Moss species and precipitation mediate experimental warming stimulation of growing season N2 fixation in subarctic tundra
<p>Climate change in high latitude regions leads to both higher temperatures and more precipitation but their combined effects on terrestrial ecosystem processes are poorly understood. In nitrogen (N) limited and often moss-dominated tundra and boreal ecosystems, moss-associated N<sub>2</sub> fixation is an important process that provides new N. We tested if high mean annual precipitation enhanced experimental warming effects on growing season N<sub>2</sub> fixation in three common arctic-boreal moss species adapted to different moisture conditions and evaluated their N contribution to the landscape level. We measured <em>in situ</em> N<sub>2</sub> fixation rates in <em>Hylocomium splendens</em>, <em>Pleurozium schreberi</em> and <em>Sphagnum</em> spp. from June to September in subarctic tundra in Sweden. We exposed mosses occurring along a natural precipitation gradient (mean annual precipitation: 571-1155 mm) to eight years of experimental summer warming using open-top chambers before our measurements. We modelled species-specific seasonal N input to the ecosystem at the colony and landscape level. Higher mean annual precipitation increased N<sub>2</sub> fixation, especially during peak growing seasons and in feather mosses. For <em>Sphagnum-</em>associated N<sub>2</sub> fixation,<em> </em>high mean annual<em> </em>precipitation reversed a small negative warming response. By contrast, in the dry-adapted feather moss species higher mean annual precipitation led to negative warming effects<em>.</em> Modelled total growing season N inputs for <em>Sphagnum </em>spp. colonies were 2-3 times that of feather mosses on an area basis. However, at the landscape level where feather mosses were more abundant, they contributed 50% more N than <em>Sphagnum</em>. The discrepancy between modelled estimates of species-specific N input via N<sub>2</sub> fixation at the moss core versus ecosystem scale exemplifies how moss cover is essential for evaluating the impact of altered N<sub>2</sub> fixation. Importantly, combined effects of warming and higher mean annual precipitation may not lead to similar responses across moss species, which could affect moss fitness and their abilities to buffer environmental changes. </p>
Fig. 1 in Response of Sphagnum Testate Amoebae to Drainage, Subsequent Re-wetting and Associated Changes in the Moss Carpet - Results from a Three Year Mesocosm Experiment
Fig. 1. Left: schematic cross-section through a mesocosm showing the peat and Sphagnum layer. Right: expected evolution of community structure or traits over the stress and recovery phases. At the onset of the experiment (T0) the community included the whole range of species living in pool, lawn and hummock, taken in a natural Sphagnum peatland. D1 is the point of maximum disturbance effect and R1 and R2 are sampling points during the recovery phase. Dotted lines represented the possible evolution of both species community structure and community weighted mean of functional traits in response to disturbance. Full recovery depended on the survival potential of species. The new equilibrium represents the situation when the local conditions or present species pool do not allow a fully recovery of original state. In our case this is due to the fact that some species are likely to be lost during the disturbance phase.
Fig. 3 in Response of Sphagnum Testate Amoebae to Drainage, Subsequent Re-wetting and Associated Changes in the Moss Carpet - Results from a Three Year Mesocosm Experiment
Fig. 3. Evolution of standardized effect size of mean pairwise distance between sampling plots relatively to a null model (random species matrix with respect to observed species richness, see text for details) of testate amoeba community weighted mean (CWM) of functional trait data from a Sphagnum fallax mesocosm experiment simulating water table changes. The mean pairwise distance represents the distance separating communities based on the pool of functional traits. Horizontal grey dotted line represents p-value of 0.05, points below the line are significantly different from the null model. Each replicate was represented separately, with a grey scale.
Fig. 2 in Response of Sphagnum Testate Amoebae to Drainage, Subsequent Re-wetting and Associated Changes in the Moss Carpet - Results from a Three Year Mesocosm Experiment
Fig. 2. Principal component analyses (PCA) of a) testate amoeba species and b) community weighted mean (CWM) of functional traits in Sphagnum fallax from a mesocosm experiment simulating water table changes. The species dataset was Hellinger transformed and the CWM data were scaled. Projection of descriptors (left) and samples (right), scaling 2. On the right plots, arrows represent the time line for each treatment (mean coordinates of the five sampling plots of each treatment and time). In both PCAs, axes 1 and 2 were the only significant axes and accounted respectively for 60.4% (species based) and 80.2% (CWM based) of the variance. Characteristic plots for wet and intermediate treatments were labelled.
