Lianas have more acquisitive traits than trees in a dry but not in a wet forest

Journal of Ecology, Volume 109, Issue 6, Page 2367-2384, June 2021., 2021
Lianas in a dry tropical forest had a more acquisitive strategy than trees, characterized by more productive leaves and more efficient display for light interception. In dry environments, lianas appear to benefit from high‐light and nutrient‐rich soils and thus take advantage of higher resource conditions compared to trees.

Species selection and plantation management in enrichment planting with native timber species in the Panama Canal watershed

Frontiers in Forests and Global Change, 2022
Large areas of the Panama Canal Watershed have been converted to monocultures of teak (Tectona grandis), a non-native timber species that is generally not providing hoped-for economic and ecological benefits of Forest Landscape Restoration.

Large trees in tropical rain forests require big plots

PLANTS, PEOPLE, PLANET, Volume 3, Issue 3, Page 282-294, May 2021., 2021
Globally, the conservation value of big trees is linked to biodiversity and carbon sequestration. We studied trees, greater than 80 cm in diameter, in a forest in the Republic of Congo. We found that more than 100 species reach this size and the most abundant species is Sapele (Entandrophragma cylindricum), which is exploited for global timber markets.

Biomass distribution among tropical tree species grown under\ud differing regional climates [PDF]

, 2010
In the Neotropics, there is a growing interest in establishing plantations of native tree species for commerce, local consumption, and to replant on abandoned agricultural lands.

Biochar amendment did not influence the growth of two tree plantations on nutrient‐depleted Ultisols in the south Ecuadorian Amazon region

Soil Science Society of America Journal, Volume 85, Issue 3, Page 862-878, May/June 2021., 2021
Abstract The literature suggests that biochar increases the fertility of degraded, nutrient‐poor tropical soils. We hypothesized that the addition of biochar (a) increases tree growth in two plantations on Ultisols in the south Ecuadorian Amazon region, (b) reduces litterfall during the dry season because the soil remains moister, and (c) improves the ...

Long‐term ecological legacies in western Amazonia

Journal of Ecology, Volume 109, Issue 1, Page 432-446, January 2021., 2021
We documented successional dynamics in a lowland Amazonian forest setting for hundreds of years following the cessation of pre‐Columbian disturbance. We found no evidence of persistent enrichment or depletion of intentionally altered taxa (i.e. direct legacy effects) but did find evidence of indirect legacy effects that have persisted to the modern day.

Structure and Floristic Composition of Flood Plain Forests in the Peruvian Amazon I. Overstorey [PDF]

, 2001
Three Peruvian flood plain forests adjacent to the Ucayali river were sampled using nine 1 ha permanent sample plots in which stems exceeding 10 cm DBH were identified and measured. These plots were measured four times during 1993-1997.
