Carboniferous plant physiology breaks the mold

Area of Science:

• Paleobotany
• Geology
• Earth Surface Science

Background:

• The role of plants in shaping Earth's surface feedbacks over geologic time is a critical area of research.
• Recent findings suggest significant environmental modification by Carboniferous Period biomes, contrasting with the traditional view.
• This challenges the idea that active Earth surface moderation by plants began only with Mesozoic angiosperms.

Purpose of the Study:

• To detail the mechanistic underpinnings of modeling studies on Carboniferous plant ecophysiology.
• To illustrate the extraordinary ecophysiological capacities of plants during the Carboniferous Period.
• To address recent disputes regarding the environmental impact of early terrestrial flora.

Main Methods:

• Detailed mechanistic modeling of plant ecophysiology.
• Analysis of fossil evidence for plant capabilities.
• Comparative analysis of plant-environment interactions across geologic time.

Main Results:

• Carboniferous plants exhibited exceptional physiological capacities for environmental modification.
• Evidence supports substantial ecophysiological influence of these early biomes.
• The findings provide a mechanistic basis for understanding early plant-Earth feedbacks.

Conclusions:

• Plants in the Carboniferous Period played an active and significant role in shaping Earth's surface.
• This challenges the long-held view that such active moderation began much later in Earth's history.
• Understanding these early plant-driven feedbacks is crucial for reconstructing past environments.
