Loxodonta africana – African Elephant

Taxonomic notes: Preliminary genetic evidence suggests that there may be at least two species of African Elephant, namely the Savannah Elephant (Loxodonta africana) and the Forest Elephant (Loxodonta cyclotis) (Roca et al. 2001, 2005). A third species, the West African Elephant, has also been postulated. The IUCN SSC African Elephant Specialist Group currently accepts the single species proposa...

Continent-wide survey reveals massive decline in African savannah elephants

African elephants (Loxodonta africana) are imperiled by poaching and habitat loss. Despite global attention to the plight of elephants, their population sizes and trends are uncertain or unknown over much of Africa. To conserve this iconic species, conservationists need timely, accurate data on elephant populations. Here, we report the results of the Great Elephant Census (GEC), the first conti...

Low 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...

A histocytochemical study of mucus glycoproteins or mucins in the intestinal tract of the African elephant (Loxodonta africana).

The distribution of neutral mucins, sialomucins and sulphomucins was determined histochemically in the duodenum, jejunum, ileum and colon of the African elephant (Loxodonta africana). The techniques used were periodic acid-Schiff (PAS), alcian blue/periodic acid-Schiff (AB-PAS), high-iron-diamine/alcian blue (HID-AB), alcian blue at varying pH solutions and alcian blue at high temperature after...

Automatic Classification and Speaker Identification of African Elephant (<em>Loxodonta africana</em>) Vocalizations

Early primary--rather than primordial follicles constitute the main follicular reserve in the African elephant (Loxodonta africana).

Information on the ovarian follicle reserve in the African elephant (Loxodonta africana) is lacking. This study set out to determine the ratios of early preantral follicles and their relative dimensions in the ovaries of 16 African elephant aged 10-34 years. The ovaries were sectioned histologically. Follicles were counted and classified according to expansion of the pre-granulosa cells. Early ...
