Long-lived animals with a low annual reproductive output need a long time to recover from population crashes and are, thus, likely to face high extinction risk, if the current global environmental change will increase mortality rates. To aid conservation of those species, knowledge on the variability of mortality rates is essential. Unfortunately, however, individual-based multi-year data sets that are required for that have only rarely been collected for free-ranging long-lived mammals. Here, we used a five-year data set comprising activity data of 1445 RFID-tagged individuals of two long-lived temperate zone bat species, Natterer’s bats (Myotis nattereri) and Daubenton’s bats (Myotis daubentonii), at their joint hibernaculum. Both species are listed as being of high conservation interest by the European Habitats Directive. Applying mixed-effects logistic regression, we explored seasonal survival differences in these two species which differ in foraging strategy and phenology. In both species, survival over ... : SeasonalSurvivalBats_DataSetThe file contains data on seasonal survival in bats collected at a hibernaculum in the field. The csv file has been created with the software R. It shows information about the according hibernation period (batyear; August - April of the five study years 2010/2011 - 2014/2015); the specific part of the hibernation period in detail (time_period), the season (season; winter, summer), the bat species (species; mn - Myotis nattereri, md - Myotis daubentonii), individual bats (bat_id), the sex of the individual (sex; f - female, m - male), the assigned age class of the individual (age_class; ad - adult, juv - juvenile), the presence within the specific time period (presence; 1 - has been present, 0 - has not been recorded at the hibernaculum although it has been alive) and status of survival (surv; 1 - survived, 0 - assigned dead).
