| some factors effecting algal consumption in subarctic ephemeroptera, plecoptera and simuliidae. | some of the factors influencing algal consumption in the mayflies leptophlebia nebulosa, cinygmula tarda, baetis foemina and b. cf. bicaudatus, the plecopterans arcynopteryx signata, nemoura cinctipes and n. oregonensis and in the dipterans simulium arcticum, s. venustum and s. decorum were investigated between june 1975 and june 1976 in several streams in the canadian subarctic. algae represented up to 65% of the gut contents of l. nebulosa but only 0-8% in the other mayflies. they were importa ... | 1977 | 28308977 |
| monitoring of methoxychlor residues in the athabasca river system in northern alberta after treatment for control of black fly larval populations. | methoxychlor (2,2-bis(p-methoxyphenyl)-1,1,1-trichloroethane) was used in the athabasca river in northern alberta for the control of black fly larvae, simulium arcticum, during may to july of 1981 to 1987. samples of river water and sediment were analyzed for methoxychlor residues each year as part of alberta environment's program to assess environmental impact and monitor compliance with issued permits. during 1985 fish samples were also collected at various sites downstream and upstream of the ... | 1993 | 24221057 |
| the speciation continuum: population structure, gene flow, and maternal ancestry in the simulium arcticum complex (diptera: simuliidae). | comparative analyses of populations at different stages of divergence can yield insights into the process of speciation. we assess population structure, gene flow, and maternal ancestry at five locations containing sympatric members of the simulium arcticum complex at different stages of chromosome divergence. we analyze both nuclear and mitochondrial dna markers, including 11 microsatellite loci, as well as coi, coii, cytb, and nd4 gene sequences. simulium negativum, representing the later stag ... | 2014 | 24821619 |
| genetic panmixia within a narrow contact zone between chromosomally and ecologically distinct black fly sibling species (diptera: simuliidae). | hybrid zones are windows into the speciation process, and their study can give clues into the maintenance and breakdown of species boundaries. using both genetic and ecological tools, we investigate lineage diversification across a contact zone characterized by chromosome rearrangements. we show that black fly sibling species, simulium arcticum sensu stricto (s.s.) and simulium saxosum, lack genetic differentiation at both microsatellite and mtdna loci in allopatry and sympatry, as well as exhib ... | 2015 | 26108141 |
| isolation and characterization of 11 microsatellite loci from the black fly, simulium negativum (diptera: simuliidae). | eleven polymorphic microsatellite loci were isolated and developed from the black fly, simulium negativum, a member of the simulium arcticum sibling species complex. the observed heterozygosity of the 11 loci ranged from 0.03 to 0.83. the number of alleles per locus ranged from 8 to 19. significant linkage disequilibria were encountered only for the primer pairs bf7-1 with bf7-5 and bf6-32 with bf7-16. presumably, these microsatellite loci can be used to study genetic structure within the entire ... | 2009 | 21564808 |
| good species behaving badly: non-monophyly of black fly sibling species in the simulium arcticum complex (diptera: simuliidae). | mitochondrial based phylogenetic reconstructions often show deviations from species-level monophyly. we used the simulium arcticum species complex (diptera: simuliidae) as a model system for interpreting non-monophyly in light of chromosomal data supporting species status of siblings. for cytogenetic identification of morphologically indistinguishable black fly sibling species, larvae must be preserved in carnoy's solution, a fixative known to degrade dna. consequently, we reconstructed phylogen ... | 2010 | 20601001 |
