African Elephant Sesquiterpenes

Journal of Natural Products, 1999
GC-MS analysis of extracts from temporal gland secretions of an African elephant has revealed the presence of several farnesol-related sesquiterpenes. Among these are (E)-2, 3-dihydrofarnesol (3), a bumblebee pheromone not seen before in mammals, and a rare component of a Greek tobacco, drimane-8alpha, 11-diol (4), never observed before in an animal.

Structure of African Elephant Populations

Journal of Heredity, 1995
The structure of elephant populations from east and south Africa has been analyzed by Georgiadis et al. (1994) on the basis of restriction site variation of mitochondrial DNA. They used F statistics based on identity by descent in tests for subdivision and reached the conclusion that there was a significant differentiation at the continental level, but

Blood Platelets of the African Elephant

Journal of Comparative Pathology, 2002
Platelet counts of 22 elephants varied between 229 x 10(9) and 622 x 10(9)/L. Light microscopy showed the platelets to be small, while electron microscopy revealed well preserved but activated platelets with some morphological differences from other mammalian platelets.

Sperm rescue in wild African elephants

Reproduction, Fertility and Development, 2015
This study investigated ways of improving the usefulness of ~1700 mL of poor-quality frozen semen collected from wild African elephant (Loxodonta africana) bulls. Ten semen samples from six bulls, frozen with 5% glycerol in Berliner cryomedium, with or without prior removal of the seminal plasma by centrifugation, were tested.
