“…The results of microsatellite polymorphism revealed relatively high degree of heterozygosity in the Turkish donkey populations investigated in this study. Among Turkish donkey populations, the H E ranged from 0.6294 (ISP) to 0.6983 (ANT), which showed a comparable level to the previous values reported in Spanish donkeys [ 36 ], Catalonian donkey breeds [ 37 ], Croatian coast donkey populations [ 48 ], Balkan donkey breeds [ 35 ], Tunisian donkeys [ 43 ], Chinese donkey breeds [ 39 , 40 , 41 , 42 ] and was more diversified than Italian [ 44 , 45 , 46 , 47 ] and American donkeys [ 49 ]. This finding indicates that there are appreciable differences in the level of genetic variability among 16 Turkish donkey populations.…”

“…Neighbor-net representing the Reynolds distance confirmed these findings; Cluster II (KUT – ISP) and Cluster II (AYD – KAH) groups clustered in an intermediate position between the Cluster I (CAT, KIR, MAR, KAR, SAN) and Cluster IV (MER, MUG, KON, ANT, KAS, MAL, TOK). The F ST value of Turkish donkey populations detected in this study was similar to the value of American donkeys [ 49 ], Chinese donkeys [ 42 ], but lower than that of donkeys in the Europe [ 45 , 46 ], Near East and northeast Africa [ 53 ].…”

This study presents the first insights to the genetic diversity and structure of the Turkish donkey populations. The primary objectives were to detect the main structural features of Turkish donkeys by microsatellite markers. A panel of 17 microsatellite markers was applied for genotyping 314 donkeys from 16 locations of Turkey. One hundred and forty-two alleles were identified and the number of alleles per locus ranged from 4 to 12. The highest number of alleles was observed in AHT05 (12) and the lowest in ASB02 and HTG06 (4), while ASB17 was monomorphic. The mean HO in the Turkish donkey was estimated to be 0.677, while mean HE was 0.675. The polymorphic information content (PIC) was calculated for each locus and ranged from 0.36 (locus ASB02) to 0.98 (locus AHT05), which has the highest number of alleles per locus in the present study. The average PIC in our populations was 0.696. The average coefficient of gene differentiation (GST) over the 17 loci was 0.020 ± 0.037 (p < 0.01). The GST values for single loci ranged from −0.004 for LEX54 to 0.162 for COR082. Nei’s gene diversity index (Ht) for loci ranged from 0.445 (ASB02) to 0.890 (AHT05), with an average of 0.696. A Bayesian clustering method, the Structure software, was used for clustering algorithms of multi-locus genotypes to identify the population structure and the pattern of admixture within the populations. When the number of ancestral populations varied from K = 1 to 20, the largest change in the log of the likelihood function (ΔK) was when K = 2. The results for K = 2 indicate a clear separation between Clade I (KIR, CAT, KAR, MAR, SAN) and Clade II (MAL, MER, TOK, KAS, KUT, KON, ISP, ANT, MUG, AYD and KAH) populations.

“…Although in this study we used genetic profiles at the nuclear DNA level of only seven adult Banat donkey females, all the parameters of genetic diversity calculated for this group were similar or even higher compared to those observed in the two larger sub-populations of Balkan donkey females (Table 4), and also in populations of other donkey breeds distributed worldwide (Jordana, Folch & Sanchezm, 1999;Jordana et al, 2016;Aranguren-Mendez, Jordana & Gomez, 2001;Ivankovic et al, 2002;Blasi et al, 2005;Ciampolini et al, 2007;Zhu et al, 2013;Matassino et al, 2014;Rosenbom et al, 2015). Furthermore, two private alleles were observed in Banat donkeys characterized also by the significant excess of heterozygotes.…”

“…Furthermore, the extant maternal landscape of the Spanish Catalana, Mallorqina and Zamorano-Leonessa breeds is highly similar to that which can be observed in the two African donkey populations, one from Morocco and the other from Zimbabwe (Aranguren-Mendez et al, 2004). On the other hand, Spanish donkey breeds, such as for instance the Catalonian donkey, have been commonly used in the past few centuries to improve not only European but also American breeds (Jordana & Folch, 1996;Jordana et al, 2016). To the authors' best knowledge, the genetic impact of Spanish donkeys on those from the Balkan Peninsula has not been recorded, but it is possible, since, according to local breeders from Serbia, in the XVIII century the Habsburg queen Maria Theresa requested that a heard of Spanish donkeys be transferred to the north-eastern part of Serbia, the Banat region, to work in local vineyards.…”

The dominant donkey breed in the Balkans is the mid-sized Balkan donkey with a grey to chocolate coat color. Local breeders from Serbia, however, still maintain a few larger individuals of a lighter coat color, named Banat donkey, and speculate that they are descendants of a Spanish donkey heard that had been transferred to the Banat region by the Hapsburg Queen Maria Theresa in the XVIII century for a specific purpose, to work in local vineyards. We have previously found a unique nuclear gene-pool and a prevalence of mitochondrial Clade 2 haplotypes in several such animals. In this study, we: (i) perform a comparative analysis of 18 morphological traits of the Banat donkey (seven individuals), Balkan donkey (53 individuals from two sub-populations of this breed) and the potential hybrids (eight individuals), and demonstrate the morphological distinctiveness of the Banat donkey, highlighting the diagnostic traits for distinguishing the breed: hip height, croup width, body length and chest depth; (ii) reanalyse published nuclear microsatellite data for these groups, and reveal that, although severely depopulated, the genetically distinct Banat donkey is not severely affected by the loss of genetic diversity and inbreeding; (iii) demonstrate that previously published Banat donkey mitochondrial haplotypes, analyzed genealogically together with those reported in ancient and modern individuals from Spain, Italy, Turkey, Cyprus and Africa, are shared with three Spanish breeds and individuals belonging to Amiata and some other Italian breeds. A unique morphological feature present in Banat and Somali wild donkeys, but also in Amiata donkeys, black stripes on legs, suggests that the origin of Clade 2 donkeys may be much more complex than previously thought. Actions to preserve the Banat donkey, a valuable but critically endangered genetic resource (<100 individuals), are urgent.

“…Equine biodiversity was also considered within the scope of the CONBIAND network. The fingerprint of Iberian breeds on modern creole American breeds was studied in horses by the BIOHORSE (Latin American Horse Biodiversity Project) consortium [99] and in donkeys by the BIODONKEY (Latin American Donkey Biodiversity Project) consortium [100]. The latter consortium also studied breed contributions to the general biodiversity of the donkey species, outlining some geo-evolutionary conclusions [101].…”

Creating national committees for domestic animal genetic resources within genetic resource national commissions is recommended to organize in situ and ex situ conservation initiatives. In situ conservation is a high priority because it retains traditional zootechnical contexts and locations to ensure the long-term survival of breeds. In situ actions can be based on subsidies, technical support, structure creation, or trademark definition. Provisional or permanent relocation of breeds may prevent immediate extinction when catastrophes, epizootics, or social conflicts compromise in situ conservation. Ex situ in vivo (animal preservation in rescue or quarantine centers) and in vitro methods (germplasm, tissues/cells, DNA/genes storage) are also potential options. Alert systems must detect emergencies and summon the national committee to implement appropriate procedures. Ex situ coordinated centers must be prepared to permanently or provisionally receive extremely endangered collections. National germplasm banks must maintain sufficient samples of national breeds (duplicated) in their collections to restore extinct populations at levels that guarantee the survival of biodiversity. A conservation management survey, describing national and international governmental and non-governmental structures, was developed. Conservation research initiatives for international domestic animal genetic resources from consortia centralize the efforts of studies on molecular, genomic or geo-evolutionary breed characterization, breed distinction, and functional gene identification. Several consortia also consider ex situ conservation relying on socioeconomic or cultural aspects. The CONBIAND network (Conservation for the Biodiversity of Local Domestic Animals for Sustainable Rural Development) exemplifies conservation efficiency maximization in a low-funding setting, integrating several Latin American consortia with international cooperation where limited human, material, and economic resources are available.
