Article Reference Mitochondrial DNA sequence from an enigmatic gorilla population (Gorilla gorilla uellensis)
Although today gorillas are found in only two widely separate, discontinuous western and eastern African populations, rumors of the existence of an additional gorilla population in central Africa have inspired recent unsuccessful field expeditions in search of the "mystery ape" termed Gorilla gorilla uellensis. Such a gorilla population would have considerable conservation and scientific interest, and would presumably have descended from a population of gorillas that was thought to exist until the end of the 19th century on the Uele River in the current-day Democratic Republic of Congo. However, the sole evidence for the existence of these gorillas is three skulls and one mandible brought to the Royal Museum for Central Africa (Tervuren, Belgium) in 1898. We determined a mitochondrial DNA sequence from one of these specimens and compared it to sequences from other gorillas. Contrary to expectations, the sequence obtained did not exhibit the phylogenetic distinctiveness typical of a representative of a peripheral isolated population. Rather, the results suggest a scenario in which the museum specimens did not originally derive from the northern Congo, but were brought from the area of current distribution of western gorillas to that location; the subsequent discovery and collection of the specimens there gave rise to the false inference of a local gorilla population.

Article Reference Mitogenomic characterization and systematic placement of the Congo blind barb Caecobarbus geertsii (Cypriniformes: Cyprinidae)
This study presents the first complete mitochondrial genome (mitogenome) of Caecobarbus geertsii, the Congo blind barb, a cave-dwelling, CITES-protected, cyprinid fish endemic to the Lower Congo basin (DRC). The length of the circular mitogenome is 16,565 base pairs. The 13 protein coding genes, 2 ribosomal RNA genes and 22 transfer RNA genes are similar in position and direction to those of other members of the family Cyprinidae. Phylogenetic analyses including 28 complete mitogenomes from representatives of the subfamily Smiliogastrinae (Cyprinidae), showed that Caecobarbus was nested within a clade including representatives of the genus Enteromius. The data presented in this study provide information on the molecular identification and classification of this threatened species. The results further suggest the need for a taxonomic revision of the genus Enteromius.

Article Reference Mobility and origin of camels in the Roman Empire through serial stable carbon and oxygen isotopes variations in tooth enamel
Although camels are not indigenous to Europe, they have been found at several sites from several Roman provinces dating from the beginning of the 1st century AD onwards. It must have been beneficial to bring them there. Based on finds of remains from juvenile individuals (e.g. from Tanais), it has been suggested that the Romans might have systematically bred camels within Europe. For this study, we took serial samples of the enamel of four camels from European sites (Innsbruck-Wilten, Mamer-Bertrange, Tongeren, and Trier) dating to the 2nd - 4th century AD. We measured the relative abundances of carbon and oxygen isotopes of the carbonate fraction from the tooth enamel. The continuous record of oxygen and carbon isotopic composition of the intra-tooth enamel serial samples reflects the climate and habitat in which an individual lived during the time of tooth mineralization. We used these data to make a rough evaluation of the areas of origin consistent with the relative abundances of the isotopes from the enamel of the camels and attempt to reconstruct their life history and mobility behavior based on the different ecological characteristics of the habitats represented in the isotopic data. Furthermore, the data can function as an additional proxy for species determination, due to the different habitats of Camelus bactrianus and Camelus dromedarius. This work also yields interesting insights on the similarities in the mobility pattern of the camels from Mamer-Bertrange and Trier. In combination with archaeological evidence, it was possible to tentatively connect them with specific military units, i.e. the detachments of the Legio VIII Augusta.

Article Reference Mode de vie et affinités de Paschaterium (Condylarthra, Hyopsodontidae) d'après ses os du tarse
Les os du tarse de Paschatherium dolloi de Dormaal sont décrits et analysCs fonctionnellement. L'astragale possède une trochlée en poulie dissymétrique, une large cupule mediale pour la malléole du tibia, un col court. Le calcanéum a un tubercule péronéen bien développé et distal. Les facettes entre les deux os reflètent leur mobilité relative. L'ensemble des caractères indiquent une locomotion rapide, des mouvements de flexion-extension étendus et de fréquentes rotations du pied. Paschatherium est interprété comme un arboricole de type sciuridé. Les comparaisons effectuées avec le Macrocranion de Dormaal et un Hyopsodus nord-am6ricain montrent: des ressemblances partielles entre les astragales de Paschatherium et Macrocranion, probablement dues à des convergences fonctionnelles; une grande similitude des calcanéums de Paschatherium et Hyopsodus, indiquant probablement leur parenté. Nous confirmons le placement de Paschatherium dans les condylarthres hyopsodontidés. Les diff6rences entre les astragales de Paschatherium et Hyopsodus indiquent une divergence adaptative marquée entre les deux genres. Les ressemblances entre l'astragale de Paschatherium et celui des hyracoïdes nous font spéculer sur un possible scénario adaptatif concernant l'origine de ces derniers, scénario qui va à l'encontre du concept de Pantomesaxonia. Avec d'autres caractères. ces ressemblances pourraient suggérer une parenté des hyopsodontidés et des hyracoïdes (et téthythères).
