Zonobiome of the Tundra Climatemafrost extends far down into the ground (Fig. 113). The depth to which the ground freezes in winter has no influence upon the vegetation, since the growth of plants depends only on the thickness of the upper soil layer thawing out in summer.

Introduction: The Classification of Ecological Systems soil, vegetation, and animal life should not, therefore, be considered simply as isolated branches of science. It is impossible to separate the phenomena associated with life from environmental factors, and the task of the ecologist is to understand these interconnections. The biosphere is a vast e

Zonobiome of the Equatorial Diurnal Climate With Evergreen Tropical Rain Forestthere large areas in which the monthly rainfall does not fall below 100 mm, whereas in the Amazon basin there is merely a small area on the Rio Negro. A short dry season invariably occurs in India and is observable in most years in the Congo basin (Fig. 20).

The climate diagrams of the various subzonobiomes are very similar in shape except with regard to summer drought, which varies in extent. The climate will therefore be termed mediterranean in type. The vegetation consists mainly o

Zonobiome of the Arid-Temperate Climateca, it occupies the entire Midwest, from southern Canada to the Gulf of Mexico. The degree of aridity varies considerably, and four subzonobiomes can be distinguished: (1) a semiarid subzonobiome having a short period of drought, with steppe and prairie vegetation (Fig. 87, Chkalov); (2) a very arid

Zonobiome of the Cold-Temperate Boreal Climates become too short and winters too long. This is recognizable in the climate diagram as the point where the duration of the period with a daily average temperature of more than 10°C drops below 120 days and the cold season lasts longer than 6 months (Fig. 112). The northern boundary between the real

Zonobiome of the Tundra Climatemean temperature above 0°C, and sometimes as few as 55. The low summer temperatures are partially due to the large amount of heat required to melt the snow and thaw out the ground. Winters are rather mild in the oceanic regions but extremely cold in the continental regions (Fig. 118). However, the c
