The mammoth, an extinct genus of megafauna.
The mammoth, an extinct genus of megafauna.

Megafauna are generally defined as animals that weigh over 500 kg to 1 tonne, i.e., any animal larger than the largest widespread domestic animal, the domestic bull. Some authors use much lower thresholds, even as low as 50 kg (making humans a megafauna species), but they are not widely accepted. The term is also used to refer to particular groups of large animals, both to extant species and, more often, those that have become extinct in geologically recent times.

Megafauna animals are generally K-strategists, with great longevity, slow population growth rates, low death rates, and few or no natural predators capable of killing adults. These characteristics make megafauna highly vulnerable to human exploitation. Many species of megafauna have become extinct within the last million years, and, although some biologists dispute it, human hunting is often cited as the cause. In ecology, r/K selection theory relates to the selection of traits (in organisms) that allow success in particular environments. ... Hunter and Huntress redirect here. ...

Usage

The tense in which the term is used is usually apparent from the context:

  1. A particular group of large, extinct animals. For example, American megafauna, meaning "the various species of large American mammal that became extinct about 13,000 years ago".
  2. Any group of large animals. For example, South American megafauna, meaning "all large animals in South America today".

Extinction

Two major hypotheses have been proposed to explain the extinction of megafauna. The first cites human intervention, noting that the arrival of humans to various continents coincided with the extinction of that continent's megafauna. Two main arguments are used in opposition to this hypothesis, namely the coexistance of humans and megaufauna in France, regardless of heavy predation, and the decline of megafauna in North America began before human arrival.[citation needed] There is also a distinct lack of large kill sites in the archaeological record.[citation needed]


The second main hypothesis uses climate change, most notable large increases in average temperature, as the major factor in the death of megafauna. However, the woolly mammoth survived on at least two islands in the region of the Bering Strait for thousands of years after the end of the last glaciation 12,000 years ago. This is indicative that it was not just a change in climate and accompanying vegetation that killed off megafauna in other regions, but that the replacement of other species more optimally adapted for the conditions that came with the end of the Pleistocene caused significant population duress.

New evidence suggests that humans were the ultimate cause of the extinction of megafauna in Australia. At the time of extinction, arid regional climate was immensely similar climates of today. The megafauna were hence strongly adapted to an such a climate, ruling out climate change as a cause of extinction. Evidence indicates that all forms of megafauna became extinct in the same rapid timeframe, approximately 47,000 years ago, in which humans entered the region. The main mechanism contributing towards extinction is thus implied to be human burning of a much less fire-adapted landscape than that of today. Isotopes from teeth indicate such burning caused drastic changes in vegetation and hence in the diet of surviving species, as well as the loss of megafaunal species. [1] [2] [3].
