Protistan Plankton Responses to Variable Light and Upwelling in the Peruvian Humboldt Current System: Insights Into Community Dynamics Under Environmental Change

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
Our study reveals (based on experiments) the shifts in protistan plankton communities, serving as energy and organic matter source for higher trophic levels if the Humboldt Current System is affected by climate change as predicted by current models. This may have profound effects on fisheries in the Humboldt Current System.

Characterising Soil Eukaryotic Diversity From NEON Metagenomics Datasets

open access: yesMolecular Ecology Resources, Volume 26, Issue 1, January 2026.
ABSTRACT Belowground eukaryotic diversity serves a vital role in soil ecosystem functioning, yet the composition, structure, and macroecology of these communities are significantly under‐characterized. The National Ecological Observatory Network (NEON) provides publicly available datasets from long‐term surveillance of numerous taxa and ecosystem ...

A holistic perspective on planktonic communities across the Northwestern Mediterranean Sea

open access: yesFrontiers in Marine Science
The Northwestern Mediterranean Sea is undergoing rapid environmental changes driven by climate variability and intense anthropogenic pressure. To monitor and understand the long-term impacts on marine ecosystems, the Mediterranean Ocean Observing System ...

Integrating Horizontal Gene Transfer and Common Descent to Depict Evolution and Contrast It with ‘‘Common Design [PDF]

open access: yes, 2010
Horizontal gene transfer (HGT) and common descent interact in space and time. Because events of HGT co-occur with phylogenetic evolution, it is difficult to depict evolutionary patterns graphically. Tree-like representations of life’s diversification are

Integrative taxonomy of new xenophyophores (Rhizaria, Foraminifera) from the abyssal northwest Pacific

open access: yesEuropean Journal of Taxonomy
Xenophyophores dominate the abyssal megafauna across many areas of the Pacific Ocean. These giant agglutinated foraminifera have been studied mainly in the tropics, including within the Clarion-Clipperton Zone (CCZ), from where the majority of recently ...

Illuminating protist diversity in pitcher plants and bromeliad tanks.

open access: yesPLoS ONE, 2022
Many species of plants have evolved structures called phytotelmata that store water and trap detritus and prey. These structures house diverse communities of organisms, the inquiline microbiome, that aids breakdown of litter and prey.

Discrimination, Crypticity, and Incipient Taxa in Entamoeba [PDF]

open access: yes, 2012
Persistent difficulties in resolving clear lineages in diverging populations of prokaryotes or unicellular eukaryotes (protistan polyphyletic groups) are challenging the classical species concept.

The Romantic Discovery of Radiolaria in the Ocean

open access: yesJournal of Eukaryotic Microbiology, Volume 73, Issue 1, January/February 2026.
ABSTRACT Radiolaria are unicellular marine organisms (protists) that have been drifting in oceanic plankton for hundreds of millions of years. These mineral architects can build extraordinarily complex skeletons, which fascinated and puzzled naturalists observing water samples through rudimentary microscopes.

A new 'saccamminid' genus (Rhizaria: Foraminifera), from 4400 m water depth in the Nazare Canyon (NE Atlantic) [PDF]

open access: yes, 2011
We describe Bithekammina occulta, a new monothalamous agglutinated foraminiferan ('saccamminid') collected in multicore samples at 4400 m on the terrace of the lower Nazare Canyon on the Portuguese margin.
