The primary focus of tropical forest restoration has been the recovery of forest structure and tree taxonomic diversity, with limited attention given to genetic conservation. Populations reintroduced through restoration plantings may have low genetic diversity and be genetically structured due to founder effects and genetic drift, which limit the potential of restoration to recover ecologically resilient plant communities. Here, we studied the genetic diversity, genetic structure and differentiation using single nucleotide polymorphisms (SNP) markers between restored and natural populations of the native tree Casearia sylvestris in the Atlantic Forest of Brazil. We sampled leaves from approximately 24 adult individuals in each of the study sites: two restoration plantations (27 and 62 years old) and two forest remnants. We prepared and sequenced a genotyping-by-sequencing library, SNP markers were identified de novo using Stacks pipeline, and genetic parameters and structure analyses were then estimated for populations. The sequencing step was successful for 80 sampled individuals. Neutral genetic diversity was similar among restored and natural populations (AR = 1.72 ± 0.005; HO = 0.135 ± 0.005; HE = 0.167 ± 0.005; FIS = 0.16 ± 0.022), which were not genetically structured by population subdivision. In spite of this absence of genetic structure by population we found genetic structure within populations but even so there is not spatial genetic structure in any population studied. Less than 1% of the neutral alleles were exclusive to a population. In general, contrary to our expectations, restoration plantations were then effective for conserving tree genetic diversity in human-modified tropical landscapes. Furthermore, we demonstrate that genotyping-by-sequencing can be a useful tool in restoration genetics.

The understanding of the distribution and richness patterns of species is very important in ecology. Also, for the Cerrado region, this is very important and urgent, because of the strong pressure for new areas designated for agriculture. In five areas of cerrado, an exploratory study was carried out on the diversity, evenness and similarity of moth species. Moths were capturated in a white sheet hung vertically and illuminated by a 250 Watt mercury vapor lamp. The alpha diversity was calculated using the Shannon-Wiener index (H') and the Simpson index (y). The beta diversity was examinated for all sampled localities and estimated by Wittaker's measure. The Sorensen and Jaccard indexes were used to calculate similarity. A total of 11130 individuals, 1064 species and 33 families were collected during the study. Great differences were found in the diversity (H'), and according to this index, the minimum value was 1.60 and highest value was 4.59. From the Simpson index (y), the minimum value was 0.42 and highest 0.96. With both methods, in all localities, these values were significantly different by the T tst (p<0.001). The mean beta diversity found was 0.6929, and the minimum and highest values found were respectively 0.4328 and 0.8615. A positive correlation was found between beta diversity and distances among localities (r2=0.5844, p<0.05). Faunal similarities among sites were low, and the highest value found was 0.4146 by Sorensen index and 0.2615 by Jaccard index. |
