MAMMALIAN SPECIES ABUNDANCES AS CLIMATIC INDICATORS IN HALL’S CAVE, TEXAS
We applied these correlations from modern ecosystems to late Pleistocene through Holocene assemblages of mammals from Halls Cave, Kerr County, Texas. Caves found on the Edwards Plateau provide a great deal of information on the Quaternary mammals of Texas, but Halls Cave is unique because it provides a nearly continuous record of the Holocene. This cave is stratified and extensively AMS carbon dated. To accurately test whether species numbers can provide paleoclimate data, an independent climate signal is needed. We utilized a combination of climate signals to eliminate potential biases associated with each method. Climate data were taken from previously established pollen records, stable isotopes, and climate models. We began by studying the Holocene because the climate and mammals should be most similar to today. The larger goal of this project is to determine the temporal limits and applicability of this method to paleoecology.
