GAPS AND ROOT TRENCHING INCREASE TREE SEEDLING GROWTH IN PANAMANIAN SEMI-EVERGREEN FOREST

Ignacio M. Barberis; Edmund V. J. Tanner Ecology 2005. doi:10.1890/04-0677

Other claims from this paper (10)

Intervention effect Gaps increased Simarouba seedling growth by 684%.
Intervention effect Gaps increased Aspidosperma seedling growth by 364%.
Intervention effect Gaps increased Tachigali seedling growth by 324%.
Intervention effect Gaps decreased tree seedling mortality.
Intervention effect Trenching in gaps increased Simarouba seedling growth by 49%.
Intervention effect Trenching in gaps increased Gustavia seedling growth by 63%.
Intervention effect Trenching in gaps increased Aspidosperma seedling growth by 38%.
Intervention effect Trenching had very small effects on growth in the understory.
Intervention effect Trenching did not affect seedling mortality.
Mechanism The authors infer that trenching increased growth through nutrients in the wet season and water or nutrients in the dry season.

Flood tolerance of four tropical tree species

O. R. Lopez; T. A. Kursar Tree Physiology 1999. doi:10.1093/treephys/19.14.925

Other claims from this paper (11)

Intervention effect Flooding reduced photosynthesis at Day 45 in all four species by 10-30%.
