| longitudinal range expansion and cryptic eastern species in the western palaearctic oak gallwasp, andricus coriarius. | the oak gallwasp andricus coriarius is distributed across the western palaearctic from morocco to iran. it belongs to a clade of host-alternating andricus species that requires host oaks in two sections of quercus subgenus quercus to complete its lifecycle, a requirement that has restricted the historic distribution and dispersal of members of this clade. here we present nuclear and mitochondrial sequence evidence from the entire geographic range of a. coriarius to investigate the genetic legacy ... | 2007 | 17498235 |
| use of population genetic data to infer oviposition behaviour: species-specific patterns in four oak gallwasps (hymenoptera: cynipidae). | many species of oak gallwasp (hymenoptera: cynipidae: cynipini) induce galls containing more than one larva (multilocular galls) on their host plant. to date, it has remained unclear whether multilocular galls result solely from clustered oviposition by a single female, or include the aggregated offspring of several females (multiple founding). we have developed a novel maximum-likelihood approach for use with population genetic data that estimates the number and genotypes of parents contributin ... | 2002 | 11886626 |
