Data from: Fertiliser application modulates the impact of interannual climate fluctuations and plant-to-plant interactions on the dynamics of annual species in a Mediterranean grassland
<p><span><strong><span>Background:</span></strong><span> Climate and land-use changes, which include the application of various types of organic and inorganic fertilisers, have been reducing the species diversity of Mediterranean grasslands and threatening their conservation. Annual plants are one of the most diverse functional groups of species in these grasslands, despite suffering competitive pressure from perennial herbaceous and woody species, and they are essential for ecosystem functioning and stability. </span></span></p> <p><span><strong><span>Aims:</span></strong><span> To quantify how fertilisation modulates the impact of plant-to-plant interactions and climate fluctuations on the dynamics of annuals in Mediterranean grasslands. We hypothesised that the application of sewage sludge would increase competition between functional groups, reducing the abundance of annuals in the long-term, but would buffer the negative impacts of drought on the year-to-year fluctuation of the diversity of annuals.</span></span></p> <p><span><strong><span>Methods:</span></strong><span> In a semi-natural species-rich Mediterranean grassland in northern Spain, we analysed the changes in the taxonomical and functional composition and diversity of annuals over 14 years in response to variations in the abundance of perennial herbaceous and woody species, climate fluctuations, and fertilisation with sewage sludge. We quantified separately the patterns of year-to-year fluctuations and long-term trends. </span></span></p> <p><span><strong><span>Results:</span></strong><span> The frequency and diversity of annuals decreased with a higher abundance of perennial herbaceous species, drought in June, and cold winters. The addition of sewage sludge decreased the abundance of annuals in the long-term, seemed to promote competition between annuals and other functional groups at an interannual scale, and mitigated the negative effects of drought and cold.</span></span></p> <p><span><span><strong>Conclusions:</strong> Fertilisation influences differently the temporal response of annuals to climate fluctuations and plant-to-plant interactions.</span></span></p>

Data from: Effects of arbuscular mycorrhizal fungi on plant invasion success driven by nitrogen fluctuations
<p>Both enemies and mutualists play crucial roles in shaping plant invasion processes. Recent studies have suggested that resource fluctuations could indirectly promote plant invasion through higher trophic levels, such as enemies. However, the influence of mutualists like arbuscular mycorrhizal fungi (AMF) on plant invasion under nitrogen fluctuations remains untested.</p> <p>We conducted a pot-mesocosm experiment using a three-factorial experimental design to assess the individual and interactive effects of nitrogen availability, nitrogen fluctuation and AMF on invasive success of alien plants. We grew nine invasive alien species alongside five different native communities in pot-mesocosms. These were then subjected to varied nitrogen availabilities (low vs high), nitrogen fluctuations (constant vs pulsed), and AMF presence or absence within a sterile substrate.</p> <p>We found that pulsed nitrogen supply increased the dominance of invasive alien species in low-nitrogen availability, regardless of the presence or absence of AMF inoculation. However, in high-nitrogen availability, pulsed nitrogen supply only enhanced this dominance in pots without AMF-inoculation. This was tentatively evidenced by the three-way interaction among nitrogen-availability, nitrogen-fluctuation and AMF-inoculation treatments. Furthermore, the dominance promotion by nitrogen addition was greater than that by AMF inoculation.</p> <p>Synthesis and applications: Our findings present, for the first time, evidence that AMF may play a crucial role in mediating the promotion effects of nitrogen fluctuations on alien plant invasion. To better understand the invasion process of alien plants and evaluate their impact on native communities, future research should integrate abiotic and biotic drivers into a single framework. Furthermore, our findings underscore the importance of prioritizing habitats with higher nutrient availability and variability for protection against alien plant invasions.</p>
