Data and analysis for 'Offspring size resolves a latitudinal population growth rate paradox in rays and skates.'

---

This repository contains the data (single phylogenetic tree from Stein et al., 2018 and batoid model data frame) and analysis for model fitting for the paper 'Offspring size resolves a latitudinal population growth rate paradox in rays and skates', published in [insert publication info]. The study investigated the scaling of offspring body mass with the maximum intrinsic rate of population increase (rmax) as well as adult body mass, temperature, and depth for 85 ray and skate species (Superorder Batoidea).

The repository contains a single script batoid-rmax-offspring-scaling.R required to fit phylogenetic generalised linear models with data available in the /data directory.

R script edited from https://github.com/EBarrowclift/batoid-rmax-scaling created for the paper Barrowclift et al.,, 2023. 'Tropical rays are intrinsically more sensitive to overfishing than the temperate skates'. https://doi.org/10.1016/j.biocon.2023.110003.
