Consistent traffic noise impacts few fitness-related traits in a field cricket

Anthropogenic habitat change is occurring rapidly, and organisms can respond through within-generation responses that improve the match between their phenotype and the novel conditions they encounter. But, plastic responses can be adaptive or maladaptive and are most likely to be adaptive only when contemporary conditions reasonably mimic something experienced historically to which a response has already evolved. Noise pollution is a ubiquitous anthropogenic stressor that accompanies expanding urbanization. We tested whether the amplitude of traffic noise influences a suite of fitness-related traits (e.g. survival, life history, reproductive investment, immunity) and whether that depends on the life stage at which the noise is experienced (juvenile or adult). Our treatments mimic the conditions experienced by animals living in urban roadside environments with variable vehicle types, but continuous movement of traffic. We used the Pacific field cricket, an acoustically communicating inse..., General experimental design
We used a fully factorial design with four possible noise levels experienced during development and/or at adulthood. Each cricket had their own unique \"id.\" We assigned juvenile crickets to one of four acoustic environments: a no traffic noise treatment or one of three chronic traffic noise treatments (50dBA, 60dBA, or 70dBA) as seen in the column \"juv_treatment.\" At adulthood, we randomly reassigned the crickets to a noise treatment, as seen in the \"adult treatment\" column. The \"trial_type\" column represents the combination of the juvenile and adult treatments for each individual cricket (juvenile:adult). We then measured a suite of fitness-related traits, which we categorized as related to basic life-history (survival, development time, and adult size), reproductive investment (mating success, sperm viability, number of eggs hatched after 1 week of laying, and male and female investment in reproductive organs), and immunity (hemocyte counts and melanization..., , # Consistent traffic noise impacts few fitness-related traits in a field cricket

## Data description

The assay data are located in the file title \"20231027_F1_CompleteDataset.csv,\" and the survival data are located in the file \"20231027_F1_SurvivalDataset.csv\". The data analysis is located in the file titled \"20231027_WelshAnner_Analysis.rmd\"

Here is the summary of column names and if there are NA values:

### 20231027\_F1\_CompleteDataset.csv

* id: individual numerical ID for each cricket in the experiment
* sex: sex of experimental treatments. F=female and M=male.
* pronotum: width of the pronotum of each cricket (mm). There are NA values if the pronotum measurement wasn't recorded or there was a typo
* adult_treatment: one of 4 acoustic treatments ...
