We used eight polymorphic microsatellite DNA loci to assess the genetic differentiation and diversity of farmed and wild deer populations. Past genetic bottlenecks were detected in both sub-populations, although higher genetic diversity was maintained in farmed populations, probably due to the regular introduction of reproducers from wild populations and from other farms. The genetic structure of farmed and wild populations differed significantly. There was a significant isolation by distance for wild populations, whereas farmed populations were significantly differentiated between farms independently from their geographical proximity. Wild rusa deer consisted of small populations (with effective population sizes ranging between 7 and 19 individuals depending on the methods used), with a low parent-offspring dispersion range (0.20-2.02 km). Genetic tools and direct observations provided congruent estimates of dispersion and population sizes. We discuss the relevance of our results for management purposes. specialized Cervus timorensis russa Population structure Bottleneck New-Caledonia Management Effective population size 080 137 3 313-323 2009 0016-6707 https://www.documentation.ird.fr/hor/fdi:010048371 10.1007/s10709-009-9395-6 0016-6707 [F B010048371] https://www.documentation.ird.fr/hor/fdi:010048371 https://www.documentation.ird.fr/intranet/publi/2009/11/010048371.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2009-12-03 2017-08-23 fdi:010048371 fre
