5 Screech owls eat blind snakes. But sometimes, a screech owl will bring a live, blind snake back to its nest. There the snake eats mites, larvae, and other pests that infest the nest.

10 Before it was banned in the United States in 1972, the pesticide DDT was used to treat wetlands where mosquitos breed. There, algae would accumulate DDT in their tissues.

12 Robert Paine studied sea stars in the intertidal zone along the northern Pacific coast. When he removed sea stars from a study area, their prey, two mussel species, increased exponentially. This crowded out other species, and the overall biodiversity of the community was greatly reduced. In this example, you would call the sea star a keystone species.

16 The emerald ash borer is an invasive insect species that has killed millions of ash trees since it was first identified as a threat in 2002. The U.S. Forest Service has a management plan that includes extensive surveys to detect new infestations, quarantines of materials from already infested forests, public education, chemical treatments, investigation of possible parasites that might attack the ash borer, and an investigation of cultural practices that might help reduce the threat. This control method is an example of biological control.
