CR Workshop 20-24 March 2017 in Montpellier, France

Postby rplp » Tue Sep 27, 2016 11:19 am

Upcoming workshop on the analysis of capture-recapture data using multievent models to be held at Center for Evolutionary and Functional Ecology (CEFE), Montpellier, France, 20-24 March 2017. The registration of participants will be at CEFE March 20 at 13:30 and the workshop will start immediately after at 14:00. Two and a half days of lectures and practical exercises will be followed by one day (Thursday 23) of practical work on the participants' data and a half day (Friday 24) of presentations and discussions of the results.

You are hereby cordially invited to take part in the following workshop:


organized by the Biostatistics and Population Biology team of CEFE in Montpellier (France)

The estimation of population parameters (survival, recruitment, dispersal, and population growth rate) is critical to many areas of fundamental and applied biology. The major source of data for such estimation comes from observations of marked animals. This workshop will deal with recent advances in the analysis of such data. The content is aimed at providing the participants with a solid background in the philosophy, theory and practices for the analysis of data from marked animals, with a specific focus on multievent data and models. Multievent capture-recapture models are a natural generalization of the multisite recapture models. Similarly, individuals are sampled on discrete occasions, at which they may be captured or not. However, contrary to the multisite case, uncertainty in the assessment of state such as “breeder”, “diseased” or “highly catchable” can be incorporated into the analysis. Conceptually, it is not states that are observed but rather something dubbed an "event" (a particular breeding behaviour, a positive blood test or just encounter), which reflects to some extent the underlying state. The presence of imperfect observations and the lack of information on individual quality presently make multievent models an invaluable tool in virtually any area of population biology. Current applications include the study of dispersal, epidemiology, individual heterogeneity, mixture of information... New developments allow the treatment of individual heterogeneity through random effects as well as through mixture models, and the inclusion of individual as well as environmental covariates. For examples of topics that can be addressed in the multievent framework, see the non-exhaustive bibliography below. Depending on the majority of participants wishes, one of the following themes will be developed during the workshop:
  • stopover
  • epidemiology
  • site occupancy

Emphasis will be placed on stringent procedures for building and selecting the most appropriate models for the data set at hand, in order to be able to draw reliable biological conclusions.

Format of the workshop will be a combination of lectures and computer lab exercises with the programs E-SURGE and U-CARE. ( U-CARE incorporates goodness-of-fit tests for multistate models, and E-SURGE makes the building of complex models easy based on a language describing the structure of models in a compact and user-friendly way. All lectures and course material will be in English.

It is our hope that participants will bring their own capture-recapture data to work on them during the workshop. To take full advantage of the workshop, it is expected that the participants will have some basic practice of the analysis of CR data.

Teachers: Roger Pradel, Rémi Choquet, Olivier Gimenez, Loreleï Guéry, and Meritxell Genovart.

Participants will have to provide their own laptop computer that is capable of running Windows-based software.

Thank you for disseminating this message to colleagues and students who may not have received it.
