Missouri bladderpod (Lesquerella filiformis) is a federally threatened plant species found in southwest Missouri and northern Arkansas. Understanding how Missouri bladderpod abundance changes through time in relation to its heterogeneous glade habitat is crucial for successful conservation of the species. Abundance of Missouri bladderpod and percent cover of several of its habitat’s attributes were recorded over four years. Coherently integrating both the spatial and temporal information within this data set is challenging, as there are few well developed analytic methods to accomplish this. In this study, we analyzed this spatially explicit ecological data using various statistical approaches. ANOVA, repeated measures analysis, and log-linear modeling were used in temporal analyses of the abundance of Missouri bladderpod, while the spatial component of the data set was probed within a Geographical Information System software environment. The approaches used can be applied to many different problems in habitat modeling and conservation biology.
