easy prey

(National Science Foundation) Running for more than 1,000 kilometers along picturesque coastline, California's Highway 1 is easy prey for many of the natural hazards plaguing the region, including landslides.

Seabird colonies on islands are highly vulnerable to introduced rats, which find the ground-nesting birds to be easy prey.

But the ecological impacts of rats on islands extend far beyond seabird nesting colonies, according to a new study.
