Displaying 1 - 10 of 63,146 Publications- Technology for the acoustic detection of animals has advanced rapidly over the past few decades. Due to ease of use, consistency, and safety, acoustic methods are particularly useful for science applications that engage the public. In this study, we evaluated the technological and educational trade-offs between 2 acoustic bat detectors in a participatory science application along the Colorado River in the Grand Canyon, Arizona. Both devices were deployed simultaneously by commercial river guides in parallel with sampling insect prey for 1 h at dusk on 48 dates between April and October 2022.

To diversify or not to diversify: a preliminary report on farmers’ perspectives on diversification in the U.S. Midwest
Formally Refereed
Diversifying the simplified landscape of corn and soybeans in the Midwest is an emerging priority in both the public and private sectors to reap a suite of climate, social, agronomic, and economic benefits. However, little research has documented the perspectives of farmers, the primary stakeholders in diversification efforts. This preliminary report uses newly collected survey data (n = 725) from farmers in the states of Illinois, Indiana, and Iowa to provide descriptive statistics and tests to understand what farmers in the region think about agricultural diversification, including their per...AuthorsLauren Asprooth, J.

ProkopyKeywordsSourceRenewable Agriculture and Food SystemsYear2025- Silvopasture is the practice of managing desired woody perennials, forages, and livestock on the same unit of land. Silvopasture systems can be applied in many settings, including vineyards. In vineyard silvopasture systems, vines are the perennial component and small livestock are grazed in the alleys between vine rows. While grapevines are not trees, they are woody perennials that provide some of the same functions as trees in silvopasture systems. Like trees, grapevines can be intentionally integrated with other components into a single system to generate benefits for both growers and for t...AuthorsKatherine FavorYear2025
- Windbreaks and hedgerows are two types of conservation buffers that can provide benefits to vineyards and the surrounding landscape. Windbreaks are rows of trees and/or shrubs in linear configurations, often established with the goal of slowing wind. Hedgerows are dense groupings of trees, shrubs, and other plants in a linear design, planted to achieve a natural resource conservation purpose such as providing habitat for wildlife, including pollinators and beneficial natural enemies. Hedgerows and windbreaks are structurally similar and perform many of the same functions. For example, many win...AuthorsKatherine FavorSourceAgroforestry Note 52.

Going slow to go fast: Landscape designs to achieve multiple benefits
Formally Refereed
Introduction: Growing concerns about fire across the western United States, and commensurate emphasis on treating expansive areas over the next 2 decades, have created a need to develop tools for managers to assess management benefits and impacts across spatial scales. We modeled outcomes associated with two common forest management objectives: fire risk reduction (fire), and enhancing multiple resource benefits (ecosystem resilience). Method: We evaluated the compatibility of these two objectives across ca. 1-million ha in the central Sierra Nevada, California. The fire strategy focused on s...AuthorsPatricia N.

DaySourceFrontiers in Environmental Science. 13: 1560125.Year2025- Silvopasture is increasingly recognized as a nature-based solution to climate change. However, few studies have quantified the total carbon storage potential of silvopasture in humid continental climates, complicating efforts to understand climate mitigation potential. In this study, we compared the carbon stocks of silvopastures established by afforestation of trees into pastures (silvopasture) with pasture that remained without trees (treeless pasture) on five farms in the Northeastern United States. Total carbon content was measured in the woody, herbaceous, and soil pools for silvopastures...AuthorsJoseph Orefice, Matthew M. Smith, William C.

- Hardworking bees are a familiar sight outdoors as they forage for nectar and pollinate flowers. Along with nectar, both wild bees and honey bees collect pollen to bring back to brooding areas, where it feeds developing larvae. From the bee’s perspective, an important question arises: is all pollen nutritionally the same and, if not, how do bees get the nutrients they need?AuthorsSue Miller, Anthony Vaudo, Bryce Richardson, Sarah Barga, Justin RunyonKeywordsSourceScience You Can Use Bulletin, Issue 72.

A cellular necrosis process model for estimating conifer crown scorch
Formally Refereed
Fire-caused tree mortality has major impacts on forest ecosystems. One primary cause of post-fire tree mortality in non-resprouting species is crown scorch, the percentage of foliage in a crown that is killed by heat. Despite its importance, the heat required to kill foliage is not well-understood. We used the “lag” model to describe time- and temperature-dependent leaf cell necrosis as a method of predicting leaf scorch. The lag model includes two rate parameters that describe 1) the process of cells accumulating non-lethal damage, and 2) damage becoming lethal to the cell. To parameterize mo...AuthorsKate J.

Formally Refereed
1. Human activities have significantly altered terrestrial ecosystems, leading to biodiversity loss and habitat fragmentation. Traditional methods for measuring human impacts often lack the precision required for localized assessments, fail to capture temporal dynamics or are scale-limited. Human mobility data (HMD) from GPS-enabled smartphone applications offers a valuable approach to understanding human movement patterns, overcoming many of these limitations. 2. We present case studies demonstrating the use of HMD in assessing human activity within ecologically sensitive habitats (e.g. winte...AuthorsHeather N. Abernathy, Mark A. Ditmer, Seth B.

Here, we examine changes in plant community structure over more than 30 years at two sites in arctic Alaska, USA, Imnavait Creek and Toolik Lake, to understand long-term trends in tundra response to changing climate. Vegetation cover was sampled every 4–7 years on permanent 1 m2 plots spanning a 1 km2 grid using a point-frame. The vascular plant canopies progressively closed at both locations.
