History or current selection? A molecular analysis of 'area effects' in the land snail Cepaea nemoralis.
We have used molecular variation in microsatellite and mitochondrial DNA to throw light on the origins of enigmatic geographical patterns, known as 'area effects', in the shell polymorphisms of the land snail Cepaea nemoralis. Our aim was to assess the relative importance of recent selection and historical events in the formation of these patterns. On the Marlborough Downs in Wiltshire, England...
متن کاملThe inheritance of some characters in Cepaea hortensis and Cepaea nemoralis (Gastropoda).
N recent years the remarkable polymorphism of snails of the genus Cepaea IHeld has continued to attract considerable attention. The variation from place to place in the proportions of the different phenotypes has proved to be useful material for the study of evolution in natural populations (CAIN and SHEPPARD 1950, 1954; CLARKE 1960; CLARKE and MURRAY 1962; LAMOTTE 1951, 1959; SCHNETTER 195 1 ;...
متن کاملCandidate genes for shell colour polymorphism in Cepaea nemoralis
The characteristic ground colour and banding patterns on shells of the land snail Cepaea nemoralis form a classic study system for genetics and adaptation as it varies widely between individuals. We use RNAseq analysis to identify candidate genes underlying this polymorphism. We sequenced cDNA from the foot and the mantle (the shell-producing tissue) of four individuals of two phenotypes and pr...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
New Data on the Genetics of Polymorphism in the Snail Cepaea Nemoralis L.
A REVIEW of the remarkable polymorphism in the European land snail Cepaea nemoralis L. and of the various interpretations based on it has been given in a previous issue of this journal (CAIN and SHEPPARD 1954). Since the adaptive and evolutionary significance of the polymorphism is the subject of active research, a considerably better knowledge of its genetics is desirable. Subsequently, LAMOTT...
