Abstract excerpt

Predicting the genetic consequences of population decline is a major problem in conservation genomics. Time lags following demographic bottlenecks can delay genomic erosion and make it difficult to determine a population's current and future risk, especially when prebottleneck genomic baselines are unavailable. Black abalone (Haliotis cracherodii) suffered a severe disease bottleneck in the 1980s, resulting in an...
