Abstract Identifying links between environmental, social, management, and health factors as they relate to physiological stress in captive elephants is crucial for the improvement of welfare and husbandry practices in North American zoos. Studies have examined the effects of short-term and chronic elevations in glucocorticoids in small groups of elephants, but few have examined adrenal activity on a large scale. This study evaluated 106 Asian (Elephas maximus) and 131 African (Loxodonta africana...

Abstract Relationships between animals and their human caretakers can have profound impacts on animal welfare in farms, laboratories and zoos, while human attitudes are important predictors of caretaker behavior towards livestock. In this study, we examined the impact of keeper attitudes about working with elephants on Keeper-Elephant Relationships (KERs) and Bonds (KEBs), and found evidence for reciprocity and welfare benefits to both parties. As part of a large, multi-institutional study of zo...

This study quantified social life events hypothesized to affect the welfare of zoo African and Asian elephants, focusing on animals that were part of a large multi-disciplinary, multi-institutional elephant welfare study in North America. Age was calculated based on recorded birth dates and an age-based account of life event data for each elephant was compiled. These event histories included facility transfers, births and deaths of offspring, and births and deaths of non-offspring herd mates. Ea...

The management of African (Loxodonta africana) and Asian (Elephas maximus) elephants in zoos involves a range of practices including feeding, exercise, training, and environmental enrichment. These practices are necessary to meet the elephants’ nutritional, healthcare, and husbandry needs. However, these practices are not standardized, resulting in likely variation among zoos as well as differences in the way they are applied to individual elephants within a zoo. To characterize elephant managem...

As part of a multi-institutional study of zoo elephant welfare, we evaluated female elephants managed by zoos accredited by the Association of Zoos and Aquariums and applied epidemiological methods to determine what factors in the zoo environment are associated with reproductive problems, including ovarian acyclicity and hyperprolactinemia. Bi-weekly blood samples were collected from 95 African (Loxodonta africana) and 75 Asian (Elephas maximus) (8–55 years of age) elephants over a 12-month peri...

Concerns about animal welfare increasingly shape people’s views about the acceptability of keeping animals for food production, biomedical research, and in zoos. The field of animal welfare science has developed over the past 50 years as a method of investigating these concerns via research that assesses how living in human-controlled environments influences the behavior, health and affective states of animals. Initially, animal welfare research focused on animals in agricultural settings, but t...

A breeding moratorium enacted in the early 1980s for African lions Panthera leo in North American zoos was lifted in 1998. However, post-moratorium reproduction was poorer than expected from 1999 to 2005. In 2007, therefore, a multi-institutional survey was conducted to provide a general overview of the Species Survival Plan® (SSP) African lion population ♀♀, and assess relationships between social, management, husbandry and environmental conditions, and reproductive activity. Females (n = 40) w...

Multi-institutional studies of welfare have proven to be valuable in zoos but are hampered by limited sample sizes and difficulty in evaluating more than just a few welfare indicators. To more clearly understand how interactions of husbandry factors influence the interrelationships among welfare outcomes, epidemiological approaches are needed as well as multifactorial assessments of welfare. Many questions have been raised about the housing and care of elephants in zoos and whether their environ...
