Article Reference Where do adaptive shifts occur during invasion? A multidisciplinary approach to unravelling cold adaptation in a tropical ant species invading the Mediterranean area
Evolution may improve the invasiveness of populations, but it often remains unclear whether key adaptation events occur after introduction into the recipient habitat (i.e. post-introduction adaptation scenario), or before introduction within the native range (i.e. prior-adaptation scenario) or at a primary site of invasion (i.e. bridgehead scenario). We used a multidisciplinary approach to determine which of these three scenarios underlies the invasion of the tropical ant Wasmannia auropunctata in a Mediterranean region (i.e. Israel). Species distribution models (SDM), phylogeographical analyses at a broad geographical scale and laboratory experiments on appropriate native and invasive populations indicated that Israeli populations followed an invasion scenario in which adaptation to cold occurred at the southern limit of the native range before dispersal to Israel. We discuss the usefulness of combining SDM, genetic and experimental approaches for unambiguous determination of eco-evolutionary invasion scenarios.

Article Reference Whole-genome shotgun sequencing of mitochondria from ancient hair shafts
Although the application of sequencing-by-synthesis techniques to DNA extracted from bones has revolutionized the study of ancient DNA, it has been plagued by large fractions of contaminating environmental DNA. The genetic analyses of hair shafts could be a solution: We present 10 previously unexamined Siberian mammoth (Mammuthus primigenius) mitochondrial genomes, sequenced with up to 48-fold coverage. The observed levels of damage-derived sequencing errors were lower than those observed in previously published frozen bone samples, even though one of the specimens was >50,000 14C years old and another had been stored for 200 years at room temperature. The method therefore sets the stage for molecular-genetic analysis of museum collections.

Article Reference Woody climbing plants influence the structure of the mountain forest in the Kahuzi-Biega National Park, DR Congo
In the mountain forests of the Kahuzi-Biega National Park (KBNP), in the Democratic Republic of Congo, where Sericostachys scandens, a woody climbing plant in the Amaranthaceae family, is expanding, trees appear to be negatively affected by this liana. In order to contribute to the understanding of the links between the expansion of the liana and the decline of its hosts, we compared the density and the species richness of the trees of dbh (diameter at breast height) ≥5 cm from the plots invaded by S. scandens with those from parcels that are still free from the invasion. The results of the paired unilateral t test applied to the overall sample showed that the tree density is very low in the plots dominated by the liana (p < 0.01), but that species richness is not affected (p > 0.05). In the class with diameter [10–30 cm], the lowest density of trees corresponds to the plots colonized by S. scandens, compared to the places where the liana is not abundant (p < 0.01). Further, the density of trees is significantly lower (p < 0.05) in the classes with diameters [5–10 cm] and ≥30 cm, in plots dominated by S. scandens. In conclusion, the emergence of the liana S. scandens has a negative effect on the density of the trees in the mountain forest of the KBNP. Résumé Dans les forêts de montagne du Parc National Kahuzi-Biega (PNKB), en République Démocratique du Congo, où Sericostachys scandens, plante ligneuse grimpante de la famille des Amaranthaceae, est en plein essor, son feuillage dense encombre les arbres et les étouffe. En vue de contribuer à élucider les liens entre l’expansion de cette liane et le déclin de ses hôtes, la densité et la richesse spécifique des arbres ayant un dbh («diameter at breast height», c’est –à –dire le diamètre mesuré à 1, 30 m au-dessus du sol) ≥5 cm des parcelles envahies par S. scandens ont été comparées à celles des endroits qui ne le sont pas. Le résultat du test t unilatéral par paires appliqué à l’échantillon global a montré que la densité des arbres est très basse dans les parcelles dominées par la liane (p < 0.01), mais qu’il n’y a pas d’effet sur la richesse spécifique (p > 0.05). Dans la classe de diamètre [10–30 cm[, une densité plus faible a été trouvée dans les parcelles colonisées par la liane par rapport à celles où elle n’abonde pas (p < 0.01). En plus, la densité des arbres est significativement basse (p < 0.05) dans les classes de diamètres [5–10 cm[et ≥30 cm dans les parcelles dominées par la liane. L’expansion de la liane S. scandens a donc un effet négatif sur la densité des arbres en forêt de montagne au PNKB.
