Early Advising: Those students considering a concentration in biology should consult a departmental adviser early in their first year to discuss appropriate course sequences. After declaration of the major, no NRO work is permissible in the major.
Postgraduate Work: Students considering graduate school or other professional schools should be aware that such schools usually require courses beyond the minimum biology major requirements. In general, students should have at least a full year of organic chemistry, a year of physics, computer science, statistics and calculus. Students are urged to begin their chemistry and other correlated sciences coursework as soon as possible, since this will assist them in successful completion of the biology major. Students should consult with the chair of biology or the pre-medical adviser at their earliest opportunity.
Further Information: For additional information on research opportunities, honors requirements, etc., please see the biology department. http://biology.vassar.edu/
Advisers: Any of the faculty members of the Biology Department can serve as Major Advisors. Students who have a preference for a particular faculty adviser may ask that individual whether s/he would be willing to serve as adviser.

BIOL 105 - Introduction to Biological Processes Semester Offered: Fall and Spring
1 unit(s)
Development of critical thought, communication skills, and understanding of central concepts in biology, through exploration of a timely topic. The content of each section varies.
Topic for 2018/19a: Genetically Modified Organisms. From corn engineered to be herbicide-tolerant to salmon engineered to grow at twice the usual rate, genetically engineered organisms (or GMOs in common parlance) have continued to be in the news and spark controversies. In this course we use examples of GMOs to explore key principles in biology, though for the purposes of this class we use the term “GMO” very loosely. We study examples of both human engineered and random changes to DNA and their outcomes. We cover the key principles of genetics, evolution, ecology, and cellular metabolism by exploring “GMOs” in the context of biofuel production, agriculture and the spread of malaria. Jennifer Kennell.
Topic for 2018/19a: Let’s talk about sex. What does it mean to be “male” or “female”? What about transgendered or intersex? In this course we learn fundamental biological principles and processes by examining the evolution, cell biology, endocrinology, genetics, and physiology of mechanisms underlying sexual determination and differentiation. We also explore current topics in sex determination and differentiation across non-human vertebrates to examine differences in mechanisms underlying the development of sex. Kelli Duncan.
Topic for 2018/19a: Pets, Crops and Livestock: Biology of Animal and Plant Domestication. For at least nine tenths of its existence, our species survived by hunting wild animals and gathering wild plants. Then, about eight to 10 thousand years ago, our ancestors from at least seven different regions of the world independently domesticated certain species of wild animals and plants. These transitions from foraging to farming were the greatest events in our cultural history. From a biological perspective, domestication is an evolutionary process, a long-term selection experiment, that has affected both domesticates and ourselves. By examining domestication from a biological point of view, you should gain a better understanding of central biological concepts and improve your abilities to obtain, understand, critically evaluate, and communicate biological information. Mark Schlessman.
Topic for 2018/19a and b: Wild Canids and Domestic Dogs. This course explores the evolutionary diversity of dogs, both wild and domestic. We discuss the evolution of dogs from wolves as well as the artificial selection used to develop different dog breeds. To fully understand these evolutionary changes we explore topics such as the bio-chemical pathways involved in aggression and the genetics of coat color. Specific dog breeds are used to examine topics such as the physiology of performance and the genetic basis of disease. We also examine the diversity of wild canids from a conservation perspective, examining how their ecology interfaces with current population and genetic constraints. Meg Ronsheim.
Topic for 2018/19b: The Biology of the Human Microbiome. The human microbiome consists of the bacteria, eukaryotic cells and viruses that inhabit our bodies. These microbes outnumber our human cells by as much as ten to one and their genes may outnumber human genes by over a hundred to one. Once ignored, increasing evidence indicates that an appropriate balance of these microbes plays an essential role in human health. This course focuses on the interactions of the bacterial microbiome and their hosts as a framework for understanding basic biological principles. These include the biochemistry, structure, and function of cells, metabolism, genetic variation, evolution of the host-bacterial relationship, antibiotic resistance, and biodiversity, as well as the impact of diet and antibiotic use on the microbiome and consequences for health and disease. Elizabeth Collins.
Topic for 2018/19b: The Biology and Biomechanics of Spiders.Spiders are amazing due to their ability to stick to walls, spin incredibly strong webs, and create mass hysteria when found in your bedroom. This diverse set of predators have evolved to survive in nearly all environmental conditions and serve as a wonderful model to study biology and material sciences. In this course, we learn about the fundamental principles of biology such as cellular structure, physiology, genetics and inheritance, ecology and evolution in order to shed light on these misunderstood critters. In addition, we discuss the scientific method and how we are presently using it to make human life easier through biomimicry, learning from nature. Could a spider web stop a bullet? Which spiders can kill us? How realistic are Spider man’s powers? Would Gwen Stacy have really died? Which spiders are the best dancers? These are only a few of the questions we answer. Candido Diaz.

BIOL 275 - Paleontology and the Fossil Record Semester Offered: Fall
1 unit(s)
(Same as ESCI 275 ) Paleontology isn’t just a “dead science”- by studying processes that have occurred in the past, we can deepen our understanding of the current biota inhabiting the Earth. Conversely, by studying the modern distribution of organisms and the environmental, taphonomic, and ecological processes that impact their distribution and preservation, we can enhance our understanding of the processes that have controlled the formation and distribution of fossils through time. In this course, we explore the methodology used to interpret the fossil record, including preservational biases and how we account for them when studying fossil taxa. We also explore large-scale ecological changes and evolutionary processes and discuss how they manifest across geologic time, and how these relate to Earth’s changing fauna. We additionally learn about how paleontology has developed as a field in the context of different historical and social perspectives. Lab exercises focus on applying paleontological methods to a variety of different fossil and recent samples.

Emphasis is placed on current models, issues, and research areas, and course material is drawn largely from primary literature.
Topic for 2018/19a: Epigenetics. Most cells in our bodies contain the same set of DNA, yet there are ~200 different cell types, each with unique patterns of gene expression. How do those cells establish and maintain their identities? How do environmental factors such as temperature, nutrition and social stress exert long lasting effects on organisms and their progeny? The field of epigenetics is shedding new light on these and many other interesting questions in biology. Epigenetics is the study of heritable changes in gene expression (and hence traits) that cannot be explained by alterations in the DNA sequence. These changes instead involve chemical modifications to DNA and its associated histones. Some of these changes can be passed down through mitosis and some even through meiosis.
Exploration of this topic involves student presentations and active discussion of primary research articles and expands upon the participants’ previous coursework in genetics and chemistry. Jennifer Kennell.

BIOL 355 - Ecology and Evolution of Sexual Reproduction
1 unit(s)
Sex: “nothing in life is more important, more interesting - or troublesome.” This quotation from Olivia Judson, Ph.D., (a.k.a. Dr. Tatiana) is just one recent example of the long-standing fascination that ecologists and evolutionary biologists have had with sexual reproduction. This course begins with the question: What is sex? We then examine the current status of competing hypotheses for the evolution of sex, and then turn our attention to the myriad ecological and evolutionary consequences of sexual reproduction. We consider such questions as: Why are there only two sexes? Why do males and females look and behave differently? When is it advantageous to produce more sons than daughters (or vice versa)? When is it advantageous to be a hermaphrodite or to change sex? To address such questions in a biologically rigorous way, we need to draw on a wide range of theoretical work and empirical evidence from cellular and molecular biology, genetics, developmental biology, ecology, and evolutionary biology. Mark Schlessman.
Prerequisite(s): One unit of any 200-level Biology and One of the following: BIOL 208 , BIOL 226 , BIOL 241 , or Genetics (BIOL 238 , BIOL 244 or BIOL 248 ).

1 unit(s)
A consideration of physiological aspects of primary production, including the biogeochemical cycling of nutrients through plant systems. Topics will focus on the recent primary literature in the field.
Topic for 2018/19a: The Secret Lives of Plants. Plants are amazing survivalists. They have evolved myriad strategies to solve complex problems associated with terrestrial conquest and their stationary lifestyles. For instance, plants have become remarkable chemists capable of mounting full-scale biological warfare to fend off pathogen attacks, and master plumbers that carefully harness water power for transport and growth. This course examines how plants regulate their physiology through cellular and molecular adaptations, with emphasis on exploring open research questions. Topics may include environmental stress and defense responses, determinants of plant morphology, factors driving sexual reproduction, and agricultural themes ranging from identification of the genes underlying thousands of years of plant domestication to modern genetic engineering technologies that mark the next wave of the green revolution. Robert Augustine.
Prerequisite(s): Two units of any 200-level Biology.
Two 75-minute periods.
-
BIOL 360 - Animal Communication Semester Offered: Spring
1 unit(s)
All animals use communication to navigate interactions with other individuals. At its most basic animal communication is a feedback loop. Senders produce signals which travel through the environment and are picked up by a receiver. The reception of the signal changes the behavior of the receiver through either voluntary or involuntary neural and hormonal changes; this, in turn, changes the behavior of the sender. In this course we discuss (1) how animal signals are produced, transmitted, and received; (2) how information transfer has evolved and been optimized; (3) how animals use communication in mate attraction, social integration, and predator-prey interactions; and (4) the controversy surrounding the definition of communication. Animal communication is a highly interdisciplinary field and we explore the chemical and physical properties of signals, as well as the mathematical models, neural and hormonal control, and the ecological and evolutionary underpinnings of animal communication. This course also examines animal communication in the wild and thus some self-scheduled field work is required. Megan Gall.
Prerequisite(s): Two 200-level courses, with at least one of the following: BIOL 226 , BIOL 228 , BIOL 241 , or NEUR 201 .
One 3-hour period plus one 75-minute period.

BIOL 375 - Sensory Ecology
1 unit(s)
There are many behaviors that are critical to the survival and reproduction of animals including finding food, avoiding predators, attracting mates, and raising offspring. The ability to successfully engage in these behaviors is dependent on the ability of organisms to acquire and respond to information in their environment. In this course we will discuss the concept of information, the types of information available in the environment, the diversity of sensory systems animals have evolved to exploit that information, and how sensory information and processing influence behavior. Sensory ecology is a highly interdisciplinary field and we make use of mathematical, physical, chemical and biological principals. The class is divided among traditional lectures, student led discussions of the primary literature, and hands-on experiences with sensory ecology data collection and analysis. Megan Gall.

A close examination of the active research programs of several biologists who will visit Vassar to present their research to the Biology Department. By reading and discussing the primary literature and interacting with biologists at different stages of their careers, students develop a deep understanding of several current areas of biological research, and gain a better understanding of the scientific process. Students write a substantial paper focusing on one or more of the research areas discussed in class. Jodi Schwarz.
Prerequisite(s): Two units of any 200-level Biology.
Three 75-minute periods.
Not offered in 2018/19.

BIOL 381 - Topics in Ecosystem Ecology - Ecosystem Structure and Function Semester Offered: Fall
1 unit(s)
(Same as ENST 381 ) Topic for 2018/19a: Microbes and the Environment. In many ways, life on Earth could not exist without the activity of microbes. This course explores the functional roles that microbial organisms play in ecological systems. In addition, you learn how humans are using microbial organisms to maintain the health of the planet, as well as our own bodies. Finally, this course introduces you to some of the approaches that are used to better understand these microbial organisms and their functions. There is a strong emphasis on the primary literature. Myra Hughey.
Prerequisite(s): One course in Ecology (e.g., BIOL 241 or BIOL 356 at Vassar, or a course taken elsewhere).

BIOL 382 - Topics in Biology Semester Offered: Spring
1 unit(s)
A multi-level examination of advanced topics in biology, this course is an integrative evaluation of current topics in biology, particularly topics in animal or human biology. Emphasis is placed on current thinking and research and course material is drawn from the recent biological literature.
Topic for 2018/19b: Animal Migration. From zooplankton, to monarch butterfly, to humpback whale, migration is a widespread phenomenon among taxa that has fascinated humans for centuries. While migrating is vital for some organisms, it comes with many challenges to overcome. This course provides an introduction to the study of animal migration and explores fundamental questions (e.g., “why do animals migrate?”, “How do they migrate?”) by focusing on some major physiological, behavioral, and ecological components of migration. In particular, participants examine 1) how organisms balance the energetic needs of migration, 2) how organisms navigate their journey, 3) the mechanisms triggering migration, and 4) the contribution of migratory organisms to the functioning of ecosystems. Upon completion of the course, participants should be able to a) understand and explain major concepts and theories in animal migration, b) be familiar with key scientific literature in the field, c) critically evaluate research studies in the field and lead discussion, and d) appreciate the interdisciplinary aspect of the study of animal migration. Aude Lochet.
Prerequisite(s): Two units of 200-level Biology.
Two 75-minute periods.

BIOL 383 - Hormones and Behavior Semester Offered: Spring
1 unit(s)
This course is a comparative examination of hormones and behavior in animals. We take an evolutionary approach to this topic by emphasizing (1) the common selective pressures that act on all animals and the common hormonal and behavioral responses to these pressures, and (2) how extreme selective pressures drive the evolution of unique mechanisms in the field of behavioral endocrinology. Half lecture, half student-led discussions from the primary literature. Kelli Duncan.
Prerequisite(s): Two units of 200-level Biology or one unit of 200-level Biology and NEUR 201 .
Two 75-minute periods.

BIOL 384 - The Ecology of Evolution Semester Offered: Spring
1 unit(s)
This course explores the causes of adaptive radiation, possibly the most common syndrome of proliferation of taxa, through evidence that has accumulated since the formulation of the theory. The course reviews the ecological theory of adaptive radiation, the progress of adaptive radiation and phenotypic evolution, the origins of ecological diversity, divergent natural selection between environments, the ecological basis of speciation, and ecological opportunity. Primary literature is used to develop a richer understanding of the theory of adaptive radiation, whose origins trace back to Darwin (1859).
Prerequisite(s): Two units of 200-level Biology courses.
Two 75-minute periods.

BIOL 386 - Stem Cell Biology Semester Offered: Spring
1 unit(s)
Stem cell biology lies at the intersection of developmental/cell biology and medicine. This fast-moving field brings together many aspects of basic and applied biology and medicine including development, regeneration/repair, and cancer. This course covers a broad range of topics relevant to stem cell biology. We also consider the potential consequences and limitations of stem cell therapy, particularly the connection between stem cells and cancer. The format gives students both a broad background and the opportunity to apply critical thinking skills to recent data in this field. Since this is an upper level course, it assumes a basic understanding of genetics, biochemistry, and molecular biology, and so concepts drawing from these fields will not be covered in depth. This means that some students may find additional background reading necessary. Class material draws from primary literature and students participate in active discussion and presentations. Nancy Pokrywka.
Prerequisite(s): Two 200-level courses including one of the following: BIOL 218 , 238 , 244 , 248 , or 272 , and at least one semester of organic chemistry.
Two 75-minute periods.

BIOL 387 - Symbiotic Interactions
1 unit(s)
From the evolution of eukaryotic cells to the creation of entire ecosystems, endosymbiosis is a driving force in biology. This course provides an integrative perspective on host-symbiont interactions in diverse endosymbioses. We spend the first half of the semester examining the critical roles of symbiosis in ecology, evolution, and human systems. Then, we examine the underlying cellular and molecular processes that lead to an integrated host-symbiont partnership, for example mechanisms of host-symbiont recognition, regulation of nutrient exchange, and genomic interactions. Jodi Schwarz.
Prerequisite(s): Two 200-level Biology courses, including one of the following: BIOL 205 , BIOL 218 , BIOL 238 , BIOL 244 , BIOL 248 .
