Abstract Key message At the sixth and seventh years of a drought event in south Chile, non-structural carbohydrate (NSC) concentrations were similar between healthy unhealthy trees Araucaria araucana (Molina) K. Koch, growth did not decrease, suggesting that leaf loss prevented C shortage trees. Context Tree resistance resilience may be impaired by decreasing carbohydrates (NSC). During 7-year drought, isohydric species (Araucariaceae) evidenced decline (foliage browning). Aims To determine...
Abstract Herbivorous insects alter biogeochemical cycling within forests, but the magnitude of these impacts, their global variation, and drivers this variation remain poorly understood. To address knowledge gap help improve models, we established a network 74 plots 40 mature, undisturbed broadleaved forests. We analyzed freshly senesced green leaves for carbon, nitrogen, phosphorus silica concentrations, foliar production herbivory, stand-level nutrient fluxes. show more release by insect...

Lianas can negatively affect their host tree. The evidence comes from studies in tropical forests, where lianas decrease the growth rate and reproduction of This is primarily a consequence water nutrient competition, two limiting factors forests. In contrast, for some areas southern temperate rainforests competition these resources could be less severe, because high rainfall fertile soils. But so far, no study has determined effect liana over tree rainforests. aim this was to evaluate, field...
There is a strong decrease in liana diversity along latitudinal and altitudinal gradients at global scale, there marked difference between tropical temperate ecosystems. From these observations, it has been proposed that cold temperatures would restrict the ecological patterns of because their vascular system's vulnerability to freeze-thaw embolism. Our objective was establish functional mechanism drives loss temperature gradient. We evaluate performance 10 different species based on apical...
1.- There is a strong decrease in liana diversity along latitudinal and altitudinal gradients at global scale, there marked difference between tropical temperate ecosystems. From these observations it has been proposed that cold temperatures would restrict the ecological patterns, because of vulnerability their vascular system to freezing-thaw embolism. However, scarce empirical evidence support this idea natural conditions. 2.- The goal our study was establish functional mechanism behind...
