The Texas State Bison Herd is also a useful example of the deleterious effects of extreme population bottlenecking, with an average natality rate of 0.376 offspring per female and a 1st-year mortality rate of 52.6% from 1997 to 2002, compared to an average natality rate of 0.560 offspring per female and a 1st-year mortality rate of 4.2% for the ...
