Treasures of the Serra da Jiboia (Bahia, Brazil): a new species of Racinaea and an overview of the local Bromeliaceae flora

open access: yesNordic Journal of Botany, Volume 2026, Issue 10, October 2026.
Serra da Jiboia, located in the south‐central region of Bahia, represents an important ecotone between the Atlantic Forest and the Caatinga and harbors high floristic diversity and numerous endemic species. The Bromeliaceae family, well represented in the region, stands out for its ecological importance and adaptability to various microenvironments ...

Mesoclimatic origin affects alpine plant germination but not its plasticity

open access: yesOikos, Volume 2026, Issue 10, October 2026.
Mountain ecosystems are disproportionately exposed to global warming, which may put alpine plant species in particular at risk. Plant species' migration and persistence depend on successful seed regeneration, with demographic traits such as germination being strongly sensitive to both present and ancestral climate.

Modeled Subsidence of Permafrost Terrain 2025–2050: North‐Central Alaska

open access: yesPermafrost and Periglacial Processes, Volume 37, Issue 4, Page 692-712, October/December 2026.
ABSTRACT A large fraction of the Alaska terrain is underlain by regolith that contains excess ice (ice that in volume exceeds the natural pore space). Possible loss of excess ice would lead to ground subsidence, which in turn would disturb and destabilize the ground surface.

Disposition Model for Permafrost Degradation in Mountainous Regions

open access: yesPermafrost and Periglacial Processes, Volume 37, Issue 4, Page 592-609, October/December 2026.
ABSTRACT Permafrost is a widespread thermal phenomenon in Arctic and high mountain regions that, in combination with steep terrain, exerts a key control on slope stability. Its degradation in response to climatic warming can modify the likelihood and timing of rockfall, debris flow and related mass movements. Robust information on the current state and

Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin

open access: yesPermafrost and Periglacial Processes, Volume 37, Issue 4, Page 623-644, October/December 2026.
ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.
