Combining transient dynamics and logistic‐asymptotic growth to study the recovery of two seabird populations after rat eradication

open access: yesPopulation Ecology, EarlyView.
This study examines the demographic dynamics of two seabird populations on Tromelin Island, 15 years after the eradication of brown rats. The results indicate that these populations are in good health and are expected to continue growing until breeding sites are saturated in about a century.
