Developmental density shapes adult mate guarding strategies in an invertebrate

This repository contains the data and R script associated with an experimental study examining how developmental social environment shapes post-copulatory mate-guarding behaviour in the nuptial gift–giving cricket Gryllodes sigillatus. Males and females were reared under high or low same-sex densities in a full factorial design and crossed in standardized no-choice mating trials. The dataset includes measures of mate-guarding duration, female feeding time on the spermatophylax, ampulla retention time, post-copulatory touches, and body mass for both sexes. All analyses were conducted in R, with scripts designed to run from raw data to final results without manual intervention. The manuscript of this study has been accepted for publication in Behavioral Ecology.
