Abstract This paper reviews the literature on the behaviour of ciliated protozoa, describes the locomotion of five species and examines studies of its causation, development, function and evolution.Expand
Rhythmic spontaneous depolarizations determine a slow-and-fast rhythm in walking of the marine hypotrich Euplotes vannus
Summary In the marine hypotrich Euplotes vannus, the coupling of behavioural elements to shifts in the freely fluctuating membrane potential was investigated by use of a computerized locomotion trackExpand
The cyst of Oxytricha bifaria (Ciliata hypotrichida). III: Cytochemical investigation
Analyse cytochimique au niveau ultrastructural des kystes d'Oxytricha bifaria. Mise en evidence de proteines, de polyosides et de chitine
Motor and predatory behavior of Litonotus lamella (Protozoa, Ciliata)
The ethogram of Litonotus lamella is described and discussed. Individuals of the species creep on the substrate at a velocity of 189 ± 40 μm/s, moving toward the right along geometrically perfect a...
Orthokinetic and klinokinetic reactions in the behaviour of Litonotus lamella predating on Euplotes crassus
Summary The behaviour leading the predator (Litonotus lamella) to gather in the areas where the prey (Euplotes crassus) is perceived as abundant has been investigated. The accumulation kinetics wereExpand
Mating-type-specific soluble factors (gamones) in cell interaction of conjugation in the ciliate Oxytricha bifaria
Sexual reproduction in Ciliates occurs through pair formation (conjugation) between cells of complementary mating types. In many species, after complementary cells are brought together, a waitingExpand
Behavioural modifications imposed to the ciliate protist Euplotes crassus by caulerpenyne: the major toxic terpenoid of the green seaweed, Caulerpa taxifolia
Summary Caulerpenyne is the most abundant, toxic terpenoid produced by Caulerpa taxifolia , one of the few toxigenic, green seaweed endemic in the tropics. Owing to the bewildering high concentrationExpand
The interface between air and water: a perturbation source eliciting adaptive behaviour in ciliates.
Interference with the water-air interface, both direct (by contact with a flat, rigid surface) and indirect (by inducing a meniscus) caused the ciliated protozoa we investigated to actively collectExpand
The ethograms of Uronychia transfuga and Uronychia setigera (ciliata, hypotrichida): a comparative approach for new insights into the behaviour of protozoa
Summary The behavioural biology of Uronychia transfuga and Uronychia setigera was studied and their complete ethograms (namely the catalogues of both the qualitative elements and the relativeExpand
The Effects of Cooling Conditions on the Behavior of Oxytricha bifaria (Ciliophora Hypotrichida)
The new analytic approach to the behavior of ciliates represented by the ethogram was used to study the locomotion of Oxytricha bifaria at different temperatures, isotropically applied according to aExpand
