Variation in within-host replication kinetics among virus genotypes provides evidence of specialist and generalist infection strategies across three salmonid host species
David James Páez, Douglas G. McKenney, Maureen K. Purcell, Kerry A. Naish, Gael Kurath
2022, Virus Evolution (8)
Theory of the evolution of pathogen specialization suggests that a specialist pathogen gains high fitness in one host, but this comes with fitness loss in other hosts. By contrast, a generalist pathogen does not achieve high fitness in any host, but gains ecological fitness by exploiting different hosts, and...

2022, Frontiers in Earth Science (10)
Volcanic ash is a hazard to human health and activities. Accurate and timely forecasts coupled with effective communication about the dispersion and fallout of volcanic ash during explosive events are essential to reduce impacts on local communities and limit economic losses. In this study, we present the first...

High-latitude peatlands are changing rapidly in response to climate change, including permafrost thaw. Here, we reconstruct hydrological conditions since the seventeenth century using testate amoeba data from 103 high-latitude peat archives. We show that 54% of the peatlands have been drying and 32% have been wetting...

2022, Ecosphere (13)
Macroecology research seeks to understand ecological phenomena with causes and consequences that accumulate, interact, and emerge across scales spanning several orders of magnitude. Broad-extent, fine-grain information (i.e., high spatial resolution data over large areas) is needed to adequately capture these cross-scale phenomena, but these data have...
Predicting physical and geomorphic habitat associated with historical lake whitefish and cisco spawning locations in Lakes Erie and Ontario
Hannah M Schaefer, Andrew Edgar Honsey, David Bunnell, Brian C. Weidel, Robin DeBruyne, James S. Diana, Dimitry Gorsky, Edward F. Roseman
2022, Journal of Great Lakes Research (48) 1636-1646
The Great Lakes basin was historically populated by multiple, coevolved coregonine species, but much of that diversity has been lost. In Lakes Erie and Ontario, both lake whitefish (Coregonus clupeaformis) and cisco (Coregonus artedi) occurred in high numbers before habitat degradation, overfishing, invasive species, and other factors caused significant declines. There is growing...

Evaluation of Francisella orientalis ΔpdpA as a live attenuated vaccine against piscine Francisellosis in Nile tilapia
Fernanda de Alexandre Sebastião, John Hansen, Esteban Soto
2022, Journal of Aquatic Animal Health (34) 134-139
Francisella orientalis is an important bacterial pathogen of marine and freshwater fish with worldwide distribution. Fish francisellosis is a severe subacute to chronic granulomatous disease, with high mortalities and high infectivity rates in cultured and wild fish. To date, there is no approved vaccine for this disease. In this study, we...

Marine protected areas (MPAs), particularly large MPAs, are increasing in number and size around the globe in part to facilitate the conservation of marine megafauna under the assumption that large-scale MPAs better align with vagile life histories; however, this alignment is not well established. Using a global tracking dataset from...
Urbanization and stream ecology: Moving the bar on multidisciplinary solutions to wicked urban stream problems
Megan L. Fork, Kristina G. Hopkins, Jessica Chappell, Robert J. Hawley, Sujay S. Kaushal, Brian M. Murphy, Blanca Ríos-Touma, Allison H. Roy
2022, Freshwater Science (41)
Decades of research on the effects of urbanization on stream ecology have shown that urban stream problems are inherently wicked. These problems are wicked in the sense that they are difficult to solve because information is incomplete, changing, or conflicting and because finding potential solutions often requires input from stakeholders...

2022, Journal of Geophysical Research: Solid Earth (127)
In 2002 and 2003 a collaborative effort was undertaken between Lawrence Berkeley National Laboratory, Sandia National Laboratories, the U.S. Geological Survey (USGS) Menlo Park, the USGS Hawaiian Volcano Observatory, and Electromagnetic Instruments Inc. to study the Kīlauea volcano in Hawaii using the magnetotelluric (MT) technique. The work was motivated by...
GSPy: A new toolbox and data standard for Geophysical Datasets
Stephanie R. James, Nathan Leon Foks, Burke J. Minsley
2022, Frontiers in Earth Science - Environmental Informatics and Remote Sensing (10)
The diversity of geophysical methods and datatypes, as well as the isolated nature of various specialties (e.g., electromagnetic, seismic, potential fields) leads to a profusion of separate data file formats and documentation conventions. This can hinder cooperation and reduce the impact of datasets researchers have invested in heavily...

2022, Global and Planetary Change (216)
A paucity of detailed relative sea-level (RSL) reconstructions from low latitudes hinders efforts to understand the global, regional, and local processes that cause RSL change. We reconstruct RSL change during the past ~5 ka using cores of mangrove peat at two sites (Snipe Key and Swan...
Subsampling large-scale digital elevation models to expedite geospatial analyses in coastal regions
Kelly Ann Murphy, David G. Zawada, Kimberly K. Yates
2022, Journal of Coastal Research (38) 1236-1245
Large-area, high-resolution digital elevation models (DEMs) created from light detection and ranging (LIDAR) and/or multibeam echosounder data sets are commonly used in many scientific disciplines. These DEMs can span thousands of square kilometers, typically with a spatial resolution of 1 m or finer, and can be...

Geoffrey Phelps, Robert E. Bracken, John Spritzer, David S. White
2022, Journal of Applied Geophysics (206)
An uncrewed aerial vehicle (UAV) multirotor aeromagnetic system using a 5-m sling load for a magnetic sensor system is described and characterized. Four magnetic surveys with identical flight lines were completed, at two nominal altitudes of 25 and 40 m. The surveys were used to assess the repeatability of data collected...
Whole-ecosystem experiment illustrates short timescale hydrodynamic, light, and nutrient control of primary production in a terminal slough
Luke C. Loken, Steven Sadro, Leah Lenoch, Paul Stumpner, Randy A Dahlgren, Jon R. Burau, Erwin E Van Nieuwenhuyse
2022, Estuaries and Coasts (45) 2428-2449
Estuaries are among the most productive of aquatic ecosystems. Yet the collective understanding of patterns and drivers of primary production in estuaries is incomplete, in part due to complex hydrodynamics and multiple controlling factors that vary at a range of temporal and spatial scales. A whole-ecosystem experiment was conducted in...

Quantifying modeling uncertainty in simplified beam models for building response prediction
S. Farid Ghahari, Khachik Sargsyan, Mehmet Çelebi, Ertugrul Taciroglu
2022, Structural Control and Health Monitoring (29)
The use of simple models for response prediction of building structures is preferred in earthquake engineering for risk evaluations at regional scales, as they make computational studies more feasible. The primary impediment in their gainful use presently is the lack of viable methods for quantifying (and reducing upon) the modeling...
