Resources for Ecometrics

Learning and Teaching Resources

Ecometrics Slides

These slides depict theory and examples of ecometrics, a trait-based, community-based approach to interactions between organisms and environments. Includes maps of ecometric traits in living vertebrates, overview diagrams explaining trait-environment relationships, and a bibligraphy of references to the images.

Ecometric Terms

Definitions of common ecometric terms from Polly & Head, 2015. [PDF Format, 55 Kb, click cover at right to download]

Overview of Ecometrics

Review paper by Polly and Head (2015) that explains the principles of ecometrics, with applied examples from carnivore limb traits and herbivore tooth crown heights. Topics covered include functional trait distributions in living vertebrates, functional trait turnover in the fossil record, effects of anthropogenic change on functional trait patterns, and probabalistic approaches to studying the trait-environment relationship.

Ecometric Data Resources

Geography and Climate Sampled at 50km

These relational database tables contain elevation, climate, vegetation, and ecological region data that have been resampled using a grid of points spaced equidistantly at 50km. Equidistant spacing circumvents the spatial bias that arises poleward in data gridded by latitude and longitude. 50km spacing is approximately the grain size for paleontological assemblages, which can often include individuals transported by predators and fluvial activity.
