SAFER : le temps de la rétrocession respectueux de la Constitution

2018

International audience; L’absence de sanction de l’obligation pour la SAFER de rétrocéder un bien préempté dans le délai de 5 ans ne porte pas une atteinte disproportionnée au droit de propriété, à la liberté contractuelle et à la liberté d'entreprendre protégés par les articles 2 et 4 de la Déclaration des droits de l’homme et du citoyen. Cons.

The proposal to transform an old limestone quarry into a botanical garden with a rainforest zone: a case study

2019

Nowadays, a significant part of cities is tackling the problems with post-mining areas. This manuscript is an original research which shows possibilities of their reclamation. The aim of the article is to present the proposal of developing the closed limestone quarry and creating a botanical garden. The proposed spatial solutions allow for creating a new, tourist and recreation space, maintaining the natural heritage. The work also assumed carrying out a dendrological inventory, in order to determine the existing dendrofl ora. The required spatial, nature and communication analyses, which illustrate the current condition of the area and defi ne further design works, have also been carried o…

Subtropical streams harbour higher genus richness and lower abundance of insects compared to boreal streams, but scale matters

2018

Aim: Biological diversity typically varies between climatically different regions, and regions closer to the equator often support higher numbers of taxa than those closer to the poles. However, these trends have been assessed for a few organism groups, and the existing studies have rarely been based on extensive identical surveys in different climatic regions. Location: We conducted standardized surveys of wadeable streams in a boreal (western Finland) and a subtropical (south-eastern Brazil) region, sampling insects identically from 100 streams in each region and measuring the same environmental variables in both regions. Taxon: Aquatic insects. Methods: Comparisons were made at the scale…

Thèse : L'intégration de l'environnement au droit de l'électricité. Vers le renouvellement d'un service public.

2012

Equality, continuity and adaptability. Foundations of the right of the public utilities, Rolland laws apply vigorously to the public service for electricity, where activities did not change since the advent of the « electricity fairy ». It is always about producing, transporting, distributing and supplying electricity, respecting the general interest. Nevertheless, the legal framework applicable to these activities is under a dramatic transition, stemming from the will of the European Union to create a single market for electricity. These changes incrementally drive to a shift of the public utility, basically socially oriented, to more and more demanding and diversified economic objectives.…

Tree species influences diversity of ground-dwelling insects in afforested fields

2015

Abstract Impaired natural ecosystems, such as agricultural lands, are restored toward original or other target stage. Because the long agricultural history has changed the physical, chemical and biological features of the soil, afforested fields can harbor novel species assemblages and interactions. Our overall aim was to quantify the diversity of ground beetles and ants in early successional afforested fields. In a large scale field experiment, we compared plots that had been afforested 25 years ago by planting monocultures of birch, pine or spruce trees. A total of 4080 carabid individuals representing 41 species, and 131,933 ant individuals representing 15 species were recorded. Both the…

Towards a framework for assessment and management of cumulative human impacts on marine food webs

2015

Effective ecosystem-based management requires understanding ecosystem responses to multiple human threats, rather than focusing on single threats. To understand ecosystem responses to anthropogenic threats holistically, it is necessary to know how threats affect different components within ecosystems and ultimately alter ecosystem functioning. We used a case study of a Mediterranean seagrass (Posidonia oceanica) food web and expert knowledge elicitation in an application of the initial steps of a framework for assessment of cumulative human impacts on food webs. We produced a conceptual seagrass food web model, determined the main trophic relationships, identified the main threats to the fo…
