BSCI 106 : PRINCIPLES OF BIOLOGY II Ecology and Evolution Dr. Marcia Shofner, Spring 2010 MWF 1-1:50, Tydings 0130 Text: Biological Science, 3rd Ed. Scott Freeman. 2008. Pearson Education, Inc. ISBN: 0-13-140941-7 Lab Manual: Biological Sciences 106 Lab Manual. Jeffrey S. Jensen. 2008. HaydenMcNeil ISBN: 978-0-7380-3049-4 "No one with an unbiased mind can study any living creature, however humble, without being struck with enthusiasm at its marvelous structure and properties" -- Charles Darwin COURSE DESCRIPTION: BSCI 106 introduces you to topics within the broad fields of Ecology and Evolution. One aspect of this course will be to examine these concepts within the framework of the Chesapeake Bay, a valued natural resource close to home. A second goal is to gain an understanding and appreciation of sustainability practices and research. We include sustainability in the course to help identify and explore connections between basic biological concepts and global practices that impact all life on earth. The course will highlight studies that seek biologically-based and sustainable solutions to challenges that we now face in our society and among all living organisms.
