Seed set coefficients of variation for two-decade periods (1900-2013) Compiled 1086 datasets of plant seed production spanning 1900-2013 and from around the world were binned into 2-decade periods for which CV (coefficient of variation) of seed set was calculated. Skewness, dip test, mean, and kurtosis were calculated for the same periods.

Objective(s) of our study were to uncover any changes in soil biogeochemistry and ecosystem properties to long-term nitrogen amendments. These data represent ecosystem property data compiled over the nine-year history of a nitrogen deposition simulation experiment. These data were collected from three sites representing a gradient of soil texture in Arches National Park. Data collection began in 2013 and continued through 2019, though metrics were collected at a range of intervals within that timeframe. These data were collected by U.S. Geological Survey field technicians using... Tags: Arches National Park, Colorado Plateau, Ecology, Geochemistry, Geography, All tags...
