Diatoms–copepods: An evolutionary arms race

Limnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Diatoms and copepods are dominating and diverse groups of phytoplankton and zooplankton, respectively. Diatoms account for 25–40% of ocean primary production, and their main predators, copepods, are arguably the most abundant group of metazoans in the ocean, typically accounting for ~ 80% of zooplankton biomass.

Biostratigrafie spodní křídy manínské jednotky (lom Butkov, Strážovské vrchy, Západní Karpaty) [PDF]

, 2003
This paper is a continuation of systematic stratigraphical research of Lower Cretaceous sequence of the Manín Unit excavated in the Butkov quarry. Calcareous deposits are significant especially by richness of ammonites.

Decadal shifts in hypoxia and acidification reveal changing anthropogenic pressures on bottom waters of a coastal shelf

Limnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract Coastal systems provide habitat that sustains valuable shellfisheries but are subject to dissolved oxygen (DO) and/or carbonate chemistry impairment from anthropogenic pressures such as eutrophication and increasingly, climate change. Although extreme events can have disproportional negative ecological impacts, their ephemeral nature and a ...

Plate tectonics in the microscopy realm: Molecular insights into morphological variability of Peridinium willei (Peridiniales, Dinophyceae)

TAXON, Volume 75, Issue 2, April 2026.
Abstract Freshwater Peridinium willei (Peridiniaceae) is globally distributed, but reports linking its morphologies with DNA sequence data remain scarce. The taxonomy of the species, and its infraspecific taxa, remain ambiguous due to the lack of DNA sequence data for the original and type material.

Using Machine Learning to Uncover Ecological Mechanisms Controlling Abundance of Phytoplankton Size Classes From Large‐Scale Observations

Global Biogeochemical Cycles, Volume 40, Issue 4, April 2026.
Abstract Phytoplankton size classes (PSCs) and Phytoplankton functional types (PFTs) determine many fundamental biogeochemical processes including nutrient uptake, energy transfer through marine food webs, ocean carbon export, and gas exchange with the atmosphere. Discerning the causes of spatio‐temporal variability of PSCs is a scientific priority for

Predicting Karenia brevis Induced Respiratory Irritation at Individual Southwest Florida Beaches Using Cell Abundances Plus Wind Direction and Speed

GeoHealth, Volume 10, Issue 4, April 2026.
Abstract Nearly annually, blooms of the dinoflagellate Karenia brevis form along the southwest Florida coast leading to a variety of negative impacts, including respiratory irritation (RI) in humans. To limit these impacts, NOAA's National Centers for Coastal Ocean Science (NCCOS) developed a RI model to provide beach‐goers with a category‐based ...

The Seasonal Impact of the Island Mass Effect on Coastal Biogeochemistry and Phytoplankton Assemblage: The Case of the Tropical and Volcanic Island of Guadeloupe (French West Indies)

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract The Island Mass Effect (IME) in tropical regions remains understudied, despite its potential to fertilize oligotrophic oceanic gyres and impact on higher trophic levels. Guadeloupe provides an ideal case study of IME due to its diverse nutrient sources, dual exposure to the Caribbean Sea on the western coast and Atlantic Ocean on the eastern ...

Diversity and biogeography of dinoflagellates in the Kuroshio region revealed by 18S rRNA metabarcoding

Frontiers in Marine Science
Dinoflagellate is one of the most diverse and pervasive protists and a fundamental player in the marine food web dynamics and biogeochemical cycles. While possessing different nutritional strategies from purely autotrophy or heterotrophy to mixotrophy ...
