Are populations genetically healthy?Measure genetic diversity• Compare past and present levelsEstimate population size• See whether population is changingPlan breeding programs to avoid inbreeding or species mixingRuokonen et al. 2007,Conservation Genetics
Genetic rescueExample• A population of Swedish adderssuffered from inbreedingdepression• Stillborn offspring, lowgenetic variability• Researchers released 20 malesfrom another population →breeding succes and populationsize increased• Correspond to increase ingenetic diversityMadsen et al. 1999, NatureAdder in the spring mood.Photo: Marjatta Sihvonen
