Abstract Tropical forests dominate terrestrial photosynthesis, yet there are major contradictions in our understanding due to a lack of field studies, especially outside the tropical Americas. A recent study indicated that West African have among highest gross primary productivity (GPP) observed, contradicting models rank them lower than Amazonian forests. Here, we show possible reasons for this data-model mismatch. We found biometric GPP measurements on average 56.3% higher multiple global...
Traits are fundamental to understanding plant function and represent key variables for ecosystem modelling. An expanding class of models based on eco-evolutionary optimality (EEO) theory shows great potential in predicting trait–trait trait–environment relationships at both leaf whole-plant levels, via universal formulations that apply equally all functional types. According this gross primary production (GPP), the basis terrestrial carbon cycle, is jointly determined by...

Carbon (C) allocation is the process by which photosynthate partitioned to different functional pools, including leaves, woody tissues and fine roots. A long-standing, qualitative theory explains patterns of C as maximizing growth subject availability resources. Here we outline a quantitative model based on this theory. We define net carbon profit (NCP) total taken up photosynthesis, minus costs constructing maintaining leaves below-ground investments required supply them with water...

Understanding the distribution of assimilated carbon (C) among different plant parts is essential in explaining responses multiple functional traits to climate change. C allocation not adequately represented by current ecosystem models, and general explanatory framework with environmental conditions fragmented. Machine learning approaches applied large data sets have failed reveal principles underlying allocation. Here, we analyse a global set derived from several previous compilations test...
&lt;p&gt;Recently developed ecosystem models based on eco-evolutionary optimality hypotheses can predict many aspects of the carbon, water and nutrient economy ecosystems. These have focused various key plant functional traits their environmental controls. Gross primary production (GPP) is partly determined by ratio intercellular to ambient CO&lt;sub&gt;2&lt;/sub&gt; concentrations (&amp;#967;), which be inferred from leaf stable carbon isotope ratios...
