Genetic diversity of african and worldwide strains of Ralstonia solanacearum as determined by PCR-Restriction Fragment Length Polymorphism analysis of the hrp gene region

The genetic diversity among a worldwide collection of 120 strains of #Ralstonia solanacearum# was assessed by restriction fragment length polymorphism (RFLP) analysis of amplified fragments from the hrp gene region. Five amplified fragments appeared to be specific to #R. solanacearum#. Fifteen different profiles were identified among the 120 bacterial strains, and a hierarchical cluster analysis distributed them into eight clusters. Each cluster included strains belonging to a single biovar, except for strains of biovars 3 and 4, which could not be separated. However, the biovar 1 strains showed rather extensive diversity since they were distributed into five clusters whereas the biovar 2 and the biovar 3 and 4 strains were gathered into one and two clusters, respectively. PCR-RFLP analysis of the #hrp# gene region confirmed the results of previous studies which split the species into an "Americanum" division including biovar 1 and 2 strains and an "Asiaticum" division including biovar 3 and 4 strains. However, the present study showed that most of the biovar 1 strains, originating from African countries (Reunion Island, Madagascar, Zimbabwe, and Angola) and being included in a separate cluster, belong to the "Asiaticum" rather than to the "Americanum" division. These African strains could thus have evolved separately from other biovar 1 strains originating from the Americas. (Résumé d'auteur

Demons of the Anthropocene. Facing Bruno Latour’s Gaia

As proposed in 2012 by the 3th International Geological Congress, the Anthropocene is the geological epoch of the Quaternary Period following the Holocene, the age that accounts for the transformation of humans into a force shaping the Earth, and of human actions into a geological phenomenon. Current debates on the Anthropocene are introducing new figures of impersonality, modes of political agency that are shaking the certainties of modern political philosophy. A key protagonist of this epistemic turn is Gaia, the Earth, the Greek Mother of most western gods.As proposed in 2012 by the 3th International Geological Congress, the Anthropocene is the geological epoch of the Quaternary Period following the Holocene, the age that accounts for the transformation of humans into a force shaping the Earth, and of human actions into a geological phenomenon.

A Futurist Art of the Past: Anton Giulio Bragaglia’s Photodynamism

The article examines "Un gesto del capo" (A gesture of the head), a 1911 “Photodynamic” picture by Anton Giulio Bragaglia (1890-1960), and discusses its Bergsonian motifs

Developing ecosystem accounts for the marine and coastal environment: Limitations, opportunities and lessons learned from the United Kingdom experience.

The marine and coastal environment provides crucial ecosystem services to sustain human activities and wellbeing. Advancing measurement frameworks to record the contribution of marine and coastal ecosystems to national wealth and economies and assess the sustainability of their use is therefore paramount. The recently proposed Ocean Accounting Framework outlined within the System of Environmental Economic Accounting represents a decisive step in this direction and provides a foundation for developing an integrated and standardised set of ecosystem accounts to support decision making and use of the seas. However, the ecological and socio-economic complexities of marine and coastal systems pose several challenges in compiling ecosystem accounts. This paper aims to discuss lessons learned, limitations and opportunities based on experience of developing an initial set of marine and coastal accounts for the United Kingdom. The paper reviews and addresses the challenges encountered and offers potential solutions for improving the measurement of marine and coastal ecosystems within accounting frameworks

The Kantian Sleep: On the Limits of the “Foucault Effect”

This paper analyzes the connection, established by Michel Foucault in The Order of Things, between the appearance of “man” as an anthropological presupposition of scientific and philosophical discourses, and the construction of a transcendental dispositif of thought. In accordance with this presupposition, the notion of life is conceived by Foucault as a by-product of Kantian modernity and inscribed within a Heideggerian ontotheology. By stressing the vitalist alternatives to this paradigm, the essay questions the hegemony of Western transcendentalism and proposes a naturalistic reorientation of Foucault’s intellectual project.Este artículo analiza la conexión establecida por Michael Focucault en The Order of Things (El Orden de las Cosas), entre la aparición del “hombre” como una presuposición antropológica de los discursos científico y antropológico, y la construcción de un dispositif trascendental del pensamiento. De acuerdo con esta presuposición, la noción de vida es concebida por Foucault como un subproducto de la modernidad Kantiana y está inscrita dentro de la ontoteología Heideggeriana. Al enfatizar las alternativas vitalistas de este paradigma, el ensayo cuestiona la hegemonía del trascendentalismo Occidental y propone una reorientación naturalista del proyecto intelectual de Foucault.Este artigo analisa a conexão estabelecida por Michael Foucault em The Order of Things (As palavras e as coisas), entre o surgimento do “homem” como uma pressuposição antropológica dos discursos científico e antropológico, e a construção de um dispositif transcendental do pensamento.
