Commented distributional list of the Reptiles of Mauritania (West Africa)  [cached]
Padial, J. M.
Graellsia , 2006,
Abstract: This is the first comprehensive review of the reptiles of Mauritania. It includes distributional information and comments. Mauritania harbors 86 species of reptiles belonging to 21 families. Among these families, Colubridae and Lacertidae are the most diverse, with 14 and 13 species respectively. Other families, such as Agamidae, Gekkonidae, Scincidae or Viperidae are also well represented. Among the 80 continental species, 47.5% are Saharan, 33.8% Afrotropical, 16.2% Sahelian and 2.5% Mediterranean. The marine turtles form another important group, with six species. Eight species are excluded from the country list because of old identification errors, there is not enough evidence of their presence or due to changes in political borders. Among the species expected to occur in Mauritania, at least nine may occur in Saharan environments, 13 in the Sahel savannah and two may have been introduced. Esta es la primera lista de reptiles comentada con datos de distribución para la República Islámica de Mauritania. La fauna de reptiles de Mauritania se compone de 86 especies pertenecientes a 21 familias. Entres ellas, Colubridae y Lacertidae son las más diversas, con 14 y 13 especies respectivamente. Otras familias como Agamidae, Gekkonidae, Scincidae y Viperidae también son representativas. Entre las 80 especies continentales el 47.5% son de distribución sahariana, el 33.8% afrotropical, el 16.2% sahelianas y el 2.5% mediterráneas. Las tortugas marinas, con seis especies, es otro grupo importante. Ocho especies no han sido incluidas en la lista debido a que se trataba de viejos errores de identificación, por carecer de suficiente evidencia o debido a la redistribución de las viejas fronteras políticas. Entre las especies potencialmente presentes, al menos nueve de ellas se esperan para las zonas saharianas, trece para las sabanas del Sahel, y dos podrían haber sido introducidas.

Abstract: The aim of our study was to determine epidemiological, clinical and therapeutic profile of colorectal cancers in Mauritania. Patients and Methods: It was a retrospective multicentric study conducted over 5 years in Nouakchott National Hospital Centre and in private clinics of Mauritania. All cases of colorectal cancers histologically confirmed were included. The Astler and Coller classification was used to classify lesions by level of extension. Results: 225 patients were included with a sex ratio (M/F) of 1.39, an average age of 52.3 years. Location of the lesion was rectal (37.7%) and colonic (62.3%). Clinical manifestations were dominated by rectal bleeding (26.9%), occlusive syndrome (16.5%) and transit disorders (11.6%). Endoscopic lesions were of stenosing (45.2%), ulcero-burgeoning (39%), ulcerous (7.5%) and burgeoning (4.7%) types. Histological profiles were adenocarcinoma (88.9%), carcinoma (3.1%) and lymphoma (2.6%). The work-up for extension revealed metastasis in 33.6% of cases. These were stage B (49%) and C (36%) among the 95 cancers that received the Astler and Coller classification. The treatment was curative (80.83%) and palliative (19.16%). Conclusion: Colorectal cancer is a reality in Africa. However, its diagnosis still remains delayed, which increases the prognosis, hence the need to promote screening tests.
Analysis of Mauritania’s legislative elections after the 2005 coup  [PDF]

Revista CIDOB d'Afers Internacionals , 2009,
Abstract: This article presents a brief analysis of the contributions made by political science to the party systems and to the holding of elections in African countries. The aim is to apply theories on the electoral and party system in the Mauritanian elections held in November 2006, following the 2005 coup. The application of the Laakso and Taagapera formula to determine the effective number of parliamentary parties highlights the change taken place in Mauritania. Under the dictatorship of Ould Taya, the party system was by nature dominating and authoritarian. The 2006 elections, meanwhile, were notable for the fact that they were organised using a multi-party system. Meanwhile, the coup in August 2008 has highlighted the fact that this type of mathematical formula is not capable of covering the entire complex reality of Mauritania politics.
Methane emissions from the upwelling area off Mauritania (NW Africa)

Abstract: Coastal upwelling regions have been identified as sites of enhanced CH4 emissions to the atmosphere. The coastal upwelling area off Mauritania (NW Africa) is one of the most biologically productive regions of the world's ocean but its CH4 emissions have not been quantified so far. More than 1000 measurements of atmospheric and dissolved CH4 in the surface layer in the upwelling area off Mauritania were performed as part of the German SOPRAN (Surface Ocean Processes in the Anthropocene) study during two cruises in March/April 2005 (P320/1) and February 2007 (P348). During P348 enhanced CH4 saturations of up to 200% were found close to the coast and were associated with upwelling of South Atlantic Central Water. An area-weighted, seasonally adjusted estimate yielded overall annual CH4 emissions in the range from 1.6 to 2.9 Gg CH4. Thus the upwelling area off Mauritania represents a regional hot spot of CH4 emissions but seems to be of minor importance for the global oceanic CH4 emissions.

Abstract: Coastal upwelling regions have been indentified as sites of enhanced CH4 emissions to the atmosphere. The coastal upwelling area off Mauritania (NW Africa) is one of the most biologically productive regions of the world's ocean but its CH4 emissions have not been quantified so far. More than 1000 measurements of atmospheric and dissolved CH4 in the surface layer in the upwelling area off Mauritania were performed as part of the German SOPRAN (Surface Ocean Processes in the Anthropocene) study during two cruises in March/April 2005 (P320/1) and February 2007 (P348). During P348 enhanced CH4 saturations of up to 179% were found close to the coast and were associated with upwelling of South Atlantic Central Water. An area-weighted, seasonally adjusted estimate yielded overall annual CH4 emissions in the range from 0.7 to 1.4 Gg CH4. Thus the upwelling area off Mauritania represents a regional hot spot of CH4 emissions but seems to be of minor importance for the global oceanic CH4 emissions.
Caracterización fisicoquímica del yeso natural de Mauritania

Materiales de Construccion , 1998,
Abstract: Gypsum from "Nderhamcha", a region in Mauritania, has been studied through three techniques: thermo-gravimetry, thermo-differential analysis, and X ray diffraction. It has been proved that the dehydration of this material happens in two stages, characterized by the closeness of their temperature. The thermal study as certains the two transformations due to the gypsum dehydration and those due to soluble and insoluble anhidrite. El yeso de Mauritania, de la región "Nderhamcha", ha sido estudiado a través de tres técnicas instrumentales: termogravimetría, análisis térmico-diferencial y difracción de rayos X. Se comprueba que la deshidratación de este material se efectúa en dos etapas, caracterizadas por temperaturas muy próximas. En el estudio térmico se comprueban las dos transformaciones debidas a la deshidratación del yeso y las debidas a la anhidrita soluble e insoluble.
