Snahamoy Chatterjee, Maria Mastalerz, Agnieszka Drobniak, C. Ozgen Karacan
2022, International Journal of Coal Geology (259)
Rare earth elements and yttrium (REYs) are critical elements and valuable commodities due to their limited availability and high demand in a wide range of applications and especially in high-technology products. The increased demand and geopolitical pressures motivate the search for alternative sources of REYs, and coal, coal waste, and...
Modeling spatiotemporal abundance and movement dynamics using an integrated spatial capture–recapture movement model
Nathan J. Hostetter, E.V. Regehr, R.R. Wilson, Andy Royle, Sarah J. Converse
2022, Ecology (103)
Animal movement is a fundamental ecological process affecting the survival and reproduction of individuals, the structure of populations, and the dynamics of communities. Methods to quantify animal movement and spatiotemporal abundances, however, are generally separate and therefore omit linkages between individual-level and population-level processes. We describe an integrated spatial capture–recapture...

2022, Environmental Science and Pollution Research (29) 74024-74037
An important component of assessing the hazards of anticoagulant rodenticides to non-target wildlife is observations in exposed free-ranging individuals. The objective of this study was to determine whether environmentally realistic, sublethal first-generation anticoagulant rodenticide (FGAR) exposures via prey can result in direct or indirect adverse effects to free-flying raptors. We...

Feng Cheng, Nathaniel J. Lindsey, Valeriia Sobolevskaia, Shan Dou, Barry Freifeld, Todd Wood, Stephanie R. James, Anna M. Wagner, Jonathan B. Ajo-Franklin
2022, Geophysical Research Letters (49)
Permafrost degradation is rapidly increasing in response to a warming Arctic climate, altering landscapes and damaging critical infrastructure. Solutions for monitoring permafrost thaw dynamics are essential to understand biogeochemical feedbacks as well as to issue warnings for hazardous geotechnical conditions. We investigate the feasibility of permafrost monitoring...

Advances in the study and understanding of groundwater discharge to surface water
Carlos Duque, Donald O. Rosenberry
2022, Water (14)
Groundwater discharge is vitally important for maintaining or restoring valuable ecosystems in surface water and at the underlying groundwater-surface-water ecotone. Detecting and quantifying groundwater discharge is challenging because rates of flow can be very small and difficult to measure, exchange is commonly highly heterogeneous both in space and time, and...

Savinay Nagendra, Daniel Kifer, Benjamin B. Mirus, Te Pei, Kathryn Lawson, Srikanth Banagere Manjunatha, Weixin Li, Hien Nguyen, Tong Qiu, Sarah Tran, Chaopeng Shen
2022, IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing (15) 4349-4370
Preparation and mitigation efforts for widespread landslide hazards can be aided by a large-scale, well-labeled landslide inventory with high location accuracy. Recent smallscale studies for pixel-wise labeling of potential landslide areas in remotely-sensed images using deep learning (DL) showed potential but were based on data from very small, homogeneous regions...

Climate change will continue to be an important consideration for conservation practitioners. However, uncertainty in identifying appropriate management strategies, particularly for understudied species and regions, constrains the implementation of science-based solutions and adaptation strategies. Here, we share a decision-path approach to reduce uncertainty in climate change responses of inland fishes...
