Genetic differentiation within the European sea bass (D. labrax) as revealed by RAPD-PCR assays

Article Abstract:

The use of random amplified polymorphic DNA (RAPD)-PCR assays has shown strong within-population RAPD variation in the European sea bass (Dicentrarchus labrax). There was only limited between-population genetic differentiation. It was established that there is an east-west differentiation of Mediterranean sea bass. Both RAPD and alloyzme data indicate that a small proportion of the total variation is attributable to sorting on the basis of ecological criteria.

Inbreeding linked to amphibian survival in the wild but not in the laboratory

Article Abstract:

The effects of inbreeding on the performance of the wood frog larvae in the field and in the laboratory were examined, using microsatellite analysis to establish the percentage and degree of inbreeding in the larvae. Results showed that there was no evidence that inbreeding influenced growth or development in the wild, neither that inbreeding affected survival, growth or development in the laboratory.

Searching the genomes of inbred mouse strains for incompatibilities that reproductively isolate their wild relatives

Article Abstract:

The genomes of classical and recombinant mouse strains are examined and the regions with similar base pairs are characterized that contribute to reproductive isolation.
