Problem 6

Textbook Question

Movement corridors are
a. The routes taken by migratory animals.
b. Strips or clumps of habitat that connect isolated fragments of habitat.
c. Landscapes that include several different ecosystems.
d. Edges, or boundaries, between ecosystems.

Verified step by step guidance

Understand the concept of movement corridors: Movement corridors are physical connections between isolated habitats that allow organisms to move between them. These corridors are crucial for maintaining biodiversity and enabling species to migrate, find resources, and reproduce.

Analyze the options provided in the problem: Each option describes a different ecological concept. For example, migratory routes (option a) refer to paths taken by animals during seasonal migrations, while edges (option d) refer to boundaries between ecosystems.

Focus on the definition of movement corridors: Movement corridors specifically refer to strips or clumps of habitat that connect isolated fragments of habitat, enabling species to traverse fragmented landscapes.

Compare the definition of movement corridors with the options: Identify which option aligns most closely with the definition of movement corridors. This involves matching the description of strips or clumps of habitat connecting isolated fragments to the correct option.

Select the correct answer based on the analysis: The correct answer is the option that matches the definition of movement corridors, which is option b.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Movement Corridors

Movement corridors are pathways that facilitate the movement of wildlife between isolated habitats. They are crucial for maintaining genetic diversity and enabling species to migrate in response to environmental changes. By connecting fragmented habitats, these corridors help prevent inbreeding and support the survival of various species.

Habitat Fragmentation

Habitat fragmentation occurs when large habitats are divided into smaller, isolated patches due to human activities or natural events. This process can lead to a decline in biodiversity, as species may struggle to find mates, food, or suitable living conditions. Understanding fragmentation is essential for conservation efforts aimed at preserving ecosystems and their inhabitants.

Ecosystem Connectivity

Ecosystem connectivity refers to the degree to which different habitats are linked, allowing for the movement of organisms and the flow of ecological processes. High connectivity enhances resilience against environmental changes and supports species migration, while low connectivity can lead to isolated populations. This concept is vital for effective conservation planning and management.
