A thoughtfully organized and attractively presented example of science in the field. .
A young scientist’s doctoral research reveals a surprising relationship between sea grasses and sea otters in a California bay.
Valuable sea grasses in Elkhorn Slough, in Northern California, were thriving in spite of heavy nutrient pollution from nearby Salinas Valley farms. When Brent Hughes began his investigation of this mystery, he looked at things directly affecting sea-grass growth, such as weather patterns. It wasn’t until he compared sea grass cover with otter population that he found a match. In discussions with other researchers, the young white biologist learned that otters like to eat big, meaty crabs, which feed on sea hares, a type of sea slug that in turn feeds on algae growth that smothers the grasses. Following usual procedures, he then designed experiments to prove his hypothesis that the thriving otter population made the sea grass flourish. This intriguing description of the problem he saw and his research process is a model of the scientific method. Interspersed with chapters describing the mystery, the development of the hypothesis, the proof, and the larger idea of “trophic cascades” (interactions among predators and prey that begin at the top of the food chain) are sections about otters and about sea-grass science in general. A map, ample photographs, and an attractive design add appeal, and there are sensible suggestions for environmental protection.

Wordplay and wry wit put extra fun into a trove of fundamental knowledge.
With an amped-up sense of wonder, the Science Guy surveys the natural universe.
Starting from first principles like the scientific method, Nye and his co-author marvel at the “Amazing Machine” that is the human body then go on to talk up animals, plants, evolution, physics and chemistry, the quantum realm, geophysics, and climate change. They next venture out into the solar system and beyond. Along with tallying select aspects and discoveries in each chapter, the authors gather up “Massively Important” central concepts, send shoutouts to underrecognized women scientists like oceanographer Marie Tharp, and slip in directions for homespun experiments and demonstrations. They also challenge readers to ponder still-unsolved scientific posers and intersperse rousing quotes from working scientists about how exciting and wide open their respective fields are. If a few of those fields, like the fungal kingdom, get short shrift (one spare paragraph notwithstanding), readers are urged often enough to go look things up for themselves to kindle a compensatory habit. Aside from posed photos of Nye and a few more of children (mostly presenting as White) doing science-y things, the full-color graphic and photographic images not only reflect the overall “get this!” tone but consistently enrich the flow of facts and reflections. “Our universe is a strange and surprising place,” Nye writes. “Stay curious.” Words to live by.

BOOK REVIEW
“In 1875 there were perhaps fifty million of them. Just twenty-five years later nearly every one of them was gone.” The author of many nonfiction books for young people (Bridges; Truck; Giants of the Highways, etc.) tells the story of the American bison, from prehistory, when Bison latifrons walked North America along with the dinosaurs, to the recent past when the Sioux and other plains Indians hunted the familiar bison. Robbins uses historic photographs, etchings, and paintings to show their sad history. To the Native Americans of the plains, the buffalo was central to their way of life. Arriving Europeans, however, hunted for sport, slaughtering thousands for their hides, or to clear the land for the railroad, or farmers. One telling photo shows a man atop a mountain of buffalo skulls. At the very last moment, enough individuals “came to their senses,” and worked to protect the remaining few. Thanks to their efforts, this animal is no longer endangered, but the author sounds a somber note as he concludes: “the millions are gone, and they will never come back.” A familiar story, well-told, and enhanced by the many well-chosen period photographs.
