Labiatae checklist for Andalusia (Southern Spain) and Rif (Northern Morocco)

. Labiatae checklist for Andalusia (Southern Spain) and the Rif (Northern Morocco). The taxa of Labiatae from Andalusia (Southern Iberian Peninsula) and the Rif (Northern Morocco) are included in a checklist, which has about 262 taxa, belonging to 28 genera and 5 subfamilies, representing almost 25% of total Mediterranean Labiatae taxa and c. 70% of total strict Labiatae Mediterranean genera. Nepetoideae with 17 genera is the richest subfamily; Ajugoideae (Ajuga genus), Teucrioideae (Teucrium genus) and Scutellarioideae (Scutellaria genus) are monogenerics. In this biogeographical region, 23 genera and about 70 species are common to both Andalusia and the Rif (about 88% of all genera and 30% of all taxa). Teucrium, Sideritis Satureja and allied genera, Salvia and Mentha, are the most widespread, representing almost 50% of the total taxa. The importance of the Labiatae family in the Andalusia and the Rif regions is reflected by the fact that they make up c. 20% of all taxa, while 25 of the total number of genera are distributed in the Betic-Rif Mountains. In addition, these mountains, are themselves the richest and best endowed regions of the Andalusia and the Rif, with the greatest concentration of endemic species (c. 65% of total endemisms)

Diversité floristique du Parc National du Haut Atlas Oriental et des Massifs ayachi et Maâsker (Maroc).

Diversité floristique du Parc National du Haut Atlas Oriental et des massifs Ayachi et Maâsker (Maroc). Etant donné la rareté des études sur le Parc National du Haut Atlas Oriental et les massifs Ayachi et Maâsker, les connaissances sur la diversité floristique de ces régions, très accidentées, étaient très insuffisantes et fragmentaires. Actuellement la flore vasculaire du Parc, jbels Ayachi et Maâsker est estimée respectivement à 227, 140 et 96 espèces; la flore rare, menacée et/ou endémique constitue une part importante. Le nombre d�endémiques dans le Parc (espèces et sous espèces) représente 6.8 % de l�ensemble des endémiques marocaines. Ce nombre est très important dans l�Ayachi avec 7.5 %. Dans le Maâsker, le nombre d�endémiques est évalué à 3.9 % de l�ensemble des endémiques marocaines. La flore rare (espèces et sous-espèces) est représentée par 3.6 % de la flore totale du Parc, 4 % de la flore totale du jbel Ayachi et 4 % de la flore totale du jbel Maâsker. Par contre le taux de la flore très rare est faible, respectivement de l�ordre de 1.9 %, 2 % et 2.4 %.Flora diversity of the National Park of the Eastern High Atlas and the massifs Ayachi and Mâasker (Morocco). Considering the rare studies on the Eastern High Atlas National Park, Ayachi and Mâasker mountains, the knowledge on the flora diversity of these regions were very insufficient.Their flora is estimated currently 227, 140 and 96 species. The rare flora, threatened and/or endemic constitutes an important part. The number of endemics in the Park (species and subspecies) represents 6.8% of the endemics of Morocco. This number is very important in Ayachi (7.5%). In Maasker, the number of endemics is about 3.9% of the endemic of Morocco. The rare flora (species and subspecies) in the Park, Ayachi and Maasker is represented respectively by 3.6%, 4%, and 4%. On the other hand the very rare flora is poor respectively 1.9%, 2% and 2.4%

ENSINO SUPERIOR EM MARROCOS, UMA NOVA GERAÇÃO DE ESTUDANTES SEM PROJETO DE CONCLUSÃO DE CURSO: EXPECTATIVAS E IMPACTO PÓS COVID-19

A new pedagogical engineering plan is being implemented in universities by Morocco's Ministry of Higher Education, Scientific Research and Innovation, by the start of the next academic year 2023-2024 in line with ESRI PACT 2030. The Final Year Project, a common practice in Moroccan higher education, has so far allowed students to apply their knowledge and skills in scientific research, promoting more equitable outcomes. However, the National Committee for Coordination of Higher Education has approved the plan to cancel it from bachelor degree programs in Morocco, which will be carried out by the next university year, raising new questions and concerns amongst the students. This paper aims to investigate the perceived importance of Final Year Projects for Moroccan students, measure their readiness to graduate with a bachelor degree without it and study the expected impact this would have on future generations' education journey.O Ministério do Ensino Superior, da Investigação Científica e da Inovação de Marrocos está a implementar um novo plano de engenharia pedagógica nas universidades, até ao início do próximo ano letivo de 2023-2024, em conformidade com o PACT 2030 da ESRI. O Projeto de Fim de Ano, uma prática comum no ensino superior marroquino, tem permitido até agora que os estudantes apliquem os seus conhecimentos e competências na investigação científica, promovendo resultados mais equitativos. No entanto, o Comité Nacional para a Coordenação do Ensino Superior aprovou o plano para o cancelar dos programas de licenciatura em Marrocos, o que será levado a cabo no próximo ano universitário, levantando novas questões e preocupações entre os estudantes. Este artigo tem como objetivo investigar a perceção da importância dos Projectos de Fim de Curso para os estudantes marroquinos, medir a sua disponibilidade para se licenciarem sem este tipo de projeto e estudar o impacto esperado que isto teria no percurso educativo das gerações futuras

CHEMICAL COMPOSITION OF THE ESSENTIAL OIL OF CLADANTHUS SCARIOSUS(ASTERACEAE) WILD GROWN IN MOROCCO

Cladanthus Cass. [Syn. Ormenis (Cass.) Cass.] is a genus of the family Asteraceae, endemic to the Mediterranean region and related to the tribe Anthemideae (1). It comprises 15 species including C. scariosus (Ball) Oberpr. & Vogt [Bas. Santolina scariosa; Syn. Ormenis scariosa Litard. & Maire] from Morocco where is concentrates 1/3 of the species of the genus (2). Some of these are perennial, suffruticose and strongly aromatic plants. C. mixta (L.) Chev. is used in Morocco as chamomile and this is commonly called Moroccan chamomile. In the same country, C scariosus is fairly common in open places, on sandstone substrates (3) and is characterized by a strong aromatic character, this has motivated the authors – some of which were previously occupied by other species of the same genus (4) – to undertake such study phytochemical. In this study, the authors present the results of chemical composition of the essential oil of Cladanthus scariosus wild grown in many regions of Morocco (5). Hydrodistillation of C. scariosus aerial parts, collected on the thermo-mediterranean belt of the central High Atlas – Oukeimeden, from Marrakech to Quarzazate – during the flowering phase gave a pale yellow oil. Overall, sixty-four compounds were identified, representing 92.7% of the total components. The main class of the oil was represented by sesquiterpene hydrocarbons (39.8%) with germacrene D (20.7%) as the most abundant component of the class and of the oil. Monoterpene hydrocarbons, oxygenated monoterpenes and oxygenated sesquiterpenes were present in similar amount (14.8%-15.1%). In these classes the main products were α-pinene (4.8%) and sabinene (6.9%) among the monoterpene hydrocarbons, (E)-chrysanthenyl acetate (8.3%) among the oxygenated monoterpenes and τ –muurolol (4.2%) and (E,E)-farnesyl acetate (3.9%) among the oxygenated sesquiterpenes. It is also noteworthy the good presence of chamazulene (7.1%)

Chorological and conservation status of the endemic cypress, Cupressus atlantica Gaussen, in the High Atlas (Morocco)

18 p. ; tablas, mapas, gráf.We present a study of the distribution, ecology and conservation status of Cupressus atlantica, an endemic tree of the High Atlas (Morocco). The main populations of this species grow in a reduced area along the N’Fiss valley in the Central High Atlas and are gradually receding. Particular populations are increasingly fragmented and the total area covered by the cypress woodland has decreased to less than a third of the surface occupied in the 1930s. Overgrazing reduces the woodlands’ regenerative capacity, and the exploitation of the wood, linked to traditional uses by the rural society of the N’Fiss valley, directly reduces the number of trees. Great efforts being made to protect the species by the Haut Commissariat aux Eaux et Forêts are having some effect in recent years.This research was partially funded by the cooperation between the Spanish Research Council (CSIC) and the Polish Academy of Sciences (PAS).Peer reviewe

Phytosociological study of the presteppic groups ofthe National Eastern High Atlas Park and surrounding areas (Morocco)

The presteppic vegetation of the National Eastern High Atlas Park and surrounding areas (Ayachi and Masker mountains) shows 12 associations organized in 2 alliances, 2 orders and 1 class. Ephedro-Juniperetalia is the most important order with one alliance Junipero-Quercion and 12 associations. Pistacio-Rhamnetalia has one alliance Junipero oxycedri-Rhamnion atlanticae and 1 association. Phytosociological, ecological and chorological details are given for each association. Three new associations are represented for the first time; these are Buxo balearicae-Juniperetum phoeniceae, Berberido hispanicae-Ribesetum uva-crispae and Junipero communi-Prunesetum prostratae. A new status is offered for Bupleuro spinosae-Juniperetum thuriferae which was considered by Achhal (1986) to be a juniperetosum sub-association of Bupleuro spinosae-Juniperetum phoeniceae. The study shows and confirms wealth and diversity of the dition plant structures, a part of which is rightfully classified as national park. The authors also recall the problem of strong human pressure on all studied habitats and give concrete proposals for the management of the ParkLa végétation présteppique (s.l.) du Parc National du Haut Atlas Oriental et ses bordures (jbels Ayachi et Masker) montre de nos jours 12 associations qui se rattachent à 2 alliances, 2 ordres et une classe. L'ordre des Ephedro-Juniperetalia est très largement en tête avec une alliance Junipero-Quercion représentée par 12 associations. L'ordre des Pistacio-Rhamnetalia n'est représenté que par une seule association qui se rattache à l'alliance Junipero oxycedri-Rhamnion atlanticae. Pour chaque association, les aspects phytosociologiques, dynamiques et chorologiques sont présentés et discutés. Trois associations nouvelles sont décrites pour la première fois, ce sont Buxo balearicae-Juniperetum phoeniceae, Berberido hispanicae-Ribesetum uva-crispae et Junipero communi-Prunesetum prostratae. Un nouveau statut est proposé pour Bupleuro spinosae-Juniperetum thuriferae qui a été considéré par Achhal (1986) comme une sous-association juniperetosum du Bupleuro spinosae-Juniperetum phoeniceae. L'étude met ainsi en lumière et confirme la richesse et la diversité des strutures végétales de la dition dont une partie est classée à juste titre comme parc national. Les auteurs évoquent également le problème de la forte pression anthropozoogène sur tous les milieux étudiés et donnent des propositions concrètes pour la gestion du parc

Analyse de la Biodiversité floristique des zones humides du maroc. Flore rare menacée et halophile

Analysis of the moroccan wetlands floristical diversity: rare, threatened and halophilous flora. The moroccan wetlands flora shows a great floristical richness of these ecosystems, estimated at more than 670 species and subspecies (83 families) which can be supplemented by at least 272 others taxa considered rather as terrestrials but can colonize periodically these biotopes. This flora shows a rate of endemism close to 6,5 %, but the most fact is the great proportion of rare or threatened taxa (estimated at 34%). The halophilous flora was a subjet of particular comment considering the prevalence of the salt biotopes in Morocco, either by the number or the extent of the sites. It counts 115 species and subspecies distributed among 20 families
