Courses

Experimental Designs in Biology (BLY 304)

Biological has moved from an historically qualitative discipline to one that is quantitative. Thus, it has become increasingly important for Biology students to develop strong analytical skills. Experimental designs in Biology is intended to provide students with the basic skills experimental design and statistical methodology needed in modern biological research. Additionally, student will learn basic statistical software (e.g., Minitab, Ecosim, Resampling Procedures, PAST).

General Entomology (BLY 354)

Emphasis is placed on insect form, function, classification, and evolution, as well as their impact on human societies. In addition, the student will be expected to make an insect collection of at least 75 families with at least 75 specimens.

Freshwater Ecology (BLY 426/526)

With emphasis placed on lakes, streams, ponds, and wetlands, this course will focus on four major aspects of freshwater ecology: i) physical and chemical properties of water; ii) ecology and taxonomy of aquatic organisms; iii) links between different freshwater systems; and iv) human influence on freshwater ecosystems (eutrophication, acidification, hydroelectric projects, introduced species etc.). In addition, students will be required to submit a collection of local freshwater invertebrates and fish.

Biometry (BLY 520)

The aim of Biometry is to provide a solid foundation in some of the applications of basic statistical techniques used in modern biological research. In addition the student will become familiar with several commonly used statistical software packages. Topics covered in this course were selected because they are commonly encountered in the practice of biology and will provide a basis for learning other techniques.
