Plant Evolution in Extreme Environments,ally and spatially. In extreme environments a single physical factor is usually dominating and other factors subsidiary. This makes it easy to understand what is going on, and to define the intensity of the factor. Extreme habitats are so distinctive that it is also easy to see where they begin and

Polymorphism in a Polynesian Land Snail ,on (1932), who considered their polymorphic varieties of shell colour and pattern to represent ‘indifferent characters’ unaffected by natural selection. To account for the variations found in the genus, Crampton invoked the pressures of recurrent mutation and migration. More recently they have been

Evolutionary Oscillations in , great selective forces are normally operating to maintain or to adjust the adaptations of organisms in natural conditions ... That consideration forces us completely to readjust our thoughts on evolution and to recognize that a population may adapt itself very rapidly to changed conditions.’ Indeed

Melanism in the Two-spot Ladybird, ,, in Great Britain, much of the insect’s range, including continental Europe (Lusis 1961), Britain (Hawkes 1920, 1927; Creed 1966, 1969) and Canada (Smith 1958). Surveys sufficiently detailed to permit conclusions to be drawn about the causes of local, and hence of general, variation have been undertaken by Lusis in L

The Distribution of Melanism in the Pale Brindled Beauty Moth, ,, in Great Britain, in their epidermal scales. For over a century this has received much attention from entomologists and more recently geneticists. In Britain early attempts to account for the occurrence of melanism in many different ecological situations stressed the importance of environmental factors acting direct

Recessive Melanism in the Moth , L. in Industrial and Non-Industrial Areas,everal unusual features. First, melanic polymorphisms were maintained among imagines in several populations which appeared to be isolated from one another. They exist both in regions influenced by industrial pollution and in others which are essentially unpolluted.
