Comparison of water-use characteristics of tropical tree saplings with implications for forest restoration

Abstract Tropical forests are experiencing reduced productivity and will need restoration with suitable species. Knowledge of species-specific responses to changing environments during early stage can help identify the appropriate species for sustainable planting. Hence, we investigated the variabil...
