Research Highlight

The seasonal variation of plant productivity at Kaziranga forest, northeast India

In pre-monsoon, moderate rainfall and abundant radiation help enhance the photosynthetic activity, so productivity is high. Yellow bars in the top panel and a green tree in the lower panel depict this feature. From the monsoon season starting in June, the productivity decreases. But the respiration process, as shown by green bars in the top panel, exceeds the productivity. So the forest ecosystem emits a significant amount of carbon. The productivity (respiration) is measured by the amount of carbon synthesized (released) per square meter of the forest per month.
