ABSTRACTThe fungal pathogen Neonectria neomacrospora is of increasing concern in Europe where, within the last decade, it has caused substantial damage to forest stands and ornamental trees of the genus Abies (Mill.). Using whole-genome sequencing of a comprehensive collection of isolates, we show the extent of three major clades within N. neomacrospora, which most likely diverged around the end of the last Ice Age. We find it likely that the current European epidemic of N. neomacrospora was founded from a population belonging to the east North American clade. All European isolates (1957-2019) had a common evolutionary history, but substantial and asymmetrical gene flow from the larger American source population could be detected. The European population shows multiple signs of having gone through a bottleneck and subsequent population expansion.

Le Canada et les politiques internationales sur le pétrole: Source latino-américaine d'approvisionnement et vulnérabilité de l'importation dans les années 1980Cet article étudie le degré de dépendance du Canada vis-à-vis les importations de pétrole brut (mesurée par la proportion de la consommation totale fournie par les importations) et l'étendue de la vulnérabilité découlant de cette dépendance dans l'hypothèse d'un tarissement, à la source, dans les années 1980. Non settlement le Canada est-il devenu de plus en plus dépendant de ses importations de pétrole brut, mais sa dépendance vis-à-vis des pays du Moyen-Orient s'est accrue de manière significative. Cet article tend à prouver que la dépendance du Canada va s'amplifier, du moins à moyen terme et que les fournisseurs du Moyen-Orient (et plus spécifiquement les Etats du golfe persique comme l'Arabie Saoudite) vont continuer à fournir un part de plus en plus grande de notre pétrole brut, à moins que le Canada ne cherche à diversifier ses sources d'approvisionnement. L'alternative la plus probable d'importation de pétrole brut semble être le Mexique. C'est pourquoi cet article cherche à evaluer le potentiel des champs pétrolifères mexicains, au cours de cette décennie, et étudie lesfacteurs qui peuvent inftuencer la politique d'exportation pétrolière de ce pays. L'étude louche aussi la capacité de production et la politique d'exportation du Vénezuéla qui, croit-on, dans les prochaines années, ne sera pas en mesure d'exporter d'aussi grandes quantités de pétrole brut au Canada qu'il ne le fait présentement.

Hiv Aids

The effects of a translated text are notoriously hard to trace and establish. However, in the case of The Three Amigos, a series of short public service announcements on HIV/AIDS prevention that feature three comic figures (animated condoms) and accompany them through numerous adventures in 50 languages, the effects have been hugely successful–measurable in numbers of condoms sold! This article studies some of the translation problems posed by this Canadian production, and examines aspects of the Anglo-American source culture that are now hampering the distribution of this highly successful work. It thus positions translation dissemination as an issue related to source culture policies and politics that may play a bigger role in translation “effects” than a felicitous translation. Keywords: translating HIV/AIDS discourse, translating animation, translating wordplay and jokes, translation and source culture politics.

Phylogenetic Affinities

The Capromyidae (hutias) are endemic rodents of the Caribbean and represent a model of dispersal for non-flying mammals in the Greater Antilles. This family has experienced severe extinctions during the Holocene and its phylogenetic affinities with respect to other caviomorph relatives are still debated as morphological and molecular data disagree. We used target enrichment and next-generation sequencing of mitochondrial and nuclear genes to infer the phylogenetic relationships of hutias, estimate their divergence ages, and understand their mode of dispersal in the Greater Antilles. We found that Capromyidae are nested within Echimyidae (spiny rats) and should be considered a subfamily thereof. We estimated that the split between hutias and Atlantic Forest spiny rats occurred 16.5 (14.8–18.2) million years ago (Ma), which is more recent than the GAARlandia land bridge hypothesis (34–35 Ma). This would suggest that during the Early Miocene, an echimyid-like ancestor colonized the Greater Antilles from an eastern South American source population via rafting. The basal divergence of the Hispaniolan Plagiodontia provides further support for a vicariant separation between Hispaniolan and western islands (Bahamas, Cuba, Jamaica) hutias. Recent divergences among these western hutias suggest Plio-Pleistocene dispersal waves associated with glacial cycles.

New U–Pb ages for late Precambrian volcanic and associated plutonic units in the Mira (Avalon) terrane of southeastern Cape Breton Island indicate that volcanic suites were erupted over a span of at least 100 Ma. The oldest dated rock is a quartz–feldspar rhyodacitic porphyry from the unit that hosts the Mindamar Zn–Pb–Cu–Ag–Au deposit in the Stirling belt, which has an age of [Formula: see text]. The most widespread volcanism and plutonism occurred at ca. 620 Ma in the East Bay Hills and Coxheath Hills belts, and probably the Sporting Mountain belt, as indicated by U–Pb ages and U–Pb maximum ages for rhyolite flows and U–Pb and Ar–Ar ages of crosscutting plutons, as well as stratigraphic constraints. Younger volcanic rocks occur in the Coastal belt, from which a rhyodacitic crystal tuff is dated at [Formula: see text] and a pluton is dated at 574 ± 3 Ma. A rhyolite flow from the contiguous Main-à-Dieu sequence yields a maximum age of ca. 563 Ma, and a minimum age for this sequence is indicated by overlying latest Precambrian to Cambrian fossiliferous sedimentary rocks. Middle Devonian plutonism in the Mira terrane is confirmed by an age of [Formula: see text] from the Lower St. Esprit granodiorite in the Coastal belt. The range of ages of volcanic and plutonic rocks in Mira terrane is similar to that in other parts of Avalon terrane in eastern Newfoundland and southern New Brunswick. Many of the dated rocks contain xenocrystic zircons of Middle Proterozoic ages which suggest a South American source.

Abstract. We present a Rare Earth Elements (REE) record at decadal resolution determined in the EPICA ice core drilled in Dronning Maud Land (EDML) in the Atlantic Sector of the East Antarctic Plateau, covering the transition from the last glacial age (LGA) to the early Holocene (26 600–7500 yr BP). Additionally, samples from potential source areas (PSAs) for Antarctic dust were analysed for their REE characteristics. The dust provenance is discussed by comparing the REE fingerprints in the ice core and the PSAs samples. We find a shift in REE composition at 15 200 yr BP in the ice core samples. Before 15 200 yr BP, the dust composition is very uniform and its provenance was likely to be dominated by a South American source. After 15 200 yr BP, multiple sources such as Australia and New Zealand become relatively more important, albeit South America is possibly still an important dust supplier. A similar change in the dust characteristics was observed in the EPICA Dome C ice core at around ~15 000 yr BP. A return to more glacial dust characteristics between ~8300 and ~7500 yr BP, as observed in the EPICA Dome C core, could not be observed in the EDML core. Consequently, the dust provenance at the two sites must have been different at that time.
