Dataset: Long-term changes in survival of Eurasian lynx in three reintroduced populations in Switzerland

For conservation or management programs, basic data on vital rates are important but often hard to acquire for long-lived and elusive wildlife species such as large carnivores. In this study, we analysed long-term changes in survival rates for different sexes and age classes (juvenile, subadult, adult) in three reintroduced Swiss lynx populations (Alps, Jura, Northeastern Switzerland). A novel modelling approach allowed us to combine picture data from camera-trapping and lynx pictures resulting from chance observations, telemetry data and dead-recoveries over a monitoring period of 25 years (1997–2022). Mean annual survival of adult lynx varied between 0.71 and 0.81 for males and between 0.70 and 0.85 for females. Mean survival of subadults ranged between 0.59 and 0.89 among populations. Juvenile survival was highly variable and low on average (< 0.4). Our findings highlight that unknown sources of mortality exist in some populations and that future studies on mortality causes and po..., see html files provided with the data, , # Dataset: Long-term changes in survival of Eurasian lynx in three reintroduced populations in Switzerland

## Description of the data and file structure

This data was created for analyses of the long-term development of survival rates for different sexes and age classes in three reintroduced Swiss lynx populations (Alps, Jura, Northeastern Switzerland (NECH)).

We upload a folder for each population (ALPS, JURA, NECH) which contains subfolders for data and jags code and a html file titled 'Supplementary materials & README_' which contains further information on data preparation, variable names, R code, model estimates and supplementary information for the related article. The data file 'datax_' contains capture histories in 2-month occasions based on picture data from camera-trapping and chance observations, telemetry data and dead-recoveries over a monitoring period of 25 years (1997–2022). The data f...
