Insights into the Cyst Organisation and Selected Morpho-Physiological Aspects of Encystment in Thulinius ruffoi
<p>This dataset is related with studies on morpho-physiological aspects of encystment in Thulinius ruffoi (Parachela, Isohypsibioidea: Doryphoribiidae). Data gathered to elucidate the adaptations of these microinvertebrates to environmental changes. Encystment is an adaptive response in tardigrades triggered by environmental cues and potentially by internal factors. The dataset provides insights into cellular organization, morphology, and anatomy during cyst formation in selected tardigrade species. This dataset is supplemented by two others available at <a target="_new" rel="noopener">10.5281/zenodo.10008352</a> and <a target="_new" rel="noopener">10.5281/zenodo.11213808</a>.</p>

Fig. 1 in Evidence of Stress Recovery in Free-Living Ciliate Colpoda cucullus: The Repair Capability of Resting Cysts to Damage Caused by Gamma Irradiation
Fig. 1. Excystment assay of Colpoda wet cysts (A) and dry cysts (B). 'Non-irradiated' indicates non-irradiated cysts; 'irradiated' indicates cysts irradiated at 4000 Gy, and 'irradiated-incubated' indicates cysts irradiated at 4000 Gy and incubated for 12 hours before the induction of excystment. Time indicates the number of hours after the induction of excystment. Columns and attached bars correspond to the means and standard errors, respectively, of six measurements. Asterisks and double asterisks represent significant differences at p <0.05 and p <0.01 (Mann-Whitney U test), respectively.
Fig. 6 in A Study on Resting Cysts of an Oxytrichid Soil Ciliate, Rigidohymena quadrinucleata (Dragesco and Njine, 1971) Berger, 2011 (Ciliophora, Hypotrichia), Including Notes on its Encystation and Excystation Process
Fig. 6. Rigidohymena quadrinucleata, the basic scheme of two excystation modes. The standard mode: The beginning of excystation process is connected with formation of a transparent space between cyst wall and excysting cell. A little later, appears the excystation vacuole. The regenerating specimen breaks the cyst wall and escapes within the single, transparent membrane. The transparent membrane is broken by the excystant and resorbed in the enviroment. The rare mode: The beginning of excystation is associated, similarly, as in the standard mode, with formation of a transparent space and excystation vacuole. The regenerating specimen breaks the transparent membrane first, instead of breaking the whole cyst wall. Finally, the rest of the cyst wall is ruptured by the moving cell and the pressure of the excystation vacuole. The cell leaves the resting cyst. The transparent membrane remains in the empty cyst as a residual body.
