  • BIOL 244 Biostatistics 3 credits

    An introduction to statistical techniques commonly used in Biology. The course will use examples from primary literature to examine the different ways that biological data are organized and analyzed. Emphasis will be placed on how to choose the appropriate statistical techniques in different circumstances and how to use statistical software to carry out tests.

  • BIOL 363 Seminar: Ecomechanics 6 credits

    All organisms, from Common loons to Redwood trees to Basking sharks spend much of their lives bumping up against forces associated with the non-biological world. The manner in which ecological challenges are solved (e.g., moving around vs. staying put, finding food, avoiding predators) is often related to an individual’s biomechanical design. This class will challenge students to view their physical surroundings from the perspective of an organism. How do mussels feed in a fast stream vs. stagnant pond? Why do healthy trees uproot rather than break in half? How can a sea urchin with no eyes “see”? We will use primary scientific literature to examine the physical principles that underlie fundamental ecological processes.
