Ecology of microbial communities (human/environmental settings), what they do, and how we study them, focusing on microbial diversity, rare biosphere and microbial dark matter with their links to ecosystem functions.Note: This paper includes additional non-streamed lab time that does not appear in the timetable. Please contact the department for further details.
Microorganisms control the environmental processes that sustain the Earth's biosphere. From soils to the human gut, microbial communities are emerging as central drivers of the living world. This paper will introduce you to the many roles of microbes in everyday life and cover topics on microbial diversity, and how it can be studied, as well as how this diversity affects ecosystem functions. We will cover a broad range of ecosystems (from marine to human associated) and provide you with in-depth knowledge of the microbial makeup of the world.

- Paper Structure
25 lectures and 8 laboratory sessions
Lectures address the following issues:
- A framework for understanding microbial diversity
- Understanding microbial functional potential
- Spatial and temporal variance in microbial communities
- Environmental stressor-resistance and resilience in microbial ecology
You will gain valuable skills required for working with BIG data; these include quality control, processing of amplicon data, data manipulation with PhylsoSeq and statistical analysis and metadata manipulation in R.
This course is for students interested in ecology of microorganisms in natural environments, and the tools used to study them.
These concepts are further explored in laboratory exercises:
- Week 1. Wet lab: Laboratory based experimental work will include sampling, nucleic acid extraction, quality assessment and PCR amplification. Computational analysis of experimental work will be covered in weeks 2 – 4 and will be held in the computer labs (CAL).
- Week 2. Computer lab: Handling and quality controlling amplicon data
- Week 3. Computer lab: Basic data manipulation and visualization in PhyloSeq
- Week 4. Computer lab: Statistical analysis, correlation, and metadata manipulation in R
- Group oral presentation (10%)
- Final written report (25%)
- Laboratory notebook/R markdown files (10%)
- Final written exam (55%)
- Teaching Arrangements
- There are two lectures per week. There are two laboratory sessions per week in week 5-8 of the second semester, with flexible times for students taking lectures with overlap. Students may leave the lab for other commitments such as lectures and are able to plan their experiments to fit in with these commitments.
- There is no required text for this course but you will be directed to relevant scientific papers during lectures.
