From distant shores to an emerging island: the role of surface and subsurface transport in modeling seed dispersal

Ecography, EarlyView.
Long‐distance seed dispersal by ocean currents plays a critical role in structuring coastal plant communities. As direct observations of this phenomenon are infeasible, numerical modeling is a valuable tool. Here, we use Lagrangian particle tracking to examine the colonization of the newly forming island Norderoogsand (German Bight, Wadden Sea) by five

THE CURRENT STATE OF THE THEORY OF PC1 RANGE ULF PULSATIONS IN MAGNETOSPHERIC PLASMA WITH HEAVY IONS: A REVIEW

Solar-Terrestrial Physics, 2022
The review considers the current state of the theory of short-period ULF waves in plasma with admixture of heavy ions (ions whose mass significantly exceeds the mass of protons).

Reflections of Swedish Fathers in Late Adulthood on Their Past and Present Parental Role in Relation to the Mother

Scandinavian Journal of Psychology, EarlyView.
ABSTRACT With a contextual and developmental perspective, this study aimed to examine Swedish late‐adult fathers' reflections on their past and present parental role in relation to the mother and to see how these reflections incorporate changes in gender and parenthood during recent decades in Sweden.

Simulation of radiation belt wave-particle interactions in an MHD-particle framework

Frontiers in Astronomy and Space Sciences, 2023
In this paper we describe K2, a comprehensive simulation model of Earth’s radiation belts that includes a wide range of relevant physical processes. Global MHD simulations are combined with guiding-center test-particle methods to model interactions with ...

Bounce Resonance Between ULF Waves and Electrons in the Dayside Outer Magnetosphere

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Resonant interactions between ultra‐low‐frequency (ULF) waves and particles are critical for energy transfer in the Earth's magnetosphere, and have been extensively investigated in the inner magnetosphere. However, resonant processes between ULF waves and electrons in the dayside outer magnetosphere remain largely unexplored.

Range finding of Alfvén oscillations and direction finding of ion-cyclotron waves by using the ground-based ULF finder [PDF]

, 1996
International audienceA new approach to the problem of direction and distance finding of magnetospheric ULF oscillations is described. It is based on additional information about the structure of geoelectromagnetic field at the Earth's surface which is ...

Modulation of Whistler-mode Waves in the Solar Wind in the Vicinity of Earth’s Moon

The Astrophysical Journal
Ultra-low-frequency (ULF) waves are known to modulate high-frequency whistler-mode waves within the Earth’s magnetosphere. Periodic bursts of whistler-mode waves are excited in association with ULF perturbations of plasma density and magnetic field.
