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

1. Identify the definition of a movement corridor in the context of ecology and conservation biology.
2. Understand that movement corridors are meant to facilitate the movement of species between fragmented habitats, promoting genetic diversity and ecosystem health.
3. Analyze each option to see which best fits the definition of movement corridors:
4. a. Focuses on migratory routes, which are specific paths animals travel seasonally, not necessarily linking fragmented habitats.
5. b. Directly mentions the connection of isolated habitat fragments, aligning with the purpose of movement corridors.

Key Concepts

Movement Corridors

Movement corridors are essential pathways that facilitate the movement of wildlife between fragmented habitats. They help maintain genetic diversity by allowing animals to migrate, find mates, and access resources. These corridors can be natural, like rivers or valleys, or human-made, such as overpasses or greenways.

Habitat Fragmentation

Habitat fragmentation occurs when large habitats are divided into smaller, isolated patches due to human activities like urban development or agriculture. This process can lead to decreased biodiversity, as species may struggle to find mates or resources, and it can disrupt ecological processes. Movement corridors are vital in mitigating these effects by connecting isolated habitats.

Ecosystem Connectivity

Ecosystem connectivity refers to the degree to which different habitats are linked, allowing for the movement of species and the flow of ecological processes. High connectivity supports biodiversity and resilience against environmental changes, while low connectivity can lead to isolated populations. Movement corridors enhance connectivity by bridging gaps between ecosystems.
