Book Description
For most of us the word "desert" conjures up images of barren wasteland, vast, dry stretches inimical to life. But for a great array of creatures, perhaps even more plentiful than those who inhabit tropical rainforests, the desert is a haven and a home. Travel with Michael Mares into the deserts of Argentina, Iran, Egypt, and the American Southwest and you will encounter a rich and memorable variety of these small, tenacious animals, many of them first discovered by Mares in areas never before studied. Accompanying Mares on his forays into these hostile habitats, we observe the remarkable behavioral, physiological, and ecological adaptations that have allowed such little-known species of rodents, bats, and other small mammals to persist in an arid world. At the same time, we see firsthand the perils and pitfalls that await biologists who venture into the field to investigate new habitats, discover new species, and add to our knowledge of the diversity of life.
Filled with the seductions and trials that such adventures entail, A Desert Calling affords an intimate understanding of the biologist's vocation. As he astonishes us with the range and variety of knowledge to be acquired through the determined investigation of little-known habitats, Mares opens a window on his own uncommon life, as well as on the uncommon life of the remote and mysterious corners of our planet.

Desert adventures with biology.......2002-12-18
It is interesting that this book is being published for the first time since much of the material comes from Professor Mares's work with small desert mammals during the seventies. Mares, who is the Curator of Mammals and Director of the Sam Noble Oklahoma Museum of Natural History at the University of Oklahoma is also the author of Encyclopedia of Deserts (1999). Perhaps he has been too busy to publish what is essentially a popular work. Since the book includes reports on his field work and that of his students into the nineties, maybe this book is a way of rounding out a career.
Regardless of the reason for the material finally finding publication, we are the better for it. Part memoir, part fieldwork journal, and part travelogue, A Desert Calling is that rare scientific tome that engages our adventurous spirit through a vivid and lively presentation while at the same time giving us a concrete sense of the animals and their habitats. As the late Stephen Jay Gould expresses it in the Foreword, Mares writes with "a verbal freshness (and a fine sense for a good yarn) that will delight even the most sophisticated urbanite...." (p. xi)
The book is also beautifully edited and presented with handsome page layouts. Chapter beginnings and major paragraph breaks feature photo icons of the small desert rodents that were the focus of much of Mares's work. The text is interspersed with black and white photos of animals and the forbidding desert climes that he and his fellow field biologists encountered on three continents. There are four maps to help us locate these places. Mares includes an appendix giving both the common and scientific names of species mentioned in the text organized geographically. There are 14 pages of suggestions for further reading ordered by chapter.
Mares's travels include the Sonoran and Mojave deserts in the American southwest, the Monte Desert and the Patagonia and Caatinga regions in South America, and the Dasht-i-Kavir in Iran and the Sahara in Egypt. He traveled to Argentina during the years of the Dirty War and was in Iran just before the fall of the Shah and the rise of the Ayatollah Khomeini. He lived through blinding sandstorms and heat so oppressive that he sought relief in pig water and mud laced with pig feces. He endured stings from hoards of vicious insects in landscapes nearly as barren as the moon with shaded Fahrenheit temperatures in the 130's. (p. 181) He encountered bureaucratic obstruction that would try the patience of a saint, poverty that would move even Scrooge to tears, and enough danger to satisfy a jaded CIA agent.
But above all he reports on the animals and how they live. He includes the discovery of a number of new species and genera of mammals, and three major ecological findings, all having to do with convergent evolution. Seeking the animal in the Monte Desert of Argentina that is the analogue of the kangaroo rat of the North American Sonoran Desert he inexplicably finds none. But then by happenstance he becomes aware of an extinct marsupial skeleton collected by famed biologist George Gaylord Simpson that fits the expected convergence to a tee. Indeed the animal had gone extinct only a million years previous which explained why none of the other rodents had yet evolved to fill that niche. (p. 126)
Mares also demonstrates that the jerboa of the Sahara, which is taxonomically nearly identical to the kangaroo rat, a fact well know for many decades, is not the whole story. It turns out that their diets and therefore some parts of their anatomy, including their teeth of course and presumably their digestive systems, are more different than was previously supposed. Mares realized this because he discovered that while kangaroo rats are seed specialists, the convergent jerboas have a more varied diet including plants and even crickets. After some further research, Mares understood that the bipedal adaption of the jerboas and kangaroo rats is an adaptation to allow them to run (hop!) away from predators.
To my mind the most interesting discovery was that the rock hyraxes of Africa have a nearly exact counterpart in the rock cavies of Caatinga in Argentina. As Mares expresses it (p. 202), they "are about as distantly related as mammals can be, [but they] not only look alike, but are similar in almost all aspects of their reproduction, ecology, and behavior." In a splendid example of natural selection at work, Mares points to their unique but similar rock pile environments as strongly shaping their morphology and behavior.
Perhaps what Mares does best that other scientists that work in distant places do not always do so well is to shed light on not only the climate and the species but on the local people, what they are like and how they live. His description of the isolation of some of the people in the Monte and the Chaco ("El Impenetrable" in Spanish, which Mares calls a "land of thorns") in Argentina is almost like reading about lost tribes from ancient times. His encounters with locals sometimes reminded me of something from a wild west movie of my childhood.
Also very interesting was his account of the discovery of a new species, the golden vizcacha rat on pages 257-259. I also liked his touching recollection of coming home for Halloween just in time to join his two boys for trick or treating on page 275.
Bottom line: this engaging and colorful book allows us to experience the hard work, pure drudgery, quiet contentment, and the sometimes thrilling exhalation of field work through the eyes of a working scientist with a gift for exposition.
Two books for the price of one.......2002-08-13
Michael Mares' book grew on me enormously as I read it. The combination of his series of wild experiences along with his enthusiasm for the research puzzles he confronts made this book read almost like a double thriller. This could be read as a travel book, very much like Eric Hansen's books, with a bonus of learning a lot about nature, evolution, ecology, etc. Or, it could be read as a book of ecology and evolution with the bonus of extraordinary adventures. At first, I kept on reading the book more for the adventures and then realized that my excitement about the science was growing. I have never had a book sneak up on me in this way.
The Beauties and Dangers of the Desert.......2002-05-19
We are quite used to hearing about the rainforest and the worries about its loss. We hear less about the loss of deserts. Let the military test there, let off-track entertainment vehicles bounce there, let toxic wastes accumulate there; they are not good for much else, goes the common view. They are uncomfortable places to visit, and they can't be turned to agriculture. Michael A. Mares, in _A Desert Calling: Life in a Forbidding Landscape_ (Harvard), has a completely different view. Mares has spent his professional life studying the deserts of the United States, Argentina, Iran, and Egypt. He undoubtedly knows plenty about plants, insects, birds, and snakes of these areas, but he is a specialist in the mammals that have evolved to live in such harsh conditions. Desert rats, mice, armadillos, and gerbils have been his study, and he has here (note the double meaning of the title) assembled a description of his life's work, as well as an attempted explanation of just why he has spent so much time in places the rest of us could not stand. His thoughtful and funny stories are a sort of autobiography, and he has much to tell us about the exotic animals that he wants better appreciated.
There are some peculiar beasts out there. The kangaroo rat has a nose exquisitely tuned to find buried seeds, and can filter sixty seeds from sand in a second. There are penguins in the desert in Patagonia. There are a few rodents on different continents who can live on the leaves of the saltbush, leaves that have a protective outer layer of cells full of salt. They have special teeth, or in one case, special dental hairs, that strip away the inedible layer to get to the green below. There are deadly assassin bugs. Mares describes staying in some of the most unpleasant regions of the world, and admits that when he is busy with academia and home, he longs to get to the desert, but it works vice versa, too. He is almost killed by fungus infesting his lungs after climbing through guano deposits in a New Mexico cave. He is nearly crushed by trees falling during a storm on a bat hunt in Costa Rica. Some of the most surprising specimens described here are humans, and Mares has plenty of funny stories.
_A Desert Calling_ is full of light moments, and near-disasters that are pleasant to recall because they are over. However, Mares has a good deal serious to say about the study of desert animals, and in the larger view, about taxonomy in general. "If you do not know the taxonomy and systematics of the organisms you study - if you cannot identify them correctly and understand how they are related - then you cannot study them in any meaningful manner." Research in "bigger" topics such as ecology is only possible when taxonomists have gone to the field beforehand and identified one creature from another and settled their ranges and evolutionary relationships. Mares has found and been responsible for the first scientific descriptions of many mammals, and knows that there are still plenty out there which have yet to be properly catalogued and studied. Over and over, he comes across specimens about which no one has basic answers: Are they diurnal or nocturnal? Do they live in colonies? Do they hibernate? What do they eat? There is an enormous amount of basic science brightly reported here, and an enormous amount that is yet to be done.

NOT A TRUE DISASTER BOOK.......2006-12-28
A range of disasters is covered here. Asimov begins with threats at the cosmic level, such as a reverse big bang, and works down to disasters that would destroy the solar system, and then only the earth. The last category include the least destructive and most managable dangers: those that disrupt our lives but would not wipe us out, such as pollution.
It became clear to me early on that this is not a true disaster book. We learn little about what these catastophes would actually do and how they might play out. Instead, Asimov concentrates on the scientific and mathematical possibilities and probabilities involved. A bizzare tone of optimism also permeates the book, as the author believes every problem can be solved and every danger avoided, if only mankind works together for the good of humanity. Not likely!
The young (or old) scientist with a global perspective will find this a great read, and all readers will learn a thing or two about how our end might come. But this is not really a disaster book by any means
How will life end?.......2001-08-30
In this book, Asimov explores and analyzes the different ways the world, or civilzation, could end (the "catastrophes") and estimates the likelihood and time frame of each one of them. He goes all the way from the macro-catastrophes (heat death of the universe) to the micro-catastrophes (disease and political turmoil).
Very interesting book that brings science and a dose of reality into this consideration of the ultimate demise of mankind.
Will humanity overcome?.......2000-11-05
I was pleasantly surprised by this book(Dutch translation). I had never before read Asimov, and although I imagined him as a "serious" science-fiction author, the subject and title of this book made me uncertain about what to expect... Would it go down the popular road of feeding on people's fear? As it turns out, there was no need to worry. Asimov uses a nicely balanced approach to this mass-appeal theme to touch many fields of science and even culture. His message is not one of hysteria, but a message of hope. He presents himself as a true Homo Universalis of our time. Not in the sense that he pretends to know everything about anything, the sort of omni-knowledge that died after the Renaissance. But in the sense that he argues like a true World Citizen. A member of the human race instead of belonging to this or that nation/religion/sex/whatever. Of course, the subject of the book lends itself very well for this. So my impression is that Asimov found it more important to awake this feeling in the readers, than to write a sort of disaster-encyclopedia. The book is meant to assist us in becoming conscious about our position in space and time. About our relation to the past, the future and all the phenomenons in the Universe that completely outscale us in size, violence and duration. It is meant to make us feel tiny and insignificant in one way. But certainly also to unite us in a collective battle against the indifferent laws of nature and evolution.
I would recommended this book to anyone with a broad view on the world around us.

Book Description
Metal matrix composites are making tangible inroads into the "real" world of engineering. They are used in engineering components such as brake rotors, aircraft parts, combustion engines, and heat sinks for electronic systems. Yet, outside a relatively limited circle of specialists, these materials are mostly unknown. Designers do not as a rule think of using these materials, in part because access to information is difficult as these materials have not really entered engineering handbooks.
Metal Matrix Composites in Industry is thus useful to engineers who wish to gain introductory knowledge of these materials and who want to know where "to find" them. Additionally, it provides researchers and academics with a survey of current industrial activity in this area of technology.

Book Description
Taking the mystery out of Shakespeare - not the magic. This translation of HAMLET into contemporary English, alongside the original text, has modernized the difficult passages and expressions which used to make Shakespeare's language a challenge. This unique translation is not a literal prose version. On the contrary, it retains the flavor and rhythm of the original, letting the reader experience the play in the same enjoyable way an Elizabethan audience did. The text is immediately clear to today's readers, making those tedious footnotes unnecessary. A glossary of place names and mythological references is included. A separate Teacher's Manual is available (ISBN 9781885564092).
