Altitudinal clinal variation in wing size and shape in African Drosophila melanogaster: one cline or many?
Geographical patterns of morphological variation have been useful in addressing hypotheses about environmental adaptation. In particular, latitudinal clines in phenotypes have been studied in a number of Drosophila species. Some environmental conditions along latitudinal clines-for example, temperature-also vary along altitudinal clines, but these have been studied infrequently and it remains u...
متن کاملSecondary contact and local adaptation contribute to genome-wide patterns of clinal variation in Drosophila melanogaster.
Populations arrayed along broad latitudinal gradients often show patterns of clinal variation in phenotype and genotype. Such population differentiation can be generated and maintained by both historical demographic events and local adaptation. These evolutionary forces are not mutually exclusive and can in some cases produce nearly identical patterns of genetic differentiation among population...
متن کاملClinal variation for amino acid polymorphisms at the Pgm locus in Drosophila melanogaster.
Clinal variation is common for enzymes in the glycolytic pathway for Drosophila melanogaster and is generally accepted as an adaptive response to different climates. Although the enzyme phosphoglucomutase (PGM) possesses several allozyme polymorphisms, it is unique in that it had been reported to show no clinal variation. Our recent DNA sequence investigation of Pgm found extensive cryptic amin...

متن کامل: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
