Population Genetic Variation

The genus Parapenaeopsis is an important group of marine shrimps for wild capture in the Indo-West Pacific region. Phylogenetics of penaeid shrimps is still a debatable issue. This study focuses on the phylogenetic relationships among seven species within the genus Parapenaeupsis, the population genetic variation of Parapenaeupsis sculptilis along Bangladesh coastline of the Bay of Bengal and the phylogeography of P. sculptilis in the Indian Ocean region by analysing cytochrome oxidase subunit 1 barcode (CO1) sequence. No population structure was detected in P. sculptilis collected from two sampling sites along the Bangladesh coastline (AMOVA and Φ ST = ‑0.014, p > 0.05; F ST = 0.061, p = 0.04), which expanded first around 73 (CI: 36‑119) kyr ago. The genealogical relationships in Bangladesh P. sculptilis population are shallow with haplotype diversity (h) of 0.58 and nucleotide diversity (π) of 0.0014. The different P. sculptilis samples from Bangladesh, India and Mozambique of the Indian Ocean revealed connectivity between western Indian Ocean and the Bay of Bengal. The phylogeny within the genus Parapenaeupsis showed a polyphyletic relationships for P. hardickwii and its taxonomy needs to be reevaluated. The study will help for genetic upgradation in aquaculture and monitoring of the population genetic diversity of P. sculptilis.

The Mean

There are two stocks of American paddlefish Polyodon spathula in Poland, one in Pogorze and the other in Wasosze. These stocks were established from small quantities of eggs imported from the USA in 1995. In this study, we examined genetic variation at seven microsatellite loci in adult fish from the two Polish farms and one stock farmed in Gorny Tykich in Ukraine. Our data were compared with those reported for one native population from the Mississippi River (USA). The polymorphism of examined loci varied in the Polish and Ukrainian stocks, showing 25&minus;30 alleles across each stock (3.6&ndash;4.3 alleles per locus), though they were less polymorphic than those in the Mississippi (49 across the population, 7.0 per locus). The mean observed heterozygosity per locus estimated in Polish stocks (0.59&minus;0.60) was comparable to that found in the Mississippi (0.68). The Garza-Williamson index and values of the heterozygosity excesses revealed a reduction of genetic variation in all the three European stocks (probably resulting from bottleneck or founder effect). Finally, genetic distance measurements confirmed a closer relationship between Pogorze and Wasosze <br />(F<sub>ST </sub>= 0.007) stocks than between these two Polish stocks and that from Ukraine (F<sub>ST</sub> = 0.096 and F<sub>ST </sub>= 0.054). &nbsp;

Mobility Data

An investigation of genetic variation in the electrophoretic mobility of the enzyme a-galactosidase A (EC 3.2.1.22) has been carried out for 33 species of Australian metatherian (marsupial) mammals. The results are compatible with the enzyme being sex-linked in macropodids (kangaroos and wallabies) and probably in dasyurids (marsupial 'mice', etc.), as it is in eutherian (placental) mammals. The results also suggest that the mode of dosage compensation for this locus is the same as for other sexlinked loci in kangaroos, i.e. paternal X inactivation, rather than the random X inactivation system of eutherian mammals. The bearing of the enzyme mobility data on phylogenetic relationships among macropodid species is discussed.
