Molecular assessment of a large portion of traditional cyanobacterial taxa has been hindered by the failure to isolate and grow them in culture. In this study, we developed an optimized protocol for single cell/filament isolation and 16S rRNA gene sequencing of terrestrial cyanobacteria with large mucilaginous sheaths, and applied it to determine the phylogenetic position of typical members of the genera Petalonema and Stigonema. A methodology based on a glass-capillary isolation technique and a semi-nested PCR protocol enabled reliable sequencing of the 16S rRNA gene from all samples analyzed. Ten samples covering seven species of Stigonema from Europe, North and Central America, and Hawaii, and the type species of Petalonema from Slovakia were sequenced. Contrary to some previous studies, which proposed a relationship with heteropolar nostocalean cyanobacteria, Petalonema appeared to belong to the family Scytonemataceae. Analysis of Stigonema specimens recovered a unique coherent phylogenetic cluster, substantially broadening our knowledge of the molecular diversity within this genus. Neither the uni- to biseriate species nor the multiseriate species formed monophyletic subclusters within the genus. Typical multiseriate species of Stigonema clustered in a phylogenetic branch derived from uni- to biseriate S. ocellatum Thuret ex Bornet & Flahault in our analysis, suggesting that species with more complex thalli may have evolved from the more simple ones. We propose the technique tested in this study as a promising tool for a future revision of the molecular taxonomy in cyanobacteria. [less ▲]

Turbulent CO2 exchanges over a degraded woodland were measured during 17 months (from November 2005 to March 2007) by an eddy-covariance system at Nangatchori in the northern part of Benin, West Africa. The site (Lat 9.65°N, Long 1.74°E, Alt: 432 m), under a Sudanian climate, is one of the sites that were equipped in the framework of the international AMMA-CATH program. The site was highly disturbed during preceding years by illegal tree logging, agricultural activities, cattle pasture, and bushfire. The footprint area is mainly formed by herbs and crops with some sparse shrubs and trees. Fluxes data were completed during the same period by meteorological measurements made at the Nalohou site located approximately 20 km from Nangatchori, and by an inventory of dominating species on 1km2 area around the tower during the wet season. Fluxes response to climatic variables was analyzed. The annual drought and moisture cycle was found to be the main controlling factor of the ecosystem dynamics. A very clear response of CO2 fluxes to PPFD appears, but is different according to seasons. During wet season, CO2 uptake increases with increasing PPFD following a typical curvilinear function and saturates for high PPFD (PPFD > 1000 µmol m-2 s-1), while during dry season, a very weak linear response of CO2 fluxes was observed. No clear dependency of the total ecosystem respiration on temperature was observed. At an annual scale (from November 1st 2005 to October 31st 2006), net carbon sequestered by the ecosystem was 18 +- 5 g C m-2. Finally, with respect to the water use the ecosystem appeared to be more efficient during morning and wet season than during afternoon and dry period. [less ▲]

Les récits anticipant des sociétés futures sous oppression ou sur le déclin sont régulièrement confondus sous les appellations non synonymiques de "dystopie", "anti-utopie" et "contre-utopie". Ces appariements dénotent une indécision significative à propos de tout un pan de la tradition littéraire de l’utopie. Qu’on le considère comme le double inversé ou la face cachée de l’utopie, le récit d’anticipation négatif présente au moins un invariant structurel : il développe l’histoire fictive d’une communauté dont l’organisation et les bases sociales sont menacées, fragilisées, détruites. Le présent parcours dans une fraction de la littérature française publiée entre 1840 et 1930 propose une mise au point terminologique et quelques balises formelles pour la (re)lecture du récit d’anticipation sociale négatif, dont il s’agit de souligner la cohérence et les spécificités.

Very often roads that are continuously built through Amazonia are thought to mechanically and irreversibly induce colonisation, deforestation and environmental and cultural degradation. This paper provides a detailed case study questioning this taken-for-granted idea. It concerns the Pilón Lajas (Bolivia) and shows that the road gets irreversible only through the interplay between development framing and conservation framing as both define road and spaces, and through the interactions these framings induce between actors that refer to them. Road agency only performs by reciprocal relations that actors develop to stabilise their own practices around roads. Indigenous people, quartered between dilution in interculturality and domination bay conservation, are trying to reconcile autonomy and development by skipping between these frameworks. [less ▲]

Crop residues and plant cover represent a pool of organic matter that can be used either to restore organic matter in soils, and therefore maintain soil fertility, or that can be valorized outside of the field (e.g. energy production). However, it is crucial that the exportation of residues is not done to the detriment of the system sustainability. Three long term experiments have been settled in the loamy region in Belgium. All of them are designed to study the effect of residues management by several tillage systems (conventional plowing versus reduced tillage) on the whole soil-water-plant system. SOLRESIDUS is a field experiment where we study the impact of crop residue management while in SOLCOUVERT and SOLCOUVERT-BIS, we study the impact of cover crop management. SOLRESIDUS was started in 2008. In this field, four contrasted crop residues managements are tested in order to contrast as much as possible the responses from the soil-water plant system. Two practices characterize the four modalities: soil tillage (ploughing at 25 cm depth or reduce tillage at 10 cm max) and residue management (exportation or restitution). SOLCOUVERT and SOLCOUVERT-BIS were started in 2012 and 2013 respectively. In those fields cover crop management is also diverse: destruction of the cover crop by winter ploughing, spring ploughing, strip tillage (with a chemical destruction if needed) or shallow tillage (with a decompaction before cover crop sowing). Although although the overall project aims at studying the impact of management on the whole soil-water-plant system, here we will only present the results concerning crop production (sugar beet) in SOLCOUVERT experiments. The presented data will include germination rate, crop development (biomass quantification and BBCH stages) weeds population, disease occurrence, pest occurrences, nitrogen uptake by plants, quality and quantity of harvested products.   [less ▲]

The morphologies of the ultraviolet auroral emissions on the giant gas planets, Jupiter and Saturn, have conveniently been described with combinations of a restricted number of basic components. Although this simplified view is very handy for a gross depiction of the giant planets’ aurorae, it fails to scrutinize the diversity and the dynamics of the actual features that are regularly observed with the available ultraviolet imagers and spectrographs. In the present review, the typical morphologies of Jupiter and Saturn’s aurorae are represented with an updated and more accurate set of components. The use of sketches, rather than images, makes it possible to compile all these components in a single view and to put aside ultraviolet imaging technical issues that are blurring the emission sources, thus preventing one from disentangling the different auroral signatures. The ionospheric and magnetospheric processes to which these auroral features allude can then be more easily accounted. In addition, the use of components of the same kind for both planets may help to put forward similarities and differences between Jupiter and Saturn. The case of the ice giants Uranus and Neptune is much less compelling since their weak auroral emissions are very poorly documented and one can only speculate about their origin. This review presents a current perspective that will inevitably evolve in the future, especially with upcoming observing campaigns and forthcoming missions like Juno. [less ▲]

Hypophosphatemia is defined by a serum phosphate level lower than 0.8 mmol/l. If hypophosphatemia is chronically maintained, it is associated with muscular, osteous, neurological or cardio-respiratory disorders. We describe a patient with isolated hypophosphatemia, detail the mechanisms of phosphate homeostasis, and envisage the differential diagnosis of hypophosphatemia. Furthermore, we propose a sequential decisional algorithm based on basic biological tests and few complementary investigations. Treatment options are reviewed. [less ▲]

A case of pathological hip fracture associated with an epithelioid hemangioma is reported. Epithelioid hemangioma is a benign tumor, rarely localized in a bone. When the tumor is found on the skeleton, it generally involves a long bone. X-ray does not permit the differenciation of epithelioid hemangioma from other,malignant, vascular tumors. Therefore,the diagnosis requires surgery. Although no consensus treatment guidelines exist, the curettage – filling is most often proposed. [less ▲]

L’Angleterre constitue le troisième système éducatif européen retenu dans le cadre de la recherche 123 pour repenser les formations liées aux fonctions d’accueil, d’encadrement et de direction dans le secteur de l’enfance en Fédération Wallonie-Bruxelles (FWB). Il s'agit d'un pays européen où les enjeux de professionnalisation des fonctions d’accueil et d’encadrement ont été affirmés de manière récente avec, dès la fin des années nonante, une volonté politique de parvenir à un système de formation intégré. L’objectif était de parvenir à constituer des réseaux de professionnel-le-s de l’enfance dans lesquels se retrouveraient des professionnel-le-s de différents secteurs (accueillant-e-s, enseignant-e-s, travailleurs/-euses de la santé...) prenant en charge des enfants et leur famille. Un noyau commun définissant des compétences centrales nécessitant à la fois des aptitudes et des savoirs pour travailler auprès des enfants et de leur famille traverse ces formations. Cette volonté politique de revaloriser l’ensemble du secteur de l’enfance et d’augmenter le niveau global de formation des professionnel-le-s est associée au développement d’une offre d’accueil de qualité, avec notamment la création de nombreux centres intégrés comme celui du centre de Penn Green (Pascal & Bertram, 2010). Une série de réformes et d’innovations ont été initiées pour professionnaliser des personnes sans qualification, notamment grâce à des systèmes qualifiants combinant valorisation des acquis de l’expérience et formation en alternance (Lumsden, 2012a). Parmi les réformes importantes, citons aussi l’extension du curriculum national au secteur de la petite enfance, guidant désormais les pratiques des professionnel-le-s prenant en charge les enfants de 0 à 5 ans (Early Years Foundation Stage : Department for Education, 2014).
