Biogeography of soil microbial communities: a review and a description of the ongoing french national initiative
2010
International audience; Microbial biogeography is the study of the distribution of microbial diversity on large scales of space and time. This science aims at understanding biodiversity regulation and its link with ecosystem biological functioning, goods and services such as maintenance of productivity, of soil and atmospheric quality, and of soil health. Although the initial concept dates from the early 20th century (Beijerinck (1913) De infusies en de ontdekking der backterien, in: Jaarboek van de Knoniklijke Akademie van Wetenschappen, Muller, Amsterdam), only recently have an increasing number of studies have investigated the biogeographical patterns of soil microbial diversity. A such …

Harnessing the biodiversity value of Central and Eastern European farmland
2015
A large proportion of European biodiversity today depends on habitat provided by low‐intensity farming practices, yet this resource is declining as European agriculture intensifies. Within the European Union, particularly the central and eastern new member states have retained relatively large areas of species‐rich farmland, but despite increased investment in nature conservation here in recent years, farmland biodiversity trends appear to be worsening. Although the high biodiversity value of Central and Eastern European farmland has long been reported, the amount of research in the international literature focused on farmland biodiversity in this region remains comparatively ti…
Terres et pierres pour matières de cultures : l'apparition et la diffusion de nouveaux modes et matériaux de construction dans le Nord-Est de la Gaul…
2017
Roman building materials often arose a growing interest through their presence in early contexts, sometimes way before Gallic Wars. Made from natural resources, their final shape corresponds to anthropogenic and cultural constraints. However, even if building materials are not neglected during archaeological excavations, so far they have been considered as playing a minor part in understanding ancient sites. Economical, technical and architectural aspects are regularly mentioned, creating the picture of an exploited « landscape » around the studied areas, but the question of materials as cultural markers witnessing intercultural relations between Rome and Gallic tribes has never really been…
Appearance and use of Roman roofing materials in the region of the Aedui and Lingones
2014
Römische Konstruktionstechniken und Baustoffe können als Anzeichen für Romanisierung gewertet werden. Sie legenZeugnis von den veränderten Verhaltensweisen ab, wie die Haeduer und die Lingonen mit den natürlichen Ressourcenumgingen, um diese Materialien zu produzieren. Es können deutliche Unterschiede zwischen diesen beiden gallischenStämmen hinsichtlich des Einsatzes von Ziegel- und Steindächern beobachtet werden. Die Haeduer verwenden meistensZiegel für ihre Dächer, selbst wenn die lokal verfügbaren natürlichen Ressourcen eine Produktion dieses Baustoffesnicht erlauben. Im Gegensatz dazu kommen bei den Lingonen Ziegel nur dann zum Einsatz, wenn die entsprechendenRessourcen vorhanden …
Fleurey-sur-Ouche (Côte-d’Or). Maison de santé [notice archéologique]
2019
Une troisième fouille, dans un même secteur au centre du village de Fleurey-sur-Ouche, a pu compléter les informations déjà récoltées suite aux différentes opérations menées depuis 2015. La fouille, sur une surface de 2 745 m2, a mis au jour une occupation dense, constituée principalement de structures en creux pour la première phase du Moyen Âge central ; la seconde phase est, elle, matérialisée par des bâtiments dotés de caves, remblayées, selon les premières observations, au XIIIe s.
Fleurey-sur-Ouche (Côte-d’Or). Lotissement la Velle, rue de la gare [notice archéologique]
2019
Le village de Fleurey-sur-Ouche, situé à une quinzaine de kilomètres au N-O de Dijon, a connu plusieurs interventions archéologiques depuis 2015 dans un même secteur au cœur du bourg. Un diagnostic conduit en 2016 avait mis au jour plusieurs occupations successives s’échelonnant du Xe au XVIe s. sur la parcelle concernée par la construction d’un futur lotissement. La fouille menée sur une surface de 3 320 m2 a permis de confirmer cette occupation diachronique [...]
Ressources naturelles et développement dans le monde tropical : les contradictions entre dynamiques écologiques, reproduction sociale et ordre économ…
2013
Natural resources are in the midst of contradictory dynamics. While they are essential to the reproduction of societies and life, actual organization of the world economy subordinates them to logics of accumulation. In addition to the fact that these logics don't take into account (consider) the physical limits inside of which humanity evolves, they induce problematic socio-ecological inequalities at different scales. Indeed, actual international economic order tends to generate ecologically unequal exchanges, which disrupt the development of primary exporting countries and threaten the most vulnerable populations and ecosystems inside of them.Tropics are the typical context in which such c…
How Good Is This Page? Benefits and Limits of Prompting on Adolescents’ Evaluation of Web Information Quality
2019
International audience; The present study examined adolescents' detection of features that affect the quality of Web information. In Experiment 1, participants (12-16 years old) rated the goodness/usefulness of four Web-like documents for a simulated study assignment. Each document came with an issue that potentially undermined its quality. Two documents had source-related issues (i.e., non-competent author, outdated) and two had content-related issues (i.e., topic mismatch, poor readability). Most students failed to notice the issues, including topic mismatch. The participants also produced inconsistent evaluations of topic-match, readability, author competence and currency. In Experiment …
University Governance and Finance: The Impact of Changes in Resource Allocation on Decision Making Structures
2002
When trying to account for changes that take place over time in the structure of any organisation, social scientists often use a conceptual framework known as resource dependency theory. This theory assumes that organisations survive only if they are able to react to changes that occur in the world around them in order to obtain the resources they need to stay in operation. Since they have the capacity for independent action, organisations are not passively shaped by their environment; they sometimes are also able to influence it.
