Book Description
“The world of jellyfish is brought alive as you never imagined it could be by Lisa-ann Gershwin in this engaging, gripping, and often funny book.” —Callum Roberts, author of The Ocean of Life As our oceans become increasingly inhospitable to life, there is one creature that is thriving in this seasick environment: the beautiful, dangerous, and now incredibly numerous jellyfish. As foremost jellyfish expert Lisa-ann Gershwin describes in Stung!, the jellyfish population bloom is highly indicative of the tragic state of the world’s ocean waters, while also revealing the incredible tenacity of these remarkable creatures. Despite their often dazzling appearance, jellyfish are simple creatures with simple needs: namely, fewer predators and competitors, warmer waters to encourage rapid growth, and more places for their larvae to settle and grow. In general, oceans that are less favorable to fish are more favorable to jellyfish, and these are the very conditions that we are creating through mechanized trawling, habitat degradation, coastal construction, pollution, and climate change. Despite their role as harbingers of marine destruction, jellyfish are truly enthralling creatures in their own right, and in Stung!, Gershwin tells stories of jellyfish both attractive and deadly while illuminating many interesting and unusual facts about their behaviors and environmental adaptations. She takes readers back to the Proterozoic era, when jellyfish were the top predator in the marine ecosystem—at a time when there were no fish, no mammals, and no turtles; and she explores the role jellies have as middlemen of destruction, moving swiftly into vulnerable ecosystems. The story of the jellyfish, as Gershwin makes clear, is also the story of the world’s oceans, and Stung! provides a unique and urgent look at their inseparable histories—and future.

Book Description
Marine Ornamental Species: Collection, Culture and Conservation is a comprehensive resource containing information on the growing and economically important marine ornamental industry. Experts address current issues from a global perspective, covering the full-range of topics from world economics and product demand to aquatic animal health to ethnic and social/cultural concerns. This up-to-date overview will contribute to the creation of an economically and environmentally viable future for this dynamic industry worldwide and for its diverse clientele by: outlining improvements in the methods for the collection and distribution of wild marine ornamental species; providing information to accelerate an increase in the variety, quantity, and availability of cultured marine ornamental species; and encouraging outreach activities in the conservation and husbandry of marine ornamental species The value of and the interest in marine ornamentals from many governments as well as conservation organizations underline the critical need for this book. It is also essential reading for scientists involved in marine biology and conservation issues, aquarists at public and private aquaria, tropical fish farmers, advanced hobbyists, fishery biologists, importers and exporters of marine ornamentals, commercial collectors, veterinarians who specialize in fish disease, and businesses that manufacture or sell aquarium media, equipment, and feed.

Book Description
A breathtaking collection of photographs and expert commentary that shed light on the most mysterious creatures of the deep sea Jellyfish come in a dazzling array of colors, shapes, and sizes, drifting through every ocean, from the surface to the deepest of the deep seas, and are even found in freshwater locations. These ancient creatures, also called sea jellies (they are not, technically, fish), are so otherworldly and luminous that it is no wonder they are often compared to mythical shapeshifters. Some are so delicate that they shatter with the smallest disturbance to the water, while the tenacity of others means they can withstand almost any temperature, any salinity, starvation, and even being dismembered. And some are truly biologically immortal. This visually breathtaking book showcases 100 species of jellyfish within its pages—from the ubiquitous Aurelia to the enigmatic Velella—along with astounding facts about these fascinating marine life-forms. Some are splendid, some strange, some poisonous, some deadly. Some carry surprising secrets and some are barely known, but every one of them is remarkable and has a tale to tell. An introduction by noted expert Lisa-ann Gershwin, with her commentary throughout, invites you into the wondrous world of jellyfish.

Book Description
Discover the edible riches in your backyard, local parks, woods, and even roadside with tips from the author of The Complete Mushroom Hunter. In The Joy of Foraging, Gary Lincoff shows you how to find fiddlehead ferns, rose hips, beach plums, bee balm, and more, whether you are foraging in the urban jungle or the wild, wild woods. You will also learn about fellow foragers—experts, folk healers, hobbyists, or novices like you—who collect wild things and are learning new things to do with them every day. Along with a world of edible wild plants—wherever you live, any season, any climate—you’ll find essential tips on where to look for native plants, and how to know without a doubt the difference between edibles and toxic look-alikes. There are even ideas and recipes for preparing and preserving the wild harvest year-round—all with full-color photography. Let Gary take you on the ultimate tour of our edible wild kingdom! “Gary Lincoff’s book provides a good jumping-off place for those who would like to foster an appreciation for the mostly unlooked-for abundance that surrounds people wherever they are, and an ability to find hidden sustenance in everyday places.” —Englewood Review of Books

Book Description
`Jellyfish', a group that includes scyphomedusae, hydromedusae, siphonophores and ctenophores, are important zooplankton predators throughout the world's estuaries and oceans. These beautiful creatures have come to public attention as featured exhibits in aquaria and in news headlines as invaders and as providers of genes used in biomedical research. Nevertheless, jellyfish are generally considered to be nuisances because they interfere with human activities by stinging swimmers, clogging power plant intakes and nets of fishermen and fish farms, and competing with fish and eating fish eggs and larvae. There is concern that environmental changes such as global warming, eutrophication, and over-fishing may result in increased jellyfish populations. The literature reviews and research papers in this volume explore the interactions between jellyfish and humans. Papers cover the medical aspects of jellyfish stings, jellyfish as human food and jellyfish fisheries, interactions of jellyfish and fish, effects of environmental changes on jellyfish, effects of introduced ctenophores on the Black Sea ecosystem, factors causing increases or concentrations of jellyfish, and others aspects of jellyfish ecology. This is an important reference for students and professional marine biologists, oceanographers, fishery scientists, and aquarists.
