Abstract The relative importance of extreme and mean climatic conditions in respect to their influence upon the persistence of species. The biological significance of temperature summations. The importance of absolute minima, even when infrequently paralleled, in influencing geographical distribution. Frost severity in relation to the survival of “winter annuals” and of “summer annuals.” Maximum temperatures and their effect upon flower and seed production. The nature of the soil surface and its effect upon air temperatures. The influence of meteorological conditions upon plant life as modified by the biology of the species. The importance of katabatic winds in modifying temperatures affecting plant life. Duration and intensity of sunshine as they effect reproduction; photoperiodism. Precipitation and its role: (1) as a source of raw material; (2) as an erosion agent; (3) in leaching. The significance to plant life of the seasonal incidence and intensity of precipitation. Meteorological factors as influencing soil development and the extent of their modification by the plant covering. Ecological aspects of wind; its direct and indirect effects. The influence of meteorological factors on the conditions of life in relation to the time factor as illustrated by dune soils. Edaphic succession.
