Oued Qarya is a left-bank tributary of Oued Zloul (Sebou basin). Its basin drains an area of 323 km 2 from the northwestern slope of the Middle Atlas, folded in the province of Sefrou. These are heterogeneous geological terrains of the Lower and Middle Jurassic, dominated by the carbonate rocks of Lias (the mountain of the folded Middle Atlas). In...

Rivers play a vital role in our ecosystems, providing fresh water, supporting rich biodiversity, and contributing to human well-being. However, in the face of climate change and intensive human activities, the sediment load in rivers can reach critical levels, presenting a complex set of challenges that require immediate action. The increased sedim...

Moroccan wetlands host up to half a million wintering birds and provide a stopover for tens of thousands of migrants, while they are inhabited by few nesting species. Most of this avifauna prefers to use the large coastal wetlands or reservoirs, while many species are dispersed across hundreds of small inland wetlands of various types. In this stud...

This study aimed to explore the diversity of natural landscapes, faunae, florae, and touristic infrastructures in Taza province and their attractiveness to visitors. Equally, visitors and local populations were interviewed on the socioeconomic activities in the study area. Field visits were realized to delimit the ecosystems, road network, and infr...

This thesis work contributes to the hydro-morphodynamic and ecological characterization of rivers in the Middle Atlas and Prerif: a case study of the Bouhellou and Oued Amlil. river systems. The methodology adopted follows a systemic approach based on a multiscale study of the hydrological system, including the watershed, valley, section, and morph...

This review attempts to highlight the past and current status of ecotourism in Morocco, investigate its committed as an essential sustainable product, and make recommendations to develop this sector. A deep electronic bibliographic search on Google Scholar, research engines, and databases including Scopus, Science Direct, PubMed, and Hindawi betwee...

Geosites constitute a significant natural resource for ecological use and sustainable development in Morocco, and thus, their geological characterization and accessibility are of crucial importance. In this study, we investigated the geological structures, historical status, and accessibility of four potential geosites in the High Atlas of Morocco....

The identification of migration dates and wintering zones for migratory birds are key elements for the understanding of the Afro-Palearctic migration system. From 2015 to 2022, a large scale survey of Turtle Doves Streptopelia turtur, a vulnerable species, was established in Northwest Africa, including Morocco, Algeria, and Tunisia. We monitored mi...

Wadi Bouhellou is a small stream that drains the northern slope of the Eastern Middle Atlas. Its catchment area (312km2) contains three contrasting lithological and geomorphological domains which are respectively from upstream to downstream: the Paleozoic mountainous massif of Tazekka, the carbonated causse of Tahla and the alluvial plain of the so...

Plants are exposed to a variety of abiotic factors during their growth, such as climatic conditions and soil qualities. These factors have varying effects on the physiological and morphological characteristics of plant species. The present study was aimed at evaluating the physiological and morphological responses of Cedrus atlantica, Pinus halepen...

In this study, we investigated the avian diversity and threatening factors in five peri-urban sites around Fez city (Morocco) for 2 years (2018–2019). The study hosted 131 avian species, including 64.88% breeding species, 19.84% migrant winterers, and 11.45% migrant breeders. Five species of conservation concern such as the vulnerable European turt...

La présente étude porte sur une partie drainée par l'Oued Bouhlou, bassin versant de Sebou, moyen atlas septentrional. Elle a pour objectif d'étudier la variabilité pluviométrique, détecter les différentes ruptures et montrer les tendances générales des précipitations. Cette étude est fondée sur les séries chronologiques des précipitations cumulées...

This study evaluated of the impact of wildfires, burned areas and affected species, for the first time, in Fez, Sefrou and Boulemane provinces located in the Middle Atlas Mountains of Morocco. Data collected from field surveys from 2000 to 2020 and GIS-based aggregation functions were used to produce spatial distribution maps and to show the evolut...

The identification of water source distribution, the influence of geomorphological structures, and climatic conditions on their functioning in North Africa is a decisive issue, particularly because of the aridity dominating the area. Field visits, geological maps, and open-source GIS were used to document the diversity and distribution of water sou...

Analysis of biological diversity in woody habitats is crucial for the implementation of suitable conservation policies. We carried out monthly field visits using the point count method for avian species and walked-transect surveys for mammals and reptiles from January 2018 to December 2021 in Fez, El Hajeb and Sefrou, central Morocco. The studied s...

of the Oued Bouhellou Valley (Morocco): remarkable diversity, five new breeding cases and mapping of nesting sites. Zoology and Ecology 32(1), 36-48. Abstract. In this study, we surveyed and documented diversity and nesting of avian species and their foraging and breeding resources along the Oued Bouhellou watershed (North-Eastern Morocco). A total...

Interactions between co-occurring species, including competition and predation, comprise critical processes regulating local community structure, habitat use, and diversity. We monitored nesting habitats, breeding chronology, and reproductive success rates to describe the patterns of spatiotemporal organization of three co-habiting species: the 'na...

In this study, we described the temporal and spatial patterns of wildlife-vehicle collisions in Dakhla-Laayoune regions, using counts from cars for two years (2018–2021). A total of 462 roadkills were documented (monthly average of 0.075 roadkills/km), comprising 16 species, including mammals (residents), reptiles (residents), and birds (residents...

Investigations of niche splitting in the European Turtle dove (Streptopelia turtur) have primarily addressed feeding habitats and foraging features, and been limited to conspecific species, counting Laughing dove and Wood pigeon. The recent degradation of natural and suitable habitats for Turtle doves, particularly in North Africa would push this s...

Studies of niche segregation among avian species have mostly addressed food sites and foraging behavior, while partitioning relative to nesting sites differentiation has been little analyzed. The recent degradation and loss of suitable habitats have upraised concerns toward their effects on the distribution and evolution of ecological niches, parti...

e European Blackbird (Turdus merula) is a widespread species. In Morocco, available knowledge on this species is limited to a few descriptive pieces of information with no detailed data provided. With climate change and the intensification of agricultural activities, the study of the breeding performances of this species is indispensable for manage...

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 ec...
