At the Grave of the Unknown Fisherman
by John GierachAt the Grave of the Unknown Fisherman is a journey through the year with America's finest fishing writer, John Gierach. The journey begins with an early spring expedition to Wyoming, where the dirt roads are still covered with a thin sheen of ice that quickly turns to mud underfoot. The conditions are so uninviting that everyone involved agrees they must be crazy to be fishing so early in the season. But, as Gierach observes, "nothing makes a fisherman happier than to have just proved that he must be crazy. " Gierach's fishing year ends with a winter fly-fishing trip in the Colorado Rockies, a time of year when, Gierach says, "it's still possible to have what seems like a whole river all to yourself. " Of course, the chances of catching any fish are small, a situation about which Gierach comments, "Anyone would go fishing thinking he'll catch something. It's when you go figuring you probably won't that you know you've crossed some kind of line. "In between, Gierach entertains us as always, mixing the one-liners about the fishing life with deeper insights into friendship, how we spend our time, and why nature still matters to us. At the Grave of the Unknown Fisherman contains Gierach's trademark blend of humor and acuity. Comparing trout and carp, he says, "If you wanted a fish that could sip white wine and discuss Italian poetry, you'd look for a trout. If you needed a ditch dug, you'd hire a carp. " Commenting on the value of a good map, he observes, "It seems like I've spent half my life trying to locate myself on maps, either just out of curiosity or to answer specific questions like Where the hell am I?' and 'How do I get out of here?' Gierach offers his opinions on the etiquette of sharing secret fishing spots, the ethics of lying to protect these spots, the secretive subculture of bamboo rods, and many other topics important to fishermen everywhere. Above all, however, Gierach understands that the real pleasure in fishing is greater than the sum of its accessories. He describes fish, mountain streams, birch thickets, and the joy of a beautiful day outdoors with a naturalist's eye and appreciation. And he understands fishing like the sage observer that he is: Fishing is one of the few ways I know of to let go of the past, forget about the future, and live in the moment. "Keenly observed and wryly recorded as always, John Gierach's latest book of fishing adventures and misadventures is sure to be enjoyed by anyone who fishes -- and everyone who wishes he fished more.

At the Heart of the Coral Triangle: Celebrating Biodiversity
by Alan J Powderham Sancia van der MeijThe Coral Triangle, straddling the confluence of the Indian and Pacific Oceans, harbours the greatest biodiversity of marine life on the planet. It is home to a wondrous variety, including 75% of the world's coral species and around 2500 species of fish. The biological and environmental diversity is driven by the volcanically active and complex geology of the so called 'Ring of Fire'. Habitats range from underwater slopes of volcanic black sand to extensive coral reefs in atolls and vast calderas. While clearly vulnerable to increasing global threats such as climate change, pollution and overfishing, the Coral Triangle currently features some the richest coral reefs in the world. With stunning photography supported by an engaging and accessible text, this book highlights and celebrates this biodiversity along with the underlying message that it needs our care and protection before it is too late.
At the Size Limit - Effects of Miniaturization in Insects
by Alexey A. PolilovThis book addresses microinsects, their structure and their differences from larger relatives. Moreover, it discusses structural changes that accompany extreme diminution in living organisms, evolutionary inventions that help insects to live in the microworld, and factors that limit the size of animals. It also takes a careful look at the potential benefits of the study of microinsects for solving biotechnological and fundamental scientific problems. Miniaturization is not only a trend in technology: it is also one of the trends in the evolution of life. Many of the problems modern engineers are still struggling with were solved by nature millions of years ago. The world of microscopic organisms, invisible to the naked eye, is all around us. Microinsects -- the extremely diverse range of miniature insects less than a millimeter long -- are one of the most intriguing components of this microworld. Having evolved to the size of unicellular organisms, the smallest insects managed not only to preserve their structural complexity, but also to evolve some novel features not found in larger insects.
At the Top of the Grand Staircase: The Late Cretaceous of Southern Utah (Life of the Past)
by Alan L. Titus and Mark A. LoewenThe Grand Staircase-Escalante National Monument is the location of one of the best-known terrestrial records for the late Cretaceous. Prior fieldwork confirmed the richness of the area, but a major effort begun in the new century has documented over 2,000 new vertebrate fossil sites, provided new radiometric dates, and identified five new genera of ceratopsids, two new species of hadrosaur, a probable new genus of hypsilophodontid, new pachycephalosaurs and ankylosaurs, several kinds of theropods (including a new genus of oviraptor and a new tyrannosaur), plus the most complete specimen of a Late Cretaceous therizinosaur ever collected from North America, and much more. The research documented in this book is rewriting our understanding of Late Cretaceous paleobiogeography and dinosaur phyletics. At the Top of the Grand Staircase: The Late Cretaceous of Southern Utah is a major stepping stone toward a total synthesis of the ecology and evolution of the Late Cretaceous ecosystems of western North America.

The Atlantic Forest: History, Biodiversity, Threats and Opportunities of the Mega-diverse Forest
by Marcia C. M. Marques Carlos E. V. GrelleThe Atlantic Forest is one of the 36 hotspots for biodiversity conservation worldwide. It is a unique, large biome (more than 3000 km in latitude; 2500 in longitude), marked by high biodiversity, high degree of endemic species and, at the same time, extremely threatened. Approximately 70% of the Brazilian population lives in the area of this biome, which makes the conflict between biodiversity conservation and the sustainability of the human population a relevant issue. This book aims to cover: 1) the historical characterization and geographic variation of the biome; 2) the distribution of the diversity of some relevant taxa; 3) the main threats to biodiversity, and 4) possible opportunities to ensure the biodiversity conservation, and the economic and social sustainability. Also, it is hoped that this book can be useful for those involved in the development of public policies aimed at the conservation of this important global biome.
