This book examines behavioral adaptations of tropical birds in timing of breeding, life history traits, mating systems and parental care, territoriality, communication, and biotic interactions, and emphasizes the many gaps in our knowledge of tropical birds. We urge students and researchers in temperate and tropical regions alike to realize the potential they have for improving our knowledge of avian adaptations far beyond what is currently accepted as gospel. Time is running out.

Advances in the Study of Behavior was initiated over 40 years ago to serve the increasing number of scientists engaged in the study of animal behavior. That number is still expanding. This thematic volume makes another important "contribution to the development of the field" by bringing together material that aggregates studies conducted on the behavior of tropical animals. Advances in the Study of Behavior is now available online at ScienceDirect--full-text online from volume 30 onward.

Wussten Sie, dass Sie mit einem Röhrling näher verwandt sind als mit einem Gänseblümchen oder Vögel den Krokodilen näher sind als Eidechsen? In den letzten 30 Jahren sind die Methoden der Klassifikation des Lebens völlig neu überdacht worden. Das Resultat stellt die bisherige Einteilung der mehr als 2 Millionen bekannten Arten auf den Kopf. Das Buch hilft, die organismische Vielfalt zu bewältigen, indem wesentliche Einteilungs- und Ordnungskriterien vorgestellt und bedeutende stammesgeschichtliche Entwicklungslinien diskutiert werden.

Sexual Selection: Perspectives and Models from the Neotropics presents new sexual selection research based upon neotropical species. As neotropical regions are destroyed at an alarming rate, with an estimated 140 species of rainforest plants and animals going extinct every day, it is important to bring neotropical research to the fore now. Sexual selection occurs when the male or female of a species is attracted by certain characteristics such as form, color or behavior. When those features lead to a greater probability of successful mating, they become more prominent in the species. Although most theoretical concepts concerning sexual selection and reproductive strategies are based upon North American and European fauna, the Neotropical region encompasses much more biodiversity, with as many as 15,000 plant and animal species in a single acre of rain forest. This book illustrates concepts in sexual selection through themes ranging from female cryptic choice in insects, sexual conflict in fish, interaction between sexual selection and the immune system, nuptial gifts, visual and acoustic sexual signaling, parental investment, to alternative mating strategies, among others. These approaches distinguish Sexual Selection from current publications in sexual selection, mainly because of the latitudinal and taxonomic focus, so that readers will be introduced to systems mostly unknown outside the tropics, several of which bring into question some well-established patterns for temperate regions. Synthesizes sexual selection research on species from the Neotropics Combines different perspectives and levels of analysis using a broad taxonomic basis, introducing readers to systems mostly unknown outside the tropics and bringing into question well-established patterns for temperate regions Includes contributions exploring concepts and theory as well as discussions on a variety of Neotropical vertebrates and invertebrates, such as insects, fish, arthropods and birds

The purpose of migration, regardless of the distance involved, is to exploit two or more environments suitable for survival or reproduction over time, usually on a seasonal basis. Yet individual organisms can practice the phenomenon differently, and birds deploy unique patterns of movement over particular segments of time. Incorporating the latest research on bird migration, this concise, critical assessment offers contemporary readers a firm grasp of what defines an avian migrant, how the organism came to be, what is known about its behavior, and how we can resolve its enduring mysteries. John H. Rappole's sophisticated survey of field data clarifies key ecological, biological, physiological, navigational, and evolutionary concerns. He begins with the very first migrants, who traded a home environment of greater stability for one of greater seasonality, and uses the structure of the annual cycle to examine the difference between migratory birds and their resident counterparts. He ultimately connects these differences to evolutionary milestones that have shaped a migrant lifestyle through natural selection. Rather than catalogue and describe various aspects of bird migration, Rappole considers how the avian migrant fits within a larger ecological frame, enabling a richer understanding of the phenomenon and its critical role in sustaining a hospitable and productive environment. Rappole concludes with a focus on population biology and conservation across time periods, considering the link between bird migration and the spread of disease among birds and humans, and the effects of global warming on migrant breeding ranges, reaction norms, and macroecology.

"Wieso sind Tiere keine Personen? Verändert sich die Persönlichkeit eines Menschen nach einer Herztransplantation? Kann man bei virtuellen Konstrukten im Internet von Personen reden? Wieso hat das individuelle Genom keinen Personenstatus? Diese und weitere Fragen stehen im Zentrum der Publikation. Vertreterinnen und Vertreter aus verschiedenen geisteswissenschaftlichen und naturwissenschaftlichen Disziplinen sowie Schriftsteller und Künstler kommen zu Wort. Der Titel ""Klon statt Person? Individualität im 21. Jahrhundert"" verweist in leicht provokanter Weise auf eine Herausforderung, der sich die Menschen zu Beginn des 21. Jahrhunderts zu stellen haben. Die Möglichkeit, Individuen zu klonen, stellt die Begriffe ""Person"" und ""Individualität"" grundsätzlich in Frage und bringt somit das abendländische Grundverständnis des Menschen ins Wanken."

Conservation of Tropical Birds has been written by four conservation biologists whose expertise spans all the tropical regions of the world. It is the first book to cover all the major issues in tropical bird conservation. Current problems faced by tropical bird conservationists are summarised and potential solutions outlined based on the results of case studies. Birds are key indicators of ecosystem health, and such a well-studied group of organisms, that they provide an excellent lens through which to examine global conservation problems caused by phenomena such as climate change, declines in ecosystem services, habitat loss, fires, overexploitation, and invasive species. Therefore, the book also provides an engaging synopsis of the general issues in conservation and the problems faced by other wildlife. This book serves as an important resource and companion to all people interested in observing and conserving birds in the tropics and elsewhere.
