Geometric Morphometrics with Plants
This course offers a self-contained introduction to geometric morphometrics with a special focus on applications in plant evolution and development. Plant-specific aspects of data acquisition and evaluation are discussed, and the particular possibilities of geometric morphometrics in plants will be highlighted. Lectures about general morphological and developmental characteristics of plants are combined with an introduction to the concepts and techniques of shape analysis. Finally, advanced methods such as regression analyses, modularity tests and comparative phylogenetic analyses are presented. This theoretical basis is complemented by hands-on demonstrations of data collection and analyses.
The main focus of the course will be on landmark morphometrics, but a brief introduction and discussion of outline methods and semilandmarks is also provided.

If there are participants who already have collected their own data, they are encouraged to bring these data for conducting analyses and discussing results.

Graduate or postgraduate degree in any Sciences discipline, basic knowledge of statistics and personal computers. All participants must bring their own personal laptop (Windows, Macintosh, Linux) and field equipment (robust shoes!) for the sampling excursion. If you possess a camera, possibly with a macro lens, it might also be useful.
