Climate variability and forest fires in central and south‐central Chile

Ecosphere, 2018
This paper evaluates the relationship between fire occurrence (number and burned area) and climate variability (precipitation and maximum temperatures) across central and south‐central Chile (32°–43° S) during recent decades (1976–2013).

MASTREE+: Time-series of plant reproductive effort from six continents. [PDF]

Glob Chang Biol, 2022
MASTREE+ is an open‐access data set that collates reproductive time‐series data from across the globe. It includes 73,828 georeferenced observations of annual reproduction (e.g. seed and fruit counts) in perennial plant populations, consisting of 5,971 population‐level time‐series from 974 species.

Understanding climate change impacts on biome and plant distributions in the Andes: Challenges and opportunities. [PDF]

J Biogeogr, 2022
Abstract Aim Climate change is expected to impact mountain biodiversity by shifting species ranges and the biomes they shape. The extent and regional variation in these impacts are still poorly understood, particularly in the highly biodiverse Andes. Regional syntheses of climate change impacts on vegetation are pivotal to identify and guide research ...

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

Geophysical 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.

Progress in South America Dendrochronology [PDF]

, 2002
South America extends from 11°N to 62°S. Major boundaries such as the Andes on the western side of the continent and the land mass in the tropics create north-south and west-east variations in climate and ecosystems.
