Complete mitochondrial genome of Gazella subgutturosa reginae (Bovidae: Antilopinae).

ABSTRACT: In Qinghai province, Gazella subgutturosa reginae (Adlerberg, 1931) is only distributed in Qaidam basin and it is beneficial for the balance of this ecosystem. In this paper, we present the complete mitochondrial genome of Gazella subgutturosa reginae firstly, a circularized sequence with 16,435 bp, containing a total of 13 protein coding genes, 22 transfer RNA (tRNA) genes, and 2 ribosomal RNA (rRNA) genes. The sequence is similar to other subspecies of Gazella subgutturosa, the phylogenetic tree revealed that Gazella subgutturosa reginae and Gazella subgutturosa subgutturosa are more closely related to each other. Our research is useful for the taxonomic and evolutionary research of goitered gazelle.

Repeated hybridization of two closely related gazelle species (Gazella bennettii and Gazella subgutturosa) in central Iran.

Project description:Interspecific hybridization increasingly occurs in the course of anthropogenic actions, such as species translocations and introductions, and habitat modifications or occurs in sympatric species due to the shortage of conspecific mates. Compared with anthropogenically caused hybridization, natural hybridization is more difficult to prove, but both play an important role in conservation. In this study, we detected hybridization of two gazelle sister species, Gazella bennettii (adapted to dry areas) and Gazella subgutturosa (adapted to open plains), in five habitat areas, where G. bennettii naturally occur in central Iran. The hybrids have a nuclear genomic identity (based on two introns), habitat preference, and phenotype of G. bennettii, but the mitochondrial identity (based on cyt b) of G. subgutturosa. We suggest that natural hybridization of female G. subgutturosa and male G. bennettii happened twice in central Iran in prehistoric times, based on the haplotype pattern that we found. However, we found indications of recent hybridization between both species under special circumstances, for example, in breeding centers, due to translocations, or in areas of sympatry due to the shortage of conspecific mates. Therefore, these two species must be kept separately in the breeding centers, and introduction of one of them into the habitat of the other must be strictly avoided.

Identification and phylogenetic analysis of the complete mitochondrial genome of Fuzhong buffalo (Artiodactyla: Bovidae).

Project description:Fuzhong buffalo (Bubalus bubalis Linnaeus, 1758 breed Fuzhong, FB) is one of the famous indigenous breeds of buffalo in China. It is the first time that the complete mitochondrial genome sequence of the FB was reported. The total length of the mtDNA is 16,363 bp, It contains the typical structure, including 22 transfer RNA genes, two ribosomal RNA genes, 13 protein-coding genes and one non-coding control region (D-loop region). The overall composition of the mtDNA was estimated to be 32.98% for A, 26.34% for T, 26.70% for C and 13.98% for G. Phylogenetic analyses using N-J computational algorithms showed that the analyzed 19 ruminantia species are divided into four major clades: Bovidae, Cervidae, Giraffidae and Atilocapridae. In addition, our work confirmed that FB and Murrah buffalo (MB) have a close genetic relationship with fellow tribal members Nili-Ravi buffalo and Mediterranean buffalo. Meanwhile, we also found that FB and MB have a highly similar genetic relationship.

Identification and phylogenetic analysis of the complete mitochondrial genome of Mediterranean buffalo (Artiodactyla: Bovidae).

Project description:Mediterranean buffalo (Bubalus bubalis Linnaeus, 1758 breed Mediterranean, MEB) is one of the best milk-producing breeds in river-type buffaloes in the world. It is the first time that the complete mitochondrial genome sequence of the MEB was reported. The total length of the mtDNA is 16,357 bp, It contains the typical structure, including 22 transfer RNA genes, 2 ribosomal RNA genes, 13 protein-coding genes and 1 non-coding control region (D-loop region). The overall composition of the mtDNA was estimated to be 33.10% for A, 26.44% for T, 26.57% for C and 13.89% for G, in the order A > C > T > G feature occurs in the MEB. Phylogenetic analyses using N-J computational algorithms showed that the analyzed 18 ruminantia species are divided into four major clades: Bovidae, Cervidae, Giraffidae and Atilocapridae. In addition, our work confirmed that MEB and Nili-Ravi buffalo (NRB) have a close genetic relationship with fellow tribal members Murrah buffalo. Meanwhile, we also found that MEB and NRB have highly similar genetic relationship.

Diversification and subspecies patterning of the goitered gazelle (Gazella subgutturosa) in Iran.

Project description:Goitered gazelles, Gazella subgutturosa, exist in arid and semiarid regions of Asia from the Middle to the Far East. Although large populations were present over a vast area until recently, a decline of the population as a result of hunting, poaching, and habitat loss led to the IUCN classification of G. subgutturosa as "vulnerable." We examined genetic diversity, structure, and phylogeny of G. subgutturosa using mitochondrial cytochrome b sequences from 18 geographically distant populations in Iran. The median-joining network of cyt b haplotypes indicated that three clades of goitered gazelles can be distinguished: a Middle Eastern clade west of the Zagros Mountains (and connected to populations in Turkey and Iraq), a Central Iranian clade (with connection to Azerbaijan), and an Asiatic clade in northeastern Iran (with connection to Turkmenistan, Uzbekistan, and other Asian countries as far as northeastern China and Mongolia). Based on our results, we argue that Iran is the center of diversification of goitered gazelles, due to the presence of large mountain ranges and deserts that lead to the separation of populations. In accordance with previous morphological studies, we identified the Asiatic clade as the subspecies G. s. yarkandensis, and the other two clades as the nominate form G. s. subgutturosa. The new genetic information for goitered gazelles in Iran provides the basis for future national conservation programs of this species.

Conservation of the Goitered gazelle (Gazella subgutturosa) under climate changes in Iraq.

Project description:Climate is a vital factor that shapes habitat suitability for many species across space and time. Gazella subgutturosa (Goitered gazelle) is a globally vulnerable mammal already extinct in some areas of Armenia and Georgia and is highly threatened in other areas of its distribution. In this study, new data were gathered for 33 locations in north-eastern Iraq, and then together with literature data, Species Distribution Models (SDMs) were used to explore the geographical distribution of the gazelle under current and future climate change scenarios. We studied the relationship between seven climate variables and 43 occurrence records to predict habitat suitability of the gazelle under the current climate, and also under four future climate scenarios (RCP2.6 and RCP8.5 for both 2050 and 2080). Annual precipitation and isothermality had the most influence on the distribution of Gazella subgutturosa. The most suitable habitat in both the current and future scenarios was located in north-eastern Iraq close to the Iranian border near the Zagros Mountains. There was no difference in habitat suitability for the gazelle inside Iraqi Protected Areas (PAs) compared to outside the PAs. Using the occurrence records and IUCN Red List national assessments, we found Iraqi Goitered gazelle populations to be classified as Endangered (EN). Our results suggest urgent conservation planning is needed to save this species, including the establishment of new PAs. These results contribute new baseline information, which was currently missing Goitered gazelle in about Iraq, to the IUCN SSC Antelope Specialist Group, which will hopefully aid with future global assessments and conservation.

Complete mitochondrial genome of Saiga tatarica (Ruminantia; Pecora; Bovidae) isolate Wuwei in China.

Project description:This report described the complete mitochondrial genome of the Saiga antelope, Saiga tatarica, from the Gansu Endangered Animal Research Center (GEARC) in Gansu Province, China. The mitogenome was a circular molecule of 16,376 bps (Genbank accession number: MF497028). It contained 13 protein-coding, 22 tRNA and two rDNA genes. The protein-coding genes had ATA or ATG as the initiation codon, and were terminated by the typical stop codon TAA, except for NAD2 and NAD3. The complete mitogenome sequence would be useful for further understanding origination, evolution and conservation genetics of S. tatarica population in China.

Role of mass-kill hunting strategies in the extirpation of Persian gazelle (Gazella subgutturosa) in the northern Levant.

Project description:Continuous and intensive exploitation of wildlife resources by early agricultural societies had major ecological consequences in the ancient Near East. In particular, hunting strategies of post-Neolithic societies involving the mass killing of wild ungulates contributed to the eventual extirpation of a number of wild species. A remarkable deposit of bones of Persian gazelle (Gazella subgutarosa) from fourth millennium BCE levels at Tell Kuran in northeastern Syria provides insight into the unsustainable hunting practices that disrupted gazelle migratory patterns and helped set the course for the virtual extinction of this species and possibly other steppe species in the Levant. The social context of mass kills conducted during periods when people relied primarily on domestic livestock for animal resources sets them apart from the more targeted and sustainable practices of earlier periods, when wild animals were the major or sole source of animal protein.
