In this article Fig. 2D is incorrectly appeared some labels are missing and labels on the Y-scale are displaced. The figure should have appeared as shown below.

Estimation of operational sex ratio in polyandrous and monoandrous mating regimes. A B Seasonal changes in the percentage of non-virgin females (A) and males (B) are shown with extracted data points (dashed red boxes) for approximate linearization (insets). The data collected in 2019–2022 were combined in the same plots. C Schematic diagram showing transitions of female status under polyandrous and monoandrous mating regimes. In polyandrous mating regime, females gain their receptivity to mate at a certain growth point where female status changes irreversibly from “not being ready to mate” (open box) to “being ready to mate” (grey box). In monoandrous mating regime, females reverse their status from “being ready to mate” (grey box) to “not being ready to mate” (open box) when they mate once (broken orange line with arrow). D, Daily changes in OSR calculated using the method in accordance with either polyandrous (purple plots) or monoandrous (green plots) mating regimes. The inset represents the semilogarithmic scale
