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

Download or read book Chasing Guano: The Discovery of a Penguin Supercolony (How Nature Works) written by Helen Taylor and published by Tilbury House Publishers and Cadent Publishing. This book was released on 2024-07-30 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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!

Download or read book Don't Mess with Me: The Strange Lives of Venomous Sea Creatures (How Nature Works) written by Paul Erickson and published by Tilbury House Publishers and Cadent Publishing. This book was released on 2018-12-04 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
