The landscape in Mars Transverse Mercator (MTM) −10022 and −15022 quadrangles (lat −7.5° N. to −17.5° N. between long 335° E. and 340° E.) in Margaritifer Terra preserves a record of sedimentary and alluvial deposits, volcanic and tectonic structures, and erosional landforms that record a long and complex geologic and...
Expression plasticity regulates intraspecific variation in the acclimatization potential of a reef-building coral
Crawford Drury, Jenna Dilworth, Eva Majerová, Carlo Caruso, Justin Blaine Greer
2022, Nature Communications (13)
Phenotypic plasticity is an important ecological and evolutionary response for organisms experiencing environmental change, but the ubiquity of this capacity within coral species and across symbiont communities is unknown. We exposed ten genotypes of the reef-building coral Montipora capitata with divergent symbiont communities to four thermal pre-exposure profiles and quantified gene expression...
Vote-processing rules for combining control recommendations from multiple models
William J.M. Probert, Sam Nicol, Matthew J. Ferrari, Shou-Li Li, Katriona Shea, Michael J. Tildesley, Michael C. Runge
2022, Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences (380)
Mathematical modelling is used during disease outbreaks to compare control interventions. Using multiple models, the best method to combine model recommendations is unclear. Existing methods weight model projections, then rank control interventions using the combined projections, presuming model outputs are directly comparable. However, the way each model represents the epidemiological...
The abundance and persistence of Caprinae populations
Grant M. Harris, Matthew J. Butler, David R. Stewart, James W. Cain III
2022, Scientific Reports (12)
Stable or growing populations may go extinct when their sizes cannot withstand large swings in temporal variation and stochastic forces. Hence, the minimum abundance threshold defining when populations can persist without human intervention forms a key conservation parameter. We identify this threshold for many populations of Caprinae,...

2022, Animals (12)
In the coastal region of Washington State, a major pathogen emergence event occurred between 2007 and 2011 in which steelhead trout (Oncorhynchus mykiss) experienced a high incidence of infection and disease outbreaks due to the rhabdovirus infectious hematopoietic necrosis virus (IHNV). Genetic typing showed that the...

Brittle faulting at elevated temperature and vanishing effective stress
Nicholas M. Beeler
2022, JGR Solid Earth (127)
If brittle fault strength depends only on friction, slip instability is discouraged at low effective normal stress, σ. Stress drop and the critical stiffness necessary for unstable sliding both vanish with σ; small earthquakes cannot occur. Very low σ is inferred in the source region of low-frequency earthquakes (LFEs) on the San Andreas fault...

Sarah M Wenner, Melanie A. Murphy, Kathleen Semple Delaney, Gregory B. Pauly, Jonathan Q. Richmond, Robert N. Fisher, Jeanne M. Robertson
2022, Molecular Ecology (31) 5214-5230
Identifying how natural (i.e., unaltered by human activity) and anthropogenic landscape variables influence contemporary functional connectivity in terrestrial organisms can elucidate the genetic consequences of environmental change. We examine population genetic structure and functional connectivity among populations of a declining species, the Blainville's horned lizard (Phrynosoma...
Could Kı̄lauea's 2020 post caldera-forming eruption have been anticipated?
Paul Segall, Kyle R. Anderson, Taiyi Wang
2022, Geophysical Research Letters (49)
In 2018 Kīlauea volcano erupted a decade’s worth of basalt, given estimated magma supply rates, triggering caldera collapse. Yet, less than 2.5 years later Kīlauea re-erupted. At the 2018 eruption onset, pressure within the summit reservoir was ~20 MPa above magmastatic. By the onset of collapse this decreased by ~17...

Plague and trace metals in natural systems
Michael Kosoy, Dean E. Biggins
2022, International Journal of Environmental Research and Public Health. (19)
All pathogenic organisms are exposed to abiotic influences such as the microclimates and chemical constituents of their environments. Even those pathogens that exist primarily within their hosts or vectors can be influenced directly or indirectly. Yersinia pestis, the flea-borne bacterium causing plague, is influenced by climate and its survival in...
Quantifying large-scale surface change using SAR amplitude images: Crater morphology changes during the 2019-2020 Shishaldin Volcano eruption
Mario Angarita, Ronni Grapenthin, Simon Plank, Franz Meyer, Hannah R. Dietterich
2022, Journal of Geophysical Research - Solid Earth (127)
Morphological processes often induce meter-scale elevation changes. When a volcano erupts, tracking such processes provides insights into the style and evolution of eruptive activity and related hazards. Compared to optical remote-sensing products, synthetic aperture radar (SAR) observes surface change during inclement weather and at night. Differential SAR...

Kirsty E. B. Gurney, Joshua C. Koch, Joel A. Schmutz, J. H. Schmidt, Mark S. Wipfli
2022, Freshwater Biology (67) 1832-1844
Ongoing environmental change across the Arctic is affecting many freshwater ecosystems, including small thaw ponds that support macroinvertebrates, thus potentially affecting important forage for fish and bird species. To accurately predict how fish and wildlife that depend on these macroinvertebrates will be affected by ecosystem change at high latitudes,...

Harry J. Dowsett, Peter Jacobs, Kim de Mutsert
2022, Frontiers in Ecology and Evolution (10)
Latest climate models project conditions for the end of this century that are generally outside of the human experience. These future conditions affect the resilience and sustainability of ecosystems, alter biogeographic zones, and impact biodiversity. Deep-time records of paleoclimate provide insight into the climate system over millions of years and...

One shell of a problem: Cumulative threat analysis of male sea turtles indicates high anthropogenic threat for migratory individuals and Gulf of Mexico residents
Micah Ashford, James I. Watling, Kristen Hart
2022, Remote Sensing (14)
Human use of oceans has dramatically increased in the 21st century. Sea turtles are vulnerable to anthropogenic stressors in the marine environment because of lengthy migrations between foraging and breeding sites, often along coastal migration corridors. Little is known about how movement and threat interact specifically for...

Nicholas Enwright, Kelly M. Darnell, Greg A. Carter
2022, Landscape Ecology (37) 2689-2705
ContextSeagrasses are submerged marine plants that have been declining globally at increasing rates. Natural resource managers rely on monitoring programs to detect and understand changes in these ecosystems. Technological advancements are allowing for the development of patch-level seagrass maps, which can be used to explore seagrass meadow spatial...
