Geometric morphometrics Course in Berlin (5-9 March 2018)

carlo pecoraro, January 16, 2018

Dear all,

we have the last 5 spots left for the course "Geometric Morphometrics" which will be held in Berlin next March (5-9.03.2018)!!

OVERVIEW Geometric morphometrics has become a standard in biological research because it combines statistical rigour and ease of interpretation. Through geometric morphometrics, biological form is quantified, analysed and the results are expressed as easily interpretable and visually impactful shape changes. This course covers the main common practices of modern geometric morphometrics, including: acquiring data, analysing it, visualizing and interpreting the results.

FORMAT The course will be delivered over five days and will comprise both lectures and hands-on sessions. The lectures will cover both basic theoretical aspects and their practical implementation in research practice and software. During the hands-on sessions, the attendees will have the chance of both using example datasets and applying the knowledge acquired to their own data. The course will be focused mainly on 2D data and on easy-to-use software with graphical user interface to maximize the ability to understand concepts and apply them. However, some information on 3D data and on R implementations will be provided, as appropriate.

TARGET AUDIENCE This course is aimed at beginners and intermediate users. In other words, it is aimed at researchers who intend to use geometric morphometrics or who have started performing geometric morphometric analyses but feel they need a more structured background.

REQUIREMENTS Attendees should have a background in biology and a basic understanding of statistical

PROGRAM 5 March 2018- 09:30-17:30

Geometric morphometrics: overview and potential applications:

  • Traditional and geometric morphometrics
  • An overview of common analyses
  • Examples of geometric morphometrics applied to biological problems

From biological objects to numerical representation:

  • Overview of typical devices used to digitalise biological objects
