Together stronger: intracolonial genetic variability occurrence in Pocillopora corals suggests potential benefits
<p>We investigated the occurrence of intracolonial genetic variability (IGV) in <em>Pocillopora</em> corals in the Southwestern Indian Ocean. Ninety-six colonies were threefold-sampled from three sites in Reunion Island. Nubbins were genotyped using 13 microsatellite loci and their multilocus genotypes compared. Over 50% of the colonies presented at least two different genotypes among their three nubbins and IGV was found abundant in all sites (from 36.7 to 58.1%). To define the threshold distinguishing mosaicism from chimerism, we developed a new method based on different evolution models by computing the number of different alleles for the Infinite Allele Model (IAM) and the Bruvo’s distance for the Stepwise Mutation Model (SMM). Colonies were considered as chimeras if their nubbins differed from more than four alleles and if the pairwise Bruvo’s distance was higher than 0.12. Thus 80% of the IGV colonies were mosaics and 20% chimeras (representing almost 10% of the total sampling). IGV seems widespread in scleractinians and beyond the disabilities of this phenomenon reported in several studies, it should also bring benefits. Next steps are to identify these benefits and to understand processes leading to IGV, as well as factors influencing them.</p> <p>This dataset contains the 12 loci genotypes of the 288 nubbins.</p>

Genetic variability, management, and conservation implications of the critically endangered Brazilian pitviper Bothrops insularis
<p>Information on demographic, genetic, and environmental parameters of wild and captive animal populations has proven to be crucial to conservation programs and strategies. Genetic approaches in conservation programs of Brazilian snakes remain scarce despite their importance for critically endangered species, such as <i>Bothrops insularis</i>, the golden lancehead, which is endemic to Ilha da Queimada Grande, coast of São Paulo State, Brazil. This study aims to (i) characterize the genetic diversity of <i>ex-situ</i> and <i>in-situ</i> populations of <i>B. insularis</i> using heterologous microsatellites; (ii) investigate genetic structure among and within these populations; and (iii) provide data for the conservation program of the species. Twelve informative microsatellites obtained from three species of the <i>B. neuwiedi</i> group were used to access genetic diversity indexes of <i>ex-situ</i> and <i>in-situ</i> populations. Low-to-medium genetic diversity parameters were found. Both populations showed low — albeit significant — values of system of mating inbreeding coefficient, whereas only the <i>in-situ</i> population showed a significant value of pedigree inbreeding coefficient. Significant values of genetic differentiation indexes suggest a small differentiation between the two populations. Discriminant analysis of principal components (DAPC) recovered five clusters. No geographic relationship was found in the island, suggesting the occurrence of gene flow. Also, our data allowed the establishment of six preferential breeding couples, aiming to minimize inbreeding and elucidate uncertain parental relationships in the captive population. In a conservation perspective, continuous monitoring of both populations is demanded: it involves the incorporation of new individuals from the island into the captive population to avoid inbreeding and to achieve the recommended allelic similarity between the two populations. At last, we recommend that the genetic data support researches as a base to maintain a viable and healthy captive population, highly genetically similar to the <i>in-situ</i> one, which is crucial for considering a reintroduction process into the island.</p>
Data from: Disentangling genetic from environmental effects on phenotypic variability of Southern rock lobster (Jasus edwardsii) postlarvae
<p><span>Environmental conditions experienced during larval dispersal of marine organisms can determine size-at-settlement of recruits. It is, therefore, not uncommon that larvae undergoing different dispersal histories would exhibit phenotypic variability at recruitment. Here we investigated morphological differences in recently settled southern rock lobster (<em>Jasus</em> <em>edwardsii</em>) recruits, known as pueruli, along a latitudinal and temporal gradient on the east coast of Tasmania, Australia. We further explored whether natural selection could be driving morphological variation. We used double digest restriction-site associated DNA sequencing (ddRADseq) to assess differences in genetic structure of recently settled recruits on the east coast of Tasmania over three months of peak settlement during 2012 (August, September and October). Phenotypic differences in pueruli between sites and months of settlement were observed, with significantly smaller individuals found at the northernmost site. Also, there was a lack of overall genetic divergence; however, significant differences in pairwise FST values between settlement months were observed at the southernmost study site, located at an area of confluence of ocean currents. Specifically, individuals settling into the southernmost earlier in the season were genetically different from those settling later. The lack of overall genetic divergence in the presence of phenotypic variation indicates that larval environmental history during dispersal of <em>J</em>. <em>edwardsii</em> could be a possible driver of the resulting phenotype of settlers.</span></p>
Tectona grandis: Narrow Genetic Base? A New Perspective on the Genetic Variability of Teak
Teak (Tectona grandis Linn. f.) is considered one of the most expensive hardwoods in the world. The dispersion of the species over the years has taken the teak beyond its origin centers and little is known about the genetic origin and genetic variability. This study aimed to investigate the genetic diversity and population structure existing in a teak germplasm bank collection in Brazil. DNA was extracted from young leaves and each sample were genotyped by whole genome sequencing at 8x of coverage, the sequencing were aligned using the genome at NCBI, and SNPcalls and quality control were made. To study the population structure of the genotypes, Bayesian variational inference was used via fastStructure, the phylogenetic tree was based on the modified Euclidean distance and the clustering by the UPGMA hierarchical method. Genetic diversity was analyzed based on the pairwise genetic divergence (Fst) of Weir and Cockerham. Genotyping by sequencing resulted in a database of approximately 1.4 million of variations SNPs were used for analysis. It was possible to identify four subpopulations with genetic variability between and within the subpopulations, so this study made it possible to confirm the existence of genetic variability in teak, contrary to what was expected.

THE SONIFICATION OF GENETIC VARIABILITY AS A COMMUNICATION TOOL
<p>An innovative approach that uses sonification to communicate the comparison of individuals and effectively convey their genetic variability. This study culminated in the development of two distinct sonification methods. The methods adopted were audification (Sonification A) and parameter (or musical) mapping sonifications (Sonification B). </p>
