Noble Crayfish

Background The noble crayfish (Astacus astacus) is a native European species in decline, with a contracting range and diminishing populations and abundance. Previous studies revealed this species significant genetic diversity in the south-eastern Europe, with populations from the western and the southern part of the Balkan Peninsula being the most divergent. However, sampling of populations from the western part of the Balkans was limited and insufficient for investigating genetic diversity and population divergence for the purpose of conservation planning and management. Thus, the major aim of this study was to fill in this knowledge gap by studying mitochondrial and microsatellite DNA diversity, using 413 noble crayfish from 18 populations from waterbodies in the western part of the Balkan Peninsula. Methods Phylogenetic analysis of studied populations and their mitochondrial diversity were studied using COI and 16S sequences and population genetic structure was described using 15 microsatellite loci. Results Phylogeographic analysis revealed new divergent mitochondrial haplotypes for the populations in the westernmost part of the Balkan Peninsula in the tributaries of the Sava and Drava rivers. Microsatellite data indicated that these populations harbour an important component of genetic diversity within A. astacus. The results suggest that the western part of the Balkans played an important role as microrefugia during the Pleistocene climate fluctuations, allowing the long term persistence of A. astacus populations in this region. These results will also be important to supporting conservation decision making and planning.

The genetic diversity of Pakistani dromedary camels is poorly documented. The present study evaluated the genetic variations of two well-known Pakistani camel breeds, Mareecha and Barela, that are well-adapted to the Cholistan desert climate. Camel can serve as a beneficial participant in the food supply chain by providing milk, meat and other food products for the livelihood of pastoral peoples. To explore a new world of resources, greater attention to needed to create standard procedures to genetically characterize, classify and identify camel breeds in the country. For this purpose, 66 unrelated animals of the Mareecha (n=35) and Barela (n=31) breeds were genotyped using a set of 12 labelled microsatellite loci. DNA fragment sizes were determined in an ABI 3130 Genetic Analyzer. All microsatellite markers were successfully amplified and exhibited a polymorphic nature, with an average Polymorphic Information Content (PIC) of 0.72 and 0.70 in Mareecha and Barela, respectively. A total of 107 alleles with an average of 8.91 alleles per locus were identified by these markers in both breeds. CMS15 was highly polymorphic with 13 alleles, while VOLP-032 was the lowest with two loci. The Fit and Fis values were low but high population differentiation (17%) was observed in both breeds, due to the migrations of pastoral people to different remote areas during climate fluctuations.

Late Pleistocene climate oscillations are believed to have greatly influenced the distribution, population dynamics, and genetic variation of many marine organisms in the western Pacific. However, the impact of the late Pleistocene climate cycles on the demographic history and population genetics of pelagic fish in the northern South China Sea (SCS) remains largely unexplored. In this study, we explored the demographic history, genetic structure, and genetic diversity of Decapterus maruadsi, a typical pelagic fish, over most of its range in the northern SCS. A 828–832 bp fragment of mitochondrial control region were sequenced in 241 individuals from 11 locations. High haplotype diversity (0.905–0.980) and low nucleotide diversity (0.00269–0.00849) was detected, revealing low levels of genetic diversity. Demographic history analysis revealed a pattern of decline and subsequent rapid growth in the effective population size during deglaciation, which showed that D. maruadsi experienced recent demographic expansion after a period of low effective population size. Genetic diversity, genetic structure, and phylogenetic relationship analysis all demonstrated that no significant genetic differentiation existed among the populations, indicating that D. maruadsi was panmictic throughout the northern SCS. Periodic sea-level changes, fluctuation of the East Asian Monsoon, and Kuroshio variability were responsible for the population decline and expansion of D. maruadsi. The demographic history was the primary reason for the low levels of genetic diversity and the lack of significant genetic structure. The life history characteristics and ocean currents also had a strong correlation with the genetic homogeneity of D. maruadsi. However, the genetic structure of the population (genetic homogeneity) is inconsistent with biological characteristics (significant difference), which is an important reminder to identify and manage the D. maruadsi population carefully.
