Polymorphism in Pleistocene Land Snails

Science, 1966
Under suitable conditions the colors and patterns of the shells of land snails may be preserved for thousands of years. In a late Pleistocene population of Limicolaria martensiana all the major color forms that occur in modern living snails may be distinguished, and the basic polymorphism is at least 8,000 to 10,000

The Land Snail Fauna

1975
The Indo-Pacific region has been divided into land snail faunal zones by a number of authors (Fischer, 1880–87, 1950; Cook, 1895; Solem, 1959). Solem (1959) has presented the most recent account giving an illustrated synthesis of the earlier schemes (figs.

Possible dispersal of land snails by birds

Ornithological Science, 2008
Abstract Birds are potential dispersal agents of land snails by internal passage through the alimentary canals, such as plant seeds. Thus, we investigated whether snails are found in bird feces and checked damage to them in the oceanic Bonin Islands.

Biogeography of Galápagos Land Snails

1991
Land snails are among the earliest scientific collections recorded for the Galapagos. Although land snails have not always been the primary interest of collectors visiting the islands, material—mostly empty shells—made its way to private collections and museums in Europe and the United States, where it was described by specialists.

Behavioural Rhythms of Land Snails in the Field

Biological Rhythm Research, 2004
Circadian and circannual behavioural rhythms of Helix are described in the field. Laboratory studies demonstrate the existence of an endogenous component for these rhythms. The effects of the environmental factors on the snail activities are multiple: light/dark and cold/warm cycles synchronise the behavioural rhythms; a masking effect is observed when

Electrical Trapping Device for Land Snails

Journal of Economic Entomology, 1965
In conjunction with projected studies on the biology and behavior of the brown garden snail, Helix aspersa (Muller), it appeared desirable to develop a trapping device which would retain individual snails attracted to a specific location. The emergent problem was to design a unit which would capture snails of varying shell sizes and subsequently would ...

Land snails: distribution and notes on ecology

1984
The study of land snails of Sri Lanka has not had any long sustained interest since the monumental contributions of Blanford & Godwin-Austin (1908) and Gude (1914,1921). As a result, there is little information on their systematics, ecology and distribution in the different climatic zones of the Island.
