The analysis of avian diversity and their natural ecosystems at a regional scale is the first step to understanding and classifying a specific region's ecological importance and, therefore, adopting sustainable economic activities and implementing suitable conservation measures. This study investigated the avian richness and natural ecosystems in Eastern and central High Atlas between 2015 and 2021. Transects and point-count methods were used to identify and estimate populations of birds and to delimit the nature of ecosystems. A total of 175 bird species among resident-breeders, migrantbreeders, migrant-winterers, and accidental-visitors were documented. These birds belong to 19 orders and are grouped into 51 families. Among recorded birds, 20 species were categorized as species of ectouristic interest due to their roles in birdwatching, hunting, racing sports, and trade activities. These species were observed in natural and human-made ecosystems, with the majority in wetlands. The abundance of a wide range of ecosystems and various bioclimatic stages is suggested to be behind the avian richness of these mountainous areas. Finally, these natural landscapes and their avian richness could be used for ecotouristic purposes. Visitors could profit from the view of landscapes and observation of the most iconic and rare animal species, which is suggested to increase the income for local populations and ensure the sustainable use of natural resources.

In this study, we surveyed the diversity and distribution of breeding birds in dominating habitat of Central High Atlas valleys and principal governing factors. In the point-counts method with 170 sampling points from 2018 to 2019, richness parameters and multivariate analysis were used to assess the distribution of recorded birds. We recorded 92 breeding birds of migrants (34%) and residents (68%), belonging to 34 families and 13 orders. The families of Muscicapidae (13 species), Fringillidae (8 species), and Accipitridae (7 species) were the most abundant, while the Regulidae, Malaconotidae, Acrocephalidae, Cettiidae, Pycnonotidae, Cinclidae, Oriolidae, Laniidae, Phylloscopidae, Troglodytidae, Meropidae, Coraciidae, Cuculidae, Caprimulgidae, Upupidae, and Ciconiidae, were the less observed with one bird species each. One species of conservation concern, namely the globally vulnerable Turtle dove, was recorded. On the other hand, Statistical analysis showed that bird richness was similar among forest stands, while abundance differed significantly. In contrast, both richness and abundance were statistically different among open habitats. Further, 46 species were found in Juniper stand surrounded by agricultural fields, followed by 30 species in Holm Oak stands where the density of trees, shrubs, and canopy coverage were higher, while in Black poplar stands characterised by higher trees and shrubs, and high availability of water hosted only 20 species. Rare and accidental birds dominate the forest and open lands, demonstrating the vulnerability of these habitats. This study could serve as a great reference for comparative studies of interesting birds on both slopes of the Mediterranean.

Studies incorporating the nesting behavior and ecology of parasite disease in the European turtle dove during breeding periods are rare. This research examined nest features and nesting materials in Turtle doves to characterize nest dimensions, build, and incorporate vegetation, mainly aromatic and medicinal plants. In parallel, we estimated the ectoparasite load on chicks to verify an eventual relation between odorant plants and pathogen loads. The study was carried in apple orchards at Okhaja Ait Ayach, Midelt province Morocco, during 2015 and 2016. The obtained results demonstrate that the Turtle dove constructs a medium nest, compared to its body size, using several plant species, including medicinal and aromatic species known for their toxicity against pathogens. The inhibition capacity of nesting materials is reflected in parasite loads since only 8% of chicks were infested with Columbicola columbae and Dermanyssus gallinae. Repellent materials in nests are a successful behavioral strategy for this declining game to protect nestlings against pathogens.(AU)

It has been argued that genetic diversity in crop varieties has been on the decline in recent times due to plant breeding. This can have serious consequences for both the genetic vulnerability of crops and their plasticity when responding to changes in production environments. It is, therefore, vital for plant breeding programs to maintain sufficient diversity in the cultivars deployed for multi-period cultivation. In this study, to understand the temporal genetic diversity in durum wheat, 21 improved durum wheat cultivars released in Morocco, since 1956 and five exotic cultivars currently used in crossing programs were analyzed using 13 microsatellite markers. The analysis revealed a total of 44 alleles and average genetic diversity of 0.485 with genetic distances ranging from 0.077 to 0.846 at 13 microsatellite loci in Moroccan durum wheat cultivars. All the durum cultivars of Morocco could be distinguished using the 13 microsatellite markers. The total number of alleles and unique alleles were highest in cultivars developed before 1990, decreasing in cultivars developed during the 1990s and 2000s, indicating that recent durum breeding efforts have reduced allelic richness in recent cultivars. Thus, deployment of exotic durum wheat lines in breeding programs could enhance genetic diversity in durum wheat cultivars.

The diversity of thermophilic bacteria was investigated in four hot springs, three salt marshes and 12 desert sites in Morocco. Two hundred and forty (240) thermophilic bacteria were recovered, identified and characterized. All isolates were Gram positive, rod-shaped, spore forming and halotolerant. Based on BOXA1R-PCR and 16S rRNA gene sequencing, the recovered isolates were dominated by the genus Bacillus (97.5%) represented by B. licheniformis (119), B. aerius (44), B. sonorensis (33), B. subtilis (subsp. spizizenii (2) and subsp. inaquosurum (6)), B. amyloliquefaciens (subsp. amyloliquefaciens (4) and subsp. plantarum (4)), B. tequilensis (3), B. pumilus (3) and Bacillus sp. (19). Only six isolates (2.5%) belonged to the genus Aeribacillus represented by A. pallidus (4) and Aeribacillus sp. (2). In this study, B. aerius and B. tequilensis are described for the first time as thermophilic bacteria. Moreover, 71.25%, 50.41% and 5.41% of total strains exhibited high amylolytic, proteolytic or cellulolytic activity respectively.(AU)

The Souss region in Morocco is known nationally and internationally for its essential knowledge of traditional herbal medicine and the cultural heritage of nutrition. The endemic species Argania spinosa (L.) Skeels is an important crucial plant used by the local population to treat many diseases and prepare some authentic foods. To identify the therapeutic uses of the Argan tree [Argania spinosa (L.) Skeels] and their benefits in preparing authentic foods, the survey was conducted using semi-structured questionnaires. We have achieved 450 interviews with traditional health practitioners and knowledgeable villagers. In the region of Chtouka Aït Baha and Tiznit (Western Anti-Atlas). In parallel with this survey, we collected some old local manuscripts from conventional practitioners in the region. The data obtained were analyzed using specific ethnobotanical indices such as Use Value (UV), Fidelity Level (FL), and Relative Frequency of Citation (RFC). In parallel, we analyzed the nutritional value of some authentic foods derived the argan oil (Amlou, Tagoulla, and Labsis). All 450 interviewees use the argan oil in food or for the preparation of their authentic foods derived (Amlou, Tagoulla, and Labsis); among them, 100 persons use Argan, in addition to food, in the treatment of various diseases with UV and RFC at 1.94 and 0.22, respectively. Among eight treated diseases by argan tree, the treatment of skin and subcutaneous diseases had a very highly significant value of the FL index (98%). Similarly, the analysis of the manuscripts collected in the study area revealed an ancient therapeutic use of the argan tree. The results also show that the Argan oil extracted from the seed is used to prepare authentic foods with significant nutritional value, especially Amlou.


A região de Souss em Marrocos é conhecida nacional e internacionalmente pelo seu conhecimento essencial da medicina tradicional à base de plantas e pela herança cultural da nutrição. A espécie endêmica Argania spinosa (L.) Skeels é uma importante planta crucial utilizada pela população local para tratar muitas doenças e preparar alguns alimentos autênticos. Para identificar os usos terapêuticos da árvore de argan [Argania spinosa (L.) Skeels] e seus benefícios na preparação de alimentos autênticos, a pesquisa foi realizada por meio de questionários semiestruturados. Conseguimos 450 entrevistas com profissionais de saúde tradicionais e aldeões experientes na região de Chtouka Aït Baha e Tiznit (Anti-Atlas Ocidental). Paralelamente a esta pesquisa, coletamos alguns manuscritos locais antigos de praticantes convencionais da região. Os dados obtidos foram analisados ​​por meio de índices etnobotânicos específicos, como Valor de Uso (UV), Nível de Fidelidade (FL) e Frequência Relativa de Citação (RFC). Paralelamente, analisamos o valor nutricional de alguns alimentos autênticos derivados do óleo de argan (Amlou, Tagoulla e Labsis). Todos os 450 entrevistados utilizam o óleo de argan na alimentação ou para o preparo de seus autênticos alimentos derivados (Amlou, Tagoulla e Labsis); entre eles, 100 pessoas utilizam o argan, além da alimentação, no tratamento de diversas doenças com UV e RFC a 1,94 e 0,22, respectivamente. Entre oito doenças tratadas pela árvore de argan, o tratamento de doenças de pele e subcutâneas teve um valor muito significativo do índice FL (98%). Da mesma forma, a análise dos manuscritos coletados na área de estudo revelou um antigo uso terapêutico da árvore de argan. Os resultados também mostram que o óleo de argan extraído da semente é utilizado para preparar alimentos autênticos com valor nutricional significativo, especialmente Amlou.
