Ecological Research, Volume 41, Issue 3, May 2026.Solar‐induced chlorophyll fluorescence (SIF) and gross primary productivity decline at midday during a short heatwave in a tower site of a larch forest. High atmospheric vapor pressure deficit significantly reduced the photochemical reflectance index (PRI), light‐use efficiency (LUE), and canopy fluorescence emission efficiency (εF).

New perspectives on the Popigai impact structure [PDF]
The record of large-scale cratering on Earth is scant, and the only currently 'proven' 100-km-class impact structure known to have formed within the Cenozoic is Popigai, located in the Siberian Arctic at 71.5 deg N, 111 deg E.

Enhancing Role of Nitrogen Fixation in Biogeochemical Cycles of the Pacific Arctic
Global Change Biology, Volume 32, Issue 5, May 2026.Composite mean fields of sea surface temperature and sea‐ice distribution for September during 2015–2024, comparing years with high (2015, 2016, 2021) and low (2017, 2019, 2023) sea‐ice coverage. Earlier sea‐ice melt can promote the advection of diazotrophs (UCYN‐A2 and their haptophyte hosts) from the Bering Sea into the Beaufort Sea basin, where ...

Molecular Ecology, Volume 35, Issue 10, May 2026.ABSTRACT Invasive plant species present a growing ecological and economic challenge, and often adapt rapidly to their novel environments through complex demographic and evolutionary processes. Invasion genomics offers powerful tools to disentangle these processes, but most studies rely on geographically narrow sampling across native and non‐native ...
