Human-mediated species invasion and climate change are leading to global extinctions and
are predicted to result in the loss of important axes of phylogenetic and functional diversity …

Distributions of biotas are predictably structured along environmental gradients. Vegetation
is primarily restricted by precipitation and temperature, whereas, most mammals are limited …

Recent studies connecting the decline of large predators and consumers with the
disintegration of ecosystems often overlook that this natural experiment already occurred. As …

Rich fossil deposits of the late Quaternary help us understand responses of biodiversity to
global change and thus predict the future of ecosystems. Studies from the late Quaternary …

The late Quaternary of North America was marked by prominent ecological changes,
including the end‐Pleistocene megafaunal extinction, the spread of human settlements and …

The long-standing view that Mesozoic mammaliaforms living in dinosaur-dominated
ecosystems were ecologically constrained to small size and insectivory has been …

Mid-Pleistocene vertebrates in North America are scarce but important for recognizing the
ecological effects of climatic change in the absence of humans. We report on a uniquely rich …

Earth has experienced five major extinction events in the past 450 million years. Many
scientists suggest we are now witnessing a sixth, driven by human impacts. However, it has …

Climate change alters species distributions, causing plants and animals to move north or to
higher elevations with current warming. Bioclimatic models predict species distributions …

Small mammal communities in western North America experienced declines in taxonomic
richness across the late Pleistocene to Holocene transition (PHT), a recent natural global …
