Data from: Age-dependent trait variation: the relative contribution of within-individual change, selective appearance and disappearance in a long-lived seabird
1. Within populations, the expression of phenotypic traits typically varies with age. Such age-dependent trait variation can be caused by within-individual change (improvement, senescence, terminal effects) and/or selective (dis)appearance of certain phenotypes among older age classes. 2. In this study we applied two methods (decomposition and mixed-modelling) to attribute age-dependent variation in seven phenological and reproductive traits to within-individual change and selective (dis)appearance, in a long-lived seabird, the common tern (Sterna hirundo). 3. At the population level, all traits, except the probability to breed, improved with age (i.e., phenology advanced and reproductive output increased). Both methods identified within-individual change as the main responsible process, and within individuals, performance improved until age 6-13, before levelling off. In contrast, within individuals, breeding probability decreased to age 10, then levelled off. 4. Effects of selective appearance and disappearance were small, but showed that longer-lived individuals had a higher breeding probability and bred earlier, and that younger recruits performed better throughout life than older recruits in terms of both phenology and reproductive performance. In the year prior to death, individuals advanced reproduction, suggesting terminal investment. 5. The decomposition method attributed more age-dependent trait variation to selective disappearance than the mixed-modelling method: 14-36% versus 0-8%, respectively, which we identify to be due to covariance between rates of within-individual change and selective (dis)appearance leading to biased results from the decomposition method. 6. We conclude that the decomposition method is ideal for visualising processes underlying population change in performance from one age class to the next, but that a mixed-modelling method is required to investigate the significance and relative contribution of age-effects. 7. Considerable variation in the contribution of the different age-processes between the seven phenotypic traits studied, as well as notable differences between species in patterns of age-dependent trait expression, calls for better predictions regarding optimal allocation strategies with age.
Data from: We happy few: using structured population models to identify the decisive events in the lives of exceptional individuals
In any population, some individuals make it big: they are among the few that produce many offspring, grow to large size, and so on. What distinguishes the lives of these happy few? We present three approaches for identifying what factors distinguish those "lucky" individuals who come to dominate reproduction in a population without fixed differences between individuals (genotype, site quality, etc.): comparing life-history trajectories for lucky and unlucky individuals and calculating the elasticity of the probability of becoming lucky to perturbations in demographic rates at a given size or a given age. As examples we consider published size-structured integral projection models for the tropical tree Dacrydium elatum and the semiarid shrub Artemisia ordosica and an age-size-structured matrix model for the tropical tree Cedrela ordosica. We find that good fortune (e.g., rapid growth) when small and young matters much more than good fortune when older and larger. Becoming lucky is primarily a matter of surviving while others die. For species with more variable growth (such as Cedrela and Ordosica), it is also a matter of growing fast. We focus on reproductive skew, but our methods are broadly applicable and can be used to investigate how individuals come to be exceptional in any aspect.
Data from: Is telomere length a molecular marker of individual quality? insights from a long-lived bird
1. In wild vertebrates, some individuals survive and reproduce better than others and this has led to the concept of individual quality. Despite its importance when studying ecological processes and life-history trade-offs, measuring individual quality is complex because individuals must be followed during a large part of their life. 2. Recently, telomere biology has been successfully brought into ecology and telomere length has been suggested to be a promising molecular tool to evaluate individual quality in wild vertebrates ('the telomere – individual quality hypothesis'). 3. In this study, we tested this hypothesis in a long-lived species, the Black-browed albatross (Thalassarche melanophrys) by simultaneously measuring telomere length and several potential complementary phenotypic proxies of individual quality in a single year. In addition, we followed the return rate and the reproductive performance of these same albatrosses for a decade. 4. We found that long telomeres were associated with several markers of high individual quality (foraging behaviour, body size, and stress hormone levels). Furthermore, we found that a single measure of telomere length could predict future offspring productivity, for at least several years following telomere measurement (better productivity being associated with longer telomeres). 5. Altogether, these results support the 'telomere – individual quality hypothesis' and suggest that telomere length can be useful to estimate individual quality in long-lived seabirds.
