Behavioural plasticity allows organisms to respond to environmental challenges on short
time scales. But what are the ecological and evolutionary processes that underlie …

The social environment can affect the development of behavioural phenotypes in fish, and it
is important to understand such effects when rearing fish in artificial environments. Here, the …

Cognitive and sensory abilities are vital in affecting survival under predation risk, leading to
selection on brain anatomy. However, how exactly predation and brain evolution are linked …

Elevated levels of ambient predation risk have been shown to elicit changes in behaviour,
physiology, morphology, and cognitive function of prey animals. While there is a growing …

Pacific salmon (Oncorhynchus spp.) hatch and feed in freshwater habitats, migrate to sea to
mature, and return to spawn at natal sites. The final, riverine stages of the return migrations …

Teleost fish are neuroplastic and are known to alter their brain morphology and behaviour in
response to environmental change such as an increase in predation pressure. The …

Behavioural plasticity plays an important role in an organism's ability to adapt to captive
settings, but a lack of perceived predation risk during early development in captivity can lead …

Neuroplasticity enables teleosts to promote or downregulate the growth of their brains
regionally. To compensate for the effects of predation pressure, teleosts may alter their brain …

Survivorship under predation exerts strong selection on reproductive traits as well as on
brain anatomy of prey. However, how exactly predation and brain evolution are linked has …

Teleosts exhibit extensive, ongoing neuroproliferation within their brains even as adults,
which facilitates indeterminate growth and permits them to recover from injuries to their …
