Abstract
Behavioral flexibility could help animals cope with costs of genetic variants under selection, promoting unexpected genetic adaptation. To test this, we investigated how a critical acoustic communication signal – song – was rapidly lost due to genetic mutation in crickets exposed to lethal, eavesdropping parasitoids. We first determined that offspring production was equivalent in replicate silent versus singing populations using a controlled, naturalistic arena. Using our custom engineered high-resolution individual-based tracking system for low-light conditions, we found that fitness compensation in silent conditions was associated with increased locomotion in both sexes. Our results provide direct evidence that flexible behavior can promote genetic adaptation via compensation in reproductive output. The rapid evolution of animal communication systems may be less constrained than previously appreciated.

Tracking output_main: These data result from the tracking of multiple crickets during a three hour period. Cricket locations were extracted from a series of images, movement metrics were calculated in MATLAB and collated in this file. The statistical analysis was then performed in R using this dataset.
Hawaii demographics: These data were collected on Hawaiian islands in order to determine the cricket density and demographics to use in the tracking experiment. Grids were placed in field locations and crickets were counted. Full methods in published article.
trial_corrected.mat: This is the raw X/Y movement data, as output by the tracking system.
exportDataToSpreadsheet.m This MATLAB script is used to obtain the movement metrics ('tracking output_main.xlsx') from the raw movement data.
Description of the data and file structure
Tracking output_main: Distance is given in pixels moved. Convert to meters by dividing by 4000. Time is always given in minutes. Weight is given in milligrams. OtherSexPropVar is the proportional variation in time spent near (within 10 cm) crickets of the opposite sex. Age is given in days.
Hawaii demographics: [Sheet 1] Information on each grid placement. Not all measurements could be taken for each GRID, and so some values are missing. Temperature is given in deg C. Start and Stop are the times of searching starting and ending. LUX is the unit of illuminance taken at the start of each search. [Sheet 2] Locations of crickets found in each grid. X and Y coord given in centimeters within each. Type M is male (only for nymphs), F female, FW is flatwing male, N is normal male. Pop relates to locations in sheet 1. In grids where no crickets were found, a placeholder grid ID is provided but with empty fields.
