63.  Positive early-late life-history trait correlations in elephant seals.LinkIT
Oosthuizen WC, Péron G, Pradel R, Bester MN, de Bruyn PJN
EcologyEcologyPositive early-late life-history trait correlations in elephant seals.e0328810.1002/ecy.3288Correlations between early- and late-life performance are a major prediction of life-history theory. Negative early-late correlations can emerge because biological processes are optimized for early but not late life (e.g., rapid development may accelerate the onset of senescence; "developmental theory of aging") or because allocation to early-life performance comes at a cost in terms of late-life performance (as in the disposable soma theory). But variation in genetic and environmental challenges that each individual has to cope with during early life may also lead to positive early-late life-history trait correlations (the "fixed heterogeneity" or "individual quality" hypothesis). We analyzed individual life-history trajectories of 7,420 known-age female southern elephant seals (Mirounga leonina) monitored over 36 yr to determine how actuarial senescence (a proxy for late-life performance) correlate with age at first reproduction (a proxy for early-life performance). As some breeding events may not be detected in this field study, we used a custom "multievent" hierarchical model to estimate the age at first reproduction and correlate it to other life-history traits. The probability of first reproduction was 0.34 at age 3, with most females breeding for the first time at age 4, and comparatively few at older ages. Females with an early age of first reproduction outperformed delayed breeders in all aspects we considered (survival, rate of senescence, net reproductive output) but one: early breeders appeared to have an onset of actuarial senescence 1 yr earlier compared to late breeders. Genetics and environmental conditions during early life likely explain the positive correlation between early- and late-life performance. Our results provide the first evidence of actuarial senescence in female southern elephant seals.© 2021 by the Ecological Society of America.OosthuizenW ChrisWC0000-0003-2905-6297Department of Zoology

and 1.5-month-old harp seal pups were studied. Phagocytic number, proportion of phagocytic leukocytes, and phagocytic activity, average number of absorbed latex particles per leukocyte, were determined. Differences between groups of seals by average values of these indicators have not been revealed. A correlation analysis revealed a significant relationship between the phagocytic activity of leukocytes and their glycogen content in adult seals (r = 0.89). Content of cationic bactericidal protein (CP) in leukocytes of adult animals was 10-12 times higher than in pups. Correlation of CP and eosinophil count in adults was high (r = 0.88). Adult had significantly more eosinophils than pups. The noted features can provide higher efficiency of phagocytosis and destruction of absorbed bacteria in adult seals as compared to pups, despite the high level of indicators of the first, absorbing, phase of phagocytosis in the latter.KavtsevichN NNNMurmansk Marine Biological Institute, Kola Science Center, Russian Academy of Sciences, 183010, Murmansk, Russian Federation.
