The ability of seeds to germinate under a wide range of environmental conditions is an important characteristic of invasive alien plant species. Dunal, has been widely distributed in the Northeast and Northwest of China and is causing huge damage to the local agricultural production. Studies on seed germination and response among populations to environmental stress may assist in revealing the adaptability of invasive plants and how they cope with climate change.

Introduction: Understanding the constraints of phenotypic plasticity can provide insights into the factors that limit or influence the capacity of an organism to respond to changing environments. However, the relative effects of external and internal factors on phenotypic plasticity remain largely unexplored. Phenotypic integration, the pattern of correlations among traits, is recognized as an important internal constraint to plasticity.

Article Synopsis
- Understanding how rainfall variability affects invasive plants like Prosopis juliflora is key for managing ecosystems sustainably, especially as climate change alters precipitation patterns.
- The study evaluated the impact of low, normal, and high rainfall conditions on various physiological traits of P. juliflora over a year, using rainout shelters to simulate different rainfall scenarios.
- Results showed that while most growth metrics increased with rainfall, factors like water use efficiency and leaf nitrogen decreased with higher rainfall, indicating the plant's strong adaptability and potential invasiveness in diverse moisture conditions.
Epiphytic Fungi Can Drive a Trade-Off Between Pathogen and Herbivore Resistance in Invasive .

Trade-offs between different defense traits exist commonly in plants. However, no evidence suggests that symbiotic microbes can drive a trade-off between plant pathogen and herbivore defense. The present study aims to investigate whether the mixture of epiphytic and can drive the trade-off between the two defense traits in invasive .

Although the impacts of invasive plants on soil ecosystems are widespread, the role and impacts of invader root traits in structuring microbial communities remain poorly understood. Here, we present a macroecological study investigating how plant invaders and their root traits affect soil microbial communities, spanning data from 377 unique plots across the United States sampled multiple times, totaling 632 sampling events and 94 invasive plant species. We found that native and invasive plants harbor different root traits on average, with invasive plants possessing higher specific root lengths and native plants having higher root tissue density.
