Summary: The study found that plant chemical compounds and herbivores jointly affect plant competition through their indirect effects, which vary depending on the environment. In environments with different herbivore densities, the exotic plant Solidago altissima in Japan had a strong negative impact on co-occurring plants due to direct competition and increased herbivory, indicating that evolutionary history and local environment jointly influence herbivore-mediated indirect effects.

Summary: This study investigated the effects of the invasive plant Phytolacca americana and the exotic noninvasive Phytolacca icosandra on the native tobacco cutworm, Spodoptera litura. The findings showed that S. litura displayed a higher oviposition preference for P. icosandra and had a shorter developmental duration on this plant compared to P. americana. Additionally, S. litura feeding on P. americana exhibited higher AchE and GST activities compared to those feeding on artificial diets or P. icosandra. The content of lignin and flavonoids was relatively high in P. americana, while starch content was relatively low. These findings suggest that invasive plants have higher resistance to herbivores and suffer less damage compared to exotic noninvasive plants.

Summary: The study found that interactions involving native plants more strongly deviate from neutral predictions compared to interactions involving exotic plants. However, the proportion and composition of exotic species did not systematically alter the neutral predictions for entire networks, as only a subset of interactions were realized in different sites. This indicates that neutral and niche processes underlying individual interactions may not scale up to entire networks.

Summary: Human activities have led to the exchange of species across different parts of the world. Introduced species that become naturalized and invasive can have significant negative impacts on the environment, human societies, biodiversity, and ecosystem structure. Understanding the phylogenetic relatedness of native and non-native species, as well as among non-native species at different stages of invasion, can contribute to the understanding of the drivers behind species invasion.

Summary: This study investigates the impact of incorporating the exotic plant Plantago lanceolata into the diet of the herbivorous insect Anartia jatrophae on its immune performance, development, and susceptibility to pathogen infection. The results show that herbivores reared on P. lanceolata exhibit higher survival rates and lower viral burdens when infected with a pathogenic virus, suggesting diet-mediated protection against disease as a potential mechanism facilitating the incorporation of novel resources.

Summary: Many landscapes worldwide are dominated by non-native plant species, which can have direct impacts on native species including insect herbivores. Native butterfly species are often reported to use exotic host plants, and these interactions can have diverse effects on butterfly populations. Recent developments in the study of the effects of exotic host plants on butterflies have focused on the genetic basis of host use and the influence of other trophic levels on butterfly-plant interactions. Understanding how these factors interact is crucial for predicting whether an exotic plant will be beneficial or detrimental for herbivorous insects.

Summary: Urban areas often have exotic plant species, which may affect pollinator diversity and pollination networks. However, exotic plants in cities also provide additional flower resources during periods of scarcity, and their impact on seasonal dynamics of networks needs further investigation.

Summary: This study focuses on the behavior of phoretic mites in selecting the correct host for habitat and mate selection. The results show that the Lasioseius mites are not strict specialists, but are able to detect and attach to beetle species that inhabit their host plant.

Summary: Plant root traits, such as root diameter and native/exotic status, strongly influence the composition of arbuscular mycorrhizal fungal communities. Coarse-rooted plants have a lower diversity of mycorrhizal fungi and associate less with generalist fungal partners compared to fine-rooted plants. Exotic plants have a lower diversity of fungi and fewer associations with nondominant families of arbuscular mycorrhizal fungi compared to native plants.

Summary: Research suggests that rising temperatures may cause declines in many native annual plant species, highlighting the need for adaptive management practices to facilitate their restoration or introduction to newly suitable locations. Frequent and intense disturbances are critical to reduce competitors and promote the persistence of native annuals, but such efforts may prove futile under future climate regimes.

Summary: The study in North-eastern Madagascar found that land-use change influences plant diversity, with unburned land-use types having higher endemic species richness. Native and exotic species richness increased with land-use intensity, while endemics decreased. Old-growth forests and forest fragments are crucial for maintaining endemic herbaceous plants.

Summary: The study found that the characteristics of different host plants and abiotic factors can affect the survival rate and performance of herbivorous insects, especially in field conditions. Therefore, when considering plant-herbivore interactions, the origin of the host plant and multiple ecological factors in natural environments should be taken into account.

Summary: This study examines the indirect effects of exotic plants on native plants through pollinator-mediated interactions. The study finds that the presence of exotic plants can positively affect the pollination of native plants, but this effect is influenced by geographical differences and interactions with exotic herbivores.

Summary: Ash trees in the northeastern USA are rapidly declining due to the invasive emerald ash borer. Three nonnative shrubs that co-occur with ash trees may serve as alternative larval host plants for ash-reliant Lepidoptera. In this study, the performance of ash-specialist hawkmoths on native white ash and alternative host plants was measured. The results showed that the nonnative host plants provided varied support for larval survival, with some caterpillars experiencing malformations when reared on European privet. These findings highlight the importance of considering alternative host plants to support threatened insect species during native host decline.

Summary: The reproductive success of individuals is influenced by random events and changing probabilities in variable environments. Research shows that birth environment and stage impact the random distribution of reproductive success, providing a null model to quantify the effects of birth size or stage on reproductive success. The study using Roe deer as a case study reveals that an individual's birth environment affects reproductive success depending on the frequency and temporal autocorrelation of environments, with lifetime performance being influenced by changes in environmental patterns due to climate change.
