Alors que les pelouses et prairies d'intérêt biologique comptent parmi les habitats protégés les plus menacés d'Europe tempérée, l'activité extractive offre des possibilités inattendues pour promouvoir ces écosystèmes. Au sein des carrières, des actions de restauration écologique tentent de reconstituer ces écosystèmes en danger. Notre étude s'est intéressée à la restauration passive de ces habitats par le biais de la recolonisation spontanée dans les carrières calcaires du sud de la Belgique. Cette étude vise également à soutenir le projet "Life in Quarries". Dix-sept remblais de terres de découvertures limoneuses spontanément recolonisés ont fait l'objet d'inventaires phytosociologiques et d'analyses de variables environnementales pour identifier (1) les facteurs expliquant la composition floristique des successions spontanées; (2) la diversité des communautés qui les composent et leurs principales caractéristique; et (3) le lien entre ces communautés spontanées et les écosystèmes de référence (prairies de fauche et pelouses calcaires). Une Analyse Canonique des Correspondances (CCA) menée sur les variables environnementales a permis d'identifier les facteurs contribuant le plus à la variation floristique et une analyse multivariée (nMDS à 2 dimensions) sur les abondances a permis d'identifier six communautés et de les relier aux écosystèmes de référence. Parmi les variables environnementales étudiées, l'effet site suivi de l'âge des successions, de la texture et de la pente du sol expliquent au mieux les variations de composition floristique. Une communauté s'apparente aux prairies de fauche et d'autres sont proches des prairies de fauche et des pelouses mésophiles. La recolonisation spontanée des remblais de terres limoneuses de découvertures en carrières calcaires révèle ainsi un réel potentiel pour la conservation d'habitats d'intérêt biologique. While conservation valuable grasslands and meadows are among the most endangered protected habitats in temperate Europe, extractive activity offers unexpected opportunities to promote these ecosystems. Within quarries, ecological restoration actions attempt to restore these endangered ecosystems. Our study focused on the passive restoration of these habitats through spontaneous recolonization in limestone quarries in southern Belgium. It also aims to support the "Life in Quarries" project. Seventeen spontaneously recolonized silty spoil heaps were subjected to phytosociological inventories and analysis of environmental variables. We investigated, through phytosociological relevés and environmental variables analysis, (1) the environmental factors driving floristic composition of spontaneous successions; (2) the diversity of the communities and their main characteristics; and (3) the similarity between these spontaneous communities and reference ecosystems such as hay meadows and calcareous grasslands. A canonical correspondence analysis (CCA) of environmental variables identified the most contributive factors to the floristic variation. A multivariate analysis (two dimensional nMDS ordination) of vegetation abundances helped identify six communities and linking them to the reference ecosystems. Within studied environmental factors, site effect followed by the age of the successions, soil texture and slope best explained variations in floristic composition. One community contained hay meadows while other communities shared common features with hay meadows and mesophilous grasslands. The spontaneous recolonizations of silty spoil heaps in limestone quarries thus reveal a true potential for the conservation of habitats of concern.

In his best-selling travel memoir, The Innocents Abroad, Mark Twain punningly refers to the black man who introduces him to Venetian Renaissance painting as a “contraband guide,” a term coined to describe fugitive slaves who assisted Union armies during the Civil War. By means of this and similar case studies, Paul H. D. Kaplan documents the ways in which American cultural encounters with Europe and its venerable artistic traditions influenced nineteenth-century concepts of race in the United States.Americans of the Civil War era were struck by the presence of people of color in European art and society, and American artists and authors, both black and white, adapted and transformed European visual material to respond to the particular struggles over the identity of African Americans. Taking up the work of both well- and lesser-known artists and writers—such as the travel writings of Mark Twain and William Dean Howells, the paintings of German American Emanuel Leutze, the epistolary exchange between John Ruskin and Charles Eliot Norton, newspaper essays written by Frederick Douglass and William J. Wilson, and the sculpture of freed slave Eugène Warburg—Kaplan lays bare how racial attitudes expressed in mid-nineteenth-century American art were deeply inflected by European traditions. By highlighting the contributions people of black African descent made to the fine arts in the United States during this period, along with the ways in which they were represented, Contraband Guides provides a fresh perspective on the theme of race in Civil War–era American art. It will appeal to art historians, to specialists in African American studies and American studies, and to general readers interested in American art and African American history.

Published by the CAPC musée d’art contemporain de Bordeaux in collaboration with BOM DIA BOA TARDE BOA NOITE, this reference book surveys the history of the independent publishing house Beau Geste Press (BGP) through the publications of its founding members Felipe Ehrenberg, Martha Hellion, David Mayor and Chris Welch, and of the numerous visitors to its rural outpost – visual poets, neo-Dadaists and artists affiliated with the Fluxus movement – from 1971 to 1976. A ‘catalogue dé-raisonné’ of all the printed matter produced by BGP, it is complemented by critical essays and first-hand texts that explore the working methods (economy and autonomy of production, distribution of books via post) and document the international influence of this short-lived ‘community of duplicators, printers, and artisans’.
