Grant Gazelle
The Grant's gazelles are a species complex or a superspecies consisting of three species. Originally, these were listed under the scientific species name Nanger granti (formerly Gazella granti ; the specific epithet refers to the British officer and researcher of the Nile springs James Augustus Grant (1827-1892 )). Molecular genetic investigations, however, revealed three monophyletic lines within the Grant's gazelles , with at least two of these lines showing no intermingling. For this reason, during a 2011 revision of the hornbeams by Colin Peter Groves and Peter Grubb , the group was split into three types:
- Southern Grant's Gazelle ( Nanger granti ( Brooke , 1872))
- Northern Grant's gazelle ( Nanger notatus ( Thomas , 1897))
- Eastern Grant's gazelle ( Nanger petersii ( Günther , 1884))
With a shoulder height of 82 cm and a body weight of 80 kg, the animals are large representatives of the gazelles . They occur in East Africa, their range extends from Tanzania , Kenya and Uganda northwards to Ethiopia and Somalia .
These gazelles are red-brown at the top and white on the underside. The outside of the white mirror is bounded by a vertical black stripe. A horizontal band runs along the side, although this is not very pronounced in adult animals. A white stripe extends from the eye to the nose, the horns are long and curled and, depending on the species, are closer or closer together. Thus contributing N. petersi relatively short, narrow horns that are almost straight, while the tips of the horns in some representatives of N. granti are directed downwards.
The choice of habitat is very diverse for the animals, they range from the scrub of the semi-deserts to the open tree savannah , but corridors with long grasses are avoided.
The deciduous and grass-eater live in herds of up to 30 animals, with a full-grown male leading the females and the offspring.
