Non-native- dominated landscapes may arise from invasion by competitive plant species, disturbance and invasion of early-colonizing species, or some combination of these. Without knowing site history, however, it is difficult to predict how native or non-native communities will reassemble after disturbance events. Given increasing disturbance levels across anthropogenically impacted landscapes, predictive understanding of these patterns is important. We asked how disturbance affected community assembly in six invaded habitat types common in dryland, grazed landscapes on Island of Hawai‘i. We m...

Changing fire regimes have the potential to threaten wildlife populations and communities. Understanding species’ responses to novel fire regimes is critical to formulating effective management and conservation strategies in an era of rapid change. Here, we examined the empirical effects of recent and historical wildfire activity on Mexican spotted owl (Strix occidentalis lucida) populations in the southwestern United States. Using region-wide, standardized detection/ non-detection data of Mexican spotted owl breeding pairs collected from 2015 to 2022, we found (i) higher rates of pair occupan...

Wildfire size and severity have increased in recent decades prompting scientists to take a closer look at where fire refugia - forested locations that are burned less frequently or severely than their surroundings - occur on a given landscape. Recently published research to identify potential refugia across upland conifer forests sheds light on the factors that influence where tree survival and recruitment are likely.

The TreeMap dataset provides detailed spatial information on forest characteristics, including number of live and dead trees, biomass, and carbon across the entire forested extent of the continental United States. The objective of TreeMap is to combine the complementary strengths of detailed-but-spatially-sparse Forest Inventory and Analysis (FIA) data with less-detailed-but-spatially-comprehensive LANDFIRE data to better estimate forest characteristics at a variety of scales.

Volatile products from thermal decomposition of lignocellulosic biomass have been well characterized, but the solid- and liquid-phase reactions during the early stages of decomposition are largely unknown. Here the initial solid-phase biomass thermal deconstruction reactions were analyzed in situ and with high particle heating rates, delineating how these processes occur. A variety of instrumentation was used to quantify the extent and relative rates of deconstruction, demonstrating that biopolymers resist the thermally energetic conditions to differing degrees, even when ensconced in biomass ...

The demise of enemy release associated with the invasion of specialist folivores on an invasive tree
There is a long history of humans either intentionally or accidentally moving plant species to areas outside of their native ranges. In novel environments, populations of many of these plant species exhibit explosive population growth and spread, in part due to the absence of coevolved enemies such as herbivorous insects. However, over time such enemies can ‘catch up’ with their host and re-establish host–herbivore relationships. Though this phenomenon has been documented in several systems, little evidence exists on how this re-assembly of enemies results in increased levels of herbivory. In ...

Currently, no multiple century fire scar records have been constructed in the Lower Peninsula of Michigan, USA, a region where historical vegetation ranged from prairies and oak-dominated woodlands in the south to conifernorthern hardwood forests and swamps to the north. The western portion of the Huron-Manistee National Forests is located within this strong vegetation transition (i.e., "Tension Zone") and, based on this study, has well-preserved remnant red pine trees dating back to at least the late 1400s with fire scars dating back to 1523. From fire scar records constructed at four study s...

Neighborhoods are one of the key determinants of health disparities among young people in the United States. While neighborhood deprivation can exacerbate health disparities, amenities such as quality parks and greenspace can support adolescent health. Existing conceptual frameworks of greeninghealth largely focus on greenspace exposures, rather than greening interventions. In this paper, we develop and propose a Greening Theory of Change that explains how greening initiatives might affect adolescent health in deprived neighborhoods. The theory situates greening activities and possible mechani...

A forest investment’s returns are generated from three sources: the land’s gain in value, the timber’s growth in size and product class improvement, and the timber price change. Land appreciation is rapidly leading to an inverse relationship with tenure. This phenomenon has turned what was once an academic exercise of land appraisal into a practical one that incorporates the asset’s terminal value. We found that failing to account for the terminal value can lead to sizable differences in forest value, although those differences diminish with increasing planning time horizons. The findings can ...
