Tropical tree growth driven by dry-season climate variability
Zuidema, Pieter A.; Babst, Flurin; Groenendijk, Peter; Trouet, Valerie; Abiyu, Abrham; Acuña-Soto, Rodolfo; Adenesky-Filho, EduardoInterannual variability in the global land carbon sink is strongly related to variations in tropical temperature and rainfall. This association suggests an important role for moisture-driven fluctuations in tropical vegetation productivity, but empirical evidence to quantify the responsible ecological processes is missing. Such evidence can be obtained from tree-ring data that quantify variability in a major ve...
Chloroplastid pigment contents and chlorophyll a fluorescence in Amazonian trop...
Morais, Ronaldo Ribeiro de; Gonçalves, José Francisco Carvalho de; dos Santos, Ulysses Moreira; Dünisch, Oliver; Santos, André Luis dosPlants react to changes in light and hydrological conditions in terms of quantity and composition of chloroplastidic pigments, which affects the photosynthetic properties and consequently the accumulation of plant biomass. Thus, the chloroplastidic pigment concentration and chlorophyll a fluorescence of three Amazonian species (Bertholletia excelsa, Carapa guianensis e Dipteryx odorata) were investigated in sun...
Climate seasonality limits leaf carbon assimilation and wood productivity in tr...
Wagner, Fabien H.; Hérault, Bruno; Bonal, Damien; Stahl, Clément; Anderson, Liana Oighenstein; Baker, Timothy R.; Sebastian Becker, GabrielThe seasonal climate drivers of the carbon cycle in tropical forests remain poorly known, although these forests account for more carbon assimilation and storage than any other terrestrial ecosystem. Based on a unique combination of seasonal pan-tropical data sets from 89 experimental sites (68 include aboveground wood productivity measurements and 35 litter productivity measurements), their associated canopy p...
