The monitoring of endocrine markers that inform about an animal's physiological state has
become an invaluable tool for studying the behavioral ecology of primates. While the …

While non-human primate studies have long been conducted in laboratories, and more
recently at zoological parks, sanctuaries are increasingly considered a viable setting for …

Abstract Artificial Light At Night (ALAN) is an emerging pollution, that dramatically keeps on

Emotion is one of the central topics in animal studies and is likely to attract attention
substantially in the coming years. Recent studies have developed a thermo-imaging …

Cortisol is often measured as a marker for stress. Therefore, a profound validation of the time-
lag between the stressor and the increase and peak in cortisol levels is needed. No study …

During the past three decades, non-invasive methods for assessing physiological, in
particular endocrine, status have revolutionized almost all areas of primatology, including …

In addition to behavioral evaluations, stress assessments are also important for measuring
animal welfare. Assessments of long-term stress are particularly important given that …

Research on age-related changes in morphology, social behavior, and cognition suggests
that the development of bonobos (Pan paniscus) is delayed in comparison to chimpanzees …

Understanding the factors associated with the long-term stress levels of captive animals is
important from the view of animal welfare. In this study, we investigated the effects of …

Monitoring concentrations of stress hormones is an important tool for behavioral research
and conservation for animals both in the wild and captivity. Glucocorticoids can be …
