title: Data from: Limited indirect fitness benefits of male group membership in a lekking species

description: In group living species, individuals may gain the indirect fitness
 benefits characterising kin selection when groups contain close relatives.
 However, tests of kin selection have primarily focused on cooperatively
 breeding and eusocial species, whereas its importance in other forms of
 group living remains to be fully understood. Lekking is a form of grouping
 where males display on small aggregated territories, which females then
 visit to mate. As females prefer larger aggregations, territorial males
 might gain indirect fitness benefits if their presence increases the
 fitness of close relatives. Previous studies have tested specific
 predictions of kin selection models by using measures such as group-level
 relatedness. However, a full understanding of the contribution of kin
 selection in the evolution of group living requires estimating
 individuals’ indirect fitness benefits across multiple sites and years.
 Using behavioural and genetic data from the black grouse (Tetrao tetrix),
 we show that the indirect fitness benefits of group membership were
 limited because newcomers joined leks containing few close relatives who
 had limited mating success. Males’ indirect fitness benefits were higher
 in yearlings during increasing population density but overall remained
 small and only marginally changed the variation in male fitness. Kin
 selection acting through increasing group size has a limited influence on
 male fitness and is therefore unlikely to contribute substantially to the
 evolution and maintenance of lekking in this black grouse population.
