The reproductive system of a tree species has substantial impact on genetic diversity and structure within and among natural populations. Such information, should be considered when planning tree planting for forest restoration. Here, we describe the mating system and genetic diversity of an overexploited Neotropical tree, Myroxylon peruiferum L.f. (Fabaceae) sampled from a forest remnant (10 seed trees and 200 seeds) and assess whether the effective population size of nursery-grown seedlings (148 seedlings) is sufficient to prevent inbreeding depression in reintroduced populations. Genetic analyses were performed based on eight microsatellite loci. M. peruiferum presented a mixed mating system with evidence of biparental inbreeding ( tm-ts = 0.118). We found low levels of genetic diversity for M. peruiferum species (allelic richness: 1.40 to 4.82; expected heterozygosity: 0.29 to 0.52). Based on Ne(v) within progeny, we suggest a sample size of 47 seed trees to achieve an effective population size of 100. The effective population sizes for the nursey-grown seedlings were much smaller ( Ne = 27.54 to 34.86) than that recommended for short term ( Ne ≥ 100) population conservation. Therefore, to obtain a reasonable genetic representation of native tree species and prevent problems associated with inbreeding depression, seedling production for restoration purposes may require a much larger sampling effort than is currently used, a problem that is further complicated by species with a mixed mating system. This study emphasizes the need to integrate species reproductive biology into seedling production programs and connect conservation genetics with ecological restoration.
Genotyping Data of the Myroxylon peruiferum
Genotyping data of the mating system and seedlings of an overexploited Neotropical tree. We fist assessed the mating system of Myroxylon peruiferum in a forest remnant population found in the Caetetus Ecological Station, São Paulo State, southeastern Brazil. We further selected four forest nurseries that supply seedlings to restoration in the municipalities of Penápolis, Capão Bonito, Socorro and Ibaté.
We used any abbreviations: COD – individual code; FAMLAB – family label; and NURLAB – nursery label.
