2018 Annual Symposium Program Workshops


Based on feedback from the 60th IAVS Symposium in Palermo, we scheduled a full day for workshops and working group meetings. Rooms will be provided on MSU campus for groups to meet Sunday July 22 for half- or full-day sessions. 
 

The following two workshops will take place. If you would like to attend a workshop, please contact the organizer of that workshop at the e-mail address shown below. If you would like to hold a working group or section meeting on Sunday, July 22, please contact the symposium organizers and let them know the number of people and the time slot you would prefer.

 

Rethinking biomes – towards a consistent high-level classification of global vegetation

Organizers: Scott Franklin, J├╝rgen Dengler, and John Hunter
Contact email: Scott.Franklin@unco.edu

This workshop is being organized by the IAVS-Vegetation Classification Working Group and is a follow-up to a workshop that took place at last year’s IAVS Symposium in Palermo, Sicily.

Biomes are top-level divisions of the terrestrial biosphere describing physiognomy and function of the vegetation shaped by current environmental conditions, while realms describe the taxonomic composition of floras, reflecting past environmental conditions and evolutionary history. Both regionalizations are widely used in fundamental and applied ecological research, but the biome concept lacks a generally agreed definition. The workshop in Bozeman has three aims. (1) Reviewing the existing global biome typologies and a selection of continental systems with regard to a multitude of aspects, including the definition and terminology of biomes, the number of biomes distinguished, criteria used to derive a biome map and its resolution, frequency of application of a particular biome typology and experiences from its use. This activity should lead to a joint review and synthesis paper in an international journal. (2) Comparing digital maps of existing biome typologies for their spatial congruencies and discrepancies as well as their climatological “content”. (3) Discuss how the concept “biome” should be defined in order to be most useful for science and how a new global biome map meeting this concept can be derived. Our plan is to finalise the paper (1) on or shortly after the workshop, thus most of the time will be devoted to this product; by contrast points (2) and (3) aim at publications at medium term and thus the discussion here will only be initialised in Bozeman. Points (1) and (2) can be dealt with most effectively if materials are already compiled and maps digitised prior to the workshop. Thus, volunteers willing to help with such activities are invited to contact juergen.dengler@uni-bayreuth.de.


Fundamentals of structural equation modeling

Organizer: James B. Grace
Contact email: gracej@usgs.gov
 
This workshop will describe the fundamental principles of structural equation modeling (SEM), illustrate basic techniques, and give overviews for more advanced methods. The goals of the workshop are to (a) present the rationale for working with structural equation models, (b) provide an overview of the fundamental principles of SEM, (c) illustrate basic modeling procedures using the lavaan package in R, and (d) illustrate approaches that permit more complex specifications. Participants will be exposed to a series of topic-specific modules designed to develop confidence in designing, fitting, and assessing basic models. Access to additional online tutorials as further resources will also be provided. Participants need basic familiarity with introductory statistics and the R Statistical Platform. Brief pre-workshop and post-workshop exercises will be provided, but we will not attempt in-class hands-on modeling in this one-day class for the economy of time. Please contact the organizer if you are interested in attending this workshop.
