Book Description
The field of ecological restoration is a rapidly growing discipline that encompasses a wide range of activities and brings together practitioners and theoreticians from a variety of backgrounds and perspectives, ranging from volunteer backyard restorationists to highly trained academic scientists and professional consultants. Ecological Restoration offers for the first time a unified vision of ecological restoration as a field of study, one that clearly states the discipline’s precepts and emphasizes issues of importance to those involved at all levels. In a lively, personal fashion, the authors discuss scientific and practical aspects of the field as well as the human needs and values that motivate practitioners. The book: -identifies fundamental concepts upon which restoration is based -considers the principles of restoration practice -explores the diverse values that are fulfilled with the restoration of ecosystems -reviews the structure of restoration practice, including the various contexts for restoration work, the professional development of its practitioners, and the relationships of restoration with allied fields and activities A unique feature of the book is the inclusion of eight “virtual field trips,” short photo essays of project sites around the world that illustrate various points made in the book and are “led” by those who were intimately involved with the project described. Throughout, ecological restoration is conceived as a holistic endeavor, one that addresses issues of ecological degradation, biodiversity loss, and sustainability science simultaneously, and draws upon cultural resources and local skills and knowledge in restoration work.

Book Description
His compassionate witness is born out of immersion in doggedly bittersweet particulars: the cock-eyed wisdom of 1950s science fiction movies; Do Not Disturb signs; vegetarian physics; the perils of bed-and-breakfast lodging; flying saucer disciples; what to do in case of Rapture; Debbie Fuller, reluctant childhood angel; the theory and practice of Spontaneous Human Combustion. His passionate transformation of that raw data into song - no matter how fragile or raucous - provides irrefutable testimony about the consequences of being nothing less than human, where "every day someone crawls out of his ocean of sleep / and takes those first tottering steps on the planet again / he's playing with real fire." And with Clewell's insistence on the unlikely grace in that condition, along with the generosity of his unabashed inclusiveness, his poetry is a powerful antidote to the bad medicine we're too often asked to swallow.

Book Description
David Clewell’s spirited poems cut through the noise we too often accommodate in our daily lives. Breath by surprising breath, this poet takes us into chambers of the heart that have never been mapped quite this way before. By turns raucous and strangely soothing, narrative and lyrical, Clewell traffics in unlikely and compelling details of our mostly discernible world: a school custodian’s role in the burgeoning Space Race, the vastness of abandoned missile silos, the first lawn flamingos, and the living fossil still using a typewriter.

Book Description
Bacterial plasmids originating in a wide range of genera are being studied from a variety of perspectives in hundreds of laboratories around the globe. These elements are well known for carrying "special" genes that confer important survival properties, frequently neces sary under atypical conditions. Classic examples of plasmid-borne genes are those provid ing bacterial resistance to toxic substances such as antibiotics, metal ions, and bacte riophage. Often included are those determining bacteriocins, which may give the bacterium an advantage in a highly competitive environment. Genes offering metabolic alternatives to the cell under nutritionally stressed conditions are also commonly found on plasmids, as are determinants important to colonization and pathogenesis. It is likely that in many, if not most, cases plasmids and their passenger determinants represent DNA acquired recently by their bacterial hosts, and it is the characteristic mobility of these elements that enables their efficient establishment in new bacterial cells by the process known as conjugation. Whereas many plasmids are fully capable of promoting their own conjugal transfer, others move only with help from coresident elements. The ability of a plasmid to establish itself in a variety of different species is com mon, and recent studies have shown that transfer can in some cases occur from bacterial cells to eukaryotes such as yeast.
