HONOLULU (AP) - Marine biologists are using electronic tracking devices to examine how climate change and other human impact on the oceans have affected animal behavior.

The Honolulu Star-Advertiser reports (http://bit.ly/1Hl3nrX ) scientists are gathering data transmitted from lightweight tags that are placed on the animals. The tags weigh less than a penny, can last more than 10 years and can be attached to almost any species.

University of Hawaii researcher Kim Holland says there are experiments going on all over the world using the tracking devices.

Scientists have learned new things about how far yellowfin tuna can swim, how often tiger sharks visit near-shore reefs, and how some endangered marine animals migrate.

The advances in tracking have been described in a research paper published online June 12 in the journal Science.
