Behavioral modifications of Liriope tetraphylla (Chamisso and Eysenhardt) (Cnidaria, Hydrozoa, Trachymedusae) induced by hyposmotic conditions

Journal of Experimental Marine Biology and Ecology, 1996
Abstract The osmoregulatory capability and swimming behavior of Liriope tetraphylla (Chamisso and Eysenhardt) were analyzed under hyposmotic conditions. These hydromedusae are shown to be osmoconforming animals that are not able to maintain constant osmotic and ionic concentrations of their body fluids when exposed to anisosmotic media.

Pharmacology of the radial neuromuscular system of Liriope tetraphylla (Hydrozoa, Trachymedusae)

Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1988
Abstract 1. 1. In an attempt to analyse the cholinergic pre-synaptic modulatory hypothesis (Scemes and Mendes, 1986), the effects of magnesium and calcium ions and of cholinergic agonists and antagonists on the behavior of Liriope tetraphylla were studied. 2. 2.
