How do invasive species affect ecosystem functioning and biodiversity?

Invasive species can have detrimental effects on ecosystem functioning and biodiversity.

Invasive species are non-native organisms that have been introduced to a new environment and have the potential to cause harm to the ecosystem. They can outcompete native species for resources, alter the physical environment, and disrupt ecological processes. This can lead to a decrease in biodiversity as native species are replaced or eliminated.

Invasive species can also affect ecosystem functioning by altering nutrient cycling, pollination, and seed dispersal. For example, the introduction of the Asian long-horned beetle in North America has led to the destruction of millions of trees, which has impacted carbon storage and nutrient cycling in affected ecosystems.

Furthermore, invasive species can have economic impacts, such as reducing crop yields or increasing the cost of controlling their spread. Invasive species can also have negative impacts on human health, such as the spread of diseases by invasive mosquitoes.

Overall, invasive species pose a significant threat to ecosystem functioning and biodiversity. It is important to prevent their introduction and control their spread to protect native species and maintain healthy ecosystems.
