Near real time surface ocean velocity in the Bay of Biscay - Basque Country from Mai to September 2016

The data set consists of maps of total velocity of the surface current in the Southeastern Bay of Biscay averaged over a time interval of 1 hour around the cardinal hour. Surface ocean velocities estimated by this HF Radar(4.65 MHz) are representative of the upper 2-3 meters of the ocean. The main objective of near real time processing is to produce the best product from available data at the time of processing. Total velocities are derived using least square fit that maps radial velocities measured from individual sites onto a cartesian grid. The final product is a map of the horizontal components of the ocean currents on a regular grid in the area of overlap of two or more radar stations.

Quelques traits du développement du basque L2 en contexte de revitalisation de la langue à travers l’immersion scolaire

Cette recherche vise à identifier quelques traits du développement du basque L2 dans un contexte de revitalisation de la langue à travers l’immersion scolaire. L’analyse de la restitution orale des contes en basque par un même groupe d’élèves de cinq à huit ans dont la langue première est l’espagnol, constitue l’élément empirique de la présente recherche. Ces élèves habitent dans un entourage hispanophone mais sont scolarisés en basque par immersion. Les données sont comparées avec celles des élèves de basque L1 provenant d’un entourage bascophone. L’analyse de diverses dimensions des contes suggère que la scolarisation en basque L2 à travers l’immersion favorise le développement du basque dans un contexte de revitalisation. En même temps, l’analyse permet d’identifier quelques traits spécifiques du basque L2 et qui sont distincts du basque L1. (DIPF/Orig.)

Project work in a Basque L2 classroom: students’ perceptions

[EN] Project Work has been acknowledged as an efficient medium for language learning for more than two decades (Stoller, 2006) according to the numerous successful applications of project-based programmes that have been reported. In spite of the lack of sufficient controlled studies to assess the benefits of project work, and the existence of some studies giving evidence of students discontent with project work, the reports given by second language (SL) and foreign language students (FL) who have experienced project based instruction give support to the success attributed to project-based learning, as they recognised having improved language skills, learnt content, developed real life skills, as well as gained in self-confidence and motivation (Sierra, 2008 and 2011; Stoller, 2006). The aim of the present study is to explore some key issues involved in implementing a project-based programme focusing on the students’ perceptions of learning gains, their views on the collaborative assessment scheme used in the programme, and the students’ overall evaluations of the implementation of project work in a post-compulsory secondary education context in Navarre, Spain, with students learning Basque as a second language. A group of 12 students enrolled in a project work based programme participated in the study. Results showed that the students’ perceptions were very positive concerning doing projects, learning gains and group work, although more grammar instruction and teacher-fronted activities were requested by the students. However, the collaborative assessment process and the use of a Notebook/Diary as a reflection tool bore mixed evaluations.

Does spatial distribution of fauna depend on algal belts on intertidal boulder fields of the French Basque coast ?

To determine good ecological status and conservation of the Sub-Marine area of the Bay of Biscay, the implementation of a new rocky intertidal habitats monitoring is needed. A protocol has been adapted from the Brittany protocol for the water body FRFC11 "Basque coast" for the two indicators "intertidal macroalgae" and "subtidal macroalgae" under the Water Framework Directive to qualify the ecological. However no protocol has been validated for fauna in front of meridional characters of the benthic communities. Investigations carried out on macroalgae communities on intertidal area in WFD framework, since 2008, constitute an important working basis. This is the aim of the Bigorno project (Intertidal Biodiversity of the south of the Bay of Biscay and Observation for New search and Monitoring for decision support), financed by the Agency of Marine Protected Areas and the Departmental Council. To implement knowledge, a sampling protocol has been used in 2015 on the boulder fields of Guéthary. This site is part of Natura 2000 area "rocky Basque coast and offshore extension "It constitutes also a Znieff site and restricted fishing area. The sampling strategy considers the heterogeneity of substrates and the presence of intertidal microhabitats. Two main habitats are present: "mediolittoral rock in exposed area habitat" and "boulder fields". Habitat "intertidal pools and permanent ponds" is also present but, it is not investigated. Sampling effort is of 353 quadrats of 0.1 m², drawn randomly according to a spatially stratified sampling plan, defined by habitat and algal belts. Taxa identification and enumeration are done on each quadrat. The objective of this work is to expose results from data collected during 2015 sampling program. The importance of characterizing benthic fauna communities spatial distribution belonging to the Basque coast according to algal belts defines during the WDF survey was highlighted. Concurrently, indicators of biodiversity were studied.

Indicator species of intertidal boulder fields on the French Basque coast

The rocky Basque coast presents an interest both in terms of biogeography and its patrimonial situation, alongside its habitats, fauna and flora. The aim of the BIGORNO project (Intertidal Biodiversity of the south of the Bay of Biscay and Observation for New research and Monitoring for decision support), financed by the Agency of Marine Protected Areas (AAMP) and the Departmental Council (CD 64), is to respond to significant deficiencies on biocenosis in the southern marine subregion “Bay of Biscay”. Investigations carried out in the WFD, since 2008, constitute an important basis of work for integration of fauna. Field studies undertaken since 2015 consisting of a sampling design suited to the substrates heterogeneity and the presence of microhabitats were established on an intertidal area specifically on a "Boulder fields" habitat. Assessment was undertaken by sampling quadrats of 0.1 m² drawn randomly from a spatially stratified sampling plan. Our study aims for a better understanding of stratification of this habitat and allowed us to highligh tindicator taxa of the "Boulder fields" habitat. Functions included in the package indicspecies (CRAN) were used to conduct indicator species analysis and to assess the significance of the relationship between taxa or taxa combinations and the habitat. It is therefore possible to describe some species or species groups which are specific to boulder fields through the assessment of their functional traits and local biodiversity. These various analyses allow for a sustainable way of monitoring the Basque intertidal rocky shore.

Assessment of positive parenting programmes in the Autonomous Region of the Basque Country (Spain)

This paper presents the results of a study aimed at identifying and assessing positive parenting programmes and activities carried out in the Autonomous Region of the Basque Country (ARBC), Spain. The study is a development of the III Inter-institutional Family Support Plan (2011), drafted by the Basque Government's Department of Family Policy and Community Development, and its aim is to offer a series of sound criteria for improving existing programmes and ensuring the correct design and implementation of new ones in the future. It analyses 129 programmes and gathers data relative to institutional management and coordination, format, quality of the established aims, adaptation to the theoretical proposal for an Optimal Positive Parenting Curriculum, scientific base, use of the framework of reference for competences, working method, assessment techniques, budgets and publicity, among others. The results highlight the good quality of the programmes' aims and content, and the poor systematic assessment of these same aspects. The study concludes with a series of recommendations for improving the initiatives, integrated into a proposal for a system of indicators to assess and implement positive parenting programmes.

Citizenship, immigration and the Basque State

Immigration is directly related to citizenship, the nation and the state, revealing as it does the constructed nature of those categories. Here the impact of immigration on Euskal Herria is examined from this perspective, looking first at the processes of migration to it which have produced the make-up of present-day Basque society to a large extent. This is followed by a consideration of the way migratory movements have been viewed by the movement for the development of Euskal Herria into a state, the Basque nationalist movement, since these attitudes have played a fundamental role in defining Basque citizenship. After some observations about multiculturalism, the chapter concludes with a look at how the creation of a Basque state might contribute to this and the issues that will be raised.

Intérêt biogéographique de la côte basque rocheuse

During recent decades, works on rocky shore biodiversity have been multiplied in the southern part of the Bay of Biscay and more precisely on intertidal and subtidal area were communities present a great interest. Necessity of conservation of coastal habitats and their communities and a growing pressure on coastal environments explain awareness of services provided by these ecosystems. Those communities are very sensitive to water quality change. Moreover, since the beginning of the XXI century various European directives require a good ecological status of coastal waters and conservation of their communities : Water Framework Directive (WFD), Marine Strategy Framework Directive (MSFD) and conservation of habitats with Directive Habitat Fauna and Flora (DHFF).... Integrated environmental status assessment approach is needed for this requirement in front of specific component at the regional scale of the Bay of Biscay. This analyze, at this regional scale, bring a particular interest to follow some biological groups in front of their ecological sensitivity. Among them, some example are listed like algae, invertebrate as species of mollusc opistobranch and fishes of the family blennidae are targets of interest for future monitoring. The biogeographic specificity of species of these groups is to present strong ecological requirements, in a trophic point of view for example, as well as boundary in local distribution in the southern part of the Bay of Biscay. Thus, monitoring of their distribution and abundance should be a relevant indicator of environmental change. If the presence of individuals is relatively easy to implement, monitoring in terms of abundance are more complex to develop to obtain representative data in coastal areas. The mobile character of the individual and their high location variability based on fluctuating environmental conditions is a challenge that needs to be considered. Interest concerns both the development of their number and their migration to the north for species in northern limit, and/or disappearance for species in southern distribution limits. Moreover, acquisition of knowledge on the taxonomy of local species is a way to improve biodiversity knowledge and assessment of global change as climatic change.

Traditional part-time grazing: a more sustainable sheep milk and cheese production in the Basque Country

[EN] The concept of sustainability when referring to food production rests, in general, on 3 main aspects: 1) respect for the environment; 2) economic and social benefits for all involved in production; and 3) production of sufficient quantity of quality food at an accessible price. In this contribution we focus on the main aspects of the traditional sheep's milk and cheese production (under the Denomination of Origin Idiazabal Cheese) in the Basque Country that contribute primarily to its sustainability. It is based on the local latxa or carranzana breeds of sheep, adapted to the mountainous terrain. The sheepherder takes advantage of local resources to reduce management costs by combining indoor dry forage and concentrates with outdoor grazing throughout lactation, according to local pasture availability, and thus avoiding having to buy large amounts of feed. This system facilitates recycling of manure, fertilising pastures and forest at the same time. Use of local breeds helps maintain biodiversity of sheep breeds. Cheese is produced industrially (44.5% of the total cheese produced in 2008) from milk of many flocks, or artisanally (38.3%) by the sheepherders with the milk from their own flocks. Transforming their own milk into cheese is advantageous for the following reasons: 1) higher economic returns as compared to selling the milk to cheese factories because cheese price directly sold to consumers is more competitive than industrial cheese sold in supermarkets; 2) increases the value of women's work (over 80% of the cheese makers are women) in the community and their self-esteem; 3) it creates rural jobs and contributes to rural development; 4) we have demonstrated both with experimental and commercial flocks that part-time grazing allows the sheepherder to obtain high yields of milk, and cheese, of high nutritional and functional quality. Currently a less sustainable, intensive sheep's milk production with foreign, imported breeds kept indoors constantly is gaining favour among milk producers because of its perceived higher economic profitability.

Trammel net selectivity studies in the Algarve (southern Portugal), gulf of cadiz (Spain), Basque coutry (Spain) and cyclades islands (Greece)

Trammel net fisheries were studied in four areas: the Cantabrian Sea (Basque Country, Spain), the Algarve (Southern Portugal), the Gulf of Cádiz (Spain) and the Cyclades Islands (Greece). Surveys were carried out in order to identify trammel net métiers and to characterise the gear used. Trammel nets were among the most important gears used in the small-scale fisheries, with up to 9 different métiers identified in each area. The most important métiers in the Algarve and the Gulf of Cádiz were those for cuttlefish (Sepia officinalis) and soles (Solea senegalensis, Microchirus azevia, Synaptura lusitanica). In the Cantabrian Sea, sole (Solea vulgaris), shellfish (several species) and scorpion fish (Scorpaena spp.) métiers dominated while a variety of species where targeted in the multi-species trammel net fishery in the Cyclades. In each area, experimental trammel nets of six different types (combinations of 2 large mesh outer panel sizes and 3 small mesh outer panels) corresponding to the most common métier, were constructed and fishing trials carried out on a seasonal basis (4 seasons in the Cantabrian Sea, Algarve and Cyclades and 2 in the Gulf of Cádiz) using chartered commercial fishing vessels. Overall, 271, 360, 185 and 185 km of trammel nets were fished in the experimental fishing trials in the Cantabrian Sea, Algarve, Gulf of Cádiz and Cyclades Islands respectively.
