Scientists have spent decades trying to understand how to best promote resilient forests and reduce fuels. A golden endeavor certainly. Is the best approach using a series of prescribed burns? Or is it mechanically cutting trees? Or does the additive effect of both cutting and burning provide the best alchemy?

Greenspaces are increasingly valued for supporting biodiversity in urbanized landscapes. Previous research efforts have emphasized the importance of public land such as parks and nature preserves for biodiversity, yet private yards in residential neighborhoods also have great potential for species conservation. Our study considered the importance of adjacent public and private greenspaces for urban bird diversity. We surveyed birds in public parks (n = 39) and private yards (n = 41) distributed across neighboring twin cities (Champaign and Urbana) in Illinois, USA, to assess potential differen...

Like many other fields, ornithology and birding are addressing their legacy of colonialism, including reexamining their naming practices. Discussions about eponyms, when species are named to honour people, sit at the intersection of nomenclatural stability and social justice concerns. In response to a charged debate about the future of eponymous common names, members of the American Ornithological Society (AOS)'s Diversity and Inclusion Committee held one-on-one listening sessions in 2020 with stakeholder groups across the birding and ornithology community and, in 2021, organized a Community C...

Understanding and controlling the diffusion of ions and chemicals within the secondary plant cell walls are pivotal in various applications of biomasses. Recent studies have shown that inorganic ion diffusion through secondary cell walls is controlled by a moisture-induced glass transition in amorphous polysaccharides, including amorphous cellulose and hemicelluloses. Understanding the diffusion of ions in these structures has been the subject of numerous recent experiments; however, a deep understanding of the underlying mechanisms of interactions between ion atoms and water/hemicellulose mol...

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 ...
