Soil respiration and mass balance estimation of fine root production in Fitzroya cupressoides forests of southern Chile

open access: yesEcosphere, 2017
The soil carbon dynamics of southern hemisphere temperate rainforests have rarely been studied. Here, we report for the first time soil CO2 effluxes and their partitioning for medium‐age and old‐growth Fitzroya cupressoides forests growing under ...

Hydroclimate and ENSO Variability Recorded by Oxygen Isotopes From Tree Rings in the South American Altiplano

open access: yesGeophysical Research Letters, Volume 49, Issue 4, 28 February 2022., 2022
Abstract Hydroclimate variability in tropical South America is strongly regulated by the South American Summer Monsoon (SASM). However, past precipitation changes are poorly constrained due to limited observations and high‐resolution paleoproxies.
