AbstractInvestigation of snail-bearing alluvium from the Smyth Crossing site in Uvalde County, Texas, indicates that the terrestrial gastropod fauna of this area has been stable for at least 3000 yr. However, relative proportions and presence/absence variations indicate changes in the relative occurrence of preferred microhabitats of certain snails. Gastropods from an excavated soil column reveal a succession of gastropod associations in response to succession of the plant community of the site from a riverside gravel bar to an upland savannah/grassland. Human impact on the gastropods is mostly contemporary, with apparent local extirpations of some species having occurred. The recovered paleofaunas provide no evidence for regional climatic change since 3000 yr B.P.

AbstractSediments began accumulating in nine mires on Barrington Tops, on the Northern Tablelands of New South Wales, before 11,000 yr B.P., and peat became common in the region by 8600 yr B.P. Sedimentation rates were low, but increased markedly about 3000 yr B.P. and again around 500 yr B.P. as a result of regional climatic change. A comparison of the results with other environmental data from the region suggests that conditions in the early Holocene were warmer and moister than at present, but that cooler and drier environments developed about 3000 yr B.P. In the last 500 yr a slight warming and either increased precipitation or cloudiness has become evident.
