  • Rodent middens collected from 2350 to 2750 m elevation near Arequipa, provide an 9600-yr vegetation history of the northern Atacama Desert, based on identification of >50 species of plant macrofossils. These midden floras show considerable stability
  • throughout the Holocene, with slightly more mesophytic plant assemblages in the middle Holocene. In the Arequipa area, the midden record does not reflect any effects of a mid-Holocene mega drought proposed from the extreme lowstand of Lake Titicaca, only 200
