Special Session - Cascades, Chains, and Webs: Alternative Approaches to Understanding Complex Systems
Broad-scale ecological studies require extensive information about diverse interacting components. Recent studies have shown a broadening of our spatial (and temporal) focus and the inclusion of a wide array of variables. Traditional statistical approaches (i.e., Fisherian statistics) do not provide an adequate method for identifying critical parameters or linking patterns of influence or causation. New approaches employing structural equation modeling, Bayesian hierarchical modeling, information theoretic model evaluation, and others have led to progress in our ability to identify and evaluate complex models. These non-traditional methods are bringing new perspective to how ecologists understand relationships among interacting mechanisms and how influence ‘travels’ through an ecosystem. This symposium/session aims to demonstrate some of these new approaches regardless of study focus or system. Through interaction we can learn from our successes and failures in hopes of improving our ability to investigate multivariate systems. Anyone focusing on multivariate systems large or small is invited.
