Ephemeroptera is an important group of insects used in the bioassessment and monitoring of freshwater bodies worldwide because of their relative abundance in a wide variety of substrates and their increasing chances of detecting pollution impacts. In this study, their faunistic composition and spatiotemporal variations in density and diversity in River Orogodo (Southern Nigeria) was investigated at five ecologically distinct stations over a 12-month period. The mayfly nymph community responses… 
Effects of physical and chemical factors on Ephemeroptera (Insecta) assemblages in an urban river of the eastern Colombian Llanos
The mayflies are insects widely known as indicators of aquatic quality in freshwater systems, they are abundant and diverse in tropical streams. In this study, it was determined the influence of
Ephemeroptera (Mayflies) Assemblages and Environmental Variation along Three Streams Located in the Dry-Hot Valleys of Baima Snow Mountain, Yunnan, Southwest China
Investigating the mayfly species assemblage and community composition along different mountain streams and identifying the environmental variation and its influence on the structure of mayfly communities within such freshwater systems found that the community composition of mayflies was different across all three watercourses.
Composition and dynamic of benthic macroinvertebrates community in semi-arid area rivers of Burkina Faso (West Africa)
The benthic macroinvertebrates communities dynamic were investigated in rivers from Burkina Faso in the purpose to analyze the taxonomic composition, the structure of benthic macroinvertebrates
Microhabitat selection and distribution of functional feeding groups of mayfly larvae (Ephemeroptera) in lotic karst habitats
Research examining mayfly ecology in karst streams and rivers has increased in recent years, though microhabitat preferences remain poorly characterized. We examined mayfly assemblage taxonomy,
Ecological status of a newly impounded sub-saharan reservoir based on benthic macroinvertebrates community (Burkina Faso, West Africa)
In West Africa, particularly in Burkina Faso, the aquatic ecosystems are under human pressures. Therefore, for long term management of these ecosystems, the managers need baseline data for regular
How well are Afrotropical mayflies known? Status of current knowledge, practical applications, and future directions
The specific and generic diversity of mayfly families from Madagascar and from 4 sub-Saharan African subregions and a concurrent comparison of this diversity with the level of taxonomic knowledge for each subregion highlights inadequacy of knowledge.
Relationships between Physico-Chemical Parameters and Taxonomic Structure of Benthic Macroinvertebrate Assemblages in Streams of West Cameroon
Tropical rivers are strongly influenced by stormwaters, pollutants and agro-pastoral activities. These systems are no longer able to maintain their native biota. Therefore, it seems important to
Impact of riparian land-use patterns on Ephemeroptera community structure in river basins of the southern Western Ghats, India
Key-words: Ephemeroptera, riparian land use, bioindicators, KMTR, Western Ghats This study analysed the impact of riparian land use in structuring the larval ephemeropteran communities from 25 sites
Effect of fish feeding on the diversity and structure of aquatic macroinvertebrates in fishponds of Blondey (Côte d’Ivoire; West Africa)
The present study was aimed to assess the effect of fish feeding on the diversity and structure of aquatic macroinvertebrates in fishponds of Blondey in Southern Côte d’Ivoire. It was conducted in


Eutrophication: are mayflies (Ephemeroptera) good bioindicators for ponds?
The trophic state of ponds appears here to be important for Ephemeroptera communities, and there is a negative relationship between total phosphorus concentrations and species richness, and Baetidae is observed as the only mayflies family present in several ponds.
Mayflies ( Insecta : Ephemeroptera ) and the assessment of ecological integrity : a methodological approach
Mayflies (Ephemeroptera) play an important role in almost all undisturbed freshwater communities and their larvae frequently form a considerable part of the material sampled during biomonitoring
Distribution and Abundance of Insect Orders in relation to Habitat types in Opa Stream-Reservoir System, Nigeria
It was inferred that Fontinalis provided strong foundations for larvae, refuge from predators, and substratum for algae and diatoms which serve as food resource for larvae in Ile-Ife, Nigeria.
Diversity and habitat preference of aquatic insects along the longitudinal gradient of the Macaé River basin, Rio de Janeiro, Brazil.
Analysis of diversity numbers indicated that all insect taxonomic orders had higher numbers on 2nd order stream reach, except for Ephemeroptera, on 4th order, however when considering morph-species taxonomic level, the higher diversity number occurred on 4 fourth order stream.
