Individual-based modeling of amazon forests suggests that climate controls prod...
Fauset, Sophie; Gloor, Manuel U.; Fyllas, Nikolaos M.; Phillips, Oliver L.; Asner, Gregory P.; Baker, Timothy R.; Patrick Bentley, LisaClimate, species composition, and soils are thought to control carbon cycling and forest structure in Amazonian forests. Here, we add a demographics scheme (tree recruitment, growth, and mortality) to a recently developed non-demographic model—the Trait-based Forest Simulator (TFS)—to explore the roles of climate and plant traits in controlling forest productivity and structure. We compared two sites with diffe...
Leaf-level photosynthetic capacity in lowland Amazonian and high-elevation Ande...
Bahar, Nur H.A.; Ishida, Francoise Yoko; Weerasinghe, Lasantha K.; Guerrieri, Rossella; O'Sullivan, Odhran S.; Bloomfield, Keith J.; Asner, Gregory P.We examined whether variations in photosynthetic capacity are linked to variations in the environment and/or associated leaf traits for tropical moist forests (TMFs) in the Andes/western Amazon regions of Peru. We compared photosynthetic capacity (maximal rate of carboxylation of Rubisco (Vcmax), and the maximum rate of electron transport (Jmax)), leaf mass, nitrogen (N) and phosphorus (P) per unit leaf area (M...
Phylogenetic diversity of Amazonian tree communities
Honorio Coronado, Euridice N.; Dexter, Kyle Graham; Pennington, R. Toby; Chave, Jérôme; Lewis, Simon L.; Alexiades, Miguel N.; Alvarez, EstebanAim: To examine variation in the phylogenetic diversity (PD) of tree communities across geographical and environmental gradients in Amazonia. Location: Two hundred and eighty-three c. 1 ha forest inventory plots from across Amazonia. Methods: We evaluated PD as the total phylogenetic branch length across species in each plot (PDss), the mean pairwise phylogenetic distance between species (MPD), the mean nearest...
