Emphasis is placed on the theoretical underpinnings of modern evolutionary biology (mutation, selection, migration, & drift) that produce evolutionary change. Additionally, students are introduced to a variety of analytical and technical skills used for studying evolution. Topics covered include population genetics, the theory of evolution by natural selection, concepts of fitness and adaptation, genetic and developmental bases of evolutionary change, modes of speciation, molecular evolution, principles of systematic biology, paleontology and macroevolutionary trends in evolution, the origins of life, and extinction, among others. We hope that exposure to the tremendous diversity within this discipline will illustrate why evolution is viewed as the central theme unifying all of biology.

This course focuses on understanding the physical, chemical, and biological properties of freshwater lakes, streams and wetlands as well as estuarine systems and salt marshes.   Students will learn how concepts, ecological theory and methods can be integrated to address applied problems in aquatic and coastal zone ecology.  This course assumes a basic background in biology, chemistry, math and physics.  The course will allow you to become familiar with the scope of aquatic and coastal zone ecology and to master its basic facts, principles, and concepts. The approach will include a mix of theory (including a variety of mathematical, verbal, and graphical models of important ecological processes), and field and lab techniques.  Students  will also learn about how the science is done by looking at examples of research in course readings, examples in lecture, guest lecturers and by reading published research.  A key goal of the course is to develop a conceptual framework that may be used to pose and answer relevant questions in the discipline and to develop an appreciation for the special challenges involved in aquatic and coastal zone ecological studies. The course will also introduce to management of these resources.  Management is complex and integrates multidisciplinary natural and social sciences.  It requires exploration and knowledge about the relationships between habitats, applied ecology, climate, hydrology, watersheds and all types of human activities that affect aquatic ecosystems (e.g. urban development, coastal development, tourism, fisheries, protected areas, aquaculture and agriculture).   Prerequisites:  BIO1027, BIO1028, BIO2010, BIO2018 or consent of instructor.  Three hours lecture and one laboratory/field period per week.
