Two data files (Md_capture_H, Mn_capture_H) represent the capture histories of females of two species (Myotis daubentonii = Md, and M. nattereri=Mn). These capture histories were used to run multi-event-capture-mark-recapture model, as described in the paper, and at the end briefly here:

Modelling approach
Female’s life-cycle is captured using eight exclusive states. In each season each female occupies one of these states: 
juvenile (Juv) – a female born in the current season
pre-breeder (PB) – an adult female that is not breeding in the current season and has never bred before
failed first-time breeder (FB1) – female in her first breeding attempt, pregnant but did not give birth or offspring died soon after the birth
successful first-time breeder (SB1) - female in her first breeding attempt that has successfully weaned her offspring 
failed experienced breeder (FB2+) - female that has previously bred, pregnant in the current season, but did not give birth or offspring died soon after the birth
successful experienced breeder (SB2+) – a female that has previously bred and has successfully weaned her offspring in the current season
skipped breeder (Skip) – adult female that has bred before, but is not breeding in the current season
dead

Each female is assigned an encounter history (capture history) incorporating available information regarding her reproductive state each year. Assessments of reproductive condition were based on weight and/or visual or physical examination (to determine pregnancy), and inspection of nipple condition (nulliparous, lactating, post-lactating, or parous non-breeding). Determining the true reproductive state of a female was dependent on the timing and frequency of captures during the maternity period (e.g. some females were encountered whilst pregnant but not subsequently that season, other females were only seen in late autumn when it is no longer possible to reliably distinguish between post-lactating breeders and parous non-breeders). Thus, based on breeding phenology, we divided our reproductive assessment data into early (pregnancy), and late (post-parturition) maternity periods and defined eight events (coded 0 to 7, Table 1) that relate field observations to the true reproductive state of females in a given breeding season. The encounter history of each female consists of a series of event codes, one code per year (2007 to 2015).

The variables of the dataset are:

H: capture history of each female (see abowe for event codes)
S: number of times a capture history appears in the dataset
$COV:social_group: social group a female belongs too
$COV:first_capture_age: age of a female when captured for the first time: a=juvenile (born in the current year); b=adult (born before the current year)
