Climate drivers of seed production in Picea engelmannii and response to warming temperatures in the southern Rocky Mountains

Publications Posted on: June 24, 2016
The increases in seed output observed in this study may promote population fitness of P. engelmannii in the face of changing climate regimes and increasing frequencies of fire- and insect-related tree mortality in the Rocky Mountains.

Seed and ring width data from 'Climate drivers of seed production in Picea engelmannii and response to warming temperatures in the southern Rocky Mountains'

Datasets Posted on: June 08, 2016
Seed production by Picea engelmannii was monitored at 13 plots distributed across an approximately 670 meter elevation gradient in the Fraser Experimental Forest near Fraser, Colorado. Seeds were collected annually between 1970 and 2010 from ten wire mesh seed traps located in each of the 13 plots. Annual plot level estimates of seed abundance were derived from an average value of the 10 traps.

Mechanisms for maintenance of dominance in a nonclonal desert shrub

Publications Posted on: January 12, 2016
Blackbrush (Coleogyne ramosissima: Rosaceae) is a slow-growing, non-clonal shrub that is regionally dominant on xeric, shallow soils in the North American Mojave Desert-Great Basin transition zone and southern Colorado Plateau. Blackbrush seed production is concentrated in mast years, and most seeds are cached and later consumed by heteromyid rodents.
