The article presents a study which evaluated the role of inbreeding in extinction using realistic population viability analyses of threatened species, with and without inbreeding depression. The major variable which explains differences among species was initial population growth rate while the impact of inbreeding was least in species having negative growth rates. The results show that the prospects for survival of threatened species will usually be seriously overestimated if genetic factors are disregarded.

    Pedigree analysis has clear benefits for the genetic management of threatened populations through the evaluation of inbreeding, population structure and genetic diversity. The use of pedigrees is usually restricted to captive populations and few examples exist of their exclusive use in managing...

    The endangered Mexican fishing bat, Myotis vivesi, appears to have suffered widespread extinction and population decline on islands throughout the Gulf of California, largely due to predation by introduced cats and rats. To restore populations of fishing bats and other native species,...
