Data from: Genetic parameters in subtropical pine F1 hybrids: heritabilities, between-trait correlations and genotype-by-environment interactions
Growth and stem straightness traits of 29 Pinus caribaea var. hondurensis × Pinus tecunumanii (PCH × PTEC) and 26 P. caribaea var. hondurensis × Pinus oocarpa (PCH × POOC) hybrid pair-crosses plus a total of 16 intraspecific families were assessed at ages 5, 8 and 15 years from planting at two sites
Data from: Biotic resistance to tropical ornamental invasion
We examined invasive, casual (found occasionally outside cultivation) and non-invasive (found only in cultivation) species to investigate the role of species traits and two forms of biotic resistance (plant neighbours and herbivores) in limiting invasion in Hawaiian lowlands. Seeds of 21 species of
Data from: Biotic and abiotic variables influencing plant litter breakdown in streams: a global study
Plant litter breakdown is a key ecological process in terrestrial and freshwater ecosystems. Streams and rivers, in particular, have high rates of carbon dioxide evasion and they contribute substantially to global carbon fluxes. However, there is little information available on the relative roles of
Data from: Environmental controls on canopy foliar N distributions in a neotropical lowland forest
Distributions of foliar nutrients across forest canopies can give insight into their plant functional diversity and improve our understanding of biogeochemical cycling. We used airborne remote sensing and Partial Least Squares Regression (PLSR) to quantify canopy foliar nitrogen (N) across ~164 km2
A Proterozoic Volcano-Plutonic Terrane, Gunnison and Salida Areas, Colorado
Early Proterozoic supracrustal rocks near Gunnison and Salida, Colorado include tholeiitic basalt, dacite to rhyolite, and intercalated sedimentary rocks. These were intruded by essentially synchronous gabbroic sheets, folded, and intruded by major plutons ranging from quartz diorite to granite. Pre
Reconnaissance geology of the Mississippian Leadville limestone and implications for mineralization controls, Fulford mining district, Eagle County, Colorado
Deserving of much appreciation are Russell K. Murphy, who assisted in navigating the rugged field terrain, and the E. C. Lorig family of Eagle, Colorado, whose friendship, generosity, and guidance were extremely valuable
Ponderosa pine dwarf mistletoe loss assessment survey on National Forest lands in Colorado
During 1981-82, a roadside/plot survey was conducted on National Forest lands in Colorado to estimate annual merchantable cubic-foot volume loss caused by ponderosa pine dwarf mistletoe in ponderosa pine.This survey indicated that 18 percent of the type was infested.The total annual loss of ponderos
