In this lavishly illustrated, first-ever book on how spider webs are built, function, and evolved, William Eberhard provides a comprehensive overview of spider functional morphology and behavior related to web building, and of the surprising physical agility and mental abilities of orb weavers. For instance, one spider spins more than three precisely spaced, morphologically complex spiral attachments per second for up to fifteen minutes at a time. Spiders even adjust the mechanical properties of their famously strong silken lines to different parts of their webs and different environments, and make dramatic modifications in orb designs to adapt to available spaces. This extensive adaptive flexibility, involving decisions influenced by up to sixteen different cues, is unexpected in such small, supposedly simple animals. As Eberhard reveals, the extraordinary diversity of webs includes ingenious solutions to gain access to prey in esoteric habitats, from blazing hot and shifting sand dunes (to capture ants) to the surfaces of tropical lakes (to capture water striders). Some webs are nets that are cast onto prey, while others form baskets into which the spider flicks prey. Some aerial webs are tramways used by spiders searching for chemical cues from their prey below, while others feature landing sites for flying insects and spiders where the spider then stalks its prey. In some webs, long trip lines are delicately sustained just above the ground by tiny rigid silk poles. Stemming from the author’s more than five decades observing spider webs, this book will be the definitive reference for years to come.
A determined little spider named Walter is trying to make a sturdy web that will stand up to the blustery wind. The webs he makes at first are woven in special shapes--a triangle, a square, a circle--but they are still wibbly-wobbly. Can Walter make a web that is both wonderful and strong? This simple, vibrant adventure is a lively companion to our two previous Tim Hopgood "first books": Wow! Said the Owl, about colors; and Hooray for Hoppy!, about the five senses.

The number Phi, simply defined, is one plus the square root of five, all divided by two. But its myriad occurrences in art, nature, and science have been a source of speculation and wonder for thousands of years. Divine Proportion draws upon both religion and science to tell the story of Phi and to explore its manifestations in such diverse places as the structure of the inner ear, the spiral of a hurricane, the majesty of the Parthenon, and the elusive perfection of the Mona Lisa. A universal key to harmony, regeneration, and balance, Phi is at the heart of a tantalizing story begun on clay tablets in ancient Babylon, and which will continue to be written for centuries to come.
Spiders are identified by the kinds of webs they build. Read about some of the different kinds of webs, from tangled to funnel, and the purposes they serve. Students will also gain an appreciation for these industrious arachnids, which feed on insects and can build beautiful webs in half an hour.
One of the only books to treat the whole spider, from its behavior and physiology to its neurobiology and reproductive characteristics, Biology of Spiders is considered a classic in spider literature. First published in German in 1979, the book is now in its third edition, and has established itself as the supreme authority on these fascinating creatures. Containing five hundred new references, this book incorporates the latest research while dispelling many oft-heard myths and misconceptions that surround spiders. Of special interest are chapters on the structure and function of spider webs and silk, as well as those on spider venom. A new subchapter on tarantulas will appeal especially to tarantula keepers and breeders. The highly accessible text is supplemented by exceptional, high-quality photographs, many of them originals, and detailed diagrams. It will be of interest to arachnologists, entomologists, and zoologists, as well as to academics, students of biology, and the general reader curious about spiders.
From the New York Times-bestselling author of The Secret World of Weather and The Lost Art of Reading Nature’s Signs, learn to tap into nature and notice the hidden clues all around you Before GPS, before the compass, and even before cartography, humankind was navigating. Now this singular guide helps us rediscover what our ancestors long understood—that a windswept tree, the depth of a puddle, or a trill of birdsong can help us find our way, if we know what to look and listen for. Adventurer and navigation expert Tristan Gooley unlocks the directional clues hidden in the sun, moon, stars, clouds, weather patterns, lengthening shadows, changing tides, plant growth, and the habits of wildlife. Rich with navigational anecdotes collected across ages, continents, and cultures, The Natural Navigator will help keep you on course and open your eyes to the wonders, large and small, of the natural world.
Carlos Whittaker equips you with practical steps to destroying the roots of your deep-seated habits so you can get rid of what's holding you back and embrace true freedom in Christ. Are you tired of trying to live for Christ--only to fail time and time again with the same old behaviors? Do you pray for guidance, ask for deliverance, and vow to do better, yet fail to progress? As an author, speaker, podcaster, and communicator for our time, Carlos has lived much of his spiritual life in the spotlight. But, like any Christian, his faith story has had its ups and downs. He spent decades trying to figure out how to be a "better person." Time and time again, he strived for holiness, only to get caught in a cycle of destructive habits, behaviors, and thought patterns. But the buck stops here. Or, rather, the spider is killed here. Throughout Kill the Spider, Carlos walks you through the key aspects of killing the spiders in your own life, including: Confessing the lies you've believed Renouncing the lies that have held you back Rejecting every lie that Jesus has exposed to you Replacing these lies with Jesus's truth In Kill the Spider, Carlos shares everything from hilarious, self-deprecating stories to passion-filled wisdom to teach us that we can't just clear away the pesky cobwebs. Instead, we need to find the spider--the source of the issue--and take it out entirely. Carlos offers a breath of fresh air to any believer looking to finally step into the freedom in Christ. Take a seat, open up your book, and grab a shoe. We're going on a spider hunt.
