| inferring contemporary levels of gene flow and demographic history in a local population of the leaf beetle gonioctena olivacea from mitochondrial dna sequence variation. | we have studied mitochondrial dna variation in a local population of the leaf beetle species gonioctena olivacea, to check whether its apparent low dispersal behaviour affects its pattern of genetic variation at a small geographical scale. we have sampled 10 populations of g. olivacea within a rectangle of 5 x 2 km in the belgian ardennes, as well as five populations located approximately along a straight line of 30 km and separated by distances of 3-12 km. for each sampled individual (8-19 per ... | 2005 | 15836639 |
| structure and evolution of the mitochondrial control region of leaf beetles (coleoptera: chrysomelidae): a hierarchical analysis of nucleotide sequence variation. | to assess the levels of variation at different evolutionary scales in the mitochondrial (mt) control region of leaf beetles, we sequenced and compared the full mt control region in two genera ( chrysomela and gonioctena), in two species within a genus ( gonioctena olivacea and g. pallida), in individuals from distant populations of these species in europe, and in individuals from populations separated by moderate (10- to 100-km) to short (<5-km) distances. in all individuals, a highly repetitive ... | 2003 | 12569421 |
