What concept describes how larval conditions influence adult walleye size and maturity decades later?
Answer
Lengthy legacy
The influence of early life history on later fitness in walleye is encapsulated by the concept referred to as a 'lengthy legacy.' This means that specific environmental conditions encountered very early in life, such as the temperature of the spawning waters or the initial availability of prey items like zooplankton during the larval stage, can exert a persistent effect. These early cues can significantly influence later biological outcomes, including final body size, overall survival rates throughout life, and the age at which an individual reaches sexual maturity, demonstrating a strong evolutionary trade-off embedded within their biology that spans decades.
