... proteins in the adhesive mucus. The present study identifies similar proteins from the glue of the slug Arion subfuscus and the land snail Helix aspersa . To investigate the role played by these proteins in adhesion,the proteins were isolated from the adhesive mucus of different molluscs and added...

...Tomasz Antkowiak; Ronald Chase SUMMARY Because oviposition in the land snail Helix aspersa is a metabolically expensive process coupled to a high fixed cost, one expects oviposition to occur only when the clutch size surpasses a minimum value at which the reproductive benefit exceeds the cost. We...

...Basile Michaelidis; Nikolaos S. Loumbourdis; Elizabeth Kapaki SUMMARY The aim of the present study was to determine the levels of monoamines,GABA and adenosine in the brain, heart and haemolymph of the land snail Helix lucorum and in the brain, heart and blood of lizard Agama stellio stellio during...

...Basile Michaelidis; Evangelia Rofalikou; Manfred K. Grieshaber ABSTRACT The effects of hypercapnia, together with low and high levels of extracellular Ca 2+ , on heart activity and intracellular pH were examined in isolated perfused hearts from the land snail Helix lucorum . In addition...

...Basile Michaelidis; Artemis Pallidou; Paraskevi Vakouftsi ABSTRACT The aims of the present study were to describe a possible correlation between the regulation of the key glycolytic enzyme pyruvate kinase and the acid–base status in the haemolymph and in several other tissues of land snails during...

...Bernard B. Rees; Steven C. Hand ABSTRACT Within 4 days following entry into estivation, heat dissipation and oxygen consumption by the land snail Oreohelix spp. decreased by 83% compared to standard non-estivating rates. During both non-estivating and estivating conditions, the quantity of heat...
