“…In studies with populations of Protium heptaphyllum, it was observed in the Northeast region, a diversity ranging from 0.24 -0.32 (Freire et al, 2019). For Acrocomia aculeata the diversity varied from 0.30 to 0.42 (Oliveira et al, 2012), amplitude from 0.24 to 0.27 for Metrodorea nigra (Moraes Filho et al, 2015) and from 0.36 to 0.42 for Myroxylon peruiferum (Schwarcz et al, 2018).…”

Hancornia speciosa is the target of research on genetic diversity, ethnobotanical and medicinal studies. However, information on the genetic variability of populations associated with modeling the potential distribution in the state of Sergipe has not yet been performed. The objective of this study was to predict the potential occurrence of H. speciosa in areas of high use of their fruits. The maximum entropy method was used to detect the distribution patterns of H. speciosa in variable environments. The diversity of four natural populations, situated in areas of extractivist, was determined by ISSR molecular markers. The species occurs more densely in the coastal regions of Sergipe. The prediction of occurrence indicates that the species reduces areas of occurrence, mainly due to anthropic actions. It is suggested that the species needs public policies aimed at its conservation and the priority populations for conservation.

“…In genotyping Myroxylon peruiferum populations from reforested and remnant natural areas, Schwarcz et al (2018) evaluated the potential of forest restoration for the production of high genetic diversity tree populations in previously deforested areas. Due to the intense gene flow, no significant differences were found between areas in terms of inbreeding (F IS = 0.20) or genetic diversity (H E = 0.31 -0.43; allelic richness = 2.41 -2.94).…”

Microsatellites are important for forest genetic resources conservation in Brazilian biomes

Microsatellites are short sequence repeats that make up the genomes of eukaryotes and prokaryotes. They are of great importance as DNA markers for studies in several fields of genetics. In the present review, we searched for studies published in the five years period of 2017 to 2021 regarding the use of microsatellites in studies with forest tree species from the Brazilian biomes, in order to examine the importance of these markers for forest resources conservation. We searched scientific papers in journals indexed on the Scopus and Web of Science databases. There were found 38 peer reviewed articles that used microsatellites in the Brazilian biomes. The Atlantic Forest was the biome with more studies (35.9 %) and most of the studies were published in 2018 (34.2 %). In addition, most of the studied species belonged to the Fabaceae family (34.2 %). The conclusions and recommendations made in these studies ratify the great contribution of microsatellite markers in the conservation of native forest species in Brazilian biomes.

“…However, empirical evidence does not always support this in other disturbed habitats (Giombini, Bravo, Sica, & Tosto, ; Noreen, Niissalo, Lum, & Webb, ; Rosas, Quesada, Lobo, & Sork, ). Therefore, the genetic consequences for a small population or due habitat disturbance are both species and location specific (Owusu, Schlarbaum, Carlson, & Cailing, ; Schwarcz et al, ). In particular, we also examined the demographic history of Feng Shui populations of E. fordii to study how the current level genetic diversity is related to historical events such as bottlenecks.…”

Feng Shui woodlands are naturally or artificially formed green areas in southern China. They are precious for maintaining ecosystem balance in modern semiurban environments. However, they are generally small and geographically isolated from each other, and the status of genetic diversity of the plant species within them has been almost neglected. Therefore, we studied the genetic diversity of the endangered Erythrophleum fordii in eight Feng Shui woodlands (a total of 1,061 individuals) in Guangzhou, a large city in southern China, using microsatellites. For comparison, one population with 33 individuals sampled in a nature reserve was also studied.Although our results indicate that significant demographic declines occurred historically in E. fordii, such declines have not resulted in consistent reductions in genetic variation over generations in Feng Shui populations in the recent past, and the levels of genetic variation in these populations were higher than or comparable to the genetic variation of the population in the nature reserve. In addition, our parentage and paternity analyses indicated widespread and potential long-distance pollen flow within one Feng Shui woodland, indicating the presence of an unbroken pollination network, which would at least partially alleviate the genetic erosion due to habitat fragmentation and the unequal gene contributions of E. fordii parents to their progenies when favorable recruitment habitats are absent under most of the parent trees.Overall, our results suggest that E. fordii in Feng Shui woodlands may not be driven to extinction in the near future. Nevertheless, uncontrolled fast urban development with a lack of awareness of Feng Shui woodlands will cause the local extinction of E. fordii, which has already happened in some Feng Shui woodlands.
