Evaluation of rangeland gross primary productivity sensitivity potential to drought using ecosystem modelling
Gross primary productivity is one of the most important factors in the carbon cycle of terrestrial ecosystems. With global warming increase, the frequent drought events and the specific response of regional vegetation to these changes, it is essential to identify and quantify the relationships between climatic and GPP data in arid region. In this study, the responses of gross primary productivi...
متن کاملContributions of woody and herbaceous vegetation to tropical savanna ecosystem productivity: a quasi-global estimate.
To estimate the relative contributions of woody and herbaceous vegetation to savanna productivity, we measured the 13C/12C isotopic ratios of leaves from trees, shrubs, grasses and the surface soil carbon pool for 22 savannas in Australia, Brazil and Ghana covering the full savanna spectrum ranging from almost pure grassland to closed woodlands on all three continents. All trees and shrubs samp...
متن کاملThe allocation of ecosystem net primary productivity in tropical forests.
The allocation of the net primary productivity (NPP) of an ecosystem between canopy, woody tissue and fine roots is an important descriptor of the functioning of that ecosystem, and an important feature to correctly represent in terrestrial ecosystem models. Here, we collate and analyse a global dataset of NPP allocation in tropical forests, and compare this with the representation of NPP alloc...
متن کاملEcosystem size predicts eco‐morphological variability in a postglacial diversification
Identifying the processes by which new phenotypes and species emerge has been a long-standing effort in evolutionary biology. Young adaptive radiations provide a model to study patterns of morphological and ecological diversification in environmental context. Here, we use the recent radiation (ca. 12k years old) of the freshwater fish Arctic charr (Salvelinus alpinus) to identify abiotic and bi...
