Warming, nitrogen deposition and provenance shift above-belowground insect interactions and host compensatory growth

Above-belowground insect herbivore interactions and plant compensatory growth are crucial for reshaping the fitness of invasive plants, and it is likely that climate warming, nitrogen (N) deposition, and plant provenance influence this interaction and growth in a complex way. We performed an experiment with Solidago canadensis from home and introduced ranges, leaf-chewing Spodoptera litura, and root-feeding Protaetia brevitarsis under climate warming and N deposition, and addressed how these abiotic stressors and plant provenance jointly shaped the reciprocal effects between S. litura and P. brevitarsis and the compensatory growth of S. canadensis after herbivory. Under ambient conditions, S. litura and P. brevitarsis inhibited each other on the basis of growth; warming, N addition or warming plus N addition shifted or even reversed this competition depending on provenance. While the survival-based above-belowground interactions differed from growth-based ones, warming or warming plus N..., A study platform (i.e., a long-term experiment) was established at the Chengdu field site (30.67ºN, 104.06ºE) in June 2012. The purpose of this experiment was to provide identical climate scenarios and seeds for subsequent experiments and to minimize maternal effects. The study site belongs to a subtropical climate, where the mean annual precipitation is 918 mm and the mean annual temperature is 18.6 °C, and the soil is a ferralsol (Peng et al., 2019). The long-term experiment involved warming, N addition, and plant provenances, each with two levels. Experimental warming was achieved by heating with MSR-2420 infrared radiators, and the heater was suspended 1.5–2.0 m above the soil surface, roughly increasing air temperatures by 2 °C (Peng et al., 2019). Nitrogen enhancement was achieved by adding ammonium nitrate (NH4NO3) on the soil surface: adding a pulse of 1 g N m–2 as an aqueous ammonium nitrate solution on four occasions per year. Plant seeds were collected from the native and int..., , # Warming, nitrogen deposition and provenance shift above-belowground insect interactions and host compensatory growth
