Calcium regulation in the freshwater mollusc, Limnaea stagnalis (L.) (Gastropoda: Pulmonata). I. The effect of internal and external calcium concentration.

Potassium Movements in a Central Nervous Ganglion of Limnaea Stagnalis (l.) (gastropoda :pulmonata)

Effect of acute exposure to low environmental calcium on respiration and locomotion in Lymnaea stagnalis (L.).

Environmental calcium is a major factor affecting the distribution of freshwater gastropods. Whilst the effects on growth and morphology are fairly well understood, little is known about how calcium availability affects other aspects of gastropod biology. Lymnaea stagnalis (L.) is considered a calciphile and exhibits reduced growth and survival in environments containing less than 20 mg l(-1) C...

Electrophysiology of the giant nerve cell bodies of Limnaea stagnalis (L.) (Gastropoda: Pulmonata).

The giant somata (cell bodies) of neurones in the central ganglia of Limnaea stagnalis (L.) have become material for several lines of neurobiological research. For example, the electrical responses of these cells have been employed in pharmacological studies (Vulfius & Zeimal, 1967; Vulfius et al. 1967; Zeimal & Vulfius, 1967; Jurchenko, Vulfius & Zeimal, 1973; Moreton & Gardner, 1974). Also, t...

Contribution of disulfide bonds and calcium to Molluscan hemocyanin stability.

Disulfide bonds and calcium ions contribute significantly to the stability of the hemocyanin from the mollusc Rapana thomasiana grosse (gastropod). An extremely powerful protective effect of Ca2+ at a concentration of 100 mM (100% protection) against the destructive effect of reductants like dithiothreitol was observed. This is important for the practical application of molluscan hemocyanins in...
