“…Herrmann & Andersson (1986) have shown an increased respiration rate in mayfly nymphs exposed to 0.5 mg 1-i aluminium at pH 4.0 and pH 4.8 and attribute this to (1) decreased oxygen transport because of impaired osmoregulation and ion transport, and (2) aluminium hydroxide precipitation and mucus production on the gill plates. However, the results of the present study and the observation that Baetis nymphs can survive without gill plates (Wingfield, 1939), suggests that the gill plates are not the sole target organ but that aluminium physically occludes the main respiratory surface, the integument, leading to an increased respiration rate and subsequent death. Stoner et al (1984) in a field study of the same catchment used in this investigation found gill aluminium concentrations of caged 0+ brown trout in the range 673 -3 505 pg g-i dry wt.…”

Salmonids (Salmo salar, Salmo trutta) and mayflies (Baetis rhodani, Ecdyonurus venosus) which had been exposed to simulated episodes of low pH, and low pH with elevated aluminium, were examined histochemitally for the presence of aluminium and mucus. The control fish and mayflies and those exposed to low pH did not stain for aluminium, although increased mucus production was demonstrated in fish gills. Trout and salmon exposed to aluminium at low pH exhibited extensive aluminium and mucus coating of the secondary gill lamellae. No mucus was produced by mayflies but aluminium was apparent on all parts of the body. Mean aluminium concentrations of digested fish gills were 2950 and 3050 pg g-' dry wt. for trout and salmon respectively, whilst for whole specimens of B. rhodani and E. venosus values were 1200 and 3 175 pg g-' dry wt.

“…Remarkably, OBP-expressing cell clusters were HRP-positive, suggesting a neurosensory nature. Globally, these results strongly suggest that, beyond their respiratory role 31 , the gills are a major chemosensory organ of the aquatic mayfly nymph (Figure 2f-g).…”

The first winged insects underwent profound morphological and functional transformations leading to the most successful animal radiations in the history of earth. Despite this, we still have a very incomplete picture of the changes in their genomes that underlay this radiation. Mayflies (Ephemeroptera) are one of the extant sister groups of all other winged insects and therefore are at a key phylogenetic position to understand this radiation. Here, we describe the genome of the cosmopolitan mayfly Cloeon dipterum and study its expression along development and in specific organs. We discover an expansion of odorant-binding proteins, some expressed specifically in the breathing gills of aquatic nymphs, suggesting a novel sensory role for gills. In contrast, as flying adults, mayflies make use of an enlarged set of opsins and utilise these visual genes in a sexually dimorphic manner, with some opsins expressed only in males. Finally, to illuminate the origin of wings, we identify a core set of deeply conserved wing-specific genes at the root of the pterygote insects. Globally, this is the first comprehensive study of the structure and expression of the genome of a paleopteran insect and shows how its genome has kept a record of its functional adaptations.

“…Dewitz, already in 1890, described that mayfly nymphs were able to regenerate their gills completely after amputation [93]. Since then, several researchers [94, 95] confirmed these observations. Indeed, we observed that C. dipterum is able to regenerate gills, antennae, cerci and legs completely in a very short period of time, ranging from six to nine days (Fig.…”

Establishment of the mayfly Cloeon dipterum as a new model system to investigate insect evolution

The great capability of insects to adapt to new environments promoted their extraordinary diversification, resulting in the group of Metazoa with the largest number of species distributed worldwide. To understand this enormous diversity, it is essential to investigate lineages that would allow the reconstruction of the early events in the evolution of insects. However, research on insect ecology, physiology, development and evolution has mostly focused on few well-established model species. The key phylogenetic position of mayflies within Paleoptera, as the sister group of the rest of winged insects and life history traits of mayflies make them an essential order to understand insect evolution. Here, we describe the established of a continuous culture system of the mayfly Cloeon dipterum and a series of experimental protocols and -omics resources that allow the study of its development and its great regenerative capability. Thus, the establishment of Cloeon as an experimental platform paves the way to understand genomic and morphogenetic events that occurred at the origin of winged insects.
