Patterns of genome size variation in snapping shrimp.
Although crustaceans vary extensively in genome size, little is known about how genome size may affect the ecology and evolution of species in this diverse group, in part due to the lack of large genome size datasets. Here we investigate interspecific, intraspecific, and intracolony variation in genome size in 39 species of Synalpheus shrimps, representing one of the largest genome size dataset...
متن کاملEvaluating the role of genome downsizing and size thresholds from genome size distributions in angiosperms.
PREMISE OF THE STUDY Whole-genome duplications (WGDs) can rapidly increase genome size in angiosperms. Yet their mean genome size is not correlated with ploidy. We compared three hypotheses to explain the constancy of genome size means across ploidies. The genome downsizing hypothesis suggests that genome size will decrease by a given percentage after a WGD. The genome size threshold hypothesis...

Genome size is a strong predictor of cell size and stomatal density in angiosperms.
Across eukaryotes phenotypic correlations with genome size are thought to scale from genome size effects on cell size. However, for plants the genome/cell size link has only been thoroughly documented within ploidy series and small subsets of herbaceous species. Here, the first large-scale comparative analysis is made of the relationship between genome size and cell size across 101 species of a...
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...
