Sediment‐stressed reefs over the past 420 Myr
The Depositional Record, Volume 12, Issue 1, February 2026.In order to fully elucidate the relationship between siliciclastic sedimentation and reef development, there needs to be a significant step change in how we record ancient and recent reefs. Only through the collection of constrained quantitative data, we can progress beyond the largely conjectural associations postulated for many ancient reefal systems.

Polygonal tepee structures of Arabia
The Depositional Record, Volume 12, Issue 1, February 2026.Tepee structures on Sheybarah Island form polygonal microbial cemented crusts in the intertidal. Radiocarbon dating suggests they formed in the Holocene and reflect minor sea‐level changes, highlighting their value as palaeoenvironmental indicators. Satellite surveys identified 126 polygonal features, including coral reefs that may have developed on ...

The Depositional Record, Volume 12, Issue 1, February 2026.Using machine learning, researchers can count and crudely identify sand grains from coral reefs automatically. This will allow us to generate larger datasets to answer sedimentological questions. Abstract Sediment is an important facet of sand cay reefs as it is responsible for reef accretion and island formation, with shifts in the proportions of ...

The Depositional Record, Volume 12, Issue 1, February 2026.We propose that one of the largest known bioconstructions (the Monte Zenone bioherm) in the Southern Alps, northern Italy, and its growth on a tilted and drowned platform block of the Norian Dolomia Principale was controlled by hydrothermal dolomitisation from fault‐controlled fluids during the Late Triassic–Early Jurassic rifting phase. Dolomitisation

Domed‐rim microbial polygons and their preservation potential
The Depositional Record, Volume 12, Issue 1, February 2026.Microbially induced sedimentary structures (MISS) derive through interactions between minerals and microorganisms. We define a domed‐rim MISS, morphologically distinct from abiotic mud cracks and demonstrate its potential for long‐term preservation. These structures represent promising biosignatures in ancient environments on Earth and potentially Mars.

Ecology and Evolution, Volume 16, Issue 2, February 2026.Two co‐occurring species of hermit crabs use very different shell sizes, one species using shells that are too small to accommodate all the carapace or claws. The two crab species were found to have diverged in their adaptations to their environment: one species adopting a suite of traits, including the use of large shells, that enhance protection from

Ecology and Evolution, Volume 16, Issue 2, February 2026.We reconstructed the speciation history of the recently split pseudocryptic nudibranch genus Hermissenda, finding divergence times in the Pleistocene (1.29–0.55 mya). Demographic modeling and behavioral experiments show no gene flow and assortative mating between sympatric species H. crassicornis (s.s.) and H.
