| mitochondrial dna markers reveal high genetic diversity but low genetic differentiation in the black fly simulium tani takaoka & davies along an elevational gradient in malaysia. | the population genetic structure of simulium tani was inferred from mitochondria-encoded sequences of cytochrome c oxidase subunits i (coi) and ii (coii) along an elevational gradient in cameron highlands, malaysia. a statistical parsimony network of 71 individuals revealed 71 haplotypes in the coi gene and 43 haplotypes in the coii gene; the concatenated sequences of the coi and coii genes revealed 71 haplotypes. high levels of genetic diversity but low levels of genetic differentiation were ob ... | 2014 | 24941043 |
| molecular phylogeny of black flies in the simulium tuberosum (diptera: simuliidae) species group in thailand. | black flies are medically and ecologically significant insects. they are also interesting from an evolutionary standpoint regarding the role of chromosomal change and ecological adaptation. in this study, molecular genetic markers based on multiple gene sequences were used to assess genetic diversity and to infer phylogenetic relationships for a group of cytologically highly diverse black flies of the simulium tuberosum species group in thailand. ecological affinities of the species were also in ... | 2014 | 24564215 |
| phylogeography of the black fly simulium tani (diptera: simuliidae) from thailand as inferred from mtdna sequences. | intraspecific phylogeography has been used widely as a tool to infer population history. however, little attention has been paid to southeast asia despite its importance in terms of biodiversity. here we used the cytochrome oxidase i gene of mitochondrial dna (mtdna) for a phylogeographic study of 147 individuals of the black fly simulium tani from thailand. the mtdna revealed high genetic differentiation between the major geographical regions of north, east and central/south thailand. mismatch ... | 2005 | 16262854 |
| macrogenomic evidence for the origin of the black fly simulium suzukii (diptera: simuliidae) on okinawa island, japan. | to determine the geographic origin of the black fly simulium suzukii on okinawa island, japan, macrogenomic profiles derived from its polytene chromosomes were compared with those of mainland and other insular populations of s. suzukii and of the isomorphic simulium tani species complex. the okinawan population is a chromosomally unique cytoform, designated 'd,' which is essentially monomorphic and differs by about 27 fixed rearrangements from the chromosomal standard sequence for the subgenus s ... | 2013 | 23951001 |
| vietnam, a hotspot for chromosomal diversity and cryptic species in black flies (diptera: simuliidae). | the increasing attention on vietnam as a biodiversity hotspot prompted an investigation of the potential for cryptic diversity in black flies, a group well known elsewhere for its high frequency of isomorphic species. we analyzed the banding structure of the larval polytene chromosomes in the simulium tuberosum species group to probe for diversity beyond the morphological level. among 272 larvae, 88 different chromosomal rearrangements, primarily paracentric inversions, were discovered in additi ... | 2016 | 27695048 |
| delineating taxonomic boundaries in the largest species complex of black flies (simuliidae) in the oriental region. | perspicuous assessments of taxonomic boundaries and discovery of cryptic taxa are of paramount importance in interpreting ecological and evolutionary phenomena among black flies (simuliidae) and combating associated vector-borne diseases. simulium tani takaoka & davies is the largest and perhaps the most taxonomically challenging species complex of black flies in the oriental region. we use a dna sequence-based method to delineate currently recognized chromosomal and morphological taxa in the s. ... | 2016 | 26839292 |
| breeding habitat preference of preimaginal black flies (diptera: simuliidae) in peninsular malaysia. | to investigate the breeding habitat preference of black flies, a comprehensive black fly survey was conducted for the first time in peninsular malaysia. preimaginal black flies (pupae and larvae) were collected manually from 180 stream points encompassing northern, southern, central and east coast of the peninsular malaysia. a total of 47 black fly species were recorded in this study. the predominant species were simulium trangense (36.7%) and simulium angulistylum (33.3%). relatively common spe ... | 2016 | 26476394 |
| distribution pattern of black fly (diptera: simuliidae) assemblages along an altitudinal gradient in peninsular malaysia. | preimaginal black flies (diptera: simuliidae) are important components of the stream ecosystem. however, there has been limited research undertaken on the vertical distribution of preimaginal black flies and their associated ecological factors. stream conditions are generally variable along the altitudinal gradient. therefore, we conducted an in-depth entomological survey to investigate the simuliid distribution pattern along an altitudinal gradient in peninsular malaysia. | 2016 | 27094088 |
