Corresponding author. cosson@supagro.inra.fr; International audience; Multimammate rats (genus Mastomys) are abundant in many regions throughout sub-Saharan Africa, and are of high economical and sanitary importance as agricultural pests as well as reservoir/vectors of human diseases. In pest management and in epidemiological studies, unequivocal species identification of individuals collected in the field is crucial. However, the discrimination among most of the Mastomys species is often difficult, if not impossible, on the basis of external characters. Karyology provides unambiguous specific assignations, but is not suitable for population studies involving large numbers of individuals because it requires fresh material and/or quick transfer from the field to the laboratory. The purpose of this study was to search for molecular markers allowing a clear discrimination of field collected individuals on the basis of ethanol-preserved samples. Using sequences of the cytochrome b region of mitochondrial DNA, two molecular tests based on species-specific primers (test 1) and restriction sites generating species-specific profiles (test 2), were designed and evaluated for species identification on a large number of karyotypically or electrophoretically unambiguously determined individuals. The tests clearly discriminate the four most widespread species. They are easy to perform on a small piece of car or tail taken from live animals, and can probably be adapted to identify museum specimens

International audience; In this study, we re-assess the use of bivalve shells as a proxy of lead pollution. Previous studies have stressed that shells display little variability compared to soft tissues and thus are better for pollution biomonitoring. However, in this manuscript we illustrate that there is large inter- and intra-annual Pb variability between shells of the clam Mercenaria mercenaria collected in North Carolina, USA. Therefore, year to year, as well as intra-annual variations in Pb/Ca ratios should be interpreted with caution. Despite this variability, we were able to obtain an annual Pb chronology from 1949 to 2002 using 11 shells collected at different times which clearly exhibited the late 1970's peak in Pb from leaded gasoline use. This indicates that when enough specimens are pooled together, bivalve shells can be used to reconstruct large, long term changes in environmental Pb concentrations. Our data compare well with other studies of aragonite clams from sites with low regional lead pollution. From this we conclude that the Cape Lookout region of North Carolina has not received extensive pollution over the 1949-2002 period. The Pb concentration in shells growing in the 1949-1976 period was not significantly different from those growing in the 1982-2002 period, although other proxies suggest that the 1949-1976 period should be considerably higher. Therefore, our data suggest that there is still a modern source of Pb in the coastal North Carolina environment.

We examined 13 C values of shallow and deep-water scallop shells as well as 13 C of dissolved inorganic carbon (DIC) from the Bay of Brest in western Brittany. Time series of shell calcite 13 Cd o not reflect seasonal variation in seawater 13 C, but rather show a consistent pattern of decreasing 13 C with age, suggesting a metabolic effect rather than direct environmental control. This 13 C trend reflects an increasing contribution of metabolic CO2 to skeletal carbonate throughout ontogeny, although this respired CO2 does not seem to be the major source of skeletal carbon (contribution of only 10% over the first year of life). We propose a model of this effect that depends on the availability of metabolic carbon relative to the carbon requirements for calcification. A ratio of "respired to precipitated carbon" is calculated, and represents the amount of metabolic carbon available for calcification. Interestingly, this ratio increases throughout ontogeny suggesting a real increase of metabolic carbon utilization into the skeleton relative to carbon from seawater DIC. This ratio allows us to separate two different populations of Pecten maximus of different water depth. It is therefore suggested that shell 13 C might be used to track differences in the metabolic activity of scallops from different populations. Copyright © 2004 Elsevier Ltd

International audience; Biome reconstruction from pollen and plant macrofossil data provides an objective method to reconstruct past vegetation. Biomes for Africa and the Arabian peninsula have been mapped for 6000 years sp and provide a new standard for the evaluation of simulated palaeovegetation distributions. A test using modern pollen data shows the robustness of the biomization method, which is able to predict the major vegetation types with a high confidence level. The application of the procedure to the 6000 years data set (pollen and plant macrofossil analyses) shows systematic differences from the present that are consistent with the numerous previous regional and continental interpretations, while providing a more extensive and more objective basis for such interpretations. Madagascar, eastern, southern and central Africa show only minor changes in terms of biomes, compared to present. Major changes in biome distributions occur north of 15 degrees N, with steppe in many low-elevation sites that are now desert, and temperate xerophytic woods/scrub and warm mixed forest in the Saharan mountains. These shifts in biome distributions, imply significant changes in climate, especially precipitation, between 6000 years and present, reflecting a change in monsoon extent combined with a southward expansion of Mediterranean influence.

International audience; The sex attractant for Phyllonorycter melanosparta (Meyrick, 1912) has been determined as (10E)-dodec-10-en-1-yl acetate and (10E)-dodec-10-en-1-ol combined in a ratio 10:1. The distribution of this species in Eastern Africa is updated and its presence in Kenya is recorded for the first time. We discuss the taxonomic status of P. melanosparta with reference to three character sets: semiochemicals, morphological and molecular characters (DNA barcodes). This combination of characters is also proposed as a new approach to study the diversity and phylogeny of Phyllonorycter in the Afrotropical region.

International audience; - Alpine jades in the European Neolithic - The ANR-funded programmes JADE 1 (2007-2011) and JADE 2 (2013-2017) inves-tigated the production and the extraordinary diffusion of axeheads (large and small) made of Alpine jades on a Europe-wide scale. The phenom-enon began during the middle of the sixth millennium BC and ended over the course of the third millennium BC. The precious jades (jadeitite, om-phacitite and fine-grained eclogite) were exploited at high altitude as well as among the torrent cones of the two Italian Alpine massifs, Mont Viso and Mont Beigua. Two technical traditions of shaping roughouts—one in-volving percussion, the other sawing—supplied networks of contacts that were orientated in different directions. The products travelled over much of Europe, with a few reaching central Europe and the Balkans as far as the Black Sea, moving along routes and at distances up to 1800 km as the crow flies.The authors set out here to explore the complexity of the networks over which the axeheads travelled and to attempt to account for the causes of this spatially extensive phenomenon that endured for nearly three millennia. The importance of elites’ social imagination is the best way to understand the religious sys-tems that were in play: these systems determined that only powerful individu-als were allowed to handle large Alpine axeheads, depositing them in hoards consecrated to the gods. This explanation accounts for the major phase of Al-pine axehead movement that began around 4700 BC with the flow of axeheads towards Brittany and which ended around 3800-3600 BC with the arrival of axeheads in Germany, Britain and Ireland. Our hypothesis thus stands in stark contrast with the commonly-held (and unsubstantiated) view of some geolo-gists that Alpine axeheads were made from flat cobbles taken from torrent beds and that they moved, as ordinary prestige goods, in a ‘down-the-line’ fashion. Our hypothesis offers a new perspective on Neolithic societies in western Eu-rope, seeing them as inegalitarian in nature, with epicentres in Brittany and the Paris Basin. These two regions had a mythology that featured jade axeheads as being male symbols.

National audience; Le matériel poli découvert lors des fouilles du site de Beg ar Loued se limite à vingt-deux objets. Leur examen pétrographique et spectroradiométrique a permis de définir les roches exploitées et dans certains cas de proposer une origine géographique. L'outillage, très fragmenté, est exclusivement réalisé dans des fibrolites. Deux sources continentales de ce matériau ont été mises à profit pour la fabrication des outils. Les pendeloques ont été façonnées dans des roches variées probablement collectées sur estran sous la forme de galets. Une série de petites perles discoïdes a été réalisée dans des roches schisteuses (gneiss et micaschiste) dont l'origine locale laisse peu de doute. Une seule perle achevée est en test coquillier. La répartition de ces objets et leur position stratigraphique vont dans le sens d'une attribution au Néolithique final. Un fragment de fusaïole semble appartenir à l'occupation Bronze ancien du site. Abstract The polished material discovered during the excavations of the site is limited to twenty-two objects. Their petrographic and spectroradiometric allows us to define exploited rocks and in some cases to provide the source of raw materials. Polished stones axes are highly fragmented and exclusively made of fibrolites. Two continental sources of this rock have been exploited for the manufacture of tools. The pendants were shaped in various rock probably collected on foreshore in the form of pebbles. Finally, a serie of small disc beads was performed in schistose rocks (gneiss, schist); their local origin leaves little doubt. Only one finished disc bead is made of shell. The distribution of these objects and their stratigra-phic position are in line with an allocation to the Final Neolithic. Finally, a spindle whorl fragment seems to belong to the Early Bronze Age occupation of the site.

- Abstract
Objectives: The Middle Pleistocene (MP) saw the emergence of new species of hominins: Homo sapiens in Africa, H. neanderthalensis, and possibly Denisovans in Eurasia, whose most recent common ancestor is thought to have lived in Africa around 600 ka ago. However, hominin remains from this period present a wide range of morphological variation making it difficult to securely determine their taxonomic attribution and their phylogenetic position within the Homo genus. This study proposes to reconsider the phenetic relationships between MP hominin fossils in order to clarify evolutionary trends and contacts between the populations they represent., Materials and Methods: We used a Geometric Morphometrics approach to quantify the morphological variation of the calvarium of controversial MP specimens from Africa and Eurasia by using a comparative sample that can be divided into 5 groups: H. ergaster, H. erectus, H. neanderthalensis, and H. sapiens, as well as individuals from current modern human populations. We performed a Generalized Procrustes Analysis, a Principal Component Analysis, and Multinomial Principal Component Logistic Regressions to determine the phenetic affinities of the controversial Middle Pleistocene specimens with the other groups., Results: MP African and Eurasian specimens represent several populations, some of which show strong affinities with H. neanderthalensis in Europe or H. sapiens in Africa, others presenting multiple affinities., Discussion: These MP populations might have contributed to the emergence of these two species in different proportions. This study proposes a new framework for the human evolutionary history during the MP., (© 2024 The Authors. American Journal of Biological Anthropology published by Wiley Periodicals LLC.)

- Abstract
Brachytydeus juanjosei sp. nov., a new species of Neotropical Tydeidae, is illustrated and described from females, males, and a tritonymph collected from the leaves of a native forest tree, Neltuma piurensis (Fabaceae), from Department of Piura in north-western Peru. The new tydeid mite was found all year long, but more frequently observed during spring in high populations (September/December). A key to the known Peruvian species of the subfamily Tydeinae is provided.

- Abstract
A revised classification of Afrotropical Trichopolydesmidae is presented. The fauna presently contains as many as 52 species in six recognized genera, with numerous new transfers/combinations involved: Bactrodesmus Cook, 1896 (3 species, including B. grandis sp. nov. from the Nimba Mountains, Guinea), Eburodesmus Schubart, 1955 (2 species), Hemisphaeroparia Schubart, 1955 (26 species, including one old species, Polydesmus parvulus Porat, 1894, revised from type material and provisionally assigned to Hemisphaeroparia , as well as two new records and two new species from Cameroon: H. longibrachiata sp. nov. and H. avis sp. nov. ), Mecistoparia Brolemann, 1926 (3 species), Physetoparia Brolemann, 1920 (12 species, including P. complexa sp. nov. from the Nimba Mountains, Guinea), and Sphaeroparia Attems, 1909 (6 species). The hitherto enigmatic genus Bactrodesmus is redefined, but the monotypic Trichozonus Carl, 1905 still remains dubious., (Sergei I. Golovatch, Armand Richard Nzoko Fiemapong, Didier VandenSpiegel.)

- Abstract
In addition to one of the two species of Trichopolydesmidae hitherto recorded from Cameroon, Polydesmusintegratus Porat, 1894, which is revised based on type material and shown to represent the genus Hemisphaeroparia Schubart, 1955, comb. n. , 12 new species from the same genus are described from that country: H.zamakoe sp. n. , H.bangoulap sp. n. , H.spiniger sp. n. , H.ongot sp. n. , H.digitifer sp. n. , H.parva sp. n. , H.fusca sp. n. , H.bonakanda sp. n. , H.bamboutos sp. n. , H.subfalcata sp. n. , H.falcata sp. n. and H.mouanko sp. n. A key to all 13 species (of Hemisphaeroparia ) known to occur in Cameroon is presented, and their distributions are mapped. All ten recognizable (but excluding two dubious) Afrotropical genera or subgenera of Trichopolydesmidae are rediagnosed and reclassified, based both on their type species and a presumed scenario of gonopodal evolution. As a result, the number of accepted genera is reduced to five: Sphaeroparia Attems, 1909 (= Megaloparia Brolemann, 1920), Physetoparia Brolemann, 1920 (= Elgonicola Attems, 1939, syn. n. , = Mabocus Chamberlin, 1951, syn. n. , = Heterosphaeroparia Schubart, 1955, syn. n. }, Eburodesmus Schubart, 1955, Mecistoparia Brolemann, 1926 (= Dendrobrachypus Verhoeff, 1941, syn. n. ), and Hemisphaeroparia .

116. Review of the western African millipede genus Diaphorodesmus Silvestri, 1896 (Diplopoda, Polydesmida, Chelodesmidae), with the description of a similar, but new monotypic genus from Cameroon.

- Abstract
The genus Diaphorodesmus is revised and shown to comprise only a single species, Diaphorodesmus dorsicornis (Porat, 1894) by priority, with the only other formal congener, Diaphorodesmus attemsii Verhoeff, 1938, considered as its junior subjective synonym, syn. n. A new monotypic genus, Diaphorodesmoides gen. n., is created to include Diaphorodesmoides lamottei sp. n., from southwestern Cameroon. Both these genera seem to be especially similar in sharing remarkable dorsal horns on metaterga 2-4, a unique synapomorphy in the basically Afrotropical subfamily Prepodesminae, family Chelodesmidae, to which they belong. In contrast to Diaphorodesmus which shows two, increasingly short, paramedian horns on each of metaterga 2-4, the ozopores borne on distinct porosteles, and the gonopod prefemoral process and solenophore less strongly elaborate, Diaphorodesmoides gen. n. has a single, increasingly large, central horn on each of metaterga 2-4, the ozopores opening flush dorsolaterally on the surface of poriferous paraterga, and both the gonopod prefemoral process and solenophore especially complex. The genus Campodesmoides VandenSpiegel, Golovatch & Nzoko Fiemapong, 2015, and its sole, and type, species Campodesmoides corniger VandenSpiegel, Golovatch & Nzoko Fiemapong, 2015, are transferred from Campodesmidae to Chelodesmidae and formally synonymized with Diaphorodesmus and Diaphorodesmus dorsicornis, both syn. n.

- Abstract
The genus Eviulisoma, the largest among Afrotropical Paradoxosomatidae, currently encompasses 36 species or subspecies, including six new from Kenya: Eviulisomangaia sp. n., Eviulisomangaiaorum sp. n., Eviulisomataitaorum sp. n., Eviulisomataita sp. n., Eviulisomakirimeri sp. n. and Eviulisomakakamega sp. n. In addition, Eviulisomaalluaudi Brolemann, 1920 and Eviulisomasilvestre (Carl, 1909) are recorded for the first time beyond their type localities in Kenya and Tanzania, respectively, based on new material from Kenya. A key is given to all ten species of the genus presently reported from Kenya.

Golovatch SI, Geoffroy JJ, and VandenSpiegel D
- Abstract
In the Oriental Region, the large, basically Northern Hemisphere family Trichopolydesmidae is shown to currently comprise 18 genera and 43 species. Based mainly on gonopod structure, all of them, as well as the whole family, are (re)diagnosed, including five new genera and seven new species. These new taxa are keyed, also being the first to be described from Indochina in general and from Vietnam in particular: Aporodesmella gen. n., with three species: A. securiformis sp. n. (the type species), A. similis sp. n. and A. tergalis sp. n., as well as the following four monotypic genera: Deharvengius gen. n., with D. bedosae sp. n., Gonatodesmus gen. n., with G. communicans sp. n., Helicodesmus gen. n., with H. anichkini sp. n., and Monstrodesmus gen. n., with M. flagellifer sp. n. In addition, Cocacolaria hauseri Hoffman, 1987, hitherto known only from New Ireland Island, Papua New Guinea, is redescribed based on material from Vanuatu whence it is recorded for the first time. One of the new genera, Gonatodesmus gen. n., provides a kind of transition or evolutionary bridge between Trichopolydesmidae and Opisotretidae, thus reinforcing the assignment of these two families to the single superfamily Trichopolydesmoidea.
