The role of environmental change in the late Pleistocene megafaunal extinctions remains a key question, owing in part to uncertainty about landscape changes at continental scales. We investigated the influence of environmental changes on megaherbivores using bone collagen nitrogen isotopes (n = 684, 63 new) as a proxy for moisture levels in the rangelands that sustained late Pleistocene grazers. An increase in landscape moisture in Europe, Siberia and the Americas during the Last Glacial… 

Late Pleistocene shrub expansion preceded megafauna turnover and extinctions in eastern Beringia

Postglacial expansion of shrub tundra preceded the regional extinctions of horse and mammoth and began during a period when the frequency of 14C dates indicates large grazers were abundant, indicating climate was the primary control of steppe-tundra persistence and that climate-driven vegetation change may pose threats to faunal diversity in the future.

Nitrogen palaeo-isoscapes: Changing spatial gradients of faunal δ15N in late Pleistocene and early Holocene Europe

Nitrogen isotope (δ15N) analysis of animal tissue is widely used in archaeology and palaeoecology to investigate diet and ecological niche. Data interpretations require an understanding of nitrogen

Life histories and niche dynamics in late Quaternary proboscideans from Midwestern North America: evidence from stable isotope analyses

This study further refines the ecology of midwestern mammoths and mastodons demonstrating increasing seasonality and niche overlap as they responded to landscape changes in the final millennia before extinction.

Tracking late-Quaternary extinctions in interior Alaska using megaherbivore bone remains and dung fungal spores

Abstract One major challenge in the study of late-Quaternary extinctions (LQEs) is providing better estimates of past megafauna abundance. To show how megaherbivore population size varied before and

Life histories and niche dynamics in late Quaternary proboscideans from midwestern North America

Abstract Stable isotopes of mammoths and mastodons have the potential to illuminate ecological changes in late Pleistocene landscapes and megafaunal populations as these species approached

Climate‐driven ecological stability as a globally shared cause of Late Quaternary megafaunal extinctions: the Plaids and Stripes Hypothesis

An integrative hypothesis is asserted that an underlying cause of Late Quaternary megafaunal extinctions was a fundamental shift in the spatio‐temporal fabric of ecosystems worldwide, triggered by the loss of the millennial‐scale climate fluctuations that were characteristic of the ice age but ceased approximately 11700 years ago on most continents.

A new terrestrial palaeoenvironmental record from the Bering Land Bridge and context for human dispersal

It is found that the timing of the earliest unequivocal human dispersals into Alaska, based on archaeological evidence, corresponds with a shift to warmer/wetter conditions on the BLB between 14 700 and 13 500 years ago associated with the early Bølling/Allerød interstadial.

Synergistic roles of climate warming and human occupation in Patagonian megafaunal extinctions during the Last Deglaciation

Increased resolution provided by the Patagonian material reveals that the sequence of climate and extinction events in North and South America were temporally inverted, but in both cases, megafaunal extinctions did not occur until human presence and climate warming coincided.

Abrupt warming events drove Late Pleistocene Holarctic megafaunal turnover

The presence of many cryptic biotic transitions before the Pleistocene/Holocene boundary revealed by ancient DNA confirms the importance of climate change in megafaunal population extinctions and suggests that metapopulation structures necessary to survive such repeated and rapid climatic shifts were susceptible to human impacts.

New carbon dates link climatic change with human colonization and Pleistocene extinctions

Many new radiocarbon dates are added to those already published on late Pleistocene fossils from Alaska and the Yukon Territory and show previously unrecognized patterns, indicating a radical ecological sorting during a uniquely forage-rich transitional period, affecting all large mammals, including humans.

Steppe-Tundra Transition: A Herbivore-Driven Biome Shift at the End of the Pleistocene

Results indicate that mammalian grazers have a sufficiently large effect on vegetation and soil moisture that their extinction could have contributed substantially to the shift from predominance of steppe to tundra at the Pleistocene-Holocene boundary.

Life and extinction of megafauna in the ice-age Arctic

It follows that long-distance dispersal was crucial for the long-term persistence of megafaunal species living in the Arctic and implies that regional extinctions followed by population reestablishment from distant refugia were characteristic features of ice-age biogeography at high latitudes.
