What is common to the species Lantana, Parthenium and African catfish?...
Common Trait:
Invasive Species:
- The common trait among the species Lantana, Parthenium, and African catfish is that they are all invasive species.
- Invasive species are non-native organisms that have been introduced to a new environment and have the potential to cause harm to the native ecosystem, economy, or human health.
- These species often outcompete native species for resources, disrupt ecological balance, and can lead to negative impacts on biodiversity.
Lantana:
- Lantana is a highly invasive plant species that is native to tropical regions of the Americas.
- It has been introduced to many countries around the world and has become a problematic weed in areas such as Australia, India, and South Africa.
- Lantana can form dense thickets, outcompeting native vegetation and reducing biodiversity.
Parthenium:
- Parthenium, also known as Congress grass or carrot weed, is a highly invasive weed native to the Americas.
- It has spread to several countries, including India, where it is a major weed problem.
- Parthenium can cause allergic reactions in humans and livestock, and its rapid spread can have negative impacts on agriculture and the environment.
African Catfish:
- The African catfish, also known as the Clarias gariepinus, is an invasive fish species that has been introduced to many countries for aquaculture purposes.
- It can outcompete native fish species, disrupt aquatic ecosystems, and have negative impacts on local fish populations.
- African catfish have been introduced to countries in Asia, including India, where they have become established in freshwater habitats.
Conclusion:
In conclusion, Lantana, Parthenium, and African catfish share the common trait of being invasive species that have negative impacts on the environments in which they have been introduced. It is important to manage and control these species to prevent further harm to native ecosystems.
What is common to the species Lantana, Parthenium and African catfish?...
When alien species are introduced unintentionally or deliberately for whatever purpose, some of them turn invasive, and cause decline or extinction of indigenous species. The Nile perch introduced into Lake Victoria in east Africa led eventually to the extinction of an ecologically unique assemblage of more than 200 species of cichlid fish in the lake.
- Environmental damage is caused and threat is posed to our native species by invasive weed species like carrot grass (Parthenium), Lantana and water hyacinth (Eicchornia). The recent illegal introduction of the African catfish (Clarias gariepinus) for aquaculture purposes is posing a threat to the indigenous catfishes in our rivers.
- Hence option (c) is the correct answer.
