Global data on earthworm abundance, biomass, diversity and corresponding environmental properties

Publisher Copyright: © 2021, The Author(s).Earthworms are an important soil taxon as ecosystem engineers, providing a variety of crucial ecosystem functions and services. Little is known about their diversity and distribution at large spatial scales, despite the availability of considerable amounts of local-scale data. Earthworm diversity data, obtained from the primary literature or provided directly by authors, were collated with information on site locations, including coordinates, habitat cover, and soil properties.

La pierre ollaire en Roussillon : état des découvertes

La pierre ollaire a été utilisée dans le massif alpin pour la fabrication de nombreux objets, notamment, à partir de l’époque romaine, des pots tournés. Au cours du Bas Empire et du haut Moyen Âge, ces pièces sont diffusées dans les régions limitrophes. En Languedoc, quelques fragments de vases en pierre ollaire ont été récemment signalés ou publiés, mais jusqu’à présent ces découvertes étaient limitées à l’Hérault. Notre étude porte sur 20 fragments provenant du site de Ruscino, auxquels viennent s’ajouter quelques fragments découverts lors de fouilles ou prospections en Roussillon (Brouilla, Palau-del-Vidre, Ultréra). Il s’agit de pièces qui appartiennent au répertoire alpin : formes hautes, à bord droit et à panse sub-verticale, parfois munies d’un cordon, ou d’un décor de cannelures. Certaines portent des traces de leur mise en œuvre : sillons de tournage, traces de pic ou de ciseau. Les roches utilisées sont de nature et de provenance diverses (principalement des chloritoschistes). Cette série, relativement importante au vu des découvertes languedociennes, et de l’éloignement de la région de production, permet d’étendre largement vers le sud l’aire de diffusion de ces objets durant la période wisigothiqueLa pedra serpentina va ser utilitzada en el massís alpí per a la fabricació de nombrosos objectes, en particular dels vasos tornejats a partir de l’època romana. Durant el Baix Imperi i l’Alta Edat Mitjana, aquestes peces van ser difoses en les regions limítrofes. En el Llenguadoc, alguns fragments de vasos en serpentina van ser senyalats ο publicats recentment, però fins ara aquestes descobertes eren limitades a l’Herault. El nostre estudi concerneix 20 fragments que vénen del site de Ruscino, als quais s’afegeixen alguns fragments descoberts al moment d’investigacions ο de prospeccions en Rosselló (Brulla, Palau del Vidre, Ultrera). Es tracta de peces que pertanyen al repertori alpí: formes altes, a límit dret i amb buc subvertical, a vegades dotades d’un cordó, ο d’una decoració de canaleta. Algunes tenen senyals de llur realització: regues tornejades, senyals de pic ο d’estisores. Les roques utilitzades son de natura i de provinença diverses (principalment “chloritoschistes”). Aquesta sèrie, relativament important vist les descobertes llenguedocianes, i de l’allunyament de la regió de producció, permet d’estendre amplament cap al sud l’àrea de difusió d’aquests objectes durant el període visigòticThe soapstone pots in Roussillon: statement of discoveries.The soapstone was used in the alpine mountains to make a lot of objects, among which, since the roman period, some throwed pots. During the late empire and the early middle age, these pieces were diffused into bordering regions. In the Languedoc region, some soapstone pots fragments were recently published but until now, these discoveries havent’t go past the Herault River. Our study concerns twenty fragments coming from the Ruscino site, and other fragments which were discovered during excavations or prospecting in the Roussillon country. These pieces belong to the alpine repertoire: cylindrical high forms, sometimes with a fluted decoration. Most of them carry throwing grooves or tools marks. This range of fragments, relatively important compared to the Languedoc series, and to the remoteness of the source of production, allows spreading southward the distribution area of these pieces during the wisigothic perio

Dampening type 2 properties of group 2 innate lymphoid cells by a gammaherpesvirus infection reprograms alveolar macrophages.

peer reviewedImmunological dysregulation in asthma is associated with changes in exposure to microorganisms early in life. Gammaherpesviruses (γHVs), such as Epstein-Barr virus, are widespread human viruses that establish lifelong infection and profoundly shape host immunity. Using murid herpesvirus 4 (MuHV-4), a mouse γHV, we show that after infection, lung-resident and recruited group 2 innate lymphoid cells (ILC2s) exhibit a reduced ability to expand and produce type 2 cytokines in response to house dust mites, thereby contributing to protection against asthma. In contrast, MuHV-4 infection triggers GM-CSF production by those lung ILC2s, which orders the differentiation of monocytes (Mos) into alveolar macrophages (AMs) without promoting their type 2 functions. In the context of γHV infection, ILC2s are therefore essential cells within the pulmonary niche that imprint the tissue-specific identity of Mo-derived AMs and shape their function well beyond the initial acute infection

Roches ornées, roches dressées

Jean Abélanet peut être considéré comme le pionnier de l'archéologie actuelle sur les terres nord-catalanes. Ce rôle de précurseur dans la découverte de sites majeurs, mais aussi sa contribution savante à l'avancée des études préhistoriques, tant sur le mégalithisme en Pyrénées que sur l'art rupestre post-glaciaire en Europe occidentale, justifient l'hommage qui lui est rendu par la communauté des chercheurs. Cet hommage a pris la forme d'un colloque placé sous l'égide de l'Association Archéologique des Pyrénées-Orientales, dont il fut membre fondateur, et de l'Université de Perpignan, dont il fut le premier enseignant en Préhistoire. Sont rassemblées dans cet ouvrage les contributions de 74 auteurs et co-auteurs. Ces 576 pages, abondamment illustrées par près de 300 figures, abordent des sujets très divers qui reflètent les différents champs d'études balayés par son insatiable et humaniste curiosité. Une première partie, remontant aux sources des arts et des mythes, éclaire certains aspects de l'art rupestre et du mégalithisme, depuis leurs origines jusqu'à nos jours, à partir de recherches récentes menées dans l'Ancien monde, des terres australes d'Afrique jusqu'en Europe de l'Ouest. Le second thème, tout en laissant une large place à l'étude des arts et des traditions funéraires, rassemble des travaux pluridisciplinaires menés à l'orient des Pyrénées, travaux d'historiographie, de palynologie, de géologie, d'archéologie préhistorique et historique, d'histoire ou d'ethnologie
