The paper analyzes gene loss in freshwater sticklebacks using a pangenome approach, finding that demographic factors and selection influence gene presence/absence variation.

The paper tests the drift-barrier hypothesis by analyzing mutation rates in nine-spined stickleback populations, finding a negative correlation between mutation rates and effective population size.

The paper examines recombination rates and linked selection efficiency in small and large stickleback populations, finding higher recombination in a small freshwater population and a polygenic basis for recombination rates.

The paper estimates de novo mutation rates in three-spined sticklebacks using family trios and finds a mutation rate of 5.05 x 10^-9/bp/gen with a positive correlation between mutation rate and recombination rate.

The paper estimates de novo mutation rates in two marine populations of nine-spined sticklebacks using family pedigrees and whole genome sequencing, finding rates lower than commonly used substitution rates.
