Students will be briefly introduced to the phylum/class level characteristics of the major groups of invertebrate animals. The majority of the course will deal with the evolutionary history and phylogeny of invertebrates, invertebrate ecology, and the myriad solutions invertebrates have evolved to deal with the common problems of reproduction, feeding, osmoregulation, respiration, locomotion and developmental patterns. Prerequisites: 12 hours advanced biology, invertebrate zoology recommended. Credit 3.

BIO 571 Evolution. This course is concerned with modern concepts of the evolution of organisms. Extended reading and classroom discussion supplement the lecture treatment. Three one-hour lectures a week are scheduled. Prerequisite: introductory genetics. Credit 3.

BIO 575 Bacterial Physiology. A study of bacterial metabolism that will include fermentation, anaerobic respiration, bacterial photosynthesis and nitrogen fixation. This course will also discuss how bacteria sense their environment and adjust their metabolism accordingly. Three hours of lecture per week. Prerequisites: microbiology, genetics, and organic chemistry II or general physiology. Credit 3.

BIO 578 Virology. Virology. A study of viruses that infect plants, animals, and bacteria. Areas considered include chemical and structural properties of viruses, virus-host relations, and infection and growth phenomena, including interference and regulation. Also included are the roles of viruses as agents of disease and malignancy, and as gene vectors in natural settings, but also as tools in biotechnology and gene therapy. Three hours of lecture per week. Prerequisites: microbiology, genetics, and organic chemistry. Credit 3.

BIO 580 Advanced Ecology. Advanced Ecology. An advanced theoretical and practical study of biotic and abiotic ecosystem interactions encompassing the physiology of individuals, growth of populations including social and species interactions within populations, analysis of population composition and change, the distribution of communities, and the functioning of ecosystems.
