Package: SharkDemography 1.1.0

SharkDemography: Shark Demographic Analyses Using Leslie Matrix Models

Run Leslie Matrix models using Monte Carlo simulations for any specified shark species. This package was developed during the publication of Smart, JJ, White, WT, Baje, L, et al. (2020) "Can multi-species shark longline fisheries be managed sustainably using size limits? Theoretically, yes. Realistically, no".J Appl Ecol. 2020; 57; 1847–1860. <doi:10.1111/1365-2664.13659>.
