Theory suggests that songbirds should depart on migration shortly after sunset to maximize their potential for nightly flight duration or to time departure with the emergence of celestial cues needed for orientation and navigation. Although captive studies have found that songbirds depart during a narrow window of time after sunset, observational studies have found that wild birds depart later and more asynchronously relative to sunset than predicted. Methods: We used coded radio tags...AuthorsNathan W. Cooper, Bryant C. Dossman, Lucas E. Berrigan, J. Morgan Brown, Alicia R. Brunner, Helen E. Chmura, Dominic A.

- This National Report on Sustainable Forests (NRSF) presents a comprehensive assessment of sustainability conditions and trends in forests of the United States. It is produced in response to the United States' political and institutional commitment to measure, monitor, and report on forest sustainability at national and subnational levels using the Montréal Process Criteria and Indicators (C&I) for the Conservation and Sustainable Management of Temperate and Boreal Forests (Robertson et al. 2011).AuthorsKathleen McGinley, Lara T.

- Social practice theory offers a multidisciplinary perspective on the relationship between infrastructure and wellbeing. One prominent model in practice theory frames systems of provision as the rules, resources, and structures that enable the organization of social practices, encompassing both material and immaterial aspects of infrastructures. A second well-known model frames social practices in terms of their constituent elements: meanings, materials, and competences. Reconciling these two models, we argue that household capacity to respond to shifting systems of provision to maintain...AuthorsSonya Ahamed, Chelsea Schelly, Kristin Floress, William Lytle, Holly Caggiano, Cara L.

- Forests are widely recognized as critical to combating climate change due to their ability to sequester and store carbon in the form of biomass. In recent years, the combined use of data from ground-based forest inventories and remotely sensed data from light detection and ranging (lidar) has proven useful for large-scale assessment of forest biomass, but airborne lidar is expensive and data acquisition is infeasible for many countries. By contrast, the spaceborne Global Ecosystem Dynamics Investigation (GEDI) lidar instrument has collected freely available data for most of the world’s...AuthorsEric Bullock, Sean P.

- Balsam woolly adelgid (Hemiptera: Adelges picea Ratzeburg; BWA) is a nonnative, invasive insect that has infested fir trees in the US for over a century, yet robust methods for mapping BWA have remained elusive. We compare three approaches to mapping BWA in the subalpine fir forests of northern Utah, the forefront of BWA spread in the western US: (1) using moderate-resolution, multispectral satellite imagery; (2) using terrain and climate data; and (3) using a combination of imagery, terrain, and climate data. While the spectral data successfully detected forest degradation, they failed to...AuthorsMichael J. Campbell, Justin P. Williams, Erin BerrymanKeywordsSourceForests. 14: 1357.Year2023
- We developed and applied a spatial optimization algorithm to prioritize forest and fuel management treatments within a proposed linear fuel break network on a 0.5 million ha Western US national forest. The large fuel break network, combined with the logistics of conducting forest and fuel management, requires that treatments be partitioned into a sequence of discrete projects, individually implemented over the next 10-20 years. The original plan for the network did not consider how linear segments would be packaged into projects and how projects would be prioritized for treatments over...AuthorsPedro Belavenutti, Alan Ager, Michelle A.

- 1. Recent hot droughts in California resulted in ponderosa pine (Pinus ponderosa) mortality attributed to drought and western pine beetle (WPB, Dendroctonus brevicomis). While drought alone can cause tree death, direct warming effects on WPB are a contributing factor. Research on WPB generation timing (voltinism), however, is lacking.2. We monitored WPB tree attacks and adult emergence timing at two California sites and developed a degree-day model from field-observed data. Historical, contemporary, and future temperatures for several California sites were used with the model to examine...AuthorsBarbara J. Bentz, Daniel R. Cluck, Beverly M. Bulaon, Sheri L.

- 1. Fragmentation of habitat, for example by intensive agricultural practices, can be detrimental to local biodiversity. However, it often remains unclear whether such biodiversity declines are caused by loss of habitat area or increased fragmentation, and how habitat quality factors into it. In our study system, vegetated vineyards are typically small, and isolated from one another, potentially limiting the distribution and dispersal of organisms.2. In a full-factorial experiment of a priori selected vegetated vineyard patches of differing size and fragmentation, we aimed to disentangle...AuthorsLaura Bosco, Valentin Moser, Mirkka M.

- Numerous studies have shown that climate change has altered avian timing of breeding. However, little is known about climate-driven changes in offspring production. We collected long-term breeding data on 201 populations of 104 bird species (N = 745,962 clutches) from all continents, between 1970 and 2019, to assess temporal changes in annual offspring production by female breeders in relation to changes in local temperatures and species’ life history traits. Overall, offspring production declined over time, but responses of different populations to rising temperatures were diverse. Our...AuthorsAndrew G.

- The relationship between traffic and forest road erosion has been studied for decades, and the answer to the question “what happens when traffic is present on unpaved forest roads?” is simple: erosion increases. However, the answer to the question “why does it increase?” is complex and requires us to consider forest road erosion through an integrated lens. Fully understanding how traffic affects forest road erosion will allow us to control forest road erosion effectively. In this synthesis, we look at forest road erosion literature and focus the discussion on the interactions between...AuthorsAmanda D. Alvis, Charlie H.
