| Contributor(s):: Tithipong Plangsangmas, Janine L. Brown, Chatchote Thitaram, Ayona Silva-Fletcher, Katie L. Edwards, Veerasak Punyapornwithaya, Patcharapa Towiboon, Chaleamchat Somgird
Salivary immunoglobulin A (sIgA) has been proposed as a potential indicator of welfare for various species, including Asian elephants, and may be related to adrenal cortisol responses. This study aimed to distinguish circadian rhythm effects on sIgA in male and female Asian elephants and...
Evaluating the Reliability of Non-Specialist Observers in the Behavioural Assessment of Semi-Captive Asian Elephant Welfare
| Contributor(s):: Jonathan L. Webb, Jennie A. H. Crawley, Martin W. Seltmann, Océane Liehrmann, Nicola Hemmings, U Kyaw Nyein, Htoo Htoo Aung, Win Htut, Virpi Lummaa, Mirkka Lahdenperä
Recognising stress is an important component in maintaining the welfare of captive animal populations, and behavioural observation provides a rapid and non-invasive method to do this. Despite substantial testing in zoo elephants, there has been relatively little interest in the application of...
Elephants in Nepal: Correlating disease, tourism, and welfare
| Contributor(s):: Szydlowski, Michelle
Asian elephants and humans have long shared their lives, but recent changes in human perspectives on animal use have created ripples through the small country of Nepal. Captive elephants are caught in the crossfire between local communities, elephant owners, mahouts, and NGOs in debates over...
Behavioral characterization of musth in Asian elephants (Elephas maximus): Defining progressive stages of male sexual behavior in in-situ and ex-situ populations
| Contributor(s):: LaDue, Chase A., Vandercone, Rajnish P. G., Kiso, Wendy K., Freeman, Elizabeth W.
Complementary studies of wild and zoo-housed animals offer insight into behavioral variation across a range of conditions including the context under which various behaviors evolved in natural settings. This information can be used to improve the sustainability of in-situ and ex-situ populations...
The Behavioral Effects of Feeding Enrichment on a Zoo-Housed Herd of African Elephants (Loxodonta africana)
| Contributor(s):: Caroline Marie Driscoll
A comprehensive study on the behavioral effects of feeding enrichment was conducted on six African elephants housed at the North Carolina Zoological Park in Asheboro, NC. The herd is comprised of are two adult males, three adult females, and one subadult female. The study was conducted over a...
Barriers to Sustainable Hunting-Based Conservation of Elephants in Zimbabwe
| Contributor(s):: Jessica Cusworth
The international demand for ivory has devastated African elephant populations. In 2015, more elephants were poached for ivory than were born. Many countries have sought to decrease poaching pressures through ivory trade bans. However, Zimbabwe, home to the second largest African elephant...
A Case Study: Observations of Behaviors & Vocalizations in a Captive Asian Elephant (Elephas maximus) During Quarantine
| Contributor(s):: Alexandra Dilley
Bozie, an Asian elephant (Elephas maximus), was relocated from the Baton Rouge Zoo to Smithsonian’s National Zoo. During a requisite 29-day quarantine period, I recorded Bozie’s stress-related behaviors and the vocalizations she produced when she was alone and with her keepers in...
Contagious Yawning in African Elephants (Loxodonta africana): Responses to Other Elephants and Familiar Humans
| Contributor(s):: Zoë T. Rossman, Clare Padfield, Debbie Young, Benjamin L. Hart, Lynette A. Hart
While spontaneous yawning is common across all vertebrate classes, contagious yawning is less common and has been observed only in a few species of social animals. Interspecific contagious yawning in response to yawning by humans has been observed only by chimpanzees and dogs. After...

Social Interactions in Zoo-Housed Elephants: Factors Affecting Social Relationships
| Contributor(s):: Ellen Williams, Anne Carter, Carol Hall, Samantha Bremner-Harrison
Elephants have complex social systems that are predominantly driven by ecological factors in situ. Within zoos, elephants are held in relatively static social groups and the factors observed driving social relationships in the wild are largely absent. Little research has investigated the effect...
Ecophysiology to understand elephants' crop raiding behavior.
| Contributor(s):: Steve Ngama, C. Vermeulen, J. Bindelle
Conservation science has emerged to stem the current loss of biodiversity. To be efficient in this goal it needs integrative disciplines like ecophysiology, a biological field that studies the adaptation of an organism's physiology to environmental conditions. Surprisingly few...

Scientific and Ethical Issues in Exporting Welfare Findings to Different Animal Subpopulations: The Case of Semi-Captive Elephants Involved in Animal-Visitor Interactions (AVI) in South Africa
| Contributor(s):: Barbara de Mori, Elena Stagni, Linda Ferrante, Gregory Vogt, Keith A. Ramsay, Simona Normando
Elephants are charismatic, cognitively highly-developed animals, whose management conditions can vary along a “wild–captive continuum.” Several protocols have been proposed for the assessment of zoo elephants’ welfare. It is important to investigate the possible...
