Octubre del 2000, constitución de AEIE. Objetivos: conocimiento y compilación pequeña Jurisprudencia Tribunales de ambos lados, análisis y difusión de datos y formación en Derecho transfronterizo..1990, hainbat ekimen alde bietako juristak elkarrengana hurbiltzeko. 1994, Abokatuen Elkargo bietako Hitzarmena. 1997, proiektua agortzen ari zeneko seinaleak. 1998, Baiona eta Donostiako Zuzenbide Fakultateak mugaz gaindiko proiektu juridikoetan interesaturik. 1998tik 2000ra, Behakundearen prestalanak. 1999, Euskadi-Akitaniaren dirulaguntza proiektuarentzat. 2000ko urria, AEIE delakoa eraturik. Helburuak: alde bietako Auzitegietako Jurisprudentzia txikia ezagutzea eta biltzea, datuen azterketa eta zabalkundea eta Mugaz gaindiko Zuzenbidean prestakuntza ematea.1990, diverses initiatives pour rapprocher les juristes des deux côtés. 1994, Convention des deux Barreaux. 1997, signes d'épuisement du projet. 1998, intérêt des Facultés de Droit de Bayonne et Saint-Sébastien pour des projets juridiques transfrontaliers. 1998 à 2000, travaux préparatoires de l'Observatoire. 1999, subvention au projet pour Euskadi-Aquitaine. Octobre 2000, constitution de AEIE. Objectifs: connaissance et petite compilation Jurisprudence Tribunaux des deux côtés, analyse et diffusion de données et formation en Droit transfrontalier..In 1990, there were various initiatives to bring together the jurists of both sides. In 1994, a Convention of the two Bar Associations was held. In 1997, there were signs that the project had exhausted its possibilities. In 1998, there was some interest in the Law Faculties of Bayonne and San Sebastian on transborder legal projects. From 1998 to 2000, the observatory preparatory projects were carried out. In 1999, the project was subsidised by Euskadi-Aquitaine. In October 2000, the AEIE was constituted. Its objective is the knowledge and compilation of jurisprudence from the Courts of both sides, its analysis and transborder law data and training dissemination

Non-stomatal processes reduce gross primary productivity in temperate forest ecosystems during severe edaphic drought

Severe drought events are known to cause important reductions of gross primary productivity (GPP) in forest ecosystems. However, it is still unclear whether this reduction originates from stomatal closure (Stomatal Origin Limitation) and/or non-stomatal limitations (Non-SOL). In this study, we investigated the impact of edaphic drought in 2018 on GPP and its origin (SOL, NSOL) using a data set of 10 European forest ecosystem flux towers. In all stations where GPP reductions were observed during the drought, these were largely explained by declines in the maximum apparent canopy scale carboxylation rate VCMAX,APP (NSOL) when the soil relative extractable water content dropped below around 0.4. Concurrently, we found that the stomatal slope parameter (G1, related to SOL) of the Medlyn et al. unified optimization model linking vegetation conductance and GPP remained relatively constant. This result was unexpected as it implies that NSOL (instead of stomatal closure) was the main process limiting GPP during drough

Concurrently, we found that the stomatal slope parameter (G1, related to SOL) of the Medlyn et al. unified optimization model linking vegetation conductance and GPP remained relatively constant. These results strengthen the increasing evidence that NSOL should be included in stomatal conductance/photosynthesis models to faithfully simulate both GPP and water fluxes in forest ecosystems during severe drought
