Kupe and the Corals is the story of Kupe, a young boy who undertakes an amazing voyage of discovery to learn about corals and the importance of coral reefs to all of the many animals that depend upon them. One night while he is fishing with his father, Kupe observes an astonishing event, thousands and thousands of tiny “bubbles” rising to the surface of the waters in the lagoon near where he lives. Kupe is amazed by this sight and wants to learn more about the “strange pink bubbles” that he has captured in an old jam jar. Kupe visits with an elder from his village and a scientist from the nearby marine lab in an attempt to learn more about what he has seen. During his conversations, Kupe learns that what he has captured are tiny coral larvae, baby corals that are produced in the millions over just a few nights each year by the adult corals living in the lagoon. Kupe then goes on to learn more about how corals grow and the importance of corals in building the reefs that provide homes for all of the other wonderful animals that he sees while snorkeling in the lagoon. Now, realizing how important the larvae he has captured are to the health of the coral reef, Kupe happily returns his larvae to the sea. Kupe and the Corals, is the sixth book in the Long Term Ecological Research Network Series.

Mariana is a third grader living in Las Cruces, New Mexico at the northern fringe of the Chihuahuan Desert. One day her class visits Chihuahuan Desert Nature Park to hike to the top of an extinct volcano and see the plant and animal life that is special to this desert. Led by Dr. Whitford, the nature park scientist, the children are challenged to find as many signs of animals living along the trail as they can. Mariana is amazed at all the life around her that was difficult to see at first glance. Adapting to the desert environment, many animals were camouflaged or sought shelter from the sun in burrows. At last atop the volcano, Dr. Whitford tells the children that “This is a great example of an ecosystem that has shifted.” Once grassland, the landscape is now mostly covered in shrubs like creosote bush and mesquite.Suddenly a storm comes up with little warning, and the children rush back to their bus. As the rain subsides the bus driver delivers the unwelcome news that the bus will have to be pulled out of the now muddy road. While waiting for help the children get out of the bus and head for a nearby Playa, a special kind of shallow lake that is formed after a heavy rain. As Mariana wades through the Playa she notices small animals in the water, and scoops one up. Dr. Whitford identifies it as a tadpole shrimp, animals that hatch only when water fills the lakes. At last the bus is pulled out of the mud by a rancher’s tractor, and Mariana returns home to write to her friends about her day in the desert.

Owen, who lives in Colorado, is visiting his cousin Neko at her home in coastal California. He is eager to explore the beach with his cousin and aunt, and they find a large amount of kelp washed ashore after a large storm the previous evening. His curiosity about the kelp leads to an afternoon snorkeling adventure in a kelp forest with his cousin and aunt, and they point out the many creatures that inhabit the underwater “golden forest.” Back on the beach, his marine biologist aunt explains how important the washed-up kelp is to the beach ecosystem, and the children learn how valuable kelp is to the environment both in the water and on the coastal beaches.

One summer morning, Annie and her brother Bradley venture down to a nearby stream to play, but find the water murky and devoid of frogs and minnows. They hear a splashing sound behind them, and are startled to see their neighbor, Ms. Carson, approaching them, wearing rubber boots and carrying a box of test tubes. It turns out Ms. Carson is an aquatic ecologist whose job it is to test the health of local streams. After Annie mentions all the green slime found in the stream, Ms. Carson explains that it is the result of a build up of algae caused by excessive amounts of nutrients flowing into the stream. Ms. Carlson and the kids then gather some water samples in test tubes, to which they add special chemicals that reveal that the water contains excessive amounts of phosphorous and nitrogen. Ms. Carlson explains that these are derived from fertilizer and pesticides that their neighbors have been using to excess. Upon hearing this news, Annie and Bradley begin a special campaign to get their neighbors to reduce the amount of chemicals they use in their lawns and gardens, which results in a healthier stream the following year.
