From pond 1 to 11 the proportion of genetic material of the invasive T. carnifex (blue) decreases, whereas that of the native, threatened T. cristatus (red) increases. The top panel also shows the distribution of mitochondrial DNA in the ponds (using the same color scheme); note that it underestimates the spread of T.

the way, this pond is the type locality for ivanbureschi, we didn't put this picture in the original paper, not sure why actually.https://benwielstra.com/wp-content/uploads/2014/06/3c.jpg3cThis figure might look a bit complex but sums up the genetic identity of the Vrtovać newts. The bottom left corner represents a pure macedonicus genotype and the bottom right pure karelinii (now ivanbureschi). The top of the triangle represents pure F1 (first generation) hybrids. This plot is made with the HIest R package by Ben Fitzpatrick. https://benwielstra.com/wp-content/uploads/2014/06/3b.jpg3bhttps://benwielstra.com/wp-content/uploads/2014/06/3a.jpg????????????????????????????Pim at the pond2018-07-10T10:47:22+00:00monthlyhttps://benwielstra.com/2014/03/01/climate-and-phylogenetic-signal/2017-11-07T21:57:18+00:00monthlyhttps://benwielstra.com/2017/06/28/carpathian-refugia-within-refugia-evidence-from-two-newts/https://benwielstra.com/wp-content/uploads/2017/06/15-tcri-lmon.jpg15 Tcri Lmon2017-10-26T03:33:00+00:00monthlyhttps://benwielstra.com/2014/06/09/triturus-goes-genomics-kind-of/https://benwielstra.com/wp-content/uploads/2014/06/2b.jpg2bhttps://benwielstra.com/wp-content/uploads/2014/06/2.jpg?????????????????2017-04-20T16:41:46+00:00monthlyhttps://benwielstra.com/2014/06/06/mitochondrial-mess-up/https://benwielstra.com/wp-content/uploads/2014/06/1-mtdna-introgression1.jpg?????????????????2017-04-20T16:41:02+00:00monthlyhttps://benwielstra.com/2014/08/29/ribs-n-genes-triturus-hybrid-zones/2017-04-20T16:38:47+00:00monthlyhttps://benwielstra.com/2015/02/10/a-crested-newt-refugium-in-the-carpathians/https://benwielstra.com/wp-content/uploads/2015/02/fig-1-corrected.jpgFig. 1 CORRECTEDhttps://benwielstra.com/wp-content/uploads/2015/02/fig-2-mtdna-phylogeny-corrected.jpgFig. 2 correctedhttps://benwielstra.com/wp-content/uploads/2014/08/7b-enm.jpg7b ENMThese ecological niche models show area predicted suitable for T. cristatus nowadays (top) and at the height of the last glacial period, the Last Glacial Maximum (c. 21,000 years ago).https://benwielstra.com/wp-content/uploads/2014/08/7c-genetic.jpg7c geneticThe genetic diversity for T. cristatus is high in the Carpathian region (two lower panels; mitochondrial DNA (left) and nuclear DNA show three main genetic groups, populations in grey are genetically admixed with other crested newt species). However, genetic diversity is basically zero in the rest of its range (top panel; one genetic group only). In the lower panels the Carpathian mountain range is shaded grey.https://benwielstra.com/wp-content/uploads/2014/08/7a-europe-map.jpg7a Europe mapThe three southern European peninsulas – Iberian, Italian and Balkan – played a major part as glacial refugia. Many temperate species had their ranges reduced to one of these peninsulas during glacial periods and colonized the rest of their European from here as glacial conditions alleviated. The Carpathians are now increasingly being recognized as a relatively northern glacial refugium.2017-04-20T03:25:48+00:00monthlyhttps://benwielstra.com/2014/10/23/trying-to-crack-the-crested-newt-phylogeny-and-failing/https://benwielstra.com/wp-content/uploads/2014/08/6c-nudna-tree.jpg6c nuDNA treeThe new <em>Triturus</em> tree based on an order of magnitude more nuclear genes than previously studied is a mess. There is no support for any particular branching order and provides no insight into the evolution of the number of ribs at all.https://benwielstra.com/wp-content/uploads/2014/08/6b-mtdna-tree.jpg6b mtDNA treeThe branching order in Triturus based on full mitochondrial genomes is fully in line with a scenario of body shape evolution involving the least possible evolutionary steps required (here expressed as additions of rib-bearing vertebrae). I dare you to you can find a tree that explains the variation in the number of ribs requiring less steps.https://benwielstra.com/wp-content/uploads/2014/08/6a-elongation.png6a elongation2017-04-20T03:25:09+00:00monthlyhttps://benwielstra.com/2014/09/17/mapping-the-european-triturus-species/https://benwielstra.com/wp-content/uploads/2014/08/4-distribution.jpg4 DistributionThis is an overview of all the European grid cells that have Triturus localities (with cells having more than one species coloured blue rather than red).
