The video introduces the Duke of Burgundy butterfly, highlighting its population decline due to habitat loss from human activities. It explains that many butterflies, including the Duke of Burgundy, have limited flight capabilities, making them vulnerable to habitat fragmentation. The video discusses the concept of habitat bridges, which help butterflies access new habitats, thus increasing their food and mate options. Conservation efforts, including habitat bridges, have successfully increased the Duke of Burgundy's population by 90% since 2003.

What is the primary reason for the decline in the Duke of Burgundy butterfly population?

• Loss of grassland habitat due to farming

• Predation by birds

• Climate change

• Introduction of invasive species

Why might a bridge seem unnecessary for a flying animal like a butterfly?

• Butterflies can fly wherever they want

• Butterflies can fly long distances without rest

• Butterflies do not need specific habitats

• Butterflies can fly over oceans

What is a common characteristic of butterflies that struggle with habitat fragmentation?

• They fly very high

• They migrate long distances

• They stick to smaller areas

• They are nocturnal

How far does the Duke of Burgundy butterfly typically fly from its home?

• Less than 100 meters

• More than 1 kilometer

• Around 200 meters

• Over 500 meters

What is a significant problem for butterflies when they are cut off from other habitats?

• Increased predation

• Lack of sunlight

• Limited access to food and mates

• Excessive rainfall

What is the purpose of a habitat bridge?

• To serve as a tourist attraction

• To provide a resting place for birds

• To connect fragmented habitats for butterflies

• To block human traffic

What form can habitat bridges take?

• Deep tunnels

• Artificial lakes

• Literal bridges over highways

• Tall buildings

What has been the impact of habitat bridges on the Duke of Burgundy butterfly population?

• Population grew by 90%

• Population decreased by 50%

• Population became extinct

• Population remained stable

When did conservation efforts for the Duke of Burgundy begin?

• 1990

• 2003

• 2010

• 2015

What was a key factor in helping the Duke of Burgundy butterfly recover?

• Increasing pesticide use

• Reducing sunlight exposure

• Building habitat bridges

• Introducing new predators
