Our backyards
contain numerous species of plants, animals, and fungi, but what is really
happening to the populations that live so close to us? Humans have created
unique, fragmented natural and semi-natural environments surrounded by human
development and agriculture. This course will focus on how natural populations
in these habitats function and interact with nearby natural areas, the effects
of humans, attempts at controlling
natural populations, our introductions of exotic species, and our shifting
views of what is natural versus unnatural in the gradation between urban,
suburban, and agricultural habitats. In the lab, students will study a
semi-natural local habitat, propose hypotheses related to the biodiversity and
ecology of the habitat, measure biodiversity and hunt for exotic species, then
make recommendations for ways to manage the habitat to better support local
populations and meet diverse human needs.

This
is an introductory course aimed at studying the genetics and evolution of
organisms. Along with major themes in
those areas, we will examine topics ranging from ecology and behavior to
physiology and biomechanics. A major theme of the course will be to understand
why biologists often use a few "model organisms" to examine topics
that are more widely applicable. Includes a lab. Prerequisites:

course takes an introductory look at the relationships between genetics,
environment, and biochemistry. It is intended for students with a strong
interest in science and is appropriate for biology majors. The course will
begin with an examination of heredity in both classical and modern molecular
contexts. It will then focus on the relationships between genes and proteins,
and the complex biochemical interactions that produce a phenotype. The course
will culminate in a discussion of the ways in which the environment interacts
with multiple genes to influence complex traits, for example schizophrenia, and
the modern methods applied to the problem of identifying the genetic components
of these traits. The laboratory will provide an opportunity to examine some of
the principles discussed in the lecture in more detail and to become acquainted
with some of the methodologies and instrumentation found in a modern biology
laboratory. Prerequisite:
successful completion of Q exam, and experience in high school biology and
chemistry.

Environmental Studies This
core course for biology majors is an introduction to the general principles of
ecology and evolution that, with genetics, form the core of biological
understanding. In addition to studying foundational ideas in both ecology and
evolution, we will explore modern topics at the boundary between these two
areas. We will consider, for example, how genetic variation among individual
organisms can influence ecological interactions, and how these interactions can
influence fitness. We will focus on a mechanistic understanding of processes,
using model-building to inform that understanding. Offered every spring. Prerequisite:
Successful completion of Eukaryotic
Genetics (Biology 201).

of this course is the relationship between the physical and chemical functions
of various organs and organ systems to overall homeostasis, with an emphasis on
human physiology. Systems examined include the central and peripheral nervous
systems, muscle, the heart and blood vessels, blood, the lungs, the kidneys,
the digestive system, the endocrine glands, and the reproductive systems.
Laboratory work provides practical experience in relevant topics of human
physiology. This course is appropriate for those interested in a career in the
health professions and others interested in animal biology. Prerequisites:
Biology 141-142, Chemistry 141-142; Chemistry 201-202 is recommended

This course examines the molecular and biochemical
mechanisms involved in processes relating to eukaryotic cellular organization,
communication, movement, reproduction, and death. These topics are considered
through close reading of the primary and secondary literatures. Discussions of review articles on particular
topics precede in-depth discussions of one or more research articles in those
areas. The literature is read with the objective of understanding the current
models describing cellular processes, as well as the experimental rationale and
the modern techniques used to probe fundamental cellular mechanisms and test
the models. The laboratory consists of a semester-long project in which a
cellular process is investigated. Offered in alternate spring semesters. Prerequisites:
Biology 201-202, and Chemistry 201-202.

Tropical ecosystems are among the most biodiverse, most threatened, and
the least studied in the world. This course will examine both practical and
theoretical aspects that are unique to tropical ecosystems, including the role
of geology, biogeochemical cycling, evolutionary processes and species
interactions. In addition, we will discuss issues related to conservation, such
as habitat fragmentation and climate change. This course will include lectures,
student presentations, and research projects. Students will design, conduct,
synthesize, and present a field research project. There will be a trip to
conduct the research projects in La Selva Biological Station in Costa Rica over
spring break. Additional costs will apply. Application form required. Contact
the instructor for more information. Prerequisites: Moderation, Bio 202 Ecology

In this seminar course, we will examine the topics of
sexual selection, mate competition, and mate choice, primarily in animals. We will look at classic models that have
shaped the study of sexual selection as well as recent outgrowths of those
models. A major theme of this course is
to look at how recent advances in genomic studies have changed studies of
sexual selection and sexually selected traits.
As a group, we may undertake one major laboratory project. Prerequisites: Bio 201 and Bio 202, Biostatistics encouraged.

The evolution of complex sociality remains one of the great, unsolved
mysteries in biology. Social evolution has generated tremendous examples of
cooperation, but also tremendous conflict between cooperating individuals and
between scientists attempting to explain their origins. This seminar will
investigate three major areas of conflicts in social biology: 1) conflicts
between scientists over the underlying causes of cooperation and eusocial
evolution 2) conflicts between parents and offspring over resources and
offspring phenotypes, and 3) conflicts between the sexes over resources and
mating decisions. Theories underlying sociality are currently in flux, as some
social researchers have returned focus to ecological benefits of cooperation,
while others continue to emphasize the role of kinship in promoting sociality.
Students will read seminal and modern papers that present important issues with
sociality, and discuss these issues in class. Students will be encouraged to
think critically about biological theory, and draw their own conclusions as to
how natural selection has led to a variety of social behaviors.

Students will study two conflicts using cavity-nesting ants as a model
organism. Ants that were collected the previous fall and overwintered will be
raised in a lab setting. At least one student will investigate why adults bite
their larvae and how that affects the caste fate of the larvae. Another student
will record sex ratios produced, and discuss how that may or may not apply to
genetic versus ecological influences on eusocial evolution. A third student
will use males and females produced by these nests to study mating behavior in
the lab, with particular focus to whether larger females choose larger males
when mating. At the same time, these nests will have been screened the previous
fall for the intracellular parasite Wolbachia, which may influence reproductive
decisions of their hosts. Therefore, two additional questions can be addressed
(by additional students or as a back-up for the above projects): whether
Wolbachia increases the production of females over males, and whether Wolbachia
influences the mating success of females, as can occur in other insects.
Co-requisite: Conflicts in Social Biology.
