How was life on the Gulf Coast affected by global climate changes and rising sea levels during the Classic period?

Residents of the site of Aguacatal (excavated by Ray Matheny of Brigham Young University) enjoyed an abundance of resources from the ocean, its shorelines, and the inland freshwater and terrestrial environs on which the site was located. During their residency however, global climate changes combined with their own impacts on their local environment to change the resource-base on which they relied for their subsistence and economy. Our work is to determine exactly what changes took place (using the animal remains to chart sea level rise, the effects of gradual dessication on riverine resources, and the impact of human fishing and hunting on their resources) and how the residents of the site reacted to those changes.
