Data for: Island syndrome in the critically endangered Lord Howe Island cockroach <em>Panesthia lata</em>

Following island colonisation, organisms experience a unique array of selective pressures, giving rise to a somewhat predictable suite of morphological, demographic and ecological adaptations known as the “island syndrome”. Studies of the island syndrome have provided valuable insights into processes of speciation, community assembly, adaptive radiation and ecological release, alongside many others. However, to date, behavioural aspects of island adaptation have comparatively received little scientific attention, especially among invertebrates. In this study, we examined the agonistic, courtship and aggregation behaviour of the endangered Lord Howe Island cockroach Panesthia lata, and compared these to its Australian sister species Panesthia cribrata. Behavioural assays revealed that while courtship behaviour was relatively stable across the two species, there was a significantly lower incidence of male agonism in P. lata. In concordance, analyses of nuclear single-nucleotide polymorphi..., , # Data for: Island syndrome in the critically endangered Lord Howe Island cockroach *Panesthia lata* Dataset DOI: [10.5061/dryad.fbg79cp75](https://doi.org/10.5061/dryad.fbg79cp75) ## Description of the data and file structure These data and scripts were prepared for the manuscript \"Island Syndrome in the Critically Endangered Lord Howe Island Cockroach *Panesthia lata*,\" published in *Ecology & Evolution.* ### Files and variables #### File: family_kinship_script.R **Description:** Script to analyse DArTseq SNP data and summarise kinship between individuals of *P. lata* in different aggregations. #### File: panesthia_behaviour.R **Description:** Script to analyse and visualise differences in courtship and agonistic behaviour across different populations of *P. lata* and *P. cribrata*. #### File: raw_group_size.csv **Description:** Data containing group size data for different aggregations of *Panesthia.* ##### Variables * species: *P. lata* or *P. cribrata* * population: Sou...,
