Insects and incest: field evidence for dangerous liaisons in a parasitoid wasp
1. Sib mating avoidance is a pervasive behaviour, which likely evolves in species that sare subject to inbreeding depression. Laboratory studies have provided elegant demonstrations, but small-scale bioassays often minimize the costs associated with mate finding and mate-choice and may for this reason produce spurious findings. 2. We inferred the mating behaviour of the parasitoid wasp Venturia...
متن کاملDangerous liaisons
Cells during mitosis and meiosis undergo chromosome condensation through a process that depends on evolutionary conserved large protein complexes known as condensins. There are two condensing complexes, condensin i and ii, each of which is composed of five subunits. Condensin i and ii play essential, yet distinct, roles in chromosome condensation and segregation during mitosis. Recent findings ...

The report contrasts the ascertainment of cases by the regional cancer registry with a specially designed search for records and pathology material which was then submitted to critical review irrespective of the original diagnosis. Boundary changes over the intervening years were accounted for and the results contrasted between time periods and with the cancer registry records. A large proporti...
