This is a course for non-biology majors with two components, lecture and discussion section. We will explore biological principles at all levels of organization, from molecules, cells and organs to individuals, populations and the biosphere. Have you ever wondered…how basilisk lizards can literally run on water? …why we don’t yet have a vaccine against the HIV/AIDS virus? …why there is no rainforest in New England? …how bacteria help the Gulf ecosystem recover after the Deepwater Horizon oil spill? We will explore these and other questions to better understand how the living world works. Assessment includes evening exams, quizzes and written assignments. Gen Ed: BS.

An introduction to the workings of the cell, focusing on themes of cellular structure, dynamics and energetics. This course is intended for students interested in a broad interdisciplinary approach to the biological sciences: frequent connections to chemistry, physics and mathematics will be made as the cell, its inner workings and malfunctions, are explored. In the laboratory, students will work in teams to conduct multi-week inquiry-based experiments in a laboratory 'core facility' to complement and expand on the lectures. This first semester course is prerequisite for the second semester in a full year introductory course sequence for life science majors. Gen Ed: BS.

We will investigate the process of biological evolution and the evolutionary history of life on Earth.

In this class we will discuss concepts and applications of modern DNA technology including an introduction to the basic concepts pertaining to the emerging field of genomics. We will begin by describing key molecular methods (cloning, sequencing, blotting, PCR) and how they are used in gene analysis. We will then move on to consider how entire genomes are analyzed, and will familiarize ourselves with some of the basic bioinformatics' tools that are commonly used by working biologists. Finally we will consider the methods used to manipulate genomes as a means to determining gene function. This course is intended for sophomores and juniors, and should serve as a bridge between 200-level courses and more advanced, specialty courses (e.g., 500-level courses). Prerequisite: Biology 285 or Biochem 275.

Cellular and Molecular Biology Lab is a hands-on project-based course where students explore aspects of cell biology, particularly how proteins within cells are targeted to their correct intracellular location. The class will focus on targeting proteins to intracellular organelles. To approach this cell biological question, students will be using a host of current tools in the life sciences including, bioinformatics, DNA cloning, cell transformation, and microscopy. This course is meant to provide a laboratory perspective to many of the concepts taught in Biology 285. It is NOT necessary to have taken Biology 285, but students must at least be enrolled in Biology 285 concurrently with this course.

Most courses present the prevailing wisdom of the field as artistically rendered figures that summarize a large body of information and present it as dogma. However, that’s not how the field actually advances. Breakthroughs occur when researchers publish original research papers in peer-reviewed journals. Sometime the importance of the work is obvious at the time of publication and sometimes it takes many years for the true significance of the work to be appreciated. The “Great Papers in Biology” course is designed to allow students to read seminal papers in biology with the goals of: 1) understanding, in detail, how the experiments were conducted; 2) how the results were interpreted; and 3) how the work changed scientists understanding of biology. Papers to be discussed will represent a wide range of fields within Biology, including: developmental biology, genetics/genomics, neuroscience, cell biology, and the mechanisms of disease.

This three-credit will be limited to 20 upper division students who will be expected to read and discuss each of the papers. Students will be evaluated on the basis of their presentation and on class participation.

Introduction to experimental methods in ecology with an emphasis on rigorous experimental design, hypothesis testing, methods of data collection, and introductory data analysis. Laboratory will involve field trips, greenhouse experiments, and computer time.

Vertebrate collections are indispensable to the teaching of all whole organism biology courses. They are the repositories of Study of DNA, study skins, hides, preserved specimens, and comparative osteological material. Collections contain regional and global reference collections, provide secure storage for specimens of regional and historic importance, support a library of DNA samples and the specimens from which they were collected and also serve as the repository for type specimens. Maintenance of biological collections not only requires space and money but also require a highly dedicated and trained staff in order to be useful. Without constant maintenance even the smallest collections will deteriorate to the point of uselessness. Today many collections are being orphaned and/or discarded by colleges and universities. Qualified preparators, collections managers and curators are few and far between. During the course of this semester we will learn how to legally obtain, prepare, catalogue, and store new specimens and maintain an historic collection of vertebrate specimens. There will be one weekly lecture and at least 3 additional hours of lab per week. Lectures meet for 2.5 hrs. (6:00 ¬ 8:30 PM).

In this interdisciplinary course, we will explore the topic of imaging biological material, beginning with optics and basic microscopy. Students will perform hands-on exercises in the use of the light microscope, digital cameras, and image processing and quantification. Common pitfalls in imaging biological samples will be covered. Students will perform experiments to test and quantify various aspects of cell migration, cell cycle regulation, mitosis and endocytosis. Using the methods learned in the first portion of the class, students will design and complete a hypothesis-based experiment of their own design and present their findings. Bioimaging is a laboratory-based course. Enrollment is limited and requires permission of the instructor.

The goal of this laboratory course is to explore how researchers address modern biological questions through the use of model organisms. The course will be taught by a team of faculty whose own research employs these model systems to answer a diverse range of biological problems, including molecular evolution, plant development, yeast genetics, embryonic development and population genetics. Students will be introduced to several different model organisms that may include representative bacterial, plant, fungal, invertebrate, and vertebrate species. Lab exercises will employ sophisticated, state-of-the-art molecular methods and will tackle a variety of current biological questions.

Prerequisites: BIOLOGY 285 or BIOCHEM 275 or BIOLOGY 283, all with a grade of 'B' or better.

Animals have evolved a remarkable diversity of behavioral patterns, used in a wide range of ecological and social contexts. Our first goal in this course will be to examine the mechanisms responsible for the expression of behavior: for example, how do birds locate prey; how do crayfish avoid becoming prey; and how to crickets and birds develop species-specific communication signals? To help answer these questions we will make use of neurobiological, hormonal, genetic, and developmental perspectives. Our next goal in the course will be to examine the evolutionary bases of behavior, asking for example why animals move, forage, hide, communicate, and socialize as they do. To address these questions we make use of optimality theory and other behavioral ecological perspectives. Other topics in the course will include sexual selection, human behavior, and the role of behavior in establishing biodiversity. Prerequisite: introductory biology or psychology course; or consent of instructor and at least sophomore level standing.
