Unexpected degrees of male courtship in a highly sexually dimorphic sex-role reversed species: raw data
<p>This repository contains the behavioural data collected from video recordings of 10 mesocosms containing *S. nigra* males and females (which were run in 2020-2021). The goals of the study are to:</p> <p>1. Describe the courtship behaviours of these sexually dimorphic fish<br> 2. Establish whether one sex is more active in courtship than the other<br> 3. Determine factors the influence sex-specific behaviours</p> <p>The data provided here are in two zipped directories: Chase_datasheets/ and BORIS_data/. Both contain data from analysis of videos in BORIS. The BORIS_data/ contains the majority of the courtship behaviours, but the videos were re-analysed to investigate chase behaviours after the courtship behaviours were scored. The chase behaviour data is in Chase_datasheets/.</p>
