Structural, physiognomic and above-ground biomass variation in savanna-forest t...
Veenendaal, Elmar M.; Torello-Raventos, Mireia; Feldpausch, Ted R.; null, Tomas; Gerard, France F.; Schrodt, Franziska; Saiz, GustavoThrough interpretations of remote-sensing data and/or theoretical propositions, the idea that forest and savanna represent "alternative stable states" is gaining increasing acceptance. Filling an observational gap, we present detailed stratified floristic and structural analyses for forest and savanna stands located mostly within zones of transition (where both vegetation types occur in close proximity) in Afri...
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...
Carbon sequestration potential of second-growth forest regeneration in the Lati...
Chazdon, Robin L.; Broadbent, Eben N.; Rozendaal, Danaë M.A.; Bongers, Frans; Zambrano, Angélica María Almeyda; Aide, T. Mitchell; Balvanera, PatriciaRegrowth of tropical secondary forests following complete or nearly complete removal of forest vegetation actively stores carbon in aboveground biomass, partially counterbalancing carbon emissions from deforestation, forest degradation, burning of fossil fuels, and other anthropogenic sources. We estimate the age and spatial extent of lowland second-growth forests in the Latin American tropics and model their p...
Edaphic, structural and physiological contrasts across Amazon Basin forest-sava...
Lloyd, Jon; null, Tomas; Schrodt, Franziska; Ishida, Francoise Yoko; Feldpausch, Ted R.; Saiz, Gustavo; Quesada, Carlos Alberto; Schwarz, MichaelSampling along a precipitation gradient in tropical South America extending from ca. 0.8 to 2.0 m ag-1, savanna soils had consistently lower exchangeable cation concentrations and higher C/N ratios than nearby forest plots. These soil differences were also reflected in canopy averaged leaf traits with savanna trees typically having higher leaf mass per unit area but lower mass-based nitrogen (Nm) and potassium ...
