Data from: Sperm competition and the evolution of precopulatory weapons: Increasing male density promotes sperm competition and reduces selection on arm strength in a chorusing frog

Sexual dimorphism data for Crinia georgianaThe snout-vent length (mm), and arm girth (mm) of males and females of the Australian quacking frog Crinia georgiana, for an analysis of sexual dimorphism in arm girth.Sexual dimorphism.csvCalling, mating and polyandry probabilitiesData for the analyses of mating tactics, mating success and polyandry probability in the Australian quacking frog Crinia georgiana. The columns mean: Study site (BS = Burt Street in Albany, WA; WB = William Bay; HF = swamp near the Hockey Field in Albany, WA; KG = Kangaroo Gully), quadrat ID, snout-vent length (mm), arm girth (mm), male density, mating tactic (calling or silent), mating success (0 or 1), whether a mating was polyandrous (0 or 1), the number of males per mating, and extra notes.Number of males per matingData for the analysis of number of males involved in matings of the Australian quacking frog Crinia georgiana. The columns mean: Study site (MS = Melville Street in Albany, WA; BS = Burt Street in Albany, WA; WB = William Bay; HF = swamp near the Hockey Field in Albany, WA; KG = Kangaroo Gully), quadrat ID, number of males involved in the mating, and male density.
