Unit description Unit description
Symbiotic interactions underpin all biological systems. Symbiosis is defined as two (or more) species living together. Symbiotic interactions may be mutualistic, with both organisms benefiting from the partnership, or parasitic, where one of the partners is harmed. The association may be short-term or for the life of the organisms, with many symbiotic interactions essential for survival of the organisms. In this unit we explore diverse symbiotic partnerships spanning microbial, plant and animal taxa. We will investigate symbiosis in the context of biological roles and outcomes including health and disease of diverse taxa, co-evolution, and immunity. We will also address current issues of significance to symbiosis such as antibiotic resistance, emerging disease, ecosystem health and global change. Students who are interested in medical science, marine biology, conservation, evolution and ecology will enjoy this unit.

General Assessment Information

Assessment details

Details of assessments will be provided on iLearn and in class.

 

Assignment submission

All assignments will be digitally submitted through the appropriate Turnitin submission link on iLearn. An A3 printout of your poster is the only assessment that will be provided in hardcopy (and via Turnitin). All assessments need to be written in the students own words. 

 

Academic honesty

All assessments need to be written in the students own words. The penalties imposed by the University for plagiarism are serious and may include expulsion from the University. ANY evidence of plagiarism WILL be dealt with following University policy. Penalties for plagiarism will be imposed for each assessment and clearly defined in marking guides. Further penalties imposed by the Faculty disciplinary committee may range from a loss of all marks and awarding of a zero depending on the circumstances. 

 

Extensions, penalties and Disruptions to Studies

The deadlines for assignments are not negotiable. If an assignment is submitted late a penalty of -10% of the mark allocated for the assignment will be deducted per day that any work is submitted late (i.e. 5 days late = -50% of marks available).

If you experience a serious and unavoidable disruption to your studies and require an extension for an assessment please submit a Disruptions to Studies notification via ask.mq.edu.au with supporting documentation, and a Professional Authority Form completed by your health care professional. If you anticipate a potentially serious and unavoidable disruption (e.g. upcoming surgery) speak to the unit convenor early and apply for an extension before the due date.

Delivery and Resources

DELIVERY

BIOL364 is divided into themes and material presented in weekly lectures, lectorials and practical classes complement weekly themes. 

Lectures

Weekly lectures provide broad overviews to the topics that we explore each week. The lecture material complements material presented in practical classes and lectorials. To ensure that your performance and understanding of material on practicals and lectorials is optimal, we expect you to attend the lectures or listen to them before the lectorial and practical classes of the same week. 

Lectorials

Weekly lectorials delve deeper into the weekly unit themes. Lectorials comprise mini-lectures that are accompanied by small group tasks. Activities in the lectorial form the basis of content for your learning journal assessment. 

Practical classes

There are three major practical themes that will be covered in BIOL364. Practicals will run for several weeks. Some material required for the learning journal will be gathered in practical classes and major assessments are based on practical activities.

Dress for laboratory sessions

  • You must wear sturdy shoes that cover your feet.
  • You must wear a lab coat in every practical to protect your clothes.
  • You MUST bring your own lab coat to every class. We will no longer provide disposable lab coats as these are not environmentally friendly. 
  • Although the material that we will use has been rendered non-infectious good laboratory practice of wearing protective clothing when working with organisms that potentially cause disease is required. ALWAYS wash hands before leaving laboratory.
  • PLEASE NOTE
    • NO COAT = NO CLASS 
    • Inappropriate shoes = no laboratory access

RESOURCES

There are no required text books for BIOL364 Symbiosis in Health and Disease. we will provide references to many research papers that will assist with weekly unit themes.
