Soil microbial diversity effects on primary production and symbiotic interactions

2013

SPEEAEcolDurGenoSolGEAPSI; The importance of telluric microorganisms linked together by trophic exchanges with plants, that sustain all ecosystems through primary production, is known. However, the role of soil microbial diversity for primary production remains controversial. A diversity decreasing was achieved, by inoculating a sterilized soil with serial dilutions of a suspension from the same non-sterilized soil, to determine the consequences of microbial diversity erosion on the growth and fitness of three plant species more or less dependent on symbionts, Medicago truncatula, Brachypodium distachyon and Arabidopsis thaliana. The results showed that the impact of microbial diversity dec…

Kylät tulevaisuuden paikallisyhteisöinä

2018

Tämän artikkelin tavoitteena on kylien eli maaseutumaisten paikallisyhteisöjen tulevaisuuden luonteen hahmottaminen. Peilaan jälkimodernin paikallisyhteisön piirteitä aktiivisista kylistä keräämääni aineistoon. Miten jälkimodernille paikallisyhteisölle ominaiset piirteet, kuten kommunikatiivisuus ja avoimuus niissä rakentuvat? Mitä haasteita ne tuovat tulevaisuuden kylätoiminnalle ja kylien kehittämiselle? Jälkimodernit paikallisyhteisöt eivät rakennu vastavoimana individualismille, vaan osana sitä. Ne pyrkivät vastaamaan samalla sekä ihmisten yksilöllisiin intresseihin ja valintoihin että yhteisöllisyyden ja kuulumisen tarpeeseen. peerReviewed

Od folkloru do e-folkloru, czyli przemodelowanie przez Internet przedmiotu współczesnych badań folklorystycznych

2022

The emergence of the Internet, a new electronic means of communication, initiated the process of a qualitative change in contemporary culture. This has led, among other things, to a necessary redefinition ofthe subject of folklore research and, consequently, to highlighting its anthropological dimension. That, in turn, requires first and foremost a change in the concept of orality which in itself may no longer be reduced to direct (oral) provision of content, as the virtual language, enriched with a Computer interface, creates new possibilities for using words, along with their combination with image and music (visual folklore). On the one hand, on the Internet we may observe new aspects of…

Frontières des communautés polarisées : application à l'étude des théories complotistes autour des vaccins

2021

Les données des réseaux sociaux sont de plus en plus utilisées pour en extraire de la valeur, dans des domaines tels que le marketing, la politique ou la sociologie. Celles-ci peuvent être représentées sous forme de graphes, en modélisant précisément les interactions à travers des liens dirigés et pondérés. Dans l'analyse des données des réseaux sociaux, l'étude des communautés est une étape essentielle. Toutefois, pour une interprétation fine des phénomènes, il est également nécessaire d'étudier leurs interactions et de pouvoir détecter des traces de polarisation. Nous proposons une méthode qui permet d'évaluer l'antagonisme des communautés et d'identifier leurs frontières dans des réseaux…

Dynamic of the genetic structure of bacterial and fungal communities at different developmental stages of Medicago truncatula Gaertn. cv. Jemalong li…

2006

International audience; The genetic structure of bacterial and fungal communities was characterized in the rhizosphere of Medicago truncatula Gaertn. cv. Jemalong line J5 at five developmental stages (three vegetative and two reproductive stages), and in three compartments (bulk soil, rhizosphere soil and root tissues). The genetic structure of microbial communities was determined by cultivation-independent methods using directly extracted DNA that was characterized by automated ribosomal intergenic spacer analysis (ARISA). Principal component analyses (PCA) indicate that, for all developmental stages, the genetic structure of microbial communities differed significantly by compartment, wit…

Effects of Ocean Acidification on physiology, behaviour and ecology of fish

CO2 concentration in the atmosphere is increasing at unprecedented rate since the last 800,000 years due to rising fossil fuel combustion, industrial processes and land use by humans. By absorbing part of this gas from the atmosphere, Oceans contribute to the mitigation of climatic changes, but at the cost of greater modifications of their physical and chemical characteristics. CO2 dissolved in the seawater leads to increased bicarbonate (HCO3 -) and hydrogen ions (H+) concentrations with a consequent pH drop, a phenomenon known as Ocean Acidification (OA). If global policy will not put in force mitigation measures to reduce CO2 emissions, it is projected that partial pressure of dissolved …

Distribution and determinism of abundance, diversity and structure of microbial communities at different spatial scales to support agricultural devel…

2018

Les propriétés des sols déterminent notre capacité à produire des biens et des services en quantité et en qualité. Dans ce contexte, la composante microbienne des sols occupe une place prépondérante de part son abondance et son extrême diversité : on estime qu’un gramme de sol contient 109 bactéries et 105 champignons, pour environ 106 espèces bactériennes et 103 à 104 espèces de champignons. Cette diversité taxonomique des microorganismes du sol supporte une extraordinaire diversité fonctionnelle qui leur confère un rôle déterminant dans le fonctionnement du sol tant qualitativement (cycles biogéochimiques, structure du sol ; dégradation des composés exogènes, régulation biologique) que qu…

“The war is over”. Militarizing the language and framing the Nation in post-Brexit discourse

2020

This chapter analyzes the militarization of political language in digital contexts in the post-Brexit discourse, and how such militarization, which is often constitutive of hate speech, contributes to framing an “exclusive” concept of the nation whose meaning is reproduced and circulated (as well as challenged) in society. It will address the role of emotions and hate in language in fueling and aggregating online communities around a key political issue, i.e. the Brexit negotiations, and a core cultural and social concept, i.e. the nation. The militarization of language, which is based on certain discursive structures, e.g. war metaphors (Lakoff and Johnson 1980, Musolff 2020), is one of th…

Ethnobotanical knowledge in some rural communities of northern Sicily (Palermo, Italy)

2018

An ethnobotanical study was carried out to document the uses of wild plants among some local communities of Sicily (southern Italy). We recorded 48 taxa belonging to 45 genera included in 32 families. 30 taxa are used as medicinal plants, 22 taxa as food and 9 for handicraft use. In comparison with other ethnobotanical studies carried out in Sicily and other Italian territories, some uses of the plants reported by the local population in the study area are peculiarities. The analysis of data shows that the level of traditional knowledge on use of plants in province of Palermo is poor, highlighting a considerably advanced state of cultural erosion. The results of our investigation confirm th…
