Many mammals like to dig in the dirt, but few call it home. Those that do, such as mole-rats, zokors and tuco-tucos, have developed novel adaptations to their subterranean life, including bones and muscles modified for efficient digging and ways to "see" underground without using their eyes. These unusual traits, adopted independently by unrelated groups around the world, also make subterranean rodents fascinating subjects for biologists. "Life Underground" provides the first comprehensive review of the biology of subterranean rodents. Arranged by topic rather than by taxon to facilitate cross-species comparisons, chapters cover such subjects as morphology, physiology, social behaviour, genetic variation and evolutionary diversification. Two main questions run throughtout the book. First, to what extent has subterranean life shaped the biology of these animals, leading to similar adaptations among otherwise dissimilar species? Second, how have the distinct evolutionary histories of these groups led to different solutions to the challenges posed by life underground?

The taxonomy of recent mammals has lately undergone tremendous revision, but it has been almost four decades since the last update to Timothy E. Lawlor's acclaimed identification guide the Handbook to the Orders and Families of Living Mammals. Integrating the latest advances in research, Douglas A. Kelt and James L. Patton provide this long-overdue update in their new, wholly original work, A Manual of the Mammalia.Complemented by global range maps, high-resolution photographs of skulls and mandibles by Bill Stone, and the outstanding artwork of Fiona Reid, this book provides an overview of biological attributes of each higher taxon while highlighting key and diagnostic characters needed to identify skulls and skins of all recent mammalian orders and most families. Kelt and Patton also place taxa in their currently understood supra-familial clades, and discuss current challenges in higher mammal taxonomy. Including a comprehensive review of mammalian anatomy to provide a foundation for understanding all characters employed throughout, A Manual of the Mammalia is both a user-friendly handbook for students learning to identify higher mammal taxa and a uniquely comprehensive, up-to-date reference for mammalogists and mammal-lovers from across the globe.

Evolutionary Dynamics of the Pocket Gopher Thomomys bottae, with Emphasis on California Populations, by James L. Patton and Margaret F. Smith, offers a groundbreaking examination of one of North America’s most adaptable mammalian lineages. This study integrates morphology, genetics, and ecology to explain how pocket gophers diversified across the varied landscapes of California and the western United States. Patton and Smith analyze patterns of geographic variation, gene flow, and speciation in Thomomys bottae, showing how local ecological pressures—from soil type and vegetation to elevation and climate—shaped the evolutionary pathways of these fossorial rodents. The work emphasizes both microevolutionary processes visible in contemporary populations and the broader historical forces driving divergence across regions. More than a descriptive natural history, this volume demonstrates the methodological advances that come from combining population genetics, systematics, and field ecology. By dissecting the evolutionary dynamics of a species with wide distribution and ecological flexibility, Patton and Smith illuminate general principles of adaptation, isolation, and diversification that extend beyond gophers to broader evolutionary theory. The book stands as both a reference on Thomomys bottae and a model of integrative research, appealing to evolutionary biologists, mammalogists, and ecologists interested in how species evolve in response to environmental heterogeneity.
