Understanding Alien Species and Their Impact

The video discusses the increasing global travel and trade, leading to the introduction of non-native species to new regions. These alien species can become invasive, causing harm to the environment, economy, and health. The video highlights research efforts like the EU-funded Alien Challenge and Alien CSI projects, which aim to monitor and understand these species. It encourages public involvement in reporting sightings and maintaining biosecurity to prevent further invasions.

What is a potential consequence of increased global travel and trade?

• Introduction of non-native species to new regions

• Stabilization of local ecosystems

• Decrease in global commodity access

• Reduction in global biodiversity

What term is used for species that cause harm in new environments?

• Domestic species

• Endemic species

• Native species

• Invasive alien species

How have alien species introductions changed over the last 200 years?

• They have become less impactful

• They have increased dramatically

• They have remained constant

• They have decreased significantly

What is a major factor contributing to the introduction of alien species?

• Natural migration patterns

• Climate change

• Global trade networks

• Local farming practices

What was the purpose of the EU-funded project Alien Challenge?

• To promote global trade

• To eradicate all alien species

• To compile and harmonize information about alien species in Europe

• To study climate change effects

What is the goal of the COST Action called Alien CSI?

• To increase understanding of alien species through citizen science

• To develop new trade routes

• To reduce global travel

• To promote local species

How can individuals help prevent the spread of invasive alien species?

• By increasing global travel

• By supporting local trade only

• By reporting sightings of alien species

• By ignoring biosecurity measures

What is the COST programme focused on?
