The role of tree functional strategies is pivotal in regulating forest fitness and their ability to cope with water stress. However, how the functional strategies found at the tree or species level scale up to characterise forest communities and their variation across regions is not yet well-established. By combining eight water-stress-related functional traits with forest inventory data from the USA and Europe, we investigated the community-level trait coordination...AuthorsDaijun Liu, Adriane Esquivel-Muelbert, Nezha Acil, Julen Astigarraga, Emil Cienciala, Jonas Fridman, Georges Kunstler, Thomas J.

- Deadwood represents a significant carbon pool and unique biodiversity reservoir in forests and savannas but has been largely overlooked until recently. Storage and release of carbon from deadwood is controlled by interacting decomposition drivers including biotic consumers (animals and microbes) and abiotic factors (water, fire, sunlight, and freeze–thaw). Although previous research has focused mainly on forests, we synthesize deadwood studies across diverse ecosystems with woody vegetation. As changing climates and land-use practices alter the landscape, we expect accelerating but...AuthorsBaptiste J. Wijas, Steven D. Allison, Amy T. Austin, William K. Cornwell, J. Hans C.

- Purpose of Review The objective quantification of stand density (SD) is necessary for predicting forest dynamics over space and time. Despite the development of various synthetic representations of SD, consensus remains elusive regarding a primary integrated measure due to contrasting data sources, statistical modeling methods, and distinct regional variations in forest structure and composition. One of the most enduring and robust measures of SD is Reineke’s (1933; J. Ag Res. 46, 627-638) stand density index (SDI), which has long formed the basis for the prediction of stand development...AuthorsEmmerson Chivhenge, David G. Ray, Aaron R. Weiskittel, Christopher W.

- Tree regeneration shapes forest carbon dynamics by determining long-term forest composition and structure, which suggests that threats to natural regeneration may diminish the capacity of forests to replace live tree carbon transferred to the atmosphere or other pools through tree mortality. Yet, the potential implications of tree regeneration patterns for future carbon dynamics have been sparsely studied. We used forest inventory plots to investigate whether the composition of existing tree regeneration is consistent with aboveground carbon stock loss, replacement, or gain for forests...AuthorsLucas B.

- Uncrewed aerial system (UAS) structure from motion (SfM) monitoring strategies for individual trees has rapidly expanded in the early 21st century. It has become common for studies to report accuracies for individual tree heights and DBH, along with stand density metrics. This study evaluates individual tree detection and stand basal area accuracy and precision in five ponderosa pine sites against the range of SfM parameters in the Agisoft Metashape, Pix4DMapper, and OpenDroneMap algorithms. The study is designed to frame UAS-SfM individual tree monitoring accuracy in the context of data...AuthorsWade Tinkham, George A. WoolseyKeywordsSourceRemote Sensing. 16: 3844.Year2024
- The American elm (Ulmus americana L.), once a dominant species in North American floodplain forests, has suffered significant population declines due to Dutch elm disease (DED). Despite this, some elms persist, potentially exhibiting disease resistance and climate-adaptive traits that could facilitate restoration. Understanding these traits is crucial for selecting genotypes suited to current and future climatic conditions, particularly in colder regions. This study evaluated the mid-winter cold tolerance of American elm genotypes across a climatic gradient to ascertain evidence of local...AuthorsJohn Butnor, Cornelia Wilson, Melike Bakır, Anthony W.

- Few studies have explored variability of associations between greenspace and cardiovascular (CVD) mortality according to demographic or neighborhood contextual factors. 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.
