Precipitation manipulation and terrestrial carbon cycle: the roles of treatment magnitude, experimental duration, and background climate
<p><b>Aim: </b><a name="_Hlk62140683">Precipitation manipulation experiments have shown diverse terrestrial carbon (C) cycling responses when the ecosystem is subjected to different magnitudes of altered precipitation, various experimental durations, or heterogeneity in local climates. However, how these factors combine to affect C cycle responses to changes in precipitation remains unclear.</a></p> <p><b>Location</b>: Global.</p> <p><b>Time period</b>: 1990–2019.</p> <p><b>Major taxa studied</b>: Terrestrial ecosystems.</p> <p><b>Methods</b>: Using observations from 230 published studies in which precipitation was manipulated and terrestrial C cycling variables were measured, we conducted a global meta-analysis to investigate responses of diverse C cycle processes to altered precipitation, including gross ecosystem productivity, ecosystem respiration, net ecosystem productivity, ecosystem carbon use efficiency, net primary productivity, aboveground and belowground net primary productivity, aboveground and belowground biomass, shoot:root ratio, soil respiration, and soil microbial biomass C.</p> <p><b>Results</b>: <a name="_Hlk50913646"></a><a name="_Hlk62140761">We found that C cycling responses correlated linearly and positively with the magnitude of precipitation treatments, in that C cycling variables increased under increased precipitation, and decreased under decreased precipitation. </a>We also detected that the responses of net primary productivity (NPP) and its aboveground component (ANPP) to altered precipitation weakened with experimental duration. Furthermore, gross ecosystem productivity, ecosystem respiration, and net ecosystem productivity had larger responses to precipitation treatments of greater magnitude over shorter time periods. The response of soil respiration, a key component of the C budget in most terrestrial ecosystems, particularly depended on the background climate. Local temperature and precipitation not only influenced the magnitude of the response of soil respiration to altered precipitation but also affected its sensitivity to the magnitude of the precipitation treatments, with higher sensitivities in the response of soil respiration to treatment magnitude at drier and colder sites.</p> <p><b>Main conclusions</b>: <a name="_Hlk62140806">Our findings highlight the importance of the interactions between the magnitude of precipitation treatments, their duration, and local climate in the response of ecosystem C cycling to precipitation, which is critical to better understanding and projecting ecosystem C processes and functioning under changing precipitation regimes.</a></p>
Magnitude-duration relationships of physiological sensitivity and environmental exposure improve climate change vulnerability assessments
<p class="MsoNormal"><span>Integrating thermal physiology with environmental temperature is essential to understanding distributions of species and vulnerability to climate change. Warming tolerance—the difference between an organism's maximum thermal tolerance (T<sub>max</sub>) and maximum habitat temperature (T<sub>hab</sub>)—is frequently used to integrate organismal sensitivity and environmental exposure. Traditionally, applications of warming tolerance define T<sub>max</sub> and T<sub>hab</sub> as invariable magnitudes, yet tolerance magnitude depends on exposure duration and diel temperature cycles expose organisms to a range of temperature magnitudes and durations. How traditional (<em>i.e.</em>, acute) estimates of warming tolerance compare to estimates from prolonged exposures remains poorly understood. In this study, magnitude-duration curves for tolerances of one cold-water, two cool-water, and one warm-water species of freshwater fish were compiled from the literature and compared to magnitude-duration exposures from 66 streams across the eastern United States. Warming tolerances were estimated for exposure durations spanning 0.01 to 24 hours. Current acute (0.01 hours) warming tolerances ranged from median 6.30°C for the cold-water species to 9.68°C for the warm-water species. The lowest warming tolerances corresponded to prolonged exposures lasting median 3.85 to 5.30 hours among species and were 2.51 to 4.38°C lower than acute estimates. Although acute estimates remained positive in historically occupied and unoccupied streams (6.30°C versus 2.33°C), estimates based on prolonged exposure were positive at occupied streams of the cold-water species but transitioned to negative in unoccupied streams (2.19°C versus -1.12°C). Acute warming tolerances for the cold-water species also remained positive under future climate (6.29 to 4.23°C) but approached zero at prolonged durations (2.19 to 0.09°C) and transitioned to negative for 47.2% of streams. Results demonstrate that acute measures of T<sub>max</sub> and T<sub>hab</sub> overestimate warming tolerances and therefore underestimate climate change vulnerability. Integrating magnitude-duration relationships into warming tolerance estimates can elucidate physiological mechanisms underlying species distributions and can improve accuracy of climate change vulnerability assessments.</span></p>

Root functional traits determine the magnitude of the rhizosphere priming effect among eight tree species
<p><span>Rhizosphere priming effect </span>can accelerate or decelerate the decomposition of soil organic matter. Using a natural abundance <sup>13</sup>C tracer method allowing partitioning of native soil organic carbon (SOC) decomposition and plant rhizosphere respiration, we studied the effects of eight tree species on the strength of the rhizosphere priming. All tree species enhanced the rate of SOC decomposition, by 82% on average. <span>M</span><span>ean diameter of first-order roots and root exudate-derived respiration</span><span> were positively correlated with the RPE</span><span>, together explaining a large part of the observed variation in the RPE (<em>R<sup>2</sup></em> = 0.72), whereas root branching density was negatively associated with the RPE. Path analyses further suggested that mean diameter of first-order roots was the main driver of the RPE owing to its positive direct effect on the RPE and its indirect effects via root exudate-derived respiration and root branching density. </span>These results demonstrate that the magnitude of the RPE is regulated by complementary aspects of root morphology, architecture and physiology, implying that comprehensive approaches are needed to reveal the multiple mechanisms driving plant effects on the RPE.</p>
Plant growth strategy determines the magnitude and direction of drought-induced changes in root exudates in subtropical forests
<p><span>Root exudates are an important pathway for plant-microbial interactions and are highly sensitive to climate change.</span> <span>However, how extreme drought affects root exudates and the main components, as well as species-specific differences in response magnitude and direction, are poorly understood. In this study, root exudation rates of total carbon (C) and its components (e.g., sugar, organic acid, and amino acid) were measured under the control and extreme drought treatments (i.e., 70% throughfall reduction) by <em>in situ</em> collection of four tree species with different growth rates in a subtropical forest. We also quantified soil properties, root morphological traits, and mycorrhizal infection rates to examine the driving factors underlying variations in root exudation. Our results showed that extreme drought significantly decreased root exudation rates of total C, sugar, and amino acid by 17.8%, 30.8%, and 35.0%, respectively, but increased root exudation rate of organic acid by 38.6%, which were largely associated with drought-induced changes in tree growth rates, root morphological traits, and mycorrhizal infection rates. Specifically, trees with relatively high growth rates were more responsive to drought for root exudation rates compared to those with relatively low growth rates, which were closely related to root morphological traits and mycorrhizal infection rates. These findings highlight the importance of plant growth strategy in mediating drought-induced changes in root exudation rates. The co-ordinations among root exudation rates, root morphological traits, and mycorrhizal symbioses in response to drought could be incorporated into land surface models to improve the prediction of climate change impacts on rhizosphere C dynamics in forest ecosystems. </span></p>
Data: The magnitude and pace of photosynthetic recovery after wildfire in California ecosystems
<p>Wildfire modifies the short- and long-term exchange of carbon between terrestrial ecosystems and the atmosphere, with impacts on ecosystem services such as carbon uptake. Dry western United States forests historically experienced low-intensity, frequent fires, with patches across the landscape occupying different points in the fire-recovery trajectory. Contemporary perturbations, such as recent severe fires in California, could shift the historic stand-age distribution and impact the legacy of carbon uptake on the landscape. Here we combine flux measurements of gross primary production (GPP) and chronosequence analysis using satellite remote sensing to investigate how the last century of fires in California impacted the dynamics of ecosystem carbon uptake on the fire-affected landscape. A GPP recovery trajectory curve of more than five thousand fires in forest ecosystems since 1919 indicated that fire reduced GPP by 157.4 ± 7.3 gCm<sup>-2</sup>yr<sup>-1</sup> (mean ± standard error, n=1926) in the first year after fire, with average recovery to pre-fire conditions after ~12 years. The largest fires in forested ecosystems reduced GPP by 393.8 ± 15.7 gCm<sup>-2</sup>yr<sup>-1</sup> (n=401) and took more than two decades to recover. Recent increases in fire severity and recovery time have led to nearly 9.9 ± 3.5 MMT CO<sub>2</sub> (3-year rolling mean) in cumulative forgone carbon uptake due to the legacy of all fires on the landscape, complicating the challenge of maintaining California's natural and working lands as a net carbon sink. Understanding these changes is paramount to weighing the costs and benefits associated with fuels management and ecosystem management for climate change mitigation.</p>
