Data from: Population genetics of a broadcast-spawning coral across a tropical-temperate transition zone reveals regional differentiation and isolation of high-latitude reefs
<p>Aim: Genetic connectivity is a key component of species resilience to climate change in terms of recovery capacity following disturbance and capacity to disperse to novel locations as the climate warms and isotherms shift poleward. We aimed to strengthen our understanding of resilience in this context by characterizing patterns of connectivity and genetic diversity in a broadcast spawning coral across a tropical-temperate transition zone. We hypothesize genetic differentiation between tropical and temperate populations and decreasing genetic diversity with higher latitudes.</p> <p>Location: Western Australia (WA).</p> <p>Taxon: <i>Turbinaria </i>species complex. <i>Turbinaria reniformis </i>Oken, 1815 (Dendrophylliidae).</p> <p>Methods: Samples from 930 target corals were collected from ten locations between 13 - 32<sup> o</sup> latitude spanning a 9° C mean temperature range. <i>In-situ</i> species identification of <i>T. reniformis </i>is hindered by morphological plasticity and homoplasy with sister species. We<i> </i>combined Sanger sequencing of two mitochondrial DNA markers and high-throughput genotyping by sequencing (GBS) to isolate a single genetic <i>Turbinaria</i> lineage from our dataset through which patterns of genetic flow and diversity along the WA coastline could be explored using population- and individual-based analyses.</p> <p>Results: Mitochondrial DNA sequence variation was low among <i>Turbinaria</i> samples and could not resolve individual species. Using GBS, we identified three genetically distinct lineages. Subsequent analyses within one of these lineages revealed strong spatial subdivision with 2-3 genetic clusters. While temperate populations were genetically diverged from more tropical sites, we did not observe declines in genetic diversity with latitude.</p> <p>Main Conclusions: Temperate coral populations in Western Australia are genetically isolated from their tropical counterparts. Tropical populations of <i>T. 'reniformis' </i>exhibit adequate connectivity.<i> </i>Shark Bay represents the current southern limit of the tropical population of <i>T. 'reniformis'</i>. Interestingly, temperate <i>T. 'reniformis'</i> in this study exhibit some genetic resilience due to their relatively high genetic diversity, yet the strong patterns of genetic subdivision for this widely dispersing coral species potentially limit their resilience to future climate scenarios.</p>
Coherent, atomically thin transition-metal dichalcogenide superlattices with engineered strain
<p>The sample is coherent WS<sub>2</sub>-WSe<sub>2</sub> superlattice (Xie, et al. Science 359, 1131-1136 (2018)). The datasets were collected by electron microscope pixel array detector (EMPAD) under the condition described in this paper (Han, et al. Nano Letters, 18, 3746-3751 (2018)). The rotation angle between the real space and diffraction space in these datasets is 37 degrees. The data have also been analyzed in our recent paper (arXiv:2111.06496) and a conference proceeding (Shi, et al. Microsc. Microanal. 27 Suppl 1, 2021). </p>

Data from: Evolutionary transition from a single RNA replicator to a multiple replicator network
<p><span>In prebiotic evolution, self-replicating molecules are believed to have evolved into complex living systems by expanding their information and functions open-endedly. Theoretically, such evolutionary complexification could occur through successive appearance of novel replicators that interact with one another to form replication networks. Here we perform long-term evolution experiments of RNA that replicates using a self-encoded RNA replicase. The RNA diversifies into multiple coexisting host and parasite lineages, whose frequencies in the population initially fluctuate and gradually stabilize. The final population, comprising five RNA lineages, forms a replicator network with diverse interactions, including cooperation to help the replication of all other members. These results support the capability of molecular replicators to spontaneously develop complexity through Darwinian evolution, a critical step for the emergence of life.</span></p>
