Connectivity patterns between floodplain lakes and neighboring streams in the historical floodplain of the Lower Mississippi River Connectivity patterns between floodplain lakes and neighboring streams in the historical floodplain of the Lower Mississippi River
Hydrologic connectivity, the network of water pathways linking aquatic habitats, is vital for the exchange of organisms and abiotic materials between rivers and adjacent waterbodies. This study quantified hydrologic connectivity for 1,283 lakes in the Lower Mississippi River floodplain using satellite imagery, streamgauge data, and geospatial information. We aimed to assess connection...

Peak streamflow trends in South Dakota and their relation to changes in climate, water years 1921–2020 Peak streamflow trends in South Dakota and their relation to changes in climate, water years 1921–2020
Peak-flow (flood) frequency analysis is essential to water-resources management applications, including the design of critical infrastructure such as bridges and culverts, and floodplain mapping. Federal guidelines for performing peak-flow flood frequency analyses are presented in a U.S. Geological Survey Techniques and Methods Report known as Bulletin 17C. A basic assumption within...

Deep syntectonic burial of the Anthracite belt, Eastern Pennsylvania Deep syntectonic burial of the Anthracite belt, Eastern Pennsylvania
Fluid inclusion microthermometry and Raman spectroscopy of fluid inclusions in quartz veins from the Pennsylvanian rocks of the Anthracite belt, eastern Pennsylvania support a deep burial model of coalification in favor of focused orogenic hot fluid flow. High-temperature (250 to 255 °C) trapping of CH4 ± CO2 saturated aqueous fluids and CH4 ± CO2 inclusions indicate fluid trapping at...

Biological feasibility of introducing bighorn sheep to the Jicarilla Apache Nation Biological feasibility of introducing bighorn sheep to the Jicarilla Apache Nation
The biological feasibility of introducing Rocky Mountain bighorn sheep (Ovis canadensis canadensis) to the Dulce area of the Jicarilla Apache Nation (JAN) depends on availability and condition of potential habitat and the potential for disease risk, as pneumonia is the largest current threat to wild sheep populations. We modeled quality and quantity of potential bighorn sheep habitat...

Riparian methylmercury production increases riverine mercury flux and food web concentrations Riparian methylmercury production increases riverine mercury flux and food web concentrations
The production and uptake of toxic methylmercury (MeHg) impacts aquatic ecosystems globally. Rivers can be dynamic and difficult systems to study for MeHg production and bioaccumulation, hence identifying sources of MeHg to these systems is both challenging and important for resource management within rivers and main-stem reservoirs. Riparian zones, which are known biogeochemical...

Near-term ecological forecasting for climate change action Near-term ecological forecasting for climate change action
A substantial increase in predictive capacity is needed to anticipate and mitigate the widespread change in ecosystems and their services in the face of climate and biodiversity crises. In this era of accelerating change, we cannot rely on historical patterns or focus primarily on long-term projections that extend decades into the future. In this Perspective, we discuss the potential of...

Effects of release strategy, source population, and age on reintroduced scaled quail reproduction Effects of release strategy, source population, and age on reintroduced scaled quail reproduction
Translocation is one strategy to reestablish populations of scaled quail (Callipepla squamata). Initial reproductive success post-translocation is important for establishing short-lived species such as quail, but factors influencing reproductive success are poorly understood. We evaluated the effect of source population and variation in delayed release strategy (1−9 weeks) on nest...

Upper Mississippi River System hydrogeomorphic change conceptual model and hierarchical classification Upper Mississippi River System hydrogeomorphic change conceptual model and hierarchical classification
Understanding the geomorphic processes and causes for long-term hydrogeomorphic changes along the Upper Mississippi River System (UMRS) is necessary for scientific studies ranging from habitat needs assessments, sediment transport, and nutrient processing, and making sound management decisions and prioritizing ecological restoration activities. From 2018 through 2020 the U.S. Geological...

Intense alteration on early Mars revealed by high-aluminum rocks at Jezero Crater Intense alteration on early Mars revealed by high-aluminum rocks at Jezero Crater
The NASA Perseverance rover discovered light-toned float rocks scattered across the surface of Jezero crater that are particularly rich in alumina ( ~ 35 wt% Al2O3) and depleted in other major elements (except silica). These unique float rocks have heterogeneous mineralogy ranging from kaolinite/halloysite-bearing in hydrated samples, to spinel-bearing in dehydrated samples also...

Depths in a day - A new era of rapid-response Raman-based barometry using fluid inclusions Depths in a day - A new era of rapid-response Raman-based barometry using fluid inclusions
Rapid-response petrological monitoring is a major advance for volcano observatories, allowing them to build and validate models of plumbing systems that supply eruptions in near-real-time. The depth of magma storage has recently been identified as high-priority information for volcanic observatories, yet this information is not currently obtainable via petrological monitoring methods on...

Indigenous knowledge in climate adaptation planning: Reflections from initial efforts Indigenous knowledge in climate adaptation planning: Reflections from initial efforts
There are increasing calls to incorporate indigenous knowledge (IK) into climate adaptation planning (CAP) and related projects. However, given unique attributes of IK and the positionality of tribal communities to scientific research, several considerations are important to ensure CAP efforts with IK are ethical and effective. While such topics have been thoroughly explored conceptually

Real-time pier scour monitoring and observations at three scour-critical sites in Idaho, water years 2020–22 Real-time pier scour monitoring and observations at three scour-critical sites in Idaho, water years 2020–22
To observe real-time pier scour at three scour-critical sites in Idaho, the U.S. Geological Survey, in cooperation with Idaho Transportation Department, installed and operated fixed real-time (15-minute interval) bed elevation scour sonar sensors at three bridge locations associated with U.S. Geological Survey streamflow gaging stations for water years 2020 through 2022. Daily mean and...
