An invasive fish and the time-lagged spread of its parasite across the Hawaiian archipelago.
Efforts to limit the impact of invasive species are frustrated by the cryptogenic status of a large proportion of those species. Half a century ago, the state of Hawai'i introduced the Bluestripe Snapper, Lutjanus kasmira, to O'ahu for fisheries enhancement. Today, this species shares an i...

Efforts to limit the impact of invasive species are frustrated by the cryptogenic status of a large proportion of those species.
