    ### Access Dataset can be accessed and downloaded from the directory via: [http://arcticdata.io/data/10.18739/A2599Z39H](http://arcticdata.io/data/10.18739/A2599Z39H). ### Overview This dataset contains raw sedimentary ancient DNA (sedaDNA) sequence data and associated metadata generated from a 3-meter sediment core collected from Andy Lake, Alaska. The core was obtained during fieldwork supported by the National Science Foundation (NSF) Arctic Doctoral Dissertation Research Improvement Grant #2230019, titled Assessing the impacts of Pleistocene megaherbivores on vegetation stability and resilience in the Arctic, awarded to Principal Investigator (PI) Jacquelyn L. Gill and Co-PI Alessandro Mereghetti. The primary objective of this project is to investigate how Pleistocene megafaunal diversity influenced long-term plant community dynamics and ecosystem resilience in Arctic environments. These data contribute to understanding ecological baselines and biotic responses to past climate and extinction events, with implications for modern conservation and rewilding strategies.
