Resin monoterpene defenses decline within three widespread species of pine (Pinus) along a 1530-m elevational gradient

This is a data set regarding defensive resin chemistry across a large climatic gradient in three species of pines: <i>Pinus contorta</i>, <i>Pinus ponderosa</i>, and <i>Pinus flexilis</i>. The data were collected in the Front Range of the Rocky Mountains, Boulder County, Colorado, USA. <br>The data are reported in:Ferrenberg et al. (in press) Resin monoterpene defenses decline within three widespread species of pine (Pinus) along a 1530-m elevational gradient. Ecosphere. <br>Resin chemistry is characterized by the presence/absence and concentrations of 10 individually identified monoterpenes and the pooled concentration of unidentified monoterpenes (Other Monoterpenes). <br>The total concentration, diversity (calculated as Shannon H') and dissimilarity (calculated as Bray-Curtis Dissimilarity) of monoterpenes for each individual tree are included. <br>Individual trees of each species are also characterized by their elevation of occurrence, age, diameter at breast height (DBH), radial growth of the last 5 years, and basal area increment represented by this growth.
