Fig. 4. Logistic curves of the survival of the isopod Tylos capensis (expressed as a percentage) as a functIon of tIme for five dIfferent food treatments: (A) no food (NF); (B) lettuce (L); (C) boneseed leaves (Chrysanthemoides monilifera monilifera) from Jan Marais Nature Reserve (BSM); (D) boneseed leaves (C. monilifera monilifera) from Cape Hangklip (BSH); or (E) bietou bush leaves (Chrysanthemoides monilifera rotundata) from Yzerfontein. The logistic regression lines are plotted through the raw survIval data (shown as unfilled cIrcles) and the estImated mean survIval tImes for 50 and 90 % of each treatment group (LD50 and LD90 respectively) are shown with ± one standard error of the mean.

History of the terrestrial isopod genus Ligidium in Japan based on phylogeographic analysis
<span>Background</span> <p><span>Phylogeographical approaches explain the genetic diversity of local organisms in the context of their geological and geographic environments. Thus, genetic diversity can be a proxy for geological history. Here we propose a genus of woodland isopod, <em>Ligidium</em>, as a marker of geological history in relation to orogeny and the Quaternary glacial cycle. </span></p> <span>Results</span> <p><span>Mitochondrial analysis of 721 individuals from 97 sites across Japan revealed phylogenetic divergence between the northeastern and southwestern Japan arcs from 7 to 3.5 million years ago. It also showed repeated population expansions in northeastern Japan in response to Quaternary glacial and interglacial cycles. Genome-wide analysis of 83 selected individuals revealed multiple genetic nuclear clusters. The genomic groupings were consistent with the local geographic distribution, indicating that the <em>Ligidium</em> phylogeny reflects its migration history.</span></p> <span>Conclusion</span> <p><em><span>Ligidium</span></em><span> DNA sequence analysis can provide insight into the geological, geographical, and paleoenvironmental history of the studied region.</span></p>
