Ecosystem Dynamics and Wolf Management

The video discusses the long-term wolf-moose study on Isle Royale, highlighting the impact of climate change on ice bridges and the resulting genetic issues in the wolf population. It explores the consequences of reduced predator numbers on moose populations and forest health. The video also delves into the complexities of managing wilderness areas, balancing human intervention with natural processes, and the role of top predators in maintaining ecosystem balance. The importance of understanding the distinction between National Parks and Wilderness Areas is emphasized, along with the need for informed decision-making in ecosystem management.

What is the primary focus of the Isle Royale wolf-moose research project?

• To monitor the migration patterns of birds

• To analyze the effects of pollution on the ecosystem

• To understand the fluctuations in wolf and moose populations

• To study the impact of tourism on wildlife

How has climate change indirectly affected the wolf population on Isle Royale?

• By causing more frequent storms

• By reducing the availability of prey

• By increasing the number of predators

• By affecting the formation of ice bridges

What is the relationship between Lake Superior's ice formation and climate change?

• Ice formation is unaffected by climate change

• Warmer winters lead to more ice formation

• Colder winters result in less ice formation

• Ice formation is sensitive to small temperature changes

What complicates intervention decisions in Isle Royale National Park?

• Limited funding for conservation

• Lack of scientific data

• Conflicting policies on wilderness management

• The park's remote location

What was the agreed approach to managing the wolf population on Isle Royale?

• To continuously monitor and intervene

• To restart the population and minimize future intervention

• To let the population decline naturally

• To relocate wolves to other areas

What ecological changes occurred in Yellowstone due to the absence of wolves?

• Stabilization of the ecosystem

• Increased biodiversity

• Decline in elk population

• Expansion of grasslands and woody vegetation

What is the main goal of the Wilderness Act?

• To develop infrastructure in wilderness areas

• To allow unrestricted human intervention

• To protect the wild character of areas

• To promote tourism in national parks

Why is human intervention sometimes necessary in maintaining ecosystem health?

• To increase tourism revenue

• To prevent natural disasters

• To counteract previous human impacts

• To promote urban development

What is a potential risk of the Isle Royale wolf experiment?

• Causing the extinction of moose

• Setting a precedent for increased human manipulation

• Decreasing biodiversity in the park

• Increasing the wolf population uncontrollably

What is a key consideration in deciding when to intervene in natural ecosystems?

• The number of tourists visiting

• The availability of funding

• The best scientific knowledge available

• The popularity of the park
