Drought is a nationwide threat to biodiversity.
Long-term consequences of drought are unpredictable because each organism responds not only to drought, but also other organisms. Even species insensitive to drought will be influenced if the plants it feeds on or the predator that consumes it respond to drought.
We employ a novel generalized joint attribute modeling (gjam) approach to identify how interactions between different species determine the effects of drought.
Detailed descriptions of this project are available in the links at the top of this page.

Unlike descriptive ordinations, it is fully probabilistic. Unlike structural equation models it accommodates each of the three challenges mentioned above.
First analyses have been applied to traits across eastern North America (Clark 2016). The full model applied to trees and microbiome data is in revision (Clark et al. 2016). Dimension reduction - which allows us to apply the model to hundreds of species simultaneously - is in revision (Taylor-Rodriquez et al. 2016).
