Article Reference Historical management of equine resources in France from the Iron Age to the Modern Period
Alongside horses, donkeys and their first-generation hybrids represent members of the Equidae family known for their social, economic and symbolic importance in protohistoric and historical France. However, their relative importance and their respective roles in different regions and time periods are difficult to assess based on textual, iconographic and archaeological evidence. This is both due to incomplete, partial and scattered historical sources and difficulties to accurately assign fragmentary archaeological remains at the proper taxonomic level. DNA- based methods, however, allow for a robust identification of the taxonomic status of ancient equine osseous material from minimal sequence data. Here, we leveraged shallow ancient DNA sequencing and the dedicated Zonkey computational pipeline to obtain the first baseline distribution for horses, mules and donkeys in France from the Iron Age to the Modern period. Our collection includes a total of 873 ancient specimens spanning 128 ubiquitous and the most dominant species identified, our dataset reveals the importance of mule breeding during Roman times, especially between the 1st and 3rd centuries CE (Common Era), where they represented between 20.0% and 34.2% of equine assemblages. In contrast, donkeys were almost absent from northern France as-semblages during the whole Roman period, but replaced mules in rural and urban commercial and economic centers from the early Middle Ages. Our work also identified donkeys of exceptional size during Late Antiquity, which calls for a deep reassessment of the true morphological space of past equine species. This study confirmed the general preference toward horses throughout all time periods investigated but revealed dynamic manage-ment strategies leveraging the whole breadth of equine resources in various social, geographic and temporal contexts.

We report a case of predation by an adult Eastern Black-and-Yellow Tree Snake Toxicodryas vexator (Serpentes : Colubridae) on a juvenile Lord Derby's Scaly-tailed Squirrel Anomalurus derbianus (Rodentia : Anomaluridae) in Yangambi, Tshopo Province, Democratic Republic of the Congo. This is the first documented interaction between these two species.

Article Reference Skeleton of a new owl from the early Eocene of North America (Aves, Strigiformes) with an accipitrid-like foot morphology
We describe a partial skeleton of a large-sized owl from Wasatchian strata of the Willwood Formation (Wyoming, U.S.A.). The holotype of Primoptynx poliotauros, gen. et sp. nov., includes all major postcranial bones and is one of the most substantial Paleogene records of the Strigiformes. The fossil shows that owls exhibited a considerable morphological diversity in the early Eocene of North America and occupied disparate ecological niches. As in the protostrigid taxon Minerva from the late early to early middle Eocene of North America, but unlike in extant owls, the ungual phalanges of the hallux and the second toe of the new species are distinctly larger than those of the other toes. Primoptynx poliotauros gen. et sp. nov., however, does not exhibit the derived tibiotarsus morphology of the Protostrigidae. Even though the new species may well be a stem group representative of protostrigid owls, current data do not allow an unambiguous phylogenetic placement. Concerning the size of the ungual phalanges, the feet of P. poliotauros correspond to those of extant hawks and allies (Accipitridae). We therefore hypothesize that it used its feet to dispatch prey items in a hawk-like manner, whereas extant owls kill prey with their beak. Primoptynx and protostrigid owls were possibly specialized in foraging on prey items that required an accipitrid-like killing strategy, such as larger-sized or more defensive mammals. The extinction of these peculiar owls may have been related to the radiation of accipitrid diurnal birds of prey, which appear to have diversified in the late Eocene and early Oligocene.

Article Reference Ancient DNA reveals lack of postglacial habitat tracking in the arctic fox
How species respond to an increased availability of habitat, for example at the end of the last glaciation, has been well established. In contrast, little is known about the opposite process, when the amount of habitat decreases. The hypothesis of habitat tracking predicts that species should be able to track both increases and decreases in habitat availability. The alternative hypothesis is that populations outside refugia become extinct during periods of unsuitable climate. To test these hypotheses, we used ancient DNA techniques to examine genetic variation in the arctic fox (Alopex lagopus) through an expansion/contraction cycle. The results show that the arctic fox in midlatitude Europe became extinct at the end of the Pleistocene and did not track the habitat when it shifted to the north. Instead, a high genetic similarity between the extant populations in Scandinavia and Siberia suggests an eastern origin for the Scandinavian population at the end of the last glaciation. These results provide new insights into how species respond to climate change, since they suggest that populations are unable to track decreases in habitat availability. This implies that arctic species may be particularly vulnerable to increases in global temperatures. © 2007 by The National Academy of Sciences of the USA.

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.
