Fluctuating salinity during development impacts fish life histories.

ABSTRACT: Climate change and human activities are elevating the level and variability of salinity in freshwater ecosystems. Consequently, many aquatic species now experience more extreme developmental environments. Resultant shifts in developmental trajectories could change key life-history traits that persist into adulthood. The 'silver spoon' hypothesis posits that favourable developmental conditions lead to faster growth, earlier maturation and greater reproductive success. In contrast, the 'predictable adaptive response' hypothesis suggests that faster growth and earlier reproduction should be selected for under stressful developmental conditions because stress provides cues about a higher risk of mortality in future environments. To understand life-history responses to salinity during developme
