Biology courses deal with the science of living organisms in their various forms. The curriculum emphasizes the integration of all levels from molecular to ecological, with evolution as a unifying theme, and requires all seniors to complete a research thesis. The department serves students who expect to work in a biological field or related profession such as medicine, as well as those who elect biology as part of a general education (see www.whitman.edu/biology).
A student who enters Whitman without any prior college-level preparation in biology will have to complete 50 credits, including courses in chemistry, mathematics, and biology, to fulfill the requirements for the biology major.
Distribution: Courses completed in biology apply to the science and quantitative analysis (selected courses) distribution areas.
Learning Goals: Upon graduation, a student will be able to:
- Major-Specific Areas of Knowledge
- Master foundational material that spans the diverse biological sub-disciplines, from molecular to ecological. Develop an integrative perspective that draws connections between sub-disciplines.
- Accessing Academic Community/Resources
- Develop science literacy.
- Develop the ability to communicate science orally and in writing.
- Critical Thinking
- Apply the scientific method to think critically about the world.
- Research Experience
- Engage in the practice of biology via research-based thesis.
The Biology major: A minimum of 33 credits in biology, including Biology 111, 112, 205, 206; four credits from each of the three categories of upper-level courses (Molecular/Cell Biology, Organismal Biology, Ecology/Evolution); 489; 490 or 498; 499; and additional courses in biology and/or BBMB courses numbered 200 or above to earn a minimum total of 33 credits in biology and/or BBMB.

Three lectures and one three-hour lab per week. Applies to the Ecology/Evolution major requirement. Prerequisites: Biology 111 and 205. Biology 112 and 277 or 215 are recommended. Lab fee: maximum $20.
353 Plant Physiology
4, x Altermann
Plant physiology is the study of how plants function, internally as well as in relation to their environment. We will investigate how plants use light, water, and minerals to grow and reproduce, at both whole-plant and molecular levels. How do plants cope with stressful environments? How do they adapt to strange or extreme environments? How can a better understanding of plant physiology improve our ability to deal with social issues such as famine, malnutrition, and the conservation of biodiversity? Through lecture, written exercises, discussions of research articles, and laboratories, we will consider these and other key aspects of plant physiology. Three lectures and one three-hour lab per week. Applies to the Organismal major requirement. Prerequisites: Biology 111 and 112. Lab fee: maximum $20.

The topic and course credit will be designated prior to registration for the semester in which a special topic is offered. Any current offerings follow.
471 ST: Thermal Physiology
4, x Lease
This course will use a comparative approach to introduce students to animal thermal physiology and ecology. It will do so via investigation of the thermal properties of different ecosystems and the challenges that they present to animals living in them. We will examine the fundamental principles of physiological systems by examining features that are conserved among a wide diversity of animals, as well as physiological and behavioral strategies that are unique to particular animals (both thermoregulators and thermoconformers). We will additionally discuss thermal physiology with respect to current projections of global climate change. Research techniques will be highlighted during lectures and lab, and the course itself will consist of content based lectures, discussion of the primary literature, class investigation of particular environmental conditions and animal responses to these conditions, and hands-on research studies. Prerequisites: Biology 111 and 112. Distribution area: Science with a lab. May be applied toward the Organismal Biology category.
472A ST: Symbiosis
x, 4 Altermann
From the origin of mitochondria to the phenomenon of zombie ants, symbiotic interactions are ubiquitous and important components of ecological communities. This course is a survey of topics in symbiotic biology involving multiple scales of interaction spanning the level of molecules to the level of ecosystems; all major taxonomic groups are a crucial part of the course. Topics will include the evolutionary history of the eukaryotic cell, horizontal gene transfer, acquisition of metabolic pathways, development of novel symbiotic structures, the mechanism of the transfer of nutrients, regulation of symbioses, and partnership specificity. The course includes lectures, discussions of the primary literature, and a laboratory in which students will design and carry out their own manipulative experiments on symbiotic partnerships. Three lectures and one three-hour lab per week. May be applied toward the Ecology/Evolution major requirement. Prerequisites: Biology 111 and 112. Distribution area: Science with a lab.
472B ST: Parasitology
x, 2 Crook
Parasites are the arguably the most highly evolved organisms on the planet. They are engaged in a constant, high stakes evolutionary arms race with their hosts that has resulted in them colonizing every known species, from single celled amoeba to mammals. This arms race has produced a hugely diverse panoply of parasite types, life strategies and parasite-host interactions that are not only fascinating scientific curiosities, but are also serious challenges to the health and well-being of humans across the planet. This seminar course will take you on a journey through the world of parasites from a parasite's perspective. Classes will be a mix of lecture, discussion of the primary literature and student presentations. May be applied toward the Ecology/Evolution major requirement. Prerequisites: Biology 111 and 112. Distribution area: science.
472C ST: Physiological Ecology of Environmental Extremes
x, 2 Lease
This course will use a comparative physiological approach to examine animal adaptation to ecological extremes (e.g., high temperature, low temperature, high aridity, high humidity, high altitude, high osmolality, high pressure...). It will do so via investigation of short term (acute) and long term (chronic, plus evolutionary) physiological responses to such conditions. Core physiological concepts will be introduced, and used as a framework to investigate the diversity of physiological "solutions to life" that animals have acquired to environmental extremes. Research techniques will be highlighted, and the course itself will consist of content based lectures, discussion of the primary literature, and investigation of particular environmental conditions and animal responses to these conditions. Prerequisites: Biology 111 and 112. Distribution area: science.
481, 482 Special Projects
1-3, 1-3 Staff
Selected topics of an experimental or descriptive nature, arranged with individual students who are prepared to undertake semi-independent work. The students will consult with the faculty member most closely associated with the area of interest to determine if the topic is suitable and can be successfully accomplished with the available material and library facilities. This consultation should take place in the semester preceding the anticipated research project. Prerequisite: consent of the supervising instructor.
