Article Reference Archaeozoological evidence for the former presence of spotted-necked otter ( Lutra maculicollis ) in Egypt
A description is given of the skeletal remains of otter discovered at the Late Palaeolithic fishing sites Makhadma 2 and 4. This is the second archaeozoological find of otter in Egypt and the first one that allows an identification at species level. The possible reasons for the rarity of otter remains in sites along the Egyptian Nile are discussed as well as the possible causes for the present-day local extinction of the species. The consequences of these bone finds for the interpretation of animal depictions and statuettes in ancient Egyptian art are briefly mentioned.

Article Reference The genus Aphanius Nardo 1827 (Pisces: Cyprinodontidae) in Turkey
The Turkish species of the Cyprinodontiform genus Aphanius Nardo 1827 are described. The naming used follows Wildekamp (1993) (1) as the latest available revision. Information is given on morphology, sexual dimorphism, colouration and distribution, as well as remarks on taxonomy, nomenclature, distribution, variability and conservation. Comments are given on the Lazara (1995) (2) revalidation of Lebias as a distinct genus. It is shown that Valenciennes (1846) (3) is the first revisor of Lebias, and not Lazara, and that Aphanius should be maintained as a genus. The taxon Aphanius chantrei (Galliard 1895) is regarded as a junior synonym of Aphanius danfordii (Boulenger 1890), a lectotype for A. danfordii is designated and a more detailed type locality is given.

Article Reference Macrocranion germonprae n. sp., insectivore proche de la limite Paléocène-Eocène en Belgique
La nouvelle espèce Macrocranion germonpreae du Membre de Dormaal (Groupe de Landen, Belgique) est décrite sur la base de dents jugales isolées. Cet insectivore érinacéomorphe est comparé aux autres espèces du genre Macrocranion d'Europe et d'AmCrique du Nord. M. germonpreae possède les caractères morphologiques d'un Dormaaliinae primitif.

Article Reference Diversity of the adapisoriculid mammals from the early Palaeocene of Hainin, Belgium
Adapisoriculidae are an enigmatic group of small mammals known from the late Cretaceous of India, and from the early Palaeocene to early Eocene of Europe and Africa. Based on their primitive dental morphology, they have been classified as didelphids, nyctitheriids, leptictids, mixodectids, tupaiids, and palaeoryctids. While the latest hypothesis based on dental morphology suggests an affinity with Lipotyphla, postcranial remains indicate a close relationship with Euarchonta. Here, we present new adapisoriculid dental remains from the early Palaeocene locality of Hainin (Belgium). Adapisoriculidae are particularly abundant in Hainin, where they represent about one third of the mammalian fauna, offering new insights into both their specific and generic phylogenetic interrelationships. We describe three new species (Afrodon gheerbranti sp. nov., Bustylus folieae sp. nov. and Proremiculus lagnauxi gen. et sp. nov.) and document the previously unknown lower dentition of Bustylus marandati. The diversity of dental morphologies observed in the Hainin fauna suggests different interrelationships than previously suggested. In particular, the genus Proremiculus is considered morphologically intermediate between Afrodon and Remiculus, and the latter is no longer recognised as the sister group of Adapisoriculus. Although the highest diversity of adapisoriculids occurs in Europe, the oldest and most primitive members of the family were found in India and Africa, respectively. The geographic origin of the family could thus be located in any of these three continents, depending on the importance attributed to each of these factors. The coexistence of primitive and derived adapisoriculids at Hainin might indicate a very quick diversification in Europe, probably starting around the K−T boundary.

Article Reference Repeated unidirectional introgression of nuclear and mitochondrial DNA between four congeneric Tanganyikan cichlids.
With an increasing number of reported cases of hybridization and introgression, interspecific gene flow between animals has recently become a widely accepted and broadly studied phenomenon. In this study, we examine patterns of hybridization and introgression in Ophthalmotilapia spp., a genus of cichlid fish from Lake Tanganyika, using mitochondrial and nuclear DNA from all four species in the genus and including specimens from over 800 km of shoreline. These four species have very different, partially overlapping distribution ranges, thus allowing us to study in detail patterns of gene flow between sympatric and allopatric populations of the different species. We show that a significant proportion of individuals of the lake-wide distributed O. nasuta carry mitochondrial and/or nuclear DNA typical of other Ophthalmotilapia species. Strikingly, all such individuals were found in populations living in sympatry with each of the other Ophthalmotilapia species, strongly suggesting that this pattern originated by repeated and independent episodes of genetic exchange in different parts of the lake, with unidirectional introgression occurring into O. nasuta. Our analysis rejects the hypotheses that unidirectional introgression is caused by natural selection favoring heterospecific DNA, by skewed abundances of Ophthalmotilapia species or by hybridization events occurring during a putative spatial expansion in O. nasuta. Instead, cytonuclear incompatibilities or asymmetric behavioral reproductive isolation seem to have driven repeated, unidirectional introgression of nuclear and mitochondrial DNA into O. nasuta in different parts of the lake.
