Abstract Tropical forests take up more carbon (C) from the atmosphere per annum by photosynthesis than any other type of vegetation. Phosphorus (P) limitations to C uptake are paramount for tropical and subtropical around globe. Yet generality photosynthesis-P relationships underlying these in question, hence not represented well terrestrial biosphere models. Here we demonstrate dependence processes on both leaf N P concentrations. The regulation photosynthetic capacity was similar across...

Abstract Woody debris (WD) represents a globally significant carbon stock and its decomposition returns nutrients to the soil while providing habitat microbes, plants animals. Understanding what drives WD is therefore important. rates differ greatly among species. However, role of bark in process remains poorly known. We ask how, how much, interspecific variation functional traits related growth protection have afterlife effects on wood, partly mediated by examine roles cover throughout wood...
The frequency of extreme drought events has been rising worldwide, but due to its unpredictability, how plants will respond remains poorly understood. Here, we aimed characterize the hydraulics and photosynthesis savanna drought, tested whether they can subsequently recover after drought. There was an in 2019 Southwest (SW) China. We investigated photosynthetic gas exchange, leaf-, stem-, whole-shoot hydraulic conductance 18 plant species with diverse leaf habits (deciduous, semi-deciduous...
Small RNAs (sRNAs) are a class of molecules capable perceiving environmental changes and exerting post-transcriptional regulation over target gene expression, thereby influencing bacterial virulence host immune responses. Pseudomonas plecoglossicida is pathogenic bacterium that poses significant threat to aquatic animal health. However, the regulatory mechanisms sRNAs in P. remain unclear. This study focused on sRNA113, previously identified as potential regulator fliP gene, key component...
Habitat heterogeneity and dispersal limitation are widely considered to be the two major mechanisms in determining tree species distributions. However, few studies have quantified relative importance of these at different life stages trees. Moreover, rigorous quantification effects dominant distributions has seldom been explored. In present study, we tested hypothesis that distribution is regulated by history stages. particular, hypothesised regulates trees early environmental factors...
