Microbial mats in dinosaur ichnocoenoses

Sedimentology, EarlyView.
ABSTRACT Until now, the significance of microbial mats in preservation of dinosaur tracks and in reconstructing the palaeoenvironment in which dinosaurs roamed was rarely studied. Dinosaur tracks are commonly found close to ancient aquatic bodies where moist sediment had once allowed footstep registration.

Evaluating the possible role of bottom currents and internal waves in shaping seafloor morphology in a mesophotic reef

Sedimentology, EarlyView.
ABSTRACT Mesophotic reefs are located in low light conditions which, depending on the region, are usually found in water depths greater than ~30 m. They are less affected by ocean warming than reefs found in shallower water depths and thus might become increasingly important for the sustainability of marine biodiversity.

Variations in downslope activity and bottom current dynamics in a land‐detached submarine channel system since the Last Glacial Maximum

Sedimentology, EarlyView.
ABSTRACT The Gollum Channel System is a land‐detached large‐scale canyon‐channel system situated offshore southwest Ireland on the Northeast Atlantic margin. The system has been considered inactive with downslope gravity flows since the last glacial period, but geophysical data in some of its branches do suggest Holocene activity.

A review of the supercritical state of eruption‐fed volcanic density currents in subaerial and subaqueous settings

Sedimentology, EarlyView.
ABSTRACT Subaerial Pyroclastic Density Currents (PDCs) and Subaqueous Eruption‐Fed Density Currents (SEFDCs) produced during volcanic eruptions can present major hazards to surrounding communities and ecosystems. The bedforms deposited by these volcanic density currents can provide insights into the nature of transport and depositional processes, which

What is a Multi‐Ethnic Party and How to Spot a Fake One?

Swiss Political Science Review, EarlyView.
Abstract Multi‐ethnic parties have been variously defined: as those which do not champion the interests of, or mobilize against, any specific ethnic group; as those with a recognisably cross‐communal leadership or membership; and as those which acquire some distribution of support across groups.

Gully erosion in India: Geo‐environmental controls and region‐specific characteristics

Geographical Research, Volume 64, Issue 2, May 2026.
Spatial statistical analyses using a novel spatial database of India‧s gully erosion landforms revealed that India has six major gullying‐affected regions, three of which (EU, DU, and KCH) are dominated by gully systems (gully networks), with badlands (vast intensely gullied landscapes) being predominant in the other three regions (YB, GP, and RU ...

Taxonomic revision and conservation concerns of the trapezitine genus Croitana Waterhouse, 1932 (Lepidoptera: Hesperiidae) from Australia

Austral Entomology, Volume 65, Issue 2, May 2026.
Abstract Croitana Waterhouse, 1932 (Trapezitinae) is a small genus of skippers endemic to Australia, with most species restricted to semi‐arid and arid biomes where the larvae specialise on grasses (Poaceae) in the genera Neurachne R.Br., Enteropogon Nees and Austrostipa S.W.L. Jacobs & J.Everett.
