Published in 2006, Chemical Ecology of Vertebrates was the first book to focus exclusively on the chemically-mediated interactions between vertebrates including fish, amphibians, reptiles, birds and mammals, and other animals and plants. Reviewing research in three core areas - pheromones (where the interactions are between members of the same species), interspecific interactions involving allomones (where the sender benefits) and kairomones (where the receiver benefits), it pulls together information from widely scattered technical literature in many different disciplines into a coherent whole. Chapters on the environment, properties of odour signals, and production and release of chemosignals set the stage for discussion of more complex behavioural topics. While the main focus is ecological, dealing with behaviour and interactions in the field, it also covers chemoreception, orientation and navigation, the development of behaviour and the practical applications of chemosignals.
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.
Strange geese." That was their description when they were discovered in 1520 during Magellan's historic voyage. Today, penguins are familiar to everyone, yet few researchers have observed them in the remote regions in which they live. Written by an ecologist-behaviorist who has worked extensively in the natural penguin habitat, The Behavior of Penguins is the first general work on the entire family of penguins. Numerous and remarkable field photographs document the author's detailed study of the life cycles and breeding patterns of each penguin species. He brings to light their unusual abilities to go with little food for months, to dive deep in the ocean, and to protect themselves in extreme environments. Müller-Schwarze's comprehensive and fascinating account of penguins also emphasizes the urgent need to protect these birds and their natural habitat.
The first volume in this series appeared in 1977, the second in 1980. From these volumes and the present one, some research trends in chemical communication can be perceived. In the 1977 volume, studies on 13 animal taxa were reported. In the present volume, the number is 25. This taxonomie diversi fication of research since the first volume of this series demon strates the wide variety of ecological adaptions, although no new general principles of chemical communication have ernerged. Further more, divergences in chemical comrnunication below the species level have become more apparent. In general, more sophisticated observa tions and techniques have led to greater awareness of the com plexities in chemical communication. As such awareness has also developed in the field of insect chemical communication, there has been a corresponding increase in the identification of the chemical compounds involved. However, in the vertebrates, no such correlation exists; in the present volume, conclusive chemical identifications of semiochemicals are remarkable by their paucity.
Beavers can and do dramatically change the landscape. The beaver is a keystone species their skills as foresters and engineers create and maintain ponds and wetlands that increase biodiversity, purify water, and prevent large-scale flooding. Biologists have long studied their daily and seasonal routines, family structures, and dispersal patterns. As human development encroaches into formerly wild areas, property owners and government authorities need new, nonlethal strategies for dealing with so-called nuisance beavers. At the same time, the complex behavior of beavers intrigues visitors at parks and other wildlife viewing sites because it is relatively easy to observe.In an up-to-date, exhaustively illustrated, and comprehensive book on beaver biology and management, Dietland Muller-Schwarze and Lixing Sun gather a wealth of scientific knowledge about both the North American and Eurasian beaver species. The Beaver is designed to satisfy the curiosity and answer the questions of anyone with an interest in these animals, from students who enjoy watching beaver ponds at nature centers to homeowners who hope to protect their landscaping. Photographs taken by the authors document every aspect of beaver behavior and biology, the variety of their constructions, and the habitats that depend on their presence. Beaver facts: Just as individual beavers shape their immediate surroundings, so did the distribution of beavers across North America influence the paths of English and French explorers and traders. As a result of the fur trade, beavers were wiped out across large areas of the United States. Reintroduction efforts led to the widespread establishment of these resilient animals, and now they are found throughout North America, Europe, and parts of the southern hemisphere. Beaver meadows provided early settlers with level, fertile pastures and hayfields. Based on the fossil record, the smallest extinct beaver species were the size of a muskrat, and the largest may have reached the size of a black bear (five to six times as large as today's North American beavers). Beaver-gnawed wood has been found alongside the skeleton of a mastodon. Some beavers remain in the home lodge for an extra year to assist their parents in raising younger siblings. They feed, groom, and guard the newborn kits. In 1600, beaver ponds covered eleven percent of the upper Mississippi and Missouri Rivers' watershed above Thebes, Illinois. Restoring only 3 percent of the original wetlands might suffice to prevent catastrophic floods such as those in the early 1990s.

Hands-On Chemical Ecology: Simple Field and Laboratory Exercises, a premiere collection of practical exercises in chemical ecology, offers tools and strategies for understanding this young science. The exercises included use general principles and follow a simple structure. Topics examined include birds, fish, insects, mammals, and plant chemistry among others. Additionally, exercises require accessible materials, ensuring that each can be easily modified and completed anywhere in the world with locally existing instruments. This text will be of value to undergraduate and graduates students and high school biology teachers.
