We estimated overall and sex-stratified associations between greenspace and CVD mortality rates in Philadelphia, PA, and quantified effect modification of the sex-stratified associations by neighborhood violent crime rates. Sex- and age-stratified census tract CVD mortality rates (years 2008–2015) were linked with proportion tree canopy cover, grass/shrub cover, and total vegetation cover, and proportion of adult residents...AuthorsWanyu Huang, Anneclaire J.

- Remote sensing can provide continuous spatiotemporal information about vegetation to inform wildlife habitat estimates, but these methods are often limited in availability or lack adequate resolution to capture the three-dimensional vegetative details critical for understanding habitat. The Global Ecosystem Dynamics Investigation (GEDI) is a spaceborne light detection and ranging system (LiDAR) that has revolutionized the availability of high-quality three-dimensional vegetation measurements of the Earth’s temperate and tropical forests. To date, wildlife-related applications of GEDI data...AuthorsBrent R. Barry, Joseph D. Holbrook, Jody C. Vogeler, Lisa H. Elliott, Matthew J. Weldy, Damon B. Lesmeister, Clinton Epps, Todd M.

- Biodiversity is declining in many regions of the world. Scientists know more about the diversity of aboveground organisms (like trees, plants, and animals) because they are easier to detect and measure than belowground organisms (like bacteria and fungi). Estimating belowground biodiversity usually involves extracting and sequencing DNA from soil, an expensive process that provides information about a small area of land. Forest restoration efforts would benefit from techniques that provide belowground biodiversity data for large areas of land. In a recent study, researchers explored...AuthorsJenna Zukswert, Ashley Lang, Grant M. DomkeKeywordsSourceFSYear2024
- Tree growth and longevity trade-offs fundamentally shape the terrestrial carbon balance. Yet, we lack a unified understanding of how such trade-offs vary across the world’s forests. By mapping life history traits for a wide range of species across the Americas, we reveal considerable variation in life expectancies from 10 centimeters in diameter (ranging from 1.3 to 3195 years) and show that the pace of life for trees can be accurately classified into four demographic functional types. We found emergent patterns in the strength of trade-offs between growth and longevity across a temperature...AuthorsAgustín Rudas Lleras, Flavio A. M.

- Sagebrush ecosystems across the western U.S. are in decline due to numerous threats, including expansion of coniferous woodlands and forests. The interagency Sagebrush Conservation Design effort recently quantified sagebrush ecological integrity (SEI) to map remaining core sagebrush areas (relatively intact and functional sagebrush ecosystems) and understand spatial and temporal patterns of change relative to primary threats. Recent work has identified conifer expansion as the second leading cause of de- cline in sagebrush ecological integrity biome wide. Here, we sought to create a...AuthorsJason R. Reinhardt, Jeremy D.

- Recent studies have shown numerous Fusarium spp. are associated with symptomatic conifer seedlings in both bareroot and container nursery systems. Some of these species have been found pathogenic to conifer seedlings (e.g., F. avenaceum, F. commune, F. oxysporum, F. solani, and F. verticillioides), but the mechanisms and shared evolutionary history of these conifer pathogenic species have not been well studied in these pathosystems. We compared whole genomes of 17 Fusarium spp. associated with conifer seedlings to elucidate putative shared pathogenicity/virulence gene profiles presumably...AuthorsJohn T.

- Conservation of species’ mobility and ecological integrity is necessary for the productivity of the sagebrush biome in the western United States. Building on the recently developed Sagebrush Conservation Design (SCD) that mapped sagebrush ecological integrity (SEI) - defined as the higher cover of sagebrush and perennial grass and reduced threats due to invasive annual grass, tree encroachment, and human disturbance - we modeled the structural connectivity of sagebrush ecosystems to better incorporate the role of landscape-level processes into assessments of integrity. Because integrity...AuthorsDavid M. Theobald, Alexander V Kumar, Kevin Doherty, Katherine Zeller, Todd B. CrossKeywordsSourceRangeland Ecology and Management. 97: 41-50.Year2024
- Across the western United States, large, severe wildfires in montane forests are creating treeless patches that can fail to reforest naturally due to a lack of seed sources and a warming climate. Nursery-grown tree seedlings are commonly planted by land managers into these areas to promote forest recovery and resilience, but uncertainty exists about what influences their survival across the landscape. We obtained survival monitoring data that had been collected one growing season after planting for 5656 tree seedlings, which were distributed across nine montane wildfires and four National...AuthorsLaura A.

- This poster highlights wildflowers (forbs) common in sagebrush vegetation of the Great Basin. These wildflowers support countless wildlife species, including some species only found in sagebrush ecosystems, such as the greater sage-grouse. Many forb species (including most featured here) are highly valued and used for food, medicine and ceremony by the many Indigenous peoples of the Great Basin. There are hundreds of forb species in sagebrush ecosystems, all with their own unique characteristics. The 31 species on this poster highlight common species potentially useful in restoration....AuthorsStella Copeland, Vanessa Schroeder, Alison Agneray, Sarah C.

- Open burning is commonly used to dispose of piles of forest residues generated by forest management activities; however, this method is associated with smoke emissions and damage to forest soil. Air curtain burners (ACB), such as the Firebox (FB) and CharBoss® (CB), offer an alternative to open burning. This study evaluated the performance of FB for biomass disposal and CB for biomass disposal and biochar production with the objective of quantifying the benefits and limitations of each machine. Ponderosa pine biomass obtained from harvesting after a wildfire event and freshly cut wood from...AuthorsPaul O. Oyier, Han-Sup Han, Dipita Ghosh, Nathaniel Anderson, Deborah S.
