Thomson's gazelles are dependent on short grass. [18] Their numbers can be highly concentrated at the beginning of the rains when the grass grows quickly. [18] In the Serengeti, they follow the larger herbivores, such as plains zebras and blue wildebeests as they mow down the taller grasses. [18] In the wild, Thomson's gazelles can live 10–15 ...
The Grant's gazelle looks similar to a Thomson's gazelle, except it is much larger and has lyre-shaped horns which are stout at the base, clearly ringed, and measuring 45–81 cm (18–32 in) long. A useful field mark is the white on the rump that extends over the top of the tail in Grant's but not Thomson's gazelles.
Arabian gazelles are selective browsers, preferring woody plants over grasses.They predominantly feed on all fours, but may rear up on their hind legs to access higher food. [5] They share their habitat with many other herbivores, including Dorcas gazelles ( Gazella dorcas ), mountain gazelles ( Gazella gazella ), Nubian ibex ( Capra nubiana ...
Hunting is now banned in the United Arab Emirates, but feral goats and donkeys are plentiful and graze indiscriminately, lessening the chance for the native gazelles to recover from their reduced population sizes. Large terrestrial mammals still found in the United Arab Emirates include the Arabian tahr, the Arabian oryx and the sand gazelle. [14]
Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
The gerenuk [a] (Litocranius walleri), also known as the giraffe gazelle, is a long-necked, medium-sized antelope found in parts of East Africa. The sole member of the genus Litocranius , the gerenuk was first described by the naturalist Victor Brooke in 1879.
The dorcas gazelle (Gazella dorcas), also known as the ariel gazelle, is a small and common gazelle.The dorcas gazelle stands about 55–65 cm (1.8–2.1 feet) at the shoulder, with a head and body length of 90–110 cm (3–3.5 feet) and a weight of 15–20 kg (33–44 pounds).
Until recently, the sand gazelle was considered a subspecies of the goitered gazelle (Gazella subgutturosa), as Gazella subgutturosa marica.A 2010 genetic study established that it was a distinct lineage, [2] and it is now considered a separate species. [1]
