Description
Summary:This dataset includes life history parameters for 94 chondrichthyans used to calculate updated estimates of maximum intrinsic rate of population increase ( r max ) as shown in Pardo et al. (2016). The data here was primarily obtained from Garcia et al. (2008), however we have excluded species from their dataset that did not have values for maximum age or litter size. We have included life history parameters for the Basking Shark ( Cetorhinus maximus ). Life history traits included are maximum size ( length_max ), von Bertalanffy growth coefficient ( k ), age at maturity ( age_mat ), maximum age ( age_max ), average lifespan ( ave_lifespan ) which was defined as the midpoint between age at maturity and maximum age, litter size ( l ), and breeding interval ( i ). This dataset includes three different r max estimates: published estimates of r max based on the method outlined in Garcia et al. (2008) ( rmax_published_previous ), r max estimates we recalculated using the method outlined in Garcia et al. (2008) ( rmax_previous_recalc ), and updated r max estimates we calculated using the method outlined in Pardo et al. (2016) ( rmax_updated_recalc ). Given that there are slight discrepancies in r max estimates for a few species between published values from Garcia et al. (2008) and our recalculated estimates using their methodology, we used our own r max recalculation using the previous method to compare with our r max estimates based on our updated method.
