Atlas of the Pig Gut: Research and Techniques from Birth to Adulthood examines the development of the gastrointestinal tract in swine. It focuses on changes occurring during the developmental phase, with an emphasis on the gut that is reflected in alterations of the intestinal mucosa architecture. Led by leading experts in pig digestion research, the book contains descriptions and microphotographs of the most updated research. The changes occurring in the intestine are presented in a comprehensive order, from small magnifications of tissue structures to high magnifications of fragments of epithelium-building cell structures. Additionally, the book highlights the replacement mechanism of epithelial cells during the development of the small intestinal mucosa. This book is the ideal resource for animal science researchers and practitioners. In addition, swine veterinarians and academics will also find it useful due to its helpful, detailed graphics and organized structure.

This volume reviews the historical roots and theoretical foundations of biological systematics in an approachable text. The author outlines the structure and main tasks of systematics. Conceptual history is characterized as a succession of scientific revolutions. The philosophical foundations of systematic research are briefly reviewed as well as the structure and content of taxonomic theories. Most important research programs in systematics are outlined. The book includes analysis of the principal problematic issues as "scientific puzzles" in systematics. This volume is intended for professional taxonomists, biologists of various specialties, students, as well as all those interested in the history and theory of biology and natural sciences. Key Features Considers the conceptual history of systematics as the framework of evolutionary epistemology Builds a hierarchically organized quasi-axiomatic system of taxonomic theory Contends that more reductionist taxonomic concepts are less objective Supports taxonomic pluralism by non-classic philosophy of science as a normal condition of systematics Documents that "taxonomic puzzles" result from conflict between monistic and pluralistic attitudes Related Titles de Queiroz, K. et al., eds.

A growing interest in all things Maya brings an increasing number of visitors to prehistoric Maya ruins and contemporary Maya communities in Guatemala, Belize, El Salvador, western Honduras, the Yucatan Peninsula, and the southern areas of Chiapas and Tabasco, Mexico. For these visitors and indeed everyone with an interest in the Maya, this field guide highlights nearly 100 species of plants and animals that were significant to the ancient Maya and that continue to inhabit the Maya region today.

Drawing from the disciplines of biology, ecology, and anthropology, Victoria Schlesinger describes each plant or animal's habitat and natural history, identifying characteristics (also shown in a black-and-white drawing), and cultural significance to the ancient and contemporary Maya. An introductory section explains how to use the book and offers a concise overview of the history, lifeways, and cosmology of the ancient Maya. The concluding section describes the collapse of ancient Maya society and briefly traces the history of the Maya region from colonial times to the present.
