Abstract

Le Bas Maine (département de la Mayenne, ouest de la Sarthe et sud-ouest de l'Orne) reprend les contours de la cité antique des Diablintes. Les recherches anciennes et quelques découvertes ponctuelles indiquaient ici la présence probable de zones de production sidérurgique antérieures au XVe s. et à l'apparition du haut-fourneau dans cette région. La présente étude le confirme. L'utilisation de différentes méthodes de recherche documentaire et les vérifications au sol ont permis d'enregistrer plus de 420 sites liés à la réduction directe qui forment des zones de production, dont les plus importantes se trouvent à la limite des départements de la Sarthe et de la Mayenne. L'approche régionale a été complétée par la fouille d'un atelier de réduction directe du minerai de fer d'époque romaine. Les structures mises au jour à cette occasion ainsi que les analyses archéométriques menées sur les vestiges collectés ont permis d'apporter des éléments nouveaux sur l'organisation de la production du fer durant l'époque romaine, la plus représentée dans la région, et de proposer l'existence de variations techniques au sein de la filière de réduction directe du fer. La mise en perspective de ces résultats permet de dresser un tableau de nos connaissances sur la sidérurgie ancienne du fer dans le Bas Maine et de proposer un éclairage nouveau sur les facteurs techniques sociaux et économiques liés à cette production.

Abstract

La présente étude s’attache à décrypter l’organisation et le fonctionnement de juridictions situées au premier niveau de l’appareil judiciaire. Longtemps dépeintes comme inefficaces, incompétentes, partiales et même âpres au gain, les justices seigneuriales font l’objet, depuis plusieurs années déjà, d’une révision historiographique qui montre au contraire qu’elles peuvent être pleinement parties prenantes des régulations sociales, attachées davantage à réconcilier qu’à sanctionner les plaideurs. Fondée sur le dépouillement exhaustif d’archives de la pratique judiciaire, l’étude tente une approche à la fois quantitative et qualitative des registres audienciers d’affaires judiciaires et d’amendes, tout en faisant une large place au droit coutumier en vigueur dans ces deux provinces du royaume de France. Cette recherche examine ainsi la manière dont l’audience s’organise, le personnel qu’elle mobilise, mais également l’activité quotidienne des tribunaux seigneuriaux à travers la procédure suivie, le type d’affaires jugées et les condamnations prononcées ; le tout en essayant de dégager les « modèles » susceptibles d’avoir influencé la conduite de l’exercice judiciaire dans cette région et à ce niveau institutionnel. Au-delà de ces aspects strictement juridique et judiciaire, ce travail tente enfin d’appréhender le profil des plaideurs, la manière dont ils usent de la justice, et plus largement la place et le rôle assignés à cette dernière vis-à-vis des justiciables et de l’autorité seigneuriale.

Abstract

This Special Issue gathers papers reporting research on various aspects of remote sensing of Sea Surface Salinity (SSS) and the use of satellite SSS in oceanography. It includes contributions presenting improvements in empirical or theoretical radiative transfer models; mitigation techniques of external interference such as RFI and land contamination; comparisons and validation of remote sensing products with in situ observations; retrieval techniques for improved coastal SSS monitoring, high latitude SSS and the assessment of ocean interactions with the cryosphere; and data fusion techniques combining SSS with sea surface temperature (SST). New instrument technology for the future of SSS remote sensing is also presented.

Abstract

Spruce budworm (Choristoneura fumiferana (Clem.)) outbreaks are a dominant natural disturbance in the forests of Canada and northeastern USA. Widespread, severe defoliation by this native insect results in large-scale mortality and growth reductions of spruce (Picea sp.) and balsam fir (Abies balsamea (L.) Mill.) forests, and largely determines future age–class structure and productivity. The last major spruce budworm outbreak defoliated over 58 million hectares in the 1970s–1980s, and caused 32–43 million m3/year of timber volume losses from 1978 to 1987, in Canada. Management to deal with spruce budworm outbreaks has emphasized forest protection, spraying registered insecticides to prevent defoliation and keep trees alive. Other tactics can include salvage harvesting, altering harvest schedules to remove the most susceptible stands, or reducing future susceptibility by planting or thinning. Chemical insecticides are no longer used, and protection strategies use biological insecticides Bacillus thuringiensis (B.t.) or tebufenozide, a specific insect growth regulator. Over the last five years, a $30 million research project has tested another possible management tactic, termed an ‘early intervention strategy’, aimed at area-wide management of spruce budworm populations. This includes intensive monitoring to detect ‘hot spots’ of rising budworm populations before defoliation occurs, targeted insecticide treatment to prevent spread, and detailed research into target and non-target insect effects. The objective of this Special Issue is to compile the most recent research on protection strategies against spruce budworm. A series of papers will describe results and prospects for the use of an early intervention strategy in spruce budworm and other insect management.
