Why some plant species can co occur with invasive plants? 


Best insight from top research papers

Some plant species can co-occur with invasive plants due to various factors such as phylogenetic relationships, competitive interactions, and biotic homogenization. Invasive species may succeed in introduced regions by being phylogenetically related to native species or by occupying unfilled niches, as seen in the case of Anthemis cotula L.. Additionally, competitive interactions between native and invasive species, influenced by traits like biomass, morphological characteristics, and photosynthetic traits, can impact their coexistence. Furthermore, invasive plant species can become integrated within frugivory networks, playing similar roles to native species, which can lead to biotic homogenization in ecosystems like the Brazilian Atlantic Forest. These interactions highlight the complex dynamics that allow certain plant species to co-occur with invasive plants in various ecological settings.

Why do some plant species can coexist with invasive plants in soil seedbanks?4 answersSome plant species can coexist with invasive plants in soil seed banks due to various factors such as seed bank properties, seed viability, and habitat characteristics. Studies have shown that the ability to form persistent seed banks is strongly associated with naturalization and invasiveness. In urban regions of Indian dry tropics, the seed bank flora showed minor similarity with standing vegetation, indicating a minor role in regeneration, while anthropogenic activities significantly influenced seed bank composition. Alien plant species like Cornus alba and C. sanguinea subsp. australis formed denser and more viable seed banks compared to native species, contributing to their invasiveness. Movement of seed-contaminated soil has been identified as a significant source of local non-native species spread in subarctic habitats. Understanding seed bank dynamics is crucial for managing invasive species and conserving biodiversity.
What are some examples of alien plants for which increased genetic diversity through hybridization was important in the invasion?5 answersHybridization leading to increased genetic diversity has played a crucial role in the invasion success of certain alien plant species. For instance, the invasive fungal plant pathogen Heterobasidion irregulare has been hybridizing with its native sister species H. annosum, resulting in the introgression of alleles that enhance fitness and invasiveness. Similarly, in the case of Cakile species, C. edentula and C. maritima, hybridization has been observed during range expansion, with evidence of high levels of hybridization in invaded regions, contributing to the replacement of one species by another. These examples highlight how hybridization and increased genetic diversity through introgression have been important factors in the successful invasion of certain alien plant species.
Definition of invasive species?5 answersAn invasive species refers to a non-native plant or animal introduced to an environment where it is not native, causing harm to the ecosystem and native species.

The impact of invasive species on biodiversity is a global problem that requires efficient control and integrated management.
How are climate change and invasive species related?4 answersClimate change and invasive species are related in several ways. Climate change can increase the possibilities of invasion, making endemic species vulnerable to its effects. Changes in temperature and rainfall patterns caused by climate change can affect the distribution and dominance of invasive species, allowing them to become more dominant in many areas. Climate change can also facilitate alien plant invasions by altering environmental conditions, increasing disturbance through extreme weather events, and influencing human responses. On the other hand, invasive species can exacerbate the impacts of climate change on ecosystems, and climate change can allow new invasions to occur. Climate change is predicted to affect the distribution of invasive species, with some species experiencing range decreases while others expand their ranges. Overall, climate change and invasive species interact and can have significant impacts on biodiversity and ecosystem services.
