Space Weather, Volume 23, Issue 11, November 2025.Abstract A new daily composite of the solar flare index (SFI) and the hemispherically‐resolved versions (hSFI) are presented for 1937 to 2024. The data set confirms that the northern hemisphere (NH) dominated solar flare activity during Solar Cycles 17 to 21, but that the southern hemisphere has dominated from Solar Cycle 22 to present.

Diversity Hotspots and Vulnerability of Pine Species in the Sierra Madre Occidental, Western Mexico
Ecology and Evolution, Volume 15, Issue 7, July 2025.The present study employs a modeling approach to examine the current and future distribution of 19 pine species in the Sierra Madre Occidental, Mexico. This was done in order to identify areas with high potential for pine species richness and to determine which species are at risk due to climate change under different projections.

Tectonics, Volume 44, Issue 7, July 2025.Abstract Relamination is closely connected to subduction zones. Despite the numerous high‐P metamorphic belts recognized on Earth, relamination remains a poorly documented process. We present a continental subduction zone where the exhuming high‐P rocks became a relaminant under the upper plate.
