Our findings reveal a marked increase in both the frequency and spatial extent of CMTHWs over the past four decades.

Atmospheric processes cause additional land surface warming relative to the ocean. Specifically, during CMTHWs, land surface latent heat flux anomalies are significantly larger than those over the ocean, highlighting the critical role of atmospheric feedback.

This study focused on the sex-dependent influence of Artificial Light at Night on food consumption rates and absorption efficiency in males and females of the non-indigenous amphipod <em>Ampithoe valida</em>. Males and females were exposed to two light treatments: a natural light/dark cycle and Artificial Light at Night.

Results showed that females had higher nocturnal food consumption rates under control conditions, while males showed no significant diel food consumption rates. Under Artificial Light at Night conditions, females experienced a substantial reduction in nighttime food consumption rates and absorption efficiency, suggesting stress or disrupted circadian rhythms. In contrast, males increased their nighttime food consumption rates under Artificial Light at Night, possibly exploiting a new light-induced niche.
