Viatge al Marroc de la Secció de Geografia de la Universitat de Girona, 24-30 d'abril de 2000

A group of teachers and students of the Geography Unit of the University of Girona conducted a field trip in a part of Northern Morocco, which once belonged to the Spanish Protectorate. The visit took place between 24th and 30th April 2000. Some teachers of the University of Tetouan accompanied the group and offered comprehensive geographical explanations of the area, including physical, social and economic aspects

La Sociedad Geográfica de Madrid y el colonialismo español en Marruecos (1876-1956)

L’objectiu central de l’article és analitzar l’actitud que es manifestà a la Sociedad Geogràfica de Madrid en relació amb l’acció colonial espanyola al Marroc, des del 1876 —any de creació de la Societat— fins al 1956 —independència del Marroc i consegüent finalització del protectorat espanyol—. Així mateix, s’examinen les actuacions que dugué a terme per impulsar l’esmentat procés, els mecanismes que utilitzà per influir en la política exterior i en la societat espanyoles i les repercussions de la seva activitat

Geografía, ordenación del territorio y colonialismo español en Marruecos

L’inici de la experiència colonial espanyola en Àfrica del Nord va suposar per a la geografia l’ocasió de fer-se sentir per mitjà de la creació d’institucions i de la realització de treballs científics adreçats a donar a conèixer la importància de la presència en Marroc a una població traumatitzada per la pèrdua recent del que quedava d’un imperi colonial abans extens. Els avatars de la implantació del Protectorat espanyol van retardar la implantació l’una vertadera política colonitzadora, que va ser possible fins després de la Guerra Civil. L’africanisme dels militars, entre ells el General Franco, explica que durant la dècada dels 40 sorgiren projectes d’ordenació del territori que van tenir un caràcter pioner a l’Espanya de la postguerra, però que van ser, una vitrina de propaganda del nou règim. En aquella època, però, la geografia espanyola es va mostrar incapaç de participar en aquesta experiència a causa del seu retard institucional i acadèmic, i el domini de la ordenació del territori va quedar en mans d’altres professionals que tenien els coneixements que els faltaven als geògrafs

Programari creador i consultor de genealogia familiar

Aquest projecte es centre en el disseny d’ un programari creador iconsultor de genealogia familiar. Es tracta d'un programari per a ús individual, no col.lectiu, i sense ànimde lucre, on les dades més importants són les dels familiars. Qualsevol usuari pot crear diversesfamílies (en un mateix sistema) i associar-hi familiars. Es poden introduir molts tipus de dadespersonals, a més de poder vincular-hi els arxius i events que es desitgin. Un event és unaconteixament en la vida d'una o diverses persones. D'aquesta manera l'usuari pot agregar moltstipus d'esdeveniments diferents als familiars i també hi ha la opció, que diferencia l'aplicació demoltes altres ja existents, d'agregar esdeveniments als events. També cal destacar que a cadafamiliar, arxiu i event pot associar-se un lloc (poblacio, regió i estat) i d'aquesta forma la informaciótotal que es pot generar, encara és encara més completa. La possibilitat de crear llocs nous és forçaàmplia. Finalment l'usuari podrà associar els diferents familiars segons parentesc i d'aquesta formaobtenir un arbre genealògic de tota la família. Un dels aspectes més treballats a l'aplicació, ha estat que totes les dades anteriorment esmentades, poguessin ser visualitzades fàcil i ràpidament per l'usuari final. La navegació entrepantalles i les diferents opcions, han estat pensades i dissenyades, perquè l'usuari final no tingui cap dificultat, sigui quin sigui el seu nivell. D'aquesta manera, a més de la gestió possible de dades de familiars, arxius, events i llocs; la utilització de le mateixes i la creació de multitud de vistes i cerques diferents, ajuden a que el programari sigui força complet

A genealogical conceptual model using ontologies

Roughly fifteen years ago, the Church of Jesus Christ of Latter-day Saints published a new proposed standard file format. They call it GEDCOM. It was designed to allow different genealogy programs to exchange data.Five years later, in may 2000, appeared the GENTECH Data Modeling Project, with the support of the Federation of Genealogical Societies (FGS) and other American genealogical societies. They attempted to define a genealogical logic data model to facilitate data exchange between different genealogical programs. Although genealogists deal with an enormous variety of data sources, one of the central concepts of this data model was that all genealogical data could be broken down into a series of short, formal genealogical statements. It was something more versatile than only export/import data records on a predefined fields. This project was finally absorbed in 2004 by the National Genealogical Society (NGS).Despite being a genealogical reference in many applications, these models have serious drawbacks to adapt to different cultural and social environments. At the present time we have no formal proposal for a recognized standard to represent the family domain.Here we propose an alternative conceptual model, largely inherited from aforementioned models. The design is intended to overcome their limitations. However, its major innovation lies in applying the ontological paradigm when modeling statements and entities.

Jurassic sedimentary record and tectonic evolution of the northwestern corner of Africa

The history of the opening seaway from the westernmost Tethys to the Central Atlantic is traced by the analysis of the sedimentary facies development in the external Rif basin of Northern Morocco and the geological and seismic data from the Moroccan Atlantic continental margin. In the Rif basin, after the early Sinemurian, sedimentary facies dated by ammonites, foraminifers and brachiopods, indicate a progression of rapid subsidence resulting from extensional tectonic (tilted blocks, escarpment fault breccias, neptunian dykes etc.) from the N and NE to the S and SW. From the Toarcian to the Bajocian, deltas progress from the W and SW into the `'Rides sud-rifaines'' realm. From the late Bathonian to the Oxfordian, deep-sea fans develop in the external Rif. During the same period, deltaic sediments fill in the Middle Atlas basin of Eastern Morocco and progress into the external Rif. The top of the Jurassic is characterised by carbonate deposits. At the northwestern corner of Africa, the subsidence of the sedimentary basins by rifting is initiated in the late Triassic; however, at the Mazagan transect of the Atlantic continental margin, the tectonic pattern characteristic of a passive continental margin appears clearly only in the early Jurassic. At the foot of the Mazagan escarpment, the sedimentary record shows a foundering of the first bloc during early to middle Lias. A thermal uplift phase is indicated by emersion of the African margin shoulder in late Liassic, and thermal relaxation starts in the middle Jurassic. The morphology of this transect, compared with the conjugate side of the American continent is most easily explained by the uniform sense simple shear model.

Habitat, morphology and karyotype of the Saharan shrew Crocidura tarfayaensis (Mammalia : Soricidae)

The Saharan shrew Crocidura tarfayaensis Vesmanis and Vesmanis, 1980, has a limited disribution along the Atlantic coast of Sahara, south of Agadir (Morocco) through Western Sahara into Mauritania and is only known from few captures and some owl pellets. Here we report field data from the successful trapping of five specimens of C. tarfayaensis in the Guelmim region. The habitat was characterized by sand dunes along a river, with dense shrubberies of Tamarix sp., the huge grass Erianthus ravennae (Poaceae) and flat bushes of Atriplex glauca var. ifniensis (Chenopodiaceae). Morphological discrimination with C. whitakeri were examined. The chromosomes of C. tarfayaensis revealed a karyotype of 2n = 36, similar to that of the Canary shrew C. canariensis and the Sicilian shrew C. sicula. In conclusion, C. tarfayaensis seems to be a descendant of the presumed continental ancestor of the two island species.

The dynamics of Brazilian protozoology over the past century

Brazilian scientists have been contributing to the protozoology field for more than 100 years with important discoveries of new species such asTrypanosoma cruzi and Leishmania spp. In this work, we used a Brazilian thesis database (Coordination for the Improvement of Higher Education Personnel) covering the period from 1987-2011 to identify researchers who contributed substantially to protozoology. We selected 248 advisors by filtering to obtain researchers who supervised at least 10 theses. Based on a computational analysis of the thesis databases, we found students who were supervised by these scientists. A computational procedure was developed to determine the advisors’ scientific ancestors using the Lattes Platform. These analyses provided a list of 1,997 researchers who were inspected through Lattes CV examination and allowed the identification of the pioneers of Brazilian protozoology. Moreover, we investigated the areas in which researchers who earned PhDs in protozoology are now working. We found that 68.4% of them are still in protozoology, while 16.7% have migrated to other fields. We observed that support for protozoology by national or international agencies is clearly correlated with the increase of scientists in the field. Finally, we described the academic genealogy of Brazilian protozoology by formalising the “forest” of Brazilian scientists involved in the study of protozoa and their vectors over the past century.

Disentangling reasons for low Y chromosome variation in the greater white-toothed shrew (Crocidura russula).

Y chromosome variation is determined by several confounding factors including mutation rate, effective population size, demography, and selection. Disentangling these factors is essential to better understand the evolutionary properties of the Y chromosome. We analyzed genetic variation on the Y chromosome, X chromosome, and mtDNA of the greater white-toothed shrew, a species with low variance in male reproductive success and limited sex-biased dispersal, which enables us to control to some extent for life-history effects. We also compared ancestral (Moroccan) to derived (European) populations to investigate the role of demographic history in determining Y variation. Recent colonization of Europe by a small number of founders (combined with low mutation rates) is largely responsible for low diversity observed on the European Y and X chromosomes compared to mtDNA. After accounting for mutation rate, copy number, and demography, the Y chromosome still displays a deficit in variation relative to the X in both populations. This is possibly influenced by directional selection, but the slightly higher variance in male reproductive success is also likely to play a role, even though the difference is small compared to that in highly polygynous species. This study illustrates that demography and life-history effects should be scrutinized before inferring strong selective pressure as a reason for low diversity on the Y chromosome.

X-chromosome SNP analyses in 11 human Mediterranean populations show a high overall genetic homogeneity except in North-west Africans (Moroccans).

BACKGROUND: Due to its history, with a high number of migration events, the Mediterranean basin represents a challenging area for population genetic studies. A large number of genetic studies have been carried out in the Mediterranean area using different markers but no consensus has been reached on the genetic landscape of the Mediterranean populations. In order to further investigate the genetics of the human Mediterranean populations, we typed 894 individuals from 11 Mediterranean populations with 25 single-nucleotide polymorphisms (SNPs) located on the X-chromosome. RESULTS: A high overall homogeneity was found among the Mediterranean populations except for the population from Morocco, which seemed to differ genetically from the rest of the populations in the Mediterranean area. A very low genetic distance was found between populations in the Middle East and most of the western part of the Mediterranean Sea.A higher migration rate in females versus males was observed by comparing data from X-chromosome, mt-DNA and Y-chromosome SNPs both in the Mediterranean and a wider geographic area.Multilocus association was observed among the 25 SNPs on the X-chromosome in the populations from Ibiza and Cosenza. CONCLUSION: Our results support both the hypothesis of (1) a reduced impact of the Neolithic Wave and more recent migration movements in NW-Africa, and (2) the importance of the Strait of Gibraltar as a geographic barrier. In contrast, the high genetic homogeneity observed in the Mediterranean area could be interpreted as the result of the Neolithic wave caused by a large demic diffusion and/or more recent migration events. A differentiated contribution of males and females to the genetic landscape of the Mediterranean area was observed with a higher migration rate in females than in males. A certain level of background linkage disequilibrium in populations in Ibiza and Cosenza could be attributed to their demographic background.

Post-collisional Neogene magmatism of the Mediterranean Maghreb margin: a consequence of slab breakoff

A 1 200 km-long linear magmatic belt extends along the Mediterranean coast the Maghreb from Eastern Tunisia to Morocco. This belt is mainly composed of Langan calc-alkaline metaluminous to peraluminous granitoids and associated andesites/cites Central and Eastern Algeria. In Tunisia and Oranie/Western Morocco, calc alkaline activity started later (during the Serravallian) and was followed by the placement of alkali basalts and basanites since the Tortonian to the Pliocene and, in me places, the Pleistocene. Available data on the tectonic setting, petrology, age and biochemistry of this belt show that most of its striking features, e.g. (1) very low magma production rate, subduction-related geochemical imprint, extensive crustal contamination the calc-alkaline magmatism and (2) progressive magmatic change from calc-alkaline alkaline, are consistent with magma generation during a slab breakoff process as proposed Carminati et al, in 1998. The magmatism associated with this breakoff started in Central Eastern Algeria at 16 Ma, then propagated eastwards and westwards, The upward of asthenospheric enriched plume-type mantle through the tear in the downgoing first triggered melting of the overlying lithospheric mantle which had been metasomatised during a previous subduction period. Heat supply from this uprising asthenosphere may have warmed up the continental crust and made its involvement in assimilation processes easier. As the asthenosphere ascended through the `window' in the slab, partial melting occurred at the uprising boundary between asthenosphere and lithosphere, generating basalts with transitional characteristics between those of calc-alkaline and alkaline basalts. As the asthhenospheric upwelling proceeded partial:melting then occurred in the sole asthenospheric mantle, producing alkali basalts.

Do plants adjust their sex allocation and secondary sexual morphology in response to their neighbours?

BACKGROUND AND AIMS: Changes in the sex allocation (i.e. in pollen versus seed production) of hermaphroditic plants often occur in response to the environment. In some homosporous ferns, gametophytes choose their gender in response to chemical cues sent by neighbours, such that spores develop as male gametophytes if they perceive a female or hermaphrodite nearby. Here it is considered whether a similar process might occur in the androdioecious angiosperm species Mercurialis annua, in which males co-occur with hermaphrodites; previous work on a Spanish population of M. annua found that individuals were more likely to develop as males at high density. METHODS: Using a novel approach to treat plants with leachate from pots containing males or hermaphrodites of M. annua, the hypothesis that individuals assess their mating opportunities, and adjust their sex expression accordingly, was tested through an exchange of chemical cues through the soil. KEY RESULTS: For the population under study, from Morocco, no evidence was found for soil-signal-dependent sex expression: neither sex ratios nor sex allocation differed among experimental treatments. CONCLUSIONS: The results imply either that the Moroccan population under study behaves differently from that previously studied in Spain (pointing to potential geographical variation in plasticity for sex expression), or that our method failed to capture the signals used by M. annua for adjustment of sex expression.

A qualitative study about immigrant workers’ perceptions of their working conditions in Spain

Background: Spain has recently become an inward migration country. Little is known about the occupational health of immigrant workers. This study aimed to explore the perceptions that immigrant workers in Spain had of their working conditions.Methods: Qualitative, exploratory, descriptive study. Criterion sampling. Data collected between September 2006 and May 2007 through semi-structured focus groups and individual interviews, with a topic guide. One hundred and fifty-eight immigrant workers (90 men/68 women) from Colombia (n = 21), Morocco (n = 39), sub-Saharan Africa (n = 29), Romania (n = 44) and Ecuador (n = 25), who were authorised (documented) or unauthorised (undocumented) residents in five medium to large cities in Spain.Results: Participants described poor working conditions, low pay and health hazards. Perception of hazards appeared to be related to gender and job sector. Informants were highly segregated into jobs by sex, however, so this issue will need further exploration. Undocumented workers described poorer conditions than documented workers, which they attributed to their documentation status. Documented participants also felt vulnerable because of their immigrant status. Informants believed that deficient language skills, non-transferability of their education and training and, most of all, their immigrant status and economic need left them with little choice but to work under poor conditions.Conclusions: The occupational health needs of immigrant workers must be addressed at the job level, while improving the enforcement of existing health and safety regulations. The roles that documentation status and economic need played in these informants' work experiences should be considered and how these may influence health outcomes.
