Climate Change and Invasive Species

The video discusses the impact of climate change on ecosystems, highlighting how rising global temperatures and drought conditions weaken ecosystems, making them vulnerable to invasive species. It provides examples of pine beetle infestations in the Western US and emerald ash borer threats in hardwood forests. Additionally, it covers the migration of native species in the Sonoran Desert due to climate change, leading to the invasion of buffelgrass, which alters the ecosystem.

What is one of the main consequences of climate change on ecosystems as discussed in the first section?

• Improved water transport in trees

• Decrease in global temperatures

• Rise in global temperatures and drought conditions

• Increased resistance to invasive species

How do pine beetles affect pine trees?

• By protecting them from other insects

• By providing them with nutrients

• By blocking their water and nutrient transport systems

• By enhancing their growth

What is the origin of the emerald ash borer?

• Europe

• Africa

• Asia

• South America

What has allowed the emerald ash borer to proliferate in the US?

• Milder winters and drier conditions

• Colder winters

• Stronger trees

• Increased rainfall

What invasive species is altering the Sonoran Desert ecosystem?

• Kudzu

• Water hyacinth

• Buffelgrass

• Japanese knotweed
