What determines the number and size of the seeds produced by a plant? How often should it reproduce them? Why and how are seeds dispersed, and what are the implications for the diversity and composition of vegetation? These are just some of the questions tackled in this wide-ranging review of the role of seeds in the ecology of plants. The text encompasses a wide range of concepts of general relevance to plant ecology, reflecting the central role that the study of seed ecology has played in elucidating many fundamental aspects of plant community function.
Alexander the Great led one of the most successful armies in history and conquered nearly the entirety of the known world while wearing armor made of cloth. How is that possible? In Reconstructing Ancient Linen Body Armor, Gregory S. Aldrete, Scott Bartell, and Alicia Aldrete provide the answer. An extensive multiyear project in experimental archaeology, this pioneering study presents a thorough investigation of the linothorax, linen armor worn by the Greeks, Macedonians, and other ancient Mediterranean warriors. Because the linothorax was made of cloth, no examples of it have survived. As a result, even though there are dozens of references to the linothorax in ancient literature and nearly a thousand images of it in ancient art, this linen armor remains relatively ignored and misunderstood by scholars. Combining traditional textual and archaeological analysis with hands-on reconstruction and experimentation, the authors unravel the mysteries surrounding the linothorax. They have collected and examined all of the literary, visual, historical, and archaeological evidence for the armor and detail their efforts to replicate the armor using materials and techniques that are as close as possible to those employed in antiquity. By reconstructing actual examples using authentic materials, the authors were able to scientifically assess the true qualities of linen armor for the first time in 1,500 years. The tests reveal that the linothorax provided surprisingly effective protection for ancient warriors, that it had several advantages over bronze armor, and that it even shared qualities with modern-day Kevlar. Previously featured in documentaries on the Discovery Channel and the Canadian History Channel, as well as in U.S. News and World Report, MSNBC Online, and other international venues, this groundbreaking work will be a landmark in the study of ancient warfare.

Australia’s Submariners are a group with an extremely strong sense of identity that goes well beyond occupational comradeship or the esprit de corps of military life in peace or war. Since 1914, the unique skills, attitudes, values and demands of the work they do and the environment in which they do it have forged unparalleled camaraderie. A camaraderie that extends beyond nationality, embracing submariners past and present of every other nation. No one but submariners understand the experience of diving deep beneath the waves in technology filled tubes of steel, each submariner totally dependent on the other for a safe return to the surface. The ethos of Australia’s submariners is based upon these factors and remains strong even when they leave the sea and take up other occupations. Australia’s future submarines will certainly present challenges in terms of sophistication, technology and capability however the characteristics of our submariners evolved over previous generations will remain much the same; trained and equipped to meet the challenges; just as they have been met and surmounted so many times, in silence, over a century of service.
