Polygonal tepee structures of Arabia

open access: yesThe 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 ...

Macroid Formation in Salmacina stellaebayensis n. sp. From Mauritania's Baie de l'Étoile With New Insights on Mitogenome Evolution in Serpulidae (Annelida)

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
We describe Salmacina stellaebayensis n. sp. from Mauritania's Baie de l'Étoile and provide the first complete mitochondrial genome for the genus Salmacina. The species forms distinctive macroid colonies in Cymodocea nodosa seagrass meadows, offering new insights into serpulid life history and habitat specialization.
