Physiology of the major systems of the human body in health and disease. Intricacy of the human body; good health practices. Collateral issues include birth control, sexually transmitted diseases, nutrition, and health risks associated with drugs and smoking. For nonscience majors; not for Biology major credit. Gen Ed: BS.

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.

We have two goals in this course. The first, and most important, is to introduce undergraduate Biology students to some of the many fascinating aspects of Plant Biology, especially as these differ from animal biology. For instance, did you know that plants are moving (on a large scale) all the time? It’s the truth, but in a very different time scale than we animals use. How do plants do that without the benefit of muscles and skeleton? Have you ever thought about how, in the absence of a pumping heart, plants’ circulatory systems work? After all, the water at the top of a tree got there from roots in the ground, but no pump was involved. Plants don’t have an immune system, and yet, they ‘stand and fight’—literally rooted to the spot—taking on all types of pathogens, as well insects and other predators. What strategies do plants use to overcome these attacks? Have you ever wondered about how biotechnology is used in agriculture? We have all heard news stories about GMO’s (genetically modified organisms). What are these and what makes them useful or dangerous? These are the types of topics we will be covering in this course. The second goal for this course is to provide a convenient way for UMass Biology majors to accomplish their plant biology course requirement. The course is open to any student who has successfully (with a C or better) completed the Introductory Biology series Biol 151, 152 & 153.

This fundamental ecology course emphasizes the quantitative skills needed to understand and conduct field research. The lectures introduce major ecological concepts, local vegetation types, and methods and techniques of gathering and analysing data. In laboratories, students collect original data at sites in the Connecticut Valley and write an original scientific paper. Prerequisite: an introductory biology course or consent of instructor.

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.

This course focuses on the ecology, physiology, taxonomy, and behavior of organisms that inhabit the New World tropics. The centerpiece of the course is a nine-day field trip to Belize. The trip takes place over spring break and includes intensive exploration of marine and coastal habitats. Pre-requisite: At least one year of college biology courses, on-line application, and permission of instructor.

The course provides an overview of the systematics, anatomy, and evolution of all the major, living lineages of amphibians and reptiles, with an emphasis on the herpetofauna of Eastern North America and New England. The laboratory is organized around three approaches: anatomical studies; studies of live organisms; and studies of regional and global amphibian and reptile diversity. If weather permits, there will be one field trip near the end of the semester. Some dissection is required. Prerequisite: Biology 521 or permission of the instructor.

Lecture: origin of birds, speciation, diversity, flight, territoriality, migration, navigation, communication, conservation. Lab: bird identification, anatomy, field studies. Text and field guide required. Lab practicals, 2 lecture exams plus final. Prerequisite: upper level biology course or consent of instructor.

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.

This course will explore animal communication from several biological perspectives. We will explore how animals use different modalities of communication (sound, smell, electricity, etc.) and how these modes of sending and receiving information are limited by environmental constraints and their functions. We will look at the physiological and anatomical aspects of signal production and perception. The class will discuss the different types of messages encoded in signals and how they evolved. We will explore the evolution of sexually selected forms of communication (antlers, bird song, etc.) and the theories that attempt to explain their function and evolution. The lectures/discussions will draw on examples from a diverse selection of animals (insects, fish, birds, and mammals). Students will also work on projects where they will learn how to analyze and interpret different forms of vocal and visual communication.

This course deals with evolutionary processes on a molecular and genetic level and provides training in analytical methods related to detecting genetic variation, phylogenetics, recombination, horizontal gene transfer, comparative genomics, and the analysis of microbiomes. The course contains three intellectual parts: genetic variation (mutation process, evolutionary rates, the molecular clock, and selection and neutral evolution at the molecular level), genome evolution (genome size, the evolution of chromosomes, the evolution of introns, gene/genome duplication, genome reduction, transposons, retroelements, gene conversion, and horizontal gene transfer) and evolution of genetic systems (the evolution of sex and sexual reproduction, recombination rates, sex ratios, genomic conflict, viral RNA genomes and bacterial transduction, transformation and conjugation). This course will also include discussion of the social, ethical and legal issues surrounding genetic technology and evolutionary biology.
