2014-2015 Academic Year

Fall 2014

BIOL 325 Plant Physiology w/Lab
A study of plant structure and function, with emphasis on the flowering plants. Includes plant cells and organelles, mineral nutrition, translocation processes, and hormonal regulation of growth, development, and reproduction. Biochemical and environmental aspects of photosynthesis are emphasized. Six hours classroom/laboratory a week. Prerequisites: two Biology courses numbered between 120 and 129. This course will fulfill the WR graduation requirement.

CHEM 343 Metabolism
Cross-listed with BIOL 343-01.

BIOL 129 Changing Ocean Ecosystem W/Lab
An introduction to the biology of marine communities, including salt marshes and mangroves, intertidal zones, reefs, and deep-sea vents, among others. For each community, the physical characteristics of the environment as well as the physiological adaptations of the resident species will be examined. We will also focus on how marine communities are changing in response to anthropogenic stresses in light of concepts such as diversity indexes, keystone species, and disturbance theory. Selected readings from the primary literature and the popular press are required. Laboratory projects will emphasize experimental design and hypothesis testing. Three hours classroom and three hours laboratory a week. This course fulfills either the DIV III lab science distribution requirement or QR graduation requirement.
