Elevated temperatures and drought may exacerbate invasion success of non-native grasses, as non-native species often possess traits favored by a warmer, drier world. In our study, we assessed plant traits potentially linked to invasion success under elevated temperature and drought, including biomass production, reproductive allocation, arbuscular mycorrhizal (AM) fungal root colonization, and germination of native grasses and non-native invasive grasses. We selected two caespitose warm-season…

Belowground mechanism reveals climate change impacts on invasive clonal plant establishment

Climate change and disturbance can alter invasion success of clonal plants by differentially affecting the clonal traits influencing their establishment as young plants. Clonal traits related to the

Effect of drought and nutrient availability on invaded plant communities in a semi‐arid ecosystem

Abstract Ecosystem functions are heavily dependent on the functional composition of the plant community, i.e., the functional traits of plants forming the community. This, on the one hand, depends on



Above- and below-ground responses of native and invasive prairie grasses to future climate scenarios1

The goal of this research was to assess above- and below-ground production and mycorrhizal fungal abundance of functionally similar native and invasive non-native grass species under projected climate-change scenarios.

Invasive warm-season grasses reduce mycorrhizal root colonization and biomass production of native prairie grasses

The results indicate that a major mechanism in plant growth suppression following invasion by Bothriochloa spp.

Effect of drought on biomass allocation in two invasive and two native grass species dominating the mixed-grass prairie.

The effect of drought stress on biomass allocation manifested itself more on rhizomes or crowns than on roots or shoots of the four studied grass species, with the effects species-specific in nature.

Testing Disturbance, Seeding Time, and Soil Amendments for Establishing Native Warm‐Season Grasses in Non‐Native Cool‐Season Pasture

This research demonstrates that burning facilitates and nutrient enrichment inhibits native warm-season grass reintroduction and establishment into non-native cool- season grass dominated pastures.

Soil amendment interacts with invasive grass and drought to uniquely influence aboveground versus belowground biomass in aridland restoration

Water‐holding soil amendments such as super‐absorbent polymer (SAP) may improve native species establishment in restoration but may also interact with precipitation or invasive species such as Bromus

Plant functional traits of dominant native and invasive species in mediterranean-climate ecosystems.

It is found that species invading mediterranean-climate regions were more likely to be annual than perennial: three of the five regions were dominated by native woody species and invasive annuals, which contradicts the widespread idea that invasive species optimize resource acquisition rather than resource conservation.

Climate Affects Plant-Soil Feedback of Native and Invasive Grasses: Negative Feedbacks in Stable but Not in Variable Environments

The plant-soil feedback framework allows researchers to target the interaction of plants and root-associated microbes and to determine its interplay on plant-plant interactions. Plant-soil feedbacks

Alien plant species favoured over congeneric natives under experimental climate warming in temperate Belgian climate

A study to experimentally compare responses to warming in native and alien plant species, finding that native species became less productive in the warmer climate, whereas their alien counterparts showed no response.

Exotic species display greater germination plasticity and higher germination rates than native species across multiple cues

Exotic species had more rapid and prolific germination across a variety of environmental cues and in response to increased resource availability compared with native species, indicating both germination plasticity and robustness.

Arbuscular Mycorrhizal Fungi Alleviate Drought Stress in C3 (Leymus chinensis) and C4 (Hemarthria altissima) Grasses via Altering Antioxidant Enzyme Activities and Photosynthesis

An in situ rainfall exclusion experiment was conducted in a temperate meadow in northeast China and showed that AMF significantly reduced the negative effects of drought on plant growth, highlighting potential photosynthetic type differences in the magnitude of AMF-associated enhancement in plant drought resistance.
