Relatedness of white-tailed deer from culling efforts within chronic wasting disease management zones in Minnesota Relatedness of white-tailed deer from culling efforts within chronic wasting disease management zones in Minnesota
In white-tailed deer (Odocoileus virginianus), closely related females form social groups, avoiding other social groups. Consequently, females infected with chronic wasting disease (CWD) are more likely to infect social group members. Culling has been used to reduce CWD transmission in high-risk areas; however, its effectiveness in removing related individuals has not been assessed. We...

Microbial ecology of permafrost soils: Populations, processes, and perspectives Microbial ecology of permafrost soils: Populations, processes, and perspectives
Permafrost microbial research has flourished in the past decades, due in part to improvements in sampling and molecular techniques, but also the increased focus on the permafrost greenhouse gas feedback to climate change and other ecological processes in high latitude and alpine permafrost soils. Permafrost microorganisms are adapted to these extreme environments and remain active at low

Burbot population dynamics in northern Lake Michigan, 2001–2023, and predation on newly stocked lake trout by burbot Burbot population dynamics in northern Lake Michigan, 2001–2023, and predation on newly stocked lake trout by burbot
Although the worldwide status of burbot (Lota lota) across its Holarctic distribution has recently been assessed, adverse effects of dreissenid mussels on burbot abundance in waters invaded by mussels have not been investigated. We analyzed data from an annual spring gillnet survey to characterize burbot population dynamics in northern Lake Michigan during 2001–2023. Adult burbot...

Enhancing One Health outcomes using decision science and negotiation Enhancing One Health outcomes using decision science and negotiation
One Health initiatives have advanced zoonotic disease management by recognizing the interconnectedness of three sectors of governance (human, ecosystem, and animal) and by identifying options that can improve full-system health. Although One Health has had many successes, its full realization may be inhibited by a lack of strategies to overcome simultaneous impediments in decision making...

Chemostratigraphy of the Cretaceous Hue Shale in Arctic Alaska: Exploring paleoceanographic controls on trace element enrichment, organic matter accumulation, and source-rock evolution Chemostratigraphy of the Cretaceous Hue Shale in Arctic Alaska: Exploring paleoceanographic controls on trace element enrichment, organic matter accumulation, and source-rock evolution
We document chemostratigraphy in an outcrop of late Albian to early Campanian (∼103–82 Ma) marine source rocks to better understand paleoenvironmental controls on trace element (TE) enrichment and organic matter accumulation in the distal Colville foreland basin of Arctic Alaska and how those drivers are linked to arc volcanism and successions of Cretaceous oceanographic and climatic

History of terrestrial ecosystem development in southern Alexander Archipelago, Alaska since the onset of deglaciation History of terrestrial ecosystem development in southern Alexander Archipelago, Alaska since the onset of deglaciation
This chapter focuses on reconstructing the history of vegetation development in southern Alexander Archipelago (AA) of southeast Alaska during and after deglaciation up to the present day. It also summarizes key findings from recent paleoceanographic research in the Gulf of Alaska to provide a detailed, well-dated record of late Quaternary climate changes for the region. Understanding...

An enigmatic wild passerine mortality event in the eastern United States An enigmatic wild passerine mortality event in the eastern United States
The ability to rapidly respond to wildlife health events is essential. However, such events are often unpredictable, especially with anthropogenic disturbances and climate-related environmental changes driving unforeseen threats. Many events also are short-lived and go undocumented, making it difficult to draw on lessons learned from past investigations. We report on the response to a...

Understanding and predicting infection dynamics for an endangered amphibian using long-term surveys of wild and translocated frogs Understanding and predicting infection dynamics for an endangered amphibian using long-term surveys of wild and translocated frogs
Amphibians are a prominent component of Earth's sixth mass extinction and the fungal pathogen Batrachochytrium dendrobatidis (Bd) is a primary driver of declines. Although Bd dynamics are well studied, the environmental drivers, exacerbating risk factors, and value of conservation interventions like translocations remain challenging to predict. Here, we present results from two decades...

Integrated Hydro-terrestrial Modeling 2.0: Progress and path forward on building a national capability Integrated Hydro-terrestrial Modeling 2.0: Progress and path forward on building a national capability
Growing societal pressures on U.S. water resources and the challenges inherent in understanding how future water risks may evolve are driving major investments to improve our knowledge of the integrated water cycle. This improved understanding as captured in innovations in our data, knowledge, and modeling capabilities, needs to be accelerated through better integration and coordination...

DNA metabarcoding of biocrust lichen-forming fungi detects responses to disturbance and invasion DNA metabarcoding of biocrust lichen-forming fungi detects responses to disturbance and invasion
Biocrusts dominated by bryophytes and lichens perform important functions in dryland ecosystems but monitoring these communities can be cost prohibitive over broad scales. We explored DNA metabarcoding as a potential tool for monitoring biocrust lichen communities at a site in Washington (U.S.A.) that had already been surveyed for lichen diversity and community composition. We developed...

Sampling mass mortality events to enable diagnoses: A protocol using freshwater mussels Sampling mass mortality events to enable diagnoses: A protocol using freshwater mussels
Many taxa around the globe are threatened by often unexplained mass mortality events (MMEs), which can decimate populations and compromise key ecosystem functions. One example of a highly threatened taxon facing frequent MMEs is freshwater mussels (Unionida).There has been a recent increase in interest in understanding the causes of freshwater mussel MMEs, but standardised methodologies...
