species extinction and conservation genetics
Causes of extinction
habitat destruction
overkill
pollution
climate change
invasive species
Genetic diversity
neutral genetic diversity
traditionally used as a measure of population health
no clear correlation with species extinction risk
weak predictor for adaptive potential and population viability
criticism of neutral genetic diversity
No strong evidence to long-term population survival
IUCN red list doesn't correlate with genome-wide diversity
relationship between neutral genetic diversity, functional genetic diversity, and population viability is complex
functional genetic diversity
directly impacts fitness
genomic variants are more relevant to conservation efforts than neutral genetic diversity
high genetic diversity
assumed to increase fitness and survival
used in genetic rescue
low genetic diversity
often seen as a sign of inbreeding depression and genetic drift
reduced lifespan, health, and fitness
inbreeding depression
mating between related individuals exposes deleterious recessive alleles
results in decreased fitness and can contribute to extinction
outbreeding
introduction of genetic diversity masks recessive deleterious alleles
can increase population fitness
effective conservation strategies
mitigating habitat destruction, overkill, and climate change
preserve adaptive genetic variations
address both genetic and ecological causes
