Predicting Species Interactions From Edge Responses: Mongoose Predation On Hawksbill Sea Turtle Nests In Fragmented Beach Habitat

July 29, 2017

Human land use can fragment landscapes, creating new habitat edges. These edges affect how animals use the landscape and how predators interact with their prey.

Edges of beach vegetation in Barbados create an ecological trap for endangered hawksbill sea turtles: while hawksbills prefer to nest near vegetation, introduced mongooses stay in vegetation and prey on nests near the edge.

Based on the interaction between hawksbills and mongooses, we developed a new general method for predicting the location and severity of predation near edges.

Our study highlights an important consequence of landscape fragmentation and provides a new tool for conservation management.
