Housing and Demographic Risk Factors Impacting Foot and Musculoskeletal Health in African Elephants [Loxodonta africana] and Asian Elephants [Elephas maximus] in North American Zoos

PLoS ONE, 2016
For more than three decades, foot and musculoskeletal conditions have been documented among both Asian [Elephas maximus] and African [Loxodonta africana] elephants in zoos. Although environmental factors have been hypothesized to play a contributing role

A review of current indicators of welfare in captive elephants (Loxodonta africana and Elephas maximus)

Animal Welfare, 2018
Concerns over elephant welfare in UK zoos have implications for their future in captivity. To monitor improvements made to elephant welfare in UK zoos, non-invasive, valid and reliable indicators of welfare are needed.

First report of changes in leukocyte morphology in response to inflammatory conditions in Asian and African elephants (Elephas maximus and Loxodonta africana)

PLoS ONE, 2017
Although the hematology of healthy elephants has been well-described, published information on hematological changes during disease is limited. The objective of this study was to describe qualitative morphological changes in the leukocytes of Asian and ...

Observations on the length of the intestinal tract of African Loxodonta africana (Blumenbach 1797) and Asian elephants Elephas maximus (Linné 1735) [PDF]

, 2018
The digestive tract of elephants is surprisingly short compared to other herbivorous mammals. However, measurements relating the length of the intestine to the body mass of the respective individual are rare.

Molecular characterization of adipose tissue in the African elephant (Loxodonta africana).

PLoS ONE, 2014
Adipose tissue (AT) is a dynamic and flexible organ with regulatory roles in physiological functions including metabolism, reproduction and inflammation; secreted adipokines, including leptin, and fatty acids facilitate many of these roles.

Fine-Scale Tracking of Ambient Temperature and Movement Reveals Shuttling Behavior of Elephants to Water

Frontiers in Ecology and Evolution, 2019
Movement strategies of animals have been well studied as a function of ecological drivers (e.g., forage selection and avoiding predation) rather than physiological requirements (e.g., thermoregulation). Thermal stress is a major concern for large mammals,

Reproductive Health Assessment of Female Elephants in North American Zoos and Association of Husbandry Practices with Reproductive Dysfunction in African Elephants (Loxodonta africana)

PLoS ONE, 2016
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 ...

The relationship of life stage to daily social patterns of captive African elephants (Loxodonta africana) and the correlation of handler perceptions of elephant personality to demonstrated social behaviors [PDF]

, 2017
Elephants typically have very strong social bonds, and social interactions can include affiliative, agonistic, or ambiguous behaviors. The social interactions and dominance hierarchy between individuals of a herd depend upon many factors, including ...

Odontoma in an African elephant (Loxodonta africana).

Journal of the South African Veterinary Association, 1990
The first known case of an odontoma in an African elephant (Loxodonta africana) is described. The tumour was fused with the coronal cementum of the sixth right mandibular molar tooth, thus preventing its eruption.
