- carbon monitoring to fire risk analysis or habitat and biodiversity assessments. Ground-based LiDAR technologies, such as terrestrial (TLS) and mobile (MLS) laser scanning, enable precise 3D mapping of trees, understorey, and ground, offering rich structural detail. Yet, extracting meaning from these dense, unstructured point clouds remains a persistent challenge that requires reliable and scalable segmentation methods. Earlier segmentation approaches have struggled to generalize across diverse forest types and acquisition conditions. Recent advances in deep learning (DL), particularly...AuthorsDiego Laino, Carlos Cabo, Romain Janvier, Celestino Ordonez, Rodolfo Bolanos, Stefan H. Doerr, Andrew T.

- Severe wildfires often increase inputs of nitrogen (N) and phosphorus (P) to streams, which can alter nutrient limitation and primary production of benthic algae. Changes in nutrient limitation, however, vary over space and time due to physical and biological factors. In particular, the low gradient, wide valley‐bottom segments of montane rivers (hereafter ‘beads’) are zones of nutrient uptake and retention. Few studies, however, have evaluated the role of river beads in mediating algal nutrient limitation following wildfire in perennial streams.We hypothesized that river beads would act...AuthorsAlyssa M.

- Snowmelt is a dominant hydrologic process in mountainous watersheds and western river systems, yet automatic logging of snowpack properties such as depth, density, and internal energy fluxes, especially during melt, is not done at many Rocky Mountain surface flux sites. In this study, we show that springtime variations in the surface energy budget imbalance can be used to estimate snowpack energy fluxes. Using observations from the US‐GLE AmeriFlux site, we demonstrate a data‐driven method to extract springtime energy budget anomalies and show that 83% of this anomaly is explained by the...AuthorsAlexander S.

- Wetlands comprise only 5–8% of land surface but hold 20–30% of estimated soil carbon globally. However, wetlands are also significant sources of greenhouse gases such as methane ( CH4) and nitrous oxide ( N2O). Disturbances such as wildfires can alter the balance between carbon storage and greenhouse gas production in wetland systems; therefore, it is crucial to understand wetland response and recovery after wildfires. While wildfires are known to significantly impact ecosystem function through changes in soil properties, nutrient cycling, and hydrology, subalpine wetlands remain understudi...AuthorsPranjal Dwivedi, Holly K.

- Although soil burn severity (SBS) is traditionally mapped post-fire, pre-fire predictive approaches remain limited despite their potential to identify areas at risk of soil degradation, runoff and erosion.To develop a large-scale model for predicting post-fire SBS from pre-fire conditions at ~30 m spatial resolution.A harmonized dataset of 62 wildfires (2018–2024) was used to build machine learning (ML) frameworks based on Random Forest, eXtreme Gradient Boosting (XGBoost), and Light Gradient Boosting Machine (LightGBM), using pre-fire vegetation, climate, soil–terrain and anthropogenic...AuthorsSubhankar Das, Mariana Dobre, Roger Lew, Sarah A.

- Belowground functional diversity is relevant to numerous ecosystem functions and to ecosystem resilience under global change, yet quantitative information on belowground plant traits is disparate and poorly integrated across fields of research. So far, belowground plant traits have been studied in three disparate research domains: (i) fine root traits in the context of belowground resource economics and symbioses; (ii) maximum rooting depth and lateral extent of the root system in the context of overall plant allometry and resource uptake; (iii) clonal organs and bud banks with a focus on...AuthorsHelge Bruelheide, Karl Andraczek, Aline B.

- Climate change and shifting fire regimes have the potential to alter forest structure and tree growth dynamics in high‐elevation forests; however, the relative role of competitive and facilitative interactions in shaping postfire responses remains unclear. To investigate these dynamics, we studied tree growth across an elevational gradient in the subalpine and treeline forests of the Selway‐Bitterroot Wilderness (Idaho and Montana, USA), where fire atlas data and a history of limited fire suppression enabled the implementation of a 2 × 2 factorial study design. We sampled burned and...AuthorsJosh Beisel, Alina Cansler, Sean A. Parks, David L. R. Affleck, Ashley P. Ballantyne, Andrew J. LarsonKeywordsSourceEcosphereYear2026
- Climate change is reducing winter snowpack and advancing spring snowmelt across the western United States, interacting with El Niño–Southern Oscillation (ENSO) teleconnections that drive spatially predictable interannual fluctuations that contribute to high- or low-snow winters. Early snowmelt extends the fire season, enhancing opportunities for ignition and increasing fuel dryness, both of which contribute to greater burned areas. However, relationships between snowpack on burn severity, a measure of forest loss and expected biogeochemical and hydrological impacts of fire, have not been...AuthorsJared A Balik, Jonathan D Coop, Sean A.

- Forest persistence amid shifting climate conditions requires sufficient tree recruitment for sustaining populations. In dryland ecosystems where precipitation can be episodic and variable, changes in precipitation pulse regimes may be critically important for seedling establishment, as some populations may be locally adapted to variable resource availability. We conducted a greenhouse common garden experiment to evaluate Pinus monophylla seedling responses to varying watering pulse regimes. We used seeds from four sites representing endpoints of range-wide gradients of climatic water...AuthorsJeremy S Adkins, Alexandra K.

- Climate change is impacting freshwater ecosystems, which contain many species already threatened by anthropogenic activities. To help managers protect imperiled species, we developed a framework for assessing the potential for aquatic refugia within the state of New Mexico, U.S.A. We used literature review and stategenerated lists of sensitive species and habitats to develop five taxa-specific habitat groups as targets for assessment (cold-water fish habitat, perennial streams, perennial water amphibian and reptile habitat, ephemeral catchments, and springs). We then selected sets of...AuthorsD. Max Smith, Megan M. Friggens, Karen C. ChaudhryKeywordsSourceEcological IndicatorsYear2026
