Questions

3. Introduction

4. Introduction
Symbiotic relationship between Plants and Mycorrhizal Fungi
Plants give carbon derived form photosynthesis
Mycorrhizal Fungi share valuable nutrients

5. Introduction

6. Introduction

7. Problem Why should we care?
Agriculture: We are running out of phosphorus.
Plant and Mycorrhizal Fungi networks is a simple solution.

8. Problem How do you achieve optimal symbiosis?
How do you to detect communities within the network?
What are the driving factors for community development?

9. Challenges
It is time consuming and expensive to sample DNA of plants and fungi
It is hard to determine what is a community
It is hard to say what exactly facilitates growth of communities

10. Background Community level network analysis missing
Trait-based partner selection
Host identity a driving factor
Functional diversity in agricultural systems

11. Solution What is the best way to discover communities?
Use predictive analysis for community detection
Community detection vs. Clustering

12. Conclusion Foundation of project Problem & challenges
Background studies
My approach
