Introduction to Geometric Morphometrics

The course is entitled to teach the main concepts of shape analysis based on landmark coordinates and its multivariate procedures, and how they can be put into practice across any biological discipline in which the phenotype (form) and its variation are the principal sources of information.

Instructors: Dr. Jesús Marugán-Lobón, Dra Soledad De Esteban, Dr. Sergi Almécija

Course requirements: Graduate or Postgraduate in Biological Sciences, basic knowledge in Statistics and in personal computers. Personal laptop is recommended (Windows, Mac & Linux).

Language: English

Preliminary program:

- Introduction: what is geometric morphometrics. A brief history of the tool, and main differences with “traditional” morphometrics and “what can you do with GM”.

- Introduction: shape, size and biological morphology.

- Morphometric data: equipment, landmarks (2D and 3D), outlines and surfaces.

- Extracting shape: the Procrustes fit, shape spaces etc.

- Visualizing shapes and shape changes

- Looking at variation: PCA

- Distinguishing groups: CVA and discriminant analysis

-Testing the covariation: Predicting shape variability and testing shape variability: multivariate regression and Two-block Partial Least Squares

- Putting things together: combining tools to solve biological questions

Timetable: 10-13h and 15-18h
