“…Other studies have also concluded that extrinsic factors (i.e., unstable environmental conditions) might promote changes in the genetic structure of natural populations of some species (Garant et al 2000;Roark et al 2001;Østergaard et al 2003;Barcia et al 2005;Huang et al 2005;Cena et al 2006). Besides environmental factors, biological factors such as genetic drift and natural selection could also mold genetic patterns (Alam and Islam 2005;Barcia et al 2005;Crispo et al 2006;Mäkinen et al 2006;Gutiérrez-Rodríguez et al 2007;Lee and Boulding 2007;Rahman et al 2008). Genetic drift is most important in small populations, while natural selection is more effective in larger populations and could be enhanced by unstable environments (Frankham et al 2002).…”

Gobiocypris rarus, an endemic cyprinid fish with high fecundity, lives mainly in small water systems easily influenced by changes in natural surroundings. This study used 11 polymorphic microsatellite primers to identify the temporal variation of its topotype population. Moderate genetic diversity, inbreeding phenomena, and limited temporal variation between 1997 and 2006 were revealed in the topotype population. The main temporal fluctuations involved only the change of allelic frequencies over two loci and allelic richness. The effective population size was estimated to be 645. The authors argue that inbreeding did not induce dramatic depression effects on the topotype population, and the forces to maintain genetic diversity were mainly from environmental fluctuations and life history traits. Considering that the topotype population is facing increased habitat loss, destruction, and disturbance due to human activities, the authors suggest that a habitat and species management area be established in the type locality.

“…Further, because they are not easy to rear, few studies of S. formosus have been reported. At present, research on S. formosus has focused mainly on interspecific genetic variations, evolutionary status, and karyotype (Austin, Tan, Croft, Hammer, & Gan, ; Bian et al, ; Mohdshamsudin et al, ; Mu et al, ; Rahman, Zakariaismail, Tang, & Muniandy, ; Tian, Mu, Wang, Gu, & Hu, ). So far, a method to effectively identify the sex of S. formosus has not been discovered.…”

Tissue expression and bioinformatics analysis of the vitellogenin gene of Asian arowana ( Scleropages formosus )

The RACE technique was used to clone the full‐length vitellogenin (VTG) cDNA sequence of Asian arowana (Scleropages formosus). The full‐length sequence was 5,550 bp with an open reading frame of 5,238 bp, encoding 1,745 amino acids, and 5′ and 3′ UTRs (untranslated regions) of 45 bp and 267 bp, respectively. Phylogenetic analysis showed that S. formosus and silver arowana (Osteoglossum bicirrhosum) share a close evolutionary relationship (bootstrap 100%). The quantitative real‐time PCR results showed that vtg expression was significantly higher in liver and gonads of male and female fish compared with its expression in the other tissues tested (p < 0.01). The relative expression levels of vtg in liver, gland, kidney, heart, head kidney, and brain of female fish were significantly higher than in the corresponding tissues of male fish (p < 0.05).
