- Motivation: SNAPSHOT USA is an annual, multi-contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of species interactions on daily activity patterns.Main Types of Variables Contained: SNAPSHOT USA 2024 contains 377,427 records of camera trap image sequence data and 3127...AuthorsBrigit Rooney, Roland Kays, Michael V.

- Forest management planning requires the evaluation of tradeoffs in proposed management actions to meet multiple objectives, including providing the habitat required to sustain wildlife populations. However, various species-specific life history strategies and ecological uncertainties complicate our understanding of the responses of wildlife to disturbances, such as wildfires and forest management. We believe that adaptive management processes, applied through the close collaboration of researchers and managers (e.g., coproduction), will be valuable in this effort. Although adaptive...AuthorsAdam Duarte, James T. PetersonKeywordsSourceIn: Wright, Vita; Keville, Megan, tech eds.

- In this synthesis, I review biological and ecological characteristics of amphibians that are relevant to fuel-reduction treatments in upland forests, summarize the state of empirical knowledge regarding amphibian population responses to forest thinning and fire in the Pacific Northwest, and provide management considerations that balance fuel-reduction objectives with amphibian habitat needs. The scope of this review includes forested ecosystems in Oregon and Washington, with an emphasis on the west side of the Cascade Range crest where many at-risk terrestrial amphibians occur.This chapter...AuthorsDonald J.

- Wood Turtle (Glyptemys insculpta) populations are declining in many portions of the species’ native range due to multiple factors that might influence functional connectivity and population genetic structure. We used 13 microsatellite markers to examine patterns of genetic structure in the Wood Turtle across its native range in Eastern and Midwestern North America. For n = 45 collections with 15 or more individuals (total N = 1,258), multiple clustering approaches revealed two major genetic groups corresponding to the midwestern and eastern collections. Interestingly, a sample from lower...AuthorsAndrew R. Whiteley, Dana Weigel-Sheedy, Thomas S.B. Akre, Donald J. Brown, Deahn Donner, Charlie Eichelberger, Lori Erb, Katharine D.

- Spanish juniper, Juniperus thurifera L, forests are typically managed as uneven-aged forests in the Iberian range, which requires information about site index (SI) classes and diameter at breast height (dbh) distributions. The objective of this study is to evaluate and compare the performance of remote sensing models using multitemporal airborne laser scanning (ALS) data, Landsat metrics of state and change along with topographic, geographic and climatic predictors for the prediction of SI classes and diameter distributions. The best model for SI classes was a logistic model that showed an...AuthorsFrancisco Mauro, J Bernardo González-Mesquida, Manuel Gomez-Roux, Darío Domingo-Ruiz, Cristina Gómez, Lorena Caiza-Morales, Francisco Rodríguez-Puerta, Beatriz Águeda, Bryce Frank, Steven Filippelli, Andrew T.

- Background: The reintroduction of fire, with the goal of reducing fuels and restoring forest resilience, is a critical management practice in dry conifer forests of the western United States. In dry forest landscapes, invasion by non-native annual grasses could complicate restoration goals if fire exacerbates invasion and associated impacts, particularly in areas with low tree cover and in adjacent open areas. Although annual grasses are becoming increasingly pervasive across the West, little is known about how species differ in their response to burning, especially in historically...AuthorsClaire Tortorelli, Alison Dean, Meg A.

- Restoration of dry forest landscapes of the Pacific Northwest often involves the removal of some closed-canopy forest that has expanded due to fire exclusion, but this can conflict with species conservation when species require closed-canopy forest as part of their habitat. Fire refugia—areas within fire perimeters that burn less severely or frequently—might provide a solution to this conflict. We used a species-specific approach to understanding fire refugia for northern spotted owls to model the post-fire persistence of nesting and roosting (NR) forest in the frequent fire landscapes of...AuthorsJeremy T.

- As wildfires in the western US grow in both size and intensity, forest policymakers and managers seek effective ways to mitigate and adapt to increasing wildfire risk. In some regions, such as the western Pacific Northwest, where wildfires historically burned infrequently, climate change and housing development appear to be altering wildfire regimes while bringing greater numbers of people living in greater proximity to potentially more fire-prone forests. Developing effective strategies for family forest owners to adapt to the wildfire regimes of the future will depend on designing...AuthorsMahmood Muttaqee, Alexandra Paige Fischer, Aaron Groth, Jeffrey D.

- Keystone trophic interactions have disproportionate impacts on the structure and function of ecosystems by regulating the flow of nutrients through food webs. However, human disturbances alter animal habitat use and foraging behavior, with uncertain consequences for trophic interactions and the ecosystem functions they support. We simulated human activities to manipulate a keystone process—animals transporting salmon-derived nutrients from aquatic to terrestrial ecosystems—and documented the effects on animal behaviors and associated ecosystem functions. We used acoustic playbacks to alter...AuthorsPhilip Manlick, Ariel Demarest, Max Maddox, Alexa ValladolidKeywordsSourceCurrent BiologyYear2026
- Background: Wildfire can dramatically influence terrestrial landscapes, but effects on biodiversity can be hidden beneath the water’s surface. Following the 2020 Labor Day wildfires in Oregon’s western Cascade Mountain Range, we sampled 25 Oregon streams and 6 Washington streams representing a gradient of fire severity and pre-fire forest stand age to determine the effects of megafires on watershed biodiversity. In each watershed we used environmental DNA (eDNA) metabarcoding and traditional field surveys (Surber or electrofishing) to assess biodiversity.Results: Our results suggest...AuthorsLaura Hauck, Brooke Penaluna, Ashley A.
