Rea, D. K. and Leinen, M., 1988. Asian aridity and the zonal westerlies: Late Pleistocene and Holocene record of eolian deposition in the northwest Pacific Ocean. Palaeogeogr., Palaeoclimatol., Palaeoecol., 66:1 8. A 30,000-year record of eolian deposition in the northwestern Pacific Ocean provides a history of the aridity of the Asian source region and information on the changing latitude and ...

Abstract. The French Upper Rhine alluvial plain is characterized by a complex system of paleochannels inherited from Late Glacial to Holocene fluvial dynamics the and Ill river systems, among other smaller rivers. These represent valuable archives for understanding reconstructing landscape evolution area. However, temporal trajectories paleochannels, in response range environmental changes, rem...

A multi-proxy analyses was applied on the sediment core from Gulf of Saros (GoS) to identify and characterize climate hydrological changes during middle-to-late Holocene. The formation two discrete Holocene sapropel layers in GoS sediments documented for first time based total organic carbon analysis. According our paleo-proxy records, lower deposited under warm humid conditions that gave rise ...

The sediments of the Playa Lake are sensitive indicators of local climates that any change in climate, hydrology, and sedimentary environment will cause changes in the physical and chemical properties of the sediments. These sediments create a valuable and important archive with high resolution to examine these changes in the past. One method of studying climate change during quaternary and oft...

Hypnomys is a genus of Gliridae (Rodentia) that occurred in the Balearic Islands until Late Holocene. Recent finding of a complete skeleton of the chronospecies H. morpheus (Late Pleistocene-Early Holocene) and two articulated skeletons of H. cf. onicensis (Late Pliocene) allowed the inference of body size and the calculation of several postcranial indexes. We also performed a Factorial Discrim...

We are pleased that the publication of our recent study (1) has stimulated further discussion of the complexities of past human– vegetation–climate interactions in the Neotropics, and that Silva (2) considers that our study “fundamentally changes our understanding of the magnitude and nature of pre-Columbian land use in the Amazon region.”However, we wish to address several of the points raised...

Indigenous land use and climate have shaped fire regimes in southeast Australia during the Holocene, although their relative influence remains unclear. The archaeologically attested mid-Holocene decline land-use intensity on Furneaux Group islands (FGI) to mainland Tasmanian SE presents a natural experiment identify roles of anthropogenic use. We reconstruct two key facets regional regimes, bio...

Future precipitation levels remain uncertain because climate models have struggled to reproduce observed variations in temperature-precipitation correlations. Our analyses of Holocene proxy-based correlations and hydrological sensitivities from 2237 Northern Hemisphere extratropical pollen records reveal a significant latitudinal dependence temporal among the early, middle, late Holocene. These...

Modern complex societies exhibit marked resilience to interannual-to- decadal droughts, but cultural responses to multidecadal-to-multicentury droughts can only be addressed by integrating detailed archaeological and paleoclimatic records. Four case studies drawn from New and Old World civilizations document societal responses to prolonged drought, including population dislocations, urban aband...
