Life history correlations and trade-offs resulting from selection for dispersal in Tribolium castaneum

Dispersal is an important facet of the life history of many organisms and is therefore subject to selective pressure, but does not evolve in isolation. Across nature, there are examples of dispersal syndromes, life history strategies in which suites of traits coevolve, and covary with dispersal in combinations that serve to maximise fitness in a given ecological context. The red rust flour beetle, Tribolium castaneum, is a model organism and globally significant post-harvest pest that relies on dispersal to reach new patches of ephemeral habitat. Dispersal behaviour in Tribolium has a strong genetic basis. However, a robust understanding of the relationship between dispersal and other life-history components, which could elucidate evolutionary processes and allow pest managers to control their spread and reduce the impact of infestation, is currently lacking. Here we use highly replicated lines of T. castaneum previously artificially selected for divergent small-scale dispersal propensi..., , , # Life history correlations and trade-offs resulting from selection for dispersal in *Tribolium castaneum*

This repo contains data on four life-history traits evaluated in lines of *Tribolium* flour beetles artificially selected for either high or low dispersal propensity, and in some cases also unselected control lines. Those traits are male mating behaviour, female fecundity, egg-to-pupa development time, and longevity.

## Description of the data and file structure

#### Male mating behaviour (male\_mating\_behaviour\_boris.csv)

Gives the experimental line (within treatment level), selection treatment level (H=high dispersal, L=low dispersal, KSS=unselected control), replicate (within treatment; the individual video recording from which the behaviour was scored using the event logging software BORIS), experimental block, the number of 'beetle seconds' represented by each recording - the sum of the l...
