Tetranychus ludeni Zacher is an invasive pest from Europe. It infests more than 300 plant species, including many economically important crops such as bean Phaseolus vulgaris L. (Fabales: Fabaceae), eggplant Solanum melongena (Solanales: Solanaceae), and other cucurbitaceous plants. Gotoh et al. (2015) predict that this species could replace T. urticae to become a major crop in the world. often...
Lack of genic similarity between two sibling species of drosophila as revealed by varied techniques.
Acrylamide gel electrophoresis was performed on the enzyme xanthine dehydrogenase in sixty isochromosomal lines of Drosophila persimilis from three geographic populations. Sequential electrophoretic analysis using varied gel concentrations and buffers revealed twenty-three alleles in this species where only five had been described previously. These new electrophoretic techniques also detected a...
Most work on adaptive speciation to date has focused on the role of low hybrid fitness as the force driving reinforcement (the evolution of premating isolation after secondary contact that reduces the likelihood of matings between populations). However, recent theoretical work has shown that postmating, prezygotic incompatibilities may also be important in driving premating isolation. We quanti...
Measures of genetic divergence have long been used to identify evolutionary processes operating within and between species. However, recent reviews have described a bias in the use of relative divergence measures towards incorrectly identifying genomic regions that are seemingly immune to introgression. Here, we present a novel and opposite bias of relative divergence measures: misidentifying r...
Genetic variation at 43 loci has been studied in six different populations of Drosophila persimilis by electrophoresis of enzymes and proteins. In D. persimilis the mean proportion of polymorphic loci is 0.362, the mean proportion of heterozygous loci per individual is 0.100 and the average number of alleles per locus is 1.651. In all populations, the loci coding for the hydrolytic and other no...
The Chilean saline lakes are distributed mainly in the Atacama desert in northern Chile and the southern Patagonian plains. The scarce studies are restricted mainly to northern Chilean saline lakes, and these revealed that the main component in these ecosystems are the halophylic copepod Boeckella poopoensis Marsh 1906, or the brine shrimp Artemia franciscana (Kellog, 1906), and both species do...
The genus Habroteleia Kieffer is revised. Seven species are recognized, three are redescribed: H. flavipes Kieffer, H. persimilis (Kozlov & Kononova), H. ruficoxa (Kieffer); and four species are described as new: H. mutabilis Chen & Talamas, sp. n., H. salebra Chen & Talamas, sp. n., H. soa Chen & Talamas, sp. n., and H. spinosa Chen & Johnson, sp. n. Four species are treated as junior synonyms...
