Pollinator conservation and climate science at the U.S. Geological Survey Pollinator conservation and climate science at the U.S. Geological Survey
Introduction Ecosystems—whether agricultural, urban, or natural—depend on pollinators, great and small. Pollinators in the form of bees, birds, butterflies, bats, and even moths provide vital, but often invisible services, from contributing to biodiverse terrestrial wildlife and plant communities to supporting healthy watersheds. Pollinator declines worldwide have been noted as land-use...

Dynamic spatiotemporal modeling of a habitat-defining plant species to support wildlife management at regional scales Dynamic spatiotemporal modeling of a habitat-defining plant species to support wildlife management at regional scales
Sagebrush (Artemisia spp.) ecosystems provide critical habitat for the Greater sage-grouse (Centrocercus urophasianus), a species of conservation concern. Thus, future loss of sagebrush habitat because of land use change and global climate change is of concern. Here, we use a dynamic additive spatiotemporal model to estimate the effects of climate on sagebrush cover dynamics at 32 sage...

Increased aridity is associated with stronger tradeoffs in ponderosa pine vital functions Increased aridity is associated with stronger tradeoffs in ponderosa pine vital functions
Trees must allocate resources to core functions like growth, defense, and reproduction. These allocation patterns have profound effects on forest health, yet little is known about how core functions trade off over time, and even less is known about how a changing climate will impact tradeoffs. We conducted a 21-year survey of growth, defense, and reproduction in 80 ponderosa pine...

Masting is uncommon in trees that depend on mutualist dispersers in the context of global climate and fertility gradients Masting is uncommon in trees that depend on mutualist dispersers in the context of global climate and fertility gradients
The benefits of masting (volatile, quasi-synchronous seed production at lagged intervals) include satiation of seed predators, but these benefits come with a cost to mutualist pollen and seed dispersers. If the evolution of masting represents a balance between these benefits and costs, we expect mast avoidance in species that are heavily reliant on mutualist dispersers. These effects...

Temporal patterns of structural sagebrush connectivity from 1985 to 2020 Temporal patterns of structural sagebrush connectivity from 1985 to 2020
The sagebrush biome within the western United States has been reshaped by disturbances, management, and changing environmental conditions. As a result, sagebrush cover and configuration have varied over space and time, influencing processes and species that rely on contiguous, connected sagebrush. Previous studies have documented changes in sagebrush cover, but we know little about how...

Modeling, mapping, and measuring the risk of freshwater invasive species across Alaska Modeling, mapping, and measuring the risk of freshwater invasive species across Alaska
Freshwater ecosystems of the Alaskan Arctic and Subarctic provide resources that are culturally, ecologically, and economically invaluable. Presently, these regions are relatively free of the impacts from invasive species compared to southern latitudes. To date, there have been relatively few verified introductions of aquatic invasive species (AIS) to freshwater ecosystems in Alaska. The...

Living with wildfire in Emigration Canyon, Utah: 2022 data report Living with wildfire in Emigration Canyon, Utah: 2022 data report
Located in North Central Utah, Emigration Canyon is a prominent and historic canyon that runs northeast from Salt Lake City into the higher elevations of the Wasatch Mountains. The Wasatch Range is characterized by steep, rocky slopes and 26-44 millimeters of annual rainfall, both of which contribute to a high threat of wildfire. The area’s landscape is diverse with oak woodland at the...

Invasion-mediated mutualism disruption is evident across heterogeneous environmental conditions and varying invasion intensities Invasion-mediated mutualism disruption is evident across heterogeneous environmental conditions and varying invasion intensities
The impact of a biological invasion on native communities is expected to be uneven across invaded landscapes due to differences in local abiotic conditions, invader abundance, and traits and composition of the native community. One way to improve predictive ability about the impact of an invasive species given variable conditions is to exploit known mechanisms driving invasive species'...

A retrospective assessment of fuel break effectiveness for containing rangeland wildfires in the sagebrush biome A retrospective assessment of fuel break effectiveness for containing rangeland wildfires in the sagebrush biome
Escalated wildfire activity within the western U.S. has widespread societal impacts and long-term consequences for the imperiled sagebrush (Artemisia spp.) biome. Shifts from historical fire regimes and the interplay between frequent disturbance and invasive annual grasses may initiate permanent state transitions as wildfire frequency outpaces sagebrush communities’ innate capacity to...

Plague mitigation for prairie dog and black-footed ferret conservation: Degree and duration of flea control with 0.005% fipronil grain bait Plague mitigation for prairie dog and black-footed ferret conservation: Degree and duration of flea control with 0.005% fipronil grain bait
Sylvatic plague, a primarily flea-borne zoonosis, is a significant threat to prairie dogs (Cynomys spp., PDs) and their specialized predators, endangered black-footed ferrets (Mustela nigripes, BFFs). Host-fed fipronil baits have proven effective in controlling fleas on PDs for the purposes of plague mitigation and BFF conservation. Currently, annual treatments are the norm. We tested...

The Science Application for Risk Reduction (SAFRR) Scenario Retrospective 2006–21 The Science Application for Risk Reduction (SAFRR) Scenario Retrospective 2006–21
The U.S. Geological Survey Science Application for Risk Reduction (SAFRR) Project has created four major hazard scenarios—ShakeOut, ARkStorm, Tsunami Scenario, and HayWired—with multidisciplinary teams of scientists, academics, and practitioners. By presenting a clear and highly detailed narrative of potential damage from earthquakes, tsunamis, and winter storms, the scenarios are...
