“…Across studies, preference for NH 4 + , NO 3 − or a combination of the two often differed among species (Falkengren‐Grerup, ; Britto & Kronzucker, ), potentially leading to differences in plant performance and population growth. However, we know little about the responses of invasive plants to inorganic N forms (Huangfu et al ., ).…”

“…Invasion of B . alba is associated with changes in the soil environment of coastal zones, including pH and EC, predominantly due to selective absorption of N forms associated to a strong preference for ammonium (NH 4+ ) over nitrate (NO 3- ) and alkaline substances in litter and root exudates of invasion plants [ 53 , 54 ]. Obvious changes in pH and EC may interactively influence phylogenetic diversity associating with bacterial community functions [ 55 ].…”

The effects of Bidens alba invasion on soil bacterial communities across different coastal ecosystem land-use types in southern China

Environments in both biotic and abiotic ecosystems have been affected by the colonization of non-native flora. In this study, we examined the effect of Bidens alba invasion on different land-use types along a coastline in southern China. Bacterial communities in each site were determined using 16S rDNA sequencing, and soil physicochemical properties were analyzed using standard methods. Although our results indicated that B . alba invasion did not have a significant effect on the alpha diversity of bacteria, it caused significant differences in soil bacterial community composition between invaded and uninvaded soil across different land-use types. Beta diversity and several physicochemical properties in forest, orchard and waterfront environments were recorded to be more susceptible to B . alba invasion. A high proportion of the variation of bacterial communities can be explained by a combination of environmental variables, indicating that environmental selection rather than plant invasion is a more effective process in coastal microbial assemblages. By comparing topological roles of shared OTUs among invaded and uninvaded soil, keystone taxa in invaded soil were identified. Acidobacteria was the major phyla involved in the invasive process which could be driven by environmental selection. How key phyla react in our experiment should be verified by further studies.

“…This increase in grass biomass production with increasing soil N availability while there was no short-term response of the tree seedlings suggests a potential advantage for the grass in habitats on N-rich soils or in future scenarios with increased atmospheric N deposition compared to the native trees. This link between high resource availability and success of invasive species has been explored in previous studies (e.g., Badgery et al 2005, Gao et al 2014, Yelenik et al 2017, and has been linked to invader traits related to exploitation and efficient use of resources, which allows for better growth (Huangfu et al 2016, Yelenik et al 2017. In our study, although competition with seedlings of both tree species reduced the total biomass of Pennisetum compared to Pennisetum grown in controls, the increase in Pennisetum biomass in response to higher soil N availability was of greater magnitude.…”

“…A focus on N physiology is warranted because N is quantitatively the most important of soilacquired nutrients (Marschner 1995), limits plant growth in most ecosystems (Agren et al 2012), drives competition (Eller and Oliveira 2017), and N availability and uptake can vary considerably in response to environmental change (BassiriRad 2000, Kuster et al 2016. Since most studies focus on biomass production as indicator of the magnitude and direction of competitive interactions, even though other factors besides competition may influence biomass, (Trinder et al 2013), we also examined net N uptake as a process that underlies the interaction between native and exotic species, because exotic species might alter soil N availability, show strong preferences to certain N forms and/or interfere with the N acquisition of native species, therefore affecting their performance (Fraterrigo et al 2011, Huangfu et al 2016, Eller and Oliveira 2017.…”

Responses to competition for nitrogen between subtropical native tree seedlings and exotic grasses are species-specific and mediated by soil N availability

Competitive interactions between native tree seedlings and exotic grasses frequently hinder forest restoration. We investigated the consequences of competition with exotic grasses on the growth and net nitrogen (N) uptake capacity of native rainforest seedlings used for reforestation depending on soil N availability and N source. Tree seedlings and grasses were grown in the greenhouse in different competition regimes (one tree species vs one grass species) and controls (grass monocultures or single tree seedlings) at low and high soil N. After 8 weeks, we quantified net N uptake capacity using 15N-labelled organic (i.e., glutamine and arginine) and inorganic (i.e., ammonium and nitrate) N sources and biomass indices. Depending on soil N availability, we observed different species-specific responses to growth and N acquisition. Tree seedlings generally increased their net N uptake capacity in response to competition with grasses, although overall seedling growth was unaffected. In contrast, the responses to competition by the grasses were species-specific and varied with soil N availability. The different N acquisition strategies suggest the avoidance of competition for N between trees and grasses. Overall, the results highlight that quantifying underlying mechanisms of N acquisition complements the information on biomass allocation as a measure of responses to competition, particularly with varying environmental conditions.
