For example, DNA and peptide sequences are now routinely analyzed using computational methods to determine both function and phylogenetic relationships. In addition, computational molecular dynamics simulations are used to study protein folding and why proteins sometimes misfold, leading to disease. And ecological simulations are used to better understand the effects of environmental damage. This interdisciplinary course will explore this broad area, examining the biology and the computational methods behind problems like these. The laboratory portion of the course will involve students working together in multidisciplinary groups to design algorithms to investigate these problems, as well as undertaking a self-designed capstone project at the end of the term. Prerequisites: Biology core and an introductory computer science course (CS 109-112), or consent.
Wetland Ecology (BIOL-310)
This course is a comprehensive study of wetland ecology, management, and policy. The main emphasis is on biological, chemical, and physical aspects of major wetland ecosystems found in North America. The course also deals with valuation, classification, and delineation of wetlands. A significant portion of the course focuses on local and regional wetland ecosystems: their history, ecology, and current status. Labs will be field-based explorations of the biology, chemistry, and ecology of these regional wetlands. Prerequisite: BIOL 202 or BIOL 230 or consent.
Herpetology (BIOL-312)

This course also will examine how viruses cause disease, how they are used in biotechnology, and their overall impact on society. The structure of the course will provide peer learning activities, class discussions of primary literature, and traditional lectures. The structure of the laboratory will allow students to develop and test their own hypotheses while learning bacteriophage and tissue culture techniques. Prerequisite: Biology core or consent.
Diversity of Microorganisms (BIOL-317)
This course examines the remarkable environmental, physiological, and metabolic diversity of prokaryotic and eukaryotic microorganisms (i.e., bacteria, protists, algae, & fungi). More specifically, diversity will be studied in terms of taxonomy and phylogeny, the ability of species to live in various environments, and the application of genomics in diversity. Emphasis will be placed on the reading of primary literature, and on using that information to make connections with class material. The structure of the course includes traditional lectures, class activities, and student presentations. Diversity of Microorganisms qualifies as a "biological diversity" course for the major and minor. Students may either take General Microbiology (BIOL 315) or Diversity of Microorganisms (BIOL 317) during their academic career, but not both courses. Prerequisite: Biology core or consent.
Plant Systematics (BIOL-320)
In Plant Systematics students learn how major groups of vascular plants are classified, named, and identified. We study approximately 50 plant families concentrating on native representatives (using living plant material whenever possible), learn how to use keys and floras to identify local species, and learn how to find information about plants in traditional and electronic sources. Understanding evolutionary relationships among the families studied is a central theme. This course provides important background for students planning to do fieldwork in ecology, plant-animal interactions, environmental education, and related subjects. Plant Systematics qualifies as "biological diversity" course for the major. Prerequisite: Biology core or consent.
Plant Ecology (BIOL-321)
In this course we will explore how plants interact with their environments and with other organisms, including man. We will begin at the individual level, learning how plants obtain resources from abiotic sources and through mutualistic interactions with bacteria and fungi. We will also consider how the theories of plant community ecology developed in the early 20th century and why they are pertinent today. Students will also have the opportunity to read and critique primary literature from leading journals in the field. Finally, we will develop several projects to be completed at the Denison Biological Reserve during the term for lab projects. These projects will be student-inspired and driven, with the hopes that they will contribute to our understanding of our immediate surroundings at Denison. Prerequisite: Biology core or consent.
Developmental Biology (BIOL-324)
Every multicellular organism begins its life as a single cell. Developmental biology is the study of the progression from this single cell to a complex, multicellular organism. Recently the powerful tools of molecular biology have linked the fields of embryology and genetics to reveal how cells, tissues, organs, and organisms develop. Especially striking is the conservation of molecules and mechanisms that underlie developmental processes in different organisms. This course provides an overview of the major features of early embryonic development in animals, and the mechanisms (molecular mechanism when known) that underlie them. We focus on two major aspects of developmental biology: (1) How is the basic body plan established? How does the basic organization of the embryo arise from the fertilized egg? What are the cellular mechanisms underlying morphogenesis and the appearance of pattered structures in the embryo? (2) How do parts become different in the embryo? Prerequisite: Biology core or consent.
Genetics (BIOL-325)
This course provides a detailed and up-to-date understanding of genetics, an appreciation of how genetics affects our lives everyday from the supermarket to the doctor's office, and a realization of the applications of genetics to virtually every discipline of biology. We focus on three major areas of genetics: (1) Molecular genetics: Thinking about genetics on the DNA level - everything from DNA sequencing to mutagen testing. (2) Mendelian genetics: Thinking about genetics on the gene level-everything from inheritance to recombinational mapping. (3) The application of both molecular and Mendelian genetics to study biological processes. We start by seeing how genetic techniques can be used to dissect almost any biological process and end up answering questions such as: How does genetic disease screening work? How are genes cloned from complex organisms such as mice or even humans? How does gene therapy work? In the laboratory we carry out both molecular experiments and classical genetic experiments. Prerequisite: Biology core or consent.
Plant Evolution and Reproduction (BIOL-326)
In this course we will explore the evolutionary relationships and histories among the major groups of plants, both terrestrial and aquatic. We will pay particular attention to their modes of reproduction and the structures that facilitate gamete production and dispersal. We will learn how plant physiology and developmental mechanisms have allowed taxa to persist or make major transitions among different environments over time. Class reading material will consist of the primary literature and will be presented by students every week. For the laboratory component we will have one overnight trip to Hocking Hills on a weekend in September to examine and identify plants in their natural habitat, as well as shorter trips to Blackhand Gorge and the Dawes Arboretum. We will also plan together and complete a semester-long project on the effects of environment on the development of reproductive structures in the model plant, Arabidopsis thaliana. Plant Evolution and Reproduction qualifies as a "biological diversity" course for the major. Prerequisite: Biology core or consent.
Biology of Insects (BIOL-327)
In this course we will explore the world of insects and their interactions with other species. Our central focus will be to survey insect diversity and explore how various orders, families, and species are adapted through evolution to their specific environment. But we will also use that diversity as a lens through which we will examine major concepts in biology. Topics of discussion will include the following: plant-insect coevolution, mating systems, anti-predator defenses, eusocial behavior, parasitism, disease transmittance, insect conservation, and control of agricultural pests. Laboratory will involve collecting insects in the field (including at times outside of class hours), identification, and preparing a collection. Biology of Insects qualifies as a "biological diversity" course for the major. Prerequisite: Biology core or consent.

This course will examine the adaptive significance of physiological traits at the molecular, tissue, organ and whole organism level in humans and a variety of non-human animals. Students will participate in course labs and design their own physiology experiments. Prerequisite: Biology core or consent.
Invertebrate Zoology (BIOL-336)
Invertebrates constitute more than 97% of all animal species on Earth. They are an incredibly diverse group of organisms that have been classified into more than 30 phyla, each with unique anatomical, physiological, and behavioral traits. In this course, we explore the evolutionary history of invertebrates, and how these traits evolved as adaptions for specific terrestrial, aquatic, and/or marine environments. We examine certain taxa in greater detail to address major concepts in biology; this is done in conjunction with article discussions and laboratory exercises that involve a variety of approaches in both the lab and field. Students have the opportunity to complete at least one self-designed experiment by the end of the semester. Invertebrate Zoology qualifies as a "biological diversity" course for the major. Prerequisites: Biology core or consent.
Animal Behavior (BIOL-340)

The course will start with an exploration of neurons and signaling within and among cells. We will then examine some sensory and motor systems. The last portion of the course will examine the whole animal in a neurophysiological context. The classroom portion of the course consists of lectures, discussion of the text and of research articles, problem sets, analysis of case studies, and other activities. The laboratory component will involve a mixture of behavioral, anatomical, and physiological studies on vertebrate and invertebrate animals, electronic modeling of nerve circuits, and computer simulations of nerve activity. The labs are designed to introduce students to some fundamental neurophysiological techniques and to a variety of study organisms, and to strengthen experimental design and analysis skills. Prerequisite: Biology core or consent.
Genomics (BIOL-350)
Genomics is the study of genomes, the entire collection of genetic information found in a specific organism. This field of study attempts to understand how all of the genes in a given genome cooperatively function to orchestrate the biological activities within the organism. The genomic DNA sequences of thousands of species have been determined, including humans, providing a wealth of information about the genetic composition and evolutionary relatedness of species. This course will introduce students to the fundamental concepts in genomics, including how genome sequences are assembled, how potential genes within the genome are identified and characterized, how genomes are organized and regulated, and how genomes evolve. Contemporary papers from the field of genomics will be discussed to complement the concepts addressed in class. The laboratory component of this course will be computer-based, utilizing various online databases and "bioinformatic" programs to carry out a series of projects on genome assembly and compositional analysis as well as "wet-lab" experiments to explore genome regulation. This course satisfies the oral communication requirement. Prerequisites: Biology core or consent.
