"The third edition of Ecology and Classification of North American Freshwater Invertebrates continues the tradition of in-depth coverage of the biology, ecology, phylogeny, and identification of freshwater invertebrates from the USA and Canada. This text serves as an authoritative single source for a broad coverage of the anatomy, physiology, ecology, and phylogeny of all major groups of invertebrates in inland waters of North America, north of Mexico." --Book Jacket.

The Field Guide to Freshwater Invertebrates of North America focuses on freshwater invertebrates that can be identified using at most an inexpensive magnifying glass. This Guide will be useful for experienced nature enthusiasts, students doing aquatic field projects, and anglers looking for the best fish bait, lure, or fly. Color photographs and art, as well as the broad geographic coverage, set this guide apart. 362 color photographs and detailed descriptions aid in the identification of species Introductory chapters instruct the reader on how to use the book, different inland water habitats and basic ecological relationships of freshwater invertebrates Broad taxonomic coverage is more comprehensive than any guide currently available

"Part memoir, part manifesto, this exploration of the underside of America's obsession with safety is prompted by the author's visit to a thrillingly alarming adventure playground in Tokyo "How fully can the world be explored, " asks Amy Fusselman ". if you are also trying not to die?" On a visit to Tokyo with her family, Fusselman stumbles on Hanegi playpark, where children are sawing wood, hammering nails, stringing hammocks to trees, building open fires. When she returns to New York, her conceptions of space, risk, and fear are completely changed. Fusselman invites us along on her tightrope-walking expeditions with Philippe Petit and late night adventures with the Tokyo park-workers, showing that when we deprive ourselves, and our children, of the experience of taking risks in space, we make them less safe, not more so. Savage Park is a fresh, poetic reconsideration of behaviors in our culture that -- in the guise of protecting us -- make us numb and encourage us to sleepwalk through our lives. We babyproof our homes; plug our ears to our devices while walking through the city. What would happen if we exposed ourselves, if -- like the children at Hanegi park -- we put ourselves in situations that require true vigilance? Readers of Rebecca Solnit and Cheryl Strayed will delight in the revelations in Savage Park."
