Global integrative assessment of extinction. Split globe into zines: map extinction. Nice global pie chart of degree of megafaunal abundance and extinction worldwide.
Model suggests that human arrival is the biggest factor. Climate is 1/4 to 1/3 of megafaunal extinction.
Geographically specific examples:
Europe: early human arrival caused some extinction early , climate change a major influence at end of ice age
Madagascar, New Zealand, Tasmania humans explain most of extinction
North and South America: similar patterns to small islands, with humans biggest factor and climate a minor factor.
Indo-Malaya and Central Asia: the model fails. It predicts extinctions that do not occur. Not clear why Asia is different.
The models strongly implicate human colonisation. Central and Southern Asia is the next frontier - we cannot explain relatively low levels of extinction there.
