Conditions fish encounter during embryogenesis and early life history can leave lasting
effects not only on morphology, but also on growth rate, life‐history and behavioural traits …

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 …

There is growing evidence that maternal experience influences offspring via non-genetic
mechanisms. When female three-spined sticklebacks (Gasterosteus aculeatus) were …

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

How can the stunning diversity of social systems and behaviours seen in nature be
explained? Drawing on social evolution theory, experimental evidence and studies …

Social animals can greatly benefit from well-developed social skills. Because the frequency
and diversity of social interactions often increase with the size of social groups, the benefits …

Despite a vast literature on the factors controlling adult size, few studies have investigated
how maternal size affects offspring size independent of direct genetic effects, thereby …

Out-group conflict is rife in the natural world, occurring from primates to ants. Traditionally,
research on this aspect of sociality has focused on the interactions between groups and their …

Alloparental brood care, where individuals help raising the offspring of others, is generally
believed to be favoured by high degrees of relatedness between helpers and recipients …

The environment that an offspring experiences during its development can have lifelong
consequences for its morphology, anatomy, physiology and behaviour that are strong …
