What is it about?
Ostracodes (Crustacea) and mollusks are important component of wetland environments. Both groups respond to changes in water chemistry, temperature and salinity. Species replacement based on their known ecological preferences makes them powerful tools to understand wet-dry cycles that characterized the late Pleistocene-early Holocene.

Why is it important?
Identification of environmental change in the Southern High Plains is crucial to understand the movements of Clovis, Folsom and other Paleoindian people in the American Southwest. In this study we propose the evolution from wetter/cooler to warmer/drier conditions at Mockingbird Gap site and its response to climate change and groundwater fluctuations during and after the Younger Dryas Chronozone.
Perspectives
It has been a great pleasure co-authoring this paper with Vance. I, personally, benefited from his expertise on the region's geomorphology and climate history. I hope this investigation on the evolution of climate in the American Southwest at the end of the Pleistocene generates good feedback to improve our understanding of the human-environment interaction.
