This paper provides an overview of the contentious issue of global megafaunal extinctions in
the Late Quaternary. The main proposed causes are 'overkill', environmental change or a …

Drill cores obtained from Lake Petén Itzá, Petén, Guatemala, contain a∼ 85-kyr record of
terrestrial climate from lowland Central America that was used to reconstruct hydrologic …

The fish faunas of continental South and Central America constitute one of the greatest
concentrations of aquatic diversity on Earth, consisting of about 10 percent of all living …

The increasing aridity during the Last Glacial Maximum (LGM) has been proposed as a
major factor affecting Neotropical species. The character and intensity of this change …

An improved understanding of present-day climate variability and change relies on high-
quality data sets from the past 2 millennia. Global efforts to model regional climate modes …

Glacial–interglacial climate cycles are known to have triggered migrations and
reassortments of tropical biota. Although long-term precessionally-driven changes in …

The updated inventory of the Latin American Pollen Database (LAPD) offers a wide range of
new insights. This paper presents a systematic compilation of palynological research in …

Here we developed a composite pollen-based record of altitudinal vegetation changes from
Lake Fúquene (5° N) in Colombia at 2540 m elevation. We quantitatively calibrated Arboreal …

Pollen records from marine and terrestrial sequences in southern Europe reveal a strong
coherence between changes in tree populations and atmospheric methane concentrations …

Sundaland, a biogeographic region of Southeast Asia, is a major biodiversity hotspot.
However, little is known about the relative importance of Pleistocene habitat barriers and …
