Soil respiration is correlated with rainfall and soil moisture at multiple temporal scales in a seasonal wet tropical forest.

D. Chakravarthy, H. V. Raghavendra, J. Ratnam, M. Sankaran

This study examines soil respiration in tropical forests, finding it correlates with rainfall and soil moisture across multiple time scales, but not temperature, suggesting monsoon patterns drive future responses.

Structure and dynamics of secondary and mature rainforests: insights from South Asian long-term monitoring plots

A. Murali, S. Kasinathan, K. Bhat, J. Ratnam, M. Sankaran, D. Mudappa, T. R. S. Raman, A. M. Osuri

The paper compares tree community and carbon dynamics in mature and secondary rainforests over five years, finding higher carbon stocks and diversity in mature forests but greater carbon accrual in secondary forests.

Understanding the variation in wood densities of trees and its implications for carbon assessments

K. Teegalapalli, C. K. Pandey, A. Osuri, J. Ratnam, M. Sankaran

The paper quantifies intraspecific and interspecific variation in wood density across tree genera and evaluates the accuracy of using genus averages for carbon stock estimation.

Climate and vegetation collectively drive soil respiration in montane forest-grassland landscapes of the southern Western Ghats, India

A. A. Joshi, J. Ratnam, H. Paramjyothi, M. Sankaran

This study examines how land-use changes affect soil respiration in montane ecosystems, finding that vegetation type significantly influences carbon cycling despite similar soil conditions.
