Characterizing the multivariate physiogenomic response to environmental change.

Area of Science:

• Marine biology
• Global change biology
• Genomics

Background:

• Global change is altering marine environments, posing challenges for species adaptation.
• Understanding population-specific responses to environmental stress is crucial for predicting species' resilience.
• Gene expression is often used as a proxy for stress, but its link to physiological traits needs further investigation in non-model organisms.

Discussion:

• This study investigates the physiogenomic underpinnings of coral responses to ocean acidification.
• It examines how differing historical exposures to acidification influence current population-level stress responses.
• The research integrates gene expression data with physiological measurements to understand adaptive mechanisms.

Key Insights:

• Two temperate marine coral populations exhibit distinct responses to ocean acidification, linked to their unique environmental histories.
• Specific gene expression patterns correlate with physiological traits, elucidating mechanisms of acclimation and adaptation.
• The findings highlight the role of physiogenomic feedbacks in determining coral fitness under global change.

Outlook:

• Further research can explore these physiogenomic feedbacks in other marine taxa facing global change.
• This work provides a framework for assessing the adaptive potential of populations to climate change.
• Understanding these mechanisms is vital for conservation efforts and predicting the future of marine ecosystems.
