Perspectives

ECOLOGY:
Looking Beneath the Surface

Jack A. Morgan

Global climate change is expected to have ecological consequences. Field studies attempting to simulate these effects often do not investigate multiple environmental factors and may therefore miss some important feedbacks. In his Perspective, Morgan highlights the multiple-factor, 3-year field study reported by Shaw et al., who find that increasing CO2 may inhibit plant growth. Morgan discusses possible explanations for this counterintuitive result, but cautions that short-term, transient responses may not reflect the long-term ecological response.
