Parents affect offspring fitness by propagule size and quality, selection of oviposition site,
quality of incubation, feeding of dependent young, and their defence against predators and …

The consequences of polyandry for female fitness are controversial. Sexual conflict studies
and a meta‐analysis of mating rates in insects suggest that there is a longevity cost when …

Predator effects on prey demography have traditionally been ascribed solely to direct killing
in studies of population ecology and wildlife management. Predators also affect the prey's …

Humans stand out among the apes by having both an extremely large brain and a relatively
high reproductive output, which has been proposed to be a consequence of cooperative …

How do parents recognize their offspring when the cost of making a recognition error is high
[1–3]? Avian brood parasite-host systems have been used to address this question because …

Central questions of behavioural and evolutionary ecology are what factors influence the
reproductive success of dominant breeders and subordinate nonbreeders within animal …

The conundrum of why subordinate individuals assist dominants at the expense of their own
direct reproduction has received much theoretical and empirical attention over the last 50 …

Life-history theory predicts that individuals should adjust their reproductive effort according
to the expected fitness returns on investment. Because sexually selected male traits should …

Hel** by group members is predicted to lead to delayed senescence by affecting the trade-
off between current reproduction and future survival for dominant breeders. Here we …
