DOWNLOAD EBOOK →For three years, journalist Richard Louv listened to America by going fishing with Americans. Doing what many of us dream of, he traveled from the Atlantic to the Pacific, from trout waters east and west to bass waters north and south. Fly-Fishing for Sharks is the result of his journey, a portrait of America on the water, fishing rod in hand. To explore the cultures of fishing, Louv joined a bass tournament on Lake Erie and got a casting lesson from fly-fishing legend Joan Wulff He angled with corporate executives in Montana and fly-fished for sharks in California. He spent time with fishing-boat captains in Florida, the regulars who fish New York City's Hudson River, and a river witch in Colorado. He teamed secrets of fishing and living from steelheaders in the Northwest, Bass'n Gals in Texas, and an ice-fisher in the North Woods. Along the way, he heard from one of Hemingway's sons what it was like to fish with Papa and from Robert Kennedy, Jr., how fishing changed his fife. As he describes the eccentricities, obsessions, and tribulations of dedicated anglers, he also uncovers the values that unite them. He reveals the healing qualities of fishing, how it binds the generations, how the angling business has grown, and how the future of fishing is threatened. But most of all, Fly-Fishing for Sharks is about the unforgettable characters Louv meets on the water and the stories they tell. From them, Louv learns about our changing relationship with nature, about a hidden America -- and about himself.

DOWNLOAD EBOOK →Phoridae are probably the insect family with the greatest diversity of larval habits, but the least studied of the large families of flies due to identification difficulties. This book collates what is known about the natural history of the Phoridae world. It reviews eggs and oviposition, larval habits (including saprophages, kleptoparasites, fungus breeders, plant feeders, predator, parasitoids, parasites and enemies), pupae and their enemies, development, adult habits (including feeding, special associations, courtship, mating, phoretic mites and enemies) and ecological aspects. There follows a new user-friendly and extensively illustrated key to world genera and a review of the identification literature for each of the 229 genera recognized. A review of methods and an extensive bibliography complete the work.

DOWNLOAD EBOOK →“Expertly crafted and enjoyable . . . transforms the complicated topics of phenology and climate change. . . . accessible, tangible, and actionable.” —Mark D. Schwartz, editor of Phenology: An Integrative Environmental Science Before you read this book, grab a notebook, go outside, and find a nearby patch of nature. What do you see, hear, feel, and smell? Are there bugs, birds, squirrels, deer, lizards, frogs, or fish, and what are they doing? What plants are in the vicinity, and in what ways are they growing? What shape are the rocks, what texture is the dirt, and what color are the bodies of water? Everything you notice, write it all down. We know that the Earth’s climate is changing, and that the magnitude of this change is colossal. At the same time, the world outside is still a natural world, and one we can experience on a granular level every day. Featuring detailed guidance for keeping records of the plants, invertebrates, amphibians, birds, and mammals in your neighborhood, this book also ponders the value of everyday observations, probes the connections between seasons and climate change, and traces the history of phenology—the study and timing of natural events—and the uses to which it can be put. An expansive yet accessible book, Ground Truth is a guide to paying attention instead of turning away, and to gathering facts from which a fuller understanding of the natural world can emerge. “A unique DIY manual for becoming attuned to the rhythms of the natural world.” —James T. Costa, author of Darwin’s Backyard: How Small Experiments Led to a Big Theory “A necessary book.” —Susan J. Tweit, author of Walking Nature Home: A Life’s Journey

DOWNLOAD EBOOK →The purpose of this book is to summarize new insights on the structure and function of mountain ecosystems and to present evidence and perspectives on the impact of climate change on biodiversity. This volume describes overall features of high-mountain ecosystems in Japan, which are characterized by clear seasonality and snow-thawing dynamics. Individual chapters cover a variety of unique topics, namely, vegetation dynamics along elevations, the physiological function of alpine plants, the structure of flowering phenology, plant–pollinator interactions, the geographical pattern of coniferous forests, terrestrial–aquatic linkage in carbon dynamics, and the community structure of bacteria in mountain lake systems. High-mountain ecosystems are characterized by unique flora and fauna, including many endemic and rare species. On the other hand, the systems are extremely vulnerable to environmental change. The biodiversity is maintained by the existence of spatiotemporally heterogeneous habitats along environmental gradients, such as elevation and snowmelt time. Understanding the structure and function of mountain ecosystems is crucial for the conservation of mountain biodiversity and the prediction of the climate change impacts.The diverse studies and integrated synthesis presented in this book provide readers with a holistic view of mountain ecosystems. It is a recommended read for anyone interested in mountain ecosystems and alpine plants, including undergraduate and graduate students studying ecology, field workers involved in conservational activity in mountains, policymakers planning ecosystem management of protected areas, and researchers of general ecology. In particular, this book will be of interest to ecologists of countries who are not familiar with Japanese mountain ecosystems, which are characterized by humid summers, cold winters, and the snowiest climate in the world.

DOWNLOAD EBOOK →Horticultural sector presents many opportunities for economic development and improving livelihood of growers but several factors constrain production and limit the potential for trade of fruits and vegetables. Tephritid fruit flies constitute a major constraint. They cause enormous losses through direct feeding damage and loss of market opportunities through imposition of quarantine restrictions by importing countries to prevent entry and their establishment. In Africa, several native (Ceratitis and Dacus spp) and exotic (Bactrocera and Zeugodacus spp.) species inflict considerable losses to horticulture causing losses ranging from 30-90%. Over the past 10 years of R&D, extensive information has been generated on bioecology and management of several native and exotic fruit flies in Africa. While several specific reviews have addressed various aspects of the biology, ecology and management of economically important tephritid fruit flies; coverage of African native species has been limited largely to Bactrocera oleae and Ceratitis capitata – which are not economically important species in many Africa countries. Indeed, no book exist that have explicitly addressed economically important African fruit flies and none of the various reviews, have specifically focused on the status of the bioecology, economic impact and management of exotic and native fruit flies – including several potentially invasive Dacus species attacking vegetables - in Africa. This book consolidates this status of knowledge and socio-economic impact of various intervention techniques that are currently being applied across Africa. The timing of the book is especially pertinent due to the changing fruit fly landscape in Africa – caused by arrivals of the highly destructive alien invasives (Bactrocera dorsalis, B. zonata, and B. latifrons) - and the priorities African countries have placed recently on export of fruits and vegetables to international markets. This is an important reference material for researchers, academics and students that are keen at improving horticulture and enhancing food and nutrition security in Africa and beyond.

DOWNLOAD EBOOK →Phenology refers to recurring plant and animal life cycle stages, such as leafing and flowering, maturation of agricultural plants, emergence of insects, and migration of birds. It is also the study of these recurring events, especially their timing and relationships with weather and climate. Phenological phenomena all give a ready measure of the environment as viewed by the associated organism, and are thus ideal indicators of the impact of local and global changes in weather and climate on the earth’s biosphere. Assessing our changing world is a complex task that requires close cooperation from experts in biology, climatology, ecology, geography, oceanography, remote sensing, and other areas. Like its predecessor, this second edition of Phenology is a synthesis of current phenological knowledge, designed as a primer on the field for global change and general scientists, students, and interested members of the public. With updated and new contributions from over fifty phenological experts, covering data collection, current research, methods, and applications, it demonstrates the accomplishments, progress over the last decade, and future potential of phenology as an integrative environmental science.
