Bøker i A Guide to Every Family-serien

A lavishly illustrated guide to the seaweed families of the worldSeaweeds are astoundingly diverse. They're found along the shallows of beaches and have been recorded living at depths of more than 800 feet; they can be microscopic or grow into giants many meters long. They're incredibly efficient at using the materials found in the ocean and are increasingly used in the human world, in applications from food to fuel. They're beautiful, too, with their undulating shapes anchored to the sea floor or drifting on the surface. Seaweeds aren't plants: they're algae, part of a huge and largely unfamiliar group of aquatic organisms. Seaweeds of the World makes sense of their complicated world, differentiating between the three main groups-red, green, and brown-and delving into their complex reproductive systems. The result is an unprecedented, accessible, and in-depth look at a previously hidden ocean world.Features close to 250 beautiful color photos as well as diagrams and distribution mapsCovers every major family and genus

"A richly illustrated guide to wasps around the world. Wasps have been around since before the dinosaurs and are one of the world's largest insect groups. More than 150,000 species have been identified, and while the black-and-yellow insect with a cinched waist may be the most familiar, most wasps are tiny parasitoids that use other insects for food. Wasps of the World provides a breathtaking look at the diverse characteristics, habitats, and lifestyles of these extraordinary insects."--Page [4] of cover.
