Anoxic anoxia in strophocheilus (pulmonata mollusca)
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1971Abstract 1. 1. The snail Strophocheilus oblongus musculus can resist totally anaerobic conditions for up to 48 hr. 2. 2. During anoxia the level of blood glucose falls from 20.1 mg/100 ml to 8.4 mg/100 at 15 hr; afterwards it increases continuously, reaching 94.1 mg/100 ml at 25 hr. 3. 3.

Ionic balance in the blood of pulmonata
Comparative Biochemistry and Physiology, 1968Abstract 1. 1. Sodium, potassium, calcium and magnesium have been determined in the blood of hydrated specimens of Helix pomatia, Cepaea nemoralis, C. hortensis, Arianta arbustorum, Archachatina marginata, Arion ater ater, A. ater rufus, Lymnaea stagnalis and Planorbarius corneus, and the average values, together with others already published ...

The haemocyanin of Lymnaea stagnalis L. (Gastropoda: Pulmonata)
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1975Abstract 1. 1. The haemolymph of Lymnaea stagnalis (L.) was shown to contain a typical gastropod haemocyanin by virtue of its absorption spectrum, copper content, and electromicroscopic appearance. 2. 2. The native haemocyanin molecule ( s 20, w 0 = 99·7S) underwent partial dissociation into one-half molecules ( s 20, w 0 = 63·0S ...

The genus Vallonia in Nepal: (Gastropoda: Pulmonata: Valloniidae)
Archiv für Molluskenkunde, 2009Only two Nepalese records of the holarctic land snail genus Vallonia have hitherto been published. Here five species of Vallonia are recorded from Nepal: V. ladacensis (nevill 1878), V. tenuilabris (A. braUn 1843), V. costohimala n. sp., V. himalaevis n. sp., and V. kathrinae n. sp.

Phylogeny of the land snail family Clausiliidae (Gastropoda: Pulmonata)
Molecular Phylogenetics and Evolution, 2013Clausiliidae is one of the most speciose and best-studied families of land snails. The family contributes to land snail diversity on a global scale, with three main centres of diversity: (1) western Eurasia (six subfamilies recognized), (2) East Asia (two subfamilies recognized) and (3) the neotropics (one subfamily recognized i.e. Neniinae). Despite a

Aspects of ionic regulation in certain terrestrial pulmonata
Comparative Biochemistry and Physiology, 1966Abstract 1. 1. On crawling over a wet surface, dehydrated specimens of Otala lactea and Helix aperta absorb water into the blood until, within 2–3 hr, the concentrations of sodium, potassium, calcium, magnesium and total solutes have fallen to approximately constant levels which are similar in the two species. 2. 2. Though the two species are
