Interplay Between River Formation and Historical Climatic Changes Drove Diversification of the Thamnomanes caesius and T. schistogynus (Passeriformes, Thamnophilidae) Species Complex Across Amazonian and Atlantic Forests

open access: yesZoologica Scripta, Volume 55, Issue 4, Page 555-567, July 2026.
ABSTRACT The Amazon and Atlantic forests harbour immense biodiversity shaped by complex evolutionary history with diverse processes leading to species build‐up. We investigated the Cinereous Antshrike species complex (Thamnomanes caesius and T. schistogynus) to disentangle the relative contributions of riverine barriers and historical climatic ...

Alaskan Ridge Blocking and Associated Winter Cold Conditions Over North America

open access: yesInternational Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
Multi‐decadal (1979–2023) analysis reveals that wintertime reductions in the meridional gradient of potential vorticity (PVy) over the Bering Sea are recurrent but episodic features of North Pacific circulation. These suppressed PVy states consistently co‐occur with amplified Alaskan ridging, weakened mid‐tropospheric westerlies and a downstream warm ...

Spatiotemporal Evolution of Hydroclimatic Variables in the Brazilian Semi‐Arid Region Through the Aridity Index and Susceptibility to Desertification

open access: yesInternational Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
Over the past 60 years, noticeable changes have been observed in the main hydroclimatological variables, driven by both natural and anthropogenic factors. In the context of climate change, such behaviour may adversely affect the state's economic activities, as well as increase the recurrence of extreme events in the region.

Weather Patterns Associated With Coastal Disasters in Santa Catarina, Southern Brazil

open access: yesInternational Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
The study identified weather patterns (WPs) associated with coastal disasters between 1998 and 2020 along the Santa Catarina coast, Brazil. Using atmospheric and oceanographic data combined with official disaster records, five WPs were defined, mainly associated with cyclonic and anticyclonic systems linked to extreme wave events.
