The Anthropocene: conceptual and historical perspectives.
The human imprint on the global environment has now become so large and active that it rivals some of the great forces of Nature in its impact on the functioning of the Earth system. Although global-scale human influence on the environment has been recognized since the 1800s, the term Anthropocene, introduced about a decade ago, has only recently become widely, but informally, used in the globa...
متن کاملReconciling conflicting perspectives for biodiversity conservation in the Anthropocene
© The Ecological Society of America www.frontiersinecology.org H environmental impacts are now so extensive and pervasive that many consider that the planet has entered a new geological epoch – the Anthropocene. Increasingly, efforts to conserve biodiversity are confronted with new challenges resulting from profound changes to many biotic and abiotic processes (Steffen et al. 2004; MA 2005), wh...
متن کاملGeobiology of the Anthropocene
Homo sapiens first appeared on the Earth somewhere in Africa roughly 200 000 years ago. It happened with little fanfare; few could have imagined that this new species of primate would someday disrupt the Earth system to the point of defining a new geologic epoch around its legacy. Indeed, the first 150 000 years of the natural history of our species, mostly in Africa, were fairly uneventful for...
متن کاملMegafauna and ecosystem function from the Pleistocene to the Anthropocene.
Large herbivores and carnivores (the megafauna) have been in a state of decline and extinction since the Late Pleistocene, both on land and more recently in the oceans. Much has been written on the timing and causes of these declines, but only recently has scientific attention focused on the consequences of these declines for ecosystem function. Here, we review progress in our understanding of ...
متن کاملStratigraphy of the Anthropocene.
The Anthropocene, an informal term used to signal the impact of collective human activity on biological, physical and chemical processes on the Earth system, is assessed using stratigraphic criteria. It is complex in time, space and process, and may be considered in terms of the scale, relative timing, duration and novelty of its various phenomena. The lithostratigraphic signal includes both di...
