Abstract: Salamanders (urodela) have among the largest vertebrate genomes, ranging in size from 10 to 120 pg. The urodela are divided into ten extant families each with a characteristic range in genome size. Although changes in...
متن کاملGenome size variation in lepidopteran insects
Little information is available on genome size diversity among insects, even in otherwise well-studied groups such as the Lepidoptera. In fact, only six lepidopteran species have been studied to date. The present study therefore represents the first attempt to survey genome size variation in this group, giving estimates for more than 50 species and increasing the coverage of the order to 15 fam...
متن کاملGenome size variation in deep-sea amphipods
Genome size varies considerably across taxa, and extensive research effort has gone into understanding whether variation can be explained by differences in key ecological and life-history traits among species. The extreme environmental conditions that characterize the deep sea have been hypothesized to promote large genome sizes in eukaryotes. Here we test this supposition by examining genome s...
متن کاملCytotype diversity and genome size variation in eastern Asian polyploid Cardamine (Brassicaceae) species.
BACKGROUND AND AIMS Intraspecific ploidy-level variation is an important aspect of a species' genetic make-up, which may lend insight into its evolutionary history and future potential. The present study explores this phenomenon in a group of eastern Asian Cardamine species. METHODS Plant material was sampled from 59 localities in Japan and Korea, which were used in karyological (chromosome c...
متن کاملEcological patterns of genome size variation and the origin of species in salamanders
Salamanders (urodela) have among the largest vertebrate genomes, ranging in size from 10 to over 80 pg. The urodela are divided into ten extant families each with a characteristic range in genome size. Although changes in genome size often occur randomly and in the absence of selection pressure, non‐random patterns of genome size variation are evident among specific vertebrate lineages. Here we...
