A process-based forest growth model, 3-PG (Physiological Principles Predicting
Growth), parameterized with values of soil properties constrained by satellite-derived
estimates of maximum leaf area index (LAI[subscript max]), was run for Douglas-fir (Pseudotsuga
menziesii) to contrast the extent to which site growth potential might vary across western
North America between a...
Vegetation carbon uptake and respiration constitute the largest carbon cycle of the planet with an annual turnover
in the order of 120 GT. Currently, neither ecosystem carbon uptake (through photosynthesis) nor ecosystem
carbon release (through respiration) can be measured directly during the daytime. Instead, flux-tower measurements
rely on nighttime respiration...
People in the US and Europe eat the most meat worldwide, lose or waste about 20% of this product overall, and they waste the most food per capita. Food waste is currently addressed as an issue of volume, so programs and policies target foods that are wasted more by weight...
Alzheimer’s Disease (AD) is a neurodegenerative pathology currently affecting nearly 44 million individuals worldwide, yet there are not currently any effective treatments or preventions for AD despite the rapid development in our understanding of the disease over the last four decades. The medical and sanitary innovations of the last century...
