Ecologists have long studied patterns, directions and tempos of change, but there is a
pressing need to extend current understanding to empirical observations of abrupt changes …

Abrupt ecological changes are, by definition, those that occur over short periods of time
relative to typical rates of change for a given ecosystem. The potential for such changes is …

Global vegetation over the past 18,000 years has been transformed first by the climate
changes that accompanied the last deglaciation and again by increasing human pressures; …

The Neotoma Paleoecology Database is a community-curated data resource that supports
interdisciplinary global change research by enabling broad-scale studies of taxon and …

ABSTRACT Quaternary (last 2.6 million years) botany involves studying plant megafossils
(eg tree stumps), macrofossils (eg seeds, leaves), and microfossils (eg pollen, spores) …

Dynamics in the rate of compositional change (rate-of-change; RoC), preserved in
paleoecological sequences, are thought to reflect changes due to exogenous (climate and …

We present a transient simulation of global vegetation and climate patterns of the mid-and
late Holocene using the MPI-ESM (Max Planck Institute for Meteorology Earth System …

Fire regime changes are considered a major threat to future biodiversity in the
Mediterranean Basin. Such predictions remain uncertain, given that fire regime changes and …

Accurate estimates of changes in the composition and diversity of grassland ecosystems,
and an understanding of the mechanisms responsible, are essential for predicting future …

The coupling between community composition and climate change spans a gradient from no
lags to strong lags. The no‐lag hypothesis is the foundation of many ecophysiological …
