Birth statistics for African (Loxodonta africana) and Asian (Elephas maximus) elephants in human care: history and implications for elephant welfare.
African (Loxodonta africana) and Asian elephants (Elephas maximus) have lived in the care of humans for many years, yet there is no consensus concerning some basic parameters describing their newborn calves. This study provides a broad empirical basis for generalizations about the birth heights, birth weights, birth times and gestation periods of elephant calves born in captivity. I obtained da...
متن کاملLow coverage sequencing of two Asian elephant (Elephas maximus) genomes
BACKGROUND There are three species of elephant that exist, the Asian elephant (Elephas maximus) and two species of African elephant (Loxodonta africana and Loxodonta cyclotis). The populations of all three species are dwindling, and are under threat due to factors, such as habitat destruction and ivory hunting. The species differ in many respects, including in their morphology and response to d...
متن کاملFirst report of changes in leukocyte morphology in response to inflammatory conditions in Asian and African elephants (Elephas maximus and Loxodonta africana)
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 African elephants (Elephas maximus and Loxodonta africana) diagnosed with a variety of inflammatory conditions. Twenty-five of 27 elephants had ...
متن کاملAssessment of Body Condition in African (Loxodonta africana) and Asian (Elephas maximus) Elephants in North American Zoos and Management Practices Associated with High Body Condition Scores
Obesity has a negative effect on health and welfare of many species, and has been speculated to be a problem for zoo elephants. To address this concern, we assessed the body condition of 240 elephants housed in North American zoos based on a set of standardized photographs using a 5-point Body Condition Score index (1 = thinnest; 5 = fattest). A multi-variable regression analysis was then used ...
متن کاملElephants: Nutrition and Dietary Husbandry
Elephants are the largest extant herbivores on earth. Although the average weight of adult Asian elephants (Elephas maximus) tends to be less than that of adult African elephants (Loxodonta africana), in the wild their weight ranges overlap (Asian, 1,800-5,000 kg [4,000-11,000 lb]; African, 1,800-6,000 kg [4,000-13,000 lb]) and are influenced by age, sex, health, and food supply. Their nutrient...
