This book documents the biology of six species of New World quails that are native to North America north of Mexico (mountain, scaled, Gambel's, California, and Montezuma quails, and the northern bobwhite), three introduced Old World partridges (chukar, Himalayan snowcock, and gray partridge), and the introduced common (ring-necked) pheasant. Collectively, quails, partridges, and pheasants range throughout all of the continental United States and the Canadian provinces. Two of the species, the northern bobwhite and ring-necked pheasant, are the most economically important of all North American upland game birds. All of the species are hunted extensively for sport and are highly popular with naturalists, birders, and other outdoor enthusiasts.

The ten currently recognized species of grouse in North America have played an important role in America’s history, from the famous but ill-fated heath hen, a primary source of meat for the earliest New England immigrants, to the ruffed grouse, currently one of the most abundant and soughtafter upland game birds in more than 40 states and provinces. This book summarizes the ecology, reproductive biology, and social behavior of all ten of the extant North American grouse species. It also describes the current status of grouse populations, some of which are perilously close to extinction. The social behavior of grouse is of special biological interest because among these ten species there is a complete mating system spectrum, from seasonally monogamous pair-bonding to highly promiscuous mating patterns. The latter group illustrates the strong structural and behavioral effects of sexual selection resulting from nonmonogamous mating. These influences reach a peak in the development by some grouse species of engaging in mating “leks,” arena-like competitions performed by males while attempting to attract fertile females, and also provide opportunities for females to select optimum mating partners. These sexual competitions also promote strong differences evolving in sexual signaling behaviors (“displays”) among closely related species. Nevertheless, a relatively high incidence of mating errors and resulting hybridization often occurs in spite of these marked behavioral differences. In addition to a text of 101,000 words, the book includes 16 range maps, 37 line drawings, and 38 photographs by the author, as well as nearly 1,400 literature citations.

A richly illustrated, portable field guide to flycatcher identification The identification of Empidonax flycatchers and pewees can be a daunting challenge for even the most seasoned birder. Field Guide to North American Flycatchers takes bird identification to an entirely new level by training readers to observe subtle differences in structure, color patterns, and vocalizations before delving into the finer details of a particular species. Because the plumages of flycatchers are so similar, this one-of-a-kind guide uses illustrations that highlight slight variances among species that photos often miss. One of the last frontiers of bird identification is now accessible to everyone—once one knows what to look for. Uses a holistic approach that makes flycatcher identification possible even for beginners Features a wealth of beautiful illustrations that depict every species in North America Shows how to observe subtle differences in structure, plumage contrasts, and vocalizations, which together create a distinctive overall impression of the bird Includes detailed audio spectrograms and seasonal distribution maps for each species Shares invaluable tips for successful identification in all kinds of field settings Its compact size and field-friendly layout make it the ideal travel companion for any birder Combined with the second volume in the Field Guide to North American Flycatchers series, which focuses on kingbirds and Myiarchus flycatchers, these companion guides are the most comprehensive and accessible treatments of flycatcher identification to date.

Macroecology is an approach to science that emphasizes description and explanation of patterns and processes at large spatial and temporal scales. Some liken it to seeing the forest through the trees, an apt ecological use of the proverbial phrase. The term itself was introduced to modern literature by our authors James Brown and Brian Maurer, in a seminal science paper in 1989. We then published books by both of these authors, including Brown s Macroecology in 1995, which quickly traveled to the shelf of classics in ecology, credited with cohering and inspiring a subfield of ecology proper.While macroecology is to many a modern subfield, the large-scale perspective it advocates is implicit in earlier publications. For example, in 1898 de Liocourt studied the influence of management practices on the structure of French fir forests, and characterized the distribution of tree size in three different stands. His findings that in natural areas the number of trees declined exponentially with increasing diameter of the trunk allowed him to draw conclusions about the influence of management practices on tree distribution patterns. Similarly, other classic macroecological patterns including the species-area relationship, latitudinal gradient of species richness, relationship between body size and metabolic rate, species-abundance distribution, and species-body size distribution were identified decades, sometimes even centuries ago. Consequently, despite the scant twenty years that has elapsed since the term was coined, macroecology has a deep and rich history."Foundations of Macroecology" traces and coheres that history, charting an evolutionary trajectory to the rigorous macroecological research landscape science enjoys today. The forty-six papers span eight decades, from 1920 to 1998, and include divergent perspectives of space, time, and taxonomic and habitat affiliation. They are organized into two main parts: Macroecology before Macroecology and Dimensions of Macroecology. The latter is further subdivided into six sections reflecting the subject matter: Allometry and Body Size, Evolutionary Dynamics, Abundance and Distributions, Species Diversity, and Methodological Advances. For each reprinted paper, a macroecologist specializing in that area has written original commentary that places the paper in a broader context and explains why it is foundational. "

This volume provides background knowledge useful to those setting out to do genetic studies of aging in mammals, and raises vital questions: How many genes are important in mammalian aging? What are the optimal methods for their study? To what degree are patterns of aging, and patterns of growth and development part of the same process? Do patterns of development predict subsequent patterns of growth and aging? Are there a few fundamental aging processes, or does every biological system age? The rapid rate of progress in this field required a new volume with a new approach, based on the combination of classical genetics and the powerful new tools of molecular genetics. Although mammalian systems are emphasized, representatives of the advanced genetic studies in Drosophila and other model systems are included. The purpose is to enrich and stimulate genetic studies of mammalian aging by suggesting and evaluating future possibilities.
