Summary: This study reveals that the invasive plant Spartina alterniflora exhibits plasticity in light use, reducing intraspecific competition and increasing biomass production. Shorter individuals show higher light-use efficiency and specific leaf area in response to reduced light intensity, while taller individuals do not exhibit this ecophysiological plasticity.

Summary: Empirical observations in a Mediterranean grassland over five years show that spatial heterogeneity plays a minor role in the relationship between species richness and area, while direct pairwise interactions drive species coexistence. A small set of transient species with small population sizes are consistently found across spatial scales, highlighting the importance of species interactions and stochastic events in coexistence and species-area relationships.

Summary: Increasing evidence suggests that the ability of invasive populations to rapidly adapt to novel environments depends on genetically-based trait variation and covariation. However, few studies have investigated the trait covariance in both native and invasive ranges. This investigation provides a more comprehensive understanding of how historical contingency and adaptation shape invasiveness, contributing to the prediction of future invasion dynamics.

Summary: Plants growing at high densities interact via various pathways, with individual plants perceiving neighbor-induced changes in light quality and quantity mainly through phytochromes. These interactions lead to shade avoidance responses and architectural adjustments, impacting canopy structure, species composition, and population fitness within the plant community.

Summary: Exploring the influence of abiotic environment on microbial invasion is crucial in microbial ecology. Soil pH, as an important variable, plays a significant role in shaping microbial community and controlling microbial multifunctionality. However, the mechanism by which pH determines invasion success remains unclear. Through a series of experiments, it was found that the invader's pH fitness did not consistently correlate with invasion success. In contrast, the pH fitness of residential members had a major impact on the abundance of established pathogens and the outcome of plant disease.

Summary: This study investigates the impact of changing precipitation on competitive dynamics between species in a California grassland community. The results demonstrate that reduced precipitation alters the outcome of species competition, particularly for functionally diverse communities. Thus, considering changes in species interactions is crucial when predicting species and community responses to global change.

Summary: The study found that soil heterogeneity can alleviate the competitive effects of native communities on alien invaders, as the invaders benefit more from resource-rich patches. This finding could explain why observational studies often find positive relationships between the numbers of alien and native species.

Summary: The impact of garlic mustard removal on the plant community composition supports the hypothesis of disruption of mutualistic interactions, especially for mycorrhizal plant species. This demonstrates that allelochemical producing invaders can significantly alter the community composition by disproportionately affecting mycorrhizal plant species.

Summary: This study investigated the effect of clonal integration on the growth and chlorophyll content index of the invasive clonal plant Alternanthera philoxeroides and the native species A. sessilis under different nutrient patch environments. The results showed that clonal integration significantly improved the growth of both species, with a greater positive effect observed in A. philoxeroides. Clonal integration also increased the chlorophyll content index of A. philoxeroides and the growth of basal ramets under high and low contrast patches. Overall, this study suggests that clonal integration may give invasive clonal plants a competitive advantage over native species in patchy habitats, especially in environments with higher heterogeneity.

Summary: The study suggests that invasive plants impact native plant communities not only through competitive displacement, but also through ecosystem modifications such as altering soil nutrients and pH levels. Both competitive displacement and ecosystem modifications can have negative effects on plant biodiversity.

Summary: This article explores how remote sensing technologies can be used to infer plant-plant interactions and their roles in shaping plant-based systems at different levels, including individual, community, and landscape. Remote sensing data can detect the key attributes of ecosystems derived from plant-plant interactions. By combining remote sensing techniques with theories, models, experiments, and data analysis algorithms, we can better understand biotic interactions and scale ecological patterns.

Summary: The Musk thistle, a major noxious weed, is controlled by the flower head weevil, which responds variably to plant characteristics, impacting its effectiveness in biological control. Larger flower heads provide more oviposition sites but also result in more seed production, offsetting the efficacy of the weevil's control.

Summary: Climate warming leads to advanced reproductive phenology in an invasive plant, accelerating its life cycle and population growth rate. Rising temperatures increase the average size of reproducing individuals, the proportion of survivors that reproduce, and the fraction of individuals reproducing as annuals, all contributing to the accelerated population growth of invasive species.

Summary: The authority to manage natural capital often follows political boundaries rather than ecological boundaries, which can lead to unsustainable outcomes due to mismatch. The trade-offs between federal vs. state control of renewable resources involve factors such as biological mechanisms, economic mechanisms, flexibility in federal management, spatial and temporal distribution of economic returns. The analysis reveals the complex political economy dimensions of renewable resource federalism.

Summary: This study examines the effects of disturbances on species diversity and proposes a classification method for pulse and press disturbances. The research found that the two types of disturbances have different impacts on coexistence mechanisms, although their asymptotic diversity patterns are similar. Furthermore, the study emphasizes the importance of using theoretical modeling to guide and interpret empirical research.

Summary: Climate change affects weed performance and may impact management practices to control pests. A field experiment on musk thistle showed that under elevated temperatures, thistles were more likely to survive mowing, flowered earlier, grew taller, and produced more flowers. Proportional reductions in height and flower production caused by mowing were smaller under warming. Warming increased population growth rate for all mowing treatments. To achieve similar outcomes in the future, supplemental management may be needed.

Summary: The invasion of non-native species can have a significant impact on the function and structure of ecological communities. Whole community invasion leads to more stable communities with a higher retention of native species and smaller changes in topological measures. Mutualistic interactions act as a buffer against disruptions to the native community.
