Data from: Plastic responses of belowground foraging traits to soil phosphorus-rich patches across 17 coexisting AM tree species in a subtropical forest
<p><span>1. </span><span>Belowground plastic responses to soil nutrient "hot-spots" form a key nutrient foraging strategy of plants coexisting in natural ecosystems. However, it is unclear how plant species differ in these belowground plastic responses and how they co-vary.</span></p> <p><span>2. </span><span>Plastic responses to soil phosphorus (P)-rich patches of absorptive root, mycorrhizal, and exudation traits of 17 co-existing arbuscular mycorrhizal (AM) tree species in a subtropical evergreen broad-leaved forest were investigated using a root bag method.</span></p> <p><span>3. </span><span>There was considerable variation and heterogeneity in species-specific responses to P-rich patches. Negative log response ratios usually occurred for high-cost traits and positive log response ratios for low-cost traits. There were tradeoffs in the plastic responses between root acid phosphatase activity and extraradical hyphal length, which were unaffected by phylogeny, and between root acid phosphatase activity and specific root length. Thicker-rooted species responded to P-rich patches more through root exudation plasticity than mycorrhizal plasticity. Thinner-rooted species relied more on mycorrhizal plasticity.</span></p> <p><span>4. </span><em><span>Synthesis</span></em><span>. Our results revealed diverse P foraging strategies comprising different combinations of plastic adjustments in absorptive root, mycorrhizal, and exudation traits among coexisting AM tree species, which suggest the potential for complementary exploitation of different soil P sources.</span></p>

Cations make a difference: Soil nutrient patches and fine-scale root abundance of individual species in a mountain grassland
<p><span>1. Root densities in the field vary at the centimetre scale, but we have no information </span><span>on </span><span>whether this variation is linked to variation in nutrient concentrations and availability. Roots of many species are able to proliferate in nutrient-rich patches in controlled conditions in culture, but because data on nutrient concentrations and, in particular, on their temporal stability in the field are scarce, we do not know to what extent root distribution in the soil bears traces of such a response.</span></p> <p><span>2. Here</span><span>,</span><span> we linked </span><span>centimetre</span><span>-scale measurements of soil nutrient concentrations over a period of 6 weeks with estimation of root biomass and its species composition at the same points to determine whether there is any association between the two. In addition to phosphorus, nitrate and ammonium, we determined</span><span> the</span><span> concentrations of metal cations (magnesium, calcium and potassium). We used qPCR to determine</span><span> the</span><span> quantities of individual species in the root biomass samples.</span></p> <p><span>3. We found that calcium and magnesium (and to a lesser degree phosphorus and potassium) showed fine-scale patchiness that was stable over the duration of the study (6 weeks) and </span><span>was</span><span> consistent over all these elements. Nutrient patches were associated with high root biomass and </span><span>the </span><span>occurrence of roots of several species. Such patches are formed primarily by elements with known low mobility in soil (cations, phosphorus). In contrast, nitrogen ions showed overwhelmingly high temporal variation with no relationship between root density and nitrogen concentration.</span></p> <p><span>4. Soil nutrient concentrations thus constitute a multidimensional signal. Some elements strongly </span><span>vary</span><span> in time, while some are much more stable and thus form stable patches that permit root response over periods of weeks or months. Among them, calcium and magnesium play an important role in forming soil heterogeneity at a scale comparable to the scale at which fine root densities also vary. As these cations affect a number of plant functions, their association with higher root densities confirms their role in growth dynamics of terrestrial ecosystems.</span></p>
