AbstractAbstractThe provisioning of offspring is limited by resource abundance and is therefore likely to vary with habitat quality and the ability of parents to obtain food. Provisioning effort may also vary because males choose different life-history strategies depending on their rank and environment. Socially dominant males have higher costs of self-maintenance compared with subordinates, yet this is likely compensated for by their priority access to resources. It is unclear, however, whether this translates into benefits for females through male provisioning effort, and how this might vary with habitat suitability. We assessed patterns of body condition, blood hematocrit levels, and provisioning effort of dominant and subordinate male Black-capped Chickadees (Poecile atricapillus) breeding in two habitats known to differ in quality. Within ranks, males were similar in size and condition across habitats. Dominant males were not structurally larger than subordinates, but they were in better condition than subordinates in both habitats. There was an additive effect of habitat and dominance rank on hematocrit level; dominant males had higher hematocrit levels than subordinates regardless of habitat, and all males breeding in poor habitat had elevated hematocrits. A habitat-rank interaction revealed a greater disparity in provisioning rates among dominant and subordinate males in poor habitats. These results suggest that dominant males may be particularly good mates when resources are scarce.

Atlantic salmon have a variable life cycle. In good growing conditions, underyearling fish may metamorphose into the migratory smolt phase during their second spring, or delay at least a further year. The strategy adopted by particular fish appears to become fixed during their first summer. This paper examines whether either feeding efficiency or dominance in mid-summer correlates with the life-history strategy adopted. Eighty fish were individually marked and their feeding efficiency ( = mean handling time for food items) and dominance rank measured under laboratory conditions in mid-July. Growth rates of the fish were then monitored over the next three months, until developmental strategies became apparent. Discriminant and logistic regression analyses revealed that both dominance rank and size attained by July were independent, significant predictors of future developmental pattern (the age at metamorphosis being correctly predicted on the basis of rank and size in 84% of cases) whereas feeding efficiency had no effect. Thus fish that were dominant or larger two months after first feeding or both had a greater probability of migrating after only one year in freshwater than those more subordinate or smaller or both.

The Relationship

Life in social groups, while potentially providing social benefits, inevitably leads to conflict among group members. In many social mammals, such conflicts lead to the formation of dominance hierarchies, where high-ranking individuals consistently outcompete other group members. Given that competition is a fundamental tenet of the theory of natural selection, it is generally assumed that high-ranking individuals have higher reproductive success than lower-ranking individuals. Previous reviews have indicated large variation across populations on the potential effect of dominance rank on reproductive success in female mammals. Here, we perform a meta-analysis based on 444 effect sizes from 187 studies on 86 mammal species to investigate how life-history, ecology and sociality modulate the relationship between female dominance rank and fitness. We show that (1) dominance rank is generally positively associated with reproductive success, independent of the approach different studies have taken to answer this question; (2) life-history mechanisms mediate the relationship between rank and reproductive success, with higher effects of dominance rank on reproductive output than on survival, particularly in species with high reproductive investment; (3) the fitness benefits to high-ranking females appear consistent across ecological conditions, and (4) instead the social environment consistently mitigates rank differences on reproductive success by modulating female competition.

Behavioral Features

Abstract Life History Theory (LHT) predicts a monotonous relationship between affluence and the rate of innovations and strong correlations within a cluster of behavioral features. Although both predictions can be true in specific cases, they are incorrect in general. Therefore, the author's explanations may be right, but they do not prove LHT and cannot be generalized to other apparently similar processes.
