- ... There is significant spatial and temporal variability associated with greenhouse gas (GHG) fluxes in high-latitude Arctic tundra environments. The objectives of this study are to investigate temporal variability in CO2 and CH4 fluxes at Barrow, AK and to determine the factors causing this variability using a novel entropy-based classification scheme. In particular, we analyzed which geomorphic, so ...

- ... Analyzing how humans interacted with (and within) their greater ecosystems facilitates a more nuanced understanding of past lifeways. In this aim, we use food web modeling to reconstruct the biotic environment of Ancestral Pueblo people living in the central Mesa Verde region between A.D. 750 and A.D. 1300. This framework enables an investigation into the effects of species introductions and remov ...
