Amazon forest ecosystem responses to elevated atmospheric Co2 and alterations i...
Hofhansl, Florian; Andersen, Kelly M.; Fleischer, Katrin; Fuchslueger, Lucia; Rammig, Anja; Schaap, Karst J.; Valverde-Barrantes, Oscar J.The impacts of elevated atmospheric CO2 (eCO2) and alterations in nutrient availability on the carbon (C) storage capacity and resilience of the Amazon forest remain highly uncertain. Carbon dynamics are controlled by multiple eco-physiological processes responding to environmental change, but we lack solid experimental evidence, hampering theory development and thus representation in ecosystem models. Here, we...
Ant-tended hemiptera in Amazonian myrmecophytes: Patterns of abundance and impl...
Lapola, David Montenegro; Bruna, Emilio M.; Willink, Cristina Granara de; Vasconcelos, Heraldo L.We assessed how the abundance of ant-tended Hemiptera associated with two Amazonian myrmecophytes, Tococa bullifera and Maieta guianensis, varied as a function of resident ant species. We collected five species or morpho-species of adult hemiptera in the domatia of M. guianensis, with four of these species also found in Tococa bullifera. Maieta guianensis plants inhabited by Crematogaster laevis had over four-f...

Pereira, Iokanam Sales; do Nascimento, Henrique E.Mendonça; Vicari, Matheus Boni; Disney, Mathias I.; DeLucia, Evan H.; null, Tomas; Kruijt, Bart J.Tropical vegetation biomass represents a key component of the carbon stored in global forest ecosystems. Estimates of aboveground biomass commonly rely on measurements of tree size (diameter and height) and then indirectly relate, via allometric relationships and wood density, to biomass sampled from a relatively small number of harvested and weighed trees. Recently, however, novel in situ remote sensing techni...
