The evolutionary ecology of resistance to parasitoids by Drosophila

Article Abstract:

Resistance to parasitoids by Drosophila and its evolutionary ecology are discussed in this review article. Future work in integration of genetic, ecological, and physiological approaches to the coevolution of virulence and resistance in the system is considered. The most important natural enemies of Drosophila in field populations are parasitoid wasps, Hymenoptera species, that attack pupae or larvae. Drosophila parasitoids have numerous advantages as model organisms in behavioral and behavioral ecological studies and in those of host-parasite physiology. The parasitoids can for the most part be cultured very easily and have short generation times. Genetics of Drosophila parasitoids are still not well understood and that is a drawback. Few visual or molecular markers are available.

Intraspecific genetic variation of striped red mullet (Mullus surmuletus L.) in the Mediterranean Sea assessed by allozyme and random amplified polymorphic DNA (RAPD) analysis

Article Abstract:

An estimate of genetic variation of striped red mullet (Mullus surmuletus L.) in six locations in the Mediterranean Sea using allozyme and random amplified polymorphic DNA (RAPD) analysis is discussed. Results of the two approaches, both of which can give useful information for stock structure analysis, are compared.
