Microfabric controls on the preservation and erosion of Late Pleistocene freshwater microbialites in northwestern Patagonia, Argentina

open access: yesThe Depositional Record, Volume 12, Issue 4, September 2026.
Microfabric distribution controls porosity, preservation and erosion in Late Pleistocene microbialites from the Maquinchao Basin (Argentina). Differential preservation of laminated and shrub fabrics shapes the present morphology of the carbonate build‐ups and influences their palaeoenvironmental interpretation.

Unearthing Forest History: Integrating Soil Charcoal Macrofossils and Pollen Reveals Delayed Forest Responses to Holocene Climatic Transitions in Boreal–Temperate Ecotone

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
This study reconstructs long‐term vegetation dynamics at the boreal–temperate forest ecotone in eastern Canada using soil charcoal, pollen records, and forest inventories. Results reveal a delayed expansion of thermophilous tree species and a late borealization of the landscape in relation to climate change, alongside recent stand‐scale shifts driven ...

Multi‐Hazard Shaking‐Tsunami Fatality Risk Estimation for Coastal Communities

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2618-2633, September 2026.
ABSTRACT This study develops a multi‐hazard fatality risk model for a coastal community (Tofino) on Vancouver Island, Canada, subjected to earthquake‐tsunami threats from the Cascadia subduction megathrust events. The model incorporates variable population distributions and uncertain fatality rate models, in addition to other key model components, such

Peatlands at Southernmost Permafrost Edge: Rapid Carbon Accumulation but High Vulnerability to Drying

open access: yesGlobal Change Biology Communications, Volume 1, Issue 3, September 2026.
Little Ice Age cooling promoted peat initiation and permafrost development at the southern permafrost margin. Rapid carbon accumulation was sustained by permafrost‐suppressed decay and high photosynthetically active radiation, but recent warming‐driven drying is reducing carbon accumulation and increasing carbon‐loss risk.
