Mechanisms underlying the loss of migratory behaviour in a long‐lived bird

Journal of Animal Ecology, Volume 94, Issue 5, Page 1061-1075, May 2025.
White stork populations in Iberia are undergoing a profound change in their migratory patterns, becoming mostly resident. By combining census data, GPS‐tracking and genomic analyses, Andrade et al. link this behavioural change to inter‐generational shifts in the frequency of migratory and non‐migratory young individuals (likely associated with ...

Multi‐isotope (N, O, Ti, and Cr) study of C1 and CM‐like clasts—Probing unsampled C1 material

Meteoritics &Planetary Science, Volume 60, Issue 5, Page 1073-1094, May 2025.
Abstract A multi‐element isotope (N, O, Ti, and Cr) study was conducted on C1 and CM‐like clasts hosted in achondrites and chondrite breccias to understand the genesis of these chondritic clasts. The mineralogy, O, and N isotopes confirm that CM‐like clasts in howardites and polymict eucrites closely resemble CM chondrite‐like material.

Comparison of Solar Energetic Particle Flux Measurements by CRaTER and GOES

Space Weather, Volume 23, Issue 4, April 2025.
Abstract The Cosmic Ray Telescope for the Effects of Radiation (CRaTER) aboard the Lunar Reconnaissance Orbiter spacecraft has been operating in lunar orbit since 2009. CRaTER data provide a long‐term record of the near‐Moon radiation environment that is relevant to human exploration.

Neutrino oscillations in magnetically driven supernova explosions

, 2009
We investigate neutrino oscillations from core-collapse supernovae that produce magnetohydrodynamic (MHD) explosions. By calculating numerically the flavor conversion of neutrinos in the highly non-spherical envelope, we study how the explosion ...

Interpretation of AMS-02 electrons and positrons data

, 2014
We perform a combined analysis of the recent AMS-02 data on electrons, positrons, electrons plus positrons and positron fraction, in a self-consistent framework where we realize a theoretical modeling of all the astrophysical components that can ...

The diffuse supernova neutrino flux, supernova rate and SN1987A

, 2006
I calculate the diffuse flux of electron antineutrinos from all supernovae using the information on the neutrino spectrum from SN987A and the information on the rate of supernovae from direct supernova observations.
