An overview of Moroccan stoneflies is presented as an annotated summary of published and unpublished records from 115 localities. These records have resulted in an updated species list reflecting taxonomic corrections and noteworthy range extensions for several species. A total of 28 species, belonging to 15 genera and seven families, is now known from Morocco with the greatest diversity found in the Rif Mountains (23 species) and the lowest in eastern Morocco with three species. The majority of Moroccan stoneflies are typical Mediterranean species (86%). The Moroccan endemics comprise nine species (32% of the Moroccan fauna). The Plecoptera fauna of Morocco is compared to that of Algeria and Tunisia. Thirty-eight stonefly species are reported from the entire Maghreb region. Protonemura khroumiriensis Béjaoui & Boumaïza, 2009 is considered a synonym of P. drahamensis Vinçon & Pardo, 2006.
This study aimed to evaluate the effects of the Martil River rehabilitation project and recently constructed dam infrastructures to reduce flood risks and to promote local socio-economic development on the ecological integrity of the river. The assessment focused on changes in fluvial landforms over time and the evaluation of aquatic ecosystems based on six physicochemical parameters (temperature, pH, electrical conductivity, dissolved oxygen, biochemical oxygen demand, and chemical oxygen demand), morpho-hydrological variables (stream width, water depth, and current speed), habitat indices (QBR, IHF, and MQI), and macroinvertebrate assemblages of EPT, OCH, and Chironomidae (Diptera) at five stations from autumn 2015 to spring 2018 (prior to and during the rehabilitation actions). The results showed that the river rehabilitation project led to profound changes in Martil River’s ecosystem and water quality over time. Physicochemical and habitat measurements at the rehabilitated sites revealed a major change in macroinvertebrate communities due to changes in fluvial landforms in relation to flow-sediment regimes. As a result, some typical species of lentic habitats disappeared, while alien, opportunistic, and lotic species appeared.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
