Part J: ZB VII—Zonobiome of Steppes and Cold Deserts or of Arid Temperate ClimateTibet and Pamir) with long cold winter months. In the southern hemisphere ZB VII is only represented in South America with only a relatively small area in the Argentine pampa and the Patagonian semi-desert.

Part K: ZB VIII—Zonobiome of the Taiga or of the Cold Temperate Boreal Climatef ZB VIII against the Arctic is where about only 30 days with daily means above 10 °C and a cold season of 8 months are typical for the climate. The vegetation are often oceanic birch forests or continental coniferous forests (taiga), but often water-saturated mires and bogs may prevail.

Part F: ZB III: Zonobiome of Hot Deserts or Subtropical Arid Climateith the innertropical convergence zone. According to rainy season various desert types develop, and which are according to substrate conditions again modified. The different floral kingdoms are the basis for the flora, where xerophytes dominate, which exhibit evolved convergent adaptions to drought conditions.

Part L: ZB IX—Zonobiom of the Tundra, the Arctic Climatey from S to N. The largest forestless tundra area occupies a huge area of three million square kilometres in N Siberia, north of the Arctic timberline. In the South, s of the Antarctic timberline, tundra occurs only in small areas and on some islands. Antarctica itself is covered by a huge ice desert.

Preliminary Remarksa whole is connected with open cycles and energy flow—i.e. a build-up of substances with binding of solar energy as well as a decomposition with the release of the bound energy mostly in the form of heat. Basic understanding needs biological data on biodiversity (systematics and taxonomy) as well as

Part B: Ecological Basis (Synecology)tions is almost never correct. These are only of indirect importance by altering the competitiveness of species. Only at the absolute limits of distribution in the arid and cold desert, at the edge of the salt desert, i.e. where the individual plants are isolated, are the site factors (usually a cer
