Semi-automated methods to develop a unified geographic information system dataset
Jason L. Shapiro, David I. Donato
2024, Techniques and Methods 11-C10
Geospatial data describing the topography, natural features, human-built features, and land uses of a particular area or region can come from independent data providers and, therefore, vary in format, data encoding, and geographic coverage. Because of the complexity of the processes and procedures required for unifying these heterogeneous data into...

Patil Tawidian, Mia K. Torchetti, Mary Lea Killian, Kristina Lantz, Krista E. Dilione, Jourdan M. Ringenberg, Sarah N. Bevins, Juliana Lenoch, Hon S. Ip
2024, Viruses (16)
The introduction of HPAI H5N1 clade 2.3.4.4b viruses to North America in late 2021 resulted in avian influenza outbreaks in poultry, mortality events in many wild bird species, and spillover into many mammalian species. Reassortment events with North American low pathogenic virus were identified as early as February 2022 and...

Peter C. Esselman, Shadi Moradi, Joseph K. Geisz, Christopher Roussi
2024, Methods in Ecology and Evolution
1. Benthic fishes are a common target of scientific monitoring but are difficult to quantify because of their close association to bottom habitats that are hard to access. Advances in image-acquisition technologies, machine vision, and deep learning have made capturing and quantifying fishes with cameras increasingly feasible. We present a...

Zebra mussels (Dreissena polymorpha) are invasive species that alter ecosystems and food webs with the potential to affect aquatic mercury cycling and bioaccumulation in fishes, although the effect of zebra mussels on fish tissue mercury has not been tested in inland lakes. We assessed differences in fish tissue mercury concentrations...
Surveying waterfowl broods in wetlands using aerial drones
Desmond Alexander Mackell, Michael L. Casazza, Cory T. Overton, Kevin Buffington, Chase M. Freeman, Josh T. Ackerman, Karen M. Thorne
2024, San Francisco Estuary and Watershed Science (22)
Effective waterfowl management relies on the collection of relevant demographic data to inform land management decisions; however, some types of data are difficult to obtain. For waterfowl, brood surveys are difficult to conduct because wetland habitats often obscure ducklings from being visually assessed. Here, we used Unoccupied Aerial Systems (UAS)...

Robert L. Jenkins III, Christopher G. Smith, Davina Passeri, Alisha M. Ellis
2024, Journal of Marine Science and Engineering (12)
Numerical simulation of sediment transport and subsequent morphological evolution rely on accurate parameterizations of sediment characteristics. However, these data are often not available or are spatially and/or temporally limited. This study approaches the problem of limited sediment grain-size data with a series of simulations assessing model sensitivity to sediment parameters...

2024, Chemosphere (368)
Quaternary ammonium compounds (QAC) are high production chemicals used in many commercial and household disinfection products. During the SARS-CoV-2 (COVID-19) pandemic, QACs were included on lists of COVID-19 disinfectants. Increased QAC use could lead to higher levels of QACs in wastewater treatment plant (WWTP) effluents, which could subsequently be released...

Wei Zhi, Hubert Baniecki, Jiangtao Liu, Elizabeth W. Boyer, Chaopeng Shen, Gary W. Shenk, Xiaofeng Liu, Li Li
2024, PNAS (121)
The loss of phosphorous (P) from the land to aquatic systems has polluted waters and threatened food production worldwide. Systematic trend analysis of P, a nonrenewable resource, has been challenging, primarily due to sparse and inconsistent historical data. Here, we leveraged intensive hydrometeorological data and the recent renaissance of deep...

Thierry M. Work, Jeff Miller, Thomas Kelley, Aine C. Hawthorn, Tina Weatherby, Caroline Rogers
2024, Coral Reefs
Stony coral tissue loss disease (SCTLD) was first documented in Florida in 2014 and has since spread through the Caribbean causing unprecedented mortality in more than 20 species of corals. The cause of SCTLD is unknown, but bacteria are suspected based on regression of gross lesions in some corals treated...

Jonathan Caine, Omero F. Orlandini, Frederick W. Vollmer, Heather A. Lowers
2024, Journal of Geophysical Research: Solid Earth (129)
Rare bedrock exposures of the eastern Denali fault zone in southwestern Yukon allow for the measurement, sampling, and analyses of brittle regime fault slip data and deformation mechanisms to explore relations to far field, oblique plate motions. Host rock lithologies and associated slip surfaces show episodic damage zone‐related deformation and...

2024, Frontiers in Cellular and Infection Microbiology (14)
Introduction: The long-distance, seasonal migrations of birds make them an effective ecological bridge for the movement of ticks. The introduction of exotic tick species to new geographical regions can cause the emergence of novel tick-borne pathogens. This study examined the prevalence of exotic tick species parasitizing migratory songbirds at stopover sites...
Layered intrusions in the Precambrian: Observations and perspectives
William D. Smith, Michael Jenkins, Claudia T. Augustin, Ville J. Virtanen, Zoja Vukmanovic, Brian O'Driscoll
2024, Precambrian Research (415)
Layered intrusions are plutonic bodies of cumulates that form by the crystallization of mantle-derived melts. These intrusions are characterized by igneous layering distinguishable by shifts in mineralogy, texture, or composition. Layered intrusions have been fundamental to our understanding of igneous petrology; however, it is their status as important repositories of...
Hydroacoustic observations reveal drivers of mixing and salinization of a karst subterranean estuary during intense precipitation
Neil K. Ganju, John Pohlman, Steven E. Suttles, David Brankovits
2024, Geophysical Research Letters (51)
Karst subterranean estuaries within globally ubiquitous carbonate aquifers are coastal groundwater ecosystems that provide an essential water resource for human populations. To understand the drivers of salinization within a coastal aquifer in the Yucatan Peninsula (Mexico), we employed hydroacoustics in flooded caves to observe how oceanic and atmospheric events facilitate...
