New PalEON Papers

Jackie has co-authored two recent papers published in PLoS One and Global Change Biology through her collaboration on the PalEON Project.

Our findings presented in Goring, et. al., “Novel and Lost Forests in the Upper Midwestern United States,” in PLoS One demonstrate that modern forests in the Upper Midwest are more homogenous (spatially and structurally uniform) and ecotone gradients are more diffuse than pre-European settlement forests. This analysis was developed from historical tree data that was part of the 19th century public land survey system (PLSS).

In Rollinson, et. al., “Emergent climate and CO2 sensitivities of net primary productivity (NPP) in ecosystem models do not agree with empirical data in temperate forests of eastern North America” in press at Global Change Biology, we showed that models are unable to reproduce the sensitivity between NPP and climate and CO2 concentrations that are found within tree ring records. The biggest driver of uncertainty for the sensitivity of modeled NPP was the response to CO2 concentration, which points to the potential for experiments in tree ecophysiology to inform and improve models.
