<p>We measured genome sizes and determined the karyotypes of nine species of aphid parasitoids in the genus Aphelinus. We found large differences in genome size and karyotype between Aphelinus...
-
Rich, young stellar clusters produce H II regions whose expansion into the nearby molecular cloud is thought to trigger the formation of new stars. However, the importance of this mode of star...
