A new species of Pseudoniphargus (Crustacea, Amphipoda) from subterranean water of northeastern Morocco: Historical biogeography and evolutionary aspects Naturalis
Abiari, A. Fakher el; Oulbaz, Z.; Messouli, M.; Coineau, N..
A new species of Pseudoniphargus, P. longiflagellum (Crustacea, Amphipoda) is described from subterranean fresh water of the Riftan region of Morocco. This species is closely related to the group P. ruffoi-P. longipes, which shares several apomorphic characters. The two-step model of colonization and evolution provides an understanding of the origin and the age of this stygobiont. P. longiflagellum is derived from marine ancestors that lived in the coastal groundwater of the Tethyan South-Rifian channel during the Miocene Tortonian period. The regression of this corridor during the late Tortonian period or at the beginning of the Messinian period may have played a major role in the evolutionary history through vicariance.

AN ANALYSIS OF IODINE DEFICIENCY DISORDER AND ERADICATION STRATEGIES IN THE HIGH ATLAS MOUNTAINS OF MOROCCO AgEcon
Oldham, Elizabeth Anne; Barrett, Christopher B.; Benjelloun, Sabah; Ahanou, Brahim.
The population of the Ounein Valley in the High Atlas Mountains in Morocco is at high risk of iodine deficiency. We investigated local children’s iodine deficiency and goiter patterns as well as food consumption habits through a household survey. Median urinary iodine content and goiter analysis both reflect moderate iodine deficiency. Total fish consumption has a statistically significant, positive effect on urinary iodine content. Fish consumption, like that of salt, is closely related to market access. Respondents are uniformly unaware of the dietary etiology of goiter. An effective strategy to reduce the high incidence of iodine deficiency disorder among children in the valley must attend to four crucial issues: fish consumption, salt iodization,...

Wahbi, Fatima; Le Loc'H, Francois; Berreho, Amina; Benazzouz, Aissa; Ben Mhmed, Abdelouahed; Errhif, Ahmed.
A study of the diet of the Atlantic horse mackerel Trachurus trachurus (Linnaeus, 1758) was carried out on the Atlantic coast of Southern Morocco, located from Cap Boujdour to Cap Blanc (26 degrees 30'N-21 degrees N latitude). This area is characterized by a permanent upwelling and is among the highly productive ecosystems of the worldwide ocean. The diet of T. trachurus was studied through qualitative and quantitative analysis of stomach contents. Samples were collected during the warm (June-July-August) and the cold seasons (November-December) in 2007 and 2008. Acoustic surveys were carried out on board of the Moroccan Amir Moulay Abdellah and the Russian Atlantida oceanographic vessels. A total of 456 stomachs were analyzed, exhibiting a diversified...

Crustal structure of the NW Moroccan margin from deep seismic data (SISMAR Cruise) ArchiMer
Jaffal, Mohammed; Klingelhoefer, Frauke; Matias, Luis; Teixeira, Fernando; Amrhar, Mostafa.
During the SISMAR cruise (spring 2001), new deep seismic data were acquired on the Atlantic Moroccan margin. The purpose of the present work is to analyse and to interpret a part of the data consisting of four wide-angle seismic profiles (4, 5, 8 and 10) recorded offshore El Jadida. Lines 4 and 5, perpendicular to the margin, show a crustal thickness of 35 km under the western Moroccan Meseta which thins progressively seaward where it reaches a minimum thickness of 10 km. The calculated velocity models show that this crust consists of two crustal layers overlain by a sedimentary cover corresponding to the post-Paleozoic sediments, characterised by a low velocity. The detailed shallow structure is obtained primarily from multichannel seismic data. Half...

Dynamic Field Experiments in Development Economics: Risk Valuation in Morocco, Kenya, and Peru AgEcon
Lybbert, Travis J.; Galarza, Francisco B.; McPeak, John G.; Barrett, Christopher B.; Boucher, Stephen R.; Carter, Michael R.; Chantarat, Sommarat; Fadlaoui, Aziz; Mude, Andrew G..
The effective design and implementation of interventions that reduce vulnerability and poverty require a solid understanding of underlying poverty dynamics and associated behavioral responses. Stochastic and dynamic benefit streams can make it difficult for the poor to learn the value of such interventions to them. We explore how dynamic field experiments can help (i) intended beneficiaries to learn and understand these complicated benefit streams, and (ii) researchers to better understand how the poor respond to risk when faced with nonlinear welfare dynamics. We discuss and analyze dynamic risk valuation experiments in Morocco, Peru, and Kenya.

Eau colorée à Lingulodinium polyedrum (Stein) Dodge, dans une zone aquacole du littoral du Doukkala (Atlantique marocain) ArchiMer
Bennouna, A; Berland, B; El Attar, J; Assobhei, O.
A red tide of Lingulodinium polyedrum occured along the moroccan atlantic coast in july 1999. Observed in the beginning of the month in the Kenitra area, it spreads with the coastal drift as far as the south of safi, passing on its way upon a sanitary monitored area. This area which is submitted to an all year round bimonthly monitoring analysis of phytoplankton, contains significant natural beds of oysters, clams and mussels, as well as shellfish farms in Oualidia and Sidi Moussa lagoons. However, during this period of bloom, there was weekly monitoring of hydrologic and climatic data associated with phytoplankton analysis to identify the causes of this bloom. This bloom occured in 17-18degreesC surface waters, temperatures which are favourable to...

Abourazzak,S; Achour,S; El Arqam,L; Atmani,S; Chaouki,S; Semlali,I; Soulaymani Bencheikh,R; Bouharrou,A; Hida,M.
Scorpion stings are a public health problem in Morocco, especially among children, who experience the most severe cases. Epidemiological and clinical findings on scorpion stings in Fez, Morocco, were evaluated in this investigation. Of 163 cases that required medical attention, 62.6% were male children. The mean age of patients was 4.8 ± 3.4 years. The mean time between stings and first medical attention was 3.36 ± 2.5 hours. Almost all cases occurred in the summer (94%) and extremities represented the most frequent sting sites (86.5%). Local pain, hyperemia, scarification, vomiting, sweating, restlessness, tachycardia and tachypnea were the observed clinical symptoms. Regarding severity, 55.2% of patients belonged to class III, followed by class II...

Epidemiological profile of snakebites in Morocco J. Venom. Anim. Toxins incl. Trop. Dis.
Arfaoui,A; Hmimou,R; Ouammi,L; Soulaymani,A; Mokhtari,A; Chafiq,F; Soulaymani-Bencheikh,R.
The present work aims to find the epidemiological profile of snakebites in Morocco through a retrospective study of 1,423 snakebite cases that occurred between 1992 and 2007. Data were obtained from medical charts of envenomation at the Poison Control and Pharmacovigilance Center of Morocco. Results revealed that 86% of the snakebites had occurred in rural areas and that males were significantly more affected than females at a sex ratio of 23:20. Furthermore, 35% of the bites happened during the summer, with a peak of 215 cases in June (15.1%). We also discovered that 67.3% of the patients were bitten during the day. The age group that comprised the most agriculturally active persons, from 20 to 44 years old, was the most affected by snakebites (551...

EU Trade Preferences for Moroccan Tomato Exports--Who Benefits? AgEcon
Chemnitz, Christine; Grethe, Harald.
The EU applies a complex system of preferences for tomato imports from Morocco. Quantities are fixed and serve as entry price quotas and tariff rate quotas at the same time. This paper provides empirical evidence of i) the existence of an economic rent under the EU preferential scheme for tomato imports from Morocco of about €24-36.5 mill. per year, and ii) the distribution of that rent. Due to the structure of the Moroccan export sector as well as the EU method of allocating import licenses, it is likely that a large part of the quota rent ends up at the Moroccan side and that a dissipation of the rent in physical rent-seeking activities is limited.

Évolution biologique de la lagune de Nador (Maroc) au cours de la période 1982-1993 ArchiMer
Lefebvre, A; Guelorget, O; Perthuisot, Jp; Dafir, Je.
The biogeological evolution of Nador lagoon over the 1982-1993 period was surveyed through water parameters, chlorophyll biomass, macrobenthos and surficial sediments. Comparison of present data with the 1982-83 ones (Guelorget et al., 1984) shows that: the general organization and functioning of the basin (water circulation, biological and sedimentological zonations) remain roughly the same, the global confinement as described by the biological zonation has slightly increased, with an extension of the high confinement zones (zones IV to VI) to the detriment of the low confinement zones, notably zones I and II, the main change has been eutrophication and a dramatic increase elf organic matter inputs and sedimentation, due to increasing urbanization and the...

Metal concentrations in sediment and Nereis diversicolor in two Moroccan lagoons: Khnifiss and Oualidia ArchiMer
Idardare, Zaina; Chiffoleau, Jean-francois; Moukrim, A; Alla, A; Auger, Dominique; Lefrere, L; Rozuel, Emmanuelle.
Metal concentrations were measured monthly during an annual cycle (December 2004 to January 2006) in the tissues of Nereis diversicolor ragworms and sediment from two Moroccan Atlantic coastal lagoons: Oualidia in the north, situated in a highly industrialised urban area and Khnifiss in the south, far from anthropogenic influences. Relatively high levels of Zn, Ag and Cd were found in the sediment of Oualidia lagoon, while Ni concentrations were shown to be high at Khnifiss. The significant metal levels at Oualidia are a result of industrial and urban discharges, coupled with discharges from adjacent phosphate ore processing plants. Trace metal concentrations in worms vary according to season; they are usually high in winter and spring, in relation to the...

Norovirus and Other Human Enteric Viruses in Moroccan Shellfish ArchiMer
Benabbes, Laila; Ollivier, Joanna; Schaeffer, Julien; Parnaudeau, Sylvain; Rhaissi, Houria; Nourlil, Jalal; Le Guyader, Soizick.
The aim of this study was to evaluate the presence of human enteric viruses in shellfish collected along the Mediterranean Sea and Atlantic Coast of Morocco. A total of 77 samples were collected from areas potentially contaminated by human sewage. Noroviruses were detected in 30 % of samples, with an equal representation of GI and GII strains, but were much more frequently found in cockles or clams than in oysters. The method used, including extraction efficiency controls, allowed the quantification of virus concentration. As in previous reports, results showed levels of contamination between 100 and 1,000 copies/g of digestive tissues. Sapoviruses were detected in 13 % of samples mainly in oyster and clam samples. Hepatitis A virus was detected in two...

Patrimony for Resilience: Evidence from the Forest Agdal in the Moroccan High Atlas Mountains Ecology and Society
Patrimony and resilience appear today as key concepts for understanding the dynamics of systems confronted with natural hazards. Nevertheless, the theoretical comparison between these concepts drawn from different epistemic approaches is lacking. Our aim is to interrelate resilience and patrimony concepts on the basis of a real example: the Agdal, a traditional forest management system in the Moroccan High Atlas. The role played by the Agdal in safeguarding the patterns of forest resource use by village communities from both external and internal conflicts, from natural hazards, and by securing a long-term supply of resource diversity is highlighted. This role shows the patrimonial character of the forest Agdal for the village communities and suggests an...
