Biodiversity and Conservation Challenges

The video discusses the decline in terrestrial biodiversity, focusing on human-induced factors. It introduces the HIPKO acronym, detailing habitat alteration, invasive species, pollution, climate change, and overharvesting as key causes. The impact of climate change on species migration is highlighted, with examples like the polar bear. The video also covers the illegal trade of endangered species and international efforts like CITES and national policies like the Endangered Species Act to combat these issues.

What does the acronym HIPKO stand for in the context of biodiversity decline?

• Habitat destruction, Invasive species, Population growth, Climate change, Overharvesting

• Habitat alteration, Invasive species, Population growth, Climate change, Overharvesting

• Habitat destruction, Invasive species, Pollution, Climate change, Overharvesting

• Habitat alteration, Invasive species, Pollution, Climate change, Overharvesting

Which of the following is NOT a way habitats are altered by human activities?

• Natural disasters like hurricanes

• Conversion of forests to farmland

• Fragmentation into smaller habitat islands

• Simplification of diverse ecosystems

Which of the following is a consequence of habitat simplification?

• Improved habitat resilience

• Creation of new ecological niches

• Increased biodiversity

• Loss of species that require diverse habitats

Why are invasive species a significant threat to native species?

• They require more resources than native species

• They often have no natural predators in new habitats

• They are always introduced deliberately

• They are always larger than native species

What is a common characteristic of invasive species?

• They require specific environmental conditions

• They often outcompete native species

• They thrive in undisturbed habitats

• They are always smaller than native species

How does climate change contribute to species decline?

• By increasing the number of natural disasters

• By causing species to migrate beyond their tolerance range

• By reducing the amount of available sunlight

• By increasing the number of invasive species

What is the primary focus of the CITES treaty?

• To reduce carbon emissions

• To promote sustainable agriculture

• To protect marine ecosystems

• To ban the trade of endangered species

Which act was passed in the United States to prevent illegal trade of wildlife?

• The Marine Mammal Protection Act

• The Clean Air Act

• The Lacy Act

• The Endangered Species Act

What is the main reason for the illegal poaching of endangered species?

• To promote conservation efforts

• To increase biodiversity

• To reduce population growth

• To fulfill demand in developed countries

Which federal agencies are charged with protecting endangered species in the U.S.?

• U.S. Forest Service and Bureau of Land Management

• National Marine Fisheries Service and National Wildlife Service

• Fish and Wildlife Service and Environmental Protection Agency

• Environmental Protection Agency and National Park Service
