Sex roles and sex ratios in animals
In species with separate sexes, females and males often differ in their morphology,
physiology and behaviour. Such sex‐specific traits are functionally linked to variation in …

Sex Role Reversal and High Frequency of Social Polyandry in the Pheasant-Tailed Jacana (Hydrophasianus chirurgus)
In a few species, males invest more than females in parental care while the females invest in
mating competition and producing multiple broods for several mates. Species in the family …

[HTML][HTML] A novel function of egg burial: burying material prevents eggs rolling out of wind-swayed nests
Egg burial behaviour, that is, when parents bury the eggs with a layer of nest material during
the egg-laying stage, has been described in various egg-laying animals. Several functions …

Effects of season length and uniparental care efficacy on the evolution of parental care
Parental care patterns differ enormously among and even within species. This is exemplified
by Chinese penduline tits Remiz consobrinus, where biparental care, female‐only care …

Although biparental care is the most commonly observed pattern in bird species, the
evolutionary causations of variable parental care patterns demand more scientific attention. I …
