Problem 6 - Campbell Biology

Question

Application/Analysis Of the following statements about protected areas that have been established to preserve biodiversity, which one is not correct? (A) About 25% of Earth's land area is now protected. (B) National parks are one of many types of protected areas. (C) Management of a protected area should be coordinated with management of the land surrounding the area. (D) It is especially important to protect biodiversity hot spots.

Step-by-Step Solution

Answer

Statement (A) is not correct.

Step 1 - Understand the Question

Read the question carefully to determine what it is asking. The question is asking to identify the incorrect statement regarding protected areas established to preserve biodiversity.

Step 2 - Analyze Statement (A)

Statement (A) claims that about 25% of Earth's land area is now protected. Research or recall that the actual percentage of protected land is much lower. This statement is likely incorrect.

Step 3 - Analyze Statement (B)

Statement (B) claims that national parks are one of many types of protected areas. This is a true statement; national parks are indeed a type of protected area.

Step 4 - Analyze Statement (C)

Statement (C) states that the management of a protected area should be coordinated with the management of the surrounding land. This is correct and important for the ecosystem's health.

Step 5 - Analyze Statement (D)

Statement (D) claims that it is particularly important to protect biodiversity hot spots. This is also true because these areas have a high level of biodiversity and are often under threat.

Step 6 - Conclude the Incorrect Statement

Based on the analysis, it's clear that statement (A) is the incorrect one.

Key Concepts

protected areas

Protected areas are regions set aside to conserve wildlife and natural resources. From national parks to wildlife reserves, these areas play a key role in preserving biodiversity. They provide a safe haven for species to thrive without the threats posed by human activities. The main goals of protected areas are:

• Conservation of biodiversity
• Protection of endangered species
• Maintenance of natural ecosystems

It's crucial to manage these protected areas effectively. This includes preventing illegal activities like poaching and deforestation. By maintaining these areas, we help ensure that ecosystems and their inhabitants can continue to flourish.

biodiversity hot spots

Biodiversity hot spots are regions with exceptionally high levels of species richness and often a large number of endemic species—species found nowhere else on Earth. Protecting these areas is critical, as they are often highly threatened by human activities such as habitat destruction and climate change. Some characteristics of biodiversity hot spots include:

• High levels of endemic species
• Significant threats from human activities
• Crucial for global conservation efforts

To effectively protect these hot spots, conservation strategies may include establishing protected areas, restoring habitats, and engaging local communities to support conservation initiatives. Ensuring the safeguarding of biodiversity hot spots is vital for maintaining global biodiversity.

ecosystem management

Ecosystem management involves taking an integrated approach to managing natural resources, balancing the needs of both humans and wildlife. The objective is to sustain healthy ecosystems that can provide goods and services for future generations. Key principles of ecosystem management include:

• Maintaining viable populations of native species
• Sustainable use of natural resources
• Understanding ecosystem processes and interactions

This approach often requires coordinating the management of protected areas with the surrounding lands to ensure ecological integrity. For example, forest management outside a national park can influence the health of the park’s ecosystems. Effective ecosystem management seeks to maintain biodiversity, protect water resources, and mitigate climate change impacts, creating a balanced and sustainable environment for all species.
