“…The presence of the S. ornatum group has been recorded in several studies for localities across Algeria, namely the Batna Department and Bouïra Province (Edwards 1923), Biskra Province (Belazzoug & Tabet-Derraz 1980), the Oued El Haï Basin (Arigue et al 2016), the Djurdjura Mountains (Lounaci et al 2000b), the Tlemcen Mountains (Gagneur & Clergue-Gazeau 1988;Boudghane-Bendiouis et al 2014), the Seybouse Basin (Cherairia et al 2014), and El Kala, north-eastern Algeria (Samraoui et al 2021).…”

Besides their important ecological role in flowing waters, blackflies (Diptera: Simuliidae) may pose medical and veterinary risks. For seventeen months, we surveyed the blackflies of ten localities across the Aures Mountains, in the Saharan Atlas, Algeria, and recorded eight taxa (i.e. species, species groups or species complexes). High altitude sites were dominated by the Simulium ornatum (Meigen, 1818) group, whereas sites located on the southern slope of the Aures Mountains were occupied by the eurytopic Simulium velutinum (Santos Abreu, 1922) complex and the thermophilic, pollutant-tolerant Simulium ruficorne Macquart, 1838 ‘A’ morphotype.Co-inertia analysis was used to determine the relationship between a species’ abundance and habitat types. The co-inertia analysis revealed a likely co-structure between blackfly assemblages and measured environmental descriptors (water temperature, conductivity, current velocity, bed width, etc.) in sampled habitats. This confirmed the importance of altitude as a driver of blackfly distribution. Our results also showed that there has been an increase in anthropogenic pressures on the vulnerable freshwater biota of the Aures Mountains.

“…Previous research has highlighted how the abundance and distribution of the larvae and pupae of a few key blackfly species-usually of medical importance-may be affected by specific environmental factors (Jitklang et al, 2020) such as substrate type (Roberts, 1986), water flow velocity (Rivers-Moore et al, 2007), elevation (Low et al, 2014;Mantilla et al, 2018) or temperature (Rivers-Moore & Palmer, 2018). Attention has been paid to simuliid assemblages (McCreadie & Adler, 2012;Ya'cob et al, 2016;Cheke et al, 2017;Cuadrado Argel et al, 2019;Samraoui et al, 2021) and the extent of species replacement along environmental gradients (Shields et al, 2006), which can be of importance for the geographical distribution of blackfly pest species. Additionally, as the females of the haematophagous blackfly species lay their eggs after digesting a blood meal, breeding habitats may be correlated with landscape variables affecting female feeding chances (e.g.…”

Geographical distribution and abundance of the pupae of six blackfly species of medical and veterinary concern were studied in eastern Spain according to three different sets of explanatory variables including in-stream variables, both (i) abiotic (i.e., physicochemical) and (ii) biotic (i.e., richness and abundance of either taxonomically or ecologically close related taxa), as well as (iii) meteorological and landscape variables. The results showed specific habitat requirements for pupation in Simulium (Boophthora) erythrocephalum (De Geer, 1776) and Simulium (Wilhelmia) equinum (Linnaeus, 1758), two of the six species studied regarding elevation and temperature. While the rest of the species showed a certain degree of ecological overlap, co-occurrence was in general low, which suggested that antagonistic biotic factors may be important in structuring blackfly assemblages. In effect, biotic predictors explained a high proportion (50%-70%) of the variability in the abundance of the pupae of the most generalist blackfly species, although further studies are needed to disentangle the sign of interspecific interactions. At the landscape level, S. (W.) equinum and S. (W.) pseudequinum Séguy, 1921 breeding habitats were associated with the presence of pig farms, and S. (Simulium) reptans (Linnaeus, 1758) and S. (B.) erythrocephalum with the presence of cattle.

Despite its biogeographical importance and high endemism, the freshwater biodiversity in Algeria and the wider arid region of North Africa has been significantly under‐researched and underestimated. Mayflies (Ephemeroptera) are crucial for the maintenance of ecological integrity of hydrosystems and could serve as indicators of changes of North African freshwater biodiversity. This study focuses on mayflies in Algeria, particularly in the Djurdjura Mountains, including the Djurdjura National Park in central‐northern Algeria. The aim is to establish an updated checklist, map the distribution of mayfly species and determine the ecological requirements of their assemblages. Twenty‐four mayfly taxa were identified during the study, including five new, undescribed species. Through multivariate analysis, the study revealed that land‐use practices, altitude and slope orientation significantly influenced mayfly assemblages in the studied streams. This study emphasises the urgent need for conservation action and lays the foundation for future research and conservation efforts that are essential to protecting the integrity of the critical freshwater habitats of the Djurdjura Mountains, which are hotspots for North African endemic species.
