Reduced genetic diversity in endemic Brazilian Lymania spp (Bromeliaceae) populations and implications for conservation

V. C. C. Pamponét, Alves, T. F., Martinez, R. A., Corrêa, R. X., and Gaiotto, F. A., Reduced genetic diversity in endemic Brazilian Lymania spp (Bromeliaceae) populations and implications for conservation, vol. 12, pp. 4352-4362, 2013.

We analyzed the genetic diversity of populations of two sympatric species of Lymania (Bromeliaceae), both endemic to the Atlantic rainforest of southern Bahia (Brazil). Lymania azurea has a restricted occurrence, while Lymania smithii has a wider distribution. Our aim was to provide genetic data to contribute to the design of more efficient conservation strategies for these bromeliads, possibly justifying inclusion in the official Brazilian list of Endangered Species. Up to now, L.

Isolation and characterization of microsatellite markers for the White Cloud Mountain minnow (Tanichthys albonubes) in wild and cultured populations

J. Zhao, Tseng, D. - Y., Lin, H. - D., and Lin, X. - T., Isolation and characterization of microsatellite markers for the White Cloud Mountain minnow (Tanichthys albonubes) in wild and cultured populations, vol. 10. pp. 2223-2229, 2011.

We developed 12 microsatellite loci for the endangered minnow species, Tanichthys albonubes, using PCR-based isolation of microsatellite arrays. These new markers were tested in 26 individuals from a wild population collected from Guangzhou in China and 26 individuals from a cultured strain. The number of alleles ranged from two to nine and the expected heterozygosity from 0.177 to 0.853.

Application of 16S rRNA, cytochrome b and control region sequences for understanding the phylogenetic relationships in Oryx species

H. A. Khan, Arif, I. A., Homaidan, A. A. Al, and Farhan, A. H. Al, Application of 16S rRNA, cytochrome b and control region sequences for understanding the phylogenetic relationships in Oryx species, vol. 7. pp. 1392-1397, 2008.

The present study reports the application of mitochondrial markers for the molecular phylogeny of Oryx species, including the Arabian oryx (AO), scimitar-horned oryx (SHO) and plains oryx (PO), using the Addax as an outgroup. Sequences of three molecular markers, 16S rRNA, cytochrome b and a control region, for the above four taxa were aligned and the topologies of respective phylogenetic trees were compared. All these markers clearly differentiated the genus Addax from Oryx.
