Naturally, terrestrial ecosystems are a huge sink for atmospheric carbon dioxide. However, it remains to be seen if this capacity will increase, decrease, or remain the same in the future climate. The research we do is part of a nationwide effort to tackle this question. Among the major ecosystems of the world, temperate forests of conifers and broad-leafed plants such as maples, oaks and birches form the largest terrestrial sink for carbon, and recent studies indicate that temperate forests of North America are a larger carbon sink than previously thought. Even if the system's capacity for carbon sequestration increases with higher atmospheric carbon dioxide levels, there are unanswered questions about species diversity.
Different species appear to have different responses to elevated levels of carbon dioxide.
But if it is true different species respond differently, this has tremendous implications for biodiversity. Some species within a community might have a competitive advantage as greenhouse gases rise, and some might die off.
