Sexual Segregation in Vertebrates
Males and females often differ in developmental patterns, adult morphology, ecology and behaviour, and in many mammals males are often larger. Size dimorphism results in divergent nutritional and energetic requirements or reproductive strategies by the sexes, which in turn sometimes causes them to select different forage, use different habitats, and express differing social affinities. Such divergent life-styles often lead males and females to live large parts of their lives separately. Sexual segregation is widespread in animals. Males and females may share the same habitat, but at different times, for example, or they might use different habitats entirely. Why did sexual segregation evolve and what factors contribute to it? Sexual Segregation in Vertebrates explores these questions by looking at a wide range of vertebrates and is aimed as a synthesis of our current understanding and a guide for future research.
Sexual Segregation in Vertebrates
Males and females of many species can, and do, live separately for long periods of time. This sexual segregation is widespread and can be on social, spatial or habitat scales. An understanding of sexual segregation is important in the explanation of life history and social preference, population dynamics and the conservation of rare species. Sexual Segregation in Vertebrates explores the reasons why this behaviour has evolved and what factors contribute to it.
Assessing the Environmental Adaptation of Wildlife and Production Animals
Wild animals under human care as well as domesticated farm production animals are often exposed to environmental changes (e.g., capture and transportation). Short-term or acute changes in physiological indices (e.g., heart rate, respiration, body temperatures, immune cells, and stress hormonal biomarkers) provide crucial information regarding the responses of animals to novel environments, and they could provide crucial determining factors for the long-term health and welfare of animals. This Special Issue includes experimental research papers that demonstrate the applications of physiological indices and welfare assessment methods (e.g., morphological and morphometric data, behavioural assessments, thermal profiles, and physiological markers) in any wildlife or production animal (e.g., rescued and rehabilitating animals, pets, competition animals, farm animals, and zoo animals), in response to environmental and management related factors. The goal is to provide examples of new research and techniques that can be used to monitor short- and long-term environmental adaptation of animals under human care.
Darwinian Sociocultural Evolution
Addresses today's major dilemmas in social scientific theory from the modern Darwinian sociocultural evolutionary approach.
Mountain Spirit
Drawing on extensive ethnographic work among descendant native peoples and ongoing archaeological excavations, Mountain Spirit shows that many groups have visited or lived in the area in prehistoric and historic times. Primary among them was the Shoshone group called Tukudika, or Sheep Eaters, who maintained a rich and abundant way of life closely related to their primary source of protein, the mountain sheep of the high-altitude Yellowstone area.

Ökologie der Wirbeltiere
Das erste Lehrbuch zur Ökologie der Wirbeltiere Der Wolf frisst einen Elch, der Luchs ein Reh und der Habicht einen jungen Waldkauz. Was bedeutet das für die Bestände der Beutetiere? Vögel und Säugetiere zeigen als endotherme Wirbeltiere viele Gemeinsamkeiten in ihrer Biologie. Ausgehend von den theoretischen Grundlagen der Ökologie und mit einem konsequent evolutionsbiologischen Ansatz behandelt «Ökologie der Wirbeltiere» die Ernährung unter ökophysiologischen und verhaltensökologischen Aspekten, die Fortpflanzung, die räumliche Ökologie auf allen Skalenebenen, Wanderungen, die Populationsbiologie sowie die Interaktionen zwischen Arten, nämlich Konkurrenz, Prädation und Parasiten, und schließt mit einem Kapitel zur Naturschutzbiologie. Die theoretischen Grundlagen sind stets mit den aktuellen empirischen Befunden verknüpft; diesen wird ein großes Gewicht beigemessen.
