These included shifts in vegetation zones, changes in the hydrology and ecology of lakes and rivers, and fluctuations in the size of mountain glaciers and sandy deserts. Until recently it was thought that such changes were triggered by fluctuations in the distribution of polar ice cover. Now there is increasing recognition that the tropics themselves have 410 0$aBlackwell Quaternary Geoscience Series 606 $aPaleoclimatology$zTropics 606 $aPaleoclimatology$yQuaternary 607 $aTropics$xClimate 615 0$aPaleoclimatology 615 0$aPaleoclimatology 676 $a551.6913 702 $aMetcalfe$b S.
