The Evolution of Conspecific Acceptance Thresholds
- H. Reeve
- The American Naturalist
- 1 March 1989
This work attempts to provide a theory of the action component of conspecific discrimination, and examines the factors that determine the optimal or evolutionarily stable acceptance threshold, that is, the level of dissimilarity between the actor's template and the recipient's phenotype below which recipients are accepted and aboveWhich recipients are rejected.

Reproductive sharing in animal societies: reproductive incentives or incomplete control by dominant breeders?
Overall, current data on reproductive skew and its relationships to intragroup aggression and ecological constraints support the optimal skew model, but more data are needed to rule out the incomplete control model. Expand
Partitioning of reproduction in animal societies.
This work focuses on intraspecific variability in the distribution of reproduction within animal societies, and the available data suggest that this variability might be greater than previously suspected. Expand
Estimating effective paternity number in social insects and the effective number of alleles in a population
A new bias‐corrected estimator of effective number of types (mates or alleles) is derived and this new method will help researchers more accurately estimate intracolony genetic relatedness of social insects, which is an important measure in understanding their ecology and social behaviour. Expand
Conflict in single-queen hymenopteran societies : the structure of conflict and processes that reduce conflict in advanced eusocial species
This paper examines conflict over male production, queen-rearing, and sex allocation for monogynous hymenopteran societies and suggests a pluralistic rather than a typological perspective on conflict in insect societies is suggested. Expand
Signaling Individual Identity versus Quality: A Model and Case Studies with Ruffs, Queleas, and House Finches
An evolutionary model predicts that characters selected to signal individual identity will have properties differing from those expected for indicator signals of quality, which is illustrated in the ornamental, conspicuously variable, and sexually dimorphic breeding plumages of ruff sandpipers and red‐billed queleas.

Parasites, Pathogens, and Polyandry in Social Hymenoptera
Evidence of intra-nest kin-recognition mechanisms implies a long evolutionary history of discrepant reproductive interests among colony members resulting from multiple mating, in view of the potential disadvantages stemming from polyandry. Expand
Tests of reproductive-skew models in social insects.
An extension of transactional-concession models via the "workers-as-a-collective-dominant" model potentially offers new insights into some of the most striking reproductive patterns in large-colony eusocial Hymenopteran species. Expand
Adaptation and the Goals of Evolutionary Research
In this view, an adaptation is a phenotypic variant that results in the highest fitness among a specified set of variants in a given environment, and decouples adaptations from the evolutionary mechanism that generate them. Expand
