“…To further test the theory, we gathered the published field measurement data on respiration rates of five tree species (Table S1) growing in natural forests from three separate studies (Fang, 1999; Zeng et al ., 2000; Ferrio et al ., 2018). The study site of Fang (1999) was in Beijing, China (39°58′N, 115°26′E) where the mean annual temperature (MAT) is c .…”

“…We also conducted glasshouse measurements of photosynthetic rates, respiration rates, and body mass for established seedlings and tree saplings of 165 species including 95 herbaceous and 70 woody species (see the Materials and Methods section). Finally, we compiled field measurements of respiration rates and the body mass of five large tree species growing in natural forests from several published studies (Fang, 1999; Zeng et al ., 2000; Ferrio et al ., 2018). All the species included in this study are listed in Table S1.…”

Summary Plant metabolism determines the structure and dynamics of ecological systems across many different scales. The metabolic theory of ecology quantitatively predicts the scaling of metabolic rate as a function of body size and temperature. However, the role of tissue water content has been neglected even though hydration significantly affects metabolism, and thus ecosystem structure and functioning. Here, we use a general model based on biochemical kinetics to quantify the combined effects of water content, body size and temperature on plant metabolic rates. The model was tested using a comprehensive dataset from 205 species across 10 orders of magnitude in body size from seeds to mature large trees. We show that water content significantly influences mass‐specific metabolic rates as predicted by the model. The scaling exponents of whole‐plant metabolic rate vs body size numerically converge onto 1.0 after water content is corrected regardless of body size or ontogenetic stage. The model provides novel insights into how water content together with body size and temperature quantitatively influence plant growth and metabolism, community dynamics and ecosystem energetics.

“…A number of studies have found light use efficiency reduced or respiration rates increased amongst smaller trees in the stand (Binkley et al 2013;O'Grady et al 2010;Fernández et al 2011;Tschieder et al 2012;Campoe et al 2013;Gspaltl et al 2013;Ex and Smith 2014;Gyenge and Fernández 2014). Ferrio et al (2018) studied growth, water use and respiration rates using the whole tree chamber methods of Mori et al (2010) (discussed in the second section of Supplementary Appendix A) of young (7-10 years old) Japanese cedar trees that were in the second phase of the Binkley et al model, growing in very dense stands (60,000 stems ha -1 ) so that the competitive interactions between taller and shorter trees would have been intense. They found that taller trees were more efficient in water use than smaller, suggesting they were compensating for increasing water stress to maintain their photosynthetic capacity.…”

“…This is because most of the studies on metabolic scaling have been based on indirect evidence and aimed to construct theoretical models to explain the exponent b , which has widely been assumed to be 3/4 as suggested by the WBE model [5–9]. The size scaling of individual organisms results from the sum of differentiated organs with distinctive functions and structure, each one showing contrasting responses under changing environments [11–13]. Therefore, evaluating metabolic rate of each organ is crucial to understand the scaling of metabolism associating with body size, namely mass or surface area.…”

26Terrestrial plants are rooted in one place, and therefore their metabolism must be flexible to 27 adapt to continuously changing environments. This flexibility is probably influenced by the 28 divergent metabolic traits of plant organs. However, direct measurements on organ-specific 29 metabolic rates are particularly scarce and little is known about their roles in determining 30 whole-individual meatabolism. To reveal this on seedlings of Fagus crenata, which is one of the 31 most widespread dominant genus in temperate deciduous broad leaf forests in the circum-polar 32 Northern Hemisphere, we measured respiration, fresh mass and surface area for total leaves, stems 33 and roots of 55 individuals in two years from germination and analyzed their relationships with 34 individual metabolism. Proportion of roots to whole plant in mass increased from approximately 35 17% to 74%, and that in surface area increased from about 11% to 82% in the two years. 36Nonetheless, the increment of the proportion of root respiration to whole-plant respiration was from 37 9.2% to only 40%, revealing that the increment in mass and surface area of roots was much larger 38 than the increment in energetic cost. As a result, only the roots showed a substantial decline in both 39 respiration/surface area and respiration/mass among the three organs; roots had about 90% decline in 40 their respiration/surface area, and 84% decline in their respiration/mass, while those in leaves and 41 stems were relatively constant. The low-cost and rapid root development is specific to the two years 42 after germination and would be effective for avoiding water and nutrient deficit, and possibly helps 43 seedling survival. This drastic shift in structure and function with efficient energy use in 44 developmental change from seeds to seedlings may underpin the establishment of F. crenata forests. 45 We discuss significance of lowering energetic cost for various individual organisms to effectively 46 acquire resources from a wide perspective of view. 47 48 3 50 support various biological processes as a base for adaptation to changing environments [1,2]. 51Therefore, the metabolic rate has profound physiological, ecological and evolutionary implications 52 [3,4], which would be a key to understand and predict the effects of climate change on organisms 53 and ecosystems [1,2]. 54In general, the metabolic rate (i.e. respiration rate, R) of individual organisms scales with body 55 size (X), and is usually described as the simple power function of body mass:where a is a normalization constant, and b is the scaling exponent (slope on the log-log coordinates) 58[5-7]. The equation (1) represents the emergent outcomes of the metabolism of individuals under 59 various constraints [2,8,9]. Therefore, to obtain a mechanistic insight into the regulation of scaling of 60 metabolic rate, we need empirical evidence of whole-organism measurements. However, little is 61 known about the relationships between metabolic rate and body size with the reliable data from sm...
