“…In order to investigate this phenomenon in more detail, Dorcas gazelles from Libya and Egypt should be included in future studies. Rebholz et al (1991) proposed that Saudi gazelles might be more distantly related to Dorcas gazelles than previously assumed (see also Rebholz and Harley 1999), but their analysis was partly based on samples from captive breeding groups, and it remains doubtful whether those samples were truly Saudi gazelles (Hammond et al 2001). While probably extinct in the wild, presumed Saudi gazelles held in captivity appear to be the product of repeated hybridization with other gazelle taxa such as chinkara (G. bennetti) and Goitered gazelle (G. subgutturosa; Rebholz and Harley 1997;Hammond et al 2001).…”

A phylogeographic framework for the conservation of Saharan and Arabian Dorcas gazelles (Artiodactyla: Bovidae)

Many species of gazelles (Gazella spp.) are nowadays threatened by hunting, poaching, habitat loss and habitat deterioration. Conservation efforts for this group not only face the problem of maintaining remnant populations, but often natural populations have been extirpated from the wild. In some cases, though, captive breeding programs exist that might provide a valuable source for future reintroductions. A major problem in this context is that phylogeographic relationships among different (potentially locally adapted) populations, and even basic phylogenetic relationships between species, are poorly understood, thus hampering the assignment of management units, breeding groups or stocks for reintroduction projects. Our present study focused on Dorcas gazelles (G. dorcas and G. saudiya) from the species' entire distribution range, with samples originating from western Saharan Africa into Saudi Arabia. In stark contrast to previous studies reporting on pronounced genetic structure in taxa such as Mountain gazelles (G. gazella), we detected low genetic diversity and no evidence for major phylogenetic lineages when analyzing two mitochondrial genetic markers. Using a coalescent approach we infer a steep population decline that started approximately 25,000 years before present and is still ongoing, which coincides with human activities in Saharan Africa. Our phylogenetic analyses, statistical parsimony network analysis and inferred colonization patterns shed doubt on the validity of various described subspecies of G. dorcas.

“…Sequences from other gazelle taxa were obtained from GenBank (7 sequences, Rebholz and Harley 1999;Hassanin and Douzery 1999;Hammond et al 2001), the Estación Experimental de Zonas Á ridas in Almeria, Spain (G. cuvieri), Wadi al-Safa Wildlife Centre, UAE (G. bennetti), Prince Ahmed bin Abdulaziz Farm, Saudi Arabia (G. leptoceros loderi; reported to originate from Tunisia), or from the wild (G. leptoceros leptoceros: Hatiyat Umm Ghuzlan, western Egypt; G. cuvieri: Chambi N.P., Tunisia).

Phylogenetic analysis of mitochondrial DNA sequences reveals polyphyly in the goitred gazelle (Gazella subgutturosa)

et al. 2010

Goitred gazelle (Gazella subgutturosa) rank among the most endangered mammals on the Arabian Peninsula and the Asian steppes. Past conservation efforts have been plagued by confusion about the phylogenetic relationship among various-phenotypically discernablepopulations, and even the question of species boundaries was far from being certain. This lack of knowledge had a direct impact on conservation measures, especially ex situ breeding programmes, hampering the assignment of captive stocks to potential conservation units. Here, we provide a phylogenetic framework, based on the analysis of mtDNA sequences of a number of individuals collected from the wild and captivity throughout the species' natural range. Our analyses revealed a polyphyly within the presumed species of G. subgutturosa resulting in two distinct clades: one on the Arabian Peninsula, Iraq, Jordan, Syria and Turkey (Gazella marica; sand gazelle) and one genetically diverse larger clade from the rest of its Asian range (G. subgutturosa; goitred gazelle). Additionally, we provide a quick method (PCR-RFLP) to analyse the taxonomic affiliation of captive gazelles that will be used for re-introductions into the wild.

“…The three species Dama gazelle (Nanger dama), Soemmerring's gazelle (N. soemmerringii) and Grant's gazelle (N. granti) belonged to Gazella until recently, when Nanger was restored to full genus status (Groves 2000). The Nanger species share nine unique centric fusions and are genetically distinct (Vassart et al 1995;Rebholz and Harley 1999) and have a highly derived character state of large and voluminous ridges on the posterior basicranium (Grubb 2005).…”

Three reciprocally monophyletic mtDNA lineages elucidate the taxonomic status of Grant’s gazelles

2007

The intraspecific phylogeography of Grant's gazelles Nanger granti was assessed with mitochondrial DNA control region sequences. Samples of 177 individuals from 17 Kenyan and Tanzanian populations were analysed. Three highly divergent, reciprocally monophyletic lineages were found, with among group net nucleotide distances of 8-12%. The three lineages-notata, granti and petersiigrouped populations according to their geographic origin, encompassing populations in the north, southwest, and east, respectively. The mtDNA lineages reflected distinct evolutionary trajectories, and the data are discussed in reference to the four currently recognised subspecies. We suggest Grant's gazelles be raised to the superspecies Nanger (granti) comprising three taxonomic units corresponding to the three mtDNA lineages. There was no evidence of gene flow between the notata and granti lineages, despite their geographic proximity, suggesting reproductive isolation. These constitute evolutionary significant units within the adaptive evolutionary framework. Due to its restricted geographic distribution and genetic and morphological distinctiveness, we suggest the petersii lineage be raised to the species Nanger (granti) petersii within the Grant's gazelles superspecies.
