“…The frequency of occurrence of a species is expressed as a percentage ratio of the number of samples where the species is recorded to the total number of samples taken (Dajoz, 1996). Species with a frequency greater than or equal to 50% are called constants, those with a frequency between 25% and 50% are called accessories, while species with a frequency less than or equal to 25% are called accidental.…”

“…Rivers are a crucial component of the landscape and constitute complex hydrosystems that involve the production, storage, transformation, and transportation of matter and energy under varying abiotic conditions (Battin et al, 2023). Macrophytes play a pivotal role in the functioning of rivers by providing habitats and shelters for various communities of organisms including periphyton (de Matos Costa et al, 2022), invertebrates such as zooplankton and molluscs, and vertebrates like fish and waterbirds (Cunha et al, 2019; Quirino et al, 2022). Additionally, they affect flow velocity (Shi et al, 2023), and contribute to the complexity and functional diversity of the aquatic ecosystem.…”

The critical role of macrophytes in aquatic environments cannot be overstated, but little attention has been paid to macrophytes in Moroccan rivers. This study aims to investigate the environmental factors that affect the presence and distribution of macrophytes in the Hydrological Basin of Sebou (HBS) in Morocco. The study focused on 39 hydrological stations, distributed across the five hydro‐ecoregions of the basin. The results show that the number of aquatic species is limited and significantly lower than that of riparian species, which are more diverse. Analysis of similarity (ANOSIM) revealed that there is a significant difference in the riparian species communities between the various hydro‐ecoregions (R = 0.1853, Bonferroni corrected α = 0.0022). However, when only aquatic species were considered, ANOSIM showed no significant difference (R = 0.05524, Bonferroni corrected α = 0.1453), and the results were confirmed by the PERMANOVA test. Furthermore, ANOSIM did not reveal a clear difference in the composition of aquatic species between stations with low and high nutrients (R = 0.01348, p = 0.4245). The Student's t‐test also showed no significant difference in the variation of riparian and aquatic species numbers between the two groups (all species combined: t = 0.1639, p = 0.8723; riparian species: t = 0.4740, p = 0.6434; aquatic species: t = 0.9869, p = 0.3417).These findings highlight the need for further research into environmental factors limiting aquatic species diversity and nutrient thresholds affecting macrophyte abundance. Understanding these elements is crucial for addressing species distribution constraints and elucidating nutrient dynamics that influence macrophyte populations, enriching ecosystem management and conservation strategies.
