Data for: Surviving the serenade: how conflicting selection pressures shape the early stages of sexual signal diversification

Understanding how the early stages of sexual signal diversification proceed is critically important because these microevolutionary dynamics directly shape species trajectories and impact macroevolutionary patterns. Unfortunately, studying this is challenging because signals involve complex interactions between behavior, morphology, and physiology, much of which can only be measured in real time. In Hawaii, male Pacific field cricket song attracts both females and a deadly parasitoid fly. Over the past two decades, there has been a marked increase in signal variation in Hawaiian populations of these crickets, including novel male morphs with distinct mating songs. We capitalize on this rare opportunity to track changes in morph composition over time in a population with three novel morphs, investigating how mate and parasitoid attraction (components of sexual and natural selection) may shape signal evolution. We find dramatic fluctuation in morph proportions over the three years of the ..., , , # README for data files accompanying Gallagher et al.

## Data File #1: song\_analysis.csv

---

A data frame with calling song data from field-collected male Teleogryllus oceanicus crickets of different morphs. Data include unique male ID, morph, and two analyzed song characteristics.

### Description of the data and file structure

---

Descriptions of column names:
male_ID: unique male identifier.
morph: discrete male morph.
dominant_frequency: frequency (in Hz) with the greatest acoustic power.
amplitude: amplitude ratio (relative to background noise).

## Data File #2: morph\_proportions\_over\_time.csv

---

A data frame with male morph proportion data from field-sampled Teleogryllus oceanicus crickets from the first and last points of the study: 1 and 5. Compared using a Fisher's exact test.
