Book Description
Among the many outdoor occupations, trapping the furbearing animals is perhaps the most pleasant and in many instances is also very profitable.Although trapping was one of the earliest industries of this country, the occupation has not passed away, along with the vanishing wilderness, for there is more trapping done today than at any time during the past. Scattered all over North America, in both the thickly settled portions and the more remote districts are thousands of trappers who are each season deriving both pleasure and profit from this unique calling.Notice: This Book is published by Historical Books Limited (www.publicdomain.org.uk) as a Public Domain Book, if you have any inquiries, requests or need any help you can just send an email to

Book Description
These chapters provide up-to-date information on nematophagous fungi, particularly those of the Orbiliaceae in Ascomycota, whose asexual states produce nematode-trapping devices. The authors consider fungal-nematode interactions, fossil fungi, the biodiversity, ecology and geographical distribution of nematode-trapping fungi, and their potential use in biocontrol of nematodes, all in detail. Nematode-trapping fungi with adhesive or mechanical hyphal traps are the main focus of this book which begins with an overview of the data on nematode-trapping fungi, including their taxonomy, phylogeny and evolution. Subsequent chapters expand upon the methods and techniques used to study these fascinating fungi. Keys for genera of Arthrobotrys, Drechslerella and Dactylellina, which include all reported species of predatory orbiliaceous fungi are presented and numerous species from these genera are morphologically described and illustrated. The ecology of nematode-trapping fungi is expertly presented: their occurrence and habitats, their geographical and seasonal distribution and the effects of soil conditions and nematode density on their distribution all feature amongst the relevant themes. Further chapters examine the use of nematode-trapping fungi in biological control and the authors consider nematicidal activities in detail, exploring the many compounds from fungi that feature in nematicidal activities and of course useful paths for further study on this topic. This is a highly informative and carefully presented book, providing scientific insight for scholars with an interest in fungi and in biological control of nematodes.

Book Description
How early twentieth century fumigation technologies transformed maritime quarantine practices and inspired utopian visions of disease-free global trade. In the late nineteenth and early twentieth centuries, fumigation technologies transformed global practices of maritime quarantine through chemical and engineering innovation. One of these technologies, the widely used Clayton machine, blasted sulphuric acid gas through a docked ship in an effort to eliminate pathogens, insects, and rats while leaving the cargo and the structure of the vessel unharmed, shortening its time in quarantine and minimizing the risk of importing infectious diseases. In Sulphuric Utopias, Lukas Engelmann and Christos Lynteris examine this overlooked but historically crucial practice at the intersection of epidemiology, hygiene, applied chemistry, and engineering. They show how maritime fumigation inspired utopian visions of disease-free trade to improve global shipping and to encourage universally applicable standards of sanitation and hygiene. Engelmann and Lynteris chart the history of ideas about fumigation, disinfection, and quarantine, and chronicle the development of the Clayton machine in 1880s New Orleans. Built by the Louisiana Board of Health and adapted and patented by Thomas Clayton, the machine offered a barrier against bacteria and pests and enabled a highway to global trade. Engelmann and Lynteris chronicle the Clayton machine's success and examine its competitors, including carbon-based fumigation methods in Germany and the Ottoman Empire as well as the “Sulfurozador” in Argentina. They follow the international standardization of maritime fumigation and explore the Clayton machine's decline after World War I, when visions of “sulphuric utopia” were replaced by a pragmatic acknowledgment of epidemiological complexity.

Book Description
A scientist makes a powerful case that preservation of the integrity of the biosphere is a necessity and an inviolable human right. A century of industrial development is the briefest of moments in the half billion years of the earth's evolution. And yet our current era has brought greater changes to the earth than any period in human history. The biosphere, the globe's life-giving envelope of air and climate, has been changed irreparably. In A World to Live In, the distinguished ecologist George Woodwell shows that the biosphere is now a global human protectorate and that its integrity of structure and function are tied closely to the human future. The earth is a living system, Woodwell explains, and its stability is threatened by human disruption. Industry dumps its waste globally and makes a profit from it, invading the global commons; corporate interests overpower weak or nonexistent governmental protection to plunder the planet. The fossil fuels industry offers the most dramatic example of environmental destruction, disseminating the heat-trapping gases that are now warming the earth and changing the climate forever. The assumption that we can continue to use fossil fuels and “adapt” to climate disruption, Woodwell argues, is a ticket to catastrophe. But Woodwell points the way toward a solution. We must respect the full range of life on earth—not species alone, but their natural communities of plant and animal life that have built, and still maintain, the biosphere. We must recognize that the earth's living systems are our heritage and that the preservation of the integrity of a finite biosphere is a necessity and an inviolable human right.
