Download The Timber Wolf in Wisconsin PDF Full Free by Richard P. Thiel and published by Univ of Wisconsin Press. This book was released on 1993 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: In early 1958, in the far northern town of Cornucopia, Wisconsin's "last" timber wolf was accidentally run over by an automobile. The "humane" intention to end the animal's suffering produced a grisly aftermath: the wolf survived the impact of the car, was bludgeoned with a tire iron twice but survived, and finally had its throat slit with a restaurant knife. This horrifying scene is certainly an apt (if appalling) symbol of the timber wolf's early fate in Wisconsin. Feared, detested, hunted down for state-authorized bounties, the animal was systematically exterminated as an enemy of man and progress. Yet this bleak chapter in the history of conservation has a happier ending. Seventeen years later, in 1975, the timber wolf had officially reestablished itself and, as a protected species, is now flourishing under the care of Wisconsin's Department of Natural Resources. Few can be more caring than the author, a DNR educator in wildlife management. As an inquisitive teenager, Richard Thiel began his pursuit of the Wisconsin timber wolf's story in the mid-1960s and has been at it ever since. The result is this arresting, intensely readable book, a story of fear, mistrust, and misunderstanding that ends, thankfully, as one of hope and appreciation.

Download The Beaver PDF Full Free by Dietland Müller-Schwarze and published by Comstock Publishing Associates. This book was released on 2011-09-01 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beavers can and do dramatically change the landscape. The beaver is a keystone species—their skills as foresters and engineers create and maintain ponds and wetlands that increase biodiversity, purify water, and prevent large-scale flooding. Biologists have long studied their daily and seasonal routines, family structures, and dispersal patterns. As human development encroaches into formerly wild areas, property owners and government authorities need new, nonlethal strategies for dealing with so-called nuisance beavers. At the same time, the complex behavior of beavers intrigues visitors at parks and other wildlife viewing sites because it is relatively easy to observe. In an up-to-date, exhaustively illustrated, and comprehensive book on beaver biology and management, Dietland Müller-Schwarze gathers a wealth of scientific knowledge about both the North American and Eurasian beaver species. The Beaver is designed to satisfy the curiosity and answer the questions of anyone with an interest in these animals, from students who enjoy watching beaver ponds at nature centers to homeowners who hope to protect their landscaping. Photographs taken by the authors document every aspect of beaver behavior and biology, the variety of their constructions, and the habitats that depend on their presence. Beaver facts: •Just as individual beavers shape their immediate surroundings, so did the distribution of beavers across North America influence the paths of English and French explorers and traders. As a result of the fur trade, beavers were wiped out across large areas of the United States. Reintroduction efforts led to the widespread establishment of these resilient animals, and now they are found throughout North America, Europe, and parts of the southern hemisphere. •Beaver meadows provided early settlers with level, fertile pastures and hayfields. •Based on the fossil record, the smallest extinct beaver species were the size of a muskrat, and the largest may have reached the size of a black bear (five to six times as large as today's North American beavers). Beaver-gnawed wood has been found alongside the skeleton of a mastodon. •Some beavers remain in the home lodge for an extra year to assist their parents in raising younger siblings. They feed, groom, and guard the newborn kits. •In 1600, beaver ponds covered eleven percent of the upper Mississippi and Missouri Rivers' watershed above Thebes, Illinois. Restoring only 3 percent of the original wetlands might suffice to prevent catastrophic floods such as those in the early 1990s.

Book excerpt: The first comprehensive book in more than a century to reveal the diversity and natural history of diving beetles. Among the hundreds of thousands of species of beetles, there is one family, containing some 4,300 species, that stands out as one of the most diverse and important groups of aquatic predatory insects. This is the Dytiscidae, whose species are commonly known as diving beetles. No comprehensive treatment of this group has been compiled in over 130 years, a period during which a great many changes in classification and a near quadrupling of known species has occurred. In Diving Beetles of the World, Kelly B. Miller and Johannes Bergsten provide the only full treatments of all 188 Dytiscid genera ever assembled. Entomologists, systematists, limnologists, ecologists, and others with an interest in aquatic systems or insect diversity will find these extensively illustrated keys and taxon accounts immensely helpful. The keys make it possible to identify all taxa from subfamily to genera, and each key and taxon treatment is accompanied by both photographs and detailed pen-and-ink drawings of diagnostic features. Every genus account covers body length, diagnostic characters, classification, species diversity, a review of known natural history, and world distribution. Each account is also accompanied by a range map and at least one high-resolution habitus image of a specimen. Diving beetles are fast becoming important models for aquatic ecology, world biogeography, population ecology, and animal sexual evolution and, with this book, the diversity of the group is finally accessible.

Book excerpt: Because our chemical environment affects our physical and mental well-being, it is a matter of increasing concern and is therefore attracting much research effort. This timely collection of essays highlights current developments in the field of environmental toxicology. Chapters analyze the carcinogenic, mutagenic, genotoxic, and neurotoxic effects of both anthropogenic and natural toxins in the soil, air, and water around us, as well as in our workplace and diet. The book also examines the effects of toxins on other organisms, as well as the techniques, policies, and management strategies employed in studying and controlling environmental pollutants. It will be an essential reference to a variety of personnel in environmental studies and public health.

Book excerpt: The Pied Flycatcher is one of Europe's best-studied species. The first detailed work on it was begun in the 1930s by German ornithologists, but it was Lars von Haartman's Finnish study that both established long-term research on the species and founded many of the central themes of modern ornithology. Soon after, in the late 1940s, Bruce Campbell set up an intensive project in southwest England, which also still runs to this day. Many other eminent ornithologists followed and in 1979 Arne Lundberg and Rauno Alatalo started their own work in Sweden, Finland and latterly the north of England. A Palaearctic migrant, the Pied Flycatcher is notable for its very variable male plumage and complex territorial and polygynous breeding system. They take readily to nest boxes and have provided excellent opportunities for the study of a wide range of biological problems. This broad review of the species provides not only a detailed biology of this fascinating little bird, but a commentary on many of the most interesting problems in bird behaviour and ecology.
