Speciation of termite gut protists: the role of bacterial symbionts [PDF]

open access: yes, 2010
At least 12 termite gut protists have been named because of their bacterial symbionts. Dozens more species are diagnosed by epi- and endosymbionts and more still have regular bacterial associations referred to in their species description.

Tracking Cell Movement in Two‐Dimensional, Fragmented Microcosms Reveals Dispersal Syndromes and Strategies in Tetrahymena thermophila

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
Dispersal strategies of the ciliate Tetrahymena thermophila were investigated using ‘two‐dimensional’ artificial landscapes, allowing for camera tracking of individual cell trajectories during all steps of the dispersal process. Strains showed distinct strategies at emigration, either increasing or decreasing movement traits (swimming speed and ...

Evolution: functional evolution of nuclear structure. [PDF]

open access: yes, 2011
The evolution of the nucleus, the defining feature of eukaryotic cells, was long shrouded in speculation and mystery. There is now strong evidence that nuclear pore complexes (NPCs) and nuclear membranes coevolved with the endomembrane system, and that ...

Rain, Bark, and Residual Variability in Stemflow From Three Dominant Tree Species of a Southern Great Lakes Forest

open access: yesHydrological Processes, Volume 40, Issue 2, February 2026.
Terrestrial LiDAR and hydrology calibration were used to derive each tree's stemflow drainage area, normalising rainfall‐stemflow relations by contributing surface. The results show that Fagus grandifolia (beech) maintains a stronger, steeper hydrological response to rainfall (exhibited by a higher normalised yield) than Acer saccharum (maple) and ...

Comparative single-cell genomics of two uncultivated Naegleria species harboring Legionella cobionts

open access: yesmSphere
Amoeboflagellates of the genus Naegleria are free-living protists ubiquitously found in soil and freshwater habitats worldwide. They include the “brain-eating amoeba” Naegleria fowleri, an opportunistic pathogen that causes primary amoebic ...

Biofilm Analysis by Confocal Microscopy—Basics and Practical Aspects

open access: yesMicroscopy Research and Technique, Volume 89, Issue 2, Page 183-206, February 2026.
Development and detachment of an interfacial microbial community. The resulting biofilms and bio‐aggregates are three‐dimensional communities susceptible to examination by confocal laser scanning microscopy. ABSTRACT This review is intended as a guideline for beginners in confocal laser scanning microscopy.

Dual‐scale drivers of soil biodiversity in agroecosystems: Field management outweighs landscape effects, but both matter

open access: yesJournal of Applied Ecology, Volume 63, Issue 2, February 2026.
These findings highlight the need for conservation strategies that integrate both field‐scale and landscape‐scale planning. The promotion of diverse land use types might offer a practical pathway to maximize the effectiveness of soil biodiversity conservation within an intensively managed agricultural matrix.

An Explicit Test of Kill the Winner: Protistan Grazing and Phage Lysis Differentially Impact Fast‐Growing Bacterial Taxa in the Coastal Antarctic

open access: yesEnvironmental Microbiology, Volume 28, Issue 2, February 2026.
We evaluated whether predators ‘kill the winner’ wherein protists and phages preferentially impact the most abundant members of bacterial assemblages over an austral summer with weekly dilution experiments. Seawater from 10 m was divided into two serial dilutions with either 0.2 μm (to evaluate protist grazing) or 30 kDa (to evaluate protist grazing ...
