Climate warming and anthropogenic activities have led to an increase in the prevalence of non‐native plants in mountainous regions that previously exhibited limited occurrences. This phenomenon has resulted in detrimental effects on endemic plants and ecosystem functions. However, the variation in traits of non‐native plants that successfully sprea...
High native species diversity generally suppresses non‐native invasions, but many ecosystems are now characterized by non‐native assemblages that vary in species diversity. How this non‐native species diversity affects subsequent invaders and its environmental dependence remain unclear.
We conducted a plant–soil feedback experiment. In the conditio...
Diverse native plant communities resist non‐native plants more than species‐poor communities, in part through resource competition. The role of soil biota in diversity–invasibility relationships is poorly understood, although non‐native plants interact with soil biota during invasions. We tested the responses of non‐native plants to soil biota gene...
Soil carbon (C), nitrogen (N), and phosphorus (P) are main energy and nutrient resources for soil microorganisms which are important for ecosystem functioning. Coastal reclamation, a typical land use change activity occurred worldwide, profoundly altered soil C, N, and P content. However, the relationship between soil C, N, and P ratios and microbi...
Secondary invasions in which nontarget invaders expand following eradication of a target invader commonly occur in habitats with multiple invasive plant species and can prevent recovery of native communities. However, the dynamics and mechanisms of secondary invasion remain unclear.
Here, we conducted a common garden experiment to test underlying m...
Temporal fluctuation in nutrient availability generally promotes the growth of exotic plant species and has been recognized as an important driver of exotic plant invasions. However, little is known about how the impact of fluctuating nutrients on exotic species is dependent on the availability of other resources, although most ecosystems are exper...
Fluctuating resource availability plays a critical role in determining non‐native plant invasions through mediating the competitive balance between non‐native and native species. However, the impact of fluctuating resource availability on interactions among non‐native species remains largely unknown. This represents a barrier to understanding invas...
1. Global climate change has facilitated the replacement of native species by exotic species, but the underlying causes are poorly understood. Notably, whether climatic niche differences between exotic and native species contribute to the benefits of exotic species from climate change remains unclear.
2. We investigated the relationship between tem...
Coastal reclamation is a global threat to coastal wetland ecosystems, but the impacts of coastal reclamation on belowground biodiversity and their consequences for ecosystem nutrient cycling remain poorly understood. In this study, we examined soil bacterial communities, bacterial co-occurrence pattern and soil multi-nutrient cycling index after na...
Insect herbivores can adversely impact terrestrial plants throughout ontogeny and across various ecosystems. Simultaneously, the effects of foliar herbivory may extend belowground, to the soil microbial community. However, the responses in terms of the diversity, assembly, and stability of rhizosphere fungi to aboveground herbivory remain understud...
Soil aggregate structure mediates the impacts of long-term fertilization on soil organic carbon (OC) accrual and microbiome. Recent studies have shown that microbiome structure and functioning are driven by keystone taxa irrespective of their abundance. However, whether and how carbon accrual relates to keystone taxa at the aggregate level remains...
Aim
There have been numerous studies of forest‐soil microbial biogeography, but an integrated view of edaphic factors, plant, climatic factors, and geographic distance in determining the variation of bacterial community and assembly processes remains unclear at large spatial scales. Here, we analysed the factors affecting the biogeographic pattern...
Both space and time are key factors that regulate microbial community, but microbial temporal variation is often ignored at a large spatial scale. In this study, we compared spatial and seasonal effects on bacterial and fungal diversity variation across an 878-km transect and found direct evidence that space is far more important than season in reg...
Belowground microorganisms are indispensable components for nutrient cycling in desert ecosystems, and understanding how they respond to increased salinity is essential for managing and ameliorating salinization. Our sequence-based data revealed that microbial diversity decreased with increasing salinity, and certain salt-tolerant phylotypes and ph...
Elevational gradients are associated not only with variations in temperature and precipitation, but also with shifts in vegetation types and changes in soil physicochemical properties. While large-scale elevational patterns of soil microbial diversity, such as monotonic declines and hump-shaped models, have been reported, it is unclear whether with...
Background
The relative importance of stochasticity versus determinism in soil bacterial communities is unclear, as are the possible influences that alter the balance between these. Here, we investigated the influence of spatial scale on the relative role of stochasticity and determinism in agricultural monocultures consisting only of wheat, thereb...
Rhizospheric fungi play major roles in both natural and agricultural ecosystems. However, little is known about the determinants of their diversity and biogeographic patterns. Here, we compared fungal communities in rhizosphere and bulk soils of wheat fields in the North China Plain. The rhizosphere had a lower fungal diversity (observed OTUs and C...

Soil microbial communities are influenced by climate change drivers such as warming and altered precipitation. These changes create abiotic stresses, including desiccation and nutrient limitation, which act on microbes. However, our understanding of the responses of microbial communities to co-occurring climate change drivers is limited. We surveye...
The effects of slope aspects on soil biogeochemical properties and plant communities in forested environments have been studied extensively; however, slope aspect influence on soil microbial communities remains largely unexamined, despite the central role of soil biota in ecosystem functioning. In this study, the communities of both soil bacteria a...

What's the difference between plant fitness and plant adaptation? What kind of indices can be used to represent plant fitness or plant adaptation? Thanks.
Hi there,
Does any one know how to find the congeneric native plant of a invasive one? For example, how can I know the congeneric native plant of Solidago canadensis L.? Is there any website can provide this information? Thank you.
Hello, are there anyone can guide me to estimate network stability?
I had use igraph to attack nodes on degree and betweeness order, but I found that natural connectivity increased when the proportion of removed nodes over 0.6, it was weird because the less nodes, the lower natural connectivity should be. So I wonder why there was an increase after the proportion of removed nodes > 0.6 ? Thank you for your consideration!
Hello, does anyone know how to use null model approach which utilising the neutral model of metacommunity to estimate the contributions of neutral processes to community assembly at large spatial scale? Thank you for your consideration.
Hellp everyone,
I have a question about using shotgun sequencing method to measure the plant endophytes. For plant endophytes, the plant sequences is a big obstacle. I am afraid that we measured large proportion of plant sequences which results in many invaild data. So I wonder what proportion of plant sequences and whether is it feasible to using shotgun sequencing method to measure the plant endophytes?
Thanks for your attention!

I wonder why there was a increased neutral assembly process and less phylogenetic clustering in higher salility sites. As far as I know, only these taxa can adapt to the high salinity environment are able to prevalence in higher salinity sites and the filtering effect of salinity increased in higher salinity sites as microbial diveristy decreased with increased salinity.So I suspect there was more close related taxa and increased phylogentic cluster in higher salinity sites. Hence, I am puzzling with the contradictory result. I wonder why the less phylogentic clustering occurred in higher salinity sites?
Thanks for your help.
Can anyone give me some clues about how much are the root exudation rates in temperate grassland? Thank you!
I want to calculate the distance matrix of a phylogenetic tree which is stored in R as a class “large phylo”. This tree have 23197 tips.
when I use cophenetic() to calculate the distance matrix, a error was given.
Error in double(nm * nm) : vector size cannot be NA In addition: Warning message: In nm * nm : NAs produced by integer overflow
But when I use a small phylogenetic tree to do this.
There’s no wrong!
Can any one tell me how can I fix this problem???
Thanks!
Hello , everyone. I measured the rhizospheric fungal community by ITS2 sequencing and found greater within site dissimilarity in rhizospheric compartment than thoes in bulk soil. I wonder of priority effects could be operating in rhizospheric compartment? How can I directly test the priority effects? Can I take the bulk soil as the initial state and the rhizospheric as the final state and then compare the difference between these two state? Thank you for your consideration!
The fungal ITS region varies roughly, with some exceptions, between approximately 450 and 750 base pairs (bp) in length. This feature makes it hard to compute the phylogenetic diversity. I used the tranditional method to align sequences and builded phylogenetic tree, but the bootstrap value was very low (most branches < 50%). So I suspect the tree is not robust to evaluate the fungal phylogenetic diversity. I wonder are there any feasible method to evaluate the fungal phylogenetic diveristy by ITS2 sequencing?Thank you for your kind reply.
Hello all,
I download the Tetame-2.1 in the website : http://chave.ups-tlse.fr/projects/tetame.htm. But I meet some trobule when I use the test dataset to test the TeTame2. when I enter test.txt, there was an fail information and when I enter test.txt again, the interface showing reading the file stats all the time and nothing happend after two hours. Can anyone help me to solve the problem? Thank you for your kind help!
