Multi-trait variations of Phaeodactylum tricornutum Bohlin populations in ambient, warming, elevated CO2 and elevated CO2 + warming regimes across CO2 gradients.

The PCAs of multiple traits of Phaeodactylum tricornutum Bohlin populations among different regimes (a), individual CO2 levels (b) or CO2 clusters (c).

🔎 #Warming & #ElevatedCarbonDioxide ➡️ #PhaeodactylumTricornutumBohlin (CO2 gradients)
Results:
1️⃣ Populations adapted to different environmental regimes exhibit multi-trait variation.
2️⃣ The variability driven by long-term adaptation > by short-term CO2 changes.

Percent changes in litter mass loss under eCO2 across (a) ecosystems, (b) vegetation types, (c) litter types and (d) experimental duration.

Percent changes in litter C release under eCO2 across (a) ecosystems, (b) vegetation types, (c) litter types and (d) experimental duration.

⭐ #ElevatedCarbonDioxide (eCO2) ➡️ the decomposition of #LitterMass on the soil surface❓
Observation indicators:
1️⃣litter mass loss;
2️⃣carbon (C) and nitrogen (N) release.
Degree of impact:
1️⃣forests > croplands and grasslands;
2️⃣broadleaved > coniferous;
3️⃣root > leaf and stem.
