| Résumé anglais |
Ecological phenomena are characterised by their interdependance that can be observed through the ecosystems ruled themselves by energical flux. But these flux are not always constant, neither at the human life scale, nor at the geological eras'one. Their variations lead to the break of balances, elaborated during periods of relation stability, which infer the alternance of stages than can be seen in all parts of analysis, for example in morphogenesis and pedogenesis relations. Human being can have a great impact on the breaks of balance. Source : Éditeur (via Persée) |
