I was recently published in the Holocene and wanted to share my work.

Abstract:

Climatic fluctuations that occurred in North Africa during the early and middle Holocene had a profound impact on the environment of the region and would have required human populations in the area to adapt their subsistence and economic strategies in equally significant ways. Capsian groups, located in eastern Algeria and southern Tunisia from approximately 10,000 to 6000 cal. BP, were among the last North African foragers at a time when other groups were abandoning food collection to engage in food production in the form of pastoralism. Capsian foragers relied heavily on land snails, but we have little information on their use of plant resources, which can be an important indicator of economic adaptation to environmental change. In this study we use phytolith analyses at the Capsian site of Aïn Misteheyia in eastern Algeria to track the changes in subsistence strategies throughout much of the middle-Holocene climatic transitions. Our results show that Capsian foragers exploited plants such as sedges and small-seeded grasses from wetland microenvironments within their home ranges which allowed them to demonstrate robust and resilient resource procurement strategies, and maintain a foraging lifestyle resistant to major fluctuations in climate.

I came across this interesting article from the Department of Interior news, published in the Federal Register. It includes the proposed revision of Critical Habitat for the Comal Springs Dryopid Beetle, Comal Springs Riffle Beetle, and Peck’s Cave Amphipod. Click here to read the article.
