Seasonal flooding amplifies the positive asymmetric response of ecosystem carbon exchange along the precipitation gradient in saline wetlands

Key Points

• Ecosystem carbon exchange increases significantly with seasonal flooding, highlighting its critical role in wetland health.
• The asymmetric response indicates that positive effects dominate under certain precipitation conditions, particularly in saline areas.
• Observational analysis across varying levels of precipitation and flooding events assessed carbon dynamics in wetlands over multiple seasons.
• This study supports ecological strategies to manage saline wetlands, especially in a changing climate.
