NBIB25002U Introduction to Ecological Modelling: From Microbial to Ecosystem Dynamics

BSc Programme in Biology

Content

This course provides an overview of and an introduction to ecological modelling. The course emphasizes on computational simulations of two contrasting biological levels: the ecosystem and the microbial community. We model their responses to environmental and climate changes. We teach basic concepts in modelling, the structures of two widely used ecological models (i.e., LPJ-GUESS and DEMENT), and how models, together with observational data, can be used to understand ecological systems better. We apply and test ecological models to understand process interactions and system responses. The teachers have extensive experience with these models, and you will work closely with the teachers during the practical sessions.

Topics include:

  • Ecosystem biogeochemical cycles
  • Vegetation dynamics
  • Microbial processes: traits and community structure
  • Model-data integration
  • Model sensitivity testing, evaluation and prediction
  • Modelling plant-plant and microbial community competition
Learning Outcome

After completion of the course, you will have acquired the following:

 

Knowledge:

  • Explain how different ecosystem processes and ecological interactions are represented in models.
  • Describe the basic concepts of model structure, inputs and outputs, model sensitivity and uncertainty testing.
  • Identify diverse methods for integrating observational data with models to investigate ecological processes.

 

Skills:

  • Compile model codes and run simulations using varied inputs
  • Conduct sensitivity and uncertainty testing to assess the relative importance of different inputs and parameters
  • Assess model performance by comparing simulations with observational data
  • Apply AI tools to enhance efficiency and accuracy in modelling-related tasks.

 

Competences:

  • Independently execute model simulations to quantify process and organismal interactions and evaluate the relative importance of different processes/parameters
  • Reflect on complex ecological questions by applying model simulation experiments
  • Critically evaluate and interpret model outputs, draw conclusions about studied ecological processes, and assess their implications.

We expect students to have passed basic bachelor-level courses in mathematics, equivalent to NMAA04011U Matematik/Statistik (MatStat) (Mathematics/​Statistics). No previous experience with modelling software is expected.
It is recommended that students have taken courses equivalent to Almen Økologi (General Ecology) or Almen mikrobiologi (General Microbiology) to attend this course.

For Biology students who have passed all first-year courses and half of the second-year courses by the start of the course (corresponding to a total of 90 ECTS points) of their curriculum should be well prepared to master the course material.
Lectures, computer practicals, group discussions, peer feedback and student presentations of model outputs
Students must bring their own laptops

Peer feedback (Students give each other feedback)
Credit
7,5 ECTS
Type of assessment
Oral exam on basis of previous submission, 20 minutes
Type of assessment details
Written group report during the practical session of the course, followed by an individual oral examination, 20 minutes.
The written report is prepared in groups during the course and presents modelling steps and results. The written report must be handed in in groups before the exam week.
After handing in the report, there will be one week to prepare for the oral exam. At the oral exam, the student will present the handed-in group report individually. It will focus on explaining the model steps, outputs, sensitivity testing, and model uncertainties.
Exam registration requirements

Students must actively participate in at least 3 out of 4 oral presentations during practical sessions and submit their written report.

Aid
Only certain aids allowed (see description below)

Reports: All aids are allowed.

Large Language Models (LLM)/large multimodal models (LMM), e.g., ChatGPT and GPT-4, are allowed to assist in making figures, interpreting model code, and writing codes. 

Marking scale
7-point grading scale
Censorship form
No external censorship
One internal examiner
Re-exam

Same as the ordinary exam.

If the report has not been approved, a new report must be handed in no later than three weeks before the re-exam, all aids are allowed. 

If the student hasn't attented in all the required oral presentations, the student must make a new oral presentation, no later than three weeks before the re-exam, the detalis are agreed with the course coordinator. 

 

Criteria for exam assesment

In order to obtain the grade 12, the student should convincingly demonstrate their understanding of two models and show knowledge, skills and competencies described under Learning Outcome.
