Tropical montane forests house unusual and diverse biota and are considered highly
vulnerable to climate change, particularly near the trade wind inversion (TWI)–the upper end …

A lake sediment profile spanning the last~ 3200 years from Laguna Zoncho in the southern
Pacific region of Costa Rica was analyzed for sub-fossil chironomids. Notable shifts in …

The American Southwest has experienced a series of severe droughts interspersed with
strong wet episodes over the past decades, prompting questions about future climate …

Acetylene is a short‐lived trace gas produced during combustion of fossil fuels, biomass,
and biofuels. Biomass burning is likely the only major source of acetylene in the …

Aim Top‐down (climatic) controls of fire occurrence are expected to homogenize fire
regimes in a given area over long (millennial) temporal scales. Previous investigations in …

We present a multiproxy analysis of a sediment core from Freshwater Pond, Barbuda, one of
just a few inland paleoenvironmental records from the Lesser Antilles. Our results shed light …

Understanding the biogeography of past and present fire events is particularly important in
tropical forest ecosystems, where fire rarely occurs in the absence of human ignition. Open …

We present a lake-sediment record of pre-Columbian agriculture and fire history from the
lowlands of southern Pacific Costa Rica that captures the arrival of maize agriculture at ca …

Fire regimes across the world are expected to be altered by continuing variations in socio-
economic conditions and climate. Current global fire-vegetation models are able to …

In the southern Amazon relationships have been established among drought, human
activities that cause forest loss, fire, and smoke emissions. We explore the impacts of recent …
