    Environmental correlates of temporary emigration for female Weddell seals and consequences for recruitment
    (Ecological Society of America, 2014) Stauffer, Glenn E.; Rotella, Jay J.; Garrott, Robert A.; Kendall, William
    In colonial-breeding species, prebreeders often emigrate temporarily from natal reproductive colonies then subsequently return for one or more years before producing young. Variation in attendance–nonattendance patterns can have implications for subsequent recruitment. We used open robust-design multistate models and 28 years of encounter data for prebreeding female Weddell seals (Leptonychotes weddellii [Lesson]) to evaluate hypotheses about (1) the relationships of temporary emigration (TE) probabilities to environmental and population size covariates and (2) motivations for attendance and consequences of nonattendance for subsequent probability of recruitment to the breeding population. TE probabilities were density dependent (ˆerrors of population size in the previous year) and increased when the fast-ice...
