Impactos del cambio climático en la biodiversidad de los Andes tropicales: Riesgo climático, vulnerabilidad y herramientas de toma de decisiones para la planificación de la conservación

The project addresses the lack of long-term climate data in the tropical Andes by combining dendrochronology, improved hydrometeorological networks, in-situ digital sensors, and global circulation models. These diverse data streams—including tree-ring chronologies spanning 100 to 200 years and simulations for 2011-2030 and 2045-2065—are integrated to reduce uncertainty in climate projections and inform the NatureServe vulnerability index for conservation management.

• Due to the limited nature of historical hydrometeorological records, the project used classical dendrochronology (tree-ring analysis) to reconstruct past climate conditions over 100 to 200 years. Key species were selected from páramo, High-Andean forest, and upper cloud forest environments, specifically using Weinmannia cochensis and Ocotea sericea in the northern Ecuadorian Andes, and Polylepis pepei and Pseudolmedia rigida in the border region between Bolivia and Peru.
• To improve data density and quality, the project implemented statistical tools via the RClimdex package to homogenize historical series and installed digital sensors at approximately 500-meter altitudinal intervals across gradients of 4,500 meters to collect hourly temperature, humidity, and dew point data.
• Future climate conditions were estimated using global circulation models (including ECHAM4.5, GFDL, CCM3v6, and MRI) and reanalysis data from NOAA NCEP-DOE. Prospective simulations focused on short-term (2011-2030) and medium-term (2045-2065) horizons, incorporating altitudinal corrections to account for the Andean orography.
• The project integrated tree-ring chronologies, long-term climate indices, global circulation model simulations, reanalysis data, and local altitudinal temperature/humidity patterns to develop short- and medium-term scenarios for the climate exposure module of the NatureServe vulnerability index.
