Question

Quizplus · Accepted Answer

Parasites and pathogens can have a significant impact on plant community composition. They can reduce the growth rates and survival of certain plant species, causing a shift in the dominance of the community. This can have effects on ecosystem function and overall biodiversity. The introduction of non-native species or rapid coevolution can also have an impact, but in general, parasites and pathogens are more likely to have a direct and immediate effect. The introduction of chestnut trees is a specific example and not a general factor that affects community composition. Non-native birds can have indirect effects on plant communities through their interactions with other species and the spread of seeds, but this is less common than the impact of parasites and pathogens.
