Evidence for climatic change across the North American Monsoon (NAM) and adjacent
areas is reviewed, drawing on continental and marine records and the application of climate …

Hydroclimate variability on multi-decadal timescales has been a prominent feature of the
circum-Caribbean region over the common era, with marked dry intervals noted in particular …

The carbon isotope composition (δ 13 C values) of long chain n-alkanes in lake sediments
has been considered a reliable means of tracking changes in the terrigenous contribution of …

Páramo is a grass-or shrub-dominated ecosystem that occupies the cool and wet upper
slopes of tropical mountains, at alpine elevations above the timber or tree line and below the …

Tropical high‐elevation lakes are considered sentinels of global climate change. This work
characterizes the hydrological conditions of tropical alpine glacial lakes located in the …

Abstract Lakes occur throughout Costa Rica, in a variety of geomorphic settings. Nearly
every possible mode of lake formation has occurred, involving processes related to …

During the last glacial cycle, greenhouse gas concentrations fluctuated on decadal and
longer timescales. Concentrations of methane, as measured in polar ice cores, show a close …

High resolution records of long chain n-alkane biomarkers from the southern South China
Sea reveal tightly response of n-alkane distribution to hydro-climate changes over the past 5 …

In the northern tropical Americas (Neotropics), notable hydrological variability has been
documented in multi-proxy paleoclimate records between∼ 600 and 1200 CE. This interval …
