KIRKUS STARRED REVIEW 2020 Outstanding Science Trade List A Junior Library Guild Selection Natural selection and speciation are all but ignored in children’s nonfiction. To help address this glaring deficiency, award-winning children’s science writer Sneed Collard traveled to the Galapagos Islands to see for himself, where Charles Darwin saw, how new species form. The result is this fascinating story of two species of iguana, one land-based and one marine, both of which developed from a single ancestor that reached the islands millions of years ago. The animals evolved in different directions while living within sight of one another. How is that possible? Collard uses the iguanas to explore Charles Darwin’s great discovery. F&P Level V

When scientist Heather Lynch came across a satellite image of the Antarctic Peninsula's remote Danger Islands streaked with pink, she knew exactly what she was looking at. . . . Poop—guano, to be more specific—and a lot of it. The culprit, she suspected, was a previously unnoticed colony of penguins. A big one. And their favorite food appeared to be pink krill. For a closer look, Heather built a team for an expedition to the Danger Islands, an area notorious for its unpredictable sea ice. Their mission was to count the penguins, determine how long ago the colony was established, and make a case for protecting their habitat from overfishing and other threats. Penguins are particularly important to study because, as indicator species, they can alert scientists to issues affecting the larger ecosystem. Join Heather and her team on a fascinating exploration of these remote islands as they discover a “supercolony” home to one of the world’s largest populations of Adélie penguins. Features team photos from the expedition!

The role of venoms in nature … and in human medicine Why are toxins so advantageous to their possessors as to evolve over and over again? What is it about watery environments that favors so many venomous creatures? Marine biologist Paul Erickson explores these and other questions with astounding images from Andrew Martinez and other top underwater photographers. GREAT for teaching STEM Marine Biology Scorpions and brown recluse spiders are fine as far as they go, but if you want daily contact with venomous creatures, the ocean is the place to be. Blue-ringed octopi, stony corals, sea jellies, stonefish, lionfish, poison-fanged blennies, stingrays, cone snails, blind remipedes, fire urchins—you can choose your poison in the ocean. Venoms are often but not always defensive weapons. The banded sea krait, an aquatic snake, wriggles into undersea caves to prey on vicious moray eels, killing them with one of the world’s most deadly neurotoxins, which it injects through fangs that resemble hypodermic needles.

In what is certain to be the key reference on iguanas for years to come, some of the world's leading experts offer a clear and accessible account of the latest research on the evolution, behavioral ecology, and conservation of these highly visible and increasingly endangered creatures, much loved by professional herpetologists and hobbyists alike. The book begins with an introduction by noted iguana biologist Dr. Gordon Burghardt that examines the state of iguana research—past, present, and future—with an emphasis on social behavior. Three major sections follow, each opening with a synthesis by the volume editors, who survey the current status and likely future direction of investigations in the pertinent area. The first section focuses on different aspects of the taxonomic and morphological diversity of iguanas and includes a complete checklist of species. In the second section, contributors address the behavior and ecology of iguanas and provide compelling evidence that both may be far more complex than previously appreciated. The third and final section, highlighting the threats facing iguana populations today, describes the broad array of innovative conservation strategies that will be needed to help ensure their survival. Illustrated throughout with photographs, distribution maps, tables, and figures, this volume will be the definitive resource for anyone—professional or curious amateur—interested in iguanas.

A beautifully packaged edition of one of García Márquez's most beloved novels, with never-before-seen color illustrations by the Chilean artist Luisa Rivera and an interior design created by the author's son, Gonzalo García Barcha. In their youth, Florentino Ariza and Fermina Daza fall passionately in love. When Fermina eventually chooses to marry a wealthy, well-born doctor, Florentino is devastated, but he is a romantic. As he rises in his business career he whiles away the years in 622 affairs—yet he reserves his heart for Fermina. Her husband dies at last, and Florentino purposefully attends the funeral. Fifty years, nine months, and four days after he first declared his love for Fermina, he will do so again.
