Displaying 21 - 30 of 64,645 Publications- Forests can affect stream structure and function, but evaluations linking freshwater biodiversity to watershed-scale forest-stand conditions are limited. We evaluated competing hypotheses about spatial patterns of freshwater biodiversity by combining species inventories of vertebrates and invertebrates from traditional and environmental DNA (eDNA) methods across 24 temperate watersheds of young to old forests (37 to 124 y old). Freshwater taxonomic and functional richness of invertebrates were, on average, 1.2-fold and 1.5-fold higher, respectively, in older forests (>75 y) than in younger...AuthorsBrooke Penaluna, Ashley A.

- Horizontally continuous fuel types such as pine litter can sustain flame spread along individual fuel particles, but little is known about how wind affects flame behavior at this fine scale.We conducted experiments to examine flame spread rates along thin horizontal fuel particles (cardboard and pine needles) where wind speed and particle orientation relative to wind direction were varied.The wind speed was controlled by mounting a fuel sample on a rotating disk turning at a specified rate.Video measurements showed that flame spread rates on fuel samples varied with fuel orientation angle...AuthorsMark A.

- The ignition of small fuel elements plays a crucial role in fire propagation. These fine fuels are often the first to ignite and serve as a bridge for fire spread to larger scenarios. The moisture content of these fuels significantly affects their flammability and thermal behaviour. In this study, the effect of fuel moisture content (FMC) and orientation on the drying, pyrolysis, ignition, and thermal processes of a cellulose solid fuel is investigated through a series of numerical simulations. In addition, experimental ignition-time measurements were conducted at the U.S. Forest Service...AuthorsAli Edalati-nejad, Sara S. McAllister, Maryam Ghodrat, Jason J.

- Crib fires are a way to produce fires with higher repeatability than generally is the case for wildland and urban scenarios and consequently are used to study fire behavior. Models for simulating large-scale fires benefit from characterization against relevant test conditions. Here we describe a modeling and experimental effort to better explore fire dynamics at the larger range of what is achievable in laboratories. The modeling that corresponds to the tests is used to provide parameters to larger-scale transport modeling efforts for climate effects as well as to evaluate modeling under...AuthorsAlexander L.

- Reducing the consumption of single-use plastics is becoming reality in today’s society. More than 300 million tons of plastic waste are generated annually globally, with a significant portion coming from disposable food packaging. The development of sustainable paper-based packaging coated with biopolymers has gained prominence in the packaging sector due to its biodegradability, non-toxicity and biocompatibility properties. These materials offer additional advantages, such as resistance to moisture and oxidation, which increases the durability of packaged food products. Improving the...AuthorsJulia Cristo Figueiredo, Fernando José Borges Gomes, Ericka Redmond, Caio Moreira Miquelino Eleto Torres, Diana Cubides-Román, Geraldo Ferreira David, Biljana Bujanovic, Roberto Carlos Costa LelisSourceFloresta e AmbienteYear2026
- The effects of climate warming on phenological patterns and species distributions have been described for many species but understanding how changes in behavior and demography lead to these shifts is less understood. We followed a population of the common frog, Eleutherodactylus coqui, as part of an in-situ field warming experiment (Tropical Responses to Altered Climate Experiment; TRACE), in a humid tropical forest using capture-markrecapture methods. We assessed how growth, body size, and survival varied by warming treatment, sex, and developmental stage of frogs. In warmed plots (+4◦C...AuthorsT.J.Hawley Matlaga, P.A. Burrowes, J.E.

- This study aimed to assess the technical feasibility and economic viability of cellulose nanocrystals produced from a marine animal, i.e., tunicate. An industrial-scale process simulation model was developed with a 50 tonne/day production capacity of tunicate-based cellulose nanocrystals, at 1% solid. The system boundary included preprocessing and pretreatment of raw tunicate, acid hydrolysis, filtration, and concentration. The minimum selling price of tunicate-based cellulose nanocrystals (1% solids) in the baseline scenario was estimated to be $1.16/kg, and it could be reduced to...AuthorsSeyed Hashem Mousavi Avval, Naveenkumar Rajendiran, Matthew J.

Hurricane Fiona in Puerto Rico: assessing effects and adaptive responses in agriculture and forestry
Hurricanes pose risks for agriculture and forestry in regions where successive storms contribute to cumulative effects that hinder recovery and reduce adaptive capacity. Hurricanes also provide learning opportunities, and successive hurricanes provide opportunity to evaluate whether lessons have been applied and if they reduce the negative effects or improve recovery times. In Puerto Rico, hurricane Fiona made landfall on September 18, 2022, while many communities and landscapes were still facing the longstanding impacts of hurricanes Irma and María, major hurricanes of 2017. This study...AuthorsNora Alvarez-Berrios, Kathleen McGinley, Paloma S. Rodríguez-Serrano, Luis Alexis Rodríguez-Cruz, William A. GouldKeywordsSourceFrontiers in Sustainable Food SystemsYear2026- Biodiversity generally enhances ecosystem productivity, but whether such effects persist or intensify during climate extremes is unclear. Here we synthesized data from 75 biodiversity experiments across grasslands and forests to assess how aridity and soil nutrients modulate plant diversity effects under drought and heat extremes. Biodiversity most strongly enhanced productivity under extreme drought in more arid grasslands but had limited effects in forests under such conditions. More arid grasslands showed enhanced complementarity effects under extreme drought, whereas less arid grassland...AuthorsTakehiro Sasaki, Daniela Hoss, Yuanyuan Huang, Yuki Iwachido, Liting Zheng, Luis Abdala-Roberts, Eric Allan, Harald Auge, Nadia Barsoum, Jürgen Bauhus, Christel Baum, Carl Beierkuhnlein, Friderike Beyer, Pedro Brancalion, Seraina L.

- Wildfires have increasingly affected human and natural systems across the western United States (WUS) in recent decades. Given that the majority of ignitions are human‐caused and potentially preventable, improving the ability to predict fire occurrence is critical for effective wildfire prevention and risk mitigation. We used over 500,000 wildfire ignition records from 2000 to 2020 to develop machine learning models that predict daily ignition probability across the WUS and incorporate a wide range of physical, biological, social, and administrative variables. A key innovation of this work...AuthorsYavar Pourmohamad, John T. Abatzoglou, Erica Fleishman, Erin J. Belval, Karen C.
