Species live in complex systems of interactions. Both theoretical and empirical examples have shown that changes in the population size of just one single species can have dramatic effects on the whole ecosystem. The reduction of a single species population can yet have as far reaching consequences as to cause extinctions of other species within the community. Is there a treshold level above which the population of a certain species needs to maintained in order to avoid such devastating consequences?

This question is the reasoning behind my master thesis in the "Ecology and the Environment" program.
