Molecular systematics and phylogeography of the cryptic species complex Baetis rhodani (Ephemeroptera, Baetidae).
Genetic studies have highlighted cryptic diversity in many well-known taxa including aquatic insects, with the general implication that there are more species than are currently recognised. Baetis rhodani Pictet are among the most widespread, abundant and ecologically important of all European mayflies (Ephemeroptera), and used widely as biological indicators of stream quality. Traditional taxo...
متن کاملBaetis (Baetis) cypronyx sp. n., a new species of the Baetis alpinus species-group (Insecta, Ephemeroptera, Baetidae) from Cyprus, with annotated checklist of Baetidae in the Mediterranean islands
A detailed description of the larvae of Baetis (Baetis) cypronyx sp. n., a representative of the Baetis alpinus species-group within the mayfly family Baetidae, is provided, including a differential diagnosis with regard to closely related species of the group, especially Baetis melanonyx (Pictet, 1843) and Baetis baroukianus Thomas & Dia, 1984. The new species is mainly distinguished by mouthp...
متن کاملMtDNA COI barcodes reveal cryptic diversity in the Baetis vernus group (Ephemeroptera, Baetidae).
Partial mitochondrial COI sequences (barcoding fragment) were explored for the understanding of the species boundaries of Baetis vernus group taxa (Ephemeroptera, Baetidae) in northern Europe. We sampled all species of this group occurring in Finland, but focused on taxa for which morphological and taxonomical confusion have been most apparent. The sequence matrix comprised 627 nucleotides for ...
متن کاملCroatian mayflies (Insecta, Ephemeroptera): species diversity and distribution patterns
Knowledge of the mayfly biodiversity in the Balkan Peninsula is still far from complete. Compared to the neighbouring countries, the mayfly fauna in Croatia is very poorly known. Situated at the crossroads of central and Mediterranean Europe and the Balkan Peninsula, Croatia is divided into two ecoregions: Dinaric western Balkan and Pannonian lowland. Mayflies were sampled between 2003 and 2013...
متن کاملEffects of subacute doses of cadmium on pH-stressed Leptophlebia marginata (L.) and Baetis rhodani Pictet (Insecta: Ephemeroptera).
Cd uptake, emergence, survival and locomotory activity at two pH levels were studied in a 27-day experiment with Leptophlebia marginata and in a 19-day experiment with Baetis rhodani. Model ecosystems containing recirculating stream water, patches of sediment and leaves, simulated a natural stream. During the experiments, concentrations of Al, Cd, Fe and Zn increased in the water at pH 5, while...
