Like other hartebeests, the bubal was a social animal. Luis del Mármol Carvajal wrote in 1573 that herds of 100 to 200 animals could be found in northern Morocco. According to 19th century writers, the bubal hartebeest preferred rocky areas with a fair amount of vegetation, in contrast to the sandy, drier habitat of the Addax.
A large antelope with a particularly elongated forehead and oddly shaped horns, the hartebeest stands just over 1 m (3 ft 3 in) at the shoulder, and has a typical head-and-body length of 200 to 250 cm (79 to 98 in). The weight ranges from 100 to 200 kg (220 to 440 lb). The tail, 40 to 60 cm (16 to 24 in) long, ends in a black tuft. [40]
The bluebuck and sable antelope diverged from each other 2.8 million years ago, while the roan antelope diverged from both of them 4.17 million years ago. Africa was going through climatic oscillations between 3.5 and 2 million years ago, and during a colder period, the ancestors of the sable antelope and bluebuck may have been separated, and ...
Bird extinction is the complete elimination of all species members under the taxonomic class, Aves. Out of all known bird species, (approximately 11,154), 159 (1.4%) have become extinct , with 226 (2%) being critically endangered . [ 1 ]
Many endemic organisms have very specific requirements for their survival that can only be found within a certain ecosystem, resulting in their extinction. Extinction may also take place very long after the destruction of habitat, a phenomenon known as extinction debt. Habitat destruction can also decrease the range of certain organism populations.
The event may put a species at risk of extinction or upset an ecosystem. [2] This is distinct from the mass die-off associated with short lived and synchronous emergent insect taxa which is a regular and non-catastrophic occurrence. [3] Causes of MME's include disease and human-related activities such as pollution.
A collaboration between Colossal Biosciences and conservationists plans to bring back the extinct dodo and reintroduce it to its once-native habitat in Mauritius.
Antilope is a genus of twisted-horn bovid that contains a single living species, the blackbuck of South Asia.Two extinct species are also known. [2]Many fossil antelopes were included in this genus, but have since been placed in new genera; for example the species formerly known as Antilope planicornis is now placed in its own genus, Nisidorcas.
