In organisms in which individuals mate multiply, knowledge of the proportion of offspring sired by the last male to mate (P2) under field conditions is important for a thorough understanding of how sexual selection works in nature. In many insect groups, pronounced intraspecific variation in P2 is commonplace. Interestingly, however, in stark contrast to these observations, compilation of P2 data in dragonflies and damselflies (Odonata) indicates that a high P2, seldom below 0.95, is a feature of this taxon. Here we used double digest restriction-site associated DNA sequencing to generate a panel of single nucleotide polymorphisms (SNPs) with which we could determine paternity and estimate values of P2 in the offspring of 19 field-collected pairs of the emerald damselfly Lestes sponsa. We also estimated the relationship between P2 and male genital shape of 16 males using geometric morphometric analysis. P2 was variable (range = 0.0–1.0; mean = 0.5), and there was a marginally non-significant (P = 0.069) relationship between genital shape and P2, suggesting that males with a high P2 had an aedeagus with a broader tip. We suggest that the high P2-values reported in past studies in Odonata are partly due to the methods used to infer paternity. Use of SNPs to determine patterns of paternity and P2 in odonates is needed for a better appraisal of fitness in odonates, and would open many future avenues for use of odonates as models of sexual selection.

Implications of size‐selective fisheries on sexual selection
Uusi-Heikkilä, Silva (Wiley-Blackwell, 2020)Fisheries often combine high mortality with intensive size‐selectivity and can, thus, be expected to reduce body size and size variability in exploited populations. In many fish species, body size is a sexually selected ... -
Interspecific interactions and selection on secondary sexual characters in damselflies
Tynkkynen, Katja (University of Jyväskylä, 2005)Lajienvälinen aggressiivisuus voi selittää immenkorentokoiraiden seksuaaliominaisuuden koossa havaittavaa vaihtelua, toteaa Katja Tynkkynen väitöskirjatyössään. Sekundaarisien seksuaaliominaisuuksien, kuten koiraslintujen ... -
Size-selective harvesting fosters adaptations in mating behavior and reproductive allocation, affecting sexual selection in fish
Sbragaglia, Valerio; Gliese, Catalina; Bierbach, David; Honsey, Andrew E.; Uusi-Heikkilä, Silva; Arlinghaus, Robert (Wiley-Blackwell Publishing Ltd., 2019)The role of sexual selection in the context of harvest‐induced evolution is poorly understood. However, elevated and trait‐selective harvesting of wild populations may change sexually selected traits, which in turn can ... -
Indications of polymorphism in the behaviour and morphology of burbot (Lota lota) in a European lake
Marjomäki, Timo J.; Mustajärvi, Linda; Mänttäri, Jesse; Kiljunen, Mikko; Karjalainen, Juha (Springer, 2022)In this study, polymorphism in behaviour, morphology, and stable isotope signatures of burbot from Lake Southern Konnevesi, Finland, Europe, was examined. First, local knowledge was collected on exceptional polymorphism ... -
Sex-specific assumptions and their importance in models of sexual selection
de Vries, Charlotte; Lehtonen, Jussi (Elsevier BV, 2023)Sexual selection is a field coloured by tension and contrasting views. One contested claim is the causal link from the definition of the sexes (anisogamy) to divergent selection on the sexes. Does theory truly engage with ...
