Available in PDF, EPUB and Kindle. Book excerpt: "Insects are seldom mentioned in history texts, yet they significantly shaped human history. The Silken Thread: Five Insects and Their Impacts on History tells the stories of just five insects, tied together by a thread originating in the Silk Roads of Asia, and how they have impacted our world. Silkworms have been farmed to produce silk for millennia, creating a history of empires and cultural exchanges; Silk Roads connected East to West, generating trade centers and transferring ideas, philosophies, and religions. The western honey bee feeds countless people, and their crop pollination is worth billions of dollars. Fleas and lice carried bacteria that caused three major plague pandemics, moved along the Silk Roads from Central Asia. Bacteria carried by insects left their ancient clues as DNA embedded in victims' teeth. Lice caused outbreaks of typhus, especially in crowded conditions such as prisons and concentration camps. Typhus aggravated the effects of the Irish potato famine, and Irish refugees took typhus to North America. Yellow fever was transported to the Americas via the trans-Atlantic slave trade, taking and devaluing the lives of millions of Africans. Slaves were brought to the Americas to reduce labor costs in the cultivation of sugarcane, which was itself transported from south Asia along the Silk Roads. Yellow fever caused panic in the United States in the 1700s and 1800s as the virus and its mosquito vector migrated from the Caribbean. Constructing the Panama Canal required defeating mosquitoes that transmitted yellow fever. The silken thread runs through and ties together these five insects and their impacts on history"--

Available in PDF, EPUB and Kindle. Book excerpt: Between 1945 and 1970, Canada’s Department of National Defence sponsored scientific research into the myriad challenges of military operations in cold regions. To understand and overcome the impediments of the country’s cold climate, scientists studied cold-weather acclimatization, hypothermia, frostbite, and psychological morale for soldiers assigned to active duty in northern Canada. Frontier Science investigates the history of military science in northern Canada during this period of the Cold War, highlighting the consequences of government-funded research for humans and nature alike. The book reveals how under the guise of “environmental protection” research, the Canadian military sprayed pesticides to clear bushed areas, used radioactive substances to investigate vector-borne diseases, pursued race-based theories of cold tolerance, and enabled wide-ranging tests of newly developed weapons and equipment. In arguing that military research in northern Canada was a product of the Cold War, Matthew S. Wiseman tackles questions of government power, scientific authority, and medical and environmental research ethics. Based on a long and deep pursuit of declassified records, archival sources, and oral testimony, Frontier Science is a fascinating new history of military approaches to the human-nature relationship.

Available in PDF, EPUB and Kindle. Book excerpt: Insects as a group occupy a middle ground in the biosphere between bacteria and viruses at one extreme, amphibians and mammals at the other. The size and gen eral nature of insects present special problems to the student of entomology. For example, many commercially available instruments are geared to measure in grams, while the forces commonly encountered in studying insects are in the mil ligram range. Therefore, techniques developed in the study of insects or in those fields concerned with the control of insect pests are often unique. Methods for measuring things are common to all sciences. Advances sometimes depend more on how something was done than on what was measured; indeed a given field often progresses from one technique to another as new methods are discovered, developed, and modified. Just as often, some of these techniques fmd their way into the classroom when the problems involved have been suffici ently ironed out to permit students to master the manipulations in a few labo ratory periods. Many specialized techniques are confined to one specific research laboratory. Although methods may be considered commonplace where they are used, in another context even the simplest procedures may save considerable time. It is the purpose of this series (1) to report new developments in methodology, (2) to reveal sources of groups who have dealt with and solved particular entomological problems, and (3) to describe experiments which might be applicable for use in biology laboratory courses.
