Estimating recruitment of Largemouth Bass to exceptional weights using angler-reported catches Estimating recruitment of Largemouth Bass to exceptional weights using angler-reported catches
ABSTRACTObjective Although most facets of Largemouth Bass Micropterus nigricans ecology have been researched, the upper tiers of weight distributions (i.e., ≥3.6 kg; herein, “lunkers”) have received little attention due to the challenges of collecting sufficient sample sizes. Our aim was to estimate Largemouth Bass recruitment to higher weights after reaching 3.6 kg and to identify...

Near real-time indicators of burn severity in the western U.S. from active fire tracking Near real-time indicators of burn severity in the western U.S. from active fire tracking
Background Timely information on wildfire burn severity is critical to assess and mitigate potential post-fire impacts on soils, vegetation, and hillslope stability. Tracking individual fire spread and intensity using satellite active fire data provides a pathway to near real-time (NRT) information. Here, we generated a large database (n = 2177) of wildfire events in the western United...

Host responses and viral traits interact to shape the impacts of climate warming on highly pathogenic avian influenza in migratory waterfowl Host responses and viral traits interact to shape the impacts of climate warming on highly pathogenic avian influenza in migratory waterfowl
Emerging infectious diseases pose threats to wildlife populations, as exemplified by recent outbreaks of avian influenza viruses in wild birds. Climate change can affect infection dynamics in wildlife through direct effects on pathogens (e.g., environmental decay rates) and changes to host ecology, including shifting migration patterns. Here, we adapt an existing mechanistic model that...

Ambient field seismology in critical zone hydrological sciences Ambient field seismology in critical zone hydrological sciences
Passive ambient noise monitoring is an emerging tool in environmental seismology, leveraging the ambient seismic field to assess temporal variations in shallow subsurface properties. This review focuses on the potential and challenges of using scattered coda waves from noise correlation functions to monitor critical zone dynamics. The sensitivity of seismic velocities to various...

RioM-1: A new calcite reference material for U-Pb LA-ICP-MS geochronology RioM-1: A new calcite reference material for U-Pb LA-ICP-MS geochronology
Determining absolute ages of carbonate diagenesis, faulting, fossil formation, speleothem growth, carbonate-hosted hydrocarbon deposits, vein mineralisation and hydrothermal alteration has become increasingly accessible through LA-ICP-MS U-Pb dating of calcite, complementing traditional isotope dilution methods still applicable to certain materials (e.g., speleothems via micro-drilling)...

Synthesis of observed field salinity ranges for oyster and seagrass species in the U.S. Synthesis of observed field salinity ranges for oyster and seagrass species in the U.S.
Oyster and seagrass are important sessile, habitat-forming species that may be impacted by changes in salinity regimes from anthropogenic or climatic drivers. While salinity tolerance literature is focused on controlled experiments, observed field salinity ranges of species are more disparate. The salinity ranges in which organisms are observed in the field may not align exactly with...

Diel and spatial variability in cyanobacterial composition, gene abundance, and toxin concentration: A pilot study Diel and spatial variability in cyanobacterial composition, gene abundance, and toxin concentration: A pilot study
We designed a pilot field study to assess relations between sunlight, cyanobacteria, and cyanotoxins. In 2021, we collected day (07:00 h, 10:00 h, 13:00 h, 16:00 h) and night samples (19:00 h, 22:00 h, 01:00 h, 04:00 h) at two locations in Kabetogama Lake, MN, USA. One sample set was collected from the lakeward end of a boat dock and the other on the nearby shoreline. Cyanobacterial...

Modeling diverse environmental responses of reservoirs to floating photovoltaic systems Modeling diverse environmental responses of reservoirs to floating photovoltaic systems
Floating photovoltaic (FPV) systems are emerging as a promising strategy for large-scale clean energy production worldwide. However, by altering key physical drivers such as solar radiation and wind mixing, FPV installations may have also unintended consequences for lakes and reservoirs. Given the wide diversity of freshwater systems globally, understanding the consistency in direction...

Submarine groundwater discharge creates cold‐water refugia that can mitigate exposure of heat stress in nearshore corals Submarine groundwater discharge creates cold‐water refugia that can mitigate exposure of heat stress in nearshore corals
Coral reef mortality around the world is accelerating due to human activities and rising sea temperatures that cause bleaching, which is expected to become more frequent. Our ability to predict which corals will be most resilient, however, remains limited due to insufficient information characterizing nearshore temperature and habitat conditions. In this study, we examine how submarine...

Assessing flood water infiltration and storage in a restored floodplain Assessing flood water infiltration and storage in a restored floodplain
In urban areas, floodplain restoration is gaining prominence as a strategy for restoring the natural functions of floodplain ecosystems and reducing flood risk. This has spurred research into potential interactions between floodwaters, the hyporheic zone, and the floodplain aquifer. An urban restored stream in Wisconsin, USA, was used as a case study to examine four methods to estimate...

Case study of deep learning image segmentation for the purposes of rapid 2D petrographic analysis in volcanic rocks Case study of deep learning image segmentation for the purposes of rapid 2D petrographic analysis in volcanic rocks
Automation using deep learning methods is a useful alternative to manual methods of petrographic segmentation, but often requires user familiarity with coding and/or algorithms. We examine the DragonflyTM program's deep learning tools for application by users with a variety of skill levels as a method for petrographic image segmentation. An image processing methodology, bimodal image...

Pre-Acadian tectonics of the eastern Orange-Milford Belt, south-central Connecticut Pre-Acadian tectonics of the eastern Orange-Milford Belt, south-central Connecticut
This excursion presents a reinterpretation of mapping and new analytical data from the eastern Orange-Milford belt (OMB) in south-central Connecticut. The OMB is a fault-bound terrane of argillites and mafic rocks of anomalously low metamorphic grade—and of poorly constrained ages and tectonic affinity—wedged between kyanite/sillimanite-grade peri- Laurentian rocks to the west and...
