Figure 3 in Preliminary report on the genetic structure of Glyphoglossus molossus (Anura: Microhylidae) from the Khorat Plateauı north-eastern Thailand
Figure 3. Median-joining haplotype network (MJN) illustrating hierarchical relationships among haplotypes represented by sampled populations of Glyphoglossus molossus. Each circle showed a haplotype and the size of each circle is scaled to the number of individuals sharing that haplotype. Branch numbers is proportional to number of mutational steps.

Historical translocations and stocking alter the genetic structure of a Mediterranean lobster fishery
Stocking is often used to supplement wild populations that are overexploited or have collapsed, yet it is unclear how this affects the genetic diversity of marine invertebrate populations. During the 1970s, a lobster stock enhancement programme was carried out around the island of Corsica in the Mediterranean using individuals translocated from the Atlantic coast of France. This included the release of thousands of hatchery-reared post-larval lobsters and several adult individuals, but no monitoring plan was established to assess whether these animals survived and recruited to the population. In this study, we sampled European lobster (<i>Homarus gammarus</i>) individuals caught around Corsica and tested whether they showed Atlantic ancestry. Due to a natural marked phylogeographic break between Atlantic and Mediterranean lobsters, we hypothesised that lobsters with dominant (>0.50) Atlantic ancestry were descended from historical stocking releases. Twenty Corsican lobsters were genotyped at 79 single nucleotide polymorphisms and assignment analysis showed that the majority (13) had dominant Atlantic ancestry. This suggests that the hatchery stocking programme carried out in Corsica during the 1970s, using individuals translocated from the Atlantic coast of France, has likely augmented local recruitment but at a cost of altering the genetic structure of the Corsican lobster population.
Population genetic structure and demographic history of the lone star tick, Amblyomma americanum (Ixodida: Ixodidae): new evidence supporting old records
Range expansions are a potential outcome of climate change. Population genetic structure and demography can be used as tools to evaluate hypotheses on changes in geographic distribution. In this study we explored the genetic variability, population genetic structure, demographic history, and habitat suitability of Amblyomma americanum, a North American tick species that is a known vector of several pathogenic microorganisms. We used a novel double digestion restriction site-associated DNA sequencing (dd-RAD seq), and we discovered 8181 independent single nucleotide polymorphisms (SNPs) from 189 ticks from across the geographic range of the species. Overall, genetic diversity was lower than expected. Further, the edge populations did not have a statistically significant lower diversity than core populations, and hypotheses of range expansion are not supported by a test based on genetic data. Nonetheless, moderate levels of population structure were detected among geographic regions, with the northeast cluster the least variable. Demographic and species distribution models support a scenario where A. americanum was present in more northern locations in the past, underwent a bottleneck, and is now recovering. These findings highlight the importance of demographic modeling and genomic data in assessing the recent history and genetic structure of pathogen vectors.
