Magnetic field rotation and transition width in rotational discontinuities and Alfven wave trains
(2020-06-30)
A hybrid simulation is carried out to study the evolution of magnetic field rotations in rotational discontinuities (RDs) and large-amplitude Alfven wave trains (AWTs) whose initial field rotation angle \Delta Phi\ > 180 ...
Magnetic flux rope formation within a magnetosheath hot flow anomaly
(2020-06-09)
We report observations on 1 March 2004 by the Cluster spacecraft of a hot flow anomaly (HFA) encountered in the dayside magnetosheath near Earth's bow shock. Embedded within the HFA was a magnetic flux rope with a diameter ...
Magnetic Reconnection Inside Solar Wind Rotational Discontinuity During Its Interaction With the Quasi-Perpendicular Bow Shock and Magnetosheath

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 ...

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 ...
