{ "item_title" : "The Invisible Work of Fish", "item_author" : [" Lou Herfurth "], "item_description" : "Fish do far more than live in water. They shape the worlds around them.They transport nutrients, disturb sediments, fertilize coral reefs, disperse seeds, connect rivers with the sea, and carry carbon into deeper water. Wherever fish feed, rest, migrate, or die, they leave ecological traces behind. Many of these processes remain almost invisible, even though entire ecosystems depend on them.The Invisible Work of Fish explores these hidden functions through 18 remarkable examples from aquatic ecology. Drawing on scientific research, Lou Herfurth shows how fish drive nutrient cycles, influence food webs, reshape habitats, and move matter across landscapes.A sleeping site on a coral reef can become a nutrient hotspot. Migrating fish can carry biological material against the direction of water flow. Parrotfish help create sediment. Fruit-eating fish disperse seeds through flooded forests. Even the presence of predators can alter what nutrients prey fish release into their environment.This is a book about fish as transporters, recyclers, landscape engineers, and ecological connectors. It also asks a question that matters increasingly for conservation: What disappears from an ecosystem when the fish themselves disappear?A visually rich, accessible science book for readers interested in fish, rivers, oceans, ecology, biodiversity, and the hidden processes that keep aquatic ecosystems functioning.", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/9/79/816/720/9798167204034_b.jpg", "price_data" : { "retail_price" : "14.99", "online_price" : "14.99", "our_price" : "14.99", "club_price" : "14.99", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
