OVOVIVIPARITY AND NYMPHAL SEASONAL MOVEMENTS OF CALLIBAETIS SPP. (EPHEMEROPTERA: BAETIDAE) IN A POND IN SOUTHWESTERN QUEBEC

Can. Ent. 111: 927-931 (1979) Callibaetis ferrugineus (Walsh) and C . Jluctuans (Walsh) nymphs moved from the shallow, peripheral area of a pond during the late summer and autumn to the deeper water where they overwintered. In the spring they returned to the peripheral area where they were found throughout the summer. C . ferrngineus and C . jluctuans are ovoviviparous. A relationship between ovoviviparity and seasonal movements of the nymphs is suggested.

“…Gene expression dynamics reflect life cycle adaptations. C. dipterum spends its life cycle in three different environments: within the abdomen of the mother during embryonic stages (as C. dipterum is one of the few ovoviviparous mayfly species 16 ); freshwater streams and ponds as nymphs; and land/air as adults 17 . To explore gene expression patterns during these three major phases, we performed a temporal soft-clustering analysis of stage-specific transcriptomes using Mfuzz 18 and focused on clusters containing genes whose expression peaks at each of these phases ( Fig.…”

Genomic adaptations to aquatic and aerial life in mayflies and the origin of insect wings

The evolution of winged insects revolutionized terrestrial ecosystems and led to the largest animal radiation on Earth. However, we still have an incomplete picture of the genomic changes that underlay this diversification. Mayflies, as one of the sister groups of all other winged insects, are key to understanding this radiation. Here, we describe the genome of the mayfly Cloeon dipterum and its gene expression throughout its aquatic and aerial life cycle and specific organs. We discover an expansion of odorant-binding-protein genes, some expressed specifically in breathing gills of aquatic nymphs, suggesting a novel sensory role for this organ. In contrast, flying adults use an enlarged opsin set in a sexually dimorphic manner, with some expressed only in males. Finally, we identify a set of wing-associated genes deeply conserved in the pterygote insects and find transcriptomic similarities between gills and wings, suggesting a common genetic program. Globally, this comprehensive genomic and transcriptomic study uncovers the genetic basis of key evolutionary adaptations in mayflies and winged insects.

“…Cloeon dipterum , from the Baetidae family, is one of the few ovoviviparous ephemeropteran species: the female keeps the fertilised eggs inside the abdomen and only when they are ready to hatch, after 10–20 days, the female sets down onto the surface of a water stream or pond and lays the eggs that sink to the bottom ready to eclode. Just few seconds after the eggs are laid, the nymphs hatch [58].…”

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 establishment 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.
