Data from: Entangled fates of holobiont genomes during invasion: nested bacterial and host diversities in Caulerpa taxifolia
Successful prevention and mitigation of biological invasions requires retracing the initial steps of introduction, as well as understanding key elements enhancing the adaptability of invasive species. We studied the genetic diversity of the green alga Caulerpa taxifolia and its associated bacterial communities in several areas around the world. The striking congruence of α and ß diversity of the algal genome and endophytic communities reveals a tight association, supporting the holobiont concept as best describing the unit of spreading and invasion. Both genomic compartments support the hypotheses of a unique accidental introduction in the Mediterranean and of multiple invasion events in Southern Australia. In addition to helping with tracing the origin of invasion, bacterial communities exhibit metabolic functions that can potentially enhance adaptability and competitiveness of the consortium they form with their host. We thus hypothesize that low genetic diversities of both host and symbiont communities may contribute to the recent regression in the Mediterranean, in contrast with the persistence of highly diverse assemblages in southern Australia. This study supports the importance of scaling up from the host to the holobiont for a comprehensive understanding of invasions.

Caulerpa-associated bacterial 16S rRNA in response to environmental stress
<p>This dataset contains data from a<span>lgal-associated bacteria from the green macroalgae, <i>Caulerpa, </i>from the paper " Morrissey, K.L. et al. (2021) Impacts of environmental stress on resistance and resilience of algal-associated bacterial communities. Ecology and Evolution". </span>The experiment investigates the effects of a factorial combination of nutrient and temperature stress on the bacterial communities. We have also assessed the<span> resistance and resilience of the algal-associated microbiota to environmental stress, using community dissimilarity metrics. </span></p> <p><span>Bacteria were characterised using the 16S rRNA gene and the community compositions were compared between </span>different parts of the algal thallus (endo-, epi- and rhizomicrobiome).</p> <p><span>The results of this study provide evidence that nutrient enrichment has a significant influence on the taxonomic and functional structure of the epimicrobiota, with a low community resistance index observed for both. Temperature and nutrient stress had a significant effect on the rhizomicrobiota taxonomic composition, exhibiting the lowest overall resistance to change. The functional performance of the rhizomicrobiota had low resilience to the combination of stressors, indicating potential additive effects. Interestingly, the endomicrobiota had the highest overall resistance, yet the lowest overall resilience to environmental stress. This further contributes to our understanding of algal microbiome dynamics in response to environmental changes.</span></p>
