{ "item_title" : "Mayflies Handbook", "item_author" : [" Dave D. Raph "], "item_description" : "Mayflies Handbook is a clear, engaging guide to one of the most important--and most misunderstood--insect groups in freshwater ecosystems. Mayflies can look fragile and fleeting as adults, but their real story happens underwater: months (sometimes years) spent as nymphs in streams, rivers, and lakes, shaping food webs and quietly reflecting the health of the water they live in.This handbook explains mayflies in a way that feels real and useful. You'll learn the full life cycle, the behaviors that help nymphs survive in moving water, and why mayfly hatches can transform entire landscapes in a single evening. Along the way, you'll see why scientists, naturalists, and anglers pay attention to mayflies: they are living links between water quality, habitat structure, and the animals that depend on them.Inside you'll discover:The full mayfly life cycle--egg, nymph, emergence, subimago, adult, and why mayflies have a unique in-between winged stage.Nymph behavior and survival--how different nymph types cling, crawl, burrow, or swim, and what those styles reveal about habitat.Where mayflies live--riffles, pools, lake edges, and the microhabitats that support different species.Why hatches happen--timing, temperature, seasonality, and the cues that synchronize emergence.Their role in freshwater food webs--why fish, birds, amphibians, and other insects depend on mayfly abundance.Mayflies as ecosystem signals--what their presence can suggest about oxygen, pollution sensitivity, and stream stability (without oversimplifying the science).How to observe responsibly--simple methods for watching nymphs, recording emergence events, and learning without damaging fragile stream edges.Written for beginners, students, nature lovers, and anyone curious about rivers and lakes, Mayflies Handbook turns a short-lived insect into a big, satisfying ecological story--one that helps you read freshwater habitats with sharper eyes.If you want to understand mayflies as more than a bug hatch--as essential biology that holds freshwater ecosystems together--Mayflies Handbook is your practical, fascinating guide.", "item_img_path" : "https://covers1.booksamillion.com/covers/bam/9/79/825/022/9798250224512_b.jpg", "price_data" : { "retail_price" : "16.99", "online_price" : "16.99", "our_price" : "16.99", "club_price" : "16.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
