THIS COURSE WILL BE DELIVERED LIVE ONLINE
25 hours of online live lessons plus 5 hours of exercises to do between the live sessions
Live sessions will be recorded. Recordings will be made available to participants for a limited period of time. However, attendance to the live sessions is required.
Course overview
This course is for biologists dealing with the analysis of multiple molecular sequences at several levels: Populations, species, clades, communities. These biologists address questions relative to the evolutionary relationships among these sequences, as well as the evolutionary forces structuring biodiversity at different scales.
The objectives of the course are: (i) to know how to choose a strategy of molecular data analysis at the inter‐ or intraspecific levels, (ii) to be able to initiate a phylogenetic analysis starting from the files of molecular sequences until the interpretation of the results and the graphics.
The software used for this course will be centered on the R language for statistics. This will include the use of specialized packages particularly ape, phangorn, and adegenet.
Requirements
Graduate or postgraduate degree in any Biosciences discipline. Knowledge of multivariate statistics, phylogenetics and molecular evolution. User level of R.
All participants must have a personal computer (Windows, Macintosh), with webcam if possible, and a good internet connection.
