Students gain knowledge of microbes and other biological agents used in criminal endeavours and an overview of the methods used to detect crimes involving biological agents and link them to individual perpetrators. Bioterrorism and agricultural bioterrorism are discussed. Prerequisite: 60% or higher in FRSC 2030H and a pass in one of FRSC 3000H, FRSC 3111H, BIOL 3080H, or BIOL 3250H.

This seminar-based course introduces students to the application of DNA profiling to forensics, medical genetics, and natural resource management (molecular ecology/conservation genetics). Prerequisite: 10.0 university credits including BIOL-FRSC 3700H.

Cross-listed: FRSC-4600H

Explores the processes shaping adaptive evolution and key aspects of organismal fitness, including life spans, sex, and gender. Seminars reinforce lecture material, but also cover additional topics. Two writing assignments provide opportunities for independent study. Prerequisite: A minimum overall average of 65% in completed BIOL, BIOC, and/or BIOM courses and 12.0 university credits including BIOL-ERSC 2260H, BIOL 2600H, and 1.0 BIOL credit at the 3000 level.

Epigenetics is the study of gene functions that are mitotically and/or meiotically heritable, but which do not entail a change in the sequence of DNA. This course reviews these epigenetics mechanisms and discusses how they influence cellular identity, development, predisposition to disease, tumorigenesis, and onset of neurological disorders. Prerequisite: A minimum overall average of 65% in completed BIOL, BIOC, and/or BIOM courses and 12.0 university credits including BIOL 3080H and 0.5 additional BIOL credit at the 3000 level.

Biological data has grown in size and complexity. Bioinformatics--the application of computer programming to the management and analysis of biological information--is necessary for storing, manipulating, and analyzing large datasets. A tutorial-based computer lab focusing on genome sequence data allows students to learn the basics of computer programming and bioinformatics. Prerequisite: FRSC-BIOL 2050H and one of FRSC-BIOL 3700H or BIOL 3600H.

Cross-listed: FRSC-4800H

Explores the interactions between the central nervous and endocrine systems, focusing on the hypothalamic-pituitary-adrenal axis. Examines the control of hormone release, including neurotransmitter modulation and steroid feedback during both homeostatic and stressor-induced states. Also, the interaction among stressors, behaviour, the endocrine system, and disease is considered. Prerequisite: 12.0 university credits including 65% or higher in one of BIOL-PSYC 3210H, BIOL 3840H, PSYC-BIOL 3220H, or PSYC 4225H.

Cross-listed: PSYC-4840H

A lab-based course focused on soil organisms and soil biodiversity; emphasis on the role of organisms in nutrient cycles and plant growth promotion using a hands-on approach to investigate key soil functions.
