Abstract The cause of the terminal Pleistocene extinctions in North America is debated but is most commonly ascribed to climate change or anthropogenic overkill. Based on contemporary extinction theory from conservation biology, we predict that in a climatically induced extinction event, species with small geographic ranges are most likely to suffer extinction. We use two methods to reconstruct Pleistocene range sizes for 194 taxa using data from the FAUNMAP database to conduct analyses in… 

Pleistocene Overkill and North American Mammalian Extinctions

Clovis groups in Late Pleistocene North America occasionally hunted several now extinct large mammals. But whether their hunting drove 37 genera of animals to extinction has been disputed, largely

Global late Quaternary megafauna extinctions linked to humans, not climate change

This first species-level macroscale analysis at relatively high geographical resolution provides strong support for modern humans as the primary driver of the worldwide megafauna losses during the late Quaternary.

Constraint envelope analyses of macroecological patterns reveal climatic effects on Pleistocene mammal extinctions

Climate change and human colonization triggered habitat loss and fragmentation in Madagascar

While mid‐Holocene climate change probably triggered major demographic changes in the two lemur species range and connectivity, human settlements that expanded over the last four millennia in northern Madagascar likely played a role in the loss and fragmentation of the forest cover.

Abstract A substantial amount of archaeological data suggests groups with markedly different lithic technologies and subsistence adaptations were widespread throughout both American continents by

From Lamanai to Ka'kabish : Human and Environment Interaction, Settlement Change, and Urbanism in Northern Belize

At Lamanai and Ka’kabish, two Precolumbian Maya centres in north-western Belize, archaeologists have focused their research on the environment, architecture, and long-term occupation of the

Weighing the importance of animal body size in traditional food systems

Traditional food systems based on harvest from the local environment are fundamental to the well-being of many communities, but their security is challenged by rapid socio-ecological change. We



Ecological correlates of range shifts of Late Pleistocene mammals

There was no difference in range shifts between victims and survivors of the megafaunal extinction and the results indicate that when trying to predict species range shifts in the future, body size, lifespan and the topographic relief of the landscape should be taken into account.

Rapid body size decline in Alaskan Pleistocene horses before extinction

It is shown that horses underwent a rapid decline in body size before extinction, and it is proposed that the size decline and subsequent regional extinction at 12,500 radiocarbon years before present are best attributed to a coincident climatic/vegetational shift.

Of mice, mastodons and men: human-mediated extinctions on four continents

It is found that body size distributions of all mammals in North America, South America, Africa and Australia before and after the late Pleistocene show a similar large-size selectivity of extinctions across continents, despite differences in timing.


Abstract Much attention has been focused on the response of species to the climate change associated with the last deglaciation during the Pleistocene. Generally, species respond in an

Extinction and the spatial dynamics of biodiversity

The fossil record amply shows that the spatial fabric of extinction has profoundly shaped the biosphere; this spatial dimension provides a powerful context for integration of paleontological and neontological approaches and will be enhanced by partitioning past and present-day extinctions by driving mechanism rather than emphasizing intensity.

Climate Change, Elevational Range Shifts, and Bird Extinctions

This model that combined elevational ranges, four Millennium Assessment habitat-loss scenarios, and an intermediate estimate of surface warming of 2.8 degrees C, projected a best guess of 400-550 landbird extinctions, and that approximately 2150 additional species would be at risk of extinction by 2100.

Extinction risk from climate change

Estimates of extinction risks for sample regions that cover some 20% of the Earth's terrestrial surface show the importance of rapid implementation of technologies to decrease greenhouse gas emissions and strategies for carbon sequestration.

Determinants of loss of mammal species during the Late Quaternary ‘megafauna’ extinctions: life history and ecology, but not body size

This analysis shows two general features of the selectivity of Late Quaternary mammal extinctions in Australia, Eurasia, the Americas and Madagascar that are consistent with extinctions being due to interaction with human populations.

The predictability of extinction: biological and external correlates of decline in mammals

Geographical range size, human population density and latitude were the most consistently significant predictors of extinction risk, but otherwise there was little evidence for general, prescriptive indicators of high extinction risk across mammals.
