This volume reviews recent developments in our understanding of che~ ical signaling in vertebrates. After sections dealing with general princi ples and chemical aspects of vertebrate pheromones, it follows a taxonomic approach, progressing from fish to. mammals. The editors asked a diverse, international group of leading investigators, working on a wide array of vertebrate taxa and specific issues, to consider their efforts from compar ative, evolutionary, and ecological viewpoints. The relative number of manuscripts in each part does not necessarily reflect current intensity of research, since the editors invited speakers who together would provide a balanced and comprehensive overview, while avoiding duplication. Still, the part on mammals is the longest. Fourth in a series dating from 1977, this volume illuminates current trends and likely future developments in the field of chemical signaling in vertebrates. Going back even farther, the first chapter, a personal account of the past quarter century by Dr. Mykytowycz recalls the most important milestones, such as symposia, or the founding of societies and journals. He also credits those investigators who stand out by their seminal studies.

Transport Nodal System provides a comprehensive introduction to the development of transport nodes and nodal systems, focusing on economic, operational, management, planning, policy, regulation and sustainability perspectives. Through a deep analysis on different types of transport nodes from diverse perspectives, this book shows the major issues and challenges that transport node planners, managers, and policymakers face, and how to address them. The book provides a clear framework for identifying the common attributes across all nodes that contribute to the efficient operations, planning, and management of transport facilities. Transport nodes such as seaports, inland terminals, airports, highways, and railroads are hubs in a multimodal transportation network that facilitate the smooth operation of passengers and freight. The book uniquely uses the transport node itself rather than a specific type of structure for a specific type of transport mode as the primary focus of analysis. While stressing the importance of transport nodes in developing efficient logistics and supply chains, the book also demonstrates that transport nodes are geographically embedded within a particular location, and that operations are inevitably affected by local factors, such as culture, the economy, the political and regulatory environment and other institutions.

In the current trend of increasing globalization, relationships are evolving between global and local realities, rich and poor regions of the world and 'old' and 'new' leisure and tourism patterns. The tourist has become an active agent in their travel expereinces, moving between and among multiple localities, in an environment of transnational, interconnected social networks. In order to understand the modern tourist, concepts of mobility have begun to be applied to tourism studies and have questioned whether the word tourism is any longer sufficient to describe the complex socio-political milieu of people on the move. Bringing together theoretical and practical issues, this edited volume analyses tourism's wider role as an agent for the mobile modern population of the world. Themes range from post-modern youth and independent mobility to theoretical texts on hypermobility and citizenship within global space and mobility, media and citizenship. Offering a thought-provoking examination of modern tourism, this will be an important text for students of tourism and human geography as well as tourism professionals.
