Stereotypical behaviors are common in captive animals, particularly captive polar bears. Effects of oral administration of fluoxetine on chronic stereotypical and typical behaviors in a captive polar bear were monitored. Fluoxetine treatment terminated stereotypic pacing behavior, facial tic, and huffing/coughing activity. The expression of typical polar bear behaviors was not affected by fluoxetine treatment, although the proportion of time spent engaged in typical behaviors changed during the course of the observation period. Response of the bear to fluoxetine treatment indicated that pharmacologic manipulation of the serotonergic system can safely eliminate stereotypical behaviors in captive polar bears.

Coping behaviour is a response to aversive situations. Farm and laboratory animals kept in intensive housing systems use a set of strategies (escape, remove, search, wait) to cope with aversive situations. It is suggested that these strategies have been shaped by evolution as adaptations to fitness-threatening situations with which animals are confronted in their natural environment. In intensive housing systems, however, the animals often fail to change aversive situations by using these evolved coping strategies, and it is argued that abnormal behaviour can originate from unsuccessful coping behaviour. With respect to animal welfare, it is important to design housing systems that allow the animals to perform effective coping behaviour

Nature documentaries often depict animal life as a grim struggle for survival, but this visually stunning book opens our eyes to a different, more scientifically up-to-date way of looking at the animal kingdom. In more than one hundred thirty striking images, The Exultant Ark celebrates the full range of animal experience with dramatic portraits of animal pleasure ranging from the charismatic and familiar to the obscure and bizarre. These photographs, windows onto the inner lives of pleasure seekers, show two polar bears engaged in a bout of wrestling, hoary marmots taking time for a friendly chase, Japanese macaques enjoying a soak in a hot spring, a young bull elk sticking out his tongue to catch snowflakes, and many other rewarding moments. Biologist and best-selling author Jonathan Balcombe is our guide, interpreting the images within the scientific context of what is known about animal behavior. In the end, old attitudes fall away as we gain a heightened sense of animal individuality and of the pleasures that make life worth living for all sentient beings.

Return to the Sea portrays the life and evolutionary times of marine mammals-from giant whales and sea cows that originated 55 million years ago to the deep diving elephant seals and clam-eating walruses of modern times. This fascinating account of the origin of various marine mammal lineages, some extinct, others extant but threatened, is for the non-specialist. Set against a backdrop of geologic time, changing climates, and changing geography, evolution is the unifying principle that helps us to understand the present day diversity of marine mammals and their responses to environmental challenges. Annalisa Berta explains current controversies and explores patterns of change taking place today, such as shifting food webs and predator-prey relationships, habitat degradation, global warming, and the effects of humans on marine mammal communities.
