WebDec 13, 2024 · Canopy composition in mixed Patagonian Nothofagus forests has an impact on soil properties like cationic exchange capacity and pH, while most soil variables changed with site [P, cation exchange capacity (CEC), soil moisture (SM), resistance to penetration (R)]. Site conditions and canopy composition need be considered together to better … WebJul 22, 2016 · Basal area increment (BAI) data from 294 Nothofagus trees at 11 stands in a 500-km latitudinal transect along the forest–steppe ecotone were used to identify the dominant patterns of regional growth. Three Regional dominant patterns, showing common variations in BAI, were derived.

WebJan 14, 2024 · The forests in the area are dominated by deciduous broad-leaved N. pumilio and they extend along a west-to-east elevation gradient ranging from about 950–1100 to 500 m.a.s.l. Forests present well-developed and erect N. pumilio individuals of varying height (10 to 20 m) along the elevational gradient with the exception of the upper altitudinal … At one time it was believed that the Eastern Australian populations could not reproduce in present-day conditions, except by suckering (asexual reproduction), being remnant forest from a cooler time. It has since been shown that sexual reproduction may occur, but distribution in cool, isolated high-altitude environments at temperate and tropical latitudes is consistent with the theory tha…
WebEmphasis is placed on the role synchronised cohort mortality in the dynamics of beech (Nothofagus) forest in New Zealand. Mature populations are frequently relatively even-aged and have size structures which render them vulnerable to exogenous disturbances from which they cannot recover, except by regeneration.
