摘要: Savannas are among the most variable of terrestrial ecosystems. They undergo large and frequent changes in production, composition structure they contain some worst examples degradation by man. There are, accordingly, many references to them as “fragile” “brittle” ecosystems, with predictions imminent “collapse”. But these terms have been used loosely, jargon, we need now progress beyond this vague terminology. What, precisely, do mean terms? Is it possible be more precise? More specifically, can achieve an understanding equilibrium behaviour savannas? For deals how change, much change before is irrevocable.
