In the wake of telling critiques of the foundations on which earlier conclusions were based, the last 15 years have witnessed a renaissance in the study of social learning in apes. As a result, we are able to review 31 experimental studies from this period in which social learning in chimpanzees, gorillas, and orangutans has been investigated. The principal question framed at the beginning of this era, Do apes ape? has been answered in the affirmative, at least in certain conditions. The more interesting question now is, thus, How do apes ape? Answering this question has engendered richer taxonomies of the range of social-learning processes at work and new methodologies to uncover them. Together, these studies suggest that apes ape by employing a portfolio of alternative social-learning processes in flexibly adaptive ways, in conjunction with nonsocial learning. We conclude by sketching the kind of decision tree that appears to underlie the deployment of these alternatives.

Canids form a large part of Indigenous Australian life and mythology, an association first developed with the dingo, and later with the domestic dog. The relationship between canids and Indigenous Australians is intricate, but unique in that these peoples never domesticated the wild dingo. Neither were dingoes and dogs seen as a source of food nor in many cases considered practical hunting assistants, yet they were highly prized. Apart from featuring heavily in Indigenous Australian spirituality (The Dreaming), advantages of camp dingoes and dogs include them being protectors or guardians, "bed warmers," and companions. However, these benefits were weighed against the many associated social and economic costs incurred such as disruption to camp life and religious ceremony, burden on camp food supply and storage, and potential source of disease. This review explores the relationship between Indigenous Australians, dingoes and dogs, and attempts to explain why dingoes, and later dogs, were kept, yet not domesticated. By bringing together the many disparate observations made by early anthropologists, insight into traditional human-canid relationships may be gleaned.

The idea of animals possessing personalities was once dismissed by the scientific community, but has since gained traction with evidence for potential application to improve captive animal management and welfare. Although domestic cats are popular companion animals, research has tended to overlook the value of personality assessment for management and care of pet cats. The aim of this study was to investigate personality in a large sample of pet cats with a view to understanding practical implications for pet cats in the home. Personality of 2,802 pet cats, from South Australia and New Zealand, was rated by their owners utilising a survey measuring 52 personality traits. Five reliable personality factors were found using principal axis factor analysis: Neuroticism, Extraversion, Dominance, Impulsiveness and Agreeableness. Implications for the ‘Feline Five’ are discussed in relation to their potential application to improving the management and welfare of pet cats. Highly Impulsive cats for example, may be reacting to something stressful in their environment, whereas cats with low Agreeableness scores, showing irritability may indicate underlying pain or illness. Thus, the need for a systematic and holistic approach to personality that includes both the individual pet cat and its environment is recommended, and opens the door to future interdisciplinary intervention.
