Track: Dendroecology
Xylogenesis can provide valuable insight into the causal link between wood production, phenological traits of trees, and environment by gathering specific and detailed information like (1) the onset or (2) ending of cambial activity and xylem cell differentiation, (3) changes in cell number, size and shape, and (4) rates of change of the processes. The variability in the growth timings and dynamic ... More

We developed a fire history of a portion of the Boundary Waters Cane Area Wilderness in northern Minnesota, USA using more than 70 remnant Pinus resinosa stumps collected within an historic canoe travel corridor in Lac La Croix. Our search builds on the efforts of Heinselman to better understand the relative influence of climate and Ojibwe occupancy patterns on the area’s fire regime. Crossdate ... More

The invasion of European earthworms into North American temperate forests is profoundly and fundamentally changing the dynamics of these ecosystems. Immediately upon invasion, forest soils are compacted, native plant communities are reduced in diversity and abundance, the fine root systems of trees and their associated mycorrhizal communities are disrupted, carbon fluxes increase, nitrogen is mine ...

We examined the surface fire regime in a ponderosa pine-dominated forest on the Hualapai tribal lands in Arizona. Using 113 fire-scarred trees from five 25-ha sites, we inferred spatio-temporal attributes and regulators of the fire regime over three land-use periods (historical, suppression, modern) between 1702 and 2007. Fire frequency and synchroneity patterns were similar, but fire seasonality ... More

In humid, broadleaf forests, gap-dynamics are thought to be the prevailing disturbance regime. Paleoecology, however, shows regional-scale changes forest alteration with climatic change. We used 76 tree-ring collections and 5.3k tree recruitment dates to investigate the potential for regional-scale disturbance in a temperate, humid forest. Growth-release analysis indicates coherent and intense can ... More
