Genetic evidence of gene flow from Indians to Malays. by Teng, Yao Sheng, Tan, Soon Guan

“…The occurrence of specific rare variants PHI 3-1, LDH Calcutta-1 and Madras-1, and Hb S, as well as the gene frequencies of adenylate kinase and haptoglobin in Malays and Indians confirm the gene flow from Indians to Malays.…”

Bioindicator snake shows genomic signatures of natural and anthropogenic barriers to gene flow by Lettoof, Damian, Thomson, V.A., Cornelis, Jari, Bateman, Bill, Aubret, Fabien, Gagnon, Monique, von Takach, Brenton

“…We found that population genomic structure was strongest across the northern and southern sides of a major river system, with the northern cluster of populations exhibiting lower heterozygosities than the southern cluster, likely due to a lack of historical gene flow. We also observed an increasing signal of inbreeding and genetic drift with increasing geographic isolation due to urbanisation. …”

Single-gene speciation: mating and gene flow between mirror-image snails by Richards, Paul M., Morii, Yuta, Kimura, Kazuki, Hirano, Takahiro, Chiba, Satoshi, Davison, Angus

“…We also report evidence of mating between mirror-image morphs, directly showing the potential for gene flow. Thus, theoretical models are suggestive of gene flow between oppositely coiled snails, and our empirical study shows that they can mate and that there is gene flow in Euhadra. …”

Gene flow from Clearfield® rice to weedy rice under field conditions by Engku, A. K., Mazlan, Norida, Juraimi, Abdul Shukor, Yusop, Mohd Rafii, Abdullah, Siti Nor Akmar, Alam, Mohamad Amirul

“…However, there is major concern involving resistant individuals resulting from gene flow as the cultivated and weedy rice live side by side in the fields. …”

Effects of habitat fragmentation on population structure and long-distance gene flow in an endangered marsupial: The woylie by Pacioni, Carlo, Wayne, A., Spencer, P.

“…Additionally, previously undisclosed modern and historical connections between these units became evident, such as the historical connection between populations at 150 km distance (Dryandra and Upper Warren) and the contemporary gene flow between the two populations in Upper Warren (up to 60 km). …”

Restricted gene flow and local adaptation highlight the vulnerability of high-latitude reefs to rapid environmental change by Thomas, L., Kennington, W., Evans, R., Kendrick, G., Stat, Michael

“…In this study, we apply a genotyping-by-sequencing approach to investigate genome-wide patterns of genetic diversity, gene flow, and local adaptation in a reef-building coral, Pocillopora damicornis, across 10 degrees of latitude and a transition from temperate to tropical waters. …”

The Malay Peninsula as a barrier to gene flow in an Asian horseshoe crab species, Carcinoscorpius rotundicauda Latreille by A. B., Adibah, Ng, W. L., Tan, Soon Guan

“…This includes showing that little, although significant, genetic differentiation is present among populations, suggesting a low rate of gene flow among populations. The results also suggested that C. rotundicauda may be subjected to the land barrier effect of the Malay Peninsula, whereby gene flow is limited between populations occurring on both sides of the peninsula, increasing their genetic differentiation through time.…”

Genomic signatures of local adaptation reveal source-sink dynamics in a high gene flow fish species by Cure, K., Thomas, L., Hobbs, Jean-Paul, Fairclough, D., Kennington, W.

“…Most loci (76%) showed low genetic divergence across the species' range, indicating high levels of gene flow and confirming previous findings using neutral microsatellite markers. …”

Limited contemporary gene flow and high self-replenishment drives peripheral isolation in an endemic coral reef fish by van der Meer, M., Horne, J., Gardener, M., Hobbs, Jean-Paul, Prachett, M., Van Herwerden, L.

“…Despite high levels of mtDNA gene flow, there is limited msatDNA gene flow with evidence of high levels of self-replenishment (=76%) at all four locations. …”

Genetic Connectivity among and Self-Replenishment within Island Populations of a Restricted Range Subtropical Reef Fish by van der Meer, M., Hobbs, Jean-Paul, Jones, G., Van Herwerden, L.

“…We infer high levels of gene flow and genetic diversity among locations over evolutionary time, but limited contemporary gene flow amongst locations and high levels of self-replenishment (68 to 84%) within locations over contemporary time. …”

Multilocus analyses indicate a mosaic distribution of hybrid populations in ground squirrels (genus Ictidomys) by Thompson, Cody W., Faisal Ali, Anwarali Khan, Stangl, Frederick B., Baker, Robert J., Bradley, Robert D.

Molecular genetic variation in a widespread forest tree species Eucalyptus obliqua (Myrtaceae) on the island of Tasmania by Bloomfield, J., Nevill, Paul, Potts, B., Vaillancourt, R., Steane, D.

“…Population differentiation based on chloroplast haplotypes was high (G ST=0.69) compared with that based on nuclear microsatellites, suggesting that pollen-mediated gene flow is 150 times the level of seed-mediated gene flow in this animal-pollinated species; hence, pollen is likely to be the main mode of gene flow countering selection along local environmental gradients. …”
