Persistence of different sized populations: An empirical assessment of rapid extinctions in bighorn sheep
Berger J. 1990. Persistence of different sized populations: An empirical assessment of rapid extinctions in bighorn sheep. Conservation Biology. 4(1):91-98
Theory and simulation models suggest that small populations are more susceptible to extinction than large populations, yet assessment of this idea has been hampered by lack of an empirical base. This paper addresses how long different sized populations persist considering food shortages, severe weather, predation, or interspecific competition.
