The impacts of climate change on marine organisms will depend on their ability to tolerate, acclimate and eventually adapt to the environmental change. We performed unique transgenerational experiments to determine the molecular response of a coral reef fish to ocean acidification. Our complex design allows us to: 1) investigate the importance of parental exposure to ocean acidification...

For a number of years we have been using a coral reef damselfish, Acanthochomis polyacanthus, to investigate the influence of thermal conditions experienced over multiple generations on performance. As the project’s focus was to understand transgenerational effects as a means for marine fish to acclimate and adapt to rapid environmental change, two future projected increases of +1.5°C and +3°C...

12. Putting the heat on insect reproduction: adaptive and mal-adaptive transgenerational effects through increasing thermal means and extremes

Extreme weather events like heatwaves, commonly defined as periods of five successive days where thermal maximums are 5oC greater than the long-term average, are predicted to be one of the most probable and hazardous challenges we face in a warming world. While natural populations have been showing climate related stress responses and extinctions for decades, the proximate mechanisms behind...

10. Transgenerational effects in a warming ocean – which parent has the greatest impact on the offspring?

Rachel Spinks

Rising sea temperature poses a significant threat to marine fishes. While current-day populations of reef fish suffer when exposed short-term to elevated temperatures, future warming will occur over numerous generations for most species. Recent studies have shown that when parents experience warmer ocean conditions throughout life, offspring performance improves. Yet we do not know the...
