Measuring the consequences of clear-cutting on the Osa Peninsula (Costa Rican Forest)

1989 – This is my first recording form the Osa Peninsula of Costa Rica, when the tropical forest had not yet been clear-cut

1996 – After the site was clear-cut, the density and diversity of the biophony dropped off, showing the extreme stress on that habitat.

Recording the sound of a dying reef near the island of Vanua Levu (Fijian Reef)

1995 – We recorded two sections of coral reef: one alive, and one dead. This portion of the reef was still healthy. We recorded 11 different species of fish and one snapping shrimp.

1995 – About 400 yards away, the same reef was already bleached and dying from ocean warming, acidification, and pollution. We found no fish living here.
