Solar Radiation and Water Stress Are Major Environmental Drivers of the Latitudinal Pattern of Leaf Si Concentration in Woody Plants
Aim
Silicon (Si) enhances plants' resistance to environmental stress. Forests absorb much more Si than other vegetation types, making it crucial to comprehend the factors influencing Si concentration in woody plants for studying global terrestrial Si cycling, especially under significant environmental changes. Here, we analyze the latitudinal pattern of leaf Si concentration in woody plants and identify its main environmental drivers.
Location
Worldwide; covering six continents except Antarctica.
Time Period
1945–2023.
Major Taxa Studied
Terrestrial woody plants.
Methods
We compiled a dataset of leaf Si concentration for wild terrestrial woody plants and analysed the latitudinal patterns of leaf Si concentration and their environmental drivers.
Results
We revealed a significant unimodal latitudinal pattern of leaf Si concentration in woody plants, peaking in subtropical high-pressure regions. Solar radiation and water stress are the main environmental drivers of this pattern. Additionally, different plant functional groups with distinct concentrations but similar latitudinal trends of leaf Si, together with their latitudinal distribution shifts, intensify this pattern.
Main Conclusions
High leaf Si concentration is an important adaptive strategy for woody plants to mitigate the adverse effects of intense solar radiation and water stress in subtropical high-pressure regions. The biogeography of leaf Si in woody plants revealed here provides insight into the macro-evolution of Si in plant stress resistance and highlights its important role in sustaining forest productivity under global climate change.
期刊介绍：
Global Ecology and Biogeography (GEB) welcomes papers that investigate broad-scale (in space, time and/or taxonomy), general patterns in the organization of ecological systems and assemblages, and the processes that underlie them. In particular, GEB welcomes studies that use macroecological methods, comparative analyses, meta-analyses, reviews, spatial analyses and modelling to arrive at general, conceptual conclusions. Studies in GEB need not be global in spatial extent, but the conclusions and implications of the study must be relevant to ecologists and biogeographers globally, rather than being limited to local areas, or specific taxa. Similarly, GEB is not limited to spatial studies; we are equally interested in the general patterns of nature through time, among taxa (e.g., body sizes, dispersal abilities), through the course of evolution, etc. Further, GEB welcomes papers that investigate general impacts of human activities on ecological systems in accordance with the above criteria.
