Euplotes

Another test organism suggested for the estimation of wastewater entering the treatment plant is Euplotes patella [103]. 

These contrasting observations may perhaps be reconciled by admitting that warm-water marine organisms have adapted to the Antarctic. This has received circumstantial evidence from the finding of the same terpenoids in ciliate protists, Euplotes spp., fi m the Red Sea and the Antarctic. These...

Two diterpenoids, focardin (Structure 7.171) and an epoxide derivative (Structure 7.172), are produced by the marine ciliate Euplotes focardii, collected from Ross Sea coastal waters.195 Focardin is autotoxic and inhibits other ciliates, including one sympatric species, suggesting they are present... 

Scarce resources, such as food or space, in some marine environments can lead to production of compounds for the offensive role of reducing competition. Focardin (Structure 7.171) and its 11,12-epoxide (Structure 7.172), produced by the Antarctic ciliate Euplotes focardii, are autotoxic and cytotoxic toward a sympatric ciliate and a selection of temperate and tropical predatory ciliates.195...

In the initial mixed zooplankton experiments, Long et al. (submitted) found that crustacean mesozooplankton, dominated by adult copepods A. tonsa and P. pelagicus, significantly suppressed colony formation. In other experiments, Long et al. (submitted) found that infochemical cues alone from the mesozooplankton A. tonsa alone suppressed colony formation. Long et al. (submitted) also observed that the colony suppression effect of A. tonsa was density dependent. In experiments with the microzooplankton Euplotes spp., Long et al. (submitted) reported that info-chemical cues from this ciliate enhanced P. globosa colony formation.
