Magnetotail-Inner Magnetosphere Transport Associated With Fast Flows Based on Combined Global-Hybrid and CIMI Simulation
(2022-11-01)
Using the combined Auburn global hybrid simulation code in 3-D (ANGIE3D) and the Comprehensive Inner Magnetosphere-Ionosphere (CIMI) model, we investigate the self-consistent connection of fast flow injections from the ...
Magnitude and Predictability of pH Fluctuations Shape Plastic Responses to Ocean Acidification
(2023-06-17)
Phenotypic plasticity is expected to facilitate the persistence of natural populations as global change progresses. The attributes of fluctuating environments that favor the evolution of plasticity have received extensive ...
Maskelynite formation via solid-state transformation: Evidence of infrared and X-ray anisotropy
(2020-06-05)
We present the results of a combined study of shocked labradorite from the Lonar crater, India, using optical microscopy, micro-Raman spectroscopy, nuclear magnetic resonance (NMR) spectroscopy, high-energy X-ray total ...

MATERNAL TRAITS AND REPRODUCTION IN RICHARDSONS GROUND-SQUIRRELS
(2022-12-06)
Differences among conspecifics in body mass result from underlying differences in structural size and physiological condition. To determine whether the structural or physiological component of body mass has a stronger ...
Micro- and Macroevolutionary Trade-Offs in Plant-Feeding Insects
(2023-05-17)
A long-standing hypothesis asserts that plant-feeding insects specialize on particular host plants because of negative interactions (trade-offs) between adaptations to alternative hosts, yet empirical evidence for such ...
Modeling of a New Electron Acceleration Mechanism Ahead of Streamers
(2020-05-26)
Head‐on collisions between negative and positive streamers have been proposed as a mechanism behind X‐ray emissions by laboratory spark discharges. Recent simulations using plasma fluid and particle in cell models of a ...

Modeling the Dynamics of Radiation Belt Electrons With Source and Loss Driven by the Solar Wind
(2022-11-16)
A radial diffusion model directly driven by the solar wind is developed to reproduce MeV electron variations between L = 2-12 (L is L* in this study) from October 2012 to April 2015. The radial diffusion coefficient, ...

Recent satellite observations, combined with instability analyses, have shown that the background plasma density variation can modulate the magnetosonic (MS) waves by controlling the wave excitation. However, the detailed ...
Molecular genetic evidence that dinoflagellates belonging to the genus Symbiodinium freudenthal are haploid
(2019-08-02)
Microscopic and cytological evidence suggest that many dinoflagellates possess a haploid nuclear phase. However, the ploidy of a number of dinoflagellates remains unknown, and molecular genetic support for haploidy in this ...
Molecular responses of brains to cross-generational warming in a coral reef fish.
(2021-12-17)
Ocean warming is a threat to marine biodiversity, as it can push marine species beyond their physiological limits. Detrimental effects can occur when marine poikilotherms are exposed to conditions beyond their optimal ...
