relevant theory and analytical approaches
through lecture-style presentations, discussions, and primary journal
articles.
3. Obtain experience in using analytical methods to address ecological
and evolutionary questions through workbook exercises and takehome exams.
Grading:
Your grade in the course is determined by three components including
class participation, workbook exercises, and take-home exams. No
grading scale, simply those with the greatest number of accumulated
points will receive the highest grades. Graduate students should expect
additional problems for exercises, an additional workbook exercise, and
additional questions on take-home exams.
Exams: take-home (500 points each)

Text Books: Although there are now two relatively new text books in “Molecular
Ecology”, neither of these books provides the depth of coverage of most
topics that will be presented in this course. Both however, provide a
comprehensive introduction to the field and an overview of the topics
included.

Computer Workshop and Computer Programs
You will be expected to learn to use a lot of different computer programs in
this course, many of which are not particularly user friendly. These are not
programs that were developed for teaching labs but are the programs used by
researchers in the field of Molecular Ecology. To assist you with these computer
programs, a Computer Workshop will be held in the computer lab in room 001
Marsh Life Science to introduce you to these programs and assist you with
problems you may be encountering. Most of the programs we will be using are
“freeware” and you may download these programs on to your personal computer.
However, for the Computer Workshop you will need to use to computers in the
lab and have a 1 gigabyte or larger thumb drive on which I will be able to transfer
programs. You will need to have a thumb drive by the second computer
workshop (January 25 or 27). A few programs must be installed on computers
(will not run from a thumb drive), however, you may download may of these and
use them on your personal computer.
