... number of young released necessary to obtain a new successful population (with a probability of extinction of P < 0Á001 during 50 years) varies from 54 per year over 2 years to four per year over 23 years (Fig. 4), with num- ber of young per year showing a significant negative expo- nential relationship with number of years (r = À0Á788, P < 0Á001). Consequently, as we reduce the number of young released each year, the number of years necessary to obtain a successful population increases exponentially. Analysing only the cases between 2 and 13 ...
