Northern Bushbuck

The harnessed bushbuck (Tragelaphus scriptus) or northern bushbuck, is a medium-sized antelope, widespread in sub-Saharan-Africa. The harnessed bushbuck species has been separated from the Cape bushbuck, a southern and eastern species. == Taxonomy == In a 2007 study, 19 genetically-based groupings were found, some of which do not correspond to previously described subspecies; eight of these were grouped under the nominate taxon. Former subspecies included as synonyms to the nominate taxon are phaleratus, bor and dodingae. Hassanin et al. (2018) found an mtDNA/nuclear DNA discordance between scriptus and sylvaticus clades. Their phylogenetic analyses showed that the scriptus (northern) lineage is a sister-group of sylvaticus (southern) lineage in the nuclear tree, whereas it has nyala (Tragelaphus angasii) haplotypes in the mitochondrial tree. They also found different karyotypes (chromosome numbers and arrangements), with those of scriptus deriving from the nyala. They concluded that scriptus (but not sylvaticus) had hybridized with an "extinct species closely related to T. angasii" in ancient times; and that "the division into two bushbuck species is supported by the analyses of nuclear markers and by the karyotype...". As the first of the bushbucks to be described by Pallas in 1766 as Antilope scripta from Senegal, it retains the…
