Solar Flare Activity, 1937–2024: Introducing the New Hemispheric Solar Flare Index (hSFI) in the Context of 2024's Major Solar Storm Events

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.

Variabilidad en la frecuencia de los huracanes del Caribe en octubre durante el período 1951-2005

Revista Cubana de Meteorología, 2009
En esta investigación se retoma el tema de los huracanes, pero esta vez sólo para el Mar Caribe y en el mes de octubre; es decir se intenta explicar las variaciones que ocurren de forma interdecadal en la frecuencia de formación e intensificación de los ...

Impact of endometrial thickness on reproductive outcome in fresh and frozen–thawed embryo transfer: systematic review and meta‐analysis

Ultrasound in Obstetrics &Gynecology, Volume 66, Issue 3, Page 271-281, September 2025.
ABSTRACT Objective To evaluate the impact of endometrial thickness on the reproductive outcomes of embryo transfer (ET) treatments using both cut‐off‐based meta‐analysis and meta‐analysis of proportions. Methods This was a systematic review and meta‐analysis of comparative studies (randomized controlled trials, cohort studies, case–control studies) and

Spatially nested species distribution models (N‐SDM): An effective tool to overcome niche truncation for more robust inference and projections

Journal of Ecology, Volume 113, Issue 7, Page 1588-1605, July 2025.
N‐SDMs are key tools to develop untruncated regional climate change forecasts of species distributions at fine resolution over restricted extents. While several N‐SDM approaches were proposed, there is currently no universal solution suggesting that further developments and testing are crucial if we are to derive robust future projections of species ...

Spatio‐Temporal Representation of Mesoscale Convective Systems in Convection‐Permitting Simulations Over Northwestern South America: Insights Into Rainfall Overestimation

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 7, 16 April 2025.
Abstract We perform km‐scale convection‐permitting simulations (Δx = 4 km) to represent Mesoscale Convective Systems (MCSs) in Northwestern South America using the Weather Research and Forecasting (WRF) model. An algorithm to identify and track MCSs was used to characterize simulated MCS features and compare with satellite observations.

COSST: A tool to facilitate seed provenancing for climate‐smart ecosystem restoration

Journal of Applied Ecology, Volume 62, Issue 3, Page 677-688, March 2025.
Our tool can guide where to source seeds for species lacking range‐wide information on genetic structure, which is the case for a substantial proportion of the tropical flora, where ecosystem restoration is of paramount importance. Abstract Selecting the best seed sources is a key step in ecological restoration planning especially under climate change.
