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...
Hyperdominance in Amazonian forest carbon cycling
Fauset, Sophie; Johnson, Michelle O.; Gloor, Manuel U.; Baker, Timothy R.; Monteagudo M, Abel; Brienen, Roel J.W.; Feldpausch, Ted R.While Amazonian forests are extraordinarily diverse, the abundance of trees is skewed strongly towards relatively few â € hyperdominantâ €™ species. In addition to their diversity, Amazonian trees are a key component of the global carbon cycle, assimilating and storing more carbon than any other ecosystem on Earth. Here we ask, using a unique data set of 530 forest plots, if the functions of storing and produci...
Contrasting controls on tree ring isotope variation for Amazon floodplain and t...
Cintra, Bruno Bar?ante Ladvocat; Gloor, Manuel U.; Boom, Arnoud; Schöngart, Jochen; Locosselli, Giuliano Maselli; Brienen, Roel J.W.Isotopes in tropical trees rings can improve our understanding of tree responses to climate. We assessed how climate and growing conditions affect tree-ring oxygen and carbon isotopes (δ18OTR and δ13CTR) in four Amazon trees. We analysed within-ring isotope variation for two terra firme (non-flooded) and two floodplain trees growing at sites with varying seasonality. We find distinct intra-annual patterns of δ1...
Tropical forest light regimes in a human-modified landscape
Fauset, Sophie; Gloor, Manuel U.; Aidar, Marcos P. M.; Freitas, Helber C. [UNESP]; Fyllas, Nikolaos M.; Marabesi, Mauro A.; Rochelle, Andre L.

No. of bitstreams: 0 Previous issue date: 2017-11-01; Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Natural Environment Research Council; Light is the key energy input for all vegetated systems. Forest light regimes are complex, with the vertical pattern of light within canopies influenced by forest structure. Human disturbances in tropica...
