The database of the PREDICTS (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems) project

open access: yesEcology and Evolution, Volume 7, Issue 1, Page 145-188, January 2017., 2017
The collation of biodiversity datasets with broad taxonomic, biogeographic, and spatial extents is necessary to understand historical declines and to project—and hopefully avert—future declines. We describe and make freely available a database of more than 3.2 million biodiversity measurements from 94 countries representing over 47,000 species ...

The PREDICTS database: a global database of how local terrestrial biodiversity responds to human impacts

open access: yesEcology and Evolution, Volume 4, Issue 24, Page 4701-4735, December 2014., 2014
The collation of biodiversity datasets with broad taxonomic and biogeographic extents is necessary to understand historical declines and to project – and hopefully avert – future declines. We describe a newly collated database of more than 1.6 million biodiversity measurements from 78 countries representing over 28,000 species, collated from existing ...

Stream Water Chemistry along an Elevational Gradient from the Continental Divide to the Foothills of the Rocky Mountains

open access: yesVadose Zone Journal, Volume 10, Issue 3, Page 900-914, August 2011., 2011
Small changes in the flux of energy, chemicals, and water to mountain catchments may invoke large changes in the local climate, ecosystem dynamics, and water quantity and quality. The Landscape Continuum Model (LCM) was developed in part to improve our understanding of how high‐elevation ecosystems might respond to future perturbations.
