Physico-chemical and biological factors influencing dinoflagellate cyst production in the Cariaco Basin [PDF]

Biogeosciences, 2018
We present a 2.5-year-long sediment trap record of dinoflagellate cyst production in the Cariaco Basin, off Venezuela (southern Caribbean Sea). The site lies under the influence of wind-driven, seasonal upwelling which promotes high levels of primary ...

Ecological Processes Shaping Marine Microbial Assemblages Diverge Between Equatorial and Temperate Time‐Series

Molecular Ecology, Volume 35, Issue 2, January 2026.
ABSTRACT Marine microbial communities are structured by a complex interplay of deterministic and stochastic processes, yet how these vary across latitudes remains poorly understood. Most long‐term microbial observatories are restricted to temperate regions, limiting our ability to assess latitudinal contrasts in microbial dynamics.

Global Warming Affects the Pathogenesis of Important Fish Diseases in European Aquaculture

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
The effect of global warming on pathogens and their fish hosts that could exacerbate the negative outcomes for aquaculture. Changes in farming practices and the development of innovative mitigation tools may prove essential to cope with the effects and impacts of rising water temperatures on fish diseases in Europe.

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.

Regulatory network rewiring drives strain‐specific lipid accumulation response in Chlorella sorokiniana under nutrient starvation

The Plant Journal, Volume 125, Issue 1, January 2026.
SUMMARY Microalgae modulate lipid metabolism in response to nutrient stress, offering a promising avenue for sustainable biofuel production. However, a mechanistic understanding of the transcriptional programs driving triacylglycerol (TAG) accumulation remains limited, particularly in non‐model species.

Modulation of ecdysal cyst and toxin dynamics of two Alexandrium (Dinophyceae) species under small-scale turbulence [PDF]

, 2007
Some dinoflagellate species have shown different physiological responses to certain turbulent conditions. Here we investigate how two levels of turbulent kinetic energy dissipation rates (epsilon = 0.4 and 27 cm(2) s(-3)) affect the PSP toxins and ...

Dinoflagellate cysts from the Bathonian – Tithonian (Jurassic) of North Bulgaria. III. Tithonian dinoflagellate cysts

Geologica Balcanica, 1994
Tithonian marine sediments from 34 boreholes and one outcrop in North Bulgaria have been palynologically examined. They contain rich anа commonly well preserved dinocyst assemblages. This paper includes brief comments on morphology, taxonomy, geographic and stratigraphic distribution of 56 dinocyst taxa and 2 acritarch species which start ill this ...

Transcriptomic Insights Into the Immune Repertoire of an Antarctic Sponge

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Antarctic marine sponges are essential components of the benthic fauna, playing a crucial role in structuring this ecosystem through their own biological activities and their symbiotic relationships with diverse microorganisms. Yet, the transcriptional repertoire and the immune responses associated with interactions with microorganisms in this unique ...
