Signiﬁcant reduction in genetic diversity and signiﬁcant diﬀerence in genetic composition of the seedling lots compared to the seed origin stand were detected. The female and the total eﬀective number of parents were quantiﬁed by means of maternity assignment of seedlings and temporal changes in allele frequencies. Extremely low eﬀective maternity numbers were estimated (Nf e ≈ 2–4) and estimates accounting for both seed and pollen donors gave also low values (Ne ≈ 35–50). These values can be explained by an inappropriate forestry seed harvest strategy limited to a small number of spatially close trees.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>3</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Burgarella, C</style></author><author><style face="normal" font="default" size="100%">Navascués, M</style></author><author><style face="normal" font="default" size="100%">FICI, S</style></author><author><style face="normal" font="default" size="100%">LORA GONZÁLEZ, A</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Estudio de la variabilidad genética de repoblaciones de QUERCUS ILEX L.

In the present work the levels of genetic diversity and differentiation between artificial stands of Quercus ilex and the adjacent natural stands are assessed with nuclear microsatellites. Also, it was possible to analyse the natural population used as seed source for one of the reforestations studied. The levels of genetic differentiation between natural and artificial stands and the decrease of genetic diversity from the seed origin population to the reforestation are discussed in relation to the transference of seed among provenance regions and to the seed collection strategy (number of trees used for sampling seeds)</style></abstract></record></records></xml>
