8th to 12th January, 2015 - Bayreuth, Germany

Workshop 2  (January 8)   

Free your mind: Model comparison and model testing in historical biogeography
with the R package 'BioGeoBEARS'

Afternoon - 1:00 PM to 5:00 PM, up to 40 participants

NEW ROOM: K3 in building RW [link for map]


  • Nicholas Matzke, National Institute for Mathematical and Biological Synthesis, Knoxville, TN, USA

Aim and Content:

Historical biogeography methods have long been dominated by the "dispersal versus vicariance" debate, and different computer programs have made different assumptions about the importance of these processes.  The R package BioGeoBEARS allows users to build models that give different probability to vicariance, dispersal, and other processes, as well as build more complex models (dispersal probability as a function of distance, island emergence and submergence), and all of the models are directly comparable in the common framework of statistical model choice. Attendees of this workshop will learn how to build and test models in BioGeoBEARS, as well as necessary basic skills in R and statistical model choice.

Previous experience with R is helpful, but NOT required. Attendees may wish to bring their own phylogenies and geography data and run it at the end of the workshop. Contact instructor Nick Matzke (matzke@nimbios.org) for more information
