Ecological Modeling for Marine Mammalogists

18th Biennial Conference on the Biology of Marine Mammals: Pre-conference Workshop

Purpose of workshop
The "Ecological Modeling for Marine Mammalogists" workshop will follow on the very successful 2005 workshop "Application of GIS and Spatial-Temporal Modeling for Marine Mammal Science and Management," and will represent the fifth Biennial workshop devoted to modeling.  There is tremendous interest in applying statistical modeling techniques to the quantitative assessment of marine mammal distribution and habitat use, and our workshop seeks to explore both traditional and the latest methodologies.  Our goal is to bring together practitioners that can share their experience with various approaches to ecological modeling by addressing topics ranging from collecting data, selecting the appropriate model, evaluating the model's results, and applying those results in a management scenario.  The workshop format will consist of formal presentations followed by extended discussions during which particular methodologies can be fully explored by all participants.  In 2005, we introduced the Project Forum wherein students and less experienced researchers presented their projects and discussed the statistical challenges they are facing with an expert panel.  We plan to bring this useful forum back in 2009 so that participants of all skill levels can benefit from the workshop.
