The Temple and Its Surroundings on Fabrika Hill, Paphos: Preliminary Results of the French-Polish Excavations (2018–2019)

The field research conducted in Paphos in the framework of a joint project of the Université d’Avignon and the University of Warsaw focuses on the southern part of Fabrika hill with the aim to understand its role in the urban life of ancient Nea Paphos. Two seasons of the fieldwork (2018–2019) yielded evidence for the arrangement and chronology of a temple site of the Hellenistic and early Roman period. A preliminary exploration of underground chambers strongly suggests that they may have been a part of the same sacred area as the temple. Moreover, several burials as well as some walls and floors testify to the use of the site during the Byzantine and Medieval period

Forest vegetation management in Europe: current practice and future requirements

The book provides a record of the co-operation within Europe in the field of forest vegetation management through the Cost Action E47. The aims are: i)to provide a summary of the current state of the art' as it applies to forest vegetation management in Europe for scientists, practitioners and policymakers, affiliated to state, non-governmental or private commercial organizations; ii)to document existing forest weed control practices across Europe, and hence provide a resource of alternative solutions for individual countries sharing similar conditions and challenges; and iii)to identify common information gaps and future research needs, and hence potential future areas of collaboration for forest vegetation management scientists across Europe, along with barriers that may need to be overcome to achieve that aim.FORET;PEUPLEMENT FORESTIER;VEGETATION;CONCURRENCE VEGETALE;LUTTE;MODE DE TRAITEMENT;COOPERATION INTERNATIONALE;RECHERCHE DEVELOPPEMENT;DEVELOPPEMENT DURABLE;AMENAGEMENT FORESTIER;MAUVAISE HERBE;CONTROLE DE LA VEGETATION;PESTICIDE;LUTTE PHYTOSANITAIRE;IMPACT SUR L'ENVIRONNEMENT;DYNAMIQUE DE VEGETATION;HERBICIDE;BIODIVERSITE;ECOSYSTEME;HISTOIRE;GESTION FORESTIERE;EUROPE;VEGETATION FORESTIERE;ADVENTICE;ALTERNATIVES AUX HERBICIDES;

C’était l’affirmation-intuition que je formulai, voilà plus de quarante ans, en m’attachant à la rendre crédible. Plus tard, j’en élaborai la construction théorique, je présentai les illustrations qui légitiment le « détour » par l’anthropologie et en manifestent la nécessité. « L’avancée dans l’inconnu [auquel la modernité confronte] doit être éclairée, ce qui commence par u..

Young learners of modern foreign languages and their transition to the secondary phase: a lost opportunity?

Following publication of the National Languages Strategy on 18 December 2002 the teaching of foreign languages (FL) in the primary school is again high on the agenda in England as in other parts of Europe. Research has shown in the past (Burstall et al., 1974) that an early start in FL does not necessarily result in any long-term advantage in terms of proficiency. However, the above study also draws other conclusions, less widely reported, which remain significant. These include insufficient liaison between primary and secondary schools, lack of continuity in foreign language learning across phases, inadequate training of teachers, and a lack of differentiation by MFL secondary teachers. This article describes a small-scale research project which took place between April 2002 and May 2003. It sought to identify some of the main issues of transition from the perspective of the learners themselves, their foreign language teachers, heads of FL departments and head teachers at primary and secondary level. A complex and somewhat contradictory picture emerges from this study. On the one hand, there are many positive findings such as the enjoyment of languages and openness to other cultures and languages in the primary phase, greater oral fluency and confidence of learners when transferring to the secondary phase and enthusiasm shown for early language learning (ELL) by teachers in the primary and the secondary phase. On the other hand, opportunities which exist for building on primary language learning are largely wasted

Transpiration of four common understorey plant species according to drought intensity in temperate forests

International audienceAbstractKey messageWater use patterns of understorey vegetation are species-dependent.Calluna vulgarisshowed little or no regulation of transpiration in response to soil water depletion or air vapour pressure deficit, unlike Pteridium aquilinum, Rubus sp. and Molinia caerulea.ContextEvapotranspiration at forest stand scale is the sum of three components: overstorey and understorey transpiration, and evaporation from soil. During periods of soil water shortage, evapotranspiration of trees declines significantly, but the response of understorey vegetation is less well known. Some reports suggest that understorey vegetation can sometimes be the main source of water depletion in a forest stand during drought episodes.AimsWe assessed transpiration in response to decreased soil water content (SWC) and increased vapour pressure deficit (VPD) in the atmosphere for four understorey species with contrasting patterns of resource capture.MethodsPotted plants of Pteridium aquilinum, Molinia caerulea, Calluna vulgaris and Rubus sect. Fruticosi were grown under two radiation levels combined with three levels of SWC. Temperature, radiation, VPD and transpiration were monitored.ResultsCalluna vulgaris displayed a water spender behaviour with little or no regulation of transpiration during soil water depletion and increased VPD, whereas Pteridium aquilinum showed a low transpiration rate whatever the conditions. Rubus sect. Fruticosi gradually decreased transpiration during soil water depletion and increased VPD, whereas Molinia caerulea responded strongly to soil water depletion but only moderately to VPD.ConclusionThis study highlights the importance of adding identity and water use strategy of understorey species to the tree canopy component to establish a reliable forest water balance
