Patterns of nitrogen and phosphorus pools in terrestrial ecosystems in China
<p>Recent increases in atmospheric carbon dioxide (CO<sub>2</sub>) and temperature relieve the limitation of these two on terrestrial ecosystem productivity, while nutrient availability constrains the increasing plant photosynthesis more intensively. Nitrogen (N) and phosphorus (P) are critical for plant physiological activities and consequently regulates ecosystem productivity. Here, for the first time, we mapped N and P densities of leaves, woody stems, roots, litter and soil in forest, shrubland and grassland ecosystems across China, based on an intensive investigation in 4175 sites, covering species composition, biomass, and nutrient concentrations of different tissues of living plants, litter and soil. Forest, shrubland and grassland ecosystems in China stored 7665.62 × 10<sup>6</sup> Mg N, with 7434.53 × 10<sup>6</sup> Mg (96.99%) fixed in soil (to a depth of one metre), and 32.39 × 10<sup>6</sup> Mg (0.42%), 59.57 × 10<sup>6</sup> Mg (0.78%), 124.21 × 10<sup>6</sup> Mg (1.62%) and 14.92 × 10<sup>6</sup> Mg (0.19%) in leaves, stems, roots and litter, respectively. The forest, shrubland and grassland ecosystems in China stored 3852.66 × 10<sup>6</sup> Mg P, with 3821.64 × 10<sup>6</sup> Mg (99.19%) fixed in soil (to a depth of one metre), and 3.36 × 10<sup>6</sup> Mg (0.09%), 14.06 × 10<sup>6</sup> Mg (0.36%), 11.47 × 10<sup>6</sup> Mg (0.30%) and 2.14 × 10<sup>6</sup> Mg (0.06%) in leaves, stems, roots and litter, respectively. Our estimation showed that N pools were low in northern China except Changbai Mountains, Mount Tianshan and Mount Alta, while relatively higher values existed in eastern Qinghai-Tibetan Plateau and Yunnan. Southern China held quite small P pools, which may limit some plant-related process. P densities in plant organs were higher in the North and East China, while soil P density was higher in the South and West China. These patterns of N and P densities could potentially improve existing earth system models and large-scale researches on ecosystem nutrients.</p>
Data from: Litter movement pathways across terrestrial-aquatic ecosystem boundaries affect litter colonization and decomposition in streams
1. Streams and their riparian zones are connected by spatial flows of organic matter, and constitute a model example of a meta-ecosystem. Fluxes of leaf litter from the riparian zone to the stream are a major energy source in stream food webs. Leaf litter can enter the stream vertically, falling from the tree and into the stream, or laterally, washing into the stream after a period of exposure in the terrestrial ecosystem. The latter can contribute up to 23% to the total amount of litterfall entering streams. 2. To determine if decomposition, microbial and invertebrate colonization of lateral litter inputs are similar to those of vertical inputs, we assessed leaf decomposition of alder, poplar and a 1:1 mixture of the two species in three scenarios across a gradient of terrestrial:aquatic exposures. 3. Overall decomposition was explained by a negative exponential model and decreased with the increase in the period of terrestrial exposure in all cases. Invertebrate colonization tended to decrease with the increase in the period of terrestrial exposure, but total invertebrate richness and biomass were more affected by litter type than by the exposure scenario, attaining higher values in the mixture than in the species alone. 4. As the length of exposure in the terrestrial ecosystem increased, in-stream decomposition rates of leaf litter decreased. Comparing leaf species treatments, alder decomposition rates were faster than poplar and the alder-poplar mixture. 5. The richness of the aquatic hyphomycete community colonizing leaf litter after submergence decreased and sporulation rates were strongly inhibited with an increasing terrestrial exposure period. While fungi colonizing leaf litter exposed only in the stream invested in rapid reproduction, fungi colonizing litter with prior terrestrial exposure built up more biomass. 6. We conclude that the path taken by the litter fluxes has important effects on the functioning of the receiving ecosystem. Studies relying only on the fate of freshly abscissed leaf litter (vertical inputs) may not present a complete picture of the decomposition process in streams and may have been overestimating the overall richness and reproductive activity of the aquatic hyphomycetes colonizing leaf litter.

Supporting Data for: Assessing the potential of amino acid δ13C and δ15N analysis in terrestrial and freshwater ecosystems
<p>Understanding the structure and dynamics of food webs requires accurate estimates of energy flow among organisms. Bulk tissue carbon (<em>δ</em><sup>13</sup>C) and nitrogen (<em>δ</em><sup>15</sup>N) isotope analysis is often used to this end, however, the limitations of this technique can outweigh the benefits. The isotope analysis of individual amino acids is being increasingly employed to trace energy flow and estimate consumer trophic level. Central to this compound-specific approach are the concepts of essential amino acid (AA<sub>ESS</sub>) <em>δ</em><sup>13</sup>C fingerprinting and amino acid (AA) <em>δ</em><sup>15</sup>N beta-values, both of which have been understudied and are poorly constrained in terrestrial and freshwater producers.</p> <p>We present AA<sub>ESS</sub> <em>δ</em><sup>13</sup>C data for 112 terrestrial and freshwater producers collected from two aridland habitats in the northern Chihuahuan Desert (New Mexico, USA) and AA <em>δ</em><sup>15</sup>N data for a subset (n=28) of these samples. We characterized AA<sub>ESS</sub> <em>δ</em><sup>13</sup>C fingerprints by performing linear discriminant analysis on the <em>δ</em><sup>13</sup>C values of isoleucine, leucine, lysine, phenylalanine, threonine, and valine for four producer groups – C<sub>3</sub> plants, C<sub>4</sub> plants, CAM plants, and filamentous green algae. We explored potential biochemical mechanisms underlying these AA<sub>ESS</sub> <em>δ</em><sup>13</sup>C fingerprints by calculating differences between the <em>δ</em><sup>13</sup>C values of AA<sub>ESS</sub> products and their AA precursors. This allowed us to estimate and compare isotopic discrimination for specific AA<sub>ESS</sub> synthesis pathways across producer groups.</p> <p>We found near perfect separation of AA<sub>ESS</sub> <em>δ</em><sup>13</sup>C fingerprints among producer groups; all groups reclassified with >95% success within our multivariate framework. We also found varied isotopic discrimination for specific AA<sub>ESS</sub> synthesis pathways among producer groups. Contrary to previous studies, we found no differences in beta-values between terrestrial C<sub>3</sub> and C<sub>4</sub> plants for any trophic-source AA pairing. Furthermore, we found that Lys <em>δ</em><sup>15</sup>N values were less variable and more closely related to bulk tissue <em>δ</em><sup>15</sup>N values than Phe <em>δ</em><sup>15</sup>N values in terrestrial and freshwater producers.</p> <p><span><span><span><span><span>We conclude that AA<sub>ESS</sub> <em>δ</em></span></span></span></span></span><sup>13</sup><span><span><span><span><span>C fingerprints are a higher-resolution tracer for freshwater food webs where instream algae have overlapping bulk tissue <em>δ</em></span></span></span></span></span><sup>13</sup><span><span><span><span><span>C values with terrestrial C<sub>3</sub> plants.

Data from: Contrasting nitrogen cycling between herbaceous wetland and terrestrial ecosystems inferred from plant and soil nitrogen isotopes across China
<p><span>Understanding nitrogen (N) cycling in different ecosystems is crucial to predicting and mitigating the global effects of altered N inputs. Although wetlands have always been assumed to differ largely from terrestrial ecosystems in N cycling, evidence from direct comparison from the field along wide environmental gradients is lacking. Here, we hypothesized strong coupling of plant and soil δ<sup>15</sup>N in terrestrial ecosystems due to lower N inputs and losses but weak coupling of plant and soil δ<sup>15</sup>N in wetlands because of higher N inputs and losses.</span></p> <p><span>We performed a large-scale field investigation on 26 pairs of herbaceous wetland and terrestrial sites across China covering 21 degrees of latitude and determined natural abundance of nitrogen isotopes (δ<sup>15</sup>N) in soils and leaves of 346 dominant and subordinate plant species. We analysed the relationships between leaf and soil δ<sup>15</sup>N and their drivers including plant functional types in these two types of ecosystems.</span></p> <p><span>Plant functional types including mycorrhizal type and N2-fixing status had consistently significant influences on leaf δ<sup>15</sup>N in herbaceous wetland and terrestrial ecosystems. Leaf δ<sup>15</sup>N increased significantly with soil δ<sup>15</sup>N within and across mycorrhizal types in both ecosystems, and, as hypothesized, the relationships were stronger and steeper in terrestrial than in wetland ecosystems. Moreover, leaf and soil δ<sup>15</sup>N were positively and significantly correlated within both N<sub>2</sub>-fixers and non-fixers in terrestrial ecosystems and within only non-N<sub>2</sub>-fixers in wetlands. At the community level, we also found more highly significant relationships between leaf and soil δ<sup>15</sup>N in terrestrial than in wetland ecosystems. Besides plant functional types, climatic and soil factors contributed to the variation in leaf δ<sup>15</sup>N in both ecosystems.</span></p> <p><span><em>Synthesis.</em> Weaker relationships between plant and soil δ<sup>15</sup>N in wetlands at species and community levels supports the hypothesis that larger N inputs and losses lead to weaker coupling in the plant-soil systems in wetlands than in terrestrial ecosystems. This provides strong evidence from a large spatial scale for contrasting N cycling in these two types of ecosystems regardless of plant functional type in terms of nutrient uptake strategy. Our findings add to our predictive power of ecosystem N dynamics under environmental changes, e.g. land-use changes and elevated N inputs.</span></p>
