• CAS BI 486: Biological Design for Sustainable Development (EBE)
  Study of biological constraints on the problem of human society's relationship with the ecosystems, terrestrial and marine, that sustain it. Case studies combining natural history, ecological theory, dynamical modeling, and experimental design in the search for workable solutions.
• CAS BI 491: Undergraduate Research in Biology IV
  Research in biological science for students at the senior level. Students design and implement a research project with a faculty member. A minimum of 12 hours per week in lab or field work, not including preparation or evaluation time. Research topic must be defined at the time of registration. Course grade is determined by laboratory performance and written report.
• CAS BI 492: Undergraduate Research in Biology IV
  Research in biological science for students at the senior level. Students design and implement a research project with a faculty member. A minimum of 12 hours per week in lab or field work, not including preparation or evaluation time. Research topic must be defined at the time of registration. Course grade is to be determined by laboratory performance and written report.
• CAS BI 495: Seminar in Research
  For research students to consider issues of ethics in science and help develop methods in data gathering, analysis, and presentation of their own research activities. Students analyze research papers, grant proposals, and their own work; a written paper and oral presentation are required.
• CAS BI 502: Topics in the Theory of Biological Networks
  Examines principles for the control of biological systems, focusing on the relationship between network geometry and function. Examples include transcription networks, ecosystems, and neural networks. Assignments include student presentations on primary literature, and the option of computational modeling.
• CAS BI 503: Symbiosis (EBE)
  Explores a dominant survival mechanism in the Earth's history. Emphasizes partner integration in cell evolution, metabolic basis of the associations, the ubiquity of such association in all ecosystems, and the study of key symbolic systems on Earth today, including coral reefs, mycorrhizae/plants, and lichens. Three hours lecture.
• CAS BI 506: Phenotypic Plasticity
  Explores the flexible phenotype as a product of development and target of natural selection, and addresses the role of plasticity in ecological interactions and evolutionary diversity. Topics: plasticity genetics, evolution, developmental mechanisms, functional ecology, learning, and diversification of life. Three hours lecture, one hour discussion.
• CAS BI 508: Behavioral Ecology (EBE)
  Examines the adaptive significance of behavior in an ecological context. Topics include the evolution of social behavior, mating systems, sexual selection, alternative reproductive behaviors, life history strategies, optimal foraging, territoriality, cooperation and conflict, host-parasite co-evolution, the ecology of communication, and comparative analyses.
• CAS BI 512: Mammalian Ecology (EBE)
  Evaluation of ecological, behavioral, and physiological adaptations of mammals, with emphasis on social behavior, reproductive ecology, feeding ecology, energetics, evolution, and conservation biology. Research papers. Oral presentations. Weekend field trip required September 21?23, 2007. Three hours lecture, three hours lab.
• CAS BI 513: Genetics Laboratory
  Genetic techniques such as mutant selection and screening, complementation, mapping, recombinant DNA, and chemical genetic screening are taught using the genetic model systems Escherichia coli, Saccharomyces cerevisiae, and Arabidopsis thaliana. Short-term and long-term projects in which students formulate and test hypotheses.
• CAS BI 515: Population Genetics (EBE)
  Examines the interaction of basic evolutionary processes, including mutation, natural selection, genetic drift, inbreeding, and recombination, in determining the genetic composition of populations. Covers both classic models of the modern evolutionary synthesis and newer approaches based on coalescent theory.
• CAS BI 519: Theoretical Evolutionary Ecology
  Familiarizes students with the theory of evolutionary ecology. Students gain enough background to read theoretical evolutionary ecology literature, do simple modeling, and move on to more complex theory. Students gain experience through homework assignments and computer labs.
• CAS BI 520: Sensory Neurobiology (PER/Neuro)
  Fundamental properties of sensory systems including anatomy and function. Oriented toward contemporary research with particular focus on molecular and cellular mechanisms of transduction, neural coding of information, and sensory perception. Major senses including the visual, somatosensory, auditory, olfactory and gustatory systems.
• CAS BI 527: Biochemistry Laboratory I, II
  Emphasizes the purification and characterization of proteins and DNA. Development and use of modern instrumentation and techniques. Same as CH527 and laboratory portion of CAS BI/CH421. Required for BMB students enrolled concurrently in GMS BI 555. Four hours lab, one hour discussion.
