Arrest of cytoplasmic streaming induces algal proliferation in green paramecia. [PDF]
PLoS ONE, 2007 A green ciliate Paramecium bursaria, bearing several hundreds of endosymbiotic algae, demonstrates rotational microtubule-based cytoplasmic streaming, in which cytoplasmic granules and endosymbiotic algae flow in a constant direction.

Ecological interactions in glacier environments: a review of studies on a model Alpine glacier
Biological Reviews, Volume 100, Issue 1, Page 227-244, February 2025.ABSTRACT Glaciers host a variety of cold‐adapted taxa, many of which have not yet been described. Interactions among glacier organisms are even less clear. Understanding ecological interactions is crucial to unravelling the functioning of glacier ecosystems, particularly in light of current glacier retreat.

The Paramecium germline genome provides a niche for intragenic parasitic DNA: evolutionary dynamics of internal eliminated sequences. [PDF]
PLoS Genetics, 2012 Insertions of parasitic DNA within coding sequences are usually deleterious and are generally counter-selected during evolution. Thanks to nuclear dimorphism, ciliates provide unique models to study the fate of such insertions.

Wall Drag on Free-Moving Ciliated Micro-Organisms [PDF]
, 1973 It is generally assumed that wall drag on free-moving, self-propelled or passively moving micro-organisms is not significant under normal observation conditions. Yet the point at which such drag becomes significant has not been determined quantitatively.

Fruit Flies Provide New Insights in Low-Radiation Background Biology at the INFN Underground Gran Sasso National Laboratory (LNGS) [PDF]
, 2018 Deep underground laboratories (DULs) were originally created to host particle, astroparticle or nuclear physics experiments requiring a low-background environment with vastly reduced levels of cosmic-ray particle interference. More recently, the range of

Paramecium swimming in capillary tube [PDF]
arXiv, 2010 Swimming organisms in their natural habitat navigate through a wide array of geometries and chemical environments. Interaction with the boundaries is ubiquitous and can significantly modify the swimming characteristics of the organism as observed under ideal conditions.

Warming During Different Life Stages has Distinct Impacts on Host Resistance Ecology and Evolution
Ecology Letters, Volume 28, Issue 2, February 2025.Investigating whether animals can adapt to infection with rising temperatures is important for forecasting their persistence under climate change. Using a nematode host–bacterial pathogen system, our study shows that prolonged warming selects for resistance. The evolutionary dynamics of resistance depended on the balance among pathogen virulence, costs
