Individuals are expected to avoid mating with relatives as inbreeding can reduce offspring
fitness, a phenomenon known as inbreeding depression. This has led to the widespread …

Social life and lifelong partner commitments are expected to favor thorough partner choice,
as an ill-suited partnership may have long-term consequences, adversely affecting the …

Sex allocation is one of the most studied traits in evolutionary biology because its theoretical
predictions match the empirical data. Here, using the Ryukyu dry-wood termite Neotermes …

Sexually reproducing organisms face a strong selective pressure to find a mate and ensure
reproduction. An important criterion during mate‐selection is to avoid closely related …

Single-piece nesting termites live and forage in the same piece of wood throughout their life,
which limit their colony size. In certain species, more than one colony thrive in a given piece …

Inbreeding costs can be high in haplodiploid hymenopterans due to their particular
mechanism of sex determination (ie, single-locus complementary sex-determination system …

Sib‐mating avoidance is a pervasive behaviour that is expected to evolve in species subject
to inbreeding depression. Although laboratory studies provide elegant demonstrations …

Investment in soldier production in eusocial lineages involves a trade‐off between
maintenance costs and defense benefits. Termites are eusocial insects that live in colonies …

Many animals have evolved strategies to reduce risks of inbreeding and its deleterious
effects on the progeny. In social arthropods, such as the eusocial ants and bees, inbreeding …

In social insects, individuals of working caste coordinate their actions to manage various
collective tasks. Such collective behaviours exist not only in workers but also in winged …
