Atlas of Nevada Conifers is a major scientific contribution to our understanding of the ecology of Nevada. It documents in great detail the distribution of all native conifer species in the state—critical information because of the primary ecological importance of conifers for all organisms and because of the lack of documentation of these distributions in the scientific literature before now. Charlet maps and documents the exact location of herbarium records for 1,600 individual trees. The data found in 23 tables and 22 range maps will serve as a primary reference for botanists, land managers, and conservation biologists for years to come.
Because they prey upon a wide variety of conifers, bark beetles have a major impact upon western forests. In most of the western states, for example, we have witnessed bark beetles in epidemic outbreaks, attacking and damaging ponderosa pine, limber pine, and other hosts.
The ecosystem of bark beetle and host tree is a highly coevolved community of organisms in which the evolution of one member of the community significantly influences the evolution of the other. Largely because of the enormous economic impact these insects exert on the management of our forests, few other such communities have been studied so extensively. Bark Beetles in North American Conifers brings together in one volume both theory and a wealth of empirical data gathered by researchers from all the fields in which bark beetles are studied: ecology, evolutionary biology, population genetics, entomology, and forestry.
Topics covered include the life cycle of bark beetles and their population dynamics, their genetic variation and evolutionary mechanisms, the evolution and systematics of the major groups of bark beetles, pheromone production and its implications for coevolution among these organisms, the interaction between bark beetles and their predators, host resistance and susceptibility, the relationship of parasites and symbiotic micro-organisms in general, and management and control of bark beetles based on sound ecological and evolutionary concepts. The concluding section of the book summarizes the dynamics of the coevolved system of bark beetle and host tree and discusses controversial issues for which this system may provide important answers.
Why did white pine help spark the American Revolution? How did balsam aid the development of germ theory? What does hemlock have to do with making leather? In Conifers of the New England–Acadian Forest, microbiologist Steve Keating explores how conifers influenced the course of human history, writing in a style that is both scientific and accessible.
Keating’s study focuses on one of the most forested and wild ecoregions in North America, which extends into New York, New England, and Canada and includes Acadia National Park. Here, spruces, firs, and cedars of the northern boreal forest mix with hemlocks and pines of more temperate climates. This combination helps create the appearance, aroma, and ecology of the region, and the trees’ unique botanical traits have been ingeniously utilized by numerous peoples including the Iroquois, French explorers, beer brewers, and shipbuilders. Keating concludes with identification guides for the conifers and where they can be found in Acadia National Park.
The second in a series of four illustrated guides to identifying aquatic and standing water plants in the central Midwest, this convenient reference volume includes descriptions, nomenclature, ecological information, and identification keys to plants in all of the monocot families except sedges—which are covered in the first volume in the series—that are found in Kentucky (except for the Cumberland region), Ohio, Indiana, Illinois, Iowa, Missouri, Kansas, and Nebraska.
Monocots covered in this volume include ferns, conifers, grasses, rushes, orchids, duckweeds, irises, sweet flags, arrowheads, aroids, flowering rushes, pipeworts, frog-bits, arrowgrasses, naiads, pickerelweeds, pondweeds, bur reeds, cattails, and yellow-eyed grasses. Robert H. Mohlenbrock includes three types of plants: submergents, those that spend their entire lives with their vegetative parts either completely submerged or at least floating on the water’s surface; emergents, which are typically rooted underwater with their vegetative parts standing out of water; and a third category of plants that live most of their lives out of water, but which may live in water at least three months a year.
With taxa arranged alphabetically, the volume is well organized and easy to use. In addition, basic synonymy, description, distribution, comments, and line drawings show the habits and distinguishing features for each plant. Habitat and nomenclatural notes are also listed, as are the official wetland designations given by the U.S. Fish and Wildlife Service.
Filicineae, Gymnospermae, and Other Monocots, Excluding Cyperaceae is a useful standard reference for state and federal employees who deal with both aquatic and wetland plants and environmental conservation and mitigation issues. It is furthermore an essential guide for students and instructors in college and university courses focusing on the identification of aquatic and wetland plants.
