“…As aquatic insects, mayflies spend most of their developmental stages in the water. Among various environmental factors, the water temperature was shown to be crucial to the morphology, behavior, growth, and life cycle of mayflies [ 46 , 47 ]. Therefore, mayflies were proposed as appropriate models to investigate the adaptive evolution of aquatic insects in a low-temperature environment.…”

We determined 15 complete and two nearly complete mitogenomes of Heptageniidae belonging to three subfamilies (Heptageniinae, Rhithrogeninae, and Ecdyonurinae) and six genera (Afronurus, Epeorus, Leucrocuta, Maccaffertium, Stenacron, and Stenonema). Species of Rhithrogeninae and Ecdyonurinae had the same gene rearrangement of CR-I-M-Q-M-ND2, whereas a novel gene rearrangement of CR-I-M-Q-NCR-ND2 was found in Heptageniinae. Non-coding regions (NCRs) of 25–47 bp located between trnA and trnR were observed in all mayflies of Heptageniidae, which may be a synapomorphy for Heptageniidae. Both the BI and ML phylogenetic analyses supported the monophyly of Heptageniidae and its subfamilies (Heptageniinae, Rhithrogeninae, and Ecdyonurinae). The phylogenetic results combined with gene rearrangements and NCR locations confirmed the relationship of the subfamilies as (Heptageniinae + (Rhithrogeninae + Ecdyonurinae)). To assess the effects of low-temperature stress on Heptageniidae species from Ottawa, Canada, we found 27 positive selection sites in eight protein-coding genes (PCGs) using the branch-site model. The selection pressure analyses suggested that mitochondrial PCGs underwent positive selection to meet the energy requirements under low-temperature stress.

“…Although the life cycle of B. alpinus has been extensively studied over decades (e.g. Humpesch 1979;Lavandier 1988;Breitenmoser-W€ ursten & Sartori 1995;Kukula 1997;Erba et al 2003;Knispel et al 2006;L opez-Rodr ıguez et al 2008;Bottov a et al 2013), our study provides the first indication of embryonic diapause in this species.…”

“…The life cycle of B. alpinus is plastic with regard to emergence timing and voltinism (the number of generations per year, Humpesch 1979;Lavandier 1988;Breitenmoser-W€ ursten & Sartori 1995;Kukula 1997;Erba et al 2003;L opez-Rodr ıguez et al 2008;Bottov a et al 2013).

Cryptic lineages of a common alpine mayfly show strong life‐history divergence

Understanding ecological divergence of morphologically similar but genetically distinct species - previously considered as a single morphospecies - is of key importance in evolutionary ecology and conservation biology. Despite their morphological similarity, cryptic species may have evolved distinct adaptations. If such ecological divergence is unaccounted for, any predictions about their responses to environmental change and biodiversity loss may be biased. We used spatio-temporally replicated field surveys of larval cohort structure and population genetic analyses (using nuclear microsatellite markers) to test for life-history divergence between two cryptic lineages of the alpine mayfly Baetis alpinus in the Swiss Alps. We found that the more widespread and abundant cryptic lineage represents a 'generalist' with at least two cohorts per year, whereas the less abundant lineage is restricted to higher elevations and represents a 'specialist' with a single cohort per year. Importantly, our results indicate partial temporal segregation in reproductive periods between these lineages, potentially facilitating local coexistence and reproductive isolation. Taken together, our findings emphasize the need for a taxonomic revision: widespread and apparently generalist morphospecies can hide cryptic lineages with much narrower ecological niches and distribution ranges.

“…A standard way to quantify mayfly nymph length is the size frequency method, which reports probability length distributions of mayfly nymphs sampled monthly, typically reported over a year [1]. This method has been previously applied to investigate life history and development of different mayfly species adapted to a particular stream [2,5,7,8,13,14,16,29]. Although aggregation and synthesis of length distribution studies have been rare (with the exception of Clifford [6] and Huryn and Wallace [12]), monthly measurements of nymph length distribution, in conjunction with stream temperature, could help determine key parameters that affect any mathematical model of nymph population dynamics [20].…”

“…Description of mayfly life history studies analyzed.Located in the West Carpathians in Northern Slovakia (49°9'N, 19°29'E), 705 meters above sea level. For this study we analyzed length distribution data for Rhithrogena carpatoalpina.Bottová et al[2] report stream temperatures of 8°C from May to August, and 7°C from September to April. We model this annual pattern with constant decrease of 0.23°C per day between August 15 to September 15.…”
