Metatranscriptomics analysis of silicon transporters highlights underappreciated contributors to silica cycling in the Baltic Sea

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract The biotic component of the marine silica cycle strongly influences global biogeochemical cycling. Active uptake of dissolved silicic acid (dSi) occurs via silicon transporters (SITs), first characterized in diatoms but widely distributed in eukaryotes. Studying SITs and SIT‐like (SIT‐L) gene transcripts provides insights into the dynamics and

Spiniferites cruciformis: a fresh water dinoflagellate cyst?

Review of Palaeobotany and Palynology, 2001
Palynological studies of cored lacustrine sediments from the late Quaternary of Lake Kastoria, northern Greece, revealed a Late Glacial interval with abundant dinoflagellate cysts. Cyst assemblages include two identifiable species, Spiniferites cruciformis and Gonyaulax apiculata. The presence of the fresh water species G.

A southern North Sea Miocene dinoflagellate cyst zonation [PDF]

Netherlands Journal of Geosciences - Geologie en Mijnbouw, 2004
AbstractAn integrated stratigraphical analysis emphasizing organic-walled dinoflagellate cyst (dinocyst) distribution has been carried out on multiple boreholes penetrating the Miocene in the subsurface of the Netherlands (southern North Sea Basin).

Cenozoic foraminiferal and dinoflagellate cyst biostratigraphy of the Central North Sea [PDF]

, 1992
We present a detailed Cenozoic biostratigraphy for Paleogene bathyal and Neogene ncritic strata, north of 55° in the central North Sea, and offshore mid-Norway, using both forarninifera and dinoflagellate cysts. Construction of the zonations was assisted

First evidence of Campanian-Maastrichtian shallow marine deposits from eastern Atlantic margin (Doualasub-basin, Cameroon): Palynological and sedimentological approaches

Geosystems and Geoenvironment
Integration of facies analysis with organic microfossils (mainly dinoflagellate cysts) provides insights into the paleoenvironmental reconstruction of the onshore part of the Douala sub-basin of Cameroon.

Bipolar distribution of the cyst-forming dinoflagellate Polarella glacialis [PDF]

Polar Biology, 2003
Morphological investigations of motile cells and cysts of a small dinoflagellate (strain CCMP 2088) isolated from Canadian Arctic waters were carried out under both light and scanning electron microscopy. This species strongly resembled Polarella glacialis (strain CCMP 1383), which up to now was known only from Antarctic sea ice.

Sedimentary Ancient DNA Tracks Multi‐Kingdom Ecosystem Reorganizations Following Sequential Human Land Use at Crawford Lake

Molecular Ecology, Volume 35, Issue 17, September 2026.
ABSTRACT Crawford Lake has an exceptional stratigraphic record that began recording biannual (varved) sedimentation in the lake basin ~750 years ago, preserving evidence of shifting cultural zones and agricultural practices, from Late Woodland Period Indigenous agriculturalists to the impacts of industrialization during the late 19th century.
