Jehasse, Jean et Laurence (2001): Aléria. Nouvelles données de la nècropole.

La publicación por Jean y Laurence Jehasse en 1973 de la obra La Nécropole préromaine d'Aléria: 1960-1968 constituyó un hito en la historia de la investigación protohistórica en el ámbito del Mediterráneo. Junto a la necrópolis de La Spina (Italia), Aléria constituyó un punto de referencia clave para el estudio de las influencias de la sociedad colonial greco-focea sobre las comunidades indígenas en Córcega y, por extensión, en el Mediterráneo occidental, así como un corpus de consulta y análisis inexcusable para la identificación de las tipologías materiales de origen griego en la esfera colonial y comercial del extremo Occidente. Recordemos que, en esa fecha, los investigadores en la península Ibérica trabajaban esencialmente a partir de las publicaciones de J.D. Beazley (que no recogían la problemática de las series peninsulares) y, muy especialmente, con la obra Las cerámicas griegas en la península 1bérica de Gloria Trías, aparecida en 1968. Cabría esperar hasta 1977, en que Marina Picazo publicó Las cerámicas áticas de Ullastret, para contar con una monografía específica de las producciones griegas en un yacimiento ibérico.

La restitution archéologique comme modèle: le cas espagnol

Voici une réflexion autour des restitutions archéologiques et de leurs fonctions du point de vue de la recherche et du point de vue pédagogique. Nous abordons quelques cas méthodologiques propres à l’Espagne, pays où la tendance dominante est à la simple présentation des ruines, protégées ou restaurées suivant des critères d’intervention minimale. Néanmoins, plusieurs expériences de reconstruction ou reconstitution sur place ont été mises en place dans des années 1990. Plus précisément, ces expériences correspondent à deux modèles différents : la restitution sur place et la réplique. Quant au modèle de transfert, il n’a pas été adopté pour la restitution des sites archéologiques, mais il existe de nombreux exemples de monuments médiévaux et d’époque moderne qui ont été déplacés de leur emplacement d’origine.

Selection response of growth rate in rabbits for meat production

Genetic and environmental trends in 2 lines of rabbit (B and R) selected on individual weight gain (WG) from weaning (4 wk) to slaughter (11 wk) were estimated using mixed model methodology. Line B was derived from the California breed and line R was a synthetic of stock of different origin. The data were collected from a single herd and comprised 7 718 individuals in line B and 9 391 in line R, the lines having 12 and 9 generations of selection respectively. Realized responses in the 2 lines were 2.7% and 2.2% of the initial mean per year respectively and showed that selection on WG was effective but was less than expected. Selection on slaughter weight (SW) and effects of selection on other economic traits are discussed. It is concluded that selection on either WG or SW is a simple method for improving growth rate in rabbit sire line stocks.

Empirical models for predicting the production of wild mushrooms in Scots pine (Pinus sylvestris L.) forests in the Central Pyrenees

Mushroom picking has become a widespread autumn recreational activity in the Central Pyrenees and other regions of Spain. Predictive models that relate mushroom production or fungal species richness with forest stand and site characteristics are not available. This study used mushroom production data from 24 Scots pine plots over 3 years to develop a predictive model that could facilitate forest management decisions when comparing silvicultural options in terms of mushroom production. Mixed modelling was used to model the dependence of mushroom production on stand and site factors. The results showed that productions were greatest when stand basal area was approximately 20 m2 ha-1. Increasing elevation and northern aspect increased total mushroom production as well as the production of edible and marketed mushrooms. Increasing slope decreased productions. Marketed Lactarius spp., the most important group collected in the region, showed similar relationships. The annual variation in mushroom production correlated with autumn rainfall. Mushroom species richness was highest when the total production was highest.
