Tropical tree growth driven by dry-season climate variability

Interannual 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...

Dendrochronology and climate in the Brazilian Atlantic Forest: Which species, w...

As dendrochronology noticeably increased in tropical regions during the last three decades, some general patterns could emerge from comprehensive analyses of case studies. Here, we investigated the state of dendrochronology’s contributions to the bioclimatology of wood species in the Brazilian Atlantic Forest (AF). We asked: Which species and sites had cross-datable growth-ring series suitable for bioclimatic i...

Climate seasonality limits leaf carbon assimilation and wood productivity in tr...

The 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...

Anatomia e aspectos filogeneticos do xilema secundario de 10 especies de Annona...

O presente trabalho engloba o estudo anatômico e os aspectos de importância filogenética do xilema secundário de 10 espécies de Annonaceae, com ocorrência natural no Estado de Santa Catarina. Foram estudadas as seguintes espécies: Annona cacans (Warm.) var. glabriuscula R. E. Fries, Annona glabra L., Duguetia lanceolata St. Hil., Guatteria australis St. Hil., Porcelia macrocarpa (Warm.) R. E. Fries, Rollinia em...

Eucalyptus grandis Hill.ex. Maiden injuries caused by Ctenarytaina spatulata Ta...

The injuries of Ctenarytaina spatulata Taylor, 1977, were characterized through observations in field,  laboratory and greenhouse. The first injuries of C. spatulata in Eucalyptus grandis are caused during  oviposition. At the point where the egg is inserted, a   small black spot appears, which may grow larger, causing the bud death. The insect eliminates large  amount of honeydew, accumulating on leaves and  a...
