An accessible, authoritative look at seahorses, their evolution, biology, habitat, and behavior. Absolutely captivating creatures, seahorses seem like a product of myth and imagination rather than of nature. They are small, elusive, and are named for their heads, which are shaped like miniature ponies with tiny snouts. They swim slowly upright by rapidly fanning their delicate dorsal fin, coil their tails to anchor themselves in a drift, and spend days in a dancing courtship. Afterward, it is the male who carries the female’s eggs in his pouch and hatches the young. Seahorses are found worldwide, and they are highly sensitive to environmental destruction and disturbance, making them the flagship species for shallow-water habitat conservation. They are as ecologically important as they are beautiful. Seahorses celebrates the remarkable variety of seahorse species as well as their exquisiteness. Fifty-seven species, including seadragons and pipefish, are presented in lush, life-size photographs alongside descriptive drawings, and each entry includes detailed and up-to-date information on natural history and conservation. Sara Lourie, a foremost expert on seahorse taxonomy, presents captivating stories of species that range from less than an inch to over a foot in height, while highlighting recent discoveries and ecological concerns. Accessibly written, but comprehensive in scope, this book will be a stunning and invaluable reference on seahorse evolution, biology, habitat, and behavior. Masters of camouflage and rarely seen, seahorses continue to be a fascinating subject of active research. This visually rich and informative book is certain to become the authoritative guide to these charming and unusual wonders of the sea, beloved at aquariums the world over. Praise for Seahorses “This guide covers every one of the 42 known species of seahorses, plus 15 additional relatives, including the seadragon. In addition to beautiful color photographs of all but the rarest species, the descriptions nicely summarize what is known about the distribution, reproduction, and identifying characters of each. The really striking feature, however, is an elegantly simple one: inclusion of a life-sized shadow/silhouette of each species. It is rather astounding to see that some of the pygmy seahorses are literally no larger than the average housefly! . . . Highly recommended.” —Choice
This lavishly illustrated trade reference to mammals, birds, reptiles, amphibians, fishes, and invertebrates features hundreds of glorious photos, masterful illustrations, and informative maps.
Phylogenetic Comparative Methods in R by Liam J. Revell,Luke J. Harmon Pdf
An authoritative introduction to the latest comparative methods in evolutionary biology Phylogenetic comparative methods are a suite of statistical approaches that enable biologists to analyze and better understand the evolutionary tree of life, and shed vital new light on patterns of divergence and common ancestry among all species on Earth. This textbook shows how to carry out phylogenetic comparative analyses in the R statistical computing environment. Liam Revell and Luke Harmon provide an incisive conceptual overview of each method along with worked examples using real data and challenge problems that encourage students to learn by doing. By working through this book, students will gain a solid foundation in these methods and develop the skills they need to interpret patterns in the tree of life. Covers every major method of modern phylogenetic comparative analysis in RExplains the basics of R and discusses topics such as trait evolution, diversification, trait-dependent diversification, biogeography, and visualizationFeatures a wealth of exercises and challenge problemsServes as an invaluable resource for students and researchers, with applications in ecology, evolution, anthropology, disease transmission, conservation biology, and a host of other areasWritten by two of today’s leading developers of phylogenetic comparative methods
Marine Fishes of Florida by David B. Snyder,George H. Burgess Pdf
“A highly useful and interesting reference for ichthyologists, recreational fish enthusiasts and those working in Florida waters . . . a worthy addition.” —Marine Biology Research The most comprehensive book about Florida’s marine fishes ever produced, Marine Fishes of Florida includes hundreds of photographs and descriptions of species you’ll encounter—plus many that are rare—when diving, snorkeling, kayaking, or fishing. Coverage includes both the Atlantic and Gulf coastline, from habitats near the shore to deeper waters. Fishes found in coastal rivers and other brackish waters are fully represented, as are offshore species that venture into Florida’s waters often enough to be called “occasional visitors.” David B. Snyder and George H. Burgess intertwine personal observations with results from research studies to provide accurate—often surprising—details. The result is a set of beautifully succinct identification descriptions coupled with information about each species’ natural history. From the largest sharks to the smallest cryptic gobies, from homely toadfishes to the spectacularly colored reef fishes, this book is certain to help you better understand the fish you’ve seen or hooked. Features of Marine Fishes of Florida include: Color photographs by leading marine photographers Differentiation of adult and juvenile forms Coverage of 133 fish families and hundreds of species Size and geographical range data Natural history and conservation notes Explanations of geologic history and current habitats “Entertaining and informative . . . I think this book will be a great addition to the library of any biologist, fisher, diver or student, and I strongly recommend this book to anyone wishing to expand their knowledge of Florida fishes.” —Environmental Biology of Fishes
Most Australians live in the southern half of their vast continent and within striking distance of the coast. While great recreational and commercial use is made of the reefs that fringe this enormous coastline, our understanding of the reefs is only fragmentary. In this full colour guide to our reefs, leading marine biologists look at our current understanding of the ecology of subtidal reefs and their fisheries.
A fascinating journey with the sea creature that has captured human imagination for thousands of years Poseidon's Steed trails the seahorse through secluded waters across the globe in a kaleidoscopic history that mirrors man's centuries-old fascination with the animal, sweeping from the reefs of Indonesia, through the back streets of Hong Kong, and back in time to ancient Greece and Rome. Over time, seahorses have surfaced in some unlikely places. We see them immortalized in the decorative arts; in tribal folklore, literature, and ancient myth; and even on the pages of the earliest medical texts, prescribed to treat everything from skin complaints to baldness to flagging libido. Marine biologist Helen Scales eloquently shows that seahorses are indeed fish, though scientists have long puzzled over their exotic anatomy, and their very strange sex lives — male seahorses are the only males in the animal world that experience childbirth! Our first seahorse imaginings appeared six thousand years ago on cave walls in Australia. The ancient Greeks called the seahorse hippocampus (half-horse, half-fish) and sent it galloping through the oceans of mythology, pulling the sea god Poseidon's golden chariot. The seahorse has even been the center of a modern-day international art scandal: A two-thousand-year-old winged seahorse brooch was plundered by Turkish tomb raiders and sold to the Metropolitan Museum of Art in New York. A book that is as charming as the seahorse itself, Poseidon's Steed brings to life an aquatic treasure. Seahorses lead quiet lives, tucked away out of sight on the seafloor. It is rare to catch a glimpse of a seahorse in its natural habitat. But even if few have seen one live, these exotic, seemingly prehistoric creatures exist quite vividly in our imaginations and they have mesmerized scientists, artists, and storytellers throughout time with their otherworldly rarity. Poseidon's Steed is a sweeping journey that takes us from the coral reefs and seagrass meadows of Indonesia where many seahorses makes their natural habitat to the back streets of Hong Kong where a thriving black market seahorse trade is concealed. Throughout history, seahorses have surfaced in some unexpected places and Scales also follows the seahorse back in time, from our most rudimentary seahorse imaginings six thousand years ago on cave walls in Australia, to the myths of ancient Greece. Scientists have long puzzled over seahorses' unusual anatomy and their very strange sex lives. And male seahorses are the only males in the animal world that experience childbirth! Seahorses are not what scientists call a "keystone" species. They rely on a healthy ocean to survive, but the marine ecosystem does not rely on them. But their delicate beauty reminds us that we rely on the seas not only to fill our dinner plates, but also to feed our imaginations.
