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
At least four of the bighorn sheep census locations are within Joshua Tree National Monument. Survival of isolated populations of bighorn sheep is correlated with weather records. The study finds that rapid extinctions are not likely to be caused by food shortages or similar factors, but that 50 or fewer bighorns are simply not enough to keep a population going.
