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 …

Despite rising interest among scientists for over two centuries, parental care behavior has
not been as thoroughly studied in amphibians as it has in other taxa. The first reports of …

Highlights•Eusociality evolved multiple times in insects, either via the brood care or the nest
defense route.•There are several confounding factors in molecular studies of brood care or …

Juvenile hormone (JH) is a modulator of many physiological transitions in insects, including
molting, metamorphosis, diapause, and reproduction. These processes often include …

Parental care has evolved convergently an extraordinary number of times among tetrapods
that reproduce terrestrially, suggesting strong positive selection for this behavior in the …

A key component of parental care is avoiding killing and eating one's own offspring. Many
organisms commit infanticide but switch to parental care when their own offspring are …

Background Consistent individual differences in behaviour, known as animal personalities,
have been demonstrated within and across species. In fish, studies applying an animal …

Behaviour is often a front line response to changing environments. Recent studies show
behavioural changes are associated with changes of gene expression; however, these …

Parental care is thought to evolve through modification of behavioral precursors, which
predicts that mechanistic changes occur in the genes underlying those traits. The duplicated …

Highlights•JH has both gonadotropic and non-gonadotropic roles in eusocial insects.•It is
not known whether this represents a novel role or multiple conserved roles.•Study of non …
