An ectomycorrhizal nitrogen economy facilitates monodominance in a neotropical forest.
Tropical forests are renowned for their high diversity, yet in many sites a single tree species accounts for the majority of the individuals in a stand. An explanation for these monodominant forests remains elusive, but may be linked to mycorrhizal symbioses. We tested three hypotheses by which ectomycorrhizas might facilitate the dominance of the tree, Oreomunnea mexicana, in montane tropical ...
متن کاملNitrogen and phosphorus resorption in a neotropical rain forest of a nutrient-rich soil.
In tropical forests with nutrient-rich soil tree's nutrient resorption from senesced leaves has not always been observed to be low. Perhaps this lack of consistence is partly owing to the nutrient resorption methods used. The aim of the study was to analyse N and P resorption proficiency from tropical rain forest trees in a nutrient-rich soil. It was hypothesised that trees would exhibit low nu...
متن کاملLeaf and soil nitrogen and phosphorus availability in a neotropical rain forest of nutrient-rich soil.
The nitrogen and phosphorus supply in a lowland rain forest with a nutrient-rich soil was investigated by means of the leaf N/P quotient. It was hypothesised a high N and P supply to the forest ecosystem with a N and P rich soil. Total N and extractable P were determined in the surface (10 cm) soil of three plots of the forest. Total N was analysed by the Kjeldahl method, and P was extracted wi...
متن کاملSimulating forest productivity along a neotropical elevational
31 32 A better understanding of the mechanisms controlling the magnitude and sign of carbon components in 33 tropical forest ecosystems is important for reliable estimation of this important regional component of the 34 global carbon cycle. We used the JULES vegetation model to simulate all components of the carbon balance 35 at six sites along an Andes-Amazon transect across Peru and Brazil an...
متن کاملImmediate and long-term nitrogen oxide emissions from tropical forest soils exposed to elevated nitrogen input
Tropical nitrogen (N) deposition is projected to increase substantially within the coming decades. Increases in soil emissions of the climate-relevant trace gases NO and N2O are expected, but few studies address this possibility. We used N addition experiments to achieve N-enriched conditions in contrasting montane and lowland forests and assessed changes in the timing and magnitude of soil N-o...
