Genetic structure in populations of Euterpe precatoria Mart. in the Brazilian Amazon
<p><i>Euterpe precatoria</i> is a palm tree belonging to the Arecaceae family, occurring in Western and Central Brazilian Amazonia Its fruit, which is very appreciated in the Amazon region, produces pulp that is consumed in fresh form. Its production is carried out almost exclusively by extractive farmers. In order to establish adequate strategies to sustain this genetic resource. We need knowledge about its diversity and genetic structure in natural populations. This study aimed to evaluate the influence of geographic distance on genetic structure in the main extractive populations of <i>E. precatoria</i> in the Brazilian Amazon. Leaves from 377 plants were collected in 19 populations located in 16 municipalities in the State of Amazonas and three in the State of Rondônia. Twelve microsatellite loci were used to genotype the plants. The diversity and genetic structure among populations were estimated. The average number of alleles per locus was 5.97. The observed heterozygosity means (<i>H<sub>O</sub></i>) were higher than expected (<i>H<sub>E</sub></i>) at the population level (<i>H<sub>O</sub></i> = 0.72, <i>H<sub>E</sub></i> = 0.66) and fixation index (<i>f</i> = -0.100) was negative. The<i> F<sub>ST</sub></i><sub> </sub>value (0.1820) and the AMOVA results (17.961) showed population structure. The populations were clustered into three groups (K = 3) in Bayesian analysis. The Discriminant Analysis of Principal Components (DAPC) confirmed eight clusters, with the populations close to those identified by the Bayesian analysis. The geographic differentiation was confirmed by the groupings obtained in the analyses by the Structure program and the DACP function. Information related to phenotypic, genetic and environmental characterization of populations is important to guide conservation and management strategies and the formulation of public species management policies in Amazonian.</p>
Data from: Pollen flow in fragmented landscapes maintains genetic diversity following stand-replacing disturbance in a neotropical pioneer tree, Vochysia ferruginea Mart.
In forests with gap disturbance regimes, pioneer tree regeneration is typically abundant following stand-replacing disturbances, whether natural or anthropogenic. Differences in pioneer tree density linked to disturbance regime can influence pollinator behaviour and impact on mating patterns and genetic diversity of pioneer populations. Such mating pattern shifts can manifest as higher selfing rates and lower pollen diversity in old growth forest populations. In secondary forest, where more closely related pollen donors occur, an increase in biparental inbreeding is a potential problem. Here, we investigate the consequences of secondary forest colonisation on the mating patterns and genetic diversity of open-pollinated progeny arrays for the long-lived, self-compatible pioneer tree, Vochysia ferruginea, at two Costa Rican sites. Five microsatellite loci were screened across adult and seed cohorts from old growth forest with lower density, secondary forest with higher density, and isolated individual trees in pasture. Progeny from both old growth and secondary forest contexts were predominantly outcrossed (tm=1.00) and experienced low levels of biparental inbreeding (tm−ts=0.00–0.04). In contrast to predictions, our results indicated that the mating patterns of V. ferruginea are relatively robust to density differences between old growth and secondary forest stands. In addition, we observed that pollen-mediated gene flow possibly maintained the genetic diversity of open-pollinated progeny arrays in stands of secondary forest adults. As part of a natural resource management strategy, we suggest that primary forest remnants should be prioritised for conservation to promote restoration of genetic diversity during forest regeneration.

Note the greater number of male flowers collected in the field relative to the female-phase flowers sampled. (b) Floral thermogenesis during one floral cycle. Note that there are two heat production peaks during the night, one at approximately 7.00pm, when the flowers are in the female phase, and another at approximately 11.00pm, when they are in the male phase. During the interim phase, heat production diminishes without ceasing altogether.
