Nocturnal incubation recess and flushing behavior by duck hens

open access: yesEcology and Evolution, 2021
Incubating birds must balance the needs of their developing embryos with their own physiological needs, and many birds accomplish this by taking periodic breaks from incubation.

Comparing Root Cohesion Estimates from Three Models at a Shallow Landslide in the Oregon Coast Range

open access: yesGeoHazards, 2022
Although accurate root cohesion model estimates are essential to quantify the effect of vegetation roots on shallow slope stability, few means exist to independently validate such model outputs.

Multi‐scale patterns in the occurrence of an ephemeral pool‐breeding amphibian

open access: yesEcosphere, 2022
Species distributions are governed by processes occurring at multiple spatial scales. For species with complex life cycles, the needs of all life stages must be met within the dispersal limitations of the species.

Nonlinear Radiation Damping: A New Method for Dissipating Energy in Dynamic Earthquake Rupture Simulations

open access: yesThe Seismic Record, 2023
Dynamic earthquake rupture simulations are used to understand earthquake mechanics and the ground shaking that earthquakes produce. These simulations can help diagnose past earthquake behavior and are also used to generate scenarios of possible future ...

Annual Recurrences of Viral Hemorrhagic Septicemia Epizootics in Age 0 Pacific Herring Clupea pallasii Valenciennes, 1847

open access: yesAnimals, 2021
Throughout a 20 year biosurveillance period, viral hemorrhagic septicemia virus was isolated in low titers from only 6/7355 opportunistically sampled adult Pacific herring, reflecting the typical endemic phase of the disease when the virus persists ...

S/P Amplitude Ratios Derived from Single-Component Seismograms and Their Potential Use in Constraining Focal Mechanisms for Microearthquake Sequences

open access: yesThe Seismic Record, 2022
Focal mechanisms, which reflect the sense of slip in earthquakes, provide important constraints for understanding crustal tectonics and earthquake source physics, including the interactions among earthquakes during mainshock–aftershock sequences or ...

Sierra Nevada amphibians demonstrate stable occupancy despite precipitation volatility in the early 21st Century

open access: yesFrontiers in Ecology and Evolution, 2023
Climate can have a strong influence on species distributions, and amphibians with different life histories might be affected by annual variability in precipitation in different ways. The Sierra Nevada of California, United States, experienced some of the

Fracture‐Mesh Faulting in the Swarm‐Like 2020 Maacama Sequence Revealed by High‐Precision Earthquake Detection, Location, and Focal Mechanisms

open access: yesGeophysical Research Letters, 2023
In August of 2020, an earthquake sequence initiated within the Maacama fault zone in northern California, raising questions about its relationship with the larger‐scale fault.
