Domicola lithodesi n.gen n.sp. (Amphipoda: Calliopiidae), inhabitant of thepleonal cavity of a South African lithodid crab

Domicola lithodesi, a new genus and species of gammaridean amphipod is described. It is placed in the family Calliopiidae. Two specimens, a male and a preparatory female, were collected in August 1990 from the pleonal cavity of the lithodid crab Lithodes ferox (Filhol, 1885), an anomuran crab caught at 300 m depth from off Namibia. The more relevant characters are: anophtalmous; body smooth, gammarid-like, male smaller than female, urosomite 1 with a prepeduncular spine; telson broad, entire, unlobed and unarmed; short rostrum; accessory flagellum scale-like, calceoli absent; lower lip without inner lobes; coxa 4 posteriorly excavated; gnathopods basic, subequal, with numerous palmar spines; dactyls on P3-7 with specialized adhesive organs; coxal gill 7 present; uropods eusirid type.

Cytotaxonomy of North African species of Delphinium L. sect. Delphinium (Ranunculaceae).

S'han estudiat els nombres cromosómics i l'estructura dels cariotipus de 15 poblacions nordafricanes de Delphinium L. sect. Delphinium. Delphinium balansae Boiss. & Reuter, amb cariotipus mes simétric, apareix com a possible ancestre perenne de la resta d'espécies annuals amb cariotipus mes asimétric i mes curt. Es proposa una reorganització taxonómica de la secció, d'on es descriuen dues series noves (ser. Macropeiala ser. nova i ser. Balansae ser. nova.) i es proposen dues combinacions noves (D. nanum subsp. alboliliaceum i D. nanum subsp. elongatum).

Diet-related buccal dental microwear patterns in central african pygmy foragers and bantu-speaking farmer and pastoralist populations.

Pygmy hunter-gatherers from Central Africa have shared a network of socioeconomic interactions with non-Pygmy Bantu speakers since agropastoral lifestyle spread across sub-Saharan Africa. Ethnographic studies have reported that their diets differ in consumption of both animal proteins and starch grains. Hunted meat and gathered plant foods, especially underground storage organs (USOs), are dietary staples for pygmies. However, scarce information exists about forager-farmer interaction and the agricultural products used by pygmies. Since the effects of dietary preferences on teeth in modern and past pygmies remain unknown, we explored dietary history through quantitative analysis of buccal microwear on cheek teeth in well-documented Baka pygmies. We then determined if microwear patterns differ among other Pygmy groups (Aka, Mbuti, and Babongo) and between Bantu-speaking farmer and pastoralist populations from past centuries. The buccal dental microwear patterns of Pygmy hunter-gatherers and non-Pygmy Bantu pastoralists show lower scratch densities, indicative of diets more intensively based on nonabrasive foodstuffs, compared with Bantu farmers, who consume larger amounts of grit from stoneground foods. The Baka pygmies showed microwear patterns similar to those of ancient Aka and Mbuti, suggesting that the mechanical properties of their preferred diets have not significantly changed through time. In contrast, Babongo pygmies showed scratch densities and lengths similar to those of the farmers, consistent with sociocultural contacts and genetic factors. Our findings support that buccal microwear patterns predict dietary habits independent of ecological conditions and reflect the abrasive properties of preferred or fallback foods such as USOs, which may have contributed to the dietary specializations of ancient human populations.

North African populations carry the signature of admixture with Neandertals

One of the main findings derived from the analysis of the Neandertal genome was the evidence for admixture between Neandertals and non-African modern humans. An alternative scenario is that the ancestral population of non-Africans was closer to Neandertals than to Africans because of ancient population substructure. Thus, the study of North African populations is crucial for testing both hypotheses. We analyzed a total of 780,000 SNPs in 125 individuals representing seven different North African locations and searched for their ancestral/derived state in comparison to different human populations and Neandertals. We found that North African populations have a significant excess of derived alleles shared with Neandertals, when compared to sub-Saharan Africans. This excess is similar to that found in non-African humans, a fact that can be interpreted as a sign of Neandertal admixture. Furthermore, the Neandertal's genetic signal is higher in populations with a local, pre-Neolithic North African ancestry. Therefore, the detected ancient admixture is not due to recent Near Eastern or European migrations. Sub-Saharan populations are the only ones not affected by the admixture event with Neandertals.

Structuration and branding of a religious tourism product: Catalonia sacra

This article aims to provide an overview of the products Catalonia has to offer in terms of religious tourism. The growing interest in this kind of tourism worldwide, and in Catalonia itself, along with the region's wealth of religious heritage (particularly connected to the Christian Church) contrast with the lack of religion-based tourism products available, which results in its absence from the region's image as a tourism destination. In view of this, the Faculty of Tourism (University of Girona), the Vic Bishopric's Albergueria-Centre for Cultural Dissemination and the Tarraconense Episcopal Conference's Interdiocese Secretariat for the Custody and Promotion of Holy Art (SICPAS) decided to address the situation with the help of funding from the Autonomous Government of Catalonia. In order to re-position Christian religious heritage in the image of Catalonia as a tourist destination, the aforementioned parties embarked upon a project to set up a series of routes throughout the region, branded under the name Catalonia Sacra

Aplicación de realidad aumentada para dispositivos móviles destinada a espacios culturales. Ejemplo de desarrollo: Museu Episcopal de Vic

Proyecto de aplicación para dispositivos móviles que utiliza la Realidad Aumentada (RA) para contextualizar obras artísticas. Es un producto pensado para museos y galerías pero también para espacios exteriores que posean elementos de valor cultural. Sin embargo, y para servir de ejemplo se ha aplicado en seis piezas destacadas del Museo Episcopal de Vic. Aunque en Europa y EE.UU. los museos ya están innovando en este terreno, en España, que es donde se enmarca el proyecto, existe una carencia de elementos de mediación cultural como estos; sobre todo en los museos de arte donde las obras acostumbran a presentarse despojadas de cualquier herramienta que proporcione información complementaria. Existe, por tanto, una descontextualización del arte que crea barreras para el entendimiento del público general. De esta situación de carencia parte el objetivo principal del producto, el de aprovechar las posibilidades de la RA para mejorar la experiencia y el diálogo entre el visitante y la obra, aportando conocimiento y fomentando el aprendizaje.
