“…[55] [56] In spite of the correlation obtained for the EO composition with some bioclimatic and edaphic factors and the variance explained by the environmental factors, the effect of genetic factors should not be neglected since the biosynthesis of secondary metabolites could be regulated by both genetic and environmental factors simultaneously. [57][58] The outcrossing breeding system and the high genetic diversity of O. compactum [59] [60] could also contribute to the high chemical diversity detected within populations.…”

The present study aimed to evaluate the influence of environmental factors on essential oils (EOs) composition of Origanum compactum populations sampled all over the distribution area of the species in Morocco, and to determine the extent of the chemical profiles throughout the geographical distribution of the species. The chemical compositions were submitted to canonical correlation analysis and canonical discriminant analysis that indicated a significant relationship between oil components and some environmental factors. According to their chemical composition and edapho-climatic characteristics, two major groups of populations were differentiated. The first group was composed of samples growing in regions with humid climate, clayey, sandy, and alkaline soils. These samples showed high thymol, α-terpineol, linalool, and carvacryl methyl oxide content. The second group consisted of plants belonging to semi-arid climate, and growing at high altitudes and silty soils. These samples were characterized by high carvacrol, α-thujene, α-terpinene, and myrcene content. However, populations exposed to sub-humid climate, appeared less homogeneous and belong mainly either to the first or second group. A significant correlation between some edaphic factors (pH, K O content, soil texture) and the EOs yield of O. compactum plants was evidenced. In spite of the correlation obtained for the oil composition with edapho-climatic factors and the variance explained by the environmental data set, the observed EO diversity might be also genetically determined.

“…Microsatellites are molecular markers with a high degree of polymorphism, good stability and wide availability in mammals. They are useful molecular markers in the field of population genetic analysis and have been widely used in genetic protection of wildlife [12,23,[30][31][32][33]. In the analysis of microsatellite data, the number of microsatellite loci (A), the heterozygosity (H E ), and polymorphic information content (PIC) are the important indicators of the level of diversity.…”

“…Microsatellite DNA, also known as simple sequence repeats (SSRs) or short tandem repeats (STRs), consists of 1-6 core sequences repeated in series. With good stability, wide distribution, dominant inheritance, and many other advantages, SSRs provide excellent markers for measuring genetic diversity [10,11] and looking for markers of valuable traits in a species such as the forest musk deer [12][13][14][15][16]. Microsatellites are also useful for determining the potential for hybridization [17,18], for quantitative trait locus (QTL) mapping and trait linkage analysis [19,20], and as the basis for molecular marker selection in animal breeding.…”

We investigated the genetic diversity of the population of captive forest musk deer (Moschus berezovskii) in Barkam Musk Deer Breeding Centre using twelve microsatellite markers, and then analyzed the change in genetic structure of successive generation groups from the population. The data provide a new understanding for the evaluation and usage of the breeding management system. Microsatellite marker analysis detected 141 alleles with an average of 11.75 alleles for each marker. The average expected heterozygosity (HE) was 0.731. Performing an F-statistical analysis on the data showed that the genetic diversity of population decreased, and the inbreeding coefficient significant increased with the increase of generation, and FIS of the 1st generation is significantly lower than that of the second to fifth generation (p < 0.01). The result suggested that the captive population was facing the pressure of inbreeding (FIS = 0.115) and the subsequent loss of genetic diversity. Therefore, it is necessary to improve the breeding management system of the captive population by preventing close relatives from mating or inducing new individuals from the exotic population.

“…It is widespread in forests, plain and low mountains, rather limestone, on well-drained soil, up to 700 m above sea level. It is found in semi-arid and subhumid bioclimatic areas and with warm and fresh bioclimatic variants on floors of thermomediterranean and mesomediterranean vegetation [17].…”
