Department of Biological Sciences


Welcome to the Department of Biological Sciences

Biological sciences delve into the world of living organisms — from microbes, to human beings, to entire ecosystems. It is the science of life on, under and above earth.


The Department of Biological Sciences provides you with hands-on learning, moving you beyond textbooks and lectures to engaging research projects. Biology is a research-intensive science that can lead to a wide range of study areas, like environmental work, medicine, microbiology or agriculture. Exploring the nature of life leads biologists out into the world where they study how organisms interact with their environment, how they function and how they evolved over time.

Important Information for Registering for Fall Courses

*****PLEASE READ​*****

We know you are thinking ahead to 2021/22 and registering for your fall courses.  While some courses like Biol 1010 and 1020 are offered in both the fall and spring semester, many other required classes are only offered once a year.  As such it is important to plan ahead and take them in the appropriate year when they are offered to avoid downstream problems with pre-requisites for third and fourth year classes.  Below is a list of the required classes for Biology major and when they are typically* offered.  It does not include the list courses in third year where you have options.

First Year

  • Biol 1010 Cellular Basis of Life fall (2 sections) and spring semester
  • Biol 1020 Diversity of Life fall and spring semester

 Second Year

  • Biol 2000 Principles of Genetics fall and spring semester
  • Biol 2150 Biostatistics fall semester only
  • Biol 2200 Principles of Ecology fall semester only
  • Biol 2300 Cell Biology spring semester only

 Third Year

  • Biol 3300 Evolution spring semester only

 Fourth Year

*based on the current schedule for 21/22 and tentative timetable for 22/23 

Study into the effects of medical cannabis cultivars on COVID-19 virus advances to clinical study stage

After receiving international attention, two University of Lethbridge studies that explored the potential for certain cannabis extracts to be used as additional therapies to combat COVID-19 have undergone peer review and have now been published in Aging, a top, open-access, bio-medical journal.

The studies by Drs. Igor and Olga Kovalchuk, both U of L biology professors, were conducted in the early days of the COVID-19 pandemic. They investigated the ways specific Cannabis sativa extracts could be used as adjunct treatments for COVID-19. With the need to get relevant research out as quickly as possible to help combat the pandemic, their findings were originally released as preprints. The studies, In search of preventive strategies and Fighting the storm  found that certain cannabis extracts, including those high in cannabidiol (CBD), help prevent the SARS-CoV-2 virus from entering cells and help ward off cytokine storms that can lead to acute respiratory distress syndrome. High-CBD cannabis extracts are not psychoactive.

Master of Science in Biological Sciences (Sustainable Agriculture)

Agriculture has become one of the most important applications of scientific knowledge. The challenge of feeding a planet while sustaining the health of the environment and agricultural workers requires expertise in biological science.

The University of Lethbridge, with financial support from the McCain Foundation, is funding research for students in a Master of Science program majoring in Biological Sciences (focusing on Sustainable Agriculture). Successful applicants will have a BSc degree, or equivalent, and meet all the admission requirements of the School of Graduate Studies. All qualified applicants will be considered for one of six McCain Biology Sustainable Agriculture MSc Awards valued at $20,000/year for two years.  Additional financial support may be available. Thesis research projects related to water, plants, climate change, natural products, microbiology, toxicology, and genetics are central to Sustainable Agriculture and can be supervised by professors with relevant expertise in the Department of Biological Sciences.
