Du fait de sa position stratégique entre l’Afrique du Nord et l’Afrique subsaharienne, le Niger est une terre d’intense mobilité par le départ et le transit de nombreux migrants dont le flux venait de tous les pays de l’Afrique de l’Ouest. Le contexte géopolitique actuellement dominé par l’insécurité dans la partie Est du pays et le nord du Nigeria voisin (guerre imposée par la nébuleuse Boko Haram) ; et l’instabilité des pays frontaliers à l’Ouest (Mali) et au Nord (Libye) poussent les populations à chercher refuge en migrant massivement (plus de 60% des migrants en direction du Maghreb et l’Europe passent par le Niger selon l’Organisation Internationale pour les Migrations) et irrégulièrement vers les grandes villes minières du nord du Niger (Agadez, Arlit, Djado et Dirkou) qui sont les portes d’accès au pays de l’Afrique du Nord et ensuite à la méditerranée afin d’atteindre les pays européens. A tous ces problèmes sécuritaires, s’ajoute le problème d’insécurité alimentaire et foncière qui oblige les populations rurales comme celles de la région de Tahoua à migrer pour un exode temporaire ou saisonnier qui finira par une migration de longue durée à force de prendre goût à l’aventure. Les ruraux qui font face aux déficits cycliques imposés par le changement climatique vont à la recherche du mieux-être et du complément alimentaire des ménages. Cet article traite de l’exode qui sera considéré comme une migration locale et en même temps une initiation à la migration régionale et intercontinentale. Il ressortira les impacts socio-économiques de l’exode agissant sur les ménages dans la région de Tahoua au Niger. [less ▲]

The formation of a global and complex episodic memory requires memory for single units of information of the target event but also binding these elements together. This binding capacity diminishes in healthy aging leading to a so-called associative memory deficit. Interestingly, when support is provided during encoding thanks to semantic prior-knowledge (e.g., semantically related word pairs), this associative deficit can be alleviated. The aim of the present review is to summarize the current literature about the influence of prior-knowledge on associative memory performance in healthy aging. Through an analysis of the procedures that have been used in associative memory studies, we suggest two factors that appear to modulate the impact of prior knowledge on older adults’ associative memory. First, the way word pairs are recombined from the encoding to the retrieval phase is the main factor that has to be taken into account. Conditions that promote recall-to-reject discrimination processes lead to similar performance in older compared to younger adults, whereas conditions that require recollection discrimination lead to an age-related decline. Second, the nature of the semantic relations involved in the prior-knowledge support may influence older adults’ performance by modulating the contribution of recollection and familiarity to recognition. Indeed, categorical semantic relations engage both recollection and familiarity-based discrimination, whereas thematic relations allow participants to rely on familiarity-based discrimination only. This latest observation is crucial when one considers recollection as a declining process, in contrast to familiarity, which remains spared in healthy aging. Therefore, future studies should explore the propensity of other semantic relations to alleviate the age-related associative memory decline. [less ▲]

Despite the increasing need to understand factors shaping community assembly, few studies have simultaneously explored the influence of niche-based and phylogenetic processes. Here, we investigate the relationships between diet, habitat and social behaviour in damselfishes (Pomacentridae) collected in 2014 at Moorea Island (17°30′S, 149°50′W), French Polynesia. Isotope ratios of carbon and nitrogen, in association with stomach contents, delineate three trophic groups: pelagic feeders consuming zooplankton, benthic feeders mainly grazing on algae and an intermediate group feeding on prey from the whole bentho-pelagic compartment. Sulphur isotope ratios indicate segregation between species of the outer reef mostly depending on oceanic input of zooplankton and the lagoonal species relying on locally produced resources or even on terrestrial supply. We demonstrate a tight association between dietary specializations, habitat characteristics and social behaviours, and these correlations are further confirmed by integrating the phylogeny of Pomacentridae. We also provide evidence of phylogenetic conservatism for the stomach content and the habitat–behaviour characters. However, the isotopic trait is evolutionarily more labile probably because it thoroughly depicts the ecological niche of species. To summarize, pelagic feeders (mainly from the Chrominae) usually form shoals in areas close to the open ocean at a maximum depth of 20 m. Benthic feeders (well represented in the Stegastinae) are ubiquitous, solitary and mostly territorial species found at various depths. The intermediate group includes gregarious species from three subfamilies that forage in the lagoon usually above 12 m depth. Overall, we give insight into processes that have structured the damselfish community in Moorea. [less ▲]

We present digital holographic interferometry in the long-wave infrared for monitoring the deformation under cryogenic conditions of a segmented focal plane array (FPA) to be used in a space mission. The long wavelength was chosen for its ability to allow measurement of displacements 20 times larger than DHI in the visible and which were foreseen with the test object under large temperature variations. The latter is a mosaic of 4×4 detectors assembled on a frame. DHI was required to assess the global deformation of the assembly, the deformation of each detector, and piston movements of each of them with respect to their neighbors. For that reason we incorporated the temporal phase unwrapping by capturing a sufficiently high number of holograms between which the phase does not undergo large variations. At last, since the specimen exhibits specular reflectivity at that wavelength, it is illuminated by means of a reflective diffuser. [less ▲]

Polymers with repeating phosphoester linkages in the backbone are biodegradable materials that emerge as a promising class of novel biomaterials, especially in the field of drug delivery systems. In contrast to aliphatic polyesters, the pentavalency of the phosphorus atom offers a large diversity of structures and as a consequence a wide range of properties for these mate- rials. In this paper, it is focused on the synthesis of well-defined polyphosphoesters (PPEs) by organocatalyzed ring-opening polymerization, improving the functionalities by combination with click reactions, degrada- tion of functional PPEs and their cytotoxicity, and inputs for applications in drug delivery.

327 fleas were collected in the fur of small mammals from Py and Mantet (Pyrénées- Orientales). Fiftheen species were identified with Leptopsylla taschenbergi amitina as the most common (42% of catches) and Ctenophthalmus spp. were slightly less common (25%) (C. baeticus arvernus and C. nobilis dobyi). These fleas were found in all stations from the bridge of the Rotja valley (900 m) to the pass of Mantet (1780 m). Three rare species were identified: Amphipsylla sibirica sepifera (2 ex.) on the pass of Mantet (1780 m), first time on the north side of the Pyrenees, Callopsylla saxatilis at Collada Verde (2320m) and Amalareus penicilliger pyrenaicus at the pass of Mantet, the screes of Mantet (1615 m) and Collada Verde.

The efficiency and effectiveness of child safety interventions are determined by the quality of the implementation process. This multinational European study aimed to identify facilitators and barriers for the three phases of implementation: adoption, implementation and monitoring (AIM process). Twenty-seven participants from across the WHO European Region were invited to provide case studies of child safety interventions from their country. Cases were selected by the authors to ensure broad coverage of injury issues, age groups and governance level of implementation (eg, national, regional or local). Each participant presented their case and provided a written account according to a standardised template. Presentations and question and answer sessions were recorded. The presentation slides, written accounts and the notes taken during the workshops were analysed using thematic content analysis to elicit facilitators and barriers. Twenty-six cases (from 26 different countries) were presented and analysed. Facilitators and barriers were identified within eight general themes, applicable across the AIM process: management and collaboration; resources; leadership; nature of the intervention; political, social and cultural environment; visibility; nature of the injury problem and analysis and interpretation. The importance of the quality of the implementation process for intervention effectiveness, coupled with limited resources for child safety makes it more difficult to achieve successful actions. The findings of this study, divided by phase of the AIM process, provide practitioners with practical suggestions, where proactive planning might help increase the likelihood of effective implementation.

Neurogenesis in the dentate gyrus is sensitive to endogenous and exogenous factors that influence hippocampal function. Ongoing neurogenesis and the integration of these new neurons throughout life thus may provide a sensitive indicator of environmental stress. We examined the effects of Aroclor 1254 (A1254), a mixture of polychlorinated biphenyls (PCBs), on the development and function of newly generated dentate granule cells. Early exposure to A1254 has been associated with learning impairment in children, suggesting potential impact on the development of hippocampus and/or cortical circuits. Oral A1254 (from the 6th day of gestation to postnatal day 21) produced the expected increase in PCB levels in brain at postnatal day 21, which persisted at lower levels into adulthood. A1254 did not affect the proliferation or survival of newborn neurons in immature animals nor did it cause overt changes in neuronal morphology. However, A1254 occluded the normal developmental increase in sEPSC frequency in the third post-mitotic week without altering the average sEPSC amplitude. Our results suggest that early exposure to PCBs can disrupt excitatory synaptic function during a period of active synaptogenesis, and thus could contribute to the cognitive effects noted in children exposed to PCBs.

Seagrass meadows are highly productive habitats that can act as “blue carbon sinks” in coastal ecosystems by facilitating sedimentation and trapping particles. However, the magnitude and occurrence of these effects may be species and density dependent. The present study is the first estimation of seagrass sediment carbon sink in the temperate Zostera marina beds in the Baltic Sea. Several descriptors of organic matter characteristics, along with possible organic matter sources in the sediment were compared at vegetated and unvegetated bottoms. The 210Pb dating of the sediment has been used for accumulation rate assessment. The photopigments and POC concentrations in sediments were higher in vegetated bottoms. The SIAR (Stable Isotopes in R) mixing model based on nitrogen and carbon stable isotope values, indicated that higher percentages of organic matter originated from seagrass production in vegetated sediments (40–45%) compared to unvegetated ones (5–21%). The carbon stock in the upper 10 cm of the vegetated sediments ranged from 50.2 ± 2.2 to 228.0 ± 11.6 (g m−2), whereas the annual C accumulation amount from 0.84 ± 0.2 to 3.85 ± 1.2 (g m−2 yr−1). Our study shows that even the relatively weakly developed vegetation of the small temperate seagrass species enhance organic carbon concentration in the sediments. Estimated carbon stock was much lower than those reported for most of the seagrass meadows elsewhere, and the carbon burial rate was the lowest ever reported. Evidently, the global calculations of sediment carbon stock should be reconsidered by taking into account density and species-related variability. [less ▲]
