Summary: After infection by Puccinia spegazzinii, the levels of plant growth-promoting hormones were significantly reduced, while the levels of jasmonic acid (JA) and jasmonoyl-isoleucine (JA-Ile) increased substantially. This may result in a decrease in the accumulation of the defense hormone salicylic acid (SA) and affect plant growth hormones, carbon, and nitrogen metabolic pathways, thereby impeding the rapid growth of Mikania micrantha.

Summary: Mikania micrantha Kunth is a serious invasive alien plant, and its adventitious roots play a crucial role in promoting plant growth and nutrient availability. Increasing number of nodes with adventitious roots benefits plant growth and enhances nutrient content in M. micrantha.

Summary: The study found that the successful invasion of Mikania micrantha in southern China is closely related to gene flow, environmental variables, and functional genes. The populations exhibited high genetic diversity not constrained by latitude and longitude, indicating multiple introductions and rapid-range expansion with high gene flow. Environmental variables such as soil composition, temperature, precipitation, and ecological factors played important roles in the invasive adaptation of M. micrantha, with specific outlier SNPs identified. Candidates genes related to abiotic stress response were identified, as well as gene families unique to M. micrantha and genes under positive selection. These findings highlight the influence of gene flow, adaptive loci, and functional genes in the invasion and spread of Mikania micrantha.

Summary: The study found a high level of perception of M. micrantha among stakeholders, with socio-demographic factors playing a significant role in perception. Managers showed higher scores in identification, damage, control measures, and manual treatment of M. micrantha compared to non-managers, indicating perception gaps between the two groups. Educational approaches, especially training workshops, were identified as effective in improving stakeholder perception of IAS.

Summary: This study aims to investigate the ability of four grass species, particularly P. incomtum and P. purpureum, to prevent the invasion of M. micrantha. The results suggest that these grasses have potential as bio-control agents for M. micrantha.

Summary: Invasive plants are suitable for biochar production, with temperature and plant species having interacting effects on biochar properties. Biochars pyrolyzed at 500 and 700 degrees Celsius exhibit high metal adsorption capacity in neutral solutions.

Summary: During range expansion, invasive plants may develop distinctive traits like rapid growth rate and high seed dispersal ability, allowing them to quickly occupy suitable and empty sites. However, little is known about the evolution of competitive ability and the changes in stand biomass during range expansion. In this study, the competitive ability and stand biomass of an invasive plant, Mikania micrantha, were examined along its invasion route on Hainan island of China. The results showed that competitive ability and stand biomass did not correlate with distance from the invasion center. However, stand biomass was negatively correlated with distance in habitats with thick soil layers, suggesting reduced performance of edge populations in such habitats.

Summary: Genomic research on North American starlings indicates low geographical differentiation and few significant F-ST outliers at a continental scale, despite their high dispersal rate and rapid expansion history. Despite starting from a relatively small founding population, these birds show only moderate genetic bottleneck and a dramatic increase in effective population size since introduction. Furthermore, single-nucleotide polymorphisms correlated with temperature and/or precipitation suggest rapid local adaptation in North American starlings even in their wide-ranging and evolutionarily young system.

Summary: This study explored the spatial distribution of genetic diversity in European chestnut cultivars in Southern Italy using spatial representation. Principal Coordinates Analysis (PCoA) revealed varietal groups with high genetic diversity. A Geographic Information System (GIS) tool was then used to create a genetic divergence surface based on molecular-genetic data, allowing for differentiation of regions with higher and lower biodiversity richness. The combination of molecular and spatial analysis tools provides valuable information for the conservation of endangered chestnut biodiversity.

Summary: The genetic paradox of invasive species, which refers to their ability to rapidly adapt to novel environments, can be explained by the activity of transposable elements (TEs). Mikania micrantha serves as a good example to test this explanation, as shown in a study of 21 invasive populations in southern China. The research found that M. micrantha populations exhibit high levels of TE-related genetic and epigenetic variation, and are differentiated into subpopulations.

Summary: A study on invasive common starlings in Australia revealed genetic differentiation and responses to selective pressures, with isolation by distance playing a significant role in genetic substructure. Factors such as aridity, precipitation, and temperature were found to potentially drive adaptive variation in the starling's invasive range. Historical introduction regimes may impact sites under adaptive selection, highlighting the importance of critical interpretation of selection analyses in non-native populations.

Summary: In this article, a novel multisource domain adaptation method is proposed for machinery fault diagnosis under different working conditions. This method transfers information from multisource domains to the target domain using multisource feature alignment and adversarial learning. It also develops an ensemble classifier to make full use of multisource domains information. The method utilizes a discrete cosine convolutional block for noise reduction. Experimental results show that the proposed method outperforms other transfer learning methods in fault diagnosis.

Summary: Two fundamental questions in evolutionary studies are the speed of evolution and its manifestation in an organism's genome. Research on invasive populations, such as the invasive European starlings in Australia, can provide insight into the mechanisms behind rapid adaptation and population persistence in novel environments. Recent developments in experimental and sequencing technologies have facilitated the investigation of these questions, particularly with the accessibility of next generation sequencing.
