Description of the subject. In Morocco, expanding agricultural sector under “Morocco Green Plan” will also introduce plant diseases and plant parasitic nematodes (PPN). Soil substrate used in most of the olive nurseries is potentially inhabited by PPN and natural enemies. Objectives. This work assessed the co-occurrence of PPN and nematophagous fungi (NF) in substrates and potential of NF to suppress PPN. Method. The diversity of PPN and NF genera was characterized in 305 substrate samples, isolated from 25 olive nurseries and functional activity (nematicidal and enzymatic) of NF was evaluated. Results. High PPN diversity was detected in the isolated samples and substrates were differentiated by NF activity. Global partition between PPN and NF diversity patterns confirmed prey-predator antagonism. Moreover, PPN-NF patterns depend on the fungal survival (saprophytes vs obligate parasites) and antagonism (predation vs toxicity) processes. However, even the NF strains with maximum fitness (growth, sporulation, enzymatic activity) were not inevitably the most effective against PPN. Consequently, it was hypothesized that predation and competition could be an adaptation process of NF to overcome environmental stress and exploit alternative or supplementary nutrient sources. Conclusions. The use of diverse native NF from cultivated and wild soils offer future prospects for the development of PPN management strategies in olive nurseries.

Description of the subject. Rodents may be major pests to crops and stored food, thus threatening food security. Among them, invasive species such as rats and mice are of particular concern since they are disseminated globally following international trade. We investigated the small mammal assemblage within the international seaport of Cotonou, Benin, in order to determine the relative importance and distribution of native vs invasive rodent species, as well as to evaluate the amount and associated costs of rodent-induced damages on imported/exported stored goods (here, rice). Objectives. Description of rodent assemblages within an African seaport, and evaluation of the associated damages on stored food stocks. Method. Rodent communities were described following trapping results while associated damages and costs were evaluated following a 25 days long monitoring campaign and subsequent economic estimation of loss. Results. Our results show that invasive mice and rats are, from far, the most impacting rodents in the storage warehouses, and that the associated economic losses are quite large. Moreover, we point towards a few environmental management procedures that may greatly reduce the impact of rodents on stored goods. Conclusions. Damages and costs due to invasive rodents within the Cotonou Harbor are so that they justify financial investment in rodent population control.

Description du sujet. Cet article présente les productions de biomasses aériennes et souterraines de jeunes taillis à très courte rotation, non fertilisés, plantés sur des sols marginaux. Objectifs. Deux sols contrastés ont permis de suivre la croissance de saule, peuplier et robinier pour estimer leur production de biomasse exportable, l’immobilisation de carbone et d’azote dans les racines, et quantifier les restitutions au sol par la sénescence foliaire. Une comparaison de deux densités de robinier (2 500 vs 5 000 pieds·ha-1) est également réalisée. Méthode. Les dispositifs sont instrumentés afin de quantifier le carbone (C) et l’azote (N) impliqués dans i) la sénescence foliaire retournant au sol, ii) les exportations et immobilisations de deux récoltes. Résultats. Le C total immobilisé en seconde récolte varie de 7,8 à 16,1 t·ha-1 et l’azote de 125 à 393 kg·ha-1. La sénescence foliaire restitue au sol 15 à 22 % du C total fixé, tandis que 17 à 31 % est immobilisé dans les racines. L’azote restitué au sol par la sénescence a varié de 48 à 79 kg·ha-1, soit respectivement 38 à 20 % du total, et celui retrouvé dans les racines a varié de 22 à 48 % du total. Nous n’avons pas constaté d’effet de la densité de plantation sur les différents compartiments des robiniers. Conclusions. Saule et robinier ont su mieux s’adapter que le peuplier aux conditions difficiles rencontrées. La fixation d’azote symbiotique du robinier pourrait être mieux exploitée pour accroitre la production de biomasse d’autres espèces, en cultures mixtes par exemple.

Description of the subject. Vegetation of high conservation value can establish in quarries, during or after exploitation. Alien plants could hamper this process and cause additional rehabilitation costs. However, the situation of plant invasion in quarries is largely unknown. Objectives. We aimed to assess alien plant invasion in active and abandoned quarries, and to identify the most invaded quarry sectors. Method. We surveyed 6,692 plots in 31 quarries in Belgium and recorded occurrence, density and cover of the 65 listed alien invasive plants in Belgium. Results. Fourteen species were recorded and 25 quarries contained at least one species. The two most occurring species, Buddleja davidii Franch. and Senecio inaequidens DC., were more widespread in quarries in activity. All sectors of the quarries were affected by alien plant invasion. Conclusions. Alien plant invasion in limestone quarries is highly variable, but significant. Considering the ecological potential of quarry sites, this issue should be better tackled.

Description du sujet. Dans les pays sahéliens, la répartition spatio-temporelle hautement variable des précipitations demeure une menace pour l’agriculture pluviale, malgré le grand nombre de techniques diffusées pour la conservation des eaux et des sols. Objectifs. Analyser plusieurs stratégies d’irrigation des cultures pluviales et évaluer l’impact probable des mesures économiques incitatives en vue de faciliter l’adoption de l’irrigation de complément à partir des petits bassins individuels de collecte des eaux de ruissellement face aux poches de sècheresse. Méthode. Les stratégies possibles d’irrigation de complément et les simulations des mesures économiques incitatives ont été analysées à partir d’un modèle bio-économique appliqué à une exploitation agricole type. Résultats. Les simulations montrent que l’irrigation de complément permet d’accroitre le revenu espéré des agriculteurs, comparativement à la situation sans irrigation. La culture du maïs, du sorgho et du mil sous l’irrigation de complément en année sèche augmente le revenu espéré de 26,49 % (133 030 francs CFA, équivalent à 202,80 euros) comparativement à la situation sans irrigation. Les simulations visant à promouvoir l’irrigation de complément à partir des petits bassins individuels sont axées sur quatre modalités de subventions et un système d’octroi de crédit aux ménages agricoles. Conclusions. Parmi les mesures incitatives, la subvention sous forme de travail contre nourriture pour mobiliser la main-d’œuvre en vue de construire les bassins semble particulièrement adaptée pour la mise à l’échelle de la pratique de l’irrigation de complément à partir des petits bassins individuels.

Description of the subject. Pleurotus species are cultivated on lignocellulosic substrates, in which contaminant fungi such as Trichoderma spp. are common. A selective substrate for Pleurotus provides the necessary conditions for protection against contaminants. Studies show that Paenibacillus polymyxa and other thermophilic bacteria benefit from the selectivity of Pleurotus cultivation substrate, however, little is known regarding these bacterial communities. Objectives. To evaluate the effect of substrate inoculation with Paenibacillus polymyxa on the productivity of Pleurotus pulmonarius and its protection against Trichoderma. Method. Barley straw inoculated with P. polymyxa and non-inoculated straw (control) was used following 0, 3 or 5 days of fermentation prior to heat treatment in order to produce the cultivation substrate. The microbiological content before and after the heat treatment, the mycelial colonization by P. pulmonarius and Trichoderma viride in competition and the yield of P. pulmonarius were all evaluated. Results. We observed that inoculation with P. polymyxa increased the number of cultivable bacteria and changed the composition of the community. The inoculation decreased the colonization ability of T. viride and favored the mycelial growth, although the yield of mushrooms was affected. Higher yields of P. pulmomarius were obtained in the control substrate where no contamination of Trichoderma spp. was observed. Conclusions. Addition of P. polymyxa modified the natural microbiological succession in a fermentation of barley straw for 5 days, favoring the competitiveness of P. pulmonarius against T. viride. Fermentation of barley straw for 3 days, followed by heat treatment, benefits the yield and protection of P. pulmonarius against Trichoderma viride.

With the bibliometric tools now at our disposal, it is easy to regularly monitor the evolution of our articles’ citation numbers. This therefore generated expectations, which were more than fulfilled when the official news came out last July: with an impact factor of 1.23 in 2018, our journal has crossed the symbolic threshold of 1. This impact factor remains modest for a generalist journal in the field of agronomy, but nevertheless it means we rank first among bilingual (French and English) scientific journals in this field. The evolution of BASE since 1997 reflects the constant concern for quality that drives the editorial and publishing boards. The Editorial Board has recently been renewed and will soon welcome members from other Belgian universities. The rigour in the selection of articles for publication translates to a decreasing total number of published articles: the rejection rate is in the high range of 70 to 90%. Moreover, the internal process for handling manuscripts is constantly evolving; for example, a new and strengthened procedure will improve the tracking of citations in journals known to be predatory. In addition, a new version of the manuscript management software, OJS, has just been put online. Finally, the switch from paper to fully digital is planned for 2020.

随着文献计量工具现在在我们的处置，很容易定期监测我们的文章引用数的演变。因此，这产生了人们的期望，当去年7月官方消息发布时，人们的期望得到了满足:2018年的影响因子为1.23，我们的期刊已经越过了1的象征性门槛。这个影响因子对于农学领域的通才期刊来说仍然是适度的，但这意味着我们在该领域的双语(法语和英语)科学期刊中排名第一。自1997年以来，BASE的发展反映了对质量的持续关注，这推动了编辑和出版委员会。编辑委员会最近得到了更新，不久将欢迎来自比利时其他大学的成员。在选择发表文章时的严格程度转化为发表文章总数的减少:退稿率在70%到90%的高范围内。此外，处理手稿的内部程序也在不断发展;例如，一个新的和加强的程序将改善对已知掠夺性期刊引用的跟踪。此外，新版本的稿件管理软件OJS刚刚上线。最后，从纸质到全数字化的转变计划在2020年完成。这些决定和发展并不能解决去年社论中指出的所有弱点(Pochet et al.， 2018)，但引用数量的显着增加表明BASE

Description of the subject. This research presents a novel approach for species discrimination of terrestrial processed animal proteins (PAP) using laser-induced breakdown spectroscopy (LIBS) as an alternative technique for determining feed safety. Objectives. To explore the correlation between LIBS results and elemental composition. To assess the potential of LIBS spectroscopic methods for species discrimination of terrestrial PAP. Method. A total of 42 reliable terrestrial PAP samples of ovine, bovine, porcine, and poultry origin were analyzed and LIBS spectra were innovatively collected from the separated bone fraction. Partial least squares-discriminant analysis (PLS-DA) models were performed on the dataset. Results. Significant differences were found in the element compositions (carbon, nitrogen, hydrogen, calcium, sodium, potassium, magnesium, zinc, strontium and barium, p < 0.05) of PAP from different sources, which indicated a high potential for species discrimination. High-marked LIBS spectral characteristics (21 variables) related to six elements (calcium, sodium, magnesium, zinc, strontium and barium) for different species of terrestrial PAP samples were found out. PAP from the four tested species could be well classified with high sensitivity and specificity (> 0.90), while the ruminant and non-ruminant PAP could be thoroughly discriminated. For the discriminant analysis of ruminant-derived components in terrestrial PAPs, the detection of 10%-40% adulteration can be achieved and the correct rate is about 95%. Conclusions. This study demonstrates that LIBS can mostly exhibit the elemental composition of different terrestrial PAP, and can be a promising method for discriminating the different animal species or animal groups (ruminant/non-ruminant) involved in terrestrial PAPs.

A total of 42 reliable terrestrial PAP samples of ovine, bovine, porcine, and poultry origin were analyzed and LIBS spectra were innovatively collected from the separated bone fraction. Partial least squares-discriminant analysis (PLS-DA) models were performed on the dataset. Results. Significant differences were found in the element compositions (carbon, nitrogen, hydrogen, calcium, sodium, potassium, magnesium, zinc, strontium and barium, p < 0.05) of PAP from different sources, which indicated a high potential for species discrimination. High-marked LIBS spectral characteristics (21 variables) related to six elements (calcium, sodium, magnesium, zinc, strontium and barium) for different species of terrestrial PAP samples were found out. PAP from the four tested species could be well classified with high sensitivity and specificity (> 0.90), while the ruminant and non-ruminant PAP could be thoroughly discriminated. For the discriminant analysis of ruminant-derived components in terrestrial PAPs, the detection of 10%-40% adulteration can be achieved and the correct rate is about 95%. Conclusions. This study demonstrates that LIBS can mostly exhibit the elemental composition of different terrestrial PAP, and can be a promising method for discriminating the different animal species or animal groups (ruminant/non-ruminant) involved in terrestrial PAPs.","PeriodicalId":87455,"journal":{"name":"Skull base surgery","volume":"65 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78555703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Description of the subject. Increasing plant diversity with flowering plants and releasing semiochemicals did not attract and support natural enemies of insect pests for biological control. Objectives. We tested the effect of intercropping oilseed rape with wheat, and releasing the sex pheromone of the ladybeetle Harmonia axyridis, on the abundance of aphids’ natural enemies. Method. Four treatments repeated three times were compared in an experimental field in Langfang (Hebei, China): (i) oilseed rape–wheat intercropping + sex pheromone release, (ii) oilseed rape–wheat intercropping solely, (iii) pure-stand wheat and (iv) pure-stand oilseed rape. Ladybeetles, hoverflies, lacewings and parasitoids were pan-trapped during nine weeks in spring 2016 in each treatment. Results. A diversity of natural enemy species was trapped. However, intercropping and the release of the sex pheromone did not significantly increase their abundance compared to pure-stands. Conclusions. The results are discussed in regard to technical issues to improve the experimental protocol for future research in China.
