Description:
For the use of ecosystems with savage fauna it is essential to dispose of -instruments which can let one to simulate the effects that natural circumstances or human actions could have on them. Because ecosystems are extremely complicated and because we are not able to experiment "in real life" -behavior are irreversible- it becomes necessary- "to experiment in the laboratory" the effects of the different events that may affect its future life. This "laboratory tests" can be done with the construction of an ecosystem (a model is a formal representation in scale) that later will have to be implanted on a bearing, and will be the object of simulation exercices. A good procedure of the construction of the model and the simulation is what we calle “System Dynamics” (DS).The non existence of previous proofs in the use of ecosystem with savage fauna leads conscious of unconsciously to the disappearance of going down of the species in specific ecosystems. The examples of Kaibab's land, the “Urogallo cantábrico" or of the grouse -are paradigmatic. The purpose of this work is to introduce concisely the model and the conclusions obtained from its use, for the study of the evolution of the rabbit population in a plot of 10 hectares in South Spain. The rabbit (Oryctolagus cuniculus, L.) has been chosen for its enormous value as a prey for upper birds of prey (Imperial eagle, Royal kite, Black kite, Linx and Fox, etc. etc.)
