Successes and opportunities for solutions-oriented conservation research: Lessons learned from avian science Successes and opportunities for solutions-oriented conservation research: Lessons learned from avian science
Conservation science struggles with an ongoing divide between research and action. Given its history of broad public engagement and multi-scale management coordination, avian conservation typifies many of the challenges, successes, and opportunities across the broader field of conservation and is rich with examples that may guide solutions-oriented conservation science. In semi...

Corundum discovered by SuperCam and the Perseverance rover at Jezero crater, Mars Corundum discovered by SuperCam and the Perseverance rover at Jezero crater, Mars
Mars is primarily composed of mafic mineral assemblages and their alteration products, but small, scattered rocks strewn across the landscape offer clues to greater petrological diversity. While traversing the Jezero crater rim, the Perseverance rover encountered several plagioclase-rich light-toned float rocks. SuperCam identified the distinctive signature of corundum (α-Al2O3) in these...

A dataset of fluvial fish richness metrics for stream reaches across the conterminous United States A dataset of fluvial fish richness metrics for stream reaches across the conterminous United States
Fluvial fishes, those primarily inhabiting rivers and streams, are facing substantial threats in their native ranges from habitat degradation which contributes to decreases in richness and abundance of many species. Because distributions of fluvial species are often not well developed across large spatial scales, the ability to understand the consequences of threats is limited. Species

Digitizer Suite: The Albuquerque Seismological Laboratory Digitizer Testing Suite Digitizer Suite: The Albuquerque Seismological Laboratory Digitizer Testing Suite
Laboratory testing of digitizers and seismometers helps ensure that prior to deployment the instrumentation can produce high quality data and is operating within specifications. In this work we detail the software package called: the Albuquerque Seismological Laboratory (ASL) Digitizer Test Suite. This Java software package provides several algorithms to verify various performance...

Validation of daily age in Grass Carp reared in tanks and outdoor ponds in the U.S. Midwest Validation of daily age in Grass Carp reared in tanks and outdoor ponds in the U.S. Midwest
Objective Accurate and precise age estimation is essential for understanding early life history, recruitment, and population dynamics in fish. However, daily otolith increment deposition has not been validated for Grass Carp Ctenopharyngodon idella in the Midwestern United States. Our objective was to validate daily increment deposition in lapilli otoliths of known-age Grass Carp that...

Recycling radiogenic osmium by crustal foundering in subduction zones: Evidence from pyroxenite xenoliths in the north Andean arc Recycling radiogenic osmium by crustal foundering in subduction zones: Evidence from pyroxenite xenoliths in the north Andean arc
Removal of mafic-ultramafic lower crust (e.g., via delamination) is fundamental to making andesitic continental crust, yet direct evidence of this process remains elusive. A unique suite of garnet clinopyroxenite and hornblendite (arclogite) xenoliths from the northern volcanic zone of the Andes, erupted to the surface in the mid-Pleistocene, have bulk-rock geochemistry and osmium (Os)...

Ground failure resulting from earthquake ground motions Ground failure resulting from earthquake ground motions
The ground failure resulting from an earthquake, at all scales, is ultimately controlled by the details of near-surface earthquake ground motions, the spatially distributed mechanical characteristics of surface materials and how the two interact. This chapter introduces the aspects of ground-motion seismology that are most relevant to the triggering of different types of ground failure...

Navigating uncertainty and competing objectives: Spring chinook salmon recovery in the upper Willamette river Navigating uncertainty and competing objectives: Spring chinook salmon recovery in the upper Willamette river
Globally, anadromous fish populations are threatened with extinction due to multiple factors, including river impoundments that block migration, widespread alteration of physical habitat, temperature, and flow regimes, commercial and recreational harvest, changes in biological communities, and long-term climate trends. In this synthesis, we describe how physical and biological factors...

Interaction between sex and contaminant type attributable to males eliminating mercury at a faster rate Interaction between sex and contaminant type attributable to males eliminating mercury at a faster rate
The observed interaction between sex and contaminant type (polychlorinated biphenyls (PCBs) or mercury (Hg)) in adult teleost fishes is most likely due to adult males having a substantially higher Hg-elimination rate than adult females. In contrast, long-term elimination of PCBs by teleost fishes has been characterized as negligible for both sexes. In addition, the variation in the...

An alternative approach to studying humpback whale song changes over time using occupancy models An alternative approach to studying humpback whale song changes over time using occupancy models
Humpback whales produce complex, structured songs that vary among individuals, populations, and through time. This study presents a novel method of studying changes in humpback whale song elements through time while accounting for detection probability.

Where will the cat cross the road? Comparing camera and GPS-based models for identifying wildlife corridors Where will the cat cross the road? Comparing camera and GPS-based models for identifying wildlife corridors
Designing effective wildlife corridors is a critical conservation challenge in fragmented landscapes. GPS-based step selection functions strongly predict dispersal corridors and connectivity, but GPS collaring can be expensive and invasive. Camera-based occupancy models are widely used for connectivity analyses but may involve trade-offs in data resolution. Despite widespread use of both

Water-withdrawal and groundwater-level fluctuations, physical and infiltration characteristics of Ohio River sediment, and isotope-based estimates of water sources relative to a riverbank filtration system in an alluvial aquifer, Louisville, Kentucky, 200 Water-withdrawal and groundwater-level fluctuations, physical and infiltration characteristics of Ohio River sediment, and isotope-based estimates of water sources relative to a riverbank filtration system in an alluvial aquifer, Louisville, Kentucky, 200
The U.S. Geological Survey and the Louisville Water Company, from 2000 to 2020, cooperatively investigated physical and hydrologic conditions in the Ohio River alluvial aquifer and adjacent riverbed sediments in the northeast part of Louisville, Kentucky, to increase knowledge of processes affecting water sources to collector wells during operation of a riverbank filtration system (RBF)...
