Title Individual-level survival data for Serengeti and Hwange lions
Downloaded 47 times
Description The structure of the data in datSH.txt by columns is as follows: 1) "id" = individual identifier: sequence from 1 to 4754; 2) "sex" = sex of indvidual: male, female, unknown (m/f/u); 3) "dead" = binary indicator of whether death was confirmed at dissapearance: surely dead? (yes/no); 4) "cens" = censored observation: individual still alive at end of study? (yes/no); 5) "xli" = last seen age of individual i in years; 6) "xti" = left-truncation age of individual i (i.e. “first seen”) in years; 7) "loc" = location: observation from Serengeti or Hwange (s/h); 8) "potEm" = potential emigrant: characteristics of individual at last seen age indicate that the indivdiual may have dispersed (yes/no); 9) "im" = immigrant: individual immigrated into the study area (yes/no); 10) "unsex" = unsexed: did the indvidual die before sex was determined? (yes/no); 11) "outMigr" = out-migrant: expert opinion on whether individual may have dispersed (yes/no), only relevant for Serengeti data. Note that for the binary indicators 1 indicates "yes", 0 indicates "no". Data are based on mark-resighting records of the Hwange and Serengeti lion population, respectively. For details on the data collection protocol, please see the "Materials and methods" section in the associated paper. Further questions can be addressed to Andrew Loveridge (andrew.loveridge@zoo.ox.ac.uk) for the Hwange data and to Craig Packer (packer@umn.edu) for the Serengeti data.

Title R code to fit the mortality model
Downloaded 50 times
Description R code to fit the Siler mortality model to re-sighting data of male and female lions from two populations (i.e. Hwange National Park and Serengeti National Park, respectively). For running the analysis that is presented in the associated paper, download this file "runsModel.R" and the corresponding functions file "fcts01.R". Furthermore, please download the data file "datSH.txt". Save all files to the same folder. Set your R working directory to that folder using the corresponding line in "runsModel.R". Run the model by running "runsModel.R". When the model is finished, the model output will be automatically stored as an Rdata file to the working directory folder. There will be three output objects, which store the output pertaining to the three model start ages. The three output objects will be a composite name of the nature: outFrom"model start age"_"version".Rdata (e.g. outFrom1_01.Rdata for start age x = 1 and model version 01). Please see the documentation/comments in the code for further details on the starting objects, model fitting process, and the output objects.
