An introduction to organismal biology and ecology primarily for those who intend to continue in biology, but also open to interested students not majoring in science. Topics include population genetics, evolution, vertebrate embryology and anatomy, and animal phylogeny, taxonomy, and ecology. Biology 102 may be taken before Biology 101, if necessary.

A study of the basic life functions of animals. The focus of the course is the relationship between the physical and chemical functions of various organs and organ systems to overall homeostasis. Specific examples are drawn predominantly from human physiological systems. Anatomy is not emphasized.

Prerequisites: Biology 101-102, Chemistry 101-102.

Chemistry 201-202 recommended.

This course will examine the following areas of evolution: population and quantitative genetics, natural and sexual selection, adaptation, speciation, and the major themes in phylogenetic evolution. Basic theory as well as empirical evidence for evolutionary processes that occur in both natural and computer-modeled populations will be explored. Prerequisites: (BIO 201) or permission of the instructor.

The course surveys the natural history, evolution, and ecology of the vertebrates native to the Hudson Valley region. Lab sessions are used for identification, taxonomy, and study techniques, with as much work as possible done in the field. Occasionally, evening or weekend classes are required.

Prerequisites: Biology 101 and 102, Upper College standing, permission of the instructor; Biology 305 recommended.

2 credits Juniors and seniors concentrating in biology are strongly urged to take this two-credit course. Each senior enrolled in the course presents his or her research in progress, or significant material from the current literature at one session. Each junior presents an interesting paper of his or her choice from the literature. The purpose of the seminar is to encourage juniors to become familiar with both the biological literature and research undertaken in the program.

A consideration of biological inheritance in prokaryotes (bacteria) and their viruses (bacteriophage). Topics include the genetics of mutagenesis, repair and recombination, transformation, plasmids, conjugation, intemperate phages, temperate phages, transduction, gene regulation, restriction endonucleases, and gene splicing. Lectures will alternate with student presentations of classic papers in chronological order. Laboratory work will provide practical experience in the topics covered.

Prerequisites: Biology 201and 303, and Chemistry 201-202.

This course explores molecular aspects of cellular function at an advanced level. Topics include the structure and function of the cell membrane, cytoskeleton, and cell organelles, and techniques used in the study of modern cell biology. Emphasis is placed on current literature in the field.

Prerequisite: Biology 201, Chemistry 201-202.
