Exergetic Model of Secondary Successions for Plant Communities in Arid Chaco (Argentina)

International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013
Ecosystems are open systems where energy fluxes produce modifications over plant communities. According to the state and transition model, plant formations are defined by changes in natural conditions and disturbs. Based on these changes, it is possible to define vectors that show the tendencies of the communities towards other states.
