Ethnobotanical survey of medicinal plants used for treating diabetes in Agadir Ida Outanane region, Southwestern Morocco
(2020-01-01) Ouhaddou H.; Alaoui A.; Laaribya S.; Ayan S.
In Morocco, diabetes affects 6.6% of men and women nation-wide and is higher in urban areas. Medicinal plants are used commonly by local people of Morocco for treating diabetes. The aim of this study was to identify plants species used for curing diabetes in the Agadir Ida Outanane region, Southwest Morocco. Data were collected by semi-structured and structured interviews. 400 interviews were conducted with knowledgeable villagers. The obtained data were analyzed through fidelity level (FL: 0-100%), use value (UV) and relative frequency of citation (RFC: 0-1). This ethnobotanical survey has identified 22 species belonging to 14 families distributed. The most represented families are Lamiaceae and Asteraceae. Three plants species, Cladanthus mixtus (L.) Chevall, Pulicaria mauritanica Batt., and Salvia aegyptiaca L., are mentioned for the first time for traditional treatment of diabetes. The most frequently cited plant species are Argania spinosa (L.) Skeels, Cistus creticus L., Globularia alypum L., Olea europaea L. This survey shows that traditional medicine is still used and constituted a very rich heritage in Agadir Ida Outanane region. The collected data may help for archiving and conservation of traditional knowledge on the use of medicinal plants in the study area. In addition, it forms a basis for preliminary information required for future phytochemical investigation on the most used plants.
Modelling spatial distribution of endemic Moroccan fir (Abies marocana Trabut) in Talassemtane National Park, Morocco
(2021-01-01) Alaoui A.; Laaribya S.; Ayan S.; Ghallab A.; López-Tirado J.
Moroccan fir (Abies marocMoroccan Abies marocana Trabut) located in Talassemtane National Park, is endemic species of the Moroccan Rif, classified as "endangered" in the IUCN Red List of Threatened Species. Since the beginning of the last century, this species has suffered 70% habitat loss. However, despite its bioecological, economic and social importance, Moroccan fir has received little attention from researchers. Determining the potential area under current topographic and climatic conditions is a very important step to develop conservation and sustainable management strategies for this endangered endemic species. For this purpose, the potential distribution of Moroccan fir using the maximum entropy approach (MaxEnt software 3.4.1) is presented in this work. The developed models showed an excellent success level (96%). Environmental and topographic variables were obtained from the WorldClim project 2.1 database. Our results showed that the main variables conditioning the presence of A. marocana were the average temperature of the warmest quarter and the maximum temperature of the warmest month. The potential area represents a gain of 227% compared to the current distribution of the Moroccan fir forest. Suitable areas are provided allowing management for afforestation programs and carbon sequestration in Talassemtane National Park, Morocco.
Prediction by maximum entropy of potential habitat of the cork oak (Quercus suber L.) in Maamora Forest, Morocco

In this paper, the maximum entropy (MaxEnt) algorithm was applied to estimate the current and potential distributions of cork oak (Quercus suber L.) in the Maarmora forest of Morocco to provide a basis for its conservation under climate change conditions in the Mediterranean basin. A total of 1,428 field-based spatial records of cork oak locations were used (altitude and 19 bioclimatic environmental variables) to model the potential distribution of the cork oak. The adjusted model had a good predictive quality (area under the curve=0.81). Precipitation during the wettest quarter of the year, seasonality in precipitation, altitude, and seasonal variations in temperature were the key factors determining the distribution of the cork oak in the Maamora forest. Most areas with currently suitable conditions for cork oak were located in the western and central Maamora forest regions, which enjoy a humid bioclimate and receive significant sea spray from the Atlantic Ocean. Moving away from the ocean, the humidity decreases, and the temperature increases, such that the cork oak faces difficulties in adapting and regenerating. The results can be used to identify the high-priority areas for cork oak restoration and conservation of this s ecies a ainst the ex ected im act of climate chan e
