Production ecology and reverse growth dominance in an old-growth ponderosa pine forest por Fernandez Tschieder, Ezequiel, Binkley, Dan, Bauerle, William

“…Dominant trees were almost 5 times larger than suppressed trees (1024 vs. 211 kg tree−1) but grew only about 2 times more than suppressed trees (4.3 vs. 1.9 kg tree−1 year−1). Dominant trees captured a lessthan-proportional amount of light relative to their size (90.4 vs. 20.9 GJ year−1 tree−1) and light use efficiency declined with tree size. …”

Eastern and Southern Africa por Collinson, Michael

“…The drier monsoon tropical climate of most of eastern and southern Africa has the world's highest solar energy intake (150 to 180 Kcal per square centimeter per year). However, its potential for crop growth (48 to 57 tons per hectare dry matter per year, assuming 3 percent conversion of light energy), is never realized due to water limitations (Cooper 1970). …”
