Understanding how a multicellular animal develops from a single cell (the fertilized egg) poses one of the greatest challenges in biology today. Development from egg to adult involves the sequential expression of virtually the whole of an organism's genetic instructions both in the mother as she lays down developmental cues in the egg, and in the embryo itself. Most of our present information on the role of genes in development comes from the invertebrate fruit fly, Drosophila. The two authors of this text (amongst the foremost authorities in the world) follow the developmental process from fertilization through the primitive structural development of the body plan of the fly after cleavage into the differentiation of the variety of tissues, organs and body parts that together define the fly. The developmental processes are fully explained throughout the text in the modern language of molecular biology and genetics. This text represents the vital synthesis of the subject that many have been waiting for and it will enable many specific courses in developmental biology and molecular genetics to focus on it. It will appeali to 2nd and 3rd year students in these disciplines as well as in biochemistry, neurobiology and zoology. It will also have widespread appeal among researchers. Authored by one of the foremost authorities in the world. A unique synthesis of the developmental cycle of Drosophila - our major source of information on the role of genes in development. Designed to provide the basis of new courses in developmental biology and molecular genetics at senior undergraduate level. A lucid explanation in the modern language of the science.

Presents instructions for making various kinds of books including those that carry messages across space and time as well as those that save words, ideas, and pictures.

Winner of the National Outdoor Book Award for Natural History and a New York Times Editors Choice Pick "After reading Super Fly, you will never take a fly for granted again. Thank you, Jonathan Balcombe, for reminding us of the infinite marvels of everyday creatures." —Sy Montgomery, Author of How to Be a Good Creature From an expert in animal consciousness, a book that will turn the fly on the wall into the elephant in the room. For most of us, the only thing we know about flies is that they're annoying, and our usual reaction is to try to kill them. In Super Fly, the myth-busting biologist Jonathan Balcombe shows the order Diptera in all of its diversity, illustrating the essential role that flies play in every ecosystem in the world as pollinators, waste-disposers, predators, and food source; and how flies continue to reshape our understanding of evolution. Along the way, he reintroduces us to familiar foes like the fruit fly and mosquito, and gives us the chance to meet their lesser-known cousins like the Petroleum Fly (the only animal in the world that breeds in crude oil) and the Chocolate Midge (the sole pollinator of the Cacao tree). No matter your outlook on our tiny buzzing neighbors, Super Fly will change the way you look at flies forever. Jonathan Balcombe is the author of four books on animal sentience, including the New York Times bestselling What A Fish Knows, which was nominated for the PEN/E.O. Wilson Award for Science Writing. He has worked for years as a researcher and educator with the Humane society to show us the consciousness of other creatures, and here he takes us to the farthest reaches of the animal kingdom.

These 20 origami planes look great and take to the air just like a bird in flight. You’ll want to construct every one, from a simple glider to the more complicated rocket. Just follow the fun photographs and the information on choosing the right paper, folding, and holding the plane for best flying results. The Hawk’s a classic, with an elegant nose section that resembles a beak. For something more unusual, craft the Hoop, one of the rare circular designs that actually soars. Sleek stylish, and ultramodern, the Needle Dart uses the traditional origami “squash” technique. As your folding skills improve, try the stunning Art Deco Wing, the imaginative Twin (made with multiple sheets of paper), and the unique little Spinner.

Novice fly fisherman start fly tying with a predictable set of materials. Their benches are neatly arranged with small bags of elk hair, pheasant feathers, stray pieces of chenille and yarn. But eventually they find that not only are these materials more expensive than they need to be, they are also largely unnecessary. And so they starts making substitutions, using trial and error to gradually build up a bench of funky, personalized materials that work just as well as what the “experts” recommend. For the first time, here is a book that truly demystifies fly tying, making it accessible to any fisherman with a vice, a hook, a few dabs of glue, and a handful of twisty-ties. Tying legend Jay “Fishy” Fullum brings together a lifetime of substitution experience to give invaluable advice on appropriate substitution materials. He describes how to find them and make them tier friendly, and how to turn them into flies that are practically guaranteed to catch fish.

Not only a fly-tying manual for imitating saltwater baits, but also a study in successful fly design from one of the most influential designers in the country. Learn how to make flies behave like naturals, adapt patterns to imitate numerous baits, and trigger strikes when fish aren't feeding. Covers all important design considerations, including shape, movement and action, color, and sink rate and balance Advice for how to set up a fly box Learn how to tie 21 of the most effective saltwater patterns

Learn a broad range of techniques for dry flies, streamers, and wet flies by tying the modern flies that everyone is talking about. Author Tim Cammisa teaches you how to tie these simple but effective patterns and then how to take the techniques you’ve learned and use them for most of the other core patterns—old and new—that should be in your box. Includes information on the latest materials, tying tips from other tiers, and 16 patterns with recipes and complete step-by-step instructions.
