Defaunation in the Anthropocene.
Richard Defauunation stands next to the largest of all moa, Dinornis maximus now D. Another marker for the Anthropocene is the current biodiversity crisis.
The term defaunation was created to designate the declining of top predators and herbivores triggered by human activity, that results in a lack of agents that control the components of the ecosystems vegetation.
Global population declines in mammals and birds From Dirzo et al. Since the industrial revolution, anthropocenr wave of animal and plant extinctions that began with the late Quaternary has accelerated. Calculations suggest that the current rates of extinction are — times above normal, or background levels. Although anthropogenic climate change is playing a growing role, the primary drivers of modern antyropocene seem to be habitat loss, human predation, and introduced species Briggs, The same drivers that contributed to ancient megafaunal and island extinctions.
Defaunation in the Anthropocene
One of the most famous and well-documented extinctions come from Madagascar. Pygmy hippos, giant tortoises, and large lemurs went extinct due to human hunting or tthe disturbance.
A very interesting study by Burney et al. Another well documented case is the Moa extinction in New Zealand. Recent radiocarbon dating and population modeling suggests that their disappearance occurred within years of first human arrival.
Allentoft, Christopher Jacomb, Charlotte L. An extremely low-density human population exterminated New Zealand moa.
