dig-cide-es-10261-2669192022-11-30T12:48:42Z Population genetics applied to the ecological restoration of human-disturbed landscapes Garrote, Pedro J. Castilla, Antonio R. Picó, F. Xavier Fedriani, José M. Trabajo presentado en el XV Congreso Nacional de la AEET, celebrado en Plasencia (España) del 18 al 21 de octubre de 2021 Understanding of ecological processes driving the natural (re)colonization of human-disturbed landscapes is crucial to restoring sensitive species and ecosystem services. Specifically, seed dispersal is one of the most critical factors on this (re)colonization process by ensuring seed arrival to these areas. However, few studies have examined how the genetic composition of seed rain varies both spatially and temporally within (re)colonizing plant populations and the potential implications of this variation for ecological restoration (i.e. genetic restoration). Here, we evaluated the spatiotemporal structuring of the genetic variation of naturally established seedlings at a human-disturbed area as a qualitative aspect of the seed dispersal (e.g. level of kinship among co-dispersed seeds). To this end, we intensively monitored the seed rain of the Mediterranean dwarf palm (Chamaerops humilis) during two consecutive years in Doñana National Park (SW Spain), where this palm is mostly dispersed by Eurasian badgers (Meles meles) and red foxes (Vulpes vulpes). For all emerged seedlings (N = 104), by molecular analyses at 12 microsatellite markers, we analyzed the fine-scale spatial genetic structure (FSGS), kinship among individuals and genetic rarity throughoutthe time. We found positive FSGS within seed dispersers’ feces. We found inflated kinship between seedlings coming from a single dispersal event, but decreased kinship among seedlings at greater spatial scales (latrines, population). We also found the genetic rarity of seedlings increased as the seed dispersal season progressed. We shed light on how frugivores control the genetic composition of seed rain and its potential consequences on the natural (re)colonization of human-disturbed landscapes. We emphasize the crucial role of population genetics to improve restoration actions with plants in the long term. 2022-04-12T15:43:25Z 2022-04-12T15:43:25Z 2021-10-18 2022-04-12T15:43:25Z comunicación de congreso http://purl.org/coar/resource_type/c_5794 XV Congreso Nacional de la AEET (2021) http://hdl.handle.net/10261/266919 Sí none |
