Data from: Predominant east to west colonisations across major oceanic barriers: insights into the phylogeographic history of the hydroid superfamily Plumularioidea, suggested by a mitochondrial DNA barcoding marker
We provide preliminary insights into the global phylogeographic and evolutionary patterns across species of the hydrozoan superfamily Plumularioidea (Cnidaria: Hydrozoa). We analysed 1114 16S sequences of 198 putative species of Plumularioidea collected worldwide. We investigated genetic connections and divergence in relation to present-day and ancient biogeographic barriers, climate changes and oceanic circulation. Geographical distributions of most species are generally more constrained than previously assumed. Some species able to raft are dispersed widely. Human-mediated dispersal explains some wide geographical ranges. Trans-Atlantic genetic connections are presently unlikely for most of the tropical-temperate species, but were probably more frequent until the Miocene-Pliocene transition, before restriction of the Tethys Sea and the Central American Seaway. Trans-Atlantic colonisations were predominantly directed westwards through (sub)tropical waters. The Azores were colonized multiple times and through different routes, mainly from the east Atlantic, at least since the Pliocene. Extant geminate clades separated by the Isthmus of Panama have predominantly Atlantic origin. Various ancient colonisations mainly directed from the Indian Ocean to the Atlantic, occurred through the Tethys Sea and around South Africa in periods of lower intensity of the Benguela upwelling. Thermal tolerance, population sizes, dispersal strategies, oceanic currents, substrate preference and land barriers are important factors for dispersal and speciation of marine hydroids.
Data from: Late Quaternary environmental and human impacts on the mitochondrial DNA diversity of four commensal rodents in Myanmar
<p>We addressed the spatiotemporal characteristics of four commensal rodent species occurring in Myanmar in comparison with other areas of the Indo-Malayan region. We examined sequence variations of the mitochondrial cytochrome <i>b</i>gene (<i>Cytb</i>) in the Pacific rat (<i>Rattus exulans</i>), roof rat(<i>Rattus rattus</i>complex, RrC), lesser bandicoot rat (<i>Bandicota bengalensis</i>), and house mouse(<i>Mus musculus</i>) using the recently developed time-dependent evolutionary rates of mtDNA. The <i>Cytb</i>sequences of RrC from Myanmar were shown to belong to RrC Lineage II, and their level of genetic diversity was relatively high compared to those of the other three species. RrC was found to have experienced bottleneck and rapid expansion events at least twice in the late Pleistocene period in Myanmar and a nearby region. Accordingly, paleoclimatic environmental fluctuations were shown to be an important factor affecting rodents in the subtropics of the Indo-Malayan region. Our results show that human activities during the last 10,000 years of the Holocene period affected the population dynamics of the rodent species examined, including introducing them to Myanmar from neighboring countries. Further study of these four commensal rodents in other geographic areas of the Indo-Malayan region would allow us to better understand the factors that drove their evolution and their ecological trends.</p>
Data from: Population genetic structure and intraspecific genetic distance of Periplaneta americana (Blattodea: Blattidae) based on mitochondrial and nuclear DNA markers
<p>The American cockroach (<i>Periplaneta americana</i>) is a globally invasive pest that can cause significant economic loss and threaten human health. Although it is abundant and lives in close proximity to humans, few studies have investigated the genetic diversity of <i>P. americana</i>. Our study analyzed 1053 <i>P. americana</i> and other <i>Periplaneta</i> species' samples from different locations in China and the USA. A traditional tree-based method using 17 unique mitochondrial COI haplotypes of <i>P. americana</i> and 20 haplotypes of the other <i>Periplaneta</i> species accurately identified <i>P. americana</i> with a barcoding threshold of 5.1%. To identify the population genetic structure of <i>P. americana,</i> we investigated <i>wingless</i> gene and pooled them with obtained mtDNA data for a combined analysis. Although the genetic diversity of the USA group was relatively higher than the China group, the number of haplotypes and alleles of both groups was small. Molecular variance (AMOVA), intraspecific phylogeny, and haplotype networks indicated that <i>P. americana</i> had very little global genetic differentiation. The weak geographic genetic structure might reflect the human-mediated dispersal of <i>P. americana</i>. Despite no apparent phylogeographic assignment of mtDNA and nuclear lineages was observed in both BI trees, the integrated COI sequence data identified four distinct <i>P. americana</i> haplotype groups, showing four ancient maternal lineages of <i>P. americana</i> in China and the USA.</p>
