Declines in North American megafauna populations began before the Clovis period and were the cause, not the result, of vegetation changes and increased fires. One of the most dramatic environmental changes in recent Earth history has been the disappearance of very big animals—mammoths, mastodons, ground sloths, giant kangaroos, moa and hundreds of others—from most of the land area of the globe. What caused these extinctions? And how did they affect the world's ecosystems? The first question has… Expand

Extinctions in North America's Late Glacial landscapes
Human-caused extinctions of terrestrial mammals in large parts of the world such as North America may have been side-effects of rapid long-distance dispersals (biogeographic range-change) by HomoExpand
Genetic data suggest a natural prehuman origin of open habitats in northern Madagascar and question the deforestation narrative in this region
TLDR
It is shown that contrary to most regions of Madagascar, the forest cover in Daraina remained remarkably stable over the past 60 y, and the golden-crowned sifaka, a forest-dwelling lemur, underwent a strong population contraction before the arrival of the first humans, hence excluding an anthropogenic cause.

Towards a Middle Pleistocene terrestrial climate reconstruction based on herpetofaunal assemblages from the Iberian Peninsula: State of the art and perspectives
Abstract The pattern of the varying climatic conditions in southern Europe over the last million years is well known from isotope studies on deep-ocean sediment cores and the long pollen records thatExpand
Development of the European Russian Forests in the Holocene
The history of forest landscapes in European Russia since the time of the Late Pleistocene is shortly reviewed. Human activities are considered a leading factor in the changes of the forestExpand

Ecological consequences of forest elephant declines for Afrotropical forests.
TLDR
The roles of forest elephants in seed dispersal, nutrient recycling, and herbivory and physical damage are evaluated to predict the cascading ecological effects of their population declines and likely means Central African forests will be more like Neotropical forests, from which megafauna were extirpated thousands of years ago.

Non-pollen palynomorphs as an aid to the identification of ancient farming activities : an experimental and archaeological approach
This research aims to assess the potential of non-pollen microfossils in archaeological research, as this evidence provides an important and previously overlooked contribution to the investigationExpand
Fossil pigmy rattlesnake inside the mandible of an American mastodon and use of fossil reptiles for the paleoclimatic reconstruction of a Pleistocene locality in Puebla, Mexico
Abstract Records of Pleistocene reptiles are relatively well known in different countries. However, reptile fossil records of Pleistocene from Latin America are scarce and limited to presence dataExpand
Late pleistocene passerine birds from Sonora, Mexico
TLDR
Among the few Pleistocene sites from Mexico or the United States with well-studied and substantial assemblages of fossil passerines, Terapa is unique in its dominance of icterids (which may be common elsewhere but not dominant) and in its absence of corvids. Expand

Pleistocene Megafaunal Collapse, Novel Plant Communities, and Enhanced Fire Regimes in North America
TLDR
The data suggest that population collapse and functional extinction of the megafauna preceded their final extinction by several thousand years and closely preceded enhanced fire regimes and the development of plant communities that have no modern analogs. Expand

Wildfire responses to abrupt climate change in North America
It is widely accepted, based on data from the last few decades and on model simulations, that anthropogenic climate change will cause increased fire activity. However, less attention has been paid toExpand

Ecological Engineering by a Mega-Grazer: White Rhino Impacts on a South African Savanna
TLDR
It is proposed that the White Rhino acts as an influential ecosystem engineer, creating and maintaining short grass swards, which alter habitat for other grazers and change the fire regime. Expand
Evidence for an extraterrestrial impact 12,900 years ago that contributed to the megafaunal extinctions and the Younger Dryas cooling
TLDR
It is proposed that one or more large, low-density ET objects exploded over northern North America, partially destabilizing the Laurentide Ice Sheet and triggering YD cooling, which contributed to end-Pleistocene megafaunal extinctions and adaptive shifts among PaleoAmericans in North America.

DNA from Pre-Clovis Human Coprolites in Oregon, North America
TLDR
It is established that humans were present at Paisley 5 Mile Point Caves, in south-central Oregon, by 12,300 14C years B.P, through the recovery of human mitochondrial DNA from coprolites, directly dated by accelerator mass spectrometry. Expand
