Investigating fundamental processes in biology requires the ability to ground broad
questions in species‐specific natural history. This is particularly true in the study of behavior …

In species where both sexes care for offspring, one parent—generally the female—typically
provides more care than the other. While current theory offers broad predictions on the …

Through the effort required to construct them, the microenvironmental conditions they
impose on the family and their indirect influence on posthatching care, nests play a key role …

Resource availability should have consequences for life‐history functions and trade‐offs
among them because it influences the amounts of resources allocated to different functions …

Biparental associations are rare in most taxa. A second parent should stay with its current
brood only to enhance brood fitness or to increase its own future breeding opportunities. I …

Parental care strategies do not only vary greatly across species, but also within species
there can be substantial between‐and within‐individual variation in parental care behavior …

Although biparental care is thought to be rare among insects, it has evolved independently
numerous times resulting in diverse forms and varying levels of parental involvement …

Life-history theory predicts trade-offs between investment in current versus future
reproduction. However, many studies find no or even positive correlations among these …

Across the animal kingdom, social behaviour has been shown to be both a driver of and a
response to selection. The question of how social interactions within the family contribute to …
