Ichnological insights into deoxygenation across the Cenomanian–Turonian Boundary Oceanic Anoxic Event 2 in the northern extent of Western Interior Seaway (west‐central Alberta)

Sedimentology, Volume 73, Issue 2, Page 355-390, February 2026.
ABSTRACT In‐depth ichnological and sedimentological analyses of the Cenomanian–Turonian boundary Oceanic Anoxic Event (OAE2) from the Western Interior Seaway of west‐central Alberta reveal a persistent physico‐chemically stressed setting. The interval is characterised by a dominantly diminutive and diminished ichnological assemblage, with familiar ...

Palaeoecological and possible evolutionary effects of early Namurian (Serpukhovian, Carboniferous) glacioeustatic cyclicity [PDF]

, 2008
Early Namurian (Serpukhovian, Carboniferous), sedimentary cycles in the Throckley and Rowlands Gill boreholes, near Newcastle upon Tyne, UK, consist of fossiliferous limestones overlain by (usually unfossiliferous) black mudstone, followed by sandstones ...

The Soil Erosion Paradox Re‐Examined: Alluviation and Land Use History in a Small British Lowland River Catchment in the Late Holocene

Geoarchaeology, Volume 41, Issue 1, January/February 2026.
ABSTRACT Modern studies show that soil erosion results in a loss of ecosystem function, particularly fertility, and is a cause of declining agricultural yields. However, despite the well‐attested high rates of soil erosion across Roman and medieval Europe there appears to have been little or no soil‐associated decline in agricultural production—the ...

An early Little Ice Age brackish water invasion along the south coast of the Caspian Sea (sediment of Langarud wetland) and its wider impacts on environment and people [PDF]

, 2015
Caspian Sea level has undergone significant changes through time with major impacts not only on the surrounding coasts, but also offshore. This study reports a brackish water invasion on the southern coast of the Caspian Sea constructed from a multi ...

Unusual biota and palynofacies of a Lower Devonian intermontane basin saline lake–playa mudflat ecosystem

Papers in Palaeontology, Volume 12, Issue 1, January/February 2026.
Abstract The Strathpeffer–Struie Lower Devonian LORS (Lower Old Red Sandstone) deposits of the Northern Highlands of Scotland contain the decidedly unusual ‘foetid beds’. These are interpreted as being deposited in a highly saline sulphate lake and associated playa mudflat, which developed in an intermontane basin in the Caledonian Mountains of ...

The role of microclimate in supporting peatlands as climate‐change refugia: A Central European perspective

Conservation Science and Practice, Volume 8, Issue 1, January 2026.
Some peatlands in Central Europe serve as continuous refugia for glacial species, as shown by paleoecological data. However, the ecosystem mechanisms behind this are not well understood. Microclimate plays a key role, and understanding the factors shaping it is crucial for managing peatlands as climate‐change refugia.
