Article Reference Evolution of European carnivorous mammal assemblages through the Palaeogene
The rise of Carnivora (Mammalia: Laurasiatheria) is an important evolutionary event that changed the structure of terrestrial ecosystems, starting at the dawn of the Eocene, 56 Mya. This radiation has been mainly analysed in North America, leaving the evolution of carnivoran diversity in other regions of the globe poorly known. To tackle this issue, we review the evolution of terrestrial carnivorous mammal diversity (Mesonychidae, Oxyaenidae, Hyaenodonta and Carnivoramorpha) in Europe. We reveal four episodes of intense faunal turnovers that helped establish the dominance of carnivoramorphans over their main competitors. We also identify two periods of general endemism. The remaining time intervals are characterized by dispersals of new taxa from North America, Asia and Africa. The European Palaeogene carnivorous mammal fauna appears to have been almost constantly in a transient state, strongly influenced by dispersals. Many of the bioevents we highlight for European carnivorous mammals are probably best seen as ecosystem-wide responses to environmental changes. In contrast to the North American record, European hyaenodonts remain more diverse than the carnivoramorphans for the entire Eocene. The replacement of hyaenodonts by carnivoramorphans as the most diverse and dominant predators only occurred after the ‘Grande Coupure’ at 33 Mya, about 16 Myr later than in North America.

Article Reference Evolution of prehistoric fishing in the Nile Valley
The available data are reviewed on ichthyofaunas from prehistoric sites along the Nile in Egypt and Sudanese Nubia. Former fishing practices are reconstructed using information derived from species spectra, reconstructed fish sizes, growth increment analysis and fishing implements. It is demonstrated that fishing was initially practised exclusively on the floodplain and that it was limited to a small number of shallow water taxa during Late Palaeolithic times. From the Epipalaeolithic onwards (ca 10000-8000 bp), fishing was also undertaken in the main Nile whereby the number of exploited species increased. Technological innovations allowing the exploitation of the deeper parts of the main river included nets and fish-hooks as well as improved vessels, permitting the capture of larger species from the open water. It is argued that fish must always have been a staple food because the animals seasonally occurring in large numbers on the floodplain were intensively exploited and because these fish could be easily dried for future consumption. Once the fishing grounds also included the main river, fishing was no longer restricted to the flood season, but could also be carried out when the Nile levels were low. Hence the role of fish in the resource scheduling also changed at the transition of Late Palaeolithic to Epipalaeolithic times.

Inproceedings Reference Evolution of the European mesonychid mammals and theur bearings on the European Paleoecosystems and biostratigraphy
European mesonychids are represented by few specimens found only in late Paleocene and early Eocene localities. Recent field works in Palette and La Borie (Ypresian of France) resulted in the discovery of new mesonychid specimens. Additionally, our review of the mesonychids housed by European scientific institutions allowed establishing the occurrence of Dissacus in Berru (Thanetian) and Sézanne-Broyes (Ypresian). Only the genera Pachyaena and Dissacus are recognized in Europe. Furthermore, two new Dissacus species can be defined from the Ypresian localities of Palette, Sézanne-Broyes and La Borie. We also identified from three localities several postcranial elements that could be referred to Dissacus. The preliminary study of this postcranial material suggests a cursorial locomotion. As a result of our study, we propose a scheme of evolution comprising three phases for these particular mammals in Europe. (1) The mesonychid Dissacus dispersed into Europe during Thanetian, probably from North America; it survived the PETM event and even possibly experienced a dwarfism during this global warming. (2) The very large mesonychid Pachyaena migrated into Europe shortly after the Paleocene–Eocene boundary, but it seems that it did not coexist with Dissacus: it was restricted to Northern Europe, while Dissacus was possibly present at that time only in southern areas. (3) However, Pachyaena rapidly disappeared from the European environments, while Dissacus dispersed subsequently into Northern Europe. These data support the existence of a faunal turnover in Northern Europe shortly after the PETM event: it has been notably proposed for explaining the disappearance from Europe of the carnivorous oxyaenids and hyaenodont sinopines, and their subsequent replacement by taxa from the southern areas. The persistence of Dissacus in Europe shows that size was not the main selective factor during this dramatic period. Dissacus has evolved endemically during Thanetian and Ypresian in Europe where it reached a very large size, especially in southern France and Spain. Due to its size, dental, and locomotor adaptations, Dissacus was probably the top mammal predator in Europe. It survived in Europe after its disappearance from North America, possibly due to its ecologic position and the lack of competitors.

Article Reference Evolutionary history of a dispersal-associated locus across sympatric and allopatric divergent populations of a wing-polymorphic beetle across Atlantic Europe
Studying the evolutionary history of trait divergence, in particular those related to dispersal capacity, is of major interest for the process of local adaptation and metapopulation dynamics. Here, we reconstruct the evolution of different alleles at the nuclear-encoded mitochondrial NADP+-dependent isocitrate dehydrogenase (mtIdh) locus of the ground beetle Pogonus chalceus that are differentially and repeatedly selected in short- and long-winged populations in response to different hydrological regimes at both allopatric and sympatric scales along the Atlantic European coasts. We sequenced 2788 bp of the mtIdh locus spanning a ~7-kb genome region and compared its variation with that of two supposedly neutral genes. mtIdh sequences show (i) monophyletic clustering of the short-winged associated mtIDH-DE haplotypes within the long-winged associated mtIDH-AB haplotypes, (ii) a more than tenfold lower haplotype diversity associated with the mtIDH-DE alleles compared to the mtIDH-AB alleles and (iii) a high number of fixed nucleotide differences between both mtIDH haplotype clusters. Coalescent simulations suggest that this observed sequence variation in the mtIdh locus is most consistent with a singular origin in a partially isolated subpopulation, followed by a relatively recent spread of the mtIDHDE allele in short-winged populations along the Atlantic coast. These results demonstrate that even traits associated with decreased dispersal capacity can rapidly spread and that reuse of adaptive alleles plays an important
