Environmental DNA for invasive rat surveillance and biosecurity on islands

open access: yesConservation Science and Practice, EarlyView.
We collected aquatic eDNA samples from beach and lake sites on three atoll islands with different invasion statuses before and after a rat eradication operation. Two dozen eDNA samples can confirm with ≥95% probability the presence of invasive rats prior to any management intervention. However, following the eradication operation, neither targeted eDNA

Integrating ecological feedbacks across scales and levels of organization

open access: yesEcography, EarlyView.
In ecosystems, species interact in various ways with other species, and with their local environment. In addition, ecosystems are coupled in space by diverse types of flows. From these links connecting different ecological entities can emerge circular pathways of indirect effects: feedback loops.
